The rear long narrow reflectors on the top edge of the tail gate have been known to bow over time. Mine did and were causing rattles as they rubbed against the top tail hatch. I tried double stick foam tape, it didn't work. I removed the reflectors, placed them in the oven at about 200 degrees F for about 20 minutes. I then removed them, bent them perfectly straight, and "set" them with cold water, this worked great and saved me $30 for new ones.
