I agree with others about the smell. It happens with our '21 GC about 80% of the time but I have not noticed any abnormal tire wear.
What are your Power and Headlight Delay timer settings? The TPMS and other features may be related to the delay timer. I copied this from another thread on flat towing:
Thanks to a thread on the North American Grand Cherokee Association (NAGC) forum...
"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 the 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-engage 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 steering will return to normal..."
Tried this and it works every time. Short version recap:
- under Settings, Key Off Options: set both the radio and headlight delay times to zero
- after re-engaging the transfer case, turn the key OFF until the lights next to the shifter go completely dark. This means both the Yellow gear indicator light AND the Light Blue shift position background light.
