Example complaints

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

“The engine/power of my electric EV6 died. It went into limp home mode (speed limited) briefly before dying completely. I restarted it and was able to get it to a parking spot before it died again, but I was just lucky I was on a surface street with parking. Dealership confirmed it was an ICCU failure”

NHTSA complaint #11714044, filed 2026-01

“Dear Kia Customer Care, I am writing to formally report a serious and recurring safety issue with my Kia vehicle. I have repeatedly experienced a Power Limited error while driving, often accompanied by a turtle icon and a Check Electric Vehicle System warning. On multiple occasions, the vehicle has suddenly lost power and stalled in the middle of the road. This is extremely dangerous and has put me and other drivers at risk. A vehicle should never lose propulsion unexpectedly, especially in active traffic conditions. …”

NHTSA complaint #11767230, filed 2026-09

“The vehicle’s 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. It’s a very well known issue with these vehicles and it’s really criminal that Kia has done nothing to fix it. They just change the ICCU unit and then it happens again.”

NHTSA complaint #11732893, filed 2026-04

“Listing as all 3. ICCU/fuse went out, car decelerated to 45 MPH max and flashed a warning to pull over. The bottom left battery indicator for the 12v battery also changed to red, indicating it was not regaining power from the main EV battery. Currently in shop hoping to get part in soon”

NHTSA complaint #11733307, filed 2026-04

The car on 3/7 came up with “Check Electric Vehicle System” reverted to page 1-46 of Manual and advised do not drive, tow to nearest dealership. We drove car 4 miles home and the car had next to no acceleration, extremely dangerous and people nearing to back end us. To try and charge vehicle response is unsuccessful”
