Mercedes-Benz is recalling certain model year 1999-2002 M-class and model year 2000-2003 M-class amg vehicles. The cruise control system in the affected vehicles allows the driver to disengage the system in a number of ways, including tapping the brake pedal, using the cruise control stalk, or braking the vehicle enough to reach a certain rate of deceleration. Mercedes-Benz has determined that under certain circumstances use of the brake pedal may not automatically disengage cruise control as expected by the driver, although the other means of deactivating cruise control remain fully operative. Specifically, where the driver pumps the brakes rather than applying consistent pedal force, the level of force required may be unusually high.
