Ceric is exactly correct.
There is a TSB that states these pieces were painted defectively. I had all of my CX9 2009 silver trim pieces replaced w/in 4-5 weeks of the purchase.
You should have no problems in getting all of them replaced, including the ones that are not scratched...tell them you want them all replaced so neither you or the dealer has to address this same problem in the next 1-6 months.
