2019 AUDI Q3 Engine Problems

After multiple attempts to have my 2019 Audi Q3 repaired the vehicle is still sitting at Audi of Columbia with the following issues (leaking water, drainage system is compromised, mold in the roof lining, sunroof is leaking).

THE CAR HAD AUTOMATICALLY SHUT OFF SEVERAL TIMES. THIS PAST TIME (WHICH IS WHY I'M REPORTING IT) I WAS DRIVING TO MY OFFICE THAT IS LESS THAN 1.5 MILES FROM HOUSE AND I WAS GOING THROUGH A 4 WAY INTERSECTION AND THE CAR COMPLETED SHUT OFF, STEERING WHEEL LOCKED , BRAKE AND ACCELERATOR PEDALS LOCKED. IT TOOK SEVERAL MINUTES FOR ME TO GET THE CAR STARTED AGAIN.AND I ALMOST GOT HIT FROM ONCOMING VEHICLES. IT IS A BRAND NEW CAR WITH 6,000 MILES ON IT. I HAD IT TOWED TO AUDI DEALERSHIP BECAUSE I WAS NOT COMFORTABLE DRIVING THE VEHICLE. I WAS INFORMED LATER THAT DAY BY AUDI THAT IT IS A KNOWN ISSUE WITH THE CAR BUT THEY WILL NOT HAVE THE PART TO FIX IT FOR 2 MONTHS. THEY STATE AUDI SAID IT'S NOT A SAFETY ISSUE. IF YOUR CAR SHUTS OFF RANDOMLY AND YOUR ON THE HIGHWAY...
