Four problems related to rearview system braking have been reported for the 2020 Audi S4. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2020 Audi S4 based on all problems reported for the 2020 S4.
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 multimedia interface (mmi) touchscreen radio will constantly reboot while driving regardless of variables. Diagnosis’ have proven problem to be undeterminable, this is a serious safety concern as I have lost back up camera and other safety features while driving, while I await the system to reboot. This reboot has been occurring non-stop since January. My research online and in other forums has led to a substantial group of vehicle owners suffering from the same issues across their vehicles. Audi has made no effort to rectify with the dealership simply stating they can charge to diagnose or replace. If it was an isolated incident I would be understanding as maintenance problems will arise, but to have a substantial population discussing this issue ad nauseum seems to be more widespread with no solutions.
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.
