Open the full vehicle complaint log (all categories)Wiring harness to rear window defogger melted causing the rear window to crack and shatter. Safe lite replaced the window and recommended the harness not be reconnected. Told me it was not uncommon. Vehicle was not being used at the time. It was in my driveway when the window blew outward. Inspected by Safe lite, Reported to Liberty Mutual. No warning light, rear defogger was not in use, car was off.
REAR WINDSHIELD SHATTERED AFTER TURNING ON THE REAR DEFROSTER WHILE DRIVING ON THE HIGHWAY (ROUTE 200 ICC) AT APPROXIMATELY 60 MPH.
SUNROOF "EXPLODED" WHILE DRIVING AT LOW SPEED ON A DESOLATE ROAD. CAR WAS PARKED AT A BEACH RENTAL FOR 3 DAYS IN THE HOT SUN AND THIS WAS THE FIRST TRIP, HEARD A POPPING NOISE. SINCE THERE WERE NO VEHICLES WITHIN AT LEAST 1/2 MILE AND NO BUILDINGS WITHIN 50 YARDS DID NOT THINK THIS NOISE WAS CAUSED BY A ROAD HAZARD. LOOKED OVER THE CAR AND COULD NOT FIGURE OUT WHAT THE NOISE WAS. WHEN WE ARRIVED BACK AT THE HOUSE AND WERE SITTING ON THE DECK WE NOTICED THE SUNROOF LOOKED STRANGE, A BUBBLE IN THE CENTER . FURTHER INSPECTION FOUND THE SUNROOF SHATTERED, STILL IN PLACE. LUCKY WE HAD THE COVER DRAWN CLOSED BUT EVEN LUCKIER IT STAYED INTACT.
I WAS DRIVING ON THE HIGHWAY AND THE SUNROOF SPONTANEOUSLY EXPLODED.
