If this doesn't answer your question, provide a bit more detail on what you mean by adjusting by itself. Might also give the build date off the door sticker as there appear to be a few variations.
The lowest possible height for driving above 15 mph is Aero mode, available in Sport mode or any time the vehicle is travelling above a couple mph/time thresholds.
Below 15 mph, you can run in park/exit, which is as low as it goes. If yours tends to go to "raising" and stay there, there's a TSB for a reflash that mostly works, or you can just drop into "sport" mode for a few seconds and then back to normal.
As you park the thing, if you hear the ratchety sound after a bit, that is just the vehicle adjusting its height "for appearance purposes" We could argue about that being busted or just wacked out design.
None of these have any effect on being able to drive in the lowest possible height, which is aero. Just drop the thing into Sport mode and it will drop to aero. Sport also changes the 4wd front/rear a bit, making it more like a traditional rear drive with a bit of front left. Sport also changes the shift points and speed, it holds gears longer, seems to definitely offer more engine braking, and speeds up downshifts for quick passes on mountain two lanes.
You should be able to get the Owner's Manual in electronic form at Jeep.com for owner's section. Hard copy will cost ya a small amount, but it is a tad large unless you have a lot of cockroaches to squash.
