 Had such good luck with my 2006 Pathfinder that when the lease was up I decided on a 2010.  The engine is bullet proof.  All I ever did to my "06 was change the oil, replace the air filter and rotate the tires.  I never brought it in for any of the scheduled services and at 52,000 miles when the lease expired the truck ran as good as new. I never had any engine related problems. I think what partially sold me on getting another Pathfinder is the 3rd row seating in a smaller/sportier vehicle instead of being forced to buy a gigantic SUV like a Suburban.  The Pathfinder fits in my garage.  I have noticed a few improvements in the 2010 compared to the 2006.
