While driving yesterday, the mmi reset and included the dashboard. The dash completely froze for a couple minutes(including the speedometer), and then the whole system blacked out and restarted. There has been a check engine light on since I got the car in December. Havent been able to get a service appointment with a loaner. Also since new, adaptive cruise control works intermittently with a warning that a door is open(when all doors are completely closed).

Safety is at risk because a vehicle that cannot reliably engage park may roll away and injure occupants, pedestrians, bystanders, or service personnel.
