Brake booster failure, this vehicle is exhibiting the exact same symptoms as described in recall campaign: campaign no. 2024050001, may 2024 all mercedes-benz centers subject: model gl-class, ml-class, and r-class (x164, w164 and 251 platform) model year 2006 – 2012 inspect brake booster – without pedal rework mercedes-benz ag, the manufacturer of mercedes-benz vehicles, has determined that on certain my 2006-2012 ml-class, gl-class, and r-class (164 and 251 platform) vehicles, the function of the brake booster might be affected due to advanced corrosion in the joint area of its housing. After extended time in the field and in conjunction with prolonged water exposure, this corrosion might lead to a vacuum leak at the brake booster. Loss of braking power puts me and everyone I am near while operating this vehicle in eminent danger!! this problem has been inspected and documented by Mercedes Benz of macon GA. 9-3-25 there were no warning lamps or messages present.
The contact owns a 2013 mercedes-benz Ml350. The contact stated while driving approximately 35 mph as the contact depressed the brake pedal, he felt that the brake pedal was soft and he had to depress the pedal with more force to stop. No warning light was illuminated. The contact had taken the vehicle to an independent mechanic where it was diagnosed and determined that the brake booster needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 199,000.
The brake booster failed while driving and I almost got in an accident. The brakes did not fully work and started pulsating almost like if the antilock system engaged. The brake booster was leaking air around the piston that attaches to the brake pedal. You could hear the air leaking when the pedal was pressed. It has been repaired at he mb dealer for about $2300. There were no indications of a malfunction, no lights or errors showed up.
I keep experiencing the "pre-safe limited" warning. The car break starts fading, and the check engine light remained on the working conditions. This situation is so unsafe because the car becomes heavy and the steering turns hard to maneuver.
