Driver's Side Lean

I've got a 2008 Escape, 2wd, 3L, auto. Of course I didn't notice this before I bought it but once I had it home I saw that when standing at the rear of the vehicle there is about a 1/2" lean to the drivers side of the vehicle. Has anyone else run into this before or have any ideas. Took it to the dealer and he's trying to blow me off.
