[6XJeep]

Our 2015 Renegade had just come home on a trailer after 2 months at the dealer for an electrical gremlin. It seems that there is a failure in one of the many wiring harnesses that attach to the Body Control Module, which was just replaced. The dealer is not sure which one so they recommended we replace all the harnesses for $5400. Way too much. Some Renegade forums indicate that other people have had a similar issue. Wires get kinked and fail. But the question is, which harness has the failures and approximately where is the failure? I suspect these failures may all be from a similar cause. Has anyone had a similar issue? If so, where did you find the problem? A connector? A wire? Which one?
