2023 Kia EV6 Complaints

While driving a rented 2023 Kia EV6 on the freeway, the vehicle lost power and shut down completely, without warning, on multiple separate occasions during a single trip. This occurred at highway speed in live traffic, creating a serious risk to vehicle occupants and surrounding traffic. The vehicle was a rental (Dollar Rent A Car); no external damage or collision was involved. The vehicle has since been towed.

ICCU failed and replaced under warranty

First ICCU the power completely went out on 2/23/26. Power went out again April, 2026. Currently car is immobile and unreliable and not safe for driving due to power failures. Towed car to Kia Cerritos. Car supposedly "fixed" (with other issues I've reported to KIA of America & CA BAR/DMV) Currently 12V battery is not holding charge as of 4/27/26, 4/28/26, and 5/2/26. I received a letter from KIA stating ICCU and inability to charge, Keep this Letter in your Glove Box for a free diagnosis and possible no cost servicing. As an older American this is inherently unsafe, as I travel for work and cannot be stuck on the road. The vehicle suddenly loses power in traffic. It simply stops running. This is my 5th attempt to file this very complaint between April and 6/14/26.

ICCU failure, a well known issue with these cars.

Iccu failure with Kia ev6. Unreal that this car has not had a recall yet. It is totally unacceptable that this car can at any time fail. Car will not start and shut down while I was driving. Luckily I was beginning to park when it happened
