2023 KIA EV6 Problems & Complaints

10:00 am January 28th AFTER A DRIVE OF APPROXIMATELY 20 MILES TO THE GROCERY STORE, we parked the 2023 Kia EV6 Wind,in the parking area, then entered the store to shop. On returning, we placed the groceries in the trunk and proceeded to leave for home. The push button "START" provoked a notice on the dash that the 12 volt battery was "LOW". The drive circuits would not enable. Prior to going in the store the dash information reported the main battery was at 62%, all else is normal. We are now stuck 20 miles from home. We called KIA roadside assistance, via a cell phone. The Kia site told us it did not recognize the VIN number we had entered three separate times.. It would not proceed down the logic tree for us to be assisted by their service. We called :AAA"they sent a service truck with a jumper battery which allow us to get a small charge on the 12 volt system, enough to get us home. Immediately upon arriving I opened the hood, retrieved my "Fluke DVM" to measure battery voltage. 6.2 volts was the reading. The 12 volt battery was not charged by the voltage regulation system in our car. Fortunately, we were dressed well, being the temperature outdoors was 14*F at the time and we had access to the grocery store for safety. Yet still a major inconvenience due to breakdown. Later, I disconnected the negative battery terminal, then connected the 12 volt AGM battery charger I have purchased for home use. The battery was charged to full overnight to 13.2 volts. I removed the charger cables, then left the battery set for 12 hours disconnected from the vehicle. The voltage dropped to 12.6 volts dc, indicating a healthy battery. This morning January 29th, I called the Kia dealership to explain our problem, the scheduler has acknowledged a possible bad charge control unit, but told me if it was not a control unit problem, I would pay a fee of $135 dollars for the troubleshooting, even though the vehicle has approximately 33,000 miles. Schedule Feb 4th

The vehicle ICCU failed on 18 January 2026. It previously had the ICCU inspected and updated as part of #24V-867. Warnings on screen told me to stop driving and pull over. Had vehicle towed to Dealer where they confirmed ICCU failure and initially were going to charge nearly $4000 to repair. KIA Customer care spoke to dealership and ICCU repair is now being covered. It seems apparent that the earlier fix did not resolve the issue, and raises concerns over whether KIA truly understands the underlying cause. Will the replacement fail after 30k miles? Will I be stranded?

Without any warning the car dies on the interstate, it warns you once it fails. The ICCU fails. It left me stranded with my dog.

Got a Check electrical system error, car reduced speed and 12v battery stopped charging. Car was towed to the dealership and they confirmed that the ICCU needed to be replaced.

Car said there was a 12V low battery danger and said to pull over immediately while driving. After taking it to the dealership, they said my ICCU went out. So they had to replace it. I've read that the ICCU on these cars are notorious for failing and needing replacement.

While driving my Kia EV6 in the middle of a snowstorm, the vehicle experienced a sudden and severe power failure. I heard a loud popping sound from the rear of the cabin, after which the vehicle immediately entered reduced-power (limp) mode. Within approximately one minute, the vehicle shut down entirely and lost all propulsion and mobility. I was able to move the vehicle to a safe location only because I was not in traffic or on the highway at the time of the failure. Had this occurred at highway speeds or in active traffic, it would likely have resulted in a dangerous situation with a high risk of collision, especially given the severe winter weather, low visibility, and slippery road conditions. The vehicle has approximately 21,000 miles. This is the second failure of the Integrated Charging Control Unit (ICCU) in this vehicle. The vehicle was inspected by an authorized Kia dealer, who has officially diagnosed the failure as a failed ICCU and associated fuse. There were no warning lights or messages prior to the failure. The first indication of a problem was the popping sound, immediately followed by limp mode and then a complete shutdown without further warning. The vehicle is available for inspection upon request. The repeat nature of this failure, lack of advance warning, and sudden loss of propulsion represent a serious safety defect.

While driving at normal speed, my Kia EV6 experienced a sudden and complete failure of the ICCU system with zero warning. The vehicle instantly lost all propulsion power and all 12V electrical power, rendering the car uncontrollable and unsafe. I was unable to accelerate, unable to place the vehicle in gear, and unable to activate hazard lights. This occurred despite the vehicle being at approximately 99% battery charge. This failure created an immediate and severe safety hazard, as the vehicle effectively became a dead object in traffic without warning to surrounding drivers. There was no prior alert, no dashboard warning, and no indication of impending failure. This defect is well-documented and pervasive across the Hyundai–Kia–Genesis E-GMP electric vehicle platform and has persisted despite multiple recalls spanning several model years. Kia has acknowledged the issue through recalls but does not have a reliable or permanent fix. Even newer model year vehicles that are claimed to address the issue have experienced the same failure. If this defect occurred in an internal combustion engine vehicle — for example, a random, complete engine shutdown or fuel system failure while driving — it is highly unlikely that regulators would permit the issue to persist across multiple model years without resolution. The fact that this is occurring in an electric vehicle should not lower the safety standard. A sudden total loss of propulsion and electrical power is equally dangerous regardless of drivetrain. Critically, there is no assurance that this failure will not recur, even after replacement of the ICCU or related components. Owners are effectively being returned vehicles that can lose all power again at any time, without warning. It is deeply concerning that this issue remains unresolved after multiple recalls and multiple model years. Continued operation of these vehicles without a verified, permanent fix places the public at ongoing risk.

While driving, heard a pop and a check electric vehicle system error popped up on the dash. Car was not drivable except for very low speeds shortly after (impacted safety of the drive) until it eventually stopped being able to turn on at all.

