Knowledge is power, right! Pun intended for the electronics minded.
Anyway, I ran a search and didn't see anything pertaining to this but I had the trunk fuse box open last week for a general "the hell of it" inspection and noticed several of the fuses and more so the relays were quite loose. I pushed most of them back into their respective slots.
I can only assume the Charger has a bit more jiggle in the rear, allowing the components to work loose over time. Perhaps this could lead to electrical malfunctions if they get too loose.
Just something to keep in mind when chasing those pesky electrical gremlins.
I have yet to check the fuse box under the hood.
