I saw this post of another forum. A Challenger, with 100K miles experienced a rusted rear engine cradle bolt, due to exposure to salt water. Supposedly, the problem was caused by a deteriorated rubber cover over the hole in the frame that is used to block water and debris from getting into it. The damaged cover apparently acted as a funnel for water to enter the frame rail dumping it onto the bolt. I know the Pacifica also had this problem. Has anyone heard of this issue on Challengers?
