WHILE RETURNING FROM CHURCH TODAY MY LEFT BUTTOCKS GOT HOT...HAD THE A/C ON SINCE IT WAS WARM OUTSIDE. REACHED BACK AND IT WAS VERY HOT...THEN SMELLED SMOKE. WAS ABLE TO PULL OVER QUICKLY AND STOP CAR. THE LEATHER SEAT WAS SMOKING AND HAD BURNED A HOLE ABOUT THE SIZE OF A NICKEL AND THROUGH TO MY PANTS. DISCOVERED THE SEAT HEATER WAS ON HIGH...HAVE NO IDEA HOW IT GOT TURNED ON. NICE HOLE IN PANTS AND LEATHER SEAT. ANY REPORTS OF THIS FROM OTHER BMW OWNERS? *TR
