MMI - Multi Media Interface constantly reboots about every 90 seconds. This is a safety issue since if I am backing up and the MMI reboots I lose the backup camera and when the MMI reboots I also lose collision/parking/proximity sensors. This issue started happening with my Audi on 7/26/25 and can be reproduced every time the ignition is on or car is running. From doing a quick search on the in…

THE RADIO (MMI SYSTEM) IS REBOOTING WHILE DRIVING EVERY 5-10 MIN. DEALERSHIP CAN'T FIX AND IS AFFECTING SAFETY SYTEMS LIKE FRONT AND REAR CAMERAS/SENSORS.
Audi MMI reboots constantly while the car is one. There is about 30 seconds between each reboot. This causes certain safety features like the backup camera to stop working when in use. I am not sure what the cause is but this seems to be a more common issue with the 2020 Audi's.
MMI system is failing, parking assist is malfunctioning, back up camera doesn’t activate, CarPlay turns off mid drive and reboots, navigation not working, car wants to brake at highway speeds as computer system malfunctions, Bluetooth phone connection drops mid call, overall the computer infotainment system has failed.

When the reboots happen, the screen goes black and key systems such as the backup camera, rear obstacle detection, and navigation, become unavailable until the reboot completes and the systems reload. The reboots have affected other sensors/systems in the car like resetting my stored tire pressure values resulting in a TPMS malfunction w…

The MMI spontaneously reboots numerous times while driving. When the reboots happen, the screen goes black and key systems such as the backup camera, rear obstacle detection, and navigation, become unavailable until the reboot completes and the systems reload.

I own a 2020 Audi S5. The central infotainment screen (MMI) has been randomly restarting while driving. At first, it only happened occasionally, but the issue has gotten significantly worse. It now restarts every 5 to 10 minutes during normal driving. When the screen reboots, I temporarily lose access to important vehicle functions, including the backup camera, navigation, and audio controls. This…
The mmi system reboots randomly throughout nearly every drive. This has happened when backing up causing a loss of access to backup cameras and sensors making me stop in the middle of the road.
The MMI restarts constantly every day sometimes multiple times within minutes of each other. There is no correlation with other vehicle feature or functions that cause these restarts to happen and they are not in any specific pattern . When the MMI system reboots, the rearview camera and parking sensor display go dark, making parking and reversing unsafe, which directly impacts the functionality…