The vehicle experienced a total power failure resulting in complete inoperability (no start, no unlock, no electrical response). This is the second occurrence within approximately five weeks. The most recent incident occurred after the vehicle was fully charged and driven the day prior. There were no warning lights or messages before the failure. The vehicle was previously inspected by an authorized dealer and a manufacturer service campaign related to the charging/low-voltage system was performed, after which the problem recurred. This condition can strand the driver without warning and poses a safety concern.

Vehicle does not reliably handle the 12V battery well. Many times, I see it sitting at 12.8 VDC when driving the vehicle. On a ICE vehicle, the charging voltage is close to 14V when running/driving. On 3 separate occasions, when I tried to "start" the EV6, the 12V battery was too dead to allow the car to be started. Basically stranded. This can be life threatening if this occurs in frigid temps. Or a hazard to traffic if/when the car tells you to "pull over safely, immediately". OK, I can "block the box" because my car died??? Kia and Hyundai need to address this issue that's common to their recent "luxury" EVs. With all the high-tech these cars have, why can't it manage the charge-state of the 12V battery? Tesla vehicles do not have this issue (I believe). Tesla EVs do "lose" their 12V battery over time, but that is similar to the 12V battery that eventually dies in a regular ICE vehicle. This 3rd time that this occurred, I called 800-KIA and had the car towed. So far, "they cannot reproduce the problem".

The ICCU in my Kia EV6 failed while driving. Thankfully I was not involved in a crash, but my speed was capped at 30 MPH, crawled back home, where the vehicle wouldn't start. I had to get it towed to the service center. All of this besides all recalls and software updates being addressed. There were multiple warning lights that went off during my drive: "Stop vehicle and check power supply" "Check electric vehicle system"

driving at around 35mph I heard a pop and a warning showed up on the dash stating "stop vehicle and check power supply". This warning put the car into limp mode as I was about to turn on to a busier road to get to my place of employment. The car was then towed, at the request of Kia, to the nearest dealership. It was diagnosed a few days later as having a faulty ICCU, or integrated charging control unit. There were no indications of the problem before the loud pop which I am assuming was a fuse blowing, and the car entering limp mode and showing warnings on the dash. This is a known issue by Kia as I have had my car in for multiple recalls regarding the ICCU.

I was on my way to the highway when about one mile from home when without warning vehicle went into Limp Mode. Acceleration suddenly dropped to 25mph. It was very dangerous trying to drive uphill on a busy road at limited power to get back to my home. Thankfully I was not yet on the highway. Dealer said that both the ICCU and fuse that were inspected a month ago due to a recall and found to have no error codes in January now need to be replaced. Parts on back order with no ETA.

Vehicle lost its power while trying to park. It could not be locked either. This is the second time this has happened. The first time, dealership said they replaced the auxiliary battery. When it got towed the second time, the dealership said, we only recharged the aux battery during the last complaint! Now, the dealership does not have anyone who can look into this issue for one week. Added to that, they do not have any loaner cars either! The car has 10,523 miles on it now. Car had 8000 miles during the first incident. We feel this is dangerous, unacceptable quality and not to mention, unbecoming of a vehicle brand not to give us a loaner car and expect us to wait a minimum of 10 days to figure out the problem.

In addressing your inquiries: 1. **Component or System Failure:** - The charging system of my vehicle malfunctioned at DC Fast Charger and all charging levels. This can be inspected upon request. 2. **Safety Implications:** - On January 2, 2024, charging issues at a DC fast station resulted in error messages, and on January 8th, I was stranded for 3 hours in cold weather with only 3 miles of range, posing a significant safety risk. 3. **Confirmation by Service Center:** - The issue has been documented with the dealership, but a comprehensive resolution is pending. 4. **Inspections by Others:** - The vehicle has not been inspected by the manufacturer, police, or insurance representatives at this point. 5. **Warning Signs:** - Error messages occurred on January 2, 2024, during a DC fast charge, and the severity of the issue became evident on January 8th, resulting in an extended charging time.

Well, at first I got the 12 V battery fixed because it wasn’t throwing the code because my 12 V battery wasn’t holding power and then I did get the code and it turned my vehicle into turtle mode where it would not move. This could’ve been very unsafe in the car. I have brought it in now and it has been 20+ days and I have not had resolution and I have not received the part to fix my car. I have been left as a single mother without another vehicle to use the dealership offered me a vehicle and I was driving that, but it has issues with the Wheel bearing and rotors which at first they told me I would be held liable for driving and then they told me to continue driving it since then now I am renting a vehicle which I cannot afford as I said I am a single mother and I can’t afford $300 a week and then we wait to be reimbursed by Kia they have done nothing to help me and my situation and I am concerned. I have had this car for less than two years. I have less than 24,000 miles on it and by Iowa lemon law it should be resolution into it getting fixed so I am making a formal complaint.

Vehicle does not charge at the full 11 kW it's rated for on a level 2 EVSE. It gets charge interrupted. I've had the SC311 installed which causes the car to lower the charging rate automatically instead of just dropping charge. But I still can't get the full charge rate. This occurs on my home level 2 EVSE, on each of the 12 level 2 EVSE ports I use at work, and out in town. The charging port gets extremely hot when charging and is not designed to pass the full 50 amps it's rated for. It struggles at anything over 25 amps. The extreme temperatures of the charging port can cause a fire or burns to people. The car needs to be recalled and the J1772 charging port and sensors needs to be replaced. This complaint is very common in the various EV6 owner's forums.

