NHTSA Complaint #10746915 — 2004 LINCOLN TOWN CAR

2004 LINCOLN TOWN CAR CARTIER. RIDING DOWN ROAD 35 MPH ACCELERATING. WINDOWS WERE ALL UP, SUNROOF CLOSED. NEVER HAD ANY PROBLEMS PRIOR. WIFE TOUCHED SUNROOF BUTTON TO OPEN SUNROOF WHILE WINDOWS STILL CLOSED, AND BAM! THE SUNROOF EXPLODED; LUCKILY DID NOT SHATTER ONTO US BUT CRACKED IN LARGE PIECES. SCARED US BOTH BUT I KEPT CONTROL OF THE CAR UNTIL COULD PULL OVER. NO CARS IN THE AREA AROUND US. NOT AWARE OF ANY DEBRIS. A WINDSHILED REPLACEMENT COMPANY TOLD US THERE IS A HIGH INCIDENCE OF SUNROOFS EXPLODING FOR NO REASON. MY THOUGHTS ARE THAT THE SUDDEN PULLING BACK OF THE SUNROOF COVER CAUSED A BIG DIFFERENCE IN AIR PRESSURE CAUSING THE SUNROOF GLASS TO BREAK. THIS IS A SERIOUS PROBLEM NEEDING ATTN. USUALLLY I HAVE MY WINDOWS OPENED SLIGHTLY BEFORE OPENING SUNROOF..NO PRIOR PROBLEMS. ON THAT DAY, MY WIFE WAS HAPPY AS WE LEFT A BUSINESS AND OPENED THE SUNROOF BEFORE THE WINDOWS..AND THEN BAM! NEVER EXPECTED SOMETHING LIKE THIS ON A LINCOLN TOWN CAR. BUT, THE AUTO GLASS CO SAID IT IS A COMMON PROBLEM WITH SUNROOFTS. HAVE NOT YET HAD IT FIXED, WONDERING IF IT'S WORTH USING ANOTHER SUNROOF THAT MIGHT BREAK. MY CAR STILL OPERATES GOOD OTHERWISE.
