My right rear mudguard US version is fell, that the tape was not securely attached to my bumper. Any idea to fix this problem.
Ask yourself for a warranty replacement. LOL. Get some better double sided foam tape. Did those things drop your highway MPG?
I installed mine and the tape seemed a little weak, so I added extra sheet metal screws on inner part of mudguards. I guess you could get better double sticky sided tape, but it's bound to come loose over time. No noticeable drop in MPG. I guess you could compensate for wind drag with a shark fin antenna.
Attached are photos of Front and Back Mudguard. You can see added screw on inner part of MGs. I figured it would help, especially when slush builds up in winter.
I don't know exact size, simular size as stock screws. I didn't use clips, just drilled a little hole and screwed into plastic fender piece.
