The car stopped both Level 1 and 2 charging. But Level 3 charging worked. When it stopped in the middle of Level 2 charging, it tripped my circuit and bricked my Juicebix Level 2 charger. Hyundai replaced the ICCU.

The contact owns a 2022 Hyundai Ioniq 5. The contact stated that the vehicle was repaired under NHTSA Campaign Number: 24V868000 (Electrical System); however, the repair failed to prevent a failure from occurring shortly afterwards. The contact stated that while driving at 55 MPH, the vehicle was rattling abnormally. The vehicle was taken back to the same local dealer where it was diagnosed, and determined that all four tires needed to be replaced. The four tires were replaced. In addition, the contact stated that while driving at 35 MPH, the instrument panel abnormally illuminated. The vehicle was towed to the local dealer where the vehicle was originally purchased. The vehicle was later towed back to the same local dealer and diagnosed with a leak that contaminated the rear inverter. The vehicle was not repaired due to the costs and the warranty being invalid. The manufacturer was made aware of the failure. The failure mileage was approximately 132,000.

The car would not charge. The Dealership where the car was bought assessed the problem and found out that the Integrated Charging Control Unit (ICCU) of the car had failed. They already replaced the component, however I am reporting this problem so as to be included in the statistics for this common problem with this Hyundai make.

While charging at home with provided Level 1 Charger, the vehicle will suddenly stop charging. When it stops, it appears to be surging an electrical charge back into the home (black marks on outlets requiring an electrician to replace, black marks on the charger plug, and most recently, threw a breaker on our home electrical panel). This is a fire hazard.

The Integrated Charging Control Unit (ICCU) failed - the car is no longer capable of driving due to the lack of ability to charge the battery. I was able to get it to the repair center. The ICCU on this model can fail in multiple ways, which includes the vehicle becoming inoperable at highway speeds. The issue first started 2025/11/13. I tried multiple charging units. It flipped the breaker on my home charger and caused issues for a public charger.

On numerous occasions starting May 2024 and continuing through July 2025, my 2022 Hyundai Ioniq 5 displayed a “Check electric vehicle system” error upon starting the vehicle. In June 2024, Hyundai replaced the vehicle's VCM under warranty. In December 2024, the car wouldn't start. Hyundai replaced the 12v battery under warranty. In April 2025, the vehicle would not drive above 20 mph and warned of imminent shutdown while driving and Hyundai eventually replaced the ICCU under warranty. And in July 2025, Hyundai replaced the charging port under warranty. In all, the vehicle has been out service for 95 days while being repaired under warranty and most of those days I was not provided with a loaner vehicle. During the ICCU replacement, I was forced to rent a vehicle two separate times to get to work. Hyundai assured me that I would be reimbursed both for costs associated with the rental vehicles and the loss of use of my vehicle while under repairs, however despite multiple emails and conversations and having provided all requested documentation, I have received no reimbursement from Hyundai. Please assist me in obtaining reimbursement from Hyundai as soon as possible. Thank you!

On January 31, 2025, my 2022 Hyundai Ioniq 5 experienced a failure with its ICCU resulting in the vehicle to lose all power and become unable to be turned on exposing myself and others to conditions where the vehicle could become a serious safety hazard due to its complete lack of power. This occurred despite the application of the NHTSA Hyundai Recall 272 only two weeks prior to this incident which was supposed to prevent this serious safety defect from occurring. The vehicle's 12 V battery was subsequently replaced allowing the vehicle to display a "Check electric vehicle system" warning. The dealership has since confirmed this as the ICCU defect. No warnings or other messages preceded this incident.

ICCU and High Voltage Fuse blew suddenly and without warning on a 50 mph poorly lit road before sunrise. Vehicle immediately entered limp mode in traffic. Car could not make it safely back home before losing all power in the middle of the road (no warning was given that limp mode was about to fail it just stopped with all screens still on).The dead 12v battery (which the ICCU failed to recharge) made the car completely immobile once it turned off even for towing purposes. Put my safety as a driver and those on the road with me at risk with the vehicle drastically slowing down in the middle of travel with no way for others to pass me. Problem confirmed as the ICCU failure by dealer after finally restoring enough power to get the vehicle in neutral to be towed. The pending recall on this Vin is only pending because it is still sitting waiting for the replacement part a month later. no ETA on a resolution as Hyundai has stopped responding to requests for any information on timelines other than "eventually it will be replaced". All previous recalls for this problem were completed but were only software updates to "potential lower chances of occurrence". Issue is a very known Hardware issue and is very well documented online and local dealers are extremely familiar with it, but Hyundais solution is only to check if the part has already failed and a software update that does not fully prevent the failure in the future. Issue still occurred. no prior warning or behaviors were given

On [XXX] I was preparing to leave for work in the morning. I unplugged my Ioniq 5 from the home charger, entered the car, and started the vehicle. Immediately, the panel warning system stated “Check Electrical System.” Because I am familiar with the warnings that have been displayed related to ICCU failure, I called the dealership to schedule a service appointment (set for February 18, the following Tuesday). I drove the car to work for a meeting, then restarted the vehicle following the meeting and the same message appeared on the screen. I then drove the vehicle directly to Werner Hyundai Service Department in Tallahassee, Florida and left it for diagnostics. On February 14, 2025, my service advisor called to advise that the ICCU and the VCMS had failed and required replacement. I was then advised that I would be placed on a waiting list for an ICCU part that was expected to be released nationwide on March 1, 2025. As of today’s date, March 8th, I have not been made aware of an ICCU part availability (apparently the VCMS has arrived at the dealership and is being held pending the receipt of an ICCU) nor an anticipated repair of my vehicle, it remains at the dealership service department pending parts availability. My husband unplugged our home charger that uses a 220 volt plug and noted that the plug showed melting damage and that the plug and wall had black marks that suggest that the car caused a malfunction that resulted in a spark in our garage. Due to the location of the outlet, the spark did not cause a fire. Since that date, every time our HVAC system comes on at home, our lights flash, this did not happen prior to [XXX]. We are contacting an electrician to inspect the outlet and any affect the surge had on our home electrical panel.

The ICCU (Integrated Charge Control Unit) failed. The car was in a Hyundai dealer repair shop on November 18, 2025, for an unrelated regular maintenance procedure when (i) the technician noticed a logged ICCU error code generated sometime prior to the shop visit and (ii) after the technician cleared that prior error a second new ICCU error code was generated. The shop replaced the defective ICCU. This car had been serviced on prior occasions to install updated ICCU software, most recently as part of NHTSA's recall 24V868000 of November 18, 2024 (also known as Hyundai Safety Recall 272), intended to eliminate such ICCU failures. Installation of that software as the remedy for recall 24V868000 clearly did not prevent the very ICCU failure it was intended to guard against. Please note also that it is common knowledge (as disseminated on various Ioniq 5 forums and Reddit groups) that large numbers of later Ioniq 5 vehicles with newer VINs not included in recall 24V868000, i.e., from model year 2025 onward, have also suffered from these failures despite being initially placed into service with the updated ICCU software, as well as many other pre-2025 remedied vehicles. The Hyundai ICCU software currently in operation on both remedied cars from recall 24V868000 as well as newer cars not subject to that recall is clearly entirely ineffective as a solution to this very serious safety issue. I strongly urge NHTSA to (i) declare the existing ICCU software to be an ineffective remedy for recall 24V868000, (ii) include all Hyundai Ioniq 5 cars for all model years, whether running current ICCU software or not, to be part of the group of unremedied and unsafe vehicles, and (iii) extend recall 24V868000 until such time as Hyundai can actually demonstrate that an effective remedy exists and is being made available to all Ioniq 5 vehicles.

