Due to the cold weather I turned on the driver heated seat. I suddenly started feeling it extremely hot, I was wearing a quilted sweater. When I arrived at my work a coworker noticed that my sweater was burned from the back, it had a hole. Then I saw that the seat was burnt due to the extreme heat, the seat melted, it had three small holes and one bigger. I am just concerned that my car couldve burned while I was driving, due to the malfunction of the heated seats.
