2009 Kia Optima electrical system problems

After returning from work and parking my vehicle at home, the car sat in my driveway in 40 degree weather for approximately 12 hrs. I woke up the next morning and found my car on fire and is a total loss. The police and fire department were called and dispatched to my home. The fire department extinguished the fire and determined it was probably an electrical fire. There is no remote starter installed or any other accessories installed in the vehicle after purchase.

Tl* the contact owned a 2009 kia optima. While driving 35 MPH, another motorist notified the contact that the undercarriage of the vehicle was on fire. The contact coasted to the side of the road and noticed smoke and flames under the hood of the vehicle. The fire department extinguished the fire. A police report was filed and there were no injuries. The vehicle was towed to a tow lot. The vehicle was destroyed. The manufacturer was notified of the failure. The approximate failure mileage was 100,000.
