2020 AUDI S4 Back Over Prevention Warnings Problems

I am submitting a formal complaint regarding a persistent and dangerous issue with the MMI (Multi Media Interface) system in my 2020 Audi S4. Since February 2025, the system has been spontaneously rebooting both while the vehicle is idling and in motion. When this occurs, the screen goes black and critical safety systems such as the rearview camera, parking sensors, and navigation become unavailable. The system requires driver interaction to restore functionality once it restarts, creating a major distraction. These reboots now occur every few minutes, severely affecting both usability and safe operation of the vehicle. Initially, this issue happened infrequently (about once every two weeks), but over time it has become constant. Based on extensive online reports from other owners—including threads such as this one on AudiWorld: [XXX] appears to be a widespread defect affecting other Audi A4/S4 vehicles of the same year. This malfunction compromises several driver assistance...

The main infotainment system is stuck restarting every 1-2 minutes. When the car is put into reverse, the rear back up camera will turn off while the vehicle is in motion and not resume.

The vehicle software (known as Audi MMI) has been continuously rebooting every 30 seconds after the vehicle is started. This causes the entire dashboard (and entertainment screen) to repeatedly reboot which is very distracting while driving. While backing out of a parking spot, the MMI system rebooted which then disconnected my backup camera, blind spot warning, and rear collision warning systems which resulted in me almost hitting a car crossing behind me. There are zero messages anywhere in the car that an issue is present.

The MMI (multimedia interface) screen goes dead and reboots frequently (every 2-5 minutes) while driving. It is extremely frustrating and distracting. In addition, when the screen blacks out while driving in reverse, the backup camera, back up sensors and cross traffic warning systems do not operate until the system reboots, which can take several minutes. This problem occurs constantly while driving and requires me to re-enter navigation destination while driving. Using CarPlay for navigation is also affected, as the system reboots whether or not I am using a secondary media source like CarPlay, and I have to re-enter the destination whenever the MMI reboots. Also the MMI needs me to re-enter user information on the screen with every failure in order to get the system running again, which is very distracting while driving. I am not even able to turn off the screen to avoid the distraction, as it will...

My Audi has been having an ongoing issue with the MMI rebooting while i am driving. It takes away my ability to see the maps and or hear the map telling me which direction to go. It has not been inspected yet however it is a common issue with the 2020 Audi cars that can be replicated however it is not predictable.

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. Restoring functionality requires user input to get through the loading screens. The issue started in February 2025. I have attempted a factory reset (which did not solve the issue), and I have performed an OBD scan, which returned no fault codes. This appears to be a widespread issue based on the numerous reports found on user forums online, affecting the same model year vehicles (for multiple examples, refer to [XXX] ). It is also interesting that most of the users experiencing this issue also report it starting around the same time (Jan/Feb 2025), and they all have similar software versions, and likely production dates. This should be considered a safety issue,...

Audi MMI (infotainment) frequently resets during use of car. Spoke to tech at audi and they confirmed this is an issue on many 2020 audi A4 and S4 vehicles. The blind spot monitors, parking sensors, and backup cameras all disabled when this happens. It can happen at any time.

The primary infotainment/mmi screen randomly turns off and a system reboot occurs, which can take a period of time. This causes a loss of all parking sensors, rear view cameras, navigation etc. Dangerous when the system dies in the middle of a bustle parking lot or having to restart the system at high way speeds. Issues started suddenly around February. No fault codes in the car but problem persists.
