my back lip is falling off too, the crappy 1/16" inch strip of double sided tape cant hold it on. Nect trip to the dealer im going to yell. If they try to put that same size double sided tape on, I will kick em in the lip and go get my own tape. Cheap asses try to save on everything.
Edit: I have 2600 miles, mine started to fall off at about 1500.
