Open the full vehicle complaint log (all categories)I RECENTLY PURCHASED A 2008 AUDI A4 3.2L CABRIOLET. ABOUT 4 WEEKS AGO, WHILE DRIVING, I NOTICED IT SOUNDED LIKE ONE OF MY WINDOWS WAS OPEN, AS I COULD HEAR OTHER VEHICLES DRIVING BY LOUDER THAN NORMAL. I TRIED ROLLING UP THE WINDOWS SEVERAL TIMES WITH NO CHANGE IN SOUND. ALL WINDOWS WERE UP. ONCE I ARRIVED AT HOME, I DID A WALK AROUND INSPECTION OF MY CAR, AND SAW THAT MY REAR WINDOW WAS DETACHED FROM THE CONVERTIBLE TOP. THERE WAS NO DAMAGE TO THE WINDOW OR CONVERTIBLE TOP, JUST THE GLUE/SEALANT HAD WORN OFF (AFTER ONLY 2 YEARS!). THERE WAS VERY LITTLE ADHESIVE LEFT ON THE TOP-CENTER OF THE WINDOW. IT WAS HANGING ON BY ABOUT A 2" STRIP OF ADHESIVE. THIS TRIP HOME WAS 26 MILES ON THE HIGHWAY AT SPEEDS OF >55MPH. HAD THERE BEEN A LITTLE MORE WIND OR THE NEED FOR EVASIVE MANEUVERS, THIS WINDOW COULD HAVE EASILY DETACHED FULLY, AND HIT OTHER VEHICLES. AFTER DOING RESEARCH ONLINE, THIS IS A COMMON PROBLEM FOR THIS VEHICLE. THE ONLY AUDI DEALERSHIP ON ISLAND COULDN'T GET ME IN FOR >2 WEEKS. DUE TO NOT WANTING RAIN DAMAGE, OR THE WINDOW TO CAUSE A MVC, I PURCHASED SOME SILICONE ADHESIVE/SEALANT AND PUT IT BACK ON MYSELF. I CAN NO LONGER PUT MY TOP DOWN WITHOUT THE WINDOW SEPARATING AGAIN. *TR
DRIVING ON INTERSTATE, LIGHT TRAFFIC, 65MPH, 5PM, GOOD BUT WET CONDITIONS. SUN ROOF EXPLODED! VERY VERY LOUD. BASEBALL SIZED HOLE IN EXACT MIDDLE OF SUN ROOF WITH GLASS PUSHED OUTWARD (BOWL SHAPED). NO IMPACT WITH ROCKS OR ANYTHING ELSE NEAR BY. NO CAR IN FRONT BUT A CAR IN NEXT LANE. DEALER HAD NOT HEARD OF SUCH A PROBLEM. COST WAS ABOUT $800 FOR REPLACEMENT WHICH WARRANTY APPARENTLY DID NOT COVER ACCORDING TO DEALER. *TR
