ON 1/12/15, WHILE MY 2005 SATURN RELAY WAS PARKED IN MY GARAGE, STARTED ON FIRE. VEHICLE WAS NOT STARTED OR GOING AT THE TIME. LAST DROVE THE VEHICLE APPROXIMATELY ONE HOUR PRIOR. IT WAS DETERMINED THAT THE CEILING COMPONENT THAT HAS THE BUTTONS TO OPEN THE BACK SLIDING DOORS, ONSTAR AND GARAGE OPENING, IS WHAT STARTED THE ELECTRICAL FIRE, WHICH BURNED A WHOLE IN MY ROOF, BURNED THE DRIVERS SIDE VISOR, WHICH IN TURN BURNED THE DRIVER SIDE SEAT AND CAR SEAT BEHIND THE DRIVER'S DOOR. GM DETERMINED IT WAS NOT THERE PROBLEM BECAUSE THE VEHICLE WAS 10 YEARS OLD AND NO OTHER CASES WERE ON FILE. A VERY VERY VERY SCARY SITUATION. *TR
