2006 GMC Sierra 1500 crew cab. Only a year old and with less than 15,000 miles, the right tail light assembly fell off. There had been no accident, impact or abuse. The cause was the breaking of the two plastic threads in the taillight assembly. These flimsy, weak, threaded parts are all that hold the taillight on and are clearly inadequate for the load. This should not be a wear and tear item; it is a design defect. There should be some metal holding the screws, not thin plastic.
