I resolved the no power to the steering issue (EPS) months ago after transfer case neutral, 2021 Grand Cherokee.
Once the transfer case is re-engaged and in gear, and the vehicle is turned off, power is still showing on the transmission lights by the shifter for a time. This tells the EPS to not engage steering assist (EPS thinks transfer case is still in neutral).
If on the "radio" head unit, under key off options, key off power delay and headlights off delay are enabled, add that time to key off (unless you open door to kill the delay time). In addition another 15 to 30 seconds of key off still required before lights on transmission display are off.
By setting the head unit key off options, key off power delay and headlight off power delay, to zero seconds, then 15 to 30 seconds of key off is enough time for the lights on the trans display to go out. At that point restarting the vehicle, EPS power steering works correctly.
So it is a timing issue of how long the Jeep must have no power before EPS steering assist works again.
Multiple restarts do not work to reset the EPS unless the total time off is met first (on one event).
When you re-enage the transfer case into gear, you must turn off the Jeep until the lights by the transfer case go entirely out. At that time the sterring will return to normal.
Try it and report back here.
