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 (11/13/23 production). 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 (production date 9/18/23). 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. 3rd replacement 9/9/25 (production date 9/18/23) and has had the same issue on 4/18/2026 at 66,528 miles and once again on 9/30/2026 75,069. The 3rd replacement failed before the 12 month, 12,000 miles warranty but then was out of warranty by the time anything could be done.

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 federal safety agency 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 the federal safety agency to investigate this matter and determine whether a recall or safety bulletin is appropriate. Thank you for your attention. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
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 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 automatically fail and reboot while turned off. This will turn the screen back on in the start-up mode and cause the radio to turn on randomly. When this happens, the stereo volume will sometimes come back on, and other times it appears to be playing music and radio stations, but the volume control will not work. Then it will randomly come back on very loud. The distractions are unavoidable, as I would be happy to just leave the MMI system off, but it is not possible! Please require Audi to fix this problem!!! The dealer/manufacturer does not seem to be interested in fixing the issue, as is evidenced by the many complaints I have found on the federal safety agency website.
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.
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 main screen of the vehicle, which is called the MMI from what I understand, repeatedly shuts down and restarts while driving, up to 5 times or more per hour while driving. Sometimes this process can take 3 or more minutes. There appear to be hundreds of Audi customers that this affects according to my research. The dealership (Audi of Nashua) charged for a possible software update repair that did not work, and do not seem to be familiar with a fix other than a $5,000+ repair to replace expensive hardware components. This is a major safety issue because it is what controls the phone and GPS system, causing serious issues when trying to navigate in unfamiliar areas or when taking important phone calls from family members. It is a major distraction while driving and greatly increases the risk of accident.
The Audi MMI (Multi Media Interface) system plays a crucial role in enhancing safety features by providing a user-friendly interface for managing various driver assistance systems and safety-related functions. These include features like emergency calls, roadside assistance, and the integration of driver assistance systems like adaptive cruise control and collision avoidance assist.
