2017 AUDI A3 CABRIOLET Electrical System Problems

I PURCHASED THIS VEHICLE FOR MY 18 YEAR OLD DAUGHTER AS A PARENT YOU WANT TO HAVE YOU CHILD AS SAFE AS POSSIBLE.THE VEHICLE IS ANYTHING BUT SAFE. AS A MATTER OF FACT IT'S AN ACCIDENT WAITING TO HAPPEN. OR WORST A FATALITY.THE VEHICLE WHILE DRIVING JUST TURNS OFF. IT WASN'T EVEN A MONTH INTO OWNING THE BRAND NEW VEHICLE THAT ISSUES STARTED TO ARISE. WHILE REVERSING OUT OF A PARKING SPOT, THE VEHICLE STOPPED WITHOUT ANY WARNING.ABOUT 4 WEEKS LATER, WHILE ENTERING THE EXPRESSWAY,ONCE AGAIN THE VEHICLE WITHOUT WARNING COMPLETELY TURN OFF. BY A MIRACLE OF GOD MY DAUGHTER DID NOT GET INTO AN ACCIDENT. A VERY DANGEROUS SITUATION AS MANY OTHER VEHICLES ARE DRIVING AT HIGH SPEEDS. ON 3/31/17 THE VEHICLE WAS TAKE TO THE COLLECTION,WHERE THEY COULD NOT TELL ME EXACTLY WHAT THE PROBLEM WAS SINCE THEY THEMSELVES HAD NO CLUE. BUT THEY DID TELL ME THAT...
