2022 Kia EV6 Engine Problems

Vehicle Safety Complaint My Kia experienced an ICCU (Integrated Charging Control Unit) failure and was at the dealership for approximately two months while awaiting repairs. The ICCU and related components were replaced, and I was told the vehicle had been repaired. However, immediately after I received the vehicle back, the “Check Electric Vehicle System” warning illuminated again. Since that time, the vehicle has continued to experience serious electrical issues. The vehicle has unexpectedly shut off while stopped at red lights and has failed to restart on multiple occasions, leaving me stranded. This creates a significant safety hazard because the vehicle can lose the ability to move while in traffic, placing me and other motorists at risk. I have returned the vehicle to the dealership twice since the ICCU replacement, but the problem has not been resolved. The dealership has been unable to identify or permanently repair the defect. I have been without my vehicle for nearly three months this calendar year due to this issue. More importantly, I no longer feel safe driving the vehicle because I cannot trust that it will remain operational in traffic. I am submitting this complaint because I believe this represents a serious safety defect involving the vehicle’s electrical system and propulsion system. I request that NHTSA investigate this issue to determine whether other Kia owners are experiencing similar failures and whether additional action is warranted to protect consumers.

I am reporting a recurring safety and reliability issue with my 2022 Kia EV6 GT-Line (VIN: [XXX] ). The vehicle currently has approximately 63,100 miles. The vehicle repeatedly displays a “Check Electric Vehicle System” warning message. This problem has occurred three separate times. On at least two occasions, the vehicle became undriveable and required towing. The failure appears to affect the vehicle’s electric powertrain or control systems. The vehicle is currently being taken again to the dealership (Lou Sobh Kia in Cumming, Georgia) for diagnosis of the same issue. This will be the third service visit for this recurring failure. Because this issue can cause the vehicle to become unexpectedly inoperable, I am concerned about the safety implications and believe it may indicate a broader defect affecting Kia EV6 vehicles.

The iccu failed on this car rendering the whole vehicle useless. This part is currently a recall and I was using a new ICCU with the software update per their recall solution. My second ICCU failed at approximately 40k miles.

Incident

Dec 9, 2025

Persistent ICCU failure causing charging interruptions, “Check Vehicle Charging System” → “Stop vehicle and check power supply” warnings, low 12V battery voltage (down to 12.1V), and risk of power loss/strand. Kia Connect sent “Charge Interrupted” alert during a session that reached 99%. Multiple prior recalls/attempts failed to resolve (Sep 2023 TSB ELE291 BMS, Jun 2024 SC271 ICCU SW, Jan 2025 SC273 VCU SW, May 2025 SA5999 limp-home logic, Sep 2025 dead 12V stranding). Towed Feb 2026 after stranding; dealer confirmed ICCU failed (DTC P1A9096), replaced ICCU (P/N 36400-1XFA0AQQK latest revision), fuse, and SW update under SC327 (24V-867). Repair completed same day (Feb 24, 2026), but dealer skipped charging system test and filling coolant. Safety impact: Stranded wife twice (dead battery and iccu failure), tow required, potential sudden power loss while driving. Report purpose: Document recurrence despite multiple recalls; seeking NHTSA tracking for effectiveness of SC327 remedy.

Incident occured october 17, 2024. Was driving approximately 30mph on a local road when lights flashed to "check electric vehicle system". Was speed restricted to 25mph (on 45mph road) and was able to make it back home approximately 1 mile away. Car completely shut down in my street prior to making it to my driveway. It needed to be towed to the nearest dealership. No lights in dash working and flickering. Prior to this failure over the preceding several months there were errors where I would plug the car into Level 2 charging at home (9.6kWh) and the car would stop charging with a hot charging port approximately every 1 hour. I would unplug and replug in again. Charging would work. Level 3 was working just fine without problem. After going to the dealership it was deemed that the ICCU component needed to be replaced. After replacing car worked well and no charging issues occured.

The AC charging for this car stopped working around [XXX]. After 3 trips to the dealership for repair I brought it back a 4th time and because the dealership was unable to repair it they gave me a loaner to use while they tried to figure out the problem. During this time they removed the entire battery from the car, dropped the suspension, experienced the car not being able to go into gear (reverse or drive), not hold a charge etc. The car has been 100% inoperable since [XXX]. Today, 01/27/26 the dealership phoned to let me know that a regional Kia technician came by and realized there was just one screw that needed to be tightened and now the car works perfectly and I can come pick up my car and bring the loaner back. There is no way I would ever feel safe driving that car again. Kia America offered me a buy back with the condition that I pay them $9,350 in depreciation.

I am reporting a failure of the ICCU (Integrated Charging Control Unit) in my 2022 Kia EV6. The vehicle became inoperable within weeks of purchase and has remained at a Kia dealership for over six weeks. The failure caused the vehicle to suddenly lose power and become undriveable, which is a serious safety concern. This issue appears to be widespread among EV6 owners. Despite the issue being covered under warranty, Kia has not provided an acceptable resolution. I believe this failure presents a risk of sudden vehicle disablement and should be investigated for safety-related recall potential.

I purchased my car 08/08/2022, my car stopped charging by June 2023. I took it to the shop and was told, it was my charger. In August of 2023, I was told it was the ICCU. From 06/2023-12/07/2024, I had a total of 9 recalls on this car. Kia did not notify me at all for any recall with the exception of the second one that occurred in December of 2024 (the 9th recall). Some of the recalls I found online when my car failed to charge, one my insurance company notified me of and others I found out when I had other issues with my car.

Incident

Dec 9, 2024

On multiple occasions, while driving on the freeway, the vehicle experienced a clunking noise and complete loss of propulsion. Safety was put at risk as the vehicle had to navigate off to the shoulder of the freeway at a speed significantly slower (due to no acceleration available) than traffic with reduced braking capability. Once on the shoulder the vehicle needs to be turned off then on again then it functions as normal. Due to the intermittency of the issue, the dealer was not able to reproduce the problem, therefore they will not fix it. When the issue occurs, there are no warning messages on the display. The dealer has stated there are no error codes stored in the computer. This issue seemed to go away after an ICCU fix was applied, but came back after the ICCU recall was recently applied. This incident has occurred on the following dates: On freewayFeb 2023 On FreewayJune 2023 On FreewayJuly 7 2023 On FreewayJuly 20 2023 On FreewayJune 26,2024 On FreewayAugust 20,2024 3:13 PM On FreewayAugust 24, 2024

The contact owns a 2022 Kia EV6. The contact stated that while the vehicle was parked on a hill, it rolled and crashed into a handicapped sign. The forward collision sensor became inoperable. While at the charging station utilizing the radio, the battery and collision warning indicator lights were illuminated. The vehicle was taken to the local dealer where they were unable to identify the failure. The vehicle was not diagnosed or repaired. The manufacturer was contacted but provided no additional assistance. While driving, an unknown vehicle crashed into the rear of the vehicle and a quarter panel. There was no reported injuries, fire, or police report.
