HEATED SEATS WERE GETTING HOTTER THE PAST COUPLE OF USES...UNTIL TODAY WHEN I WARMED UP THE CAR (APPROXIMATELY 3 MINUTES). I WAS PUTTING MY DAUGHTER IN HER SAFETY SEAT IN THE REAR PASSENGER SIDE. WHEN I OPENED THE DOOR, THE CABIN OF THE VEHICLE WAS FILLED WITH THICK WHITE SMOKE. I REMOVED MY DAUGHTER AND PROCEED TO ASCERTAIN WHERE THE SMOKE WAS COMING FROM. THERE WAS A SWIRLING FUNNEL OF SMOKE COMING FROM THE FRONT DRIVER SIDE. I OPENED THE DRIVER SIDE DOOR AND OBSERVED THE DRIVER SEAT LEATHER BURNING (FIZZLING AMBER FIRE). I LOOKED OVER TO THE SEAT WARMER LIGHT AND IT WAS ON. I TURNED IT OFF AND HAD TO PUT OUT THE FIRE BY BATTING MY HANDS AGAINST THE FIRE WHILE HOLDING MY DAUGHTER IN THE OTHER. THE FIRE LEFT MY HANDS CHARRED AND THE ENTIRE INTERIOR OF THE CAR SMELLING LIKE SMOKE. *TR
