RE: clunck on backing out of parking spot
I have the same problem with the Challenger and also had the problem with my 300C SRT8. Seems there is a problem with brake clearance and on a tight turn in reverse, things get hung up. Pull your front wheels off and you can see where it hits. Chrysler replaced the calipers on the 300 under warranty (after the service department tried a 'lets just grind some off here at the shop" fix [:@] ) .
