ELECTRICAL SYSTEM

138 complaints

Vehicle experienced sudden loss of propulsion while driving despite indicated remaining battery charge (~13%). Vehicle became immobilized and required towing. Dealer performed static diagnostics after recharging and found no stored fault codes, but no testing was performed to evaluate sudden loss-of-propulsion under load. Manufacturer closed case without investigation. This presents an ongoing safety risk of unexpected propulsion loss in traffic.

Car died due to 12v battery failure due to ICCU not working properly in Oct 2023. Did ICCU recall and safety updates with dealer and they installed a new 12v battery. Oct 2025, car dies again due to 12v battery failure to to ICCU. Car has been at dealer for over 2 months waiting for new ICCU part to arrive and be installed. The ICCU system on this vehicle and related vehicles in the Hyundai/Kia line up seem to have a significant design flaw. I have no confidence a new ICCU part will 'fix' the issue. This will just push the issue out again until the new 12v battery dies and we do it all over again.

Unable to do AC charging due to faulty ICCU. A failing ICCU is dangerous to drive as the car may lose all of its power

Jan 29, 2026

I first noticed something was wrong when the car only charged to 90% even though I set it to 100%, since I wanted it ready for the storm. I drove normally after that. When I tried to charge again, the breaker tripped. L1 charging also tripped the breaker. V2L didn’t work either. The weird part: the orange light was still on, and it was still charging the 12V battery multiple times. I have a battery monitor and everything looked normal. I was also able to drive the car to the dealer with no issues at all. No warning lights or errors on the dashboard. Dealer diagnosed it as an ICCU failure. Part is on backorder with no ETA

While driving vehicle it flashed warning to check battery and power was severely reduced, limited to about 25 mph. Battery and EV warning triangle appeared. Then within less then a minute it brought up additional warning to "Stop Vehicle and Check Power Supply" and power was further reduced to less than 10-15 mph. Car now also displayed turtle icon. After safely getting to parking spot vehicle began to shut off critical systems or displays intermittently before eventually fully shutting itself off.

Iccu failure unable to charge or drive

Jan 19, 2026

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.

While driving, a warning message displayed on the dashboard stating that there was a fault in the electrical system and that I should pull over and stop the car. As I tried to find a safe place to pull over the car lost power and I pulled onto the shoulder. The shoulder was only as wide as the car. I was stopped on the side of a two lane road with a 55 mph speed limit. In order to exit the car I had to step into the travel lane. The electrical fault resulted in no power available to the warning flasher lights or headlights. This occurred at night with no street lighting to show oncoming drivers that there was a stopped vehicle immediately next to the traffic lane. This put me and other drivers at risk. The vehicle was towed to a dealer capable of working on this type of failure. The dealer determined that the failed component is known as the ICCU. This is a critical part and had been known to fail in this model. My vehicle had already received every software update in an attempt by the manufacturer to avoid the ICCU failure. The dealer replaced the failed ICCU with a new working ICCU. It is my understanding that the replacement ICCU is identical to the failed ICCU and a risk remains that the new one could fail as well with a loss of power while driving at speed.

Check Vehicle Electric System warming shows up on dashboard, then vehicles enters turtle mode and then cuts power shortly with violent jerking of the vehicle. Shortly after, all system shuts down, 12V is said to be weak and car cannot move.

Nov 30, 2025

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.

Nov 13, 2025

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."

My 2022 Hyundai Ioniq 5 has experienced two ICCU (Integrated Charging Control Unit) failures, both completely immobilizing the vehicle. •First failure: November 2024 •Second failure: December 31, 2025 (confirmed by dealer 1/13/26) •Downtime: Over 45 days total •All recall work and maintenance were performed at the same Hyundai dealer, under active warranty, but the recall did not prevent the second failure. Safety Risk: These ICCU failures cause sudden loss of propulsion, leaving the vehicle stranded and creating a serious safety hazard. The second failure after recall indicates the repair is inadequate. Luckily mine failed at home before departing for an errand, but I am gravely concerned about others not as fortunate or for myself should the issue recur while I am traveling on a public road. Examples of this are reported online in a variety of forums. Widespread Issue: Thousands of owners report similar ICCU failures, often after recall repairs, on forums and social media. There is also ongoing Canadian litigation addressing the same defect. Requested Action: •Investigate repeated ICCU failures in Hyundai/Kia EVs •Evaluate the adequacy of recall repairs •Require Hyundai to implement a permanent fix •Take appropriate safety action to protect vehicle owners

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.

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.

The ICCU has failed. This component was replaced approximately one year ago as part of a recall, but it has failed again. The vehicle is currently parked and cannot be driven until Hyundai provides a replacement part, which may take up to three months. The failure presents a safety concern, as the vehicle can shut off while driving and leave the driver stranded. The Hyundai dealership has confirmed that the replacement part provided by Hyundai—the ICCU—is the component that failed. There were no prior warning signs of failure, other than the vehicle refusing to charge on a Level 2 charger.

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.

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.

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.

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.

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.

After pre warming the car in the garage, I left for work. Three minutes into the drive I heard a single popping sound from the passenger side rear of the car.