I do not yet know if the recalled part is defective. The dealer asked me to bring in the car for inspection and if the recalled part is defective then the dealer would order the part and I would be required to bring the car in again to have the part replaced. This requirement of having the customer return to have a defective part repaired puts the customer in the position of having to drive the car in a defective condition that could cause serious injury, whereas if the dealer carried the defective part in inventory this would not be necessary. Kia America will not let the dealer order the part unless it is first diagnosed as defective. In view of the fact that the issue is not attributable to the customer's care or use of the car, rather to the manufacture of it, the dealer's convenience should take second seat to the customer's safety and convenience.

On four separate occasions while driving on the highway between July thru November 2023; vehicle has had a loss of motive power (reduced speed) increasing risk of crash. Due to loss of motive power unable to accelerate to get out of way for merging traffic, also when approaching hills on interstate car would slow to speeds of less than 40 mph; unable to accelerate or move out of the way when fast approaching vehicles from the rear. I had taken the vehicle to a dealership on three occasions to seek resolution to only be told all diagnostic testing did not reveal any issues. Dealership has performed updates to the systems as well as recall update for ICCU upgrade, nothing to date has resolved this issue. I’m fearful to drive vehicle on highway that someone will slam into my car potentially causing harm or death.

The "trial period" of the Kia Connect ended. It was my understanding convenience features would be turned off. However, safety features such as the voice navigation (navigation still works, but you must type in the destination, which is dangerous), voice to text, and who knows what else, has been turned off. I believe this should be addressed.

While changing lanes on a freeway, the car passed through a narrow strip of slush from recent snowfall. The car immediately disabled the motors, preventing acceleration and regenerative braking for nearly 50 seconds. There were no warning lights, sounds, or messages displayed on the car's gauge cluster display, either for the initial loss of propulsion or for the restoration of propulsion. This caused a loss of traction when the car eventually passed through a patch of packed snow and ice.

Vehicle was normal and during the drive a warning light for "Check Electric Vehicle System" was shown, then a second warning light "Stop Vehicle and Check Power Supply" was shown, within 2 minutes the vehicle went into "turtle" or reduced speed mode and then finally the vehicle shut down completely. I was on city streets at the time and was able to park safely, but if this had happened on and interstate highway it would have been dangerous. This is a known issue with this vehicle as it ended up being an ICCU Assembly failure. There is also a safety recall for this, but Kia is not replacing the part and just doing a software update that is not fixing the root cause of the problem.

Was parking car. Pushed on brake and car accelerated

1. **Battery Pack Issues:** - The vehicle's battery pack experienced issues at DC Fast Charger and all charging levels, available for inspection. 2. **Safety Implications:** - Range anxiety began on December 11, 2023, with the vehicle serviced on December 22, 2023, and again on January 10, 2024, for low range due to battery pack issues. On January 8th, stranded for 3 hours in cold weather with 3 miles of range, posing a significant safety risk. 3. **Confirmation by Service Center:** - Two services conducted on December 22, 2023, and January 10, 2024, documented battery pack issues. The manufacturer attributes it to weather without a prior warning upon selling. 4. **Inspections by Others:** - No inspections by the manufacturer, police, or insurance representatives at this point specifically for the battery pack. 5. **Warning Signs:** - Range issues causing anxiety started on December 11, 2023, well before any service. Services conducted on December 22, 2023, and January 10, 2024, didn't significantly improve battery pack performance.

ICCU failure. Was confirmed by shop car was towed to over phone. But no mention of it on invoice as of yet. I was at traffic light when I heard a pop and when I tried to go, got the warning message to pullover and the turtle icon. I made it to a towable spot. Super fortunate all in all. Can’t imagine if on highway in weather. No hints of failure before. Car was recently purchased month prior. I took it in for recall within first week, was told all good, software was updated. I kept between 20%-80% at all times, charged lvl2 at work daily and lvl1 at home sometimes. Had cheap voltage meter in car and was reading fine. Hope to get my car back soon.

My Kia EV6’s ICCU failed while I was driving, leading the car to completely lose power while on a busy street.

El vehículo desde las 500 millas comenzó a encender el aviso de problema en sistema eléctrico , como era intermitente no pudieron arreglarlo , luego el sistema de entretenimiento se apagaba solo , la batería se sobrecalentaba mucho estando apagado y estacionado , por último dejó de recargar la batería , me dejó tirado en medio de la autopista , casi me accidento , lleva dos meses en el concesionario y aún no encuentran el problema

1) AC Compressor and components. 2) Puts me at a health risk because of no AC it’s hot outside. I shouldn’t have these issues with a 2023 vehicle. 3) My vehicle has been sitting at the dealership since June 12th and no one has touched it. 4) The dealership “claims they are just extremely behind, however I think they don’t have anyone that knows how to work on EV’s! 5) Coincidentally, after KIA sent out an over the air update in May is when this started to happen. A loud high pitched voice came from under the hood when the AC was “supposed” to have cut on. They said a supplemental update might fix it, however it didn’t. Now we are two months later with the vehicle sitting in the same spot and hasn’t moved…

It seems as if the ICCU on my car failed. It will not charge and went into limp mode in order for me to drive it home a few blocks.

