Your car's fuel economy is significantly worse than expected — you're getting about 26 MPG instead of the advertised 36 MPG. You've been tracking your fuel consumption and consistently see this poor performance during normal driving. The dealer test drove the vehicle but found nothing wrong and suggested the issue might be your driving habits, which you don't believe is accurate. This could involve a fuel system component that's not delivering fuel efficiently or an engine management issue that may require diagnostic testing and potential repairs.
