ELECTRICAL SYSTEM
The ICCU unit failed and the car first slowed and then stopped. I was able to pull off the road at an intersection. A tow truck had to jump charge the battery to allow the car to be shifted into neutral in order to pull it onto the tow truck.

VISIBILITY/WIPER
Windshield cracking on new Kia EV6 with only 2700 miles. Was 53 degrees outside so no defroster excuse. Seems to be a stress crack and looking online in KIA EV6 Forums, I've noticed it is not a one-off problem as many owners have had to deal with this.

FUEL/PROPULSION SYSTEM
I was driving my car and the stop immediately and check battery sign came on. I had to have my car towed to the dealership. I read that the ev6 have ICCU problems and commonly need to be replaced. The car lost all acceleration and power and eventually stopped moving all together.

POWER TRAIN, ENGINE, ELECTRICAL SYSTEM
ICCU failure within three (3) days of buying vehicle. Only 300 miles on it. Failed to charge with known working Level 1 charger on day 1, successfully charged with Level 3 charger on day 2, and then failed to charge at same Level 3 charger on day 3. Simply connecting the Level 3 charger on day 3 had the car emitting "charger errors", and then followed that up with an "On board charger" fault. Vehicle no longer charges. Returned to dealer for repair.

ELECTRICAL SYSTEM
I was reversing my car in the parking lot and I heard a pop. Immediately I had a check electrical system warning. Preceding this the car was doing things which may have implied issues with the 12 V battery. Occasionally walking up to the car would not automatically open the car. Or other times, touching the driver handle did not unlock the car. The car is now at the dealership. They have confirmed failure of the HV fuse, ICCU failure, which also blew the 12 v battery. They have ordered the parts but it is currently on back order. The car could drive but after looking up this issue if the 12 v battery had drained it would have been inoperable.

ELECTRICAL SYSTEM
Started my car while I was out and heard a pop sound. Warning message appeared saying "check electrical vehicle system". I was able to drive but when getting onto the freeway, I started to lose acceleration and go into limp mode. I pulled over on the freeway and had to get car towed to dealership. Dealership service center confirmed that my ICCU part failed. The vehicle to my knowledge hasn't been viewed by anyone other than the dealership.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
initial filed #11708370 (1/2/2026) 2nd filed #11717025 (2/10/26) Yesterday afternoon (2/10/26), I was told by Jim Shorkey Kia Wexford PA that no error codes are on the EV6, it is ready for pick up. Before I received this call, there was a software update done on the EV6 (see service records) I attached 2 photos of the software update as well. ICCU ASSY was replaced, etc. was told per Shorkey Kia since there are no issues with my EV6, as of Friday when they initially called to say my vehicle was ready for pick up, Kia considers my problem resolved. I know I’ll be paying for the car rental for X number of days, even though the EV6 did not get the software update until this past Tuesday, yesterday 2/10/26, which cleared the 3 codes that were still showing on the Kia app earlier morning yesterday, screenshot of that attached as well. I have my car, no codes visible now.

ELECTRICAL SYSTEM
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.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER, FORWARD COLLISION AVOIDANCE: WARNINGS
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.

ELECTRICAL SYSTEM
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.

POWER TRAIN, ELECTRICAL SYSTEM, ENGINE
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.

ELECTRICAL SYSTEM
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.
