Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“ICCU electrical system failed while driving (~1mi from house). Warning messages popped up and caused me to pull over and drive back to house under reduced speed. Kia told me car was not safe to drive and to tow car for repair under warranty. ICCU failure was confirmed by service provider and repaired after 2 weeks (diagnosis, part order, and replacement).”

NHTSA complaint #11746073, filed 2026-06

“My ICCU failed while I was driving and I lost power while in a light controlled intersection in Chicago. The screen turned off and I could not see my speedometer or any driving information. I luckily was able to roll to the side of the road and park the car. My car could not change gears, doors would not work, trying to jumpstart the 12V did not work.”

NHTSA complaint #11706602, filed 2025-12

“While driving at speed, I heard a pop noise from the car. A few seconds later, I received notification to check vehicle electric system. The vehicle slowed down despite my increasing throttle input. I was able to limp to a parking lot where it was flat bed towed. This experience matches a previous issue I had when it was diagnosed with an ICCU failure with the same vehicle.”

NHTSA complaint #11718449, filed 2026-02

“I had an ICCU failure. There were no warning lights . The dealership initially could not find the problem but when I brought it back again they did confirm the ICCU failed and replaced it. Failure of this causes the car to stop driving and lose power causing you to stop on the road as well as be unable to charge the car.”

NHTSA complaint #11704834, filed 2025-12

“The ev6 12 volt battery is not being charged by the main battery. It was recalled for overheating and not charging. I took it in and it was supposedly fixed. Took about three weeks. It happened again and I didn’t have my car for three weeks. I am now on my third time where the small battery is not charging and we were almost stranded.”