ICCU FAILURE. Car would not drive

On several occasions, when traveling over 55mph, once the battery hits a certain threshold (35% or 55% so far) the “power is limited” warning will appear on the dash and the vehicle will lose power. This has not occurred at lower speeds but only at higher speeds, and not every time. This vehicle was purchased so my husband could do his freeway commute, but it is on a remote highway where there is often no shoulder, so it especially dangerous to suddenly lose power with limited ability to safely pull over. On one such occasion, he drove the vehicle straight to Kia for inspection. They said the soonest available appointment was in 2 weeks and because they had no technicians available, they could not run the diagnostic that would allow us to get a rental car in the meantime. They suggested going to a different Kia dealership. We called ahead and they said they could try to see it that day or the next, but when we arrived (with, again, the power failing on the drive to the next dealership), they said we were misinformed and they would have to hold the vehicle for at least a week with no rental option. We have since been unable to use the vehicle for commuting due to its unreliability and incredibly dangerous power failure.

On April 6, 2025, while charging my car my Juicebox tripped a breaker. When I reset it the Juicebox was showing errors and was inoperable. I tried to use my backup charger (Blink) but it tripped a breaker and became inoperable too. I took the car a commercial charger (ChargePoint) and it would not charge the car. Kept getting a “charge interrupted” message. The first Kia dealer I went to did not have a Level 2 charger and could find nothing wrong and refused to help repair the car. The second Kia dealer had a Level 2 and confirmed it would not charge, but Kia would not authorize a warranty fix. That dealer suggested leaving the car for a few days and hope the car generates a fault that Kia will accept to authorize a fix. •What component or system failed or malfunctioned, and is it available for inspection upon request? The Level 2 AC charging no longer works. •How was your safety or the safety of others put at risk? The car tripping 240-volt breakers and making two 240-volt chargers inoperable is concerning. •Has the problem been reproduced or confirmed by a dealer or independent service center? One dealer has confirmed the Level 2 charging no longer works. •Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It was inspected by a Kia service shop •Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? None

I was driving on a residential street at fairly slow speeds, like 25 mph. There was a stop sign so I engaged the brakes and the car did not smoothly slow down but instead it felt like the back tires locked up and a skid started and I actually went into the intersection before coming to a stop. There was no ice, no sand, just the road surface and the skid in the rear of the vehicle.

A couple of months ago the breaks started making a strange grinding noise and it starts vibrating for a few brief seconds, but violently. There are no warning lights or any indication of malfunction. I took it to the dealership and they allegedly fixed it. Nevertheless, less than a month later, the noise came back, and not just a noise, but the vehicle attempts to stop abruptly without me engaging the breaks. It happens intermittently, and it is quite scary when it happens while driving high speed on a freeway. It creates safety issues. This is not my first EV. I am very familiar with EVs, regenerative breaking, and so on. This is not a regenerative breaking issue. I don't even know how to properly describe it. it is very unusual.

Component/System Failure: The i-Pedal feature in the Kia EV6, designed for one-pedal driving through regenerative braking, consistently fails to stay engaged. This component is available for inspection upon request. Safety Risk:The erratic behavior of the i-Pedal function poses a significant safety risk. When the i-Pedal mode disengages unexpectedly, drivers must abruptly switch to using traditional brakes. This sudden transition increases the likelihood of delayed reactions and potential accidents, especially in heavy traffic or complex driving situations. Problem Reproduction/Confirmation: The problem has been widely reported by multiple users on forums and confirmed through personal experience. It has been noted that the i-Pedal mode disengages when the vehicle is stationary or when the battery is fully charged. Inspection by Authorities: The vehicle has been inspected by a dealer, but the issue persists due to a lack of awareness or understanding of the i-Pedal system among service personnel. No inspections by the manufacturer, police, or insurance representatives have occurred yet. Warning Lamps/Messages: There are no warning lamps or error messages indicating the malfunction of the i-Pedal feature. The issue is typically observed when the vehicle unexpectedly exits i-Pedal mode, requiring the driver to manually re-engage it using the steering wheel paddles. Assessment of the Incident:The inconsistency in the i-Pedal system's engagement appears to result from potential software bugs, sensor malfunctions, or design flaws in the regenerative braking system. This unreliability significantly impacts daily driving safety and efficiency. Recommendation 1. Software Update: Kia should release a firmware update to ensure the i-Pedal mode remains stable and reliable under all driving conditions and even after vehicle is turned off and back on.

While using I-Pedal mode the brake lights do not engage unless fully off of the accelerator. Even a large deceleration force does not engage any of the brake lights when coming to a full stop quickly. This is very dangerous as drivers behind cannot tell you are decelerating quickly.

I was driving my Kia EV6 2023 on I-110 in California when the driver rear tire suffered an instantaneous deflation. I was driving at or slightly below the 65mph speed limit, there was traffic in front and to the rear of me, the road surface was excellent. The tires had 11556 miles of use and were operating at the correct pressures as the vehicle has a tire monitoring system. The ambient air temperature was circa 76F. I was able to exit the freeway with some difficulty. The tire was a Continental Cross Contact 255-45 R20. I have been driving for nearly 60 years, had a wide range of cars and tires and never experienced an incident like that described which has all the indications of a product defect.

Car vibrated to degree it was hard to control. Initial tire balancing did not fix the issue. The tire was removed from the rim and a separated balled-up foam tire liner was found and removed. My concern is if this happens again in one of the other tires and causes an accident.

No abrasion, curb marks, track use or drifting (I'm 75 years old). Dealer service declined rotating the tires because mounting this one on the front could increase hazard in event of failure.

