"Moisture may wick under a rubber sleeve that is installed around the brake booster housing for aesthetic reasons. This might result in corrosion in the joint area of the brake booster housing." — Mercedes-Benz
If enough water causes enough corrosion, the brake booster can leak fluid and cause reduced braking or even brake failure. The chance of complete brake failure is increased if a hard braking event damages the brake booster.
A Mercedes driver should be on guard for changes to the brake pedal or air/hissing noise when applying the brake pedal.
There have been no reports of crashes or injuries in the U.S.
Mercedes will mail brake failure recall letters May 17, 2024. Dealerships will remove the rubber sleeves, inspect the brake boosters and replace them if corrosion is discovered.
Owners may call 800-367-6372 and use recall number 2024MMNNNN.
