Hi Ruby,
Thanks for that. Mine is very infrequent and for the life of me hasn't made the noise in the last few days. As you mentioned if it's out of place slightly the noise is there but after the plastic is pushed on a bit at the bottom of the pillar near the windshield, it tends to suppress it or make it go away. I think the build quality on these is better than my last ride. The solid feel over bumps is impressive. At least I know that if it starts to come up again, I know just where to go. Not bad enough at this point to do much about it. On my 2010, I removed the pillar trim and put 3m insulated electrical tape (black and rubbery) around the tabs at the base of the trim. It made the fit snug back into their slots and the thing didn't make another noise ever again. If the construction is the same on these, I will do the same if it gets worse.
