Hate to tell you this but For me this was 100% wrong, replaced the canbus box behind the glovebox and all my problems stopped. The old one looked to have residue in it left over from a bad solder job. been a few weeks and zero issues.
I love being wrong when it goes to someone’s favor. Glad it was just goo on the shoe and not foil in the oil! Thanks for the follow up, I’ll note your symptoms, findings and corrective action!

PS - Less Pepsi near the glove box…..LOL

It's not about that it in my case was the canbus module behind the glovebox. It's almost like it randomly shorts out and sends bad signals to everything. My symptoms were almost exact I have a video of my jeep trying to engage the gear without anyone even in it. It would do all kinds of insane things and throw you every message under the sun then go away. Jeep acted clueless about this and wanted a few k to diagnose. 6 bucks later smooth sailing.

With JLs, it is somewhat of a rule of thumb that the first thing to do when Jeeps start acting crazy, is open the fuse box and make sure all fuses and relays are pushed all the way into postion.

So much so that it should be one of the first things a new owner does upon purchase.
