The car displayed a warning that the electrical system had a fault and to contact service. I then contacted service and they said to drive it to the dealer as it sounded like a known issue with the generator/starter and 48V system. On the way to the dealership, the warnings continued and then various systems began shutting down, including the steering and the transmission. I was going at a relatively slow speed on a side street at the time, which was fortunate, as the car locked up all four wheels and had no steering and the engine quit. Thankfully it was a side street. If this was a major street or highway, it quite likely could have caused a serious accident or injury. In contacting Audi USA, they do not have parts available to fix this issue, and the dealership confirmed that they are unable to fix the car at this time.

It appears that the 48v hybrid alternator failed. The vehicle completely shut down/lost all power while driving 50 mph on busy road. Almost rear ended while trying to coast to a stop. Low battery light came on the day before. The day it failed I was driving it to the dealership.

While I was driving, the vehicle gave an electrical system malfunction warning. When I stopped and restarted the vehicle, the car reluctantly started with delays and a check engine light. I had to tow the car to the dealership. Upon inspection, they determined it is a generator issue, much like many other owners of 2019+ model year of Audi's. They do not have an ETA on the replacement part, and thus the car will be out of commission for weeks to months. I am lucky, as many other people who have experienced this problem have had their car completely die on them in the middle of driving. This is a potentially dangerous safety hazard, and an enormous inconvenience, as any Audi owner with this generator issue will not have their car for weeks to months.

The starter/generator (formerly known as alternator) of our A6 3.0 needs to be replaced, the part is back-ordered for approximately 60 to 90 days. The yellow indicator light goes on and then the car shuts off. It happens without warning and is incredibly dangerous.