Carr went into limp mode and wouldn’t drive more than approximately 10 mph in traffic. Once I was able to pull over and reset the ignition button, the car seems to be operating normally.

The Integrated Charging Control Unit (ICCU) in my 2022 Hyundai Ioniq has not been diagnosed or repaired despite being at the dealership for 3 months for a safety recall. The ICCU controls the vehicle’s electrical and charging systems, and a malfunction could prevent the vehicle from charging or operating properly, creating a risk of loss of propulsion while driving. Two different Hyundai dealers have had the vehicle since July 11, 2025, but no diagnosis or repair has been completed. I have escalated the issue to Hyundai Corporate, but there has been no resolution or communication of a timeline. The vehicle is available for inspection upon request. No warning lamps or messages were reported prior to the dealer receiving the vehicle, as the car was delivered specifically for the recall repair. Due to this unresolved recall, I have been without my vehicle for 3 months, which has caused significant hardship and forced me to rent a vehicle temporarily. I was given a loaner vehicle eventually but this vehicle is not comparable to my ioniq5. Both dealer's gave excuses for the lack of diagnosing and repairs, ranging from "technician is on jurty duty" or "the climate is too hot outside to look at it."

Vehicle Information: Year/Make/Model: 2022 Hyundai Ioniq 5 SE AWD VIN: [XXX] Mileage at issue onset: ~18,000–22,000 miles Purchase date: April 2022 Ownership type: Purchased new, paid in full Component Affected: Electrical System → Integrated Charging Control Unit (ICCU) / Charging System Problem Description: I am reporting a persistent and unresolved charging system failure involving the ICCU (Integrated Charging Control Unit) in my 2022 Hyundai Ioniq 5. This defect has rendered the vehicle unreliable and currently inoperable, leaving me without safe transportation for myself and my infant child. Over the past year, I’ve brought the vehicle to the dealership more than 10 times, including 6 visits in just the last 3 months, due to charging issues that were supposed to be addressed via multiple recall campaigns (e.g., Campaigns 228, 997, 9A1, 9B5, 272, TCP). Despite these attempted software and firmware updates, the issue persists and culminated in a total failure to charge in March 2025. The dealership confirmed ICCU failure again, but advised that the part is on indefinite backorder, with no timeline for repair or safe operation. This defect is dangerous, particularly as it can result in loss of power and stranding, with potential risks to driver and passenger safety. Hyundai is aware of this widespread issue among Ioniq 5 owners but has not issued a permanent fix or offered viable alternatives to affected consumers. Hyundai denied my Lemon Law claim despite substantial repair documentation and admitted ICCU defects. I have filed with the BBB Auto Line and IL Attorney General. I’m now preparing for legal action. This is not just a consumer issue — it’s a national electric vehicle safety issue involving Hyundai’s inability to resolve a known, system-wide defect in a core safety component. Attachments: Available upon request: repair invoices, dealer assessments, Hyundai’s denial letter, lemon law filings.

Electric Drive System Inoperable, sustained an immediate failure upon engaging in Drive mode. Dashboard lit up with warning lights and messages. Luckily was just pulling out onto road when vehicle completely died. Tow service unable to start vehicle with jumper module. After being towed to dealer, was diagnosed with failed ICCU. The original ICCU was replaced previously in January 2025. Luckily was not underway on the road when it happened. There was no warning, no indication that there was any problem.
Nov 28, 2025
Even after the recall service performed, the ICCU still failed 10 months later. DTC P1E011C is listed and will not charge. This is the same issue for the KIA EV9 and a TSB needs to be issued the same as the TSB 339 KIA did for the EV9.

Despite being up-to-date on recalls for this vehicle intended to address failures with the integrated charging control unit (ICCU), I still experienced an ICCU failure. I was driving along a surface road at approximately 40 mph for about 9 minutes when I heard a pop that sounded like cargo shifting in the rear cargo area. The vehicle then flashed a "Check EV System" warning but otherwise continued to operate normally. About 2 minutes later, there was a warning to stop vehicle and check power supply. After I pulled into a parking lot, I restarted the vehicle, but the errors persisted. I had the vehicle towed to the dealer, where it was diagnosed as an ICCU failure. The vehicle was last charged ~15 hours before the failure on a level 2 charger at a peak rate of 6 kw. The vehicle was driven for about an hour after charging, sat overnight, before being driven when the failure occurred. The vehicle is primarily charged using level 1 and 2 charging, typically not exceeding 6.3 kw. Only a handful of times has level 2 charging rates exceeded 6.3 kw. The vehicle previously had the ICCU fail and replaced in 2023. The car is still at the dealership with no repair timeline.

ICCU failure. Vehicle abruptly reduced speed while on the road. Hyundai has inspected the vehicle and confirmed the failure. "Stop vehicle and check power supply" warning. "Check electric vehicle system" warning. "12v batter voltage low. Stop safely" warning. All first appeared within a few minutes of the vehicle losing power. Vehicle has been at dealership for repair/replacement of ICCU since February 7th.

This is the second time I’ve taken my Hyundai IONIQ 5 in to Hyundai as part of a recall “fix” for ICCU Failure. Each time, the car has been operating fine, I take the car in for the “fix” as it’s required, and then shortly after the car breaks down while it’s in motion / operating. I’ve concluded these are not “fixes” and I have no ability to trust the safety or reliability of the vehicle. 1) ICCU Failure 8 Days After Recall “Fix”. Same thing happened the previous year. Took the car in for the recall “Fix” and shortly after the car dangerous broke down while driving. 2) Car became a brick. 3) Yes, Hyundai Service Center has confirmed ICCU fault. 4) Yes, see #3 5) Yes, minutes before the car became inoperable.

Battery conditioning (heating) is required for fast charging at cold temperatures. The current method of enabling this function takes many steps including going into the EV setting to enable this option (since it automatically turns off when changing some settings in the Hyundai Bluelink App), then opening the navigation screen, looking at a map and scrolling though a long list of charging sites, picking the desired charger then starting the navigation and route to that site. This has to be to done while in route to a specific charger, normally this would be on the freeway 20-40 minutes before arrival at a fast charging station. It is a distraction while driving and is an issue with all Ioniq 5's sold from 2022-2024. Hyundai fixed this problem for the 2025 model year but have not do so on the previous cars at this time. Hyundai needs to add this 1 touch preconditioning option for safety and driver ease of use. I feel it should required on all EVs that offer battery conditioning. I have told them about this several times and not gotten a response and according to posts in various online communities many other have also reported this issue to Hyundai but they have taken no action.

Driving on the highway the car entered limp mode allowing only 30 mph. Messages "stop vehicle and check power supply" with 12V battery indicator. Classic ICCU failure.
Dec 31, 2024
The ICCU broke and the associated fuse blew. The car would only go about 25 mph. It told me to stop driving. The car was taken to the dealer for ICCU and fuse replacement. It said check electric vehicle system, then stop vehicle and check power supply.
Apr 03, 2024
Charge port on vehicle overheats when charging on AC charger and stops charging. Anything above 32 amps. The car is supposed to handle 48 amps.
Jul 31, 2023
When starting the vehicle I received an error that said "Check Electric Vehicle System". The vehicle seemed to be working fine at slow speeds in the parking lot at work. When I exited onto a city street I realized I had lost normal acceleration and could not go above 25mph. I pulled into a parking lot and turned the car off and on to see if the error cleared. It did not. Also received an additional error stating " Stop vehicle and check power supply". At that point I called roadside assistance for a tow. The vehicle is now at my local Hyundai dealership. Their service dept has stated they will take a look at it in 7-10 days most likely.

