NHTSA Complaint #11641424 — 2023 KIA EV6

I purchased my 2023 Kia EV6 in December 28, 2024. On January 8, 2025, I took my EV6 in for the SC327 recall service. Despite completion of the recall service, my ICCU still failed and my car lost power while driving on February 6, 2025. I was driving 45 mph down a state road and was about to get into a highway onramp when my speed quickly dropped to 13 mph and my car displayed a "check electrical system" warning. The car would not go above 13 mph. I was fortunate that no one was following close behind me and that I was not on the highway. Had I been in front of a truck or other vehicle that couldn't stop quickly, the sudden deceleration could have been very dangerous. I was fortunate that I was near a parking lot that I could pull into to wait for a tow truck. By the time I got into the parking lot my car completely died and I was stuck without heat in 19 degree F weather. There were no symptoms prior to the failure, and the first warning about the electrical system ("Stop vehicle and check power supply") appeared after I lost acceleration. This warning was followed by "12 volt battery low. Stop safely." before it died completely. The vehicle is currently at the Kia Dealership pending repair.
