2024 Kia K5 Electrical System Problems

My brand new 2024 Kia K5 has been at Kia of temple hills since February 23, 2026. The dealership has stated they do not know how to diagnose or repair the issue and indicated they needed a special diagnostic tool from the manufacturer. The vehicle has now been out of service for an extended period with no repair timeline provided and no communication from them at all. I also have not been provided a loaner or rental vehicle during this timeframe. While driving with my toddler child the steering wheel gets tight the speedometer isn’t reading correctly. Dashboard lights up like a Christmas tree with almost all warning lights on and messages to check every system: from tire pressure to forward collision to RearCross-TrafficSafety and the list goes on

On three occasions, my car cutoff on me. Once on the highway at 60+ mph. The dash would go out, then all indicator icons popped on. I've been to the dealer twice & now a third time. They found nothing. AAA diagnosed low alternator once.

The contact owns a 2024 Kia K5. The contact stated while driving 60 MPH, the vehicle inadvertently lost motive power. The contact was able to pull to the shoulder of the roadway, where the vehicle was able to be restarted. The contact stated that several unknown warning lights were illuminated. The vehicle was taken to the dealer, who was unable to determine the cause of the failure. The vehicle was not repaired, and the failure reoccurred. The vehicle was taken back to the dealer, who then diagnosed a failure with the throttle body. The vehicle was repaired, but the failure reoccurred. The vehicle was then taken back to the dealer, who diagnosed an additional failure with the main wiring harness array. The vehicle was repaired. The manufacturer was notified of the failure but did not assist. The failure mileage was 3,000.
