I was driving on the highway and the heated seat was turned on the passenger side of my mercedes ml 500 with my 17 daughter sitting in the seat. The car started to smell and my daughters seat felt hot to her. She tried to move her self over and burnt the palm of her hand on the side of the seat. The heated seat had been burning at a very hot temperature and was melting the leather on the seat. I immediately turned off the seat and opened the windows to help cool it off. It took 30 minutes or more for the seat to cool off in that spot. My daughter jumped to the back seat while it was still hot so that she would not get burned again.
