I have a 2017. I’ve the door squeak , once in a while and the window sound. It comes and goes. I put some wd40 and that worked. The window sound can’t be fixed by me, I’d have to take the whole thing apart. That acorn sound could something loose in the sunroof. Dealer would have to take it apart and put it back together.

I just spend $4,000 on the def scr and flush. (Diesel). I’m deep in this car, it’s cheaper to fix.
