My ST is less than a year old with 12K+ miles on it. Anyone experiencing a persistent rattle in the tailgate. I sat in the back while someone else drove and the rattle is definitely originating behind the trim panel where the wiper motor resides. Being in warranty, it's going to the dealer where they can fix it. Anyone dealt with this or had it fixed? Another minor irritant is where the phone charger used to reside; anyone experiencing that rubber pad bubbling up in the middle? It's like it needs to be glued down flat?
