What owners report
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. On 01/08/2026 the service department stated that the tech was "tinkering" on the car and would reload software updates and patches. On 01/09/2026 the service department informed me that the technician still does not know what is wrong with the car and the tech is off again today.
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. Second dealership brought in techline specialist that ordered Kia Warranty repair would replace the entire roof. The vehicle is at a third party auto body repair shop.

I am submitting a safety complaint regarding a serious incident involving my 2025 Kia EV9. The vehicle was serviced on March 1 at World Kia in Joliet, Illinois. On April 4, only four days after that service, the vehicle experienced a sudden and unexpected ICCU failure while I was driving. During my normal travel, in active traffic and at speed, the vehicle abruptly entered limp mode and displayed multiple system warnings. This caused an immediate and significant reduction in power, creating a hazardous situation for myself and surrounding drivers. I was forced to maneuver the vehicle out of traffic while it was rapidly losing propulsion capability. The vehicle is currently at Berwyn Kia in Berwyn, Illinois for diagnosis and repair. I am reporting this incident due to the clear safety implications of a sudden loss of power during highway driving operation. …
