Mercedes-Benz Says to Stop Driving These Recalled SUVs
The recall will fix an issue with the brakes that could lead to a crash if left unrepaired
Mercedes-Benz is recalling more than 292,000 GL-, ML-, and R-Class SUVs from the 2006 through 2012 model years because of a potential problem with the brakes. Owners of vehicles included in the recall should not drive them until the free recall repair has been performed.
According to the automaker, prolonged exposure to water could result in some braking components becoming damaged, which could result in either reduced braking performance or total brake failure. The driver may need to press harder on the brake pedal, or the brakes might not work at all.
Both of these situations can lead to a crash and potential injuries. Only certain GL-, ML-, and R-Class vehicles are included in the recall. The foot-operated parking brake is not affected by this problem.
Drivers may notice a change in the brake pedal feel and/or a hissing or airflow noise when applying the brakes, if the vehicle is developing the problem.
The automaker began its investigation in July 2021 after a report of a customer from outside the U.S. experiencing reduced braking during a stop. After conducting numerous field studies and tests, including discovery of a single similar situation in the U.S., Mercedes-Benz informed the National Highway Traffic Safety Association of the recall on May 5, 2022.
Mercedes-Benz says that there are no crashes, injuries, or deaths related to the defect.

The problem: Moisture may accumulate and cause corrosion in the brake booster housing unit, which increases braking force when the driver presses on the brake pedal. If this happens, the driver may experience reduced brake performance or brake failure.
The fix: The dealer will inspect the brake booster housing on the affected vehicles. Vehicles that do not exhibit advanced corrosion may continue to be driven with no further action. Vehicles that show advanced corrosion will have an additional test performed to ensure the functionality of the brake booster. Vehicles that pass the additional test may be driven for up to two years but must return for an additional repair. Vehicles that do not pass the additional test will require a brake booster replacement.
The stop-drive notice will remain in effect for these vehicles until the brake booster is replaced. In the event a repair is necessary and cannot be carried out immediately, an authorized Mercedes-Benz dealer will help coordinate an individual solution for the customer, including alternate mobility.
How to contact the manufacturer: Mercedes-Benz will notify owners via mail starting May 27, 2022. Owners of affected vehicles may call Mercedes-Benz at 800-367-6372.

Check to see whether your vehicle has an open recall: NHTSA’s website will tell you whether your vehicle has any open recalls that need to be addressed.
If you plug your car’s 17-digit vehicle identification number (VIN) into NHTSA’s website and a recall doesn’t appear, your vehicle doesn’t currently have one. Because automakers issue recalls often, and for many older vehicles, we recommend checking back regularly.
