I got into the vehicle and when I started it a whooshing sound went off and boom, the whole car rocked and I turned to look at back and the truck was gushing black smoke. I turned off truck and got out and flames were coming out from both sides of the back tires and under truck at the gas tank and then it just went up in flames. It took the fire department to come and put it out. The only things that didn't burn where the two front tires and front fenders. Why would it start on fire from the back ?? Police and fire fighters even mentioned that fact.
