2025 KIA EV6 Complaints

I charged overnight at work. When leaving I heard a loud pop and the check EV system light came one. The vehicle would no longer drive over 40mph. I made it a mile and it dropped to 20mph. The dealership has had my car for over a week. From research it seems to be the ICCU as many others have had problems with.

prior case 11708370 filed 1/2/2026 spoke with [XXX] 1/22/2026. Friday 2/6/2026 Shorkey Kia Wexford calls and tells me my EV6 is fixed I can pick it up. I go into the Kia App and still have the same 3 codes as before; P056216 VCU, C160404 FR_Radar, and C28B186 ADAS_DRV. I tell them later that day when I had time to open the app to make sure the codes were corrected, called them back and said until these codes are cleared, my vehicle is not fixed. Tuesday 2/10/2026 I get a called from same person at Shorkey Kia in Wexford, telling me my vehicle is fixed, I can pick up my vehicle, same person her name is Maggie. I told Maggie to hold while I bring up the Kia app, I still see the same 3 codes: P056216, C160404, C28B186. I told her the codes are still active, and as long as these codes are present, the car isn’t fixed. She wouldn’t tell me what was done to the car, so I don’t know if the ICCU was replaced or not. However from browsing the EV6 Owners USA group, [XXX] had the same issue, and his car was fixed per whatever Kia place that is around him. He still has the P056216 alert and was told it will go away after whatever period of time. This is what the Kia repair place told him.

11/28/25 on freeway car lost power and would only go 25mph and warning light came on. After short distance full power came back. 12/14/25 earliest appt with dealer and could not find problem. 01/09/26 Lost power and took car to dealer. Dealer said bad battery and they replaced battery. 1/20/25 lost power again and limped to dealer. Dealer found bad ICCU. They are now waiting for new ICCU to replace. When your driving 55 mps on freeway and suddenly drop to 25mph this is dangerous. The apx date required below is when I have taken the car and dealer confirmed ICCU problem not the original problem date of 11/28/25.

I have experienced a ICCU failure at 7200 miles on my 2025 EV6 GT Line. This failure is a safety hazard as it will quickly disable the vehicle and strand the occupants wherever they be at the time of failure. (highway, back roads, day or night). There are warning lights when this occurs, but there is a very limited time to get to safety, depending on the state of charge of the onboard 12v battery. This issue has been ongoing since this vehicle came out in 2022. There have been a number of recalls to address the problem, but apparently without success. I see postings all the time with others experiencing this failure. When I inquired about the availability of the replacement ICCU, I was told that the part was on national back order. I was also told there were 147 units in transit, 47 were already spoken for. This seems to indicate that this is a very common issue, affecting many drivers.

Failure to charge properly on both alternating current and direct current platforms. Trips electrical breakers at residence while charging at home on AC current. The vehicle will only DC fast charge for a few minutes before charge session is prematurely terminated. I have been told by the KIA that it is a failure in the integrated charge control unit (ICCU). They told me there were 47 current problems right now in the state of Tennessee. I have not been issued a recall at this time. The logistics for getting a new ICCU could 2 weeks or greater. This problem could be catastrophic on long road trips.

Was driving around 45mph when I heard a pop noise, like an over pressurized soda bottle popped open. Moments later car abruptly dropped to under 35mph and reported errors and to check battery system. Brought it into dealer and they confirmed my ICCU failed and had to be replaced.

While driving on a busy road at night, my vehicle displayed battery warning lights and went into "limp mode" which slowed me down to 25 mph before stopping completely. I was then stranded until a tow truck could be dispatched. The Kia dealer told me that the issue was an ICCU (integrated charging control unit) which they have to order. I have since learned that this issue is known and is common.

Was driving home lost all power. Caution lights came on. The ICCU, relay switch, 2 fuses. went bad. It took 9 weeks for KIA to fix, no compensation.

Erratic behavior before pulling out of parking lot: STOP vehicle check power, check 12V battery Stop safely engage parking brake. All dash lights started flashing, going black, power couldn’t be maintained, thankfully not on highway yet. Complete car failure, had to have 2025 EV6 jumped 4 times, battery still showed 41% charged, couldn’t keep charge to even get car in neutral for tow or doors locked. After each jump from tow company, power would last for less than 3-5 seconds, then dead, completely dead vehicle nothing worked.

After 2474 miles, the vehicle Integrated Charging Control Unit (ICCU) failed in my 2025 Kia EV6 making the vehicle undrivable so it had to be towed to the Kia dealer. The ICCU was replaced under warranty. The failure of the ICCU in Kia, Hyundai and Genesis electric vehicles is fairly common and they have yet to come up with a permanent solution.
