A few years back we heard on here that some 2009-2012 (maybe 2013 also?) Challengers had experienced small, unexplained "Mystery Dents", mostly on the roof. Possible causes being torsion stress points or the sheetmetal braces not being properly glued, or whatever. Just curious - has anyone with a 2014 or 2015 experience these mystery dents? I'm wondering if Dodge has remedied the problem in the newer manufacturing process.
