NHTSA Complaint #11674842 — 2020 AUDI S4

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.
