My X definately doesn't like being switched from 2wd to 4wd LO in one sweeping push turn motion. I have to let it finish clicking in 4Hi before going 4Lo. I've had it stick a couple of times and give off a warning tone and the ATP light (If I remember right), 4WD light (Upper left) as well as the Display going completely out that shows the the 4wheels and T-case.

I had to shut it off for a few minutes to clear it last time. Off and restart didn't help.

For the first 9-10 Months I had it, it was throwing a P1000 (Communications) code. Ended up being a solenoid in the transmission. Liked putting itself in 3rd gear to take off. Talk about gen1 guttlessness. J/K
