NHTSA Complaint #11674670 — 2020 AUDI A4

The infotainment system (MMI) in my 2020 Audi A4, currently running software version 3243, frequently reboots on its own while driving. When this happens during reverse, the rearview camera shuts off and the screen goes black, eliminating all rear visibility and creating a significant safety hazard. Additionally, the reboot causes Apple CarPlay to disconnect mid-drive, resulting in loss of navigation, traffic alerts, and voice directions, which increases driver distraction and risk. The issue occurs without warning lights or error messages—the screen simply goes black and restarts in a few seconds to a few minutes. The problem began a few months ago and has become more frequent over time. While I have not yet had the issue inspected by a dealer, it is widely documented by other 2020 A4/A5.. owners and has been resolved in many cases by updating the MMI software to version 3696. Audi has issued related Technical Service Bulletin (TSB 2078437/1), but no recall or service campaign has been announced. I believe this is a manufacturer defect that poses a safety risk and should be investigated. The affected components remain in the vehicle and are available for inspection upon request.
