Example complaints

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

“I own a Kia 2026 EV9. We charged the car to 80% (we have reduced the limit to only 80%). The next morning there was no power to the car. The interior lights would not come on door handles would not work. I could not start the vehicle. I read on line of the 12v battery dying and ICCU failures. I charged the battery for 1.5 hours and was able to get the car to start. I immediately drove it to the Kia dealership on 01/05/2026. The service department stated they could charge the battery but had to further diagnose the problem. …”

“I was sold a vehicle with a manufacturer defect. At purchase there was a loud wind noise coming from sunroof. I was promised a swift service department visit to realign the sunroof. At service visit ten days later the dealership replaced sunroof and threw electrical error codes B271100. After a specialist over rode the error the dealership claimed fixed and had me pick up the vehicle. The loud wind noise was still present. When I attempted to return the vehicle the dealership said I would no longer be serviced by their dealership. Kia Customer Care sent me to a second dealership. …”

“Vehicle would not accept a charge requiring it be towed 120 miles to nearest Kia dealer. Vehicle had no warning lights or messages, just would not accept a recharge of the drive battery.

“Car was driving find and suddenly check electric system message came in with a red battery indicator. The application for the car indicates an ICCU P1A9096 error code. ICCU errors seems to be common with Kia/Hyundai electric cars. Car went to limp mode and wouldn’t let drive it more than 45mph which it was dangerous in the highway. I was able to get the car into the dealer but the last mile the car was very limited in power with no more than 30mph. Radio, A/C and other accessories stop working”
