1 Blind Spot Detection problem of the 2021 Audi A4

Failure Date: 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.

3 Blind Spot Detection problem of the 2020 Audi A4

Failure Date: 06/09/2025

Mmi shuts down and reboots randomly without warning and multiply times a day. All the backup camera and safety warning features were disabled while mmi is off. Huge safety concerns!.

4 Blind Spot Detection problem of the 2020 Audi A4

Failure Date: 04/15/2025

While driving. These reboots typically happen every 5–10 minutes and result in the temporary loss of safety-critical features like the backup camera, navigation system, and rear cross-traffic alert. The screen goes black, and the system restarts itself while the vehicle is in motion, which is both distracting and potentially dangerous. I brought the issue to my local Audi dealer, who attempted two separate software updates. Unfortunately, the problem continues. The service department reports no faults in the system diagnostics and has stated that they currently do not know how to fix the issue. This persistent malfunction affects key safety systems and creates significant concern when driving.

5 Blind Spot Detection problem of the 2021 Audi A4

Failure Date: 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.

Mmi system in 2020 Audi A4 keeps blacking out and constantly rebooting while driving. This issue happens while going in reverse, which crashes the backup camera and triggers a safety warning in the car. It also happens while idling, which also triggers a safety warning in the car about the backup camera being inoperable.