I plugged the car into our Juicebox charger and waited for the car to say “charging scheduled” before I walked away. My husband didn’t realize I plugged in and managed to back out of the garage, ripping the charger from the car. We need to buy a new charger now. We understand the car should never move if the charger is connected.

Leaving an appt and the car gave a battery ! Warning. While is was looking for a place to pull over the Stop Check Vehicle Electric System. I pulled into a parking lot when the Turtle came up and I was barely able to back into a space. The car was dead within 10 mins of leaving until I parked. I commute daily on an interstate and that would not have given me much time to pull of the interstate to a safe location. Longer warning is needed. Dealer has the car and confirmed it is the ICCU unit and no eta on the part. Yet they are selling 2025 Ionic 5.
Apr 22, 2025
Drove less than one mile and the car suddenly dropped from 45 mph to 20 and would not accelerate (I was almost rear ended by a bus). I was able to pull off the road and the battery died.
Dec 18, 2024
Car has suddenly lost power three times while driving at low speeds or while stopped (eg at a stop light). I have turned off the power (EV start button) and then turned it back on, and the car restarts and starts moving again. The sudden loss of power seems dangerous-- I am concerned that if someone is following close behind me, they will be unable to brake and I will be rear-ended. Please note that I purchased this vehicle used and the problem started occurring the 2nd day I drove the car. (The car was bought back by a dealer in FL under the state lemon law and was subsequently purchased by a dealer in NJ, from whom I purchased the car.) I suspect the same problem was occurring when the vehicle was bought back by the Fl dealer, and it was not properly fixed.
Aug 15, 2024
Highway speed vibration of entire vehicle, particularly steering wheel and seats. This continues despite wheel balance, forced wheel balance and replacing all 4 tires. Multiple trips to dealer without improvement. Test drive of a new, same model vehicle with same or more road vibration at high speed. Numerous same complaints on internet forums.

I am submitting an update to my existing complaint regarding the ICCU safety recall on my 2022 Hyundai Ioniq 5. Since my original submission, my vehicle has been at authorized Hyundai dealerships since July 2025 and remained undiagnosed and unrepaired for over three months. During this time, I received inconsistent and misleading information from both Hyundai corporate and the dealerships regarding the status of the recall repair, as documented via emails, texts, and recorded calls. On 10/31/2025, the dealership informed me that the issue may involve a floor harness/wiring problem and it is out of warranty; however, this appears related to the ICCU safety recall, and Hyundai has not provided a firm timeline for repair. Hyundai’s delay has caused significant inconvenience, as I have been without my vehicle while continuing to make car payments and insurance payments, and arranging temporary transportation. Additionally, Hyundai and the dealerships provided multiple assurances that the vehicle was being diagnosed and repaired, which were later contradicted, reflecting misleading and deceptive practices. I request that NHTSA consider this update as part of my ongoing complaint and investigate Hyundai’s failure to provide timely and adequate recall service, as well as the misinformation surrounding this safety recall.

The vehicle has had 2 12V battery replacements and 2 ICCU failures in about 20 months and just 12,000 miles of ownership with over 100 combined days out of service for repairs.

On [XXX], I was driving my 2022 Hyundai Ioniq 5 SEL when all of a sudden the car started beeping and displaying a 12V battery voltage low. Stop safely message. I was traveling on [XXX] in the Las Vegas area and the car all of a sudden came shut off seconds later. This presented a very dangerous situation with other vehicles traveling at 65+ mph and the vehicle shutting off. I was able to use a portable power jump starting pack to at least get the car restarted and pulled off the side of the highway. Even after jump starting the vehicle, it would only stay running for a minute before shutting off again. The is the second time in 2 months that my car has lost power. The dealer, ABC Hyundai in Las Vegas did a ICCU recall and said that would solve the problems. The problem has not been resolved and I do not feel this is a safe vehicle to drive.

Ok.... So, if anyone reads about Hyundai Electric line.... Ionic series... they would know that since Day 1, Hyundai has had problems with their electrical system. It 1st started with the system never charged the onboard standard 12V battery. I had to purchase Jumpstart boxes, I couldn't run my car ever on acc bc since day 1, my car has never been charging the onboard 12v battery. This caused me to not be able to start my car on more than 5 occasions. I had to ask strangers for help at times, locked out of my car on the side of the street, in parking lots, driving to Auto Zone after a complete trickle charge didn't work bc battery is so drained. During this drive, my cars safety features wouldn't work correctly, everything blinking and i had to make it to Auto Zone to have to buy a new GSM battery. I feared for my life on that drive. Certainly a safety issue. When I asked Hyundai on numerous occasions, they said there's no way for us to test if the recall fix we did actually is helping the issue. So I had to buy my own DC volt meter. I took that car in 4 times to deal with this issue. Now, after my last visit to Holler Hyundai in Winter Park a few months ago, now my car won't charge at home. I tested it with the 2nd charger. F2 fault code on standard home charger. Red lights on my ChargePoint charger. Car charges fine at DC Supercharger (6 times as expensive). I have told Daytona Hyundai multiple times (General Manager knows me) about how I have taken this in to have this problem fixed on many occasions. The GM said he apologizes, doesn't know why it wasn't fixed, they were unprofessional aside from him making many mistakes. The original dealer i bought it from was a bad experience and I do not trust them at all and would not buy from them ever again. I have video and pics of spiders in my car/roaches, etc. Dealership didn't even respond after I emailed them pics. I have bought and owned over 30 cars. This definately needs attention

What component or system failed or malfunctioned, and is it available for inspection upon request? The ICCU failed. The car won't charge on a level 1, 2, or 3 charger. The failure happened in the middle of a charging session. Since failing when trying to charge the car says "charging unsuccessful". The dealer has had the car for 28 days and won't tell me when it will be fixed. How was your safety or the safety of others put at risk? Yes. My family. Thankfully the failure happened in our garage. If it had of happened when we were away from home we would have been left stranded unable to charge. Also, if the ICCU fails while driving the car loses all power and comes to a stop. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. It has been at the dealer for 28 days Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It has been inspected by the dealer Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, there were no warnings prior. All ICCU related recalls had been performed.

This has happened twice so far. I was driving down the street on the main road and the check evs error came on with a yellow triangle ️ light came on. Suddenly the car slowed down, it was hard to steer but I was able to get it to a neighborhood near the school before it shut down. It scare me to know what would have happened if that was on a freeway. Now, because of the fear I hardly drive the car. The last time this happened was yesterday.

