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).

This report is on a new vehicle. The incident occurred within one week of purchase. While driving on a freeway at constant speed, with the closest vehicle in front of me approximately 25 yards away and with no warning, the car slammed on the brakes in an emergency fashion and aggressively tightened the seat belt shoulder harness. This was followed by a notice "emergency call cancelled". It is clear that the Audi pre sense malfunctioned and caused the system to think a rear end collision was imminent, when clearly it was not. The internet is littered with complaints about this. Fortunately, this did not result in an accident, but I would classify it as a near miss safety incident since if someone had been close behind me it likely would have resulted in a rear end collision. I have reported this to the Audi dealer that I purchased it from. Given that I haven't had a car accident in forty years, I consider this system more of a safety hazard than a help.
