The right rear liner is cracked and I noticed that it is partially supported by the rear bumper, where the bumper wraps around the corner. Their are those special plastic fasteners that hold the liner in place. Eventually, I will have to replace the liner and was wondering if any of you guys have had this problem ? If so, how do you remove the plastic fasteners ?

MAC, those are the push pin retainers. You have to work the "pin" portion of the retainer out to collapse the inner part of the retainer, then the whole retainer comes out. They are sort of like the dry wall anchors that expand in the wall when a screw is threaded into them.

Thanks Mark, I finally got the fasteners figured out. Now if I can only work up enough courage to call the dealer for a price.
