I have a '17 1500 Longhorn. My mirrors make a slight audible clunk when retracting BUT they DO NOT hit the window. I believe this is normal. The issue I have is if the mirrors are retracted and you go to extend them (or visa versa) one or both of them try but don’t make it. I have isolated my problem to water freezing in whatever position it was left in. The challenge I had was having the dealer duplicate the problem. Finally, on a 23F morning after a previous rain, I was able to duplicate the discrepancy at the dealership. I did get FCA involved. All fixed BUT I believe the problem will happen again due to the design. Put it this way.....for me...if I lived in FL...i d believe I would have the problem.
