I have a 2019 Audi Q8 with 39k miles. I just received an indication stating that an electrical issue has occurred and to contact service maintenance. While on my way home from work with the electrical issue active the air conditioning stopped working which appeared to be unusual. I was able to still drive the vehicle home. I then searched on Google about the issue and read numerous complaints through various forums regarding the issue. Most of these issue were similar to my experience. Also these complaints were around the same year and mileage of my vehicle. Please help to have Audi resolve this issue.

Driving vehicle at a low/medium rate of speed, and car completely shut off without warning. Check engine light appeared after restarting the vehicle. This is the second time this has happened to me since November 2022. I filed a report then as well. This car should not be allowed on the road and Audi should be forced to buy it back. The vehicle has less than 35,000 miles. Dealer has not confirmed what the issue is this time.

I am the owner of a 2019 Audi Q8, purchased on 8-8-19. I have had repeated issues with the driver's side seatbelt twisting and retracting the twisted portion up into the B pillar. I have had this issue repaired 3 separate times at my local dealership, most recently in June of 2023. Just 2 weeks after having it repaired, it twisted for the fourth time in early July. It has therefore been witnessed and documented by the dealership each time it has been repaired. The issue has never happened to me and has always happened after my husband has driven my car. So I cannot tell you what exactly is happening to cause this. There is a TSB regarding this problem. It is NHTSA ID Number: 10233615 published on 3-29-23 (the original TSB was NHTSA # 10158643 published on 4-1-19). The Manufacturer Communication Number: A6923872058455_6 I am concerned that there could be a safety issue while the seatbelt is in this twisted state. Thankfully I have not been in any accidents/incidents where the seatbelt malfunctioned. But how can I confidently be assured that the seatbelt will continue to function properly? It is not normal for a seatbelt to due this. I contacted my dealership on July 21 to have it repaired again under warranty, but they told me that I would have to pay to have it fixed again. They claim that it was never covered under warranty and that they repaired it each time for free. This was the first I had heard that is wasn't covered under my warranty. I escalated this issue to Audi of America, reference #05805277. I heard back today that the dealer claims "outside influence" as the cause of this seatbelt problem. Therefore, they will not repair it as it does not constitute a manufacturer's defect. I do not feel safe driving with my seatbelt in this condition. I am hoping that the NHTSA can guide me in the right direction for a resolution to this matter.
Electrical system malfunction caused the car to come to a stop in the middle of a busy highway.

Electrical system malfunction caused the car to come to a stop in the middle of a busy highway. The vehicle needed to be pushed off to the side of the road by other parties as steering became increasingly difficult to navigate to the side of the road. The vehicle was stuck in neutral and could not start the engine to drive again. The vehicle needed to be towed to the closest dealership for further investigation.
Car started flashing all kinds of warnings, then cut off and had to coast to the side of the highway. Then could not get out of the car and the entire system was in complete failure so the doors would not open. Absolutely terrifying experience. Audi knows this is a bad issue and it keeps happening to thousands of Audi owners …
