2020 Audi S4 Problems

My instrument cluster and its replacements have malfunctioned multiple times. The original instrument cluster/virtual cockpit failed to boot and had a black/blank screen on 4/19/2024 at 29,687 miles and was replaced on 5/15/2024 at 29,923 mi. That replacement one worked fine for a while and then did the same thing on 7/15/2024 at 33,655 miles and on 1/10/2025 at 42,532 miles. The instrument cluster was then replaced again on 2/10/2025 at 43,841 miles. That replacement unit took only a couple of days to act up again with the blank screen on startup on 2/13/2025 at 43,965 miles and once more on 8/1/2025 at 52,673 miles. I'm currently waiting to hear back from the dealer to get the instrument cluster replaced once again.

The Audi MMI malfunctions and reboots randomly while driving. Possibly being a software issue. There is a TSB code that the dealer used to reference for me ( TSB 2078437/1), but I cannot find it on the NHTSA website. The reboot issue shuts off all functions associated with it, including, but not limited to: navigation, rearview camera, and parking sensor use. This poses a risk since it can be distracting to pull back your navigation while driving or having your rearview camera cutoff mid mid-use. The issue does not appear as a warning lamp or any type of notification, and there are multiple reports of similar issues on online forums that have not been addressed.

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 and safety features, and I believe it presents a serious hazard, especially if it occurs during parking, reversing, or navigating unfamiliar areas. I urge NHTSA to investigate this matter and determine whether a recall or safety bulletin is appropriate. Thank you for your attention.

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.

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.
