I was slowing down to stop at a traffic light when a message was displayed on the instrument panel that says "Electrical System Malfunction" with a yellow battery icon. A few seconds later the same "Electrical System Malfunction" with a red battery icon. Then the vehicle came to a complete stop and was inoperable. There was almo smoke coming from the hood near the positive battery terminal. The smoke had an electrical smell to it. I had no opportunity to pull over and was stuck in the middle of a very busy road right at the stop line of the traffic light. My family and I had to exit the vehicle with traffic on both sides of us and get to the side of the road safely. There was no prior indication that there was a problem, this happened all within about 5-10 seconds and I had no time to try and pull over to safety. …
The contact owns a 2019 Audi A6. The contact stated that while operating the vehicle, the warning message "electrical malfunction" suddenly displayed along with a red battery icon. After turning off and restarting the vehicle, the message remained displayed, but the battery icon changed to yellow. The vehicle was taken to the local dealer who diagnosed that the starter generator was faulty and needed to be replaced; however, the part was on backorder and would not be available for several months. The manufacturer was not yet contacted. The failure mileage was 42,000. The contact stated that the replacement part is now available but they have to wait for the installation. Audi has been notified and is aware of the issues.

Electrical fault dash warnings (steering, transmission, braking and many other things too numerous to mention came on while driving the car and it went into limp mode and forced the car to stop and would not restart. The car had to be towed to the dealership where they diagnosed the problem to be the "alternator" which is more accurately what is known as the "belt starter generator" BSG. The BSG runs the start stop feature of the car and charges the mild hybrid 48v battery system that runs many of the critical features of the vehicle. They do not have the part in stock and do not know how long it will take to get in. I understand that there is NOT an upgraded part available that will fix this issue, only the same part that they are continuing to put on all of the V6 engine models since 2019 to today. The A6,7 and A8 and Q5,7 and Q8 models in particular are being affected. …
This is my SECOND entry/complaint regarding the same EXTREMELY DANGEROUS steering malfunction. While driving my 2019 A6 (this time alone) in heavy rain the same warning message was displayed. The warning stated: steering malfunction, please stop the vehicle!. At which point the power steering locked-up & the engine powered down. As a result, I was unable to steer the vehicle. One again I was able to exit the highway safely. Being close to home with only a few turns, I was able to "limp" the car home, parked in my driveway and contacted Audi. Currently it's at Nyack Audi awaiting service on Monday 9/11. This is a huge safety issue and needs to be addressed. Doing a bit of online research & reading countless Audi blogs, I found out this to be a common issue with other Audis while driving in the rain. Fist time this occurred was 6/16/22, driving a 2016 S6. …

Multiple warnings indicating to contact dealer (Lane departure, adaptive cruise control, collision avoidance, etc) then 1 minute later transmission failure and engine failure imminent.... pull over immediately and contact dealer. I turned into a road off main highway within a minute of the last two warnings and as I turned, my center MMI went blank then my electronic dash went blank, transmission went into neutral and the engine died all within a few seconds. Fortunately I was able to coast to a stop in the parking lot. Flatbed towed to dealer who stated most likely the generator between the lithium battery bank and gas engine failed. They have seen several in this year for A6 and A7's with mild hybrid engines. I'm lucky to be in low volume traffic as there was no power to indicate to drivers around me that my engine quit and not even turn signals worked.
