SO I've only had my QX50 Essential for about a week. This is my third Infiniti, having previously had 2 M37x's. While I am impressed in many ways, so far I'm very unimpressed with the gas mileage. I had expected something around 25 mpg in combined driving as they promote, but I'm seeing around 20. I'm surprised others are not commenting a lot on this, or is my experience, and that of you other 3 commenters so far, really unique? Hard to believe.
