I'm in the same boat. 2011 X5 35i M Sport.
I have active threads on Xoutpost, Bimmerfest, and this forum.
My car is currently at the dealer. Rockers and fender flares getting repainted on Weds, and they are keeping the vehicle for 30 days until they can apply Avery Dennison Nano-Fusion. My dealer has been fairly cooperative, but I think a coordinated effort is best. The dealer is only three years old and they claim this is the first time they've seen this issue.
Here's one of my threads.

I'll help any way I can. BMW need to wake up on this issue. To have a one month old BMW customer as pi**ed off as I am will have lasting implications.
