Recall summary

A brake booster enhances the performance of the vehicle’s brakes. This makes it easier for the driver to increase the braking force without having to step too hard on the brake pedal.

In the affected vehicles, the brake booster is encased in a rubber sleeve for aesthetic purposes. Due to a supplier error, water can enter inside the sleeve, causing the brake booster to corrode and leak. 

This could require the driver to press the brake pedal harder than usual to slow the vehicle down. In some cases, the brake pedal may disconnect from the braking system, preventing drivers from stopping the vehicle altogether.

The component involved in this recall is the brake booster with multiple part numbers including A1644310427, A1644310527 and A1644310627.

Recall risks

Brake failure may make it difficult or impossible to slow down or stop the vehicle. This significantly increases the risk of a crash or injury.

Warning signs

Drivers might observe a hissing sound when pressing the brake pedal. They might also notice that the brake pedal is not as responsive as usual.

Other Mercedes-Benz recalls 

In March 2022, Daimler announced a recall of 28,743 Mercedes-Benz Metris vans over over reduced braking performance that could increase the risk of a crash.

Mercedes-Benz recalls also include certain models of the Mercedes-Benz GLE Class spanning the 2020 to 2022 model years and equipped with mild-hybrid powertrains, which were recalled earlier this month because of the risk of fire.

The repair

Dealers will remove the rubber sleeve to prevent further corrosion and inspect the brake booster housing. Vehicles with minimal corrosion can still be driven normally “for up to two years” before requiring another repair. Vehicles that fail the test must have their brake boosters replaced.

Affected owners are advised not to drive their vehicles. They will be notified of the recall by May 27, 2022.
