I've got the plastic coming away on the Drivers side door, below the back passenger seat and in the right corner of the trunk. Anybody else having this issue?

I also have the fueling the gas tank issue but I see the thread on that here.

 

I too have had loose trim... I just reseated it myself, or added/put 3M Doublstick tape under the loose part.

 

A few weeks after I bought my 05 stang, I notice my trim above the passanger side door coming off.
I made an appointment to have it looked at. I took my car there and about 10 minutes later he came in and told me that the clip wasn't in place.
I know it sounds stupid to take it in for something like that,but why should I mess around with it and break it, whens its a brand new stang.

 

I've knocked the trim above the door loose with my big head. Just snaps back into place... sometimes a bitch to get right, though... but, as I've said here several times, the Mustangs are built like they were made out of legos.