The car will only charge at half of the advertised Level 2 AC charging rate. It advertises it can charge at 48 amps; however, we cannot charge above 24 amps. If we charge above that rate the charging will stop. The issue appears to be well documented in online forums where if the charging port reaches about 100 Degrees C it will fault. There is a TSB they are installing but it just makes it automatically derate to ~24 amps which other than providing 15 minutes of higher power it doesn't at all solve the situation. Hyundai has recently stated that they are aware of the issue and they expect people to live with it and re-adjust their expectations; but it is fair to expect the car to perform as advertised. I also don't think any caveats about charging speed for weather or state of charge would be specific to level 3 charging; I am not aware of another EV in existence that doesn't provide its advertised AC charging level. It pretty clearly appears to be defective hardware. We also have friends who bought their car a month later (July 2023) and they are having the same issue; albeit they can still charge at 32amps. To answer the questions directly. - Charge Port - The cars cannot charge in time advertised making people drive without buffers and could run out of power on trips because they can only charge at half the rate advertised and couldn't charge overnight. - We are getting the TSB that will automatically reduce the charging rate this week. we had to wait over a month for an appointment. - It has not been inspected yet but all they are going to do per the TSB is if we say we have the problem they do the software update. - There are no customer facing error codes. The issue first started in March the first day it was over 70 degrees. We did not have an issue last summer or over the winter. The longest we can charge since then at 40 amps is about 15 minutes. We have never even charged the car at 48 amps which is what it is supposed to be able to do.

I have had all recall updates on the car including a recent one on 10/13/2025. Turned on the heater on the first cold night in Dallas this fall and got the engine warning light. Checked the ODB and code was P1A90(96). I was able to drive it to the dealer with a 40 mph max speed. The funny thing is my ICCU has already been replaced under warranty once like 16 months ago, so it seems the replacement parts aren't much better than the original. Dealer confirmed it is an ICCU failure and I'm now waiting on the part. Hyundai has NOT fixed this ICCU problem even when they replace with a new ICCU. Someone needs to hold them accountable for finding a real fix.

The contact owns a 2022 Hyundai Ioniq 5. The contact stated that the electrical charger was overheating, and the 12-volt battery was draining without warning. The contact stated that while charging the vehicle, the contact heard an explosion. The contact stated while driving 20 MPH, the message "Stop Driving Immediately - Return to Dealer"; the check engine warning light illuminated, and the vehicle experienced a loss of automotive power. The contact stated that on one occasion after turning off the vehicle, the battery remained active for 3 days, causing the battery to become drained. The vehicle was taken to a local dealer where the vehicle was diagnosed and the contact was informed that the water pump, the EV battery, the charge point, the inside batteries, the sensors, the navigation system, were faulty and needed to be replaced. The vehicle was repaired; however, the failure persisted. The manufacturer was notified of the failure. The approximate failure mileage was 65,000.

Even after getting all recalls done my IONIQ5 had an ICCU failure. I feel that latest update which was supposed to fix ICCU issue actually accentuated it. With number of complaints on this car for ICCU failure there should class action law suit on Hyundai

On November 29 2025 my 2022 Hyundai Ioniq 5 with 49000 miles was warming up in the driveway. I heard a pop sound from the back seat like a soda can being opened (or a fuse blowing). Immediately afterwards warning lights appeared on the dash saying "Check Electrical System." The vehicle lost power to accelerate and could not be driven effectively. After a few moments, another error saying "Power is Limited" appeared. This could have happened on the roadway which would have been hazardous to myself and other drivers. The car is scheduled to be diagnosed next week by Simmons Rockwell Hyundai in Elmira, NY. These symptoms are similar to the hundreds of other reports of ICCU failures in this car and similar models. On Sept 10, 2025 the car was previously issued software updates to the ICCU software , which were required under NHTSA Recall Number 24V868000. If this problem is proven to be an ICCU failure, the experience with this car is an example of the 2025 software update failing to prevent the ICCU Failure. I request swift action from the NHTSA to compel Hyundai to implement a permanent fix for my vehicle and all other afflicted models in order to make Americas roadways safe again. Until then, everyone should be extra careful when driving behind a Hyundai Ioniq, 5 because it is at risk of dying and coming to a complete stop at any moment. Hyundai is a large corporation and has the resources and technology to fix this, but they have not done so, despite there being more than 300 complaints to the NHTSA about these cars at the time of this writing.

On Saturday, [XXX], at approximately [XXX], I drove my 2022 Hyundai Ioniq 5 north on [XXX] . The car was operating normally. I stopped at the red light at the corner of [XXX] and noticed a large red circle with a "Check electrical system" warning on the driver's display screen. When the traffic light turned green, I pressed the accelerator pedal, and the car did not move. I looked at the "Park, Neutral, Reverse, Drive" shifter. The "P" was lit up, indicating the car was in "Park." I attempted to switch to "Drive," and the status indicator remained in "P." I then pushed the "EV START STOP" switch to see if I could cycle the vehicle off and then back on to clear the problem. The switch had no effect. [XXX] is a busy four-lane, undivided street near the University of Colorado at Boulder campus. I selected the hazard flashers and called 911 to alert the Boulder Police Department that I was in a car that was immobilized in the middle of the right-hand northbound lane. Cars had to swerve to avoid me. The Police Department dispatched a vehicle that arrived 10 minutes later, pulled up behind me, and put its flashing lights on to alert traffic. While waiting for the tow truck, I received another alert on the driver's display that informed me that the 12-volt battery was nearly completely discharged, and I had 10 minutes of power left. The warning counted the remaining minutes to 0, and the displays shut down. From the first warning message to the shutdown, I could not turn the car system off or shift the car out of the park. The tow company had to put dollies under the rear wheels of the Ioniq 5 and lift the front end off the ground to tow the vehicle, as all four wheels were locked. The car was towed to Crossroads Hyundai in Loveland, Colorado. It had just been serviced to address all the recall issues, including the ICCU software update. The car has approximately 16,000 miles on it. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle lost traction power, failed to respond to presses to the accelerator and coasted to a stop. It gave no indication on the dash that there were any problems. Putting the car in park and then selecting drive again restored traction power and the car responded to pressing of the accelerator pedal. The car was not turned off and back on. During the incident: - The brakes, steering, air conditioning, radio and other electrical equipment continued to operate normally. - The car was configured for "Level 2" regen braking, but during the incident, when all pressure was removed from the accelerator pedal, the car did not "feel" like it slowed as normally did during Level 2 regen when there is no application of the accelerator. - The car was configured for "ECO" mode. The drive mode was switched to Normal and Sport during the incident but it had no effect. - The Power/Charge gauge on the dash neither indicated Power when the accelerator was pressed nor indicated Charge when coasting (as would be expected for Level 2 regen) or when the brake pedal was pressed. Car Information: - The car had about 75% charge and reported about ~260 miles of range. - The manufacturers app has not reported any "DTC" codes. - The car has no open recalls at this time. - Service Campaign 997 was completed August 23rd at dealer. - Service Campaign 9A1 was completed August 23rd at dealer. Additional Information: - A previous event similar to the above described event happened on August 21st where the vehicle lost traction power but gave no indication that anything was wrong. - Reported it to the dealer, but they were unable to find anything wrong or recreate the problem. - They applied the ICCU software update.

While driving at highway speeds, there was a loud pop and the display showed "reduce power mode". We had to improvise a stopping place despite being far from home. There was no warning or issues beforehand. This incident was risky because of the loss of power while on a high speed thoroughfare and limited stopping options. The vehicle required a jump to move onto tow truck to take to dealership, where it has remained for two weeks without an estimate for repair. The symptoms.seem consistent with ICCU failure.

The ICCU in the car failed. It immediately limited the speed of the vehicle to 25mph. There were no warnings, it happened all at once. I had to drive on the shoulder of the interstate to the next exit. Obviously, driving 25 on the shoulder while cars passed me at 65+ was not a safe situation.

In Apr 2024 we had an issue with charging the vehicle at level 1 and level 2 took to dealer and they replaced the ICCU unit. A week later the car was DOA no lights nothing so we had to jump start it. We Took to dealer they did an update , week later DOA again. Took to dealer and found out the MSU part needs to be replaced Back ordered for a month and still at dealer was given a loaner, sound familar cause its occuring over and over. Waiting on repair no ETA.

