2025 Kia EV6

KIA has created a safety hazard by removing the ability for the driver to select LIGHT or DARK mode for the two 7" data and infotainment screens in their 2025 and forward EV6 electric cars. Like many, I have to drive in very fast busy commuter traffic on highway I-66. (exaserbated by driving into the sun in the AM) The DARK mode screens have insufficient contrast even with the screen lighting turned all the way up. It takes the drivers eyes away from the road longer than is safe, particularly in high speed freeway commuter traffic. This is seriously exacerbated if the driver uses sunglasses because of the sun. This is obviously not an issue confined to highway I-66, or me.

While driving on a sunny day on a 35mph road, my dashboard reported “Check Electrical Vehicle System”. A red battery symbol appeared and my cruise control disengaged with a message “requirements not met”. When I got home I read my 12 volt battery monitor that reported the battery was 11.99v and only had a 60% state of charge. Just prior to this short drive from home, my battery was 12.77v and had a 100% state of charge. I put in my ODB reader and it provided two error codes: P1A9096 and P1A961C. The first error code is the result of an ICCU failure in its DC to DC circuit (the one that charges the 12V battery from traction battery). Using a battery charger, I was able to fully recharge the 12volt battery. My monitor says that it’s healthy with 100% state of charge. Turning the car back on resulted in a rapid drain of the battery from 100% to 93% in just five minutes while parked. The electrical system failure warning lights are still lit. I’m having my car towed for repair. If this failure had occurred more than 10 minutes from my home, I would’ve been stranded.

I START VEHICLE AND TRY TO PUT TRANSMISSION TO DRIVE ITS NOT WORKING AFTER I TRY TO PUT VEHICLE TO REVERSE TRANSMISSION ITS NOT WORKING

Steering rack need to replace after drive almost 1900 miles. It has knocking nosie when turn the wheel, the car had been in the shop for three weeks.

ICCU failure.

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.

ICCU and fuse failure when it was being moved out from the garage. Got a “Check electrical system” notification when I turned it on following a level 2 charge the night before. It was with the dealer for exactly one month before I was able to pick it back up.

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.

ICCU failure. Car lost power while driving. I heard a "pop" sound and then the car displayed a warning light moments before losing power. Car was towed to the dealership where they diagnosed and replaced the ICCU and a fuse. This is a known problem since the 2022 model year and seems to be a very common failure that the manufacturer is unable definitively repair. Thankfully I was on a local street and not on a highspeed highway when this occurred.

Car has an NACS charger port, and is advertised by KIA as compatible with Tesla Superchargers and home chargers. The car will not charge at a supercharger nor at home using a Tesla charge cord that works with a Tesla Model 3.

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.

ICCU failure. Pulled out of driveway, heard a pop, received warning to pull over and check vehicle power. Car had to be towed to dealership but they are experiencing so many of these failures that they are extremely backed up on even being able to check out the car.

The ICCU unit failed. Limited speed and no charging capabilities. The Dealer has been informed and an appointment has been made 3 weeks out as they are too busy. The ICCU has not been inspected yet. No warning lamps or messages appeared before the problem started. After a loud POP or bang in the rear of the car 1 warning light appeared and 1 message. (See Attached) POP happened at 16:15 hrs on the attached graph.

The battery had an electrical system failure warning after 5900 miles and has been in the shop for over a month.

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.

ICCU failure

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.

When shifting from reverse to drive there was a loud pop towards the back up the car. A check electrical system warning popped up, and then eventually a Check Power Supply stop now warning came up. The vehicle would not go above 26MPH and had to be stopped in a parking lot to be towed to the dealership. The ICCU went out and needed to be replaced, was at the dealership for 2 weeks for replacement.

ICCU failure at 3889 miles not charging and 12v battery failure

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.