I received recall 24V867 from Kia dated 12/13/2024. The dealer alternately claims no knowledge of this recall, scheduled a service appointment to complete it, an today again claims no knowledge of the recall. Union Kia has put it on me to contact Kia America - that is not my job to correct their internal problems. Please advise. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Component/System Failure: The main components that failed or malfunctioned include the vehicle's charging system and battery management system, leading to significant range discrepancies and charging issues. Additionally, the coolant system issue suggests a failure in the vehicle's cooling system. These systems are available for inspection upon request to further diagnose and address the underlying problems. Safety Risks: The safety of the vehicle's occupants and others was put at risk due to the potential for being stranded in unsafe or remote locations, as experienced on [XXX], in Pennsylvania. The inability to reliably charge the vehicle and the coolant system issue could also pose a risk of overheating, potentially leading to engine damage or failure while in operation. Problem Reproduction/Confirmation: The range and charging problems have been repeatedly reproduced and confirmed by both dealership service departments and independent service centers during multiple service visits. The coolant system issue was also identified and addressed during these visits, indicating a persistent and recurring problem. Inspections: To date, the vehicle and its components have been inspected by dealership service departments on several occasions as part of the attempted repairs. There have been no specific inspections by the manufacturer, police, insurance representatives, or others outside of these service visits. Warning Lamps/Messages/Symptoms: Prior to the failure, there were instances of warning messages related to the vehicle's charging system and battery health. The first indications of these issues appeared shortly after purchase, escalating to the point of the vehicle being stranded due to insufficient charge. The coolant system issue was initially noted without specific warning lamps but was confirmed upon inspection during a service visit.

1. **Component/System Failure**: The vehicle's cooling system is repeatedly losing coolant, suggesting a leak or malfunction. The system has not been officially diagnosed due to technician availability but is available for inspection. 2. **Safety Risks**: The frequent need to refill coolant raises concerns about engine overheating, posing a potential safety hazard during operation. 3. **Problem Confirmation**: The issue has been consistently observed by the owner, requiring coolant to be refilled three times in 49 days. However, a formal diagnosis by a dealer or service center has been hindered by a lack of available technicians. 4. **Inspections by Parties**: The vehicle has not yet been inspected by the manufacturer, police, insurance representatives, or other third parties concerning this coolant issue. 5. **Warning Signs & Symptoms**: No warning lamps or messages have indicated a problem prior to noticing the coolant depletion. The issue was identified only through physical checks of the coolant level.

First year of ownership rear engine needed to be replaced. The car literally stopped where I was on the road and had to be towed to dealer. It took a month to get the motor replaced. After that, my car stopped while I was leaving my house driving it out of my driveway. There were red warining lights and sounds and then it just suddenly died seconds later. It had to be towed to the dealer. They said it was fixed and that the 12v battery wasnt being charged. Then I was leaving church when my car died on me again. Same issue. Now, the third time in this vehicles 2 years of life, my car died while I was on the highway driving to work in the morning in the passing lane during rush hour. The dash went red and waring lights and sounds with a message get to safety quick check electrical system and it only gave me a few seconds the car suddenly just stopped running and I was coasting on the highway to try to get to safety. I was going 70mph in the passing lane during rush hour, I could not steer to the left to coast off the road because on my left it was just a ditch no side road to stop on, I saw in the right lane a car that was a length or so behind so I cut my wheel straight across the right lane where I coasted to a complete dead stop barely making it to the side of the road. The side of this highway was barely the width of my car so traffic flying next to me was just inches away from my drivers side door.... I called roadside assistance and had it towed to the dealer. They then told me about the recall - which I had already had it into the dealer to fix the last time it was there for this same issue. The car is 2 years old and so far I have had it stop dead in its tracks on me 4 times! I have such stress and anxiety about continuing driving this vehicle as it is completely unsafe! I almost died last week when this happened. My safety and others on the highway that day were at risk. This could have been catastrophic.

ICCU failure. Car was dropped off with Kia and the (second) recall they claimed to have performed did not fix the 12-v battery charging system error. They ordered in a new part, which was on national backorder and they provided no ETA. I had to purchase a replacement vehicle after 30 days of them having the vehicle without making the repair, providing an update, or having given me a loaner. Received message it was fixed after 37 days, but no information whether it is with a new part. Subreddit for the EV6 shows this is a widespread issue that has not been permanently resolved. When the ICCU fails, you are limited to 25mph "limp mode" and will lose ability to move car if 12V battery dies.

On January 27th I was driving home on I-495 in the far left lane going about 70MPH when the electrical warning light came on. Telling me to stop the car and take to the dealership. While I was trying to get over into my far right lane, the car went from 70mph to 25 mph in about 40 seconds! Cars were flying all around me! It was terrifying and incredibly dangerous! The dealership discovered my ICCU had failed. This vehicle has a fatal flaw that is going to get someone killed.

I purchased my 2023 Kia EV6 in December 28, 2024. On January 8, 2025, I took my EV6 in for the SC327 recall service. Despite completion of the recall service, my ICCU still failed and my car lost power while driving on February 6, 2025. I was driving 45 mph down a state road and was about to get into a highway onramp when my speed quickly dropped to 13 mph and my car displayed a "check electrical system" warning. The car would not go above 13 mph. I was fortunate that no one was following close behind me and that I was not on the highway. Had I been in front of a truck or other vehicle that couldn't stop quickly, the sudden deceleration could have been very dangerous. I was fortunate that I was near a parking lot that I could pull into to wait for a tow truck. By the time I got into the parking lot my car completely died and I was stuck without heat in 19 degree F weather. There were no symptoms prior to the failure, and the first warning about the electrical system ("Stop vehicle and check power supply") appeared after I lost acceleration. This warning was followed by "12 volt battery low. Stop safely." before it died completely. The vehicle is currently at the Kia Dealership pending repair.