Vehicle was having issues charging large battery. Would shut off immediately. Today 12v battery died, probably related to ICCU recall performed earlier this month.

I started the car, and saw a "Check Electric Vehicle system" alert on the dashboard, and began driving. I was not far from my home, when I saw several messages saying "Stop Vehicle and Check Power Supply" - and the car began slowing and becoming unresponsive while I was in traffic. With my wife and infant son in the car, and being less than I mile from my home I was able to proceed cautiously and make it there. This is likely a known flaw in the integrated charge control unit of this model, which was subject to a voluntary service bulletin put out by Hyundai. I took care of the recommended service and firmware update in September 2023, but it did not prevent this electrical system failure - the service bulletin should have advised replacement instead of putting my family in danger without any warning.

While driving on the highway on 8/12 at around 4pm, with another passenger, doing approximately 65 MPH I received a "Check Electric Vehicle System" warning on my dashboard. The car showed no prior warnings, no other lights were on. MyHyundai app was also showing no diagnostic issues with the car. The car battery was showing a 77% charge at the time. I swerved on to the shoulder, putting myself in danger as this is a really busy highway. I checked the car and could not find anything wrong. Hyundai had not contacted me regarding any recalls. I decided to keep driving to see if I could make it home to diagnose the issue. I made it another 20 minutes and as I was about to exit the highway at around 60MPH the car completely slowed down to 20MPH suddenly, and I was forced to swerve onto the shoulder once again. The car would not accelerate past 20 MPH. Fearing an accident, I called a tow truck and had the car towed back to my house. There were no warnings lights/signs prior to this event. The car completely slowed down from 60-65MPH to 20MPH in the middle of the highway and I was forced to make an emergency stop putting myself and my passenger at risk. The car was brought to the dealership on 8/14 which is the first time I was alerted that there had been a recall on my car and that the ICCU would need replacement. At no point did Hyundai ever contact me via email, text, call, or mail alerting me there was a recall prior to this scary experience. This is gross negligence on the part of Hyundai, as my vehicle could have been rear ended and caused a major accident on the highway.

The cruise will shut off randomly saying the radar is blocked. When it does this the car decelerates very fast. Which is very dangerous in traffic. I’ve almost been rear ended a few times. It has also just started decelerating very fast when in cruise on highway for no apparent reason with no one in front of me.

On the morning of February 3rd, 2025, while driving, I heard a pop. A few seconds later, as I approached an intersection, a yellow warning appeared that instructed me to "Check the Electric Vehicle System". It minimized to a small caution light. I attempted to continue driving, pulling through the intersection; however, the vehicle had an abrupt loss of power; I was unable to proceed over 20-25 mph. In total no more than 2-3 mins passed from hearing the pop to loss of power. I pulled into a neighborhood, stopped the car, and consulted the owner's manual for direction on the warning light. While parked, and an estimated 8-10 minutes after hearing the first pop, I received a second warning, this time in red. It said "Turn power off immediately. Check power supply." I turned car off/contacted roadside, as advised in my manual, for a tow. After review at the dealership, I was originally told I needed a new 12V that it had died while I was driving. I authorized the replacement, though I also indicated to the service department that if that CAN happen, it really does not make sense AND there should be a different warning indicator for a failed 12v that could be replaced roadside versus instructing for a tow.However, after replacing my 12v the service advisor indicated that the car pulled codes and that the ICCU and its fuse seemed to have failed, which likely caused the damage to the 12v battery. After a few days of testing, my car was cleared for replacement of the failed ICCU by Hyundai's techline on February 10th. The dealer then provided a vehicle for my use while I await repairs. I was told a part could arrive the 18th or the 25th and the repair could take 3-4 days once the parts are received. It is still in shop with no updates. On 2/13/25 I filed a complaint to Hyundai; I have not received a response to date. All recalls for these issues had been performed on my vehicle in November 2024; we can no longer, in good conscience, use this vehicle. It is unsafe.

I have a Hyundai Ioniq 5. I purchased it in July 2022 and have been driving it with no major issues except for a couple recall updates. On Monday, [XXX] I was driving home on the Highway when a warning light came on telling me to check EV Connection, it was an orange message. Then the light and message switched to red and displayed a battery symbol. The message said to stop vehicle and check power supply. My acceleration slowed down and I couldn't go above 25 mph despite attempts to speed up. There were many cars on the road when this happened, and I automatically turned on my emergency blinkers. There was a large 16-wheeler behind me that noted something was wrong and slowed down with his emergency lights blinking as well to support me. I panicked and found the nearest exit to come off the highway and before I could make it to the traffic light, the car shut off unexpectedly and completely stopped with no warning. Attempts to restart the vehicle did not yield positive results. After 2 hours of waiting for a tow truck in the middle of the road blocking traffic and waving people around my car, I was able to tow my vehicle to a dealership in NJ close by my house. As it was evening time, I left it at the dealership service center and dropped keys in drop box. I spent several days on the phone with Hyundai Service Center arguing to get my car checked as they told me that appointments were all booked, despite this being an emergency. I had no idea what was happening, but it was clearly inoperable, and I made that very clear. Finally, today, Thursday, [XXX] they confirmed that diagnostic testing showed ICCU failure. They advised that the part is on back-order, and they issued me a loaner for the time being. I have no idea how long this will take to fix. Luckily, I didn't have an accident, although very well could have with how quickly the issue escalated. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Was driving the vehicle in a local road and felt sudden drop in vehicle speed. Had to press hard the acceleration pedal to avoid any collision from behind. The vehicle could not gain enough speed in a ~45~60mile speed zone and driven ~2miles slowly to work place. The vehicle had to be towed to a local delearship as they suggested. The warning message was 'Stop vehicle and check Power supply' immediately after and changed to 'Check EV System' when started ~1hr later at the time of towing. The local dealership diagnosed it to be needing a new ICCU board, integrated charge control unit, which is in back order for ~2weeks (vehicle is still at dealership). In hindsight (after hearing recent news on ICCU failure of Ioniq5), the vehicle had a related issue in Feb 2023. At that time, the vehicle electrical system got blacked-out in my garage (it didn't respond to any button pressing with completely dark dashboard screen). It was towed to a local dealership since jump jump start could not fix it. They replaced a 12V battery for which local dealership could not give me convencing reason for the dead 12V battery .

Driving the car about at 45mph then I heard a pop sound from the rear of the car. Car displayed warning "Check Electrical Vehicle System." I pull over, shut it off, then restarted it. The "check Electrical Vehicle System" light stills on then an emergency message displayed 'Stop Vehicle and Check Power Supply.' When I tried to drive to a safe place I noticed the car would not drive faster than 25mph. If this would have happened in a highway this could have been a safety issue. Dealership confirmed that the Integrated Charge Circuit Unit (ICCU) needs to be replaced.

Respective headlight turns off when using turn signal stalk. This, imo represents additional risk factors: Loss of visibility in the area of where the turn will be traveling In order to keep the lighting on, the turn signal needs to be off. Thereby not being able to give following traffic warning of my intention to turn. Also, loss of ability to have manufacturers install headlight with ability to move in the the direction of the turn. Thank you.

This vehicle can use regenerative braking to slow fully to a stop. However, using regen to slow sharply does not activate the brake lights unless the accelerator pedal is fully released. This means that you can slow at a significant rate without alerting vehicles behind you that you are slowing. Vehicle should activate brake lights when slowing beyond a specific rate. This has been the case since vehicle delivery (3/28/22) and continues today. Occurs at all speeds.

