While driving the rear half of the sunroof exploded. With no warning there was a sudden, very load "pop". The sunroof pane had completely shattered and was only held in place by the aftermarket tint layer that had been applied. The mesh shade that sits below the sunroof kept any pieces from falling on us while driving. Had the tint and mesh shade not been there, the interior would have been covered in glass. While we can't say with 100% certainty, we don't believe that any objects/debris hit the glass. The broken pane was on the back, downslope of the roof; if debris had hit it it would not have been a direct impact, but at most a glancing blow. We took the car to the dealer for repair. They immediately stated that it was due to rock/debris impact. The shattering does appear to originate from a single point in the glass, but there is not clear impact damage at that point. The origination point is smaller than a pencil eraser and is a square missing piece, of which there were many throughout the glass. I don't see the rough, crushing type damage I would relate to an object impact.

Audi's mmi has a parking aid which includes a 360 degree top view mode. Top view mode reverts to "graphic view" with each restart of the vehicle. Top view mode should keep the user's last setting which in my case is "camera view." Camera view is safer because the driver can actually see if there are any obstacles right up against the car (e.g. children) which sensors could miss. To switch to camera view, the driver needs to take their eyes off the road and click through the mmi menus. If parking with traffic, this is a distraction and also not safe. This defect in the software isn't being addressed by Audi in a timely fashion - it's been present for over a calendar year. New Audi vehicles apparently include a later mmi version which does not have this bug but they have not distributed a fix to existing vehicles.