A small amount of snow / ice is sufficient to prevent the windshield wipers from returning all the way to the original starting position low on the windshield. For some reason this prevents them from functioning entirely - they just get stuck in a loop trying to go all the way down. I am able to lift them up manually but they won't do so under wiper motor power / while driving. I have a video that clearly shows the failure mechanics that this system won't allow me to upload.

I am submitting this as a supplemental statement to my existing NHTSA safety complaint regarding my electric vehicle, KIA EV6, 2023 model. Since my original filing, the vehicle has now experienced loss of power / loss of propulsion a total of three times. These incidents occur without warning, are unpredictable, and render the vehicle unsafe to operate. The vehicle can suddenly lose motive power, creating a serious risk of collision, particularly in traffic or at speed. The manufacturer and authorized dealership have been unable to identify the root cause or permanently repair the defect. Dealer documentation reflects that the issue “cannot be replicated,” and no corrective action beyond temporary battery charging or system reset has been performed. No explanation has been provided as to why the power loss occurred or how it will be prevented from recurring. Because the defect is intermittent and safety-critical, I no longer feel safe driving this vehicle and have stopped operating it entirely. A reasonable consumer would consider repeated, unexplained loss of propulsion to present an unreasonable risk to safety. I am submitting this update so NHTSA is aware that: The defect is recurrent (three incidents) The condition remains unresolved The vehicle is unsafe for continued use I respectfully request that NHTSA review this matter for potential investigation, as loss of propulsion in an electric vehicle poses a serious safety hazard to the driver and others on the road. Thank you for your attention to this safety concern. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2023 Kia EV6 experienced a sudden ICCU and 12-volt system failure while traveling approximately 50 mph. Without warning, the vehicle instantly lost propulsion and all electrical power. This included loss of steering assist, braking assist, hazard lights, shift capability (unable to shift into Park), and even the ability to lock the doors. The failure effectively “bricked” the vehicle in motion. I was only able to get the vehicle off the roadway because the road happened to slope downward into a nearby lot. Steering required significant physical effort, the brake pedal went completely hard (“dead”), and the vehicle offered no functional parking brake or Park engagement once stopped. Because I was on a hill, we had to allow the car to roll to the bottom until it met a curb to prevent movement. After power loss, the doors could not be locked at all. This type of unrecoverable electrical failure creates an extreme safety hazard for the driver, passengers, and surrounding traffic. There is no pre-warning and no diagnostic indicator. The ICCU fuse appears to fail spontaneously and renders the vehicle uncontrollable in several critical respects. This is not an isolated issue. ICCU failures have been occurring across the Kia EV6 and Hyundai Ioniq 5/6 platforms for more than three years, including on brand-new 2025 models. The persistence of this defect across multiple model years indicates that the underlying design or component defect has not been resolved by the manufacturer. Given the suddenness of the failure, the total loss of vehicle control systems, and the long history of similar incidents reported by other owners, I am now hesitant to drive the vehicle due to the unpredictable and dangerous nature of the defect.

The trunk continues to rattle after multiple trips to the dealership, it has been verified to not be the license plate or any loose components by the dealership. The noise sounds like the trunk latch striking repeatedly during regular driving. The sister model Hyundai Ioniq-5 has had numerous TSBs to fix this issue while Kia EV6 has had none published. And example of the TSB listed is [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I want to disclose this is the 2nd time this has happened. I was on the highway when the system failed. Immediately and drastically forced my car down to 25mph on [XXX] going to Philadelphia in the far left lane with no warning. I had to make it across 3 rows of traffic and ride on the shoulder of the highway until I could find a safe place. One ruining the sport tires on the car and probably messing up suspension since these cars are very sensitive and the highway does have those perforated shoulders. While cars zip past me I am having to figure out how to pull over with no force. None of the functions were working. It was traumatizing. Especially to do it again after 6 months ago the same thing happened. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving my car a warning flashed stating "check electrical vehicle system." Pulled over, contacted Kia of Abilene and asked if we could drive the car to the dealership. While on the phone another warning flashed ""Stop vehicle and check power supply." Attempted to drive car, "Limp mode or turtle mode" occurred and the max speed for the car was 25mph, sudden loss of acceleration. Made it home, which was approximately 2 miles away, and it seems like the 12V battery was draining quickly. Eventually the vehicle stalled at home and became unresponsive, no power. Contacted roadside assistance and the vehicle was towed to Kia of Abilene. All of this occurred March 29th at approximately noon. The dealership finally contacted us today, April 2nd, and notified us it was an ICCU failure and the part wasn't available with no foreseeable time-frame for repair. The car is absolutely inoperable!

On January 23 2025, while driving on the highway, the car lost power an had limited control. The car was towed to a dealer and it was determined that the ICCU failed. The car was at the dealer three weeks earlier for a recall related to the ICCU (ICCU (SC273A VCU SW LOGIC UPGRADE (VSC) • SC273A and ICCU INSPECTION/REPLACEMENT • SC302 ). Obviously, the recalls did not prevent the ICCU failure.