Brake lights during I-Pedal or 1 Pedal driving modes. When under "I-Pedal" or 1 pedal driving mode brake lights do not engage unless foot is fully off the accelerator pedal. This is concerning as the vehicle can brake rather agressively with no indicition to the drivers behind you. The brake lights should illuminate when a sufficient amount of braking is occuring, not just when the accelerator is fully disengaged.
May 26, 2023
Rear brake lights do not properly come on in certain driving modes (i-pedal). The lights will only turn on if you completely release the accelerator pedal. The problem is, that you can significantly reduce your speed down to a stop without ever fully releasing the accelerator all the way.

While driving, the 'check EV system' light comes on, intermittently what will happen is that when stopped the car will put itself in park, when it is in park I can not get it out of park, thus unable to move forward, it has also happened while reversing (and not stopped). I need to cycle the car on and off a bunch of times in order for it to finally turn back on. This is very dangerous while on the road stopped in a busy intersection and has potential for a crash. I have brought it to a dealer 4 times and they do not know what is wrong and cannot fix it. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Accelerator failed to engage on two occasions. 5/18/2023: First while driving on highway at 70MPH. Car slowed down gradually and I pulled onto shoulder. 5/19/2023: Again the next day driving 35 MPH. Pulled off road onto private driveway. On both occasions I turned car off and back on and it resumed normally. Fortunately no accident or traffic problem. I brought car to the dealer (Country Hyundai Northampton) to be checked and they could not find a problem.

Driving down I95 at 75mph. Heard loud "thunk" and car lost both power and brakes. Warning lights on the dashboard said to check brake system. I was unable to pull onto the shoulder due to construction barricades in place. The car slowed to 10mph and continued until I was able to pull over onto the shoulder. This was very dangerous given the highway traffic speeds, construction zone with limited emergency pull over space, and due to it being night time. Turning it off and on again restored power but it happened 4 more times before I was able to make it to an exit. This seems to be a common issue with this model. I have already performed the ICCU recall that was supposed to address this

This vehicle's brake lights do not come on when using regenerative braking. The regenerative braking can bring this car to a complete stop fairly quickly and the brake lights should come on. Several near misses of people almost rear-ending me, and a few got mad enough that I feared a road rage incident. This after only owning the car for 2 weeks.
May 25, 2023
When my IONIQ5 slowly starts and stops while the brake pedal engages or disengages, a noise, something like "click," comes from the rear passenger wheel house. Then, the brakes feel somewhat slippery. I think this has something to do with a transition between the regen brake and the traditional brake. The noise comes up every time I drive. Sometimes, I feel very unsafe because I am worried that the brake system fails.

The brake lights do not come on when slowing down in i-Pedal mode unless you completely let go of the accelerator, representing a massive safety concern. The drivers behind you do not know you are slowing down even though your deceleration is quite sharp
May 25, 2023
Brake lights do not illuminate in 1 pedal driving unless accelerator pedal is fully released. I often bring the car to a complete stop with the brake lights never illuminating until I'm nearly stopped, around 5 mph or less. I often see people ride up behind me quickly and have to slam on their brakes as they don't realize I'm slowing down so rapidly. This can be repeated at any time. I have not spoken to a dealer or the manufacturer about this, nor has it been inspected by any party. There are no warning lights, this seems to be normal behavior, many others have reported on this issue as well. This has been happening since I got the car.
May 25, 2023
When using the car in "i-Pedal" (one-pedal driving) mode — the highest brake regen setting — the car can come to a complete stop whenever I lift my foot off the accelerator pedal, without touching the brake. While in this mode, when I fully lift my foot off the accelerator, the rear brake lights illuminate as expected, however, I often slowly reduce pressure on the accelerator pedal to come gently to a stop. I've noticed that it's possible (and often the case) that I can decelerate to a full stop without the brake lights illuminating until I fully release the brake pedal (at the very last moment before I stop). This means that I can be slowing down at a pretty significant rate without any indication to the drivers behind. Conversely, when using the automatic cruise control (that keeps the car a set distance from car ahead), the brake lights seem overly active and flash on and off quite frequently, especially when going down hills (even if there is no deceleration and the car seems to be coasting). Both of these anomalies seem to aggravate other drivers following the car for different reasons, since the vehicle's intent isn't being properly communicated. The lack of expected brake lights when decelerating gently via i-Pedal mode seems potentially dangerous. I would recommend that Hyundai tune their software so that the brake lights illuminate automatically past a set threshold of deceleration/regen braking (above what would be expected if the car were simply coasting), but not requiring the driver to fully lift off the pedal, since at that point, the rate of deceleration is already uncomfortably high for typical driving.

I was coasting into a library parking space with my foot off the accelerator. The car accelerated even with my foot on the brake, jumped a curb and was stopped with above ground tree roots. The dashboard should have been lighted up with collision warning indicators and the automatic braking should have engaged. It did none of that. The car was totaled. Nothing was ever checked to see if it was a mechanical error. My insurer totaled the car.

When coming to a stop on a slight incline, the vehicle will come to a full and complete stop and occasionally begin to roll backwards after half a 2nd without changing brake pedal position. If the brake pedal is not push further down, the vehicle will continue to roll backwards. I have tested this on multiple IONIQ 5 models with the same result (2022 and 2023). This could cause a collision if there is another car behind the problem vehicle. No warning lamps. Both vehicles have done this since new. Nothing is wrong with either of the vehicles according to multiple dealers.
Aug 06, 2025
The IONIQ 5, like other electric vehicles, uses regenerative breaking. Regenerative breaking can be set at level 1, 2, 3, or i-pedal mode. This determines the strength in which the car will engage regenerative breaking automatically when the position of the accelerator petal is raised above the current speed. i-pedal mode is full one-pedal driving, allowing the driver to slow to a stop without use of the break pedal at all. At level 2, 3, or i-pedal, the car is capable of decelerating at a significant rate even when the driver is still pressing down on the pedal. For example, if you consider it as a percentage and take "foot off the pedal" as 0%, and "pedal pressed as far as it can go" as 100%, a driver could be traveling at 70 mph on the highway, with the pedal pressed at around 60%. The driver could then lift the pedal to only 30%, and the regenerative breaking would then slow the car to, say, 30 mph. This deceleration can be very strong when set to a high regen level. However, the break lights do not illuminate unless the driver takes their foot completely off of the accelerator. In i-pedal mode especially, it is possible to decelerate from highway speed to a near stop in only a matter of seconds, without the break lights ever activating. Other EV manufacturers illuminate the break lights based on the cars measured deceleration when using regenerative breaking, and do not have this issue. If the driver has driven other EVs in the past and prefers the one pedal driving mode, it is likely they will not even know that their break lights are not illuminating during heavy deceleration, creating a significant danger of being rear ended when driving in heavy traffic.

Interior driver's side door handle broke off. The driver cannot open the door without lowering the window (electrically operated) and reaching outside to pull the exterior door handle. The car must remain of to do this (if off, the window cannot be lowered). I deem this to be extremely dangerous in the event of an accident when the car cannot be started; the driver is stuck in the car.

