“I noticed I was getting burned on my upper hip when the seat heater was on. Thought it was the metal trim on my jeans getting too hot but discovered the seat heater had burned a hole through the seat and smelled like a fire. I turned it off and now do not use the seat heaters. It got hot in a few minutes after starting.”

After stopping the vehicle, she soon realized that the heat warmer on the seat had burned a hole in the seat and singed her sweater leaving a black mark.
