I've noticed with my 2000 Pathfinder LE that when cold, it won't shift into overdrive until engine is warm. A little frustrating when most of my driving is highway. Fuel economy is 15 city and 17 hwy. When pulling, I get 14-15 depending on how fast I go. The comfort is outstanding, not trucky at all. Feels like a dream to sit in. Heated seats will light your backside on fire.
I love the moonroof, the Bose stereo system, and smooth ride. All my friends love it.
I would recommend a more fuel-efficient engine. But in the midsize SUV market, good luck. Their all about the same. Except Dodge, their mpg is really bad. I had one, I know.
