| Power Train problems |
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.
