2020 Audi S4

The MMI reboots continuously throughout my drive - whether it is 1 minute or an hour. It does this without a Bluetooth connection or wired connection. There is no ability to use hands free calling, listen to the radio, use Apple car play, Bluetooth, navigation, back up camera, parking assistance… It is startling to have your camera black out on your as your backing up (may back up camera works for about 45 seconds before stopping) I have done a hard reset. This is a problem that I am reading over and over and over again on forums I live nearly 2 hours from a dealer who takes weeks to get into and looking at a huge bill Hoping there is a fix soon

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 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 NHTSA website.

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.

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, as the reboots can happen in the middle of a reverse parking maneuver, and they render the backup camera and obstacle detection sensors completely inoperative until the system reloads. They also impact safety on the highway, as the reboots completely disable the navigation screens and require multiple user inputs to restore, while driving.
