    Recently had the 15k service done at the dealer, and am now getting 5 MPG less than before it was brought in. Brought it back to the dealer, but they can't find anything wrong. Has anyone else experienced this? Any ideas?

    Thank in advance...

    Perhaps they reset the computer and it reset the "memory" and therefore forgot your driving style? If this is the case, then it has to relearn your style; maybe it hasn't completed?
