UPDATE!
Had the battery load tested and it came back with only 460 CCA. So the 12V battery was dying and the jeep was using the 48v to start the engine.

Purchased a new H7 Yellow top from Advanced Auto Parts and that has seemed to cure the issue. Now however the 8.4 UConnect is missing some functionality (advanced climate control, XM, and Offroad pages). Other threads say that will come back after a couple of starts.

Thanks for the input from everyone
Awesome man! Thanks for the closure. After I installed Aux switches I had the dealer flash done to enable them. Not sure if it was the 2 hours or 3 restarts but they finally showed up in uConnect. I’ll keep my fingers crossed for you.

Yup, after a couple/few on and off cycles / in time ORP, etc. will return. You can speed up the process if you want... With the engine running pull fuse F97 for 10 seconds and then plug the fuse back in... This causes UCONNECT to reboot and 99% of the time it will get ORP, etc. back, right then.

this is good to know. I had a real shit experience with the aux setup in my 2018 and got a 2021 with eTorque hoping it would be better. I can accept the 12v batteries are crap, as those are easy enough to deal with. I would have been really upset hearing about the 48v being the culprit.

good to know, I was so used to it working I had a real WTF moment when it reverted to so worse version of itself
