2020 Audi A4

The dominant pattern in 2020 Audi A4 complaints centers on the electrical system and the backup camera. The MMI infotainment module is the most frequently described problem: owners report it randomly going dark and rebooting while driving, which simultaneously kills the navigation display, audio, and, most commonly flagged as the safety concern, the backup camera feed. The backup camera losing its image mid-reverse is the core of the back-over prevention complaints, and most of those trace back to the same MMI reset behavior rather than a separate camera failure. Lane departure warnings generating false alerts or behaving erratically represent a smaller but recurring thread. A single report describes a driver's seat bracket snapping and separating from the seat track, and isolated complaints mention accelerated front tire wear, but neither appears with enough frequency to indicate a broad pattern.
