Experienced alternator / generator failure while driving. Various vehicle systems starting shutting down and warning symbols were displayed. Vehicle stopped running on the highway and needed to be towed to the local Audi dealership. The sequence / progression of failure occurred over several miles with complete vehicle shutdown and stop in the middle of a busy highway intersection. Dealer confirmed it was an alternator / generator failure and it needed to be replaced. Seems to be a common occurrence with the A6 model. Dealer informed me it could be a couple of weeks to a couple of months for a repair as this item is on back order with Audi. Audi should issue an immediate recall or warning of this failure.

The rear view camera on the vehicle stops working intermittently. I have provided photographs of this to the Dealer. Their scanning of fault codes noted that the "right environmental camera faulty B127D04: Rear environmental camera faulty." The ticket also notes they found multiple sporadic faults for B127F04. Although they have admitted to finding faults with the camera, they refuse to fix this because they could not duplicate the exact behavior at the time it was in their shop. By definition, this is an intermittent issue. Audi had other model years recalled for this same issue. I believe this is a serious safety threat as one can't see things behind you and a person or vehicle could be hit. Audi is aware of this issue and is refusing to repair it under warranty.

The car literally stopped working while driving. All electrical components shut down. Unable to put the car into neutral to push it to safety. Had a hard time getting the vehicle towed because the parking break engaged somehow and we were unable to disengage it. Hazard lights did not work at all! Extremely unsafe situation to be in, especially if on a highway or expressway with vehicles traveling nearby at high speeds.

Electrical system malfunction. Car will not run

Receiving multiple electrical warnings including low battery charge, vehicle starting system, parking brake malfunction, stabilization control (ESC/ABS), parking aid malfunction, and all-wheel drive malfunction. Issue appears to be due to a common failing 48v battery alternator.

I purchased the car new around June 2020 and it currently has just under 26,000 miles on it. Earlier this week while driving the car, an electrical malfunction warning appeared on the dashboard display. The first dealership I contacted did not deem it serious and set me up for an appointment over a month away. The second dealership I called had me tow the car in right away as the thought was my alternator had failed. A call back later that afternoon confirmed the alternator did in fact fail. That dealer also indicated that the wait time for a replacement was several months away. This seems to indicate much larger problems with this part as alternators are fairly common and very necessary components.

While driving to work, received notification of "Electrical System Malfunction, contact service immediately". I contacted Audi. They advised me to either bring the vehicle in or have it towed. I drove to Audi that afternoon. While driving to the service facility, the warning changed and told me to pull over immediately. As I was close to the dealership, I continue to drive and was able to make it to the dealership. I was informed by the service manager that the car could have shut down at any time and I would have lost complete control of steering and brakes. This is apparently a well-known problem with the 48 V generator. It will be a 2-month wait until I can have the generator replaced. Given that the electrical systems could have shut down at any time, this is a safety issue.

Vehicle reports Electric Malfunction and then suddenly start getting all warnings like all controls (like steering etc) disabled and vehicle stalled in the middle of the road. Had to get it towed and taken to dealership. They do not have a fix for this problem and no estimates on how long it will take to fix the issue and get the car back.

The contact owns a 2020 Audi A6. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power. The brake, transmission, and several other unknown warning lights were illuminated. Additionally, the windows inadvertently rolled up and down while driving. The vehicle was towed to the dealer where it was diagnosed that the driver's and passenger's side rear seats sustained water damage, which caused an unknown electrical system component to malfunction. The dealer informed the contact that the manufacturer declined the replacement part. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 22,000.

Gateway unit that is located under the rear seat has an inadequate insulation and is susceptible to liquid exposure and electrical failure. A liquid penetrated the rear seat and short-circuit the gateway while vehicle was moving resulting in a near-accident by shutting down power steering, brakes, and many of the car's systems. Failure messages began appearing and vehicle was unresponsive to driver actions. Emergency blinkers were not working at the tail lights which is a critical safety hazard for a disabled vehicle on the road. Dealer confirmed gateway unit failure due to the water exposure and recommended the replacement of the unit. Vehicle had no warning lights or messages prior to the incident.

On more that one occasion, after starting the car and putting the car in drive, the display continues to show that the car is in PARK. I can drive several hundred feet with the display showing PARK. Then the display will go totally dark and, after several seconds, it will show that the car is in DRIVE.

Various components and system malfunctioned. Vehicle is in dealership for 3rd time on electrical/software/hardware troubles, SOS module. Yes, the vehicle is available for inspection. The car stopped me on a major highway thinking that I was not available "Emergency Assist, Driver take over the wheel" when I had both hands on the wheel, going straight and was fully in control of the vehicle. The car slowed down from 70 mph and the trailing truck behind me almost rear ended me. Yes, the problem has been confirmed by the dealer. The vehicle and components are being inspected/serviced at the Fort Collins Audi dealer. Yes, warning messages as well as the vehicle pumping on the break and jerking the seat belt. These started in Jun 2021 at 1400 miles and continued to the time I turned in the vehicle on 19 Oct 2021 at approx 13500 miles. I am attaching an 11 page documentation of dates, times and mileage of each incident that the vehicle's computer systems are not functioning properly and the safety features are not reliable or make the driver feel safe with bogus warnings, or warnings that are erroneous.
