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 01/08/202…

I reported it to the selling dealer within days of delivery. Authorized Kia dealers have attempted repair four times over thirteen months, including tire replacement, multiple road force balances, and alignments. The de…
