The vehicle was operating normally the previous night. We drove it and parked it in the driveway that evening, and it was not used again after that. The following morning, we started the vehicle to allow it to warm up and then returned inside the house. Approximately 10 minutes later, we discovered the vehicle was on fire, with flames coming from under the hood. We immediately called 911. The fire department responded and was able to extinguish the fire; however, the vehicle was completely destroyed, and part of our home sustained fire damage. There were no prior issues with the vehicle. We had purchased it in September 2025, and it was in excellent condition. This incident could have resulted in far more serious consequences had it occurred while the vehicle was in motion or if emergency responders had not arrived as quickly as they did.
