NHTSA complaint #11350207, filed 2020-08, 191,600 miles

“I had left my lights on and battery went dead. Went to jump the vehicle and charge the battery. Cables connected correctly. When I went to start the vehicle, I heard a loud explosion noise like a back fire but saw a flame then smoke out of engine. The engine hood was closed since the battery is located under the back seat or this could have been fatal or a serious injury. The flame must have been extinguished by the fluids? When we opened the hood after a short period, we found that their was some type of explosion in the engine. The vehicle was stationary and in my driveway”
