2010 Audi S5 Cabriolet

THE VEHICLE WAS PURCHASED IN JANUARY OF 2018 WITH ABOUT CLOSE TO 47,000 MILES ON THE ODOMETER. CURRENTLY WITH ONLY JUST OVER 50,000 MILES THE REAR WINDSHIELD IS SEPARATING FROM THE FABRIC ROOF WHICH IN TURN HAS CAUSED WATER INFILTRATION FROM RAINFALL INTO THE REAR AND FRONT PASSENGER SIDE INTERIOR OF THE VEHICLE AS WELL AS THE TRUNK, THIS OCCURS WEATHER THE VEHICLE IS MOVING OR STATIONARY. THIS HAS CAUSED MY BACKUP CAMERA TO PERIODICALLY MALFUNCTION AND ALSO HAS RENDERED THE FRONT PASSENGER SEAT CONTROLS INOPERABLE. I TOOK IT TO THE DEALER TO HAVE ANOTHER REPAIR PERFORMED AND INFORMED THEM OF THE PROBLEM AND I WAS TOLD POINT BLANK THAT IT'S A COMMON PROBLEM AND TO NOT EVEN BOTHER TRYING TO HAVE IT REPAIRED THERE AS THE COST WOULD BE NORTH OF $6000.00. I WAS THEN GIVEN THE NUMBER OF A REPAIR SHOP THAT WOULD GIVE ME A FAR BETTER PRICE ON THE REPAIR COST AND TOLD TO GET IT DONE ASAP DUE TO THE FACT THAT THE WATER WOULD EVENTUALLY AFFECT THE "COMFORT CONTROL MODULE". I SUSPECT THAT IS THE CASE AS I HAVE STATED THE BACKUP CAMERA AND FRONT PASSENGER SEAT ARE MALFUNCTIONING. I HAVE A FOUR YEAR BUMPER TO BUMPER EXTENDED WARRANTY THAT I PURCHASED EXPLICITLY FOR POTENTIAL COSTLY ROOF REPAIRS, YET THE WARRANTY MEANS NOTHING FOR WHAT IS ESSENTIALLY A KNOWN DEFECT ON THE MANUFACTURES BEHALF. I FEEL IT IS EXTREMELY UNFAIR AS WELL AS JUST BAD CUSTOMER SERVICE FOR AUDI TO PASS THIS COST ON TO ITS CUSTOMERS WHEN THE PROBLEM IS CLEARLY A DEFECTIVE ADHESIVE. I REALLY LIKE MY CAR BUT I'M CURRENTLY PAYING FOR SOMETHING THAT I HAVE TO PARK WITH A CAR COVER UNTIL THE WEATHER IS MORE PERMITTING. SEEMS LIKE I MADE A MISTAKE CHOOSING AUDI AS THEY DON'T STAND BY THEIR PRODUCT.
