2017 AUDI S3 Structurebody Problems

I WAS DRIVING ON THE FREEWAY AT 70 MPH WHEN MY SUNROOF EXPLODED FOR NO APPARENT REASON. I WAS VERY FORTUNATE TO HAVE NOT HAD AN ACCIDENT AS IT SOUNDED LIKE A GUN HAD GONE OFF IN MY CAR. I SPOKE WITH MY INSURANCE AGENT AND HE TOLD ME TO CALL AUDI BECAUSE IT IS A KNOWN PROBLEM. AUDI DID FIX THE CAR WHICH WAS HAD A TON OF DAMAGE BECAUSE THE GLASS WENT EVERYWHERE WHEN THE SUNROOF EXPLODED HOWEVER I WAS TOLD BY A GROUP OF ENGINEERS THAT THIS COULD HAPPEN AGAIN AND THAT THEY FELT THAT IT WAS A STRUCTURAL PROBLEM WITH THE VEHICLE. I DID NOT WANT THE CAR AT THAT POINT. I SPOKE WITH AUDI OF AMERICA AND THEY RESPONDED THEY WERE DOING ME A FAVOR BY FIXING THE VEHICLE AND THEY WOULD NOT BUY IT BACK FROM ME BECAUSE ALTHOUGH THEY HAVE HAD OTHER PEOPLE...
