Could mean several different issues; mine did the same at first then the service engine icon would come on intermittely from day to day or whenever. You need to have your mechanic do a test to see what codes come up. Mine was the transmission torque converter seal. I elected not to have the dealership rebuild my transmission just service it (no metal in the old fluid) I lived with it for 6 years until my transmission started slipping 3 months ago. I was lucking the slip was only when I was in OD. I just had the work done this week and she is driving like a new car!
