There are supposed to be "stronger" clips available for holding it on. You could ask about that (at the dealer).
neone has a part number for the new clips? this friggin bumper gap annoys me every time I walk to my car....//
Ours goes from zip at the wheel well to a bit more than 1/8" at the rear corner. Just an irritant, but it's hanging in there, I think.
I used rubber to go under bumper wrap clip closest to hatch and then put a piece on upper end of both screw/spacer holes on rear of bumper wrap as i held it up and then snugged the screw in as to not strip plastic. Seems to have improved some.
I fixed my bumper gap on both sides of my 2012 with a part I found at Home Depot Everbilt Clear Bumpers 1/2” x 1” Both sides of my bumper where hanging off because the clips weren’t “locking” in. Removed the 1 screw from in the wheel well (right in plain sight) then pull back the bumper so I could see where it’s supposed to connect. To fix I cut each clear bumper in half (long ways) otherwise the bumpers push the actual bumper out. I put them where the clips need the extra “push” up. Used a flathead screw driver to secure the sticky side down and then popped the bumper back on. There bumpers are soft enough to budge a little which is why how thick they are works perfectly.
