Power harness is an ongoing issue. Mine was different, but I would suggest you have your dealer check the Jcase fuse block. Pull the fuses and confirm inside is not starting to overheat at the connectors. Also have them check the back plug of the Jcase to the harness.
Dealer will need to make a strong arguement.
If you have any mods they will push back
I called dealer told this to service foreman, he says no, no, it’s a separate circuit.
