Regularly my mmi will restart, screen goes blank, comes back and says I'm not the registered user. Then bluetooth won't work and I get park aid errors and no rear cross traffic or anything. Happens at least 2 times each way to and from work ( 45min ). I usually have to hard reset it twice to get things normal and an ignition cycle to get park aid back.

The mmi restarts constantly every day sometimes multiple times within minutes of each other. There is no correlation with other vehicle feature or functions that cause these restarts to happen and they are not in any specific pattern . When the mmi system reboots, the rearview camera and parking sensor display go dark, making parking and reversing unsafe, which directly impacts the functionality of the parking collision warning and rear cross traffic warning systems.
