“I turned on the seat warmer and a minute later I smell something burning and I look to the side and there was smoke coming out of my jeans and I got out of the car and I see smoke coming out the drivers side seat. I immediately turned off the car and it open a small hole in the drivers seat.”
NHTSA complaint #10496337, filed 2013-02, 54,400 miles“My wife was driving our mercedes R350 with two of our children and noticed a burning smell in the vehicle. 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. She turned off the seat warmer to avoid any further issues, including the potential of a fire or an injury to her.
