The passenger side back tail light rubbed the paint down to the white primer. It was at the bottom of the tail light on the bed side. I went to the dealership and showed the service people, and asked if they were having any problems like this, and they told me no. I went home and took the tail light out and found there was a sharp edge when the light was formed. I fouled the edge down and touched up the paint myself. So far so good - for now.
