ICCU failure. Total and sudden loss of power. No acceleration. "Limp mode" activated for 5 miles before total shut down.
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.

At 4,000 miles the car had an electrical warning failure that required Kia to replace the gear reduction unit.

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.

EV car won't charge.
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.
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.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
