A new walmart-brand everstart plus 96r, 590 cca automotive battery was purchased on August 4, 2026, and installed in a 2016 Ford Mustang convertible. On the evening of September 26, 2026, my family and I drove the Mustang and returned home at approximately 11:00 p. M. The vehicle operated normally. There were no warning signs, electrical problems, overheating, or other indications of a mechanical problem. The Mustang remained parked and untouched overnight. At approximately 2:00 p. M. , 15 hours later, on September 27, my daughter came into the room and told me that the car was on fire. Riverside county fire responded to the scene. Fire personnel specifically asked whether the Mustang had been driven or worked on that day. I told them it had not. The vehicle had remained parked since approximately 11:00 p. M. The prior evening. Fire personnel continued to suppress the fire, investigated the engine compartment, cut the battery cables, photographed the vehicle, and advised me that the battery appeared to be the possible source of ignition.
