Faults:

Front axle seal.

Heater hose.

Air suspension.

Power running boards.

General Comments:

Pretty reliable, obviously bad on gas, comfortable for long road trips, lots of room for people and cargo. I expected the rear air suspension and power running boards to prematurely break when I first bought the car. Rear air suspension was replaced with regular shocks and power running boards were removed and replaced with side steps. I'm still waiting for the engine to develop its signature problems, but I've been lucky so far.
