The instrument cluster has stop working. Have to monitore vehicle information, Mileage, service, Safty notifications and general vehicle information from the Audi app.

August 31, 2025Tires

Tires are original equipment. Only 19,000 miles on them. Was told all 4 tires have belt shifts and hop some. Suggested they should be replaced. These tires were great when new but you could tell from driving they were degrading. I'm [XXX] and never had an issue with tires this new. The belt shifting could be a manufacturing issue or hitting to many potholes. I suspect it is a combination of the two. Tire size is 245/40R18. Looking at internet reviews, these tires are great but wear out very prematurely. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The instrument cluster has failed per the recall 90VC. Audi issued the recall for every model made in 2021 with the exception of the A3 and A4 and I believe this was a mistake as my instrument cluster has the same failure.

I have a 2021 audi a4 that is also being affected by the instrument cluster failure/recall. My model , a4 was not included but I am experiencing the same failure and this was reported to the dealership. An online search will show just how many people have issues with the instrument cluster. The instrument cluster screen just went out while driving. I have to monitor my functions via the app on my phone. The dealer wants to charge me full price when every other model in 2021 has been recalled for the same issue. The A4 should be added to the instrument cluster recall for 2021 audi.
