NHTSA Complaint #11686327 — 2023 KIA SOUL

I am reporting a recurring safety issue with my Kia vehicle that began around Labor Day 2025. The vehicle has abruptly shut down multiple times while I was driving on public roads in Hillsborough County, Florida. These shutdowns occurred without any dashboard warning lights, including while stopped at red lights and while in motion, creating dangerous traffic situations. Despite having a scheduled service appointment on September 5, 2025, I took the vehicle to the dealership a day earlier—on September 4—due to the increasing frequency and severity of the issue. Upon reviewing my service history (dating back to 2022), I found no documentation that the battery had ever been tested, despite regular multi-point inspections performed at the dealership. A battery test performed during the September 4, 2025, visit revealed that the battery was failing. I was required to replace it at a cost of nearly $400. The service team confirmed that the battery was draining and likely the cause of the vehicle shutting down. This issue could have resulted in a serious accident. I believe the failure to identify the battery problem earlier represents a potential safety oversight.
