Tires
08/10/2025
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)

Power Train

I am writing to report a persistent issue with my 2021 Audi A4, VIN [XXX] . I have been experiencing a noticeable vibration, humming, and shuddering sensation that occurs specifically when turning at slow speeds (e.g., in a parking lot or when making a tight turn at an intersection). This issue has been diagnosed at a dealership, and the diagnostic report from the service invoice dated 07/12/2025 noted "VIBRATION HUMMING SHUDDER WHILE TURNING." The vehicle's mileage at the time was 38,888 miles. Dealership diagnosed this issue as a failing AWD clutch system. I took the car to a different repair shop, and they redirected me to the Audi Technical Service Bulletin (TSB). The symptoms described in the TSB—"vibrations, humming, droning, or rubbing can be heard and/or felt in the vehicle interior... when the steering wheel is turned to full lock"—perfectly matches my experience. TSB Link - [XXX] The vehicle details are: Model: Audi A4 Year: 2021 VIN: [XXX] Current Mileage: 39490 Sinc...

Unknown Or Other, lane Departure, forward Collision Avoidance
08/13/2025
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.

Electrical System, lane Departure, forward Collision Avoidance
03/27/2025
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.
