Unknown what caused the fire per fire department. I drove to my bosses house and parked the car for about 15 minutes. I was about to leave in the car right before the fire started. At 12:05PM on 09/22/21 the car started smoking and fire appearing under the car. My safety and other by standers was put at risk by the thick black smoke and flying debris from the car. Thankfully I was not driving when the car caught fire. There were 4 different explosions two of which I believe were the two front tires and the gas tank. The Saint Louis County police and West County EMS & Fire protection both took a report but I do not have a copy of it. No warning signs or lights on the car when I parked it.
