Jeep Liberty is a very under rated 4x4. Real transfer case with 4lo, and the traction control on the later models works quite well and you can easily turn it off when needed. I've owned a 2012 for a few years and it was great on the beaches. I did lift it ~2" and put on larger tires, and it was very capable. What led me to finally sell it was the constant electrical gremlins that nobody could figure out. Even on the jeep forums it's all a mystery with no real solution, and there is no availability of parts.
If it's working for you, I would keep it and invest in the repairs for a bit.
