1 Adaptive Cruise Control problem

Failure Date: 02/17/2025

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 mid-February 2025 and the vehicle has been inspected by a mechanic who verified the concern and attempted a factory reset (which did not solve the issue), and they continue to claim there's nothing they can do since their obd scans return no fault codes, even though there are numerous tsbs (filed with NHTSA) that point to available software updates that should be applied to address infotainment-related issues. 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 input to restore, while driving. I have also filed a case with Audi customer experience (as many other customers have for this issue) and the number is [xxx], opened on 5/2/25, and I'm still pending for a satisfactory resolution. Relevant TSB numbers include: TSB 2067021, TSB 2076404, TSB 2069112 information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
