2015 AUDI A3 CABRIOLET Structurebody Problems

I NOTICED A SMALL CRACK ON THE SUNROOF GUIDE RAIL BEZEL IN THE FRONT CORNER OF SUN ROOF ON THE DRIVERS SIDE ON THE BLACK TRIM PART ABOUT A WEEK AGO. TODAY I NOTICED THE CRACK TO BE ABOUT 2" LONG AND THE BLACK TRIM SEPARATED ALLOWING WATER TO GO UNDERNEATH THE ROOF OF THE CAR. I ALSO NOTICED TODAY THE PASSENGER SIDE STARTING TO CRACK AS WELL. NEVER SAW THIS BEFORE ON THE CAR UNTIL ABOUT A WEEK AGO. CAR HAS NEVER BEEN IN AN ACCIDENT. THE CAR HAS 18,000 MILES ON IT AND IS GARAGE KEPT, NEVER DRIVEN IN TEMPERATURES UNDER 30 DEGREES F.

POOR PAINT. HEADLIGHTS AND PAINT CHIP AND HAVE SMALL DEFECTS CAUSED EASILY FROM NORMAL TRAVEL.

I WAS DRIVING AND SUDDENLY HEARD A LOUD EXPLOSION ON THE TOP OF ME, THEN I SAW A MY SUNROOF CRACKED. I STOPPED TO CHECK ON IT AND I CONTINUED DRIVING FOR ABOUT A MILE UNTIL PART OF THE SUNROOF BLEW OFF AND HIT OTHER CARS. NOTHING HIT THE GLASS FOR IT TO BRAKE, IT SIMPLY EXPLODED FROM THE INSIDE OUT (PRESSURE-LIKE EXPLOSION). DEALER SAYS IT HAS NO RECALL AT THE MOMENT FOR MY VEHICLE BUT WHILE DOING MY RESEARCH, I FOUND OUT THAT AUDI CAR OWNERS HAVE HAD THE EXACT SAME PROBLEM IN THE PAST WITH NO RESOLUTION YET. CHASSIS MIGHT CAUSE EXTRA TENSION ON SUNROOF CREATING IT TO EXPLODE, OR INSIDE PRESSURE IS TOO STRONG FOR THE GLASS TO RESIST. SUNROOF AND WINDOWS WERE UP (CLOSED) AT THE TIME OF THE INCIDENT.
