Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“The MMI reboots continuously throughout my drive - whether it is 1 minute or an hour. It does this without a Bluetooth connection or wired connection. There is no ability to use hands free calling, listen to the radio, use Apple car play, Bluetooth, navigation, back up camera, parking assistance… It is startling to have your camera black out on your as your backing up (may back up camera works for about 45 seconds before stopping) I have done a hard reset. …”

NHTSA complaint #11675209, filed 2025-07

“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 factory reset (which did not solve the issue), and I have performed an OBD scan, which returned no fault codes. …”

NHTSA complaint #11662464, filed 2025-05

“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. …”

NHTSA complaint #11674842, filed 2025-07

“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.”

NHTSA complaint #11663689, filed 2025-05

“The MMI (multimedia interface) screen goes dead and reboots frequently (every 2-5 minutes) while driving. It is extremely frustrating and distracting. 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 while driving and requires me to re-enter navigation destination while driving. …”
