Today I was driving in the snow when and idiot light came on,it was the one that looks like a little wrench on the left side of the dash,the manual said it was a AWD malfunction and to get the car to a dealer immediately -the car started shifting badly and hesitating. So I puled over and shut it down for a minute, then i restarted and the light was out and the car felt fine, Does anyone know if this is serious or just a little glitch? should I go to the dealer? Thanks

Hello all, I just bought a 2008 AWD fusion a couple months ago and I think my MPG is a little low, the computer is telling me 21.5 per gallon. I thought these things were good for at least 25 MPG and I do alot of highway miles. What are you guys getting? Thanks
