Mercedes-Benz ML320 RecallsCruise 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.

Dealers will perform the repairs necessary to correct this concern. The recall is expected to begin September of 2011.
