Audi A8 NWB Engine problems by year

My car was schedule for the 21H7 recall. I received 2 letters this year to have the recall work done. Audi of Pittsburgh's only available date was 12/08/22. I took the car in and later that day I got a call stating the recall was done back in March of this year. I told them it was not. Later I got a call saying it was done in April of 2019.

Recall for turbo internals, but nothing done to remedy problem . Second issue in leaking suspension parts, which the dealership let problem continue, until warranty up.

There was no warning and I had my 2 young kids in the car and it could have caused an accident. This was dangerous for myself and other motorists. I use this vehicle as a daily driver and this should not happen. I have not had it repaired yet but I can only imagine it will costs thousands of dollars.

Car stalls unexpectedly when driving on city streets or highway. Cause due to turbo issues

Was driving on the highway for 2 hours, slowed down to exit to a gas station, once on the route car shut down, all systems inoperative steering and brakes soon harden could securely stop at gas station with impulse. Car could not be turned on again easily, and in my drive to the closest hotel (2 mniles) car will shut down if not constantly accelerated. Dealer told me two turbos needed to be replaced. Car had 45k miles, less than one month off cpo warranty (i.E., Perfectly maintained).
