2021 Audi A4 owner complaints

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

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.

The main instrument cluster is not stable- it tries to start up then crashes. As a result, speedometer, rpm’s, gas tank gauge, etc are not available while driving. The screen displays blank with a red triangle, tries to start up then crashes again. This seems similar to Audi recall campaign 90VC, but for some reason the A4 was not included in the recall, but I’m having similar symptoms with my A4.

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 inte

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.

The reversing image occasionally appears white screen phenomenon During the process of reversing, the reversing screen suddenly turns white and cannot see anything behind, which brings danger to the driver and others, causing danger to life and property. Apparently the dealer didn't take this seriously

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 contact owned a 2021 Audi A4. The contact stated that while driving at a low rate of speed through a parking lot, the vehicle independently accelerated and the brake pedal locked. The vehicle accelerated up a hill as the contact was unable to depress the brake pedal; he collided with an electric pole which caused the vehicle to stop. Due to the shock and abruptness of the failure, the contact was uncertain if any warning lights illuminated the instrument panel. The air bags did not deploy upon impact. The contact and no other bystanders were injured as a result of the failure. The police and fire department arrived at the scene and a police report was filed. Due to the failure, the vehicle was towed from the scene to an independent body shop. The dealer nor the manufacturer had yet to
