2026 Kia EV9 Electrical Problems

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.

While making a left turn at a four-way intersection, the passenger side front door opened the latch failed. This vehicle is equipped with motorized door handles that retract/flush when the vehicle is in drive indicating that the doors are locked. The door handles were retracted while driving the vehicle and making the slight left turn. During the turn, the passenger side front door opened and was a jar that could be indicated on the dashboard as well. This would put anybody at risk sitting in the passenger seat or causing an accident from the malfunction and alarm of the door. The vehicle was examined by a service department of a Kia dealership and parts of the door latch and or handle were replaced according to the repair order.

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

Instrument panel goes Black while driving. Keeps flickering on and off while driving. Took it to a dealer and they denied the flicker, even though I have 15 videos of it. Dealer just gave us the car back without fixing the issue and told us to live with it. This is extremely unsafe as we go up to a minute without seeing anything.

Incident

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.
