2025 KIA K5 Electrical System Problems

While driving in the dark this morning with my eight year old in the backseat, my headlights shut off, my entire dash including my speedometer, warning lights, radio, heat, heated seat and steering wheel, lost electricity.

Component/System Involved: The vehicle experienced a brief electrical failure affecting multiple systems simultaneously: exterior headlights, infotainment system, and dashboard indicators (seatbelt warning). All components recovered automatically within approximately 0.5–1 second. The issue appears electrical in nature (possible power interruption, grounding issue, BCM/TCM-related event). The vehicle is available for inspection upon request. Safety Risk: Yes. The headlights shut off completely while driving at night, even if only momentarily. This created a visibility loss and increased risk of collision, especially with surrounding traffic. The sudden loss and restoration of lighting was distracting and unexpected. Reproduction / Confirmation: The issue has occurred 4 times under different conditions (day/night driving). It has not yet been reproduced or confirmed by a dealer or independent service center.

The contact owns a 2025 Kia K5. The contact stated that occasionally while driving at various speeds, the front headlights, rear brake lights, and interior cabin lights illuminated very bright. No warning light was illuminated. The vehicle was taken to a local dealer where unknown repairs were performed; however, the failure persisted. In addition, the contact stated that the transmission was replaced prior to the recurring failure by the same local dealer. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 24,000.

While cruising at approximately 40 mph on a surface street, the car lost all power, completely shutting down. After rolling for two seconds it turned back on.

Battery keeps dying even after replacement. I would drive it then park it overnight and the next day it would dead. this put my safety at risk because at any time my car could die and I wouldn’t know until I sat in it. I would then have to figure out what to do next since the last 3 times it has died i was stuck with important work to do. There were no warnings or symptoms that first appeared. We have taken it to the dealership and they replaced the battery, but it has died again even after battery replacement.
