I have a 2011 RT-S with 4,000 miles on it. I had it in for its 3,000 mile service in June 2012 had the new side panel and filter housings installed. Everything was good then a couple of weeks ago I was backing it in to the garage and heard this unusual noise. It sounds just like a brake pad is loose. Has anyone out there had the same problem? Thought I would check here before I put it on the trailer and took it to the dealer.
