Another thing to mention is the air pressure in the tire's. And being from Ohio I know you know how temperature effect's it . My low pressure light went off on mine last Nov. a few days after I got it . Checked the pressure and was around 30 . I keep a good gauge in my car. So I took it to the dealer since I was close by . They said needed to be 33 . And it takes a few miles of driving for to reset after airing up . Haven't seen where anyone else has a problem with it . But my dealer said they'd had several come in think they had a problem . Just needed air. Your temperature dosn't swing as much as it does here though. I average 20 to 21 mpg and a best of 26.78 so far. Low of 17.5 . Have fun .
