Basically, when driving, the complete cars looses power and looses all electrical power. When I was making a turn, the car lost power, transmission and steering wheel locked up. Audi power system needs to be reviewed and seemed like the Audi dealership was aware of this incident happening to other customers. Quite dangerous
On or about September 19, 2023, I was driving to work when all of a sudden, while I was driving, I received 2 error codes: 1) electrical system maintenance malfunction; and 2) vehicle starting system malfunction. I proceeded driving to work, and when I got there, no problems arose. I contacted Audi dealership to inquire about the problems, as I had only bought the vehicle maybe 2 months prior. I was informed that the vehicle cannot be driven, and I need to have it towed to the dealership immediately, as the car would more than likely breakdown and I would be stranded. I started researching the issue and discovered that this is an ongoing issue that has been happening for quite some time. Apparently, Audi has been aware of this issue for YEARS, and has failed to inform consumers or customers because they do not have the parts in stock to do a formal recall. As of this moment, my car is still at the dealer, and I am awaiting confirmation that the issue is the issue with the alternator as it relates to the battery, which is faulty. I have been informed that Audi is aware of the issue and the part has been on back order for quite some time. it could be weeks, if not months, for them to have the part needed to fix the vehicle. I do not have a loaner yet, and getting one has been an extreme pain and inconvenience, but it appears that Audi will do nothing to recall this problem due to the part shortage. I am grateful I discovered the problem when I did, and it did not cause any harm to me or anyone I know. However, there are SO many cars still on the road that this will affect, and it is a safety concern that should be looked into further.
I purchased the vehicle as a CPO, two days (1/28/23)and 200 miles later I got a warning”Electrical system malfunction”. I turned the vehicle off/on and the message reappeared every time. I spoke to the dealership they advised that the issue is know to abruptly shut down power to the vehicle at any given time even while driving. I had the vehicle towed to the Audi dealership.
