2022 Kia Niro Electrical System Problems

This car was purchased certified pre-owned from a Kia Dealership with 46,227 miles in October 2024. Within a month (Nov 2024), the electrical system would die overnight and we would require a jump start. This seemed to align with colder temperatures. After the first or second jump start, a headlight blew out. We replaced it. Then a tail light blew out and we replaced that one too. It seemed that there must be a connection between the electrical failure and the headlights / tail lights burning out. We took it in for a software update to see if that solved it, we also had them check the hybrid battery and the 12V battery. No other issues were detected. Eventually the problem just stopped happening. Now in Nov 2025, a year later, the problem has returned. The car's electrical system dies overnight and we have to jump start the car. And another tail light / turn signal has burned out. This time, we called a dealership to ask about any recalls or pending software updates and they said there was nothing showing in their system. We are now driving without a turn signal, which is a significant safety hazard. We will have to go back and replace the tail light / turn signal bulb. But what about the situation recurring? How do we get the car to stop 'dying' overnight in cold weather?

The contact owns a 2022 Kia Niro. The contact stated that the rearview camera displayed a distorted image while the vehicle was in reverse(R). The failure obstructed the driver's visibility, preventing the driver from safely operating the vehicle. Additionally, there was a delay with the image appearing on the screen when the vehicle was in reverse(R). The vehicle was taken to the dealer, but it was unknown if the vehicle was repaired. The contact stated that on a separate occasion, the vehicle failed to start up, with the check engine warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed that the battery terminals were loose. The vehicle was repaired; however, when the contact arrived to retrieve the vehicle, the vehicle failed to start. The dealer inspected the vehicle; however, no cause for the failure was found. The contact was informed by the dealer that the vehicle had an open recall, NHTSA Campaign Number: 25V426000 (BACK OVER PREVENTION). The vehicle remained at the dealer unrepaired. The manufacturer was not notified of the failure. The failure mileage was approximately 45,000.

I took my car to the Dublin California Kia dealer because my car would not start or allow me to open the doors. When I had it towed to the dealer they said that the lithium ion battery under the rear seat had swollen. They said they would first address the recall for the (HCA) recall number 23V534. They completed the recall and was given the okay to replace the battery. Car was in the shop for 2 weeks. When I got the car back I didn't drive for 4 days. When I went to drive the car it would not start again. I had the car towed to Kia Vacaville, California shop. They informed me that the recall was performed incorrectly at the first dealer and that the new battery under the rear seat was swollen. The car has been in the shop for 2 weeks again. I am very concerned that this is a dangerous problem and do not feel safe driving this vehicle.

Car keeps notifying me of an issue with my left break lights, it has been inspected twice to which both times, Kia services said it just needed a new light but yet this problem keeps happening. Nothing pops up on diagnostics and there are no recalls, this is a brand new car less than a year with no history of accidents. It’s a safety issue now because it could be a wiring issue.
