Service 4WD light

[Wookrystal]

Started getting service 4WD light a few months after having the 392, took it in to the dealer they kept it and changed out a part. A couple of month pass and the lights back again. It only comes on if I’m parked then I have to turn off the jeep then start it up again and move while it’s not on. If I try moving while the lights on it’s like there’s resistance. Anyone having this issue??

Buy an obd2 scanner, they are cheap as dirt and give you a code.

everybody should own one

Yes - had this issue - 2000 miles and 6 weeks after taking delivery. Was on a road trip (no off roading) and stopped at a dealership. They said it was a stored code, saw nothing to repair. 60 miles up the road, loud clunk/grind and end of trip.
towed to my local dealership (cost me $1600 which was later split with dealership and Jeepcares). 6 weeks later left with new transfer case. Came from factory with little(or no) fluid in original transfer case.
so - my advice - immediately check the fluid or take it to dealership to check. (This is a known issue with TRX and other 392s)