I have had 3 incidents where the ev6 went out of power. The one recent incident is when the car suddenly started giving red alert on low power and suddenly slowing down even when I try to step on the pedal to accelerate. Please see my video and photos of these incidents. And all these times my main battery of ev6 was always having charge higher than 40%. I was driving on all 3 occasions, once on highway close to the exit where I had to pull over to curbside. The ev6 has hence lost my trust since these type of sudden power failures could lead to my life straight being on risk - the 12 volt battery has died two times after I purchased the car in feb 2023! Kia themselves do not know what issues exist in the car- the recalls have happened three times, as I type this my ev6 is sitting at the west gate Kia service in wake forest, North Carolina since 17 days for a spare part called ICCU recall and replacement! I have been forced to lay an amount of $745 on this car every month and it’s draining me out financially and mentally. the worst part is since this is electric car , and you run out of battery power then it suddenly halts, if you are on high speed road on freeway no doubt you get hit by the car behind you and you die. I am not willing to put my life and my family’s life on danger when I drive this car anymore. Kia is not willing to buyback the car, I have paid a very high price for this and my car value has come down, leaving me a sum of more than around $10000 difference when I try to sell it back to Kia. This is injustice given that my life is in danger, I might face this experience again when Kia ev6 shuts on the power while I am on road, and I will get hit bythe car behind me and die. I need justice, I need Kia to buy my car back asap. I do not need to pay 745 monthly for this [XXX] car. Please help.

The EV-6 GT auto experienced a loud clunking grinding noise while steering 180 degrees when turning right and then left. The car skidded on the pavement this happened over a period of 3 months when the temperature was below freezing. After 2 service appointments Bridgewater NJ KIA dealership failed to diagnose the problem . On the 3rd visit they confirmed that the noise emanated from the summer performance tires that caused the tires to skid and caused the noise. Their solution was that storm tires would need to be replace the existing “summer tires”The existing tires are Good Year 255/40R 21. Not only that Good Year does not make snow tires of this size but when I first leased the car I was not told that the car would need snow tires to prevent skidding from snow or icy road conditions. There failure to notify car owners in the northeast of this hazard puts drivers at risk and potential for accidents in cold weather temperatures. Since I have not driven the leased car in below freezing temperatures and risk safety and hazards from driving on these summer tires I believe KIA should be held responsible for failure to notify drivers of this condition. I plan to terminate early the 3 year lease and also withhold payment until KIA acknowledges that they failed to identify this safety hazards and then did not offer to replace these tires to prevent future accidents. These “summer tires” were also Not clearly defined as racing tires with inability to provide adequate tread on icy and snowy road conditions. I am submitting this claim to prevent potential car accidents in driving the car in the northeast were weather conditions are periodic snow and icy conditions.

While driving with the power liftgate partially open, I experienced an inability to accelerate after coming to a stop. I pressed the accelerator and the car rolled gently forward into an intersection at a speed less than 2MPH. A warning displayed on the dash that I needed to close the liftgate before the vehicle would operate correctly, which was impossible because I was in the middle of an intersection with a large chair blocking the liftgate from closing. I was able to restore functionality by turning the car off and turning it back on. Prior to this, there were audible and visual alarms about the open liftgate after each stop. These alarms are described in the manual, which instructs the driver to close the liftgate when the alarms sound. However, driving with a liftgate open is a common use for an small SUV when hauling large or long objects, and contravenes no laws when done properly and safely. The manual does not state, so I did not anticipate, that the vehicle would enter a "limp mode" if I continued to ignore the alarms. Being unexpectedly unable to accelerate is a dangerous behavior, especially if you are in the position to make a left turn across traffic and the car goes into limp mode with cars oncoming. I consider this a safety concern because 1) driving with the liftgate open is not an inherently unsafe activity that warrants disabling the vehicle, and 2) the manual fails to state that the driver might experience sudden loss of ability to accelerate with the liftgate open.

My Kia EV6, AWD Wind has the exact problem described in this Ionic 5 video, [XXX] , which addresses your TSB 24-EV-003H. It appears my EV6 uses the same electric oil pump (EOP) as the Ionic 5, so I am not sure why the EV6 was not included in your TSB? The first 14 months I owned my car, I loved it, then in June after I started driving for 45 to 60 mins, the car ride started becoming rough or unsmooth. After researching it on the Internet and purchasing some diagnostic tools, I figured out, that when I start driving the car there is a demand signal for the EOP but the pump has no rpm, no torque and no DC current. Depending on driving conditions, it appears the rear motor stops propelling the car when it reaches 190 to 205 degrees and the front motor kicks in to do all the propulsion. Under the front motor propulsion, the car has a definite “lag” in responsiveness which I consider extremely unsafe as I expect to get an instantaneous response when I step on the accelerator not a lethargic response with no “zip”. It is similar to the difference between a turbojet engine and a turbofan engine. It has been to my Kia dealership’s service dept where they told me they duplicated the the switch from the rear to the front motor but after talking to Kia this condition was “normal” as the computer calculated this was the most efficient operation of the car I said that was BS and asked them if they checked the oil pump and was told yes. Bottom line, it’s the same EOP as the Ionic 5 and the EV6 has the same problems with it except there is no displayed fault code so Kia fails to acknowledge the problem. Also, based on what I see when the motors switch, the on board screen display shows the front motor with 5-7 bars of whatever the measurement is and the rear motor has only 1 or 0 bars but the OBD data shows both motors with the same rpm? Three EV6 problems: EOP inoperative, no fault code, data disconnect (OBD vs displayed data). INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The brake lights illuminate too early and often under [even very] gentle deceleration. My '23 EV6 GT is driven primarily in Level 1 (minimal) regenerative braking mode and the threshold for brake light activation clearly is far too low. The appearance of "riding the brakes" is dangerous because those who follow are not alerted when the driver transitions from [essentially] coasting to actually hitting the brakes. Also, at least in my mid-Atlantic suburban area, even the appearance of "brake checking" other drivers incites road rage, which I experience most days, especially when using cruise control, unless driving with regenerative braking disabled (Level 0). SC273 was necessary and prudent because the brake lights failed to illuminate under significant deceleration, confusing those who follow. SA541 was necessary and prudent because the brake lights illuminated inconsistently on uneven road surfaces, confusing those who follow. Another VCU software logic upgrade is necessary and prudent because the brake lights fail to distinguish between [essentially] coasting vs. significant deceleration, confusing those who follow, and potentially (demonstrably!) inciting road rage.

