On Thanksgiving Day I received a warning on my display: "Electrical system: malfunction! Please contact Service." The next day I contacted Ellis Audi in Atlanta and was able to drive about 3 miles to take the car to them. At the end of the day they said I needed a new Alternator/Generator and the car should not be driven. They said the part was on backorder and they already had about 11 cars needing the same part. Since then they received 7 parts but now have about 20 cars on their lot requiring repair.
Starter generator/alternator problem. I was driving and suddenly got electrical malfunction issue and slowly all electronics in the car stopped working. Got the car towed to Audi service center and the service representative told me it was starter generator issue and it’s widespread. Dropped the car on 11/15/22 and still waiting for my car to be repaired.
ALTERNATOR FAILIURE (48V)
Warning appeared for electrical malfunction contact dealer. Within 15 minutes of driving to the dealer, electrical failure please pull over appeared. My antilock breaks, transmission, and finally the entire electric panel failed. The car entirely stopped while in traffic. I was unable to even turn on hazard lights. It would not turn back on. It required towing to audi dealership. I have been told by Audi the starter generator died.

Component Failed: Believed to be Starter Generator Part number 4N0-903-028-P on 11/04/2022 Cause: Ended up stranded on the side of the highway at night with no power, to include power steering and hazard flashers. Car had to be pushed out of the high way to avoid being hit by traffic. Problem is ongoing and easily reproducible. Manufacturer confirmed faulty Starter Generator on 12/15/2022 From first indicator lamp of Electrical issue to full shut down of car was about 20 minutes.
The electrical system malfunctioned driving on the busy 422 expressway. Going at 55mph. Car dash lights up warning signs like electrical system failure, transmission, brake, power steering failure and the car shuts down in the middle of the road. Steered it to the side of road. Car would not start. Had to get it towed to dealer, Car has 33000 miles. The dealer has confirmed the failure. The component has been inspected by the dealer. Could have had a serious life threatening accident posing death or injuries to self and others.
Received an electrical system malfunction on display. Took to dealer for diagnostics. Was told the starter/generator needed to be replaced and was going to cost $4000 but parts were on back order with no eta. It’s been 3 weeks with still no part and no loaner car available. This is ridiculous. This is a new car.
I experienced a total failure of the electric system in my 2019 A6. Car stopped running in the middle of the road. Had to use the tool in the trunk to manually switch the car to neutral so I could push it off the road. Car was towed to the Audi dealer in my area. Audi dealer reported the alternator is faulty. Yellow Electrical issue warning message showed up on, dashboard, then Red electrical issue message showed indicating the vehicle will shut down. Dealer reported “a bunch” of A6s 2019 and newer are expediting these issues and parts are on back order because of it.

I was driving across the George Washington Bridge towards NJ and I received warning of electrical issue, then transmission warning and the car promptly shut down, leaving my wife me stranded in the right hand lane with no shoulder. Had to call 911 to get assistance. Once at the Audi dealership I was told it is an issue with the alternator/electrical system and the car is undriveable until repaired. Unfortuately the part is back ordered and the car has been at the dealer for over three weeks. According to the service team and driver forums this is a major issue with 2019 A6, A7 and they are failing at an alarming rate. Not sure when I will receive the car back and they are not providing any loaners or rentals. This repair will cost 4,000, luckily mine is under warranty.

On November 8, 2022, I was driving my vehicle to the Audi Arlington dealership to service an "Electrical System Malfunction" alert that had recently appeared. Approximately one mile into my drive the car completely shut down while driving. This happened while I was proceeding through an urban intersection. All systems shut down on the car simultaneously, including every screen, hazard lights, engine and power steering, to name a few. I was able to coast to a stop while only partially exit the lane of traffic. As the car was entirely nonresponsive, it needed to be towed from that point to Audi Arlington. Audi Arlington determined that the issue resulted from a 48V generator.
I received a yellow alert that the auto start/stop was malfunctioning. I continued to drive 8 miles until another message was displayed on the instrument panel that stated: "electrical system malfunction" with a yellow battery icon. A few seconds later the same "electrical system malfunction" with a red battery icon appeared. I then had numerous failure warnings on other car systems such as driver assistance sensors and steering; the display screens started to flash on and off. I slowly guided the car to a complete stop and called Audi Roadside Assistance for towing to my local Audi dealer.
I was driving on highway. There was a message "Electric system malfunction" with a yellow battery icon. A few seconds late the same message " electic system malfunction" with a red battery icon then the vehicle completely stoped on the highway .
While driving on highway, had complete electrical system failure. Received red message that said “electrical system malfunction”. Car went totally black and completely shut down within 2 minutes. I had to navigate 3 lanes to pull over with completely black cockpit after car shut down. Audi service says it’s the “starter generator”. Service said there is a chance of fire with moisture ingress in the starter generator. Apparently it’s a known issue with over 60 units on back order from their supplier Continental (no promise date available). Concerned this is a serious safety issue and will cause somebody to have a crash due to car shutting down and potential for electrical fire.
