Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The vehicle software (known as Audi MMI) has been continuously rebooting every 30 seconds after the vehicle is started. This causes the entire dashboard (and entertainment screen) to repeatedly reboot which is very distracting while driving. While backing out of a parking spot, the MMI system rebooted which then disconnected my backup camera, blind spot warning, and rear collision warning systems which resulted in me almost hitting a car crossing behind me. There are zero messages anywhere in the car that an issue is present.”