The contact owns a 2023 Kia EV6. The contact stated that while driving 72 MPH, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. In addition, the contact stated that the console displayed that the drive mode independently switched from rear wheel to front wheel only. The vehicle was driven to a safe location and parked. The contact allowed the vehicle to sit for approximately thirty minutes; then the vehicle was started the vehicle and driven to the destination. The failure reoccurred, and the failure was persistent. The vehicle was taken to the dealer; however, the failure could not be duplicated. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 8,000.

On [XXX], I went to charge the car at the Katy Mills location in Katy Texas. After fully charging the car, I went to visit my sister's house to visit. When I returned to the car it had completely shut down. I would not start and none of the electric components worked. I had to have the car towed to Westside Kia, who offered no assistance with a loaner car. I called three days later and was informed by Sabestian that the ICCU had blown out and the part is on National back order. There are three people in my home who are disabled and two young children who has to be driven to school. Upon further research about this ICCU unit, there is a total of 48,323 Affected Units and Kia Corporate has offered no assistance in buying this car back although it is still under the manufacturer warranty. If anyone can assist me with information on how to best handle this situation, I would highly appreciate it. So far I have paid over 2,000 in car rental fees, in lieu of my medical situation.

For about 6 weeks, after driving the car for more than 2 minutes, turning the car off and then coming back into the car within several hours (like when picking up kids from daycare, grocery shopping, going to restaurant, etc) results in no sound regardless of source, including ALL alert sounds for collision, blind spot, cross traffic, literally any and all sounds inside the car. Resetting the infotainment using the small reset button does not work. Unplugging and then replugging any fuses does not work. The only solution is after the car is turned off for several, typically 4 or more, hours. This is incredibly dangerous not just for the alerts, but because it renders Bluetooth calls impossible, resulting in having to use the phone manually while driving after trying to disconnect the Bluetooth connection. Others online have reported needing the amp replaced in order to solve the problem.

I leased a 2023 Kia EV6 vehicle and on October 30, 2023, I was 45-60 minutes into my first road trip when a warning displayed in the dashboard followed immediately by a reduction of motive power. The warning displayed was a turtle icon and the words “Power Limited.” Traveling on CA I-5 when this occurred putting me in a very dangerous situation. I navigated several lanes of traffic, vehicle decelerating, to reach the shoulder and pull over then to merge into existing traffic traveling at a high rate of speed only to advance 7-10 miles before the warning display reappeared. I then repeated the process another 7-8 times until I reached my destination. Later that day, again, 45-60 minutes non-stop when the warning display reappears for the second time and I’m forced to repeat the process another 7-8 times to make it to the dealership. I was told the vehicle had a warranty defect in the VCSM which had to be replaced. On January 25, 2024, the issue reoccurred for a third time after and I drove the vehicle directly to the dealership. I was told the diagnostic test did not reveal any codes and they had a service advisor drive the EV6 home, over an hour to see if he could recreate the problem. The service advisor experienced the same issue, twice, and the diagnostic scan did not reveal any codes. My safety and well-being have been compromised on three-separate occasions and twice with a dealership service advisor. I contacted Kia Customer Care Center and opened a case #15946871 and a tech-line case #16141516 was opened with Kia America. NHTSA opened an investigation on the 2022 Kia EV6 and the 2023 Hyundai Ioniq 5 which shares the same E-GMP electric vehicle platform. The investigation confirmed “a range of loss of power and varying time intervals between the warning message and loss of power and all power to the vehicle was subsequently lost, immobilizing the vehicle.”

The motor inverter for the rear motor failed while I was driving. The power cut out, and luckily I was able to drift over to the side of the road. On a highway, it would have been very dangerous. The dealer diagnosed the inverter issue, and said it needs to be replaced. The car has not been inspected by the manufacturer, the police, or insurance representatives. A warning message appeared the moment the power cut out. It said, "Check electric vehicle system."

When using 1 pedal driving, it isn't necessary to use the brake pedal to stop the EV. The EV6 will only illuminate the brake lights when the accelerator pedal is completely released, or when the brake pedal is depressed. Since using 1 pedal driving does not require depressing the brake pedal to stop, the following vehicle has no indication or warning that the EV6 is stopping. I have experienced several instances of near rear-end collisions because of this dangerous issue with the Kia EV6. I emailed Kia asking if they were going to offer an OTA fix and this is their reply, " Dear [XXX], Hello, This email is to let you know that as of now we are not aware of any updates coming out for this feature. Your complaint will remain on file here within Kia for review. Sincerely, Kia America. Curiously Kia's parent company Hyundai, whose Ionic 5 has the same problem, is receiving a fix which will illuminate the brake lights while using the same 1 pedal driving programming as the Kia EV6. Because the lack of 1 pedal driving brake light warning to following vehicles, I have turned this feature off until the issue has been resolved. I hope NHTSA takes this dangerous situation seriously and provides legislation to force auto manufacturers to adjust the conditions when brake lights must illuminate.
