When started up on 11/17/22, multiple warning lights came on in rapid sequence advising of an electrical system & battery malfunction. Warning was to not drive the vehicle and contact service. I shut off the vehicle and re-started it. The same warnings were displayed. I was about 0. 8 mile from the dealer so I attempted to drive it to their location. On the way, the warnings continued to show. After about 0. 6 miles, the transmission fully disengaged from the engine. I coasted to the side of the street, shut off the vehicle, re-started it (same warnings showed) but the transmission was reset and worked. I drove to the dealership where my Audi mechanic knew exactly what the issue is--there is a huge problem with a continental-supplied 48v belt starter/generator that needs to be replaced. However, none are available and won't be available until sometime in q1 2023 or later. The replacement part is backordered with every Audi dealership experiencing this issue with multiple models in the my's of 2018 through 2023. Had this issue occurred on an interstate highway (complete loss of transmission), I could have been rear-ended by a vehicle following me. In a multi-lane situation, coasting to the either side of the highway may not have been possible. . . . Again, creating a very hazardous situation for me and other vehicles. I tried to attach the Audi technical service bulletin showing the extent of the issue within Audi's model range and model years but it would not upload to your site. The TSB is 27 22 45 2058831/5 September 27, 2022. This is issue is leaving thousands of Audi vehicles unsafe and un-driveable. I urge you to act immediately to force Audi to recall these vehicles.

Engine turbocharger experience catastrophic damage, engine stalled, power steering was disrupted.

The car was running rough for a couple weeks; hesitant to accelerate, failed to start multiple times and idled rough. One day I was coming home from my hour long commute, I put the car in reverse in my driveway and the car started bucking so badly that it became un-drivable. At this point we had to get the car towed on a flatbed an hour away to the nearest dealership and this is when we discovered that the turbos had gone bad. There was no check engine light or any indication before it just failed. I am active duty in the united states coast guard and being without a car is not an option. Because of the shipping delay and waiting for the turbos to come from germany, I was without my car for two weeks. I was loaned a vehicle but I had to rent a car for one day in between. We have been told by Audi dealerships for years that this was a known problem and to expect this $10,000 repair.

Turbochargers failure due to clogged oil screen. Had to replace both turbocharger with new units and replaced oil screen with updated version.

Turbochargers can failure with no warning while driving which is a severe safety hazard.

While driving, the car started to run rough and wouldn't idle when I came to a stop. It became very hard to start, especially when hot. While the car was in for recall work it was diagnosed with bad turbochargers. Quoted over $10k in repairs.

It if very well known issue for 4. 0tt v8 Audi engine, there is pour oil supply to turbos which causing them to fail. After an hour of cruising on highway car would choke on idle, difficult to even start. Audi dealer diagnosed turbo failure without underline cause. 10k dollars repair every 20-50k miles is unreasonable due to fact that oil separator, oil strainer, seals and coolant lines have been identified to be defective and updated by manufacturer (Audi).

Car has 3 bent rims and a broken motor mount carmax will try to say they fixed rims and the motor mount is fine.
