Mercedes-Benz recalls nearly 290,000 SUVs due to brake problem

Mercedes Benz GL Class

Mercedes-Benz is recalling nearly 290,000 SUVs from U.S. roads due to a potential problem that may result in loss of braking power.

The problem is because moisture can accumulate and cause corrosion in the brake booster housing unit, which increases the braking force when the driver presses the brake pedal. If this happens, the driver may experience reduced brake performance or brake failure.

LThe vehicles affected by this recall are the 2006-2012 Class ML, Class GL and Class R until your brake boosters can be inspected. Mercedes.Benz says that owners of almost 300,000 of its SUVs must be parked until further noticesince this failure can cause accidents.

鈥淚n rare cases of very severe corrosion, it is possible that a hard or strong braking application will cause mechanical damage to the brake booster, whereby the connection between the brake pedal and the brake system may fail,鈥 Mercedes said in its advisory. . 鈥淚n a very rare case, it would not be possible to decelerate the vehicle with the brake pedal. Therefore, it would increase the risk of a crash or injury. The foot activated parking brake function is not affected by this issue.鈥

Dealers will inspect the brake booster housing on affected vehicles. Vehicles that do not show advanced corrosion can continue to be driven without further action. Vehicles showing advanced corrosion will have an additional test performed to ensure the functionality of the brake booster. Vehicles that pass the additional test can be driven for up to two years, but must be returned for additional repair. Vehicles that do not pass the additional test will require a brake booster replacement.

Mercedes says early signs of failure include a soft brake pedal or audible signs of air in the brake system (pedal sucking, hissing, or wheezing noises are potential indicators of contaminated brake fluid).

Mercedes-Benz will notify owners by mail starting May 27, 2022. Owners of affected vehicles can call Mercedes-Benz at 800-367-6372.
