I PARKED THE CAR 6/12/19 WED THAT EVENING AND EVERYTHING SEEMED OK. AT 1030AM THE NEXT DAY, 6/13/19, I TRIED TO USE ELECTRIC KEY TO UNLOCK TO GO TO WORK AND REALIZED IT WOULDN'T UNLOCK SO I NOTICED BLACK SOOT ABOVE DRIVER WINDOW AND TRIED MANUAL KEY TO UNLOCK. I COULD BARELY CRACK TO SEE THE SEAT EXPLODED ON DRIVERS SIDE. CALLED 911 AND FIREMEN AND POLITICS ARRIVED. THE FIREMAN COMPLETELY OPENED THE DOOR AND AFTER EXAMINE SAID THE HEATED SEAT DEVICE HAD EXPLODED OR MALFUNCTION AND THE BACK OF SEAT WAS BLOWN IN A RECLINED TO THE BACK SEAT POSITION AND ALL WINDOWS COMPLETELY COVERED IN SOOT, AND A VERY STRONG ELECTRICAL FIRE SMELLL WAS OBSERVED. BELOW ARE PHOTOS OF CAR WHICH WAS PARKED AND IT HAPPENED DURING THE NIGHT.
