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 dist…
I am submitting a formal complaint regarding a persistent and dangerous issue with the MMI (Multi Media Interface) system in my 2020 Audi S4.

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 whi…

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 …
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 fact…