When the vehicle is parked and the trunk is opened, some percentage of the time the trunk does not remain in the open position and immediately closes. If the trunk is then opened additional times it generally remains opened. When the trunk unexpectedly closes the trunk object detection does not work and applies a great deal of downforce. When the trunk finally stops trying to close it remains in a locked position between open and close, it does not reopen. Mine and others safety is at risk as the trunk can cause bodily injury resulting from the trunk unintended closing. This issue happens around 50% of the time after the trunk is commanded to open. Two dealerships have been unable to reproduce this issue, but neither has tried multiple times, nor have they driven the vehicle to get the error/bug to reoccur. There are no warning or errors that this issue is going to occur. The only warming occurs three seconds after the trunk fully opens, the trunk closing audible rings. This error has persisted since shortly after first purchasing the vehicle.

Hyundai describes the lack on rear window wiper on this hatchback/suv as handled by the 'air wiper' the include air ducts allow for. The problem is that this 'air wiper' only works if it is actually actively raining AND you are driving at highway speeds. At any other time the rear window is almost always dirty and has no way of being cleaned while driving the car. One would need to pull over to a gas station to clean the window if on the road. Not sure you have a resolution section but the resolution would be to require Hyundai to install a rear wiper with wiper fluid mechanism.

- EV Fuse blown My Hyundai Ioniq5 EV electrical system stopped function on March 25th, 9 month after we purchased this EV, on a busy highway. It took Hyundai dealer 8 weeks to fix this issue. Due to the fix report, some fuse was blown. - Automatic Emergency Braking engaged On Jun 16th, when driving on HW 90 west bound, road was clean. No vehicle in front of me. The "Automatic Emergency Braking " was engaged. This could be very dangerous if the highway was busy.

In stop and go traffic on freeway, car was moving at about 5 miles an hour but car kept moving, collision warning and automatic braking did not activate. Had to turn off car and coast to a stop. Nearly collided with vehicle in front
Nov 09, 2023
I parked the car end visited a store. Upon turning the car back on, the car freaked out and indicated that I needed to "Stop vehicle and check brake system." At the same time, the check engine light illuminated and the car entered limp home mode. CEL codes C164286 & C238001 appeared. The next day I brought the car to a Hyundai dealer who "fixed" the issue by removing a component that is unrelated to the braking and security systems and the car became drivable again for ~300 miles. I then went on two business trips and returned home. I drove the car and it again experienced the same error upon turning the car on. The braking system still functioned, but all electronic features were disabled by the car and braking involved a lot of force on the brake pedal to get the car to stop. For as long as I've owned the car, it has (infrequently) flashed the "Check automatic lane change system" when the car is turned on but the error goes away and doesn't return for weeks to months. The car is now back with the dealer who "fixed" the issue originally but their EV tech isn't always there to look at cars, even though the issue is not necessarily EV related as all cars (should) have brakes.

Hyundai Ioniq EV's have a continuing issue with a component called that "ICCU". The ICCU and high voltage fuse failed even after two recalls meant to monitor that problem and update the software. Luckily, mine failed in my driveway at home which did not put me in immediate risk. However, many people have this part fail while driving on roads and highways with zero warning. There have been two ICCU-related recalls that my car has had. When I started my vehicle I heard a "pop" and then the dashboard said "Check vehicle electrical system" and then shows the "limp mode" icon allowing to drive the vehicle at a slow speed to safety.

I am filing this complaint to report a serious safety defect involving my 2022 Hyundai Ioniq 5. The vehicle experienced a sudden failure of the Integrated Charging Control Unit (ICCU), which caused the car to completely shut down and lose power while in motion. My family member, who was driving at the time, stated that the car lost power and shut off without warning on the road, creating an extremely dangerous situation. Thankfully, they were able to pull over without incident, but this type of malfunction could easily result in a collision, injury, or worse. I later discovered that this issue is part of a widespread ICCU failure affecting Hyundai Ioniq 5 and other Hyundai/Kia EVs. My vehicle has been at the dealership for over a month, and Hyundai has informed me that the part required to repair the vehicle is backordered for 2–3 months, leaving me without my primary mode of transportation. This issue is not only a reliability concern but a serious safety hazard that warrants immediate investigation and intervention. A vehicle that completely loses power while driving is unacceptable, especially for a relatively new vehicle under warranty. I urge the NHTSA to investigate the ICCU failures in Hyundai Ioniq 5 vehicles and determine whether a broader mandatory recall is needed due to the loss of motive power and serious safety risk. Many owners are affected, and delays in repair parts are putting consumers in unsafe situations.

While driving on the highway in foggy conditions, the smart cruise control system and forward safety system suddenly shut off while I was going 70 miles an hour. This almost resulted in a car rear ending me due to the sudden deceleration. The following day, with clear weather, the same issue happened again despite nothing appearing to have caused this issue while I was driving. This is a very serious concern to suddenly stop on a highway.

1) This is the second occurrence of this issue within the past 12 months. While driving, my EV displayed various blinking lights and a “Check EV Connection” message, followed by a “12v Battery Critical” warning. The entire system began shutting down in the middle of the road. I managed to pull over before the car completely shut off. 2) This malfunction posed a significant safety risk to me and others. The rapid deceleration and uncertainty of an imminent shutdown almost caused an accident, either from other vehicles crashing into me or from my inability to stop in time, potentially hitting another car. I have faced this life-threatening situation twice within a year due to the same issue. 3) The problem was confirmed by my dealership less than a year ago, and my car is currently being towed back to the dealership for re-inspection of the same issue. 4) The vehicle and its components have not been inspected by the manufacturer, police, insurance representatives, or other parties for the current situation. However, the manufacturer issued a recall for this problem last year AFTER my initial report, incident, and repair. They claimed to have fixed the faulty issue or replaced the necessary parts, when my vehicle was repaired less than 12 months ago. Despite this, I am experiencing the same critical problem again. 5) During the incident, my entire panel started blinking with a “Check EV Connection” message, followed by a red warning sign indicating a 12v Battery Critical Failure warning. The system then went black, and the panel continued to blink white and black consistently while parked. The car cannot be started or moved.

I have not had an electrician come out yet, but after a quick google search it became apparent that others have experienced the same issue and I thought it was important to report.

I was driving 75mph on the freeway and I heard a pop and then the electrical warning system on the car lit up. I lost power to the car and was only able to accelerate minimally. There was a warning of low battery and the vehicle was going to lose power. I turned on my hazard lights and was able to get to the exit and was able to exit the freeway safely. Once the vehicle lost power I was unable to open the charger door, start the vehicle, use any of the key fob functions and had to jump the 12V battery, only to die immediately after. There is no pre-warning to this happening, it just shows the alert and the car loses all power. There are also problems with the vehicle after being plugged in to charge and it says "Charging Unsuccessful", or stops charging after a short period of time. It also will not charge to full capacity at home or the charging station. I receive no warning lights or messages about why the charge is not working. It took weeks to get the vehicle into the dealer, making it extremely unsafe to drive and the error has almost caused a major crash. My vehicle has been at the dealer and has not been diagnosed with any issues yet. The dealer has provided me with a rental vehicle...in which now I'm paying for gas. Reading through these other comments...who knows how long it will be to get my vehicle back, yet I'm still making my payments...this isn't

ICCU stopped charging my auxiliary battery (Hyundai Ioniq 5). I couldn’t figure out why, but I began carrying a portable charger with me which instantly got my car going again. One day during a particularly nasty snow storm, my battery was dead again and I jump started my car. I drove it about 40 feet before I realized it needed snow socks. I stepped out of my car and got back in and a whole myriad of warnings were going on. I got a code for the vent flaps (snow had got stuck in there…that was an easy fix. Also my Auto Hold light, Check ABS light, and Smart Cruise Control warning indicator lights were all on and are still two months later still not working. The car otherwise operates well enough to drive as I replaced the auxiliary battery. Since replacing the battery, the car operates as well as the ICCU (it charges the new battery) but the previous issues remain.

