Cruise Control May Not Disengage as Expected

It has been determined that, under certain circumstances, use of the brake pedal may not disengage the cruise control as expected. All other means of disengaging the cruise control should remain effective. If the driver were to "pump" the brake pedal instead of applying consistent force, the level of force necessary to disengage the cruise control may be unusually high. Dealers will perform the repairs necessary to correct this concern. The recall is expected to begin September of 2011.

Mercedes-Benz ML320 Reviews

Great vehicle. I have a 2002 ML320 with 440,000km. Use it cross country few times even drove it through Mexico. Currently, we just drove it to New Orlanes from Windsor Ontario Canada in Jan. 2016. I have done yearly maintenance at dealer since 2002 without any big problem. All parts are original. There are some repairs but they were minor. Love the car 100%. My next car will be Benz - M class. ...
We bought our ML brand new. Spent many weekends at dealer and TLC after warranty expired. First set of Dublop tires lasted 20K and driver seat heater overheated. I replaced windows switch twice, two door lock actuators, crank position sensor, transmission connector and power steering hose gasket. There seems to be a minor drain on the battery that I have to replace battery every three years...
