 We purchased our Expedition in 2012 w/only 50k miles.  The AC compressor went out w/in a week which I put on the dealership we purchased it from.  We had purchased a warranty for this SUV which covered the repair and pretty much paid for itself immediately.  Only other repairs were the ball joints, axle bushing, and alignment at 82k miles (warranty covered).   Finally rear bearings, axle seal, front differential, pinion seal, and cam adjuster were replaced at 100k miles (warranty covered).  Tires were replaced at 107k miles, but we only got 4k miles on them before loosing the SUV to a deer.  We owned the SUV for 4 years and it served us well.  I would recommend this SUV.  We have purchased a warranty on all of our vehicles which has paid for itself every time.  The transmission was was slipping a bit prior to the deer strike, but it was not to the point where I felt it needed to be addressed.  Cold weather appeared to bring this issue out.
