I had this problem twice within the last two weeks!!! I have a GLE 350E, check engine light was on 1st week in Nov, I didn't get an appointment until a week later, by then the light distinguished but kept my appt with the dealer. The dealer ran some test and stated I had an O2 sensor issue which was "fixed". So now yesterday, Dec1st the check engine light is back on, and i have an appointment next week. I'm beyond frustrated!!!!!!
