2019 Audi Q8

Electrical malfunction warning light. Vehicle stop and was steering wheel locked and then unlocked. Then stated ok to steer but steering was very hard. No power. Multiple systems fail warnings lights. Alternator is what they have stated. No part available. They currently (from what the service dealer states they have approximately 15 cars waiting). One dealer The issue is the in-operability of the car. Just stops which is highly worrisome.

My alternator failed with "electrical malfunction" alerts until the car decided to shut down on the highway with my newborn and wife. The bigger issue is I'm being told there is a national shortage for this part with no ETA on receiving the part and that it could be MONTHS until they receive the alternator replacement.My car is in dealership since Dec 6 2022. Today is 01.10.2023

While driving in heavy traffic on 12/23/22 the entire electrical system shut down and all power was lost. Fortunately I was not hit by another vehicle and coasted into a parking lot with no power. This is very dangerous. Per conversations with the dealership and with Audi (1/10/23), alternators on thousands of vehicles are failing (possibly due to a software issue). The vehicles are sitting on dealer lots and in driveways useless. Audi online forums confirm this as well. There are no alternators available. No recall has been issued and no warning of this unsafe situation has been made by Audi. Per the dealership, they are largely in the dark as well as there has been no meaningful communication by Audi. Someone will get hurt when their car dies on a highway. People are paying thousands for their cars to be undrivable. Audi dealers will not trade the vehicles because they are effectively worthless until repaired.

Vehicle lost all power and control while driving 45mph. First electrical system failure warning came on. Within 2 minutes the transmission slipped into neutral and 15 seconds later the vehicle lost power and I coasted to a stop. I was told by Audi dealership service that the starter generator failed. They mentioned they currently have over 20 vehicles in their shop and over 25 at their other location with the same problem. They also said over 1,000 cars nationwide had same problem and the part to repair is back ordered and no reasonable estimate of repair time.

Critical Failure - Alternator/48v Generator Issue in Audi Q8 Prestige. By now, I am well aware that the problem I'm experiencing is in the top 25 repair issues for Audi and currently there are 15,000 cars affected in the United States according to my dealer, waiting for these parts. Out of nowhere while driving on an interstate, at a high speed I got all mix of signals and the amount of time to react between the first sign that something is going wrong to the "stop operating the vehicle and pull over to the side message" and vehicle shut down, without ability to start is within just few minutes from each other. First I get a random battery error message. Battery light had popped on the dash panel. Then, system malfunction message, the whole array of different malfunctions. Noticed odd things like the auto start/stop not enabled and about 10 others error messages in regards to every system in the car. Then the speed sign sensor wasn't working, like limp mode, then the lane departure went, then the traction control system went, then the transmission something went off. I couldn't possibly make it to the dealer from that point, it was only few minutes and It told me to pull over to the side. Car would not start again, the panel wouldn't light up and only weird stuff, like windows would go up and down as I try to start the vehicle.  Had to tow vehicle to the dealer (Car is still under the original warranty). Was notified that the alternator is out and needs to be replaced. There is more to it, that part is on the back order all across the US and there is no estimate on when they're going to get it. No solution been provided and every dealership in the State has multiple vehicles awaiting for this same part.
