NHTSA Complaint #10904461 — 2007 BMW 328XI

I WAS ON A WELL-PAVED ROAD, APPROACHING A HIGHWAY ON-RAMP, TRAVELLING STRAIGHT AT ABOUT 40MPH, AND MY SUNROOF SPONTANEOUSLY EXPLODED. I HAD BEEN ON THE ROAD MAYBE 5 MINUTES, IT WAS SUNNY AND APPROXIMATELY 80 DEGREES OUT, THERE WAS NO SUDDEN CHANGE IN TEMPERATURE AND THERE WAS NO IMPACT FROM FLYING DEBRIS, POT HOLES, OTHER VEHICLES ETC. BOTH MY SUNROOF AND VISOR WERE BOTH CLOSED AT THE TIME. I HEARD AN EXTREMELY LOUD BANG, SIMILAR TO A GUNSHOT BUT NOT AS LOUD, I CHECKED MY MIRRORS AND DIDN'T SEE ANYTHING. I THEN OPENED THE VISOR TO MY SUNROOF AND GLASS RAINED DOWN. I IMMEDIATELY CLOSED MY VISOR AND PROCEEDED TO A SAFE SECTION OF THE ROAD WHERE I CULL PULL OFF AND INSPECT THE EXTERIOR OF MY CAR. FROM THE EXTERIOR, IT LOOKED LIKE AN EXPLOSION HAD OCCURRED INSIDE THE VEHICLE AS THE GLASS WAS ANGLED UP AND OUT, WAS COMPLETELY SHATTERED AND HAD SEVERAL LARGE PIECES MISSING. I FILED A REPORT WITH BMW AS SOON AS THE OFFICES REOPENED AND AM WAITING ON FURTHER INFORMATION. FROM WHAT I CAN SEE, THIS IS NOT THE FIRST INSTANCE OF THIS OCCURRING WITH BMW VEHICLES.
