In owners' own words
I had an ICCU failure on 4/12/26. I was fortunate enough to be close to home, so I was able to get back home before the vehicle dropped into reduced power mode. As has been reported many other places, I heard a loud pop and moments later a number or warning messages came up on the display. It was towed to the dealer the following day and has been confirmed to be an ICCU failure. Electrical system
We purchased a certified pre-owned 2024 Kia EV6 GT on 6/5/2026. On 6/6/2026 while driving on city streets, the display screen suddenly displayed a large and flashing red warning message "Stop vehicle and check power supply" in addition to the battery symbol. We took the vehicle to the dealership and they diagnosed that the ICCU had failed and needed to be replaced. Electrical system
The vehicleâs ICCU unit stopped working out of the blue. This happened on a busy intersection and the car came to a sudden and violent halt. Luckily we were not involved in an accident. Itâs a very well known issue with these vehicles and itâs really criminal that Kia has done nothing to fix it. They just change the ICCU unit and then it happens again. Electrical system
