2018 AUDI A3 Engine Problems

Hello, I dropped my car off at Audi and Dominion in San Antonio Texas on Thursday July 10th for a repair this was a recall for the fuel pump system in something in the mechatronic controls. They had my car until Saturday I was informed that the repairs were done under warranty. Then on Saturday July 19th as I began to drive the vehicle a alert for my transmission malfunction appeared on my dashboard and I Lost first gear. I had my car taken to Audi on Dominion where I was informed by several service staff that this is a common malfunction after the last software update that was done the week prior and that it could take up to 48 hours to do the repair and recall warranty work on my vehicle. Audi on Dominion has had my vehicle for 5 days and has not given me an answer...

I was driving on the freeway at 60 mph when I received a warning code of a transmission problem. The code said the car was driveable but I should take it in for service. About 1-2 minutes after that the car lost all power. Unfortunately I broke down in the left lane in a construction zone without a shoulder. The state patrol had to temporarily shut down all three lanes of the highway to push me out of the traffic lane I was blocking.

The car was up to date on all recommended service, had been acting normally until the moment it failed, had not given me any warnings and is only 6 years old. I had the car towed to the dealer and the dealer reported that the Mechatronic unit (transmission computer) failed....

OFTEN THE CAR SPONTANEOUSLY RESPONDS WITHIN SECONDS IF IT HAS NOT STALLED, BUT RECENTLY NOW IT STALLS AND SPUTTERS, THEN NEEDS TO BE RESTARTED. I WAS PULLING OUT OF A PARKING LOT INTO TRAFFIC WITH SAFE DISTANCE, WHEN THE CAR BECAME "DORMANT" AND STALLED. LUCKILY, THERE WAS A CENTER LANE THAT I COULD COAST INTO TO AVOID CAUSING A SERIOUS ACCIDENT. UPON RESTARTING THE VEHICLE, THE SCREEN DISPLAYED "START/STOP SYSTEM: MALFUNCTION". I SHUT OFF THE SYSTEM AND DROVE HOME. THE NEXT MORNING, THE CAR DID THE SAME EXACT THING- HAD JUST STARTED UP THE CAR AND BEGAN DRIVING- AND IT LOST ALL POWER TO THE GAS PEDAL/WE ALMOST CAME TO A COMPLETE STOP- BUT THE CAR WAS STILL RUNNING, THEN IT QUICKLY RESET ITSELF.