This is an EV vehicle. This is a recurrent problem with the Ioniq 5 and is all over the internet. For me this is the 2nd electrical failure. The first time the accessory batter failed and the ICCU controller failed and had to be replaced. Now its at the shop for the 2nd time for the same failure. Not sure if its the ICCU again or not. In and of itself not a problem to send it off to fix, The major issue is how it fails. There is no warning, If you are on the highway going 70 mph it goes flat... no propulsion. This gives you no or little power to get to a secure spot. It then is only capable of about 20 mph. This is dangerous as hell. The first time it died completely and wouldn't move. For myself, i was lucky i was on a local road. I was driving. For my wife, who drives this car it would be harrowing. This is a recurring problem with this vehicle. A solution has not been found other than to swap parts. Hyundai need to be put on notice for a permanent fix.

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.

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.

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.

May 29, 2024

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

The ICCU failed in the car. The car lost power while driving and showed an EV warning and the 12V battery warning.

Aug 24, 2023

Hyundai San Jose dealership, Customer Service, told me, The fuse surrounding the Lithium battery is broken. This causes the whole car break down, and it is very dangerous to drive. My car has been in this Hyundai dealership over 5 months now, Hyundai cannot send the parts to San Jose Hyundai and I cannot drive the car. Also the 12V small lead acid battery in the front, broken down a few times. Cannot start the car. The whole car shuts down.

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.

Feb 23, 2025

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 .

Jun 23, 2023

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.

May 26, 2023

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.

I am writing to report a serious safety incident involving my 2022 Hyundai Ioniq 5 and to request a thorough investigation and guidance on next steps. On Jan. 3, 2026, at approximately 6:15 p.m. on a snowy day, we parked our car in the driveway of a weekend rental home near Lake Tahoe, CA. The driveway had a slight slope toward the house, and we backed the car down the driveway with the rear of the car facing the house. My husband turned off the car, then all five occupants exited the vehicle, closed the doors, and began unloading items from the trunk. The car began rolling backwards toward us and the house. It only stopped after pinning my husband into a snowbank created by a snowplow. The other three adults and our [XXX] niece narrowly avoided being struck. While pinned behind the vehicle, my husband had to dig out some snow to reach into his pants pocket and retrieve the key fob. I then moved the car forward a few feet to free him. Although he was pinned in the snow, my husband was (thankfully) not seriously injured. After freeing my husband, I put the car in Park and turned it off. In this model, the parking brake engages automatically; there is no separate parking brake button or lever. A few minutes later, without anyone in or near the vehicle, the car again rolled backwards down the driveway into the same snowbank. Tracks in the snow clearly indicate that the wheels rotated and the car rolled; it was not sliding on ice with the brakes applied. In other words, the parking brake and/or Park mechanism failed to hold the vehicle in place in sub freezing, snowy conditions. The temperature at this location and time was in the mid 20s °F. After returning home from our trip, we took the car to our Hyundai service center, which has performed all maintenance since we purchased it in 2022. The service center performed all standard diagnostics but was unable to replicate the failure conditions. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Jan 22, 2026

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.

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)

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

Feb 15, 2024

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.

After a loud bang (fuse blown) the car was unable to move just before I was about to turn into an intersection. The ICCU failed for the second time, all warranty repair completed prior to the incident, first failure occurred in 2024. Both failures occurred close to a when the lead acid battery failed and needed replacement. When the car was stopped and started again, I was able to drive the car slowly to the dealership located less then 1/4 mile away. The car behaved as if there was no power steering but the car still jerked the wheel around to try to put me back into the driving lane presumably because I was driving in the emergency lane. Failed component was ICCU Module 36400-1XAA0. Vehicle was unsafe because I was unable to move while about to turn into an intersection. After stopping and starting the car, the was drive-able bit mildly erratic when attempting to move the car to a safe location (out of the left turning lane). Problem was identified, confirmed, and repaired by dealer under warranty for second time. Component and vehicle inspected by dealer. Failed part sent back to manufacturer. This incident occurred without any prior warning or indication by the vehicle. There were no active recalls on the vehicle at the time of the incident.

Jan 26, 2026

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.

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.

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.

The component that malfunctioned is the Integrated Charge Control Unit (ICCU) and related high-voltage charging system in my 2022 Hyundai Ioniq 5. The ICCU controls AC (Level 2) charging, DC fast charging functions, and power delivery. The ICCU assembly and charging components were serviced and replaced by an authorized Hyundai dealer and are available for inspection through service records. This defect created a safety risk because the vehicle experienced complete charging failure and reduced-power operation. Loss of charging capability can leave drivers stranded, and reduced-power “turtle mode” conditions can limit acceleration and vehicle performance, creating hazards in traffic. The charge port has also not locked during charging, creating a potential risk of electrical arcing during DC fast charging. The failure was reproduced and confirmed by an authorized Hyundai dealer. In approximately January 2025 the vehicle would not charge and remained at the dealership for an extended period (about January through June 2025). After diagnosis and consultation with Hyundai technical support, the dealer replaced the ICCU assembly and high-voltage fuse. The vehicle and charging system have been inspected multiple times by Hyundai service centers. Hyundai issued recall campaigns in 2023 and 2024 involving ICCU software updates and fuse-related work, but these did not prevent the later failure requiring full ICCU replacement. Prior symptoms included abnormal charging behavior and eventual total loss of AC charging capability during the 2025 failure, making home charging impossible. After the ICCU replacement, the vehicle exhibited unusually loud cooling fan operation during Level 2 charging, documented by the dealer. There were also charging-port safety concerns. After one service visit, an important DC pin cover/cap was not properly installed until corrected on a return visit, leaving charging components exposed.

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.

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.

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.

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!

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.

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.

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.

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.
