Open the full vehicle complaint log (all categories)Windshield seal bond at top failed resulting in loose front windshield not being attached to the body. This is leaking water and leading to poor visibility that is dangerous but more concerning is the detachment of the window from the body. This would be extremely dangerous in a collision. The car is parked at this time due to being dangerous to drive.
WHILE DRIVING ALONG THE INTERSTATE IN SOUTHERN CALIFORNIA, AT ABOUT 70MPH, THE SUNROOF OF MY 2011 VOLVO C30 SPONTANEOUSLY EXPLODED. THERE WAS NO PREVIOUS INDICATION OF ANY FAULTS WITH THE SUNROOF SYSTEM AND IT WAS CLOSED AT THE TIME OF THE EXPLOSION. I WAS NOT DRIVING IN TRAFFIC OR IN THE VICINITY OF LARGE VEHICLES THAT COULD HAVE KICKED UP DEBRIS. I ALSO HAD NOT PASSED UNDER ANY OVERPASSES. FROM MY RESEARCH ONLINE, THERE DOES NOT APPEAR TO BE A RECALL ON ANY VOLVO SUNROOFS. THE LOCAL VOLVO DEALER IN SAN DIEGO HAS TOLD ME THAT THE REPAIR WILL NOT BE COVERED UNDER WARRANTY SINCE THEY COULD NOT DETERMINE THE CAUSE OF THE EXPLOSION. THE OUT OF POCKET REPAIR COSTS ARE ESTIMATED AT $980. IT DOES NOT SEEM THAT THE LOCAL DEALER IS INTERESTED IN INVESTIGATING THIS INCIDENT, BUT THEY DID POINT OUT THAT THEY HAVE SEEN SIMILAR EXPLOSIONS ON OTHER MODEL VOLVO BEFORE.
THE WINDSHIELDS ON THESE CARS MAZDA 3 AND THE FORD FOCUS ALL SAME PLATFORM ARE KNOWN TO HAVE A BONDING DEFECT WHEN THEY WERE BUILT. THIS SHOULD HAVE BEEN A RECALL FOR SAFETY.
