I recently purchased a 2011 Chevy Traverse. Before it had 3,000 miles, the molding "pitted". When you look in front of the rear wheel, it has a dirty look to it. I've seen it on practically every Traverse that I've come across, yet the dealership is only going to replace the molding one time. This problem will continue. Please check your Traverse and go to the dealer and inform them of this problem. This is a manufacturing defect and we need to get General Motors to recall these and fix the problem.
