    Hello.
    I am new to this forum and have a question regarding my Mercedes ML 350 sport 2009.
    When I accelerate from a standing start it takes approx 5 or 6 secs just to get to 20 mph. As I am new to big SUV and even newer to automatics I am wondering whether it is me or I need to go back to my dealer for them to sort it if indeed it is a problem.

    I don't whether it is something that I should be using with the tripronic gearbox. Thanks

    Doesn’t sound right bud. I would take it back and ask them to check.

    Sounds like its in limp mode. My e350 gets to 40 mph in 1 snap of your neck.

    0-60 in about 7.5s for that car, I’d say.

    Something wrong there! In 6 seconds my old 320 is just about ready to break the National Speed Limit!

    Thanks to all for replies. There was a problem with a throttle sensor which the garage fixed FOC and now it goes like a bat out of hell. Thank you.
