While driving the vehicle states that there was an electrical fault and to contact a service center. This was associated with a loss of drive power that made handling more difficult. A dealer advised me this morning that this is a common issue.

Massive safety liability here. My 2019 Audi A6 was on the highway traveling at 75mph on 4/25/2023 at noon when with no prior warning, all of the electrical systems started failing rapidly. In the course of 90 seconds, there was an electrical malfunction warning, quickly followed by malfunction warnings for steering, brakes, and cascading shutdowns of all systems like the transmission, ABS, Collision Warning, Lane Departure, lights, hazard warning lights, instrument screens/clusters, HVAC, windows- literally everything. A complete failure of every component and safety system while driving highspeed is extremely dangerous. Had this happened at night, I would have been bricked in the middle of the road without headlights, hazard lights, airbags, etc. The car had to be towed away to the dealership and is available for inspection. The dealer is aware of this issue and called it a 48 volt starter/ alternator issue which is apparently systemic/ widespread with 2019-21 Audi 48 volt architectures; parts are generally backordered for months. Please take note: There is an extremely high risk that someone will be killed and seriously injured as a result of this defect. The vehicle is awaiting inspection and repair at an Audi dealership. It is under extended manufacturers warranty at 50,700 miles. No other diagnostics/ inspections/ or reports have taken place yet.

Two miles from home all sorts of electrical malfunction warning -š ï¸ lights appear. Too many to list here. Then car completely stops and all electricals shut down. This happened in the middle of a very busy three lane 45mph main artery. Stuck in gear, unable to push off side of road. After ten minutes or so of cars zooming around us, it started enough to get off road to safe place. Waited 4 hours in freezing cold for tow truck. Very scary incident for my wife and me, as we are in our 70s. Towed to my local Audi dealer. The problem seems to be with the -€œStarter Alternator-€ and is a national problem with 1000s of affected owners. Was told 29 vehicles are ahead of mine for replacement and that it could be weeks before parts are available. One car family and no loaners available and there talking weeks / months to repair.

Alternator failiure (48V)

- Irvine, CA, USA

Electrical System Malfunction w/yellow battery icon...stop/start system unavailable. Vehicle deemed unsafe to drive. Towed to dealership, part on worldwide B/O...estimate several month wait for starter/alternator

- Red Lion, PA, USA

Battery light came on, called the dealer and they said don't drive and towed the car to dealer. They said need to replace Starter Generator C29. They did't have parts, so they keep my car at Audi dealer service shop for about one and hale month. I googled and look like it happened to too many people. Finally they said found the parts and charge me $2902.12. I am really concerned that part is not properly constructed or something, as even in this dealership, they said my car was sixth in one month and may more after me. They are skimming money from bad part.

Vehicle emitted multiple warnings via dashboard displays. Called dealer's service department and they advised to bring vehicle to dealership as soon as possible. They suspected the car was experiencing pending failure of the generator or alternator, which could result in an immediate loss of all electronics, posing a serious risk while driving. I attempted to drive car the 10-15 miles to the dealership the next morning and all systems failed. Dealer confirmed issue was related to the suspected generator or alternator issue.

- Columbus, OH, USA

I had a failure with the vehicle electrical system malfunction. I had multiple warnings from ABS, Power steering, Adaptive cruise control. I was on the highway doing about 70 when this happened. After about 5 mins of driving, everything powered down in the vehicle. From the dashboard to the center instrument panel. Then after that, the car cut off. Lucky I was in the right lane to pull over to the shoulder. Car never started back up. Nervous about what the dealership is going to tell me.

- Flint, MI, USA

I suffered a complete failure of the vehicle's electrical system. First, I received a warning that the electrical system malfunctioned. This warning went away after two power cycles. Two days later the warning came back and a warning that the battery level was low. I was driving the vehicle approximately 1 mile on the highway when the warning became progressively dire. First the Adaptive cruise control systems became failing one by one, adaptive lane keep, lane departure etc. Then I got yellow warnings about failures in the transmission and the engine. Finally those errors became dire that I must stop the vehicle. I next lost all electrical screens within 2-3 minutes of the cascading dire warnings just as I was pulling off the highway onto side streets. Within 30 seconds I lost power steering and most braking force. I was able to pull over into a bus stop, but with difficulty. I lost all hazard lights, all vehicle lights. I lost the ability to unlock the doors temporarily but this recovered. I could not turn the car back on, I could just hear the started struggling to turn over. None of the screens in the vehicle worked. No lights or horn worked. Thankfully this happened in the late afternoon while the sun was still out. The extreme danger posed by not having emergency lights, power steering and minimal braking capability made this an extremely scary situation. I was advised by Audi Queens that this was confirmed alternator/generator failure.

On December 16, 2022, the alternator on the vehicle failed, which prevented the battery from charging. Luckily, I had just parked the car when all the electronics shut off - otherwise I would have been driving on a busy street with the potential for an accident. The vehicle was towed that day to White Allen European Auto Group in Dayton and is still there and available for inspection. Today is Feb. 6, 2023, and they are still unable to get the required alternator parts and we don't have an ETA. To my knowledge the vehicle has only been assessed by their technician, not anyone else. There were electrical issues prior to the failure. I took the vehicle to White Allen on Nov. 22 due to warning lights for Lane Departure Warning and Lane Keeping Assist turning on and off, as well as issues with the engine shutting off at traffic lights and being unable to get the car to move without turning it completely off and back on again. When I took it to the dealership, they performed many vehicle recalls and repairs including multiple software updates, reworking the transmission wiring harness, servicing the start/stop system, airbag inspection, battery load, control module update, MMI software update, etc. I picked up the vehicle on November 30, 2022. On December 5, 2022, I had to take it back to White Allen because the bottom display screen was not functioning properly. (When starting the car, the top half of that screen was scrambled and the bottom half was dark. After driving for a while, the screen would begin functioning properly). They diagnosed it as a hardware issue with the top screen that controls the lower screen. I was told they would replace the top screen, and the parts should be available by December 29. I asked if the car is safe to drive, and they said I could continue driving it as the lower screen doesn't control anything that might be a safety issue. On December 16, the car stopped working and I had it towed back to the dealership.

Known generator problem. The entire car shut down when I was on the express way at 5:30 PM rush hour in Chicago. Luckily I was able to get over to a shoulder before the car went completely DEAD. Even the emergency flasher would not work, miracle that we didn't get killed. Can't believe Audi let people drive these cars when many have had this problem

- Deerfield, IL, USA

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.

- Simi Valley, CA, USA

Vehicle's on board system reads "Electrical Malfunction: START/STOP system malfunction. Call service". THEN this triggers a complete shutdown of the vehicle: transmission, steering, distance, and braking sensors, etc all got affected.
