2021 Audi A8LElectrical system

See attached document for complaint. I took my 2021 AUDI A8 to Audi Rockville located at 1125 Rockville Pike; Rockville, MD 20852 on July 18 to fix the recall. After waiting for 2 hours at the dealership, they told me they must go to BestBuy to buy a USB stick and asked if we could re-schedule which we did. I then came back on September 30, and again after 2 hours of waiting, they told me the USB port in the car is not working and that I must pay over $1000 to replace the USB Port so that they can perform the...

recall. As such we could not get the update done. I followed up with Audi North America Headquarters in Michigan, and they basically told me the same thing that the dealer told me. This issue is very disappointing for two reasons: 1) How can a $100,000+ car be updated using a USB. I have never used the USB port until this Recall. 2) If Audi has no other way to take care of the recall, then Audi should take responsibility for replacing the USB port. The dealership said the USB Port is not part of the recall and it is not under warranty. I am driving a car that is under NHTSA recall violation and Audi should take responsibility for updating the software either by replacing the USB port or perhaps through Wi-Fi. Can NHTSA file a complaint with Audi North America?

power was failing and stalling. In addition, the stall was impacting the car battery. We had difficulty steering the car and controlling the direction of the car and getting the car to the side of the road. Once we were at the side of the road, we looked up the closest Audi dealership, fortunately we were 3.9 miles away from Audi Dealership in Van Nuys, CA. Once on the side of the road the vehicle initially would not restart the engine stalling had drained the battery. We waited on the side of the road for approx.. 40 minutes and were able to restart the car and drive with much difficulty to the Keys Audi Van Nuys dealership. We were able to barely get into the dealership parking lot when the car completely stalled, we went in and met with the service manager. We explained what had happened, and with the service teams help we pushed the vehicle into a bay to get reviewed. I have purchased eight (8) Audi's over the past years for me and my wife. The service manager promised to review the problem. Typically, Audi service will give you a vehicle to drive but the had no vehicles available, so they told us they would take us to a rental car company and cover the cost of the vehicle except for the insurance on rental car, which we had to pickup at a rate of $ 35.00 per day. As we were on a work trip we had to hustle to our customers as we had a meeting scheduled for 2:30 PM at Manna Beverage in Anaheim, CA. We went to our meeting and then returned to the Audi Dealership in Van Nuys. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

dealership and they changed out the 48V battery in the trunk. They also ordered an alternator but did not install it because it start it back up. A couple weeks later (9/25/2021) the same thing happened at a stop sign as I was slowing down but not at a complete stop and hit the gas and the battery light came back on. That light means the battery is disconnected from the engine and once the power runs out, it will shut down again. So I took it straight to the dealership and left it there until they can take a look at it. It's at the dealership now. There seems to be a flaw in the (stop/go)system of the vehicle when the engine wants to turn off at a stop and when to restart the engine to go. Causing a disconnect of the battery in the trunk to the engine.

2014 Audi A8LElectrical system

When the sunroof retracts or closes it makes a loud noise (sounds like an mri machine). I keep it closed for possible glass cracking safety reasons. This occurs while idle or driving on any street/highway surface. Audi thinks its a motor issue and is not covered by warranty or any recall.

I was driving on a suburban city street in a straight line with no cars or any other obstructions ahead of me or behind me. Without warning, the car engaged its emergency braking throwing my daughter and me forward violently into our seat belts. When I fell back, the dashboard was showing me a proximity warning but again nothing was anywhere near our car. The servicing dealer said they didn't find any error codes and so there was nothing they could do. This hasn't happened again (yet) but the cameras all around the car that engage for parking and in reverse are constantly going out and/or the vehicle mmi system randomly retracts into the dash while driving.

from the battery compartment. A plastic panel was removed for inspection. Located directly under the battery was a plastic module identified as trw *334 gnoacdobnc28u* and stamped made in malaysia??. The dealer stated that the module controls the electric parking brake for the car. Inspecting the unit, multiple wire leads that feed the e-brake control unit had burned through, as did a portion of the e-brake control unit. The body area of the car near the unit was covered in soot from the electrical fire. Years prior, the driver had issues with the e-brake, the e-brakes failing to release prompting the vehicle to be towed to the dealer. At that time the service representative walked the driver into the service area to show the driver corrosion on the electric contact leads from the control unit. The representative suggested that perhaps battery acid/gases may have run down the battery into the control unit causing the corrosion. The unit may have been replaced at that time along with the battery. Photos are available of the control unit upon request. *Tr

Dt: the contact stated a gallon of milk spilled into the driver's seat. The milk spilled underneath the seat. When this happened it shorted out the electrical module that operated the dashboard lights and headlights. As a result the lights were blinking in and out. Currently, the vehicle is at a certified dealership for repairs.*Ak updated 12/27/2005 - the tire pressure monitoring light illuminated on the dash. The dealer replaced the module.
