Had been losing mpg for about six months (went down from average 28 to 21) and dealer said could not do anything for me. Finally, engine light went on and brought car back to dealer who diagnosed a faulty oxygen sensor. Dealer ordered part and replaced sensor couple days ago. Engine light is off but it will take several months to check the mpg. Improvement.
