2006 Mercedes-Benz M-Class ML350 4dr SUV AWD (3.5L 6cyl 7A)
I have had this vehicle in to the service department for jerking transmission problems six times at two different dealerships. They claim it is a known problem and that there is a "software upgrade" coming from MB Corporate. The service experience and the lack of solution makes this my first and last Mercedes purchase. Too bad because we really liked the vehicle. Also, the check coolant light is on constantly. They told us it was an "electrical problem" and didn't fix it. The sunroof will not close unless you hit button two to three times due to a sensor problem.
