Example complaints

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

“while driving. These reboots typically happen every 5–10 minutes and result in the temporary loss of safety-critical features like the backup camera, navigation system, and rear cross-traffic alert. The screen goes black, and the system restarts itself while the vehicle is in motion, which is both distracting and potentially dangerous. I brought the issue to my local Audi dealer, who attempted two separate software updates. Unfortunately, the problem continues. …”

NHTSA complaint #11665454, filed 2025-06

“MMI system in 2020 Audi A4 keeps blacking out and constantly rebooting while driving. This issue happens while going in reverse, which crashes the backup camera and triggers a safety warning in the car. It also happens while idling, which also triggers a safety warning in the car about the backup camera being inoperable.”
