Right side mirror..the covering which camera attached fell off as we traveling 65 m/ hr

As we travell going to Sallisbery University going to the bridge ,The car is running 65 m/hr.The right side mirror under the side mirror fell down suddenly .something slams on the door .(No scratches no issue or sign that it was damaged).It just fell we heard a bang and then we slowly I stopped the truck to look at it and see that under the side mirror missing the cover and camera is not working anymore.

 

First, Welcome from LA (Lower Alabama)! I would talk to the dealer about claiming a warranty issue. I don't see any evidence in this photo of anything hitting the mirror, knocking the camera and housing off.

 

Search around on here a bit. You aren't the first that this has happened too.
