“I drove the car a mile to the store and a mile back and when I was walking away you could see a spark and then a minute later another one and another until then the car started smoking and within 4 minutes the car was engulfed in flames. My security cameras caught the whole thing on tape. We tried our best to contain the fire but it took the fire department to put it out.”

“I had taken a longer road trip, and was on my way back, about a quarter of the way when we stopped for dinner. I parked, and everything was usual. A couple minutes later, I went to move the car, and while I was waiting in a drive-thru line, I see smoke billowing out from under the hood and I smell a burning smell. I parked the car back where it had been, and, thinking it was a coolant issue, opened the hood to let the engine cool down, and left my passengers with the car and walked across the street to buy some coolant. …”