My vehicle was fully charged. About 1 mile after leaving my house, I received a warning message on my display (vehicle electrical system error or similar). Shortly after I received another message that power was reduced, then finally, "stop driving". I pulled into the nearest driveway and called roadside assistance. At that point, the vehicle was COMPLETELY dead. No lights or power whatsoever. I could not activate the car to shift into neutral. I had my vehicle towed to the dealership. They said it was due to a faulty ICCU and fuse. After about a week they were able to replace the ICCU, fuse and update the software.

The Draw-tite 76589 was purchased through Uhaul Canada for my 2022 Ioniq5. After a few months of use with a light trailer according to the specifications of Hyundai, Uhaul and Drawtite, it tore of a part of the vehicles frame. After the inspection at U-Haul and Hyundai dealership, they concluded that the problem occured because the hitch wasn't designed to mount on the specified by Hyundai mounting spot, hence it caused the damage. There are many cases like that on Ioniq5 forum as well as at different hitch installing companies who used this model. This model is now discontinued, although still sold, and was replaced by a 76632 model which mounts to the right location. Horizon Global did not contact the customers, not their distributors/dealers and doesn't compensate the customers who contacted them. After 7 months I still have the hitch on the car if you want to inspect it.

When driving for a distance at higher speeds, power will suddenly drop to the zero point btw acceleration and regeneration. You can feel the car start to drag as the power drops. If you press hard on the accelerator to stop it from slowing, it will suddenly jump forward. This has happened now on several long trips where I am constatly fighting with the car to keep it powered and not slipping into the zero zone. When it leaps forward the lane assist will also grab control and make it difficult to control the car. The car also stops slowing consistently when I take my foot off the accelerator and will move/ jump forward more than is typical for an EV instead of slowing the way an EV should as it regenerates. This all happened twice previously on a long trip and today constantly during a three hour drive. Does not feel safe!

1.We purchased the vehicle (Hyundai Ioniq 5, 2022 Model) on MAY 20, 2022. 2.The vehicle was acceptable until it started to fail on us while we were on the road, and soon after the vehicle crawled home at limited power and came to a stop, it would no longer even turn on. 3.Then started our nightmare with Hyundai USA. We called the service department and they told us, based on our brief description of what happened, that our vehicle would be unsafe to drive a single more mile (which was impossible anyhow because it wouldn’t turn on), and to tow our vehicle to Hyundai dealership in Fayetteville, AR for repair on DECEMBER 27, 2022 at our own expense. 4. From what Hyundai, Fayetteville, AR's service engineer named Evan told us, they have replaced the fuse no less than four times and it kept blowing when they went to test the vehicle. After the basic fuse replacement, it caused the problem to become worse, and revealed an ICCU problem, that then revealed acceleration and charging problems, and the initial fuse problem still persisted. Codes kept popping up, and whenever they fixed the current issue, another one would present. Long story short, it turned out the vehicle was experiencing “mass power surges,” issues with the batteries, and displaying codes for reasons they were unsure of, causing the basic fuse replacement to “pop.” They even called in a Hyundai Engineer directly from corporate to try to fix the vehicle, but according to Evan, even he had no idea what was wrong with the vehicle and had left with some data.

Hyundai's connected car service (bluelink) suffered an outage that resulted in driver profiles on many Hyundai vehicles being deleted/reset. No notice was provided and the profiles were not recovered. As a result, the vehicles did not funtion as expected. Driver assist settings were set to default (steering, braking, and acceleration functions included). Hyundai provided instructions on how to set up a new profile in response rather than restoring the customer data to their personally owned hardware (car).

This is an electric vehicle that features “iPedal” driving, what Hyundai refers to as one-pedal driving. The main safety issue is that when you decelerate using one pedal, which is a fairly aggressive deceleration, the brake lights do not come on unless you lift your foot entirely from the accelerator or apply the brake pedal (which one would rarely do in iPedal mode). Hyundai needs to rethink their concept of operations for how their brake lights should operate. People are at risk of getting rear-ended. I didn’t realize this was how the vehicle operated until I was almost rear-ended today. Please push them to fix this issue.

I was driving to the dealership due to an unusual message. I was on a main street less than 2 minutes from home when an alert came on the screen that said "critical 12v system" I believe. The screen went off shortly after so I was unable to fully capture it. Within 20' the car stopped itself on the road and shut off. All systems were offline with a total power loss. I could not turn my hazards on, the wheels were locked and I was unable to move the car. I had to stand outside my car to alert oncoming traffic to avoid me. Had I been on the highway when this happened I feel it could have turned deadly quickly, and would have been far worse at night It has been confirmed that the ICCU and high voltage fuse had failed. There are many other owners online speaking of the same problem. The error prior to this reported in the car was "check electric vehicle system." No extended details available, and the online app that shows car codes said "all systems normal" and still does even though the car is entirely dead.

Windshields in the vehicle keep breaking with little to no reason. In 6 months of ownership we have fully replaced 3 windshields. Windshields provide a line of protection for the driver and passengers when the vehicle is being operated. Continuous breaking of a windshield indicates a bigger safety issue with the manufacturing of the car/glass. In one instance there was an audible screeching sound and the glass suddenly cracked for no reason.

The ioniq 5 has a one pedal driving mode, where the car will come to a complete stop without needing to press the brake pedal, similar to other EV's. In this mode, the gas pedal operates differently then in a conventional car - pressing the pedal approximately 1/3 of the way down represents neutral, where the car coasts. Pressing the pedal less then that - between 1/3 and not pressing it at all, applies braking power to the car, either through regenerative braking or the application of the physical brakes. The issue is, the brake lights on the rear of the vehicle do not light up when the gas pedal is depressed any amount. If you press the gas pedal as lightly as possible, the car will brake a fair amount but there is no warning to driver's behind that you are decelerating. I have twice been almost rear-ended, both times while slowing down in one pedal mode. I suspect the lack of brake lights until you take your foot fully off the gas pedal is a contributing factor. Other Ioniq 5 users have experienced the same issue.

On February 6, 2023 at approximately 9:50 a.m. I was driving my Hyundai Ioniq 5 SEL northbound on CA Highway 135, Santa Maria, when I heard a loud pop coming from my car. Within a few seconds my car lost speed rapidly, from 55 mph to 25 then a second later 22 mph . I tried to accelerate - there was no response - the car maintained the 22 mph. A message appeared on the right side of the dash board in an orange circle “check vehicle system” with a small upside down triangle with letters EV also inside this circle and a “small orange battery” picture showed on the left. I drove the car onto the shoulder of the road and with my hazard lights blinking, drove a half block making a right hand turn onto Miller Street to get off the Highway. I entered CHC Medical Building’s parking lot. Immediately upon entering the parking lot, my car stopped dead, before I had a chance to pull into a parking space. My car was now blocking cars coming in and out of the parking lot. I called Roadside Assistance and reported the above, the time was approximately 10:19 a.m. A tow truck (AAA) was requested by Roadside Assistance. After my conversation with Roadside Assistance, I turned the car on again and got power briefly - I moved the car into a stall space and waited. My car arrived at the Hyundai SLO dealership shortly before noon. The ICCU and fuse failed, and replacements have been ordered but the ETA is unknown Abrupt loss of speed was very unsafe
