“Transmission leaks oil/gas pedal is very stiff & hard to press/ door locks keep going up and down when using remote control/ rear washer hose to rear wiper had to be replaced/there is noise in the left front wheel, and disc backing plate is bent and brake pedal is stiff when trying to stop.”
NHTSA complaint #873637, filed 2000-10“Model ml320 the cruise control stalk on this vehicle is located directly above the turn signal stalk. The cruise control & turn signal stalks are of equal length. When making a right turn, and engaging the right turn signal, it is likely to also graze the cruise control stalk, which engages the cruise control, and sets speed. This is especially a problem at night, as the cruise control stalk is not lighted. All other Mercedes-Benz vehicles currently produced have a cruise control stalk that is shorter then the turn signal stalk. The ml320 is the exception. …”
