2010 so you have the 4.0 V6. A very stout engine and will handle a lot of abuse (ran a 75 shot of nitrous
on mine, then pulled it off at 90,000 and added a supercharger and sold it with 203,000 miles on it with very few problems).
One thing to check right away is the plastic thermostat housing. They are prone to leaks. Look at the back side and see if there is any evidence (you will see some dried coolant at the split). It usually splits on the back and spews coolant under your intake manifold.
Very often it is misdiagnosed as a leaking hose or a bad water pump. Easy to fix and takes about a half hour; there is a replacement aluminum housing available (check amazon and ebay). There is no common time frame for how long the plastic housing lasts. My 2006 went 199,881 miles before the housing split open and others have replaced it a couple of times in just 60,000 miles.
