I have removed my ‘15 grille many times. It is all clips and four small Phillips head screws. The worst part is they are on the very bottom edge (inside) difficult to see - two require a very short shafted screw driver to access, and not too easy for big hands. Do not attempt to remove the grille in cold weather (as I did) as the clips are fairly fragile...How difficult is it to remove the grille of a 2016 Forester.?
