Severe corrosion due to extended time in the field and prolonged exposure to water may lead to a leakage of the brake booster, thus reducing the braking force, leading to an increase in brake pedal force required to decelerate the vehicle and/or a possible increase in stopping distance.
Moreover, due to severe corrosion, a particularly strong or severe braking manoeuvre may cause mechanical damage to the brake booster, preventing the vehicle from decelerating through the service brake and thus increasing the risk of an accident.
The Mercedes-Benz GL vehicles affected by this recall were manufactured between 14 January 2004 and 31 August 2015.
