My vehicle had a complete electrical failure, when caused everything to shut down. The engine, door locks, hazards, power steering, e brake, etc. were all inoperable. On Sunday, Nov 20th, I received a yellow warning light that said, "electrical system malfunction, please contact service." I parked the car and called the dealer the following morning to ask how sever this warning was (could I drive the car or does this require a tow?). They advised me to bring the car in. While heading to the dealership, I received several other warning lights in rapid succession: electrical system malfunction, safely stop vehicle; parking aid malfunction, transmission malfunction, rear spoiler malfunction, and others. The vehicle died about 30 seconds after these warning lights appeared. …
Received an electrical malfunction - please call service warning icon on dash display. In less than one mile, I received cascading sequential warnings - including transmission and steering warnings - please pull over now. I attempted to exit the freeway on the next ramp, on the I10 Freeway in Claremont, CA on the Monte Vista Exit - but the car completely lost all power and electric (dash and all screens were dark) blocking a traffic lane. Was stranded there for over 45 Minutes until AAA/Highway Patrol were able to obtain a tow truck. Car was towed to dealer and found out it is a known issue with the 48V Alternator System in 2019 Model Year Audis. Found out alternator is unavailable due to supply chain issues and car will be out of service for at least 4 weeks! …
The alternator malfunctioned and was not available for inspection upon request My safety was put at risk as the car ceased to move while driving on high speeds on the hwy The problem has been reproduced by several other audi owners. This is a widespread issue putting multiple lives at risk The vehicle component has been inspected by the manufacture There were no malfunctions happening prior I was driving on the highway and all of a sudden, all the lights were going off on the car. alot of malfunctioning. first message was electrical system malfunction, then rear spoiler malfunction and the car ceased to begin moving. I had to park it in the merging lane and feared for my safey. I decided to call audi for a jump start. the car started but as soon as the cables were removed the car died again. i had to then call for a tow truck to take the car to the dealership. …
I had just purchased a used 2019 A7 Prestige and the next day (April 1st) while coming back from an appointment 7 miles away I had five electrically related failures in a very short time frame. The last error message was ominous so I was glad I was in my driveway when it happened. When the spoiler failure happened it automatically popped up. In addition to all these failures the AC was not working. So it seems to be an electrical system wide issue. Alas, this is a known issue with the 2019 A6, A7, and A8 models. I've posted the error messages in an online Audi owners site to spread the word and found many, many more people that have had this same issue. NOTE: The vehicle in/out mileage on the service report is incorrect. The correct numbers are 37702/37705. The car sat at the dealership for days before the repair parts arrived. …
Starter Generator failure of the 48v Mild hybrid system. This issue is very common, and has a recall on the 2019+ audi a6 (however its because of a risk of electrical fire). Car sends errors to driver as many electrical components begin to fail and fault one by one, steering wheel dynamics shifted while in motion (as steering module failed), air suspension faults occurred. The car inevitably died during operation. Was stuck inside of vehicle, the internal door handles are powered by the 48v system, they are not mechanical latches. Car stalls out when the 48v battery fails. I have had this part replaced on my car, dealership says there are 8 just like it in the past 2 months. Very common issue for Audi's. As more of these find their way on the road, each car magnifies the risks to vehicle owners and other drivers as these issues are becoming more in more common in 3 year old Audi models.
The car shut-off on three separate occasions while driving on [redacted] in Wesley Chapel, FL (twice) and once while traveling south on [redacted] in Orlando. There were multiple warning lamps and messages and I am requesting the BSG be replaced on this vehicle and the dealership refuses to replace it, although there is a manufacturer recall on this part that is a ticking time-bomb that may cause the car to shut off again while driving. When this occurs, you cannot put the car in gear and it presented a clear and present danger to the driver and their passengers. The dealership continues to try and fix other things and not the immediate and present issue of the BSG replacement. Someone please assist with getting this issue resolved and corrected.
