MY VEHICLE WAS STATIONARY PARKED IN MY DRIVE WAY, AS I CAME OUT FROM MY HOUSE (AROUND 8PM) I NOTICED THE WINDOWS LOOKED VERY DARK AND I COULD NOT SEE IN THE TRUCK. I OPENED THE DRIVER DOOR AND WAS OVERWHELMED WITH A DENSE ELECTRICAL BURN SMELL COMING FROM THE CAB OF THE TRUCK. THE FIRE LOOKED LIKE IT STAYED NEAR THE ROOF OF THE CAB AND ORIGINATE FROM BOTH CENTER PODIUM SEAT BELT MOUNTS. BOTH SEAT BELT MOUNTS ATTACHED TO THE REAR DOORS FOR THE FRONT DRIVER AND PASSENGER HAD EXTREME AMOUNTS OF HEAT ORIGINATING FROM THAT AREA. THE PLASTIC AROUND BOTH THESE AREAS HAS COMPLETELY MELTED AWAY AND CAUGHT FIRE TO NEARBY WORK ITEMS ON THE BACKSEAT BENCH. SMOKE DAMAGED EVERYTHING INSIDE THE CAB OF THE VEHICLE. SMOKE COVERED ALL WINDOWS AND EVERYTHING INSIDE THE CAB. VEHICLE ELECTRIC SYSTEM STILL FUNCTIONS FOR LOCKING AND UNLOCKING DOORS. I HAVE NOT ATTEMPTED TO START VEHICLE, SMOKE SMELL AND DAMAGE TO INTENSE TO ENTER VEHICLE. FOUND AN ARTICLE ON TOURQENEWS.COM ABOUT RELATED CASES OF FORD F 150 SEAT BELTS ELECTRICAL MECHANISM CATCHING FIRE FROM YEARS BETWEEN 2015-2018. NO RECALL ISSUED YET THAT I KNOW OF. WILL ATTACH ARTICLE IF I CAN.
