Rattle in tailgate

[MGreen6]

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?

Mine seemed to have a noise under the trim on the hatch after I did the wiper delete, I assumed it was due to that.
Ended up Cutting a piece of foam to fit the space left after taking out the wiper motor, attached with some 3M tape and it’s been quiet since
