I had tons of issues with electrical my first 1000mi.
Cruise control, 8.4 screen bugs, rear cam, park sensors.
Hated this new jeep.
It may be a coincidence, but after solidly seating the fuses and relays in the fuse block by the battery, i havent had a single issue since.
Free and easy thing...

About a month after i bought it, 600mi or so, every time i put it in reverse, the rear parksense would act like i was always close to something. Chime like crazy intermittently.
Restarted vehicle and no change.
Restarted the ParkSense feature and it seemed to work...

Forward collision and ACC cruise lights came on.
Tried regular cruise. Regular cruise said no and light came on as well.
A trio.
Restarted. No avail, but regular cruise alarm went back off.
Tried regular cruise again about 30min later...all alarms shut off and everything...

Going downhill in 4L 1000rpm and holding. Well controlled. Very slow for a few seconds. Steep grade. 1-3mph. Rocky.
Its like the brakes release. RPMs climb rapidly. Have to apply brakes. Cycle repeats.
Not a smooth typical controlled RPM climb going downhill in any other 4x4.
Went up in the mtns like ive done many times. Roughly 40 to 60F so no shocker temp.
Temp just didnt show.
Had to shut down engine and restart to get it to read again.
