The inside rear door panels on my EX are coming loose from the fiberglass. They use a plastic push pin type mount that seems to be a one time use kind of thing. I pulled one off and it seems to be ok. The female part that would be mounted on the inside of the door has pulled out of the door and is attached to the male barbed part. It mounts in a slot on the inside of the fiberglass door. I had the dealer order me a few new ones so we can see if there is a difference. Any ideas?
