I'd start with the "general wonkiness" fix:

Unplug the negative terminal for the battery, leave it off a few minutes to reboot all the ECMs and computers
Reconnect the battery and place it on a trickle charger (properly - negative terminal on chassis ground or the side tab of the battery terminal -- not on the battery post itself) overnight.
See if that helps anything

Also - check the wiring under the main fuse panel in the engine compartment. A lot of folks have reported loose mounting bolts, loose harnesses or loose wiring here and it's caused random gremlins from the factory as well. Look for blown fuses while you have it opened up.

Funny thing also after all this happened and came back on the windows would not come up automatically.
For anyone that understands the computer system, the deal is saying 20 out of 29 modules are not communicating. They say it could be a chain reaction whee one or two affect the others.

any help.

I’m having the exact same issue with my ‘23 Black Diamond. It’s intermittent and extremely frustrating.
Did you find a solution?

2 1/2 weeks at the dealership and all they did was disconnect and reconnect alll the modules and trace each wire for loose connections. Found nothing but issue has stopped for almost a month now.
