Is anyone else having problems with the rear bumper's blackprotector strip lifting in the center? After the car has been out in the hot sun for a while, the strip begins to lift in the center, and it looks like it could fall off even though it's firmly attached at the edges. The dealer said he'll order a replacement, but it seems that just a little contractors adhesive would solve the problem. Has anyone else had the same problem and how did you correct it? I have seen similar lifting on other T&C's and Caravans on the road.
