The only thing i have wrong that has been mentioned by others is the fuel tank burp. If i let the tank fill until the pump shuts off, a bit spills out (maybe 1-2 cups) It hasnt been recalled that i know of so i havent got it fixed as it requires replacing the entire tank. I just look at the fuel level before i pump so i know how many gallons i need to put in and shut it off manually (16 gallon tank). The only way you will find this problem is to fill it up.
Other than what marlon mentioned, the steering wheel changed in 2011 models, there are also a few trim levels not available in the earlier years (jet, renegade, arctic etc) pretty much just cosmetic.
