More than likely an issue with the motor/actuator on the side of the T-case.

Or it just need to be servicesd and you can reset it aswel that is a sensor located behind your grill you just unplug it and plug it back in that well reset it. On a 2012 that is how you do it

Dumb question but did you try engaging in while in 2wd going over 2-3mph?
This is when it should be engaged. Might wake it up. Owners manual says to engage it this way. Hope it helps

They tell you this because sometimes the gears won't mesh when nothing is turning.Square cut gears will sometimes just butt up against each other instead of engaging depending on position.
