Mercedes-Benz is urging customers of certain older crossovers to stop driving because of a corroded brake booster that could cause the brakes to fail, the automaker announced Thursday. The application and corresponding recall apply to 292,287 ML, GL and R-Class crossovers and SUVs from model years 2006-2012.
Recalls are common, but urging customers to stop driving is not. In affected vehicles, exposure to water in the brake booster housing can cause a gasket to corrode, leading to a leak in the brake system. Braking force can be reduced, forcing drivers to press harder force the brake pedal to slow down and stop. . In rare cases, Mercedes said, it may be impossible to stop if there has been severe corrosion. The risk of a crash or injury would be increased, although Mercedes said it was not aware of any known crashes or injuries related to the issue.
The emergency brake pedal is not affected and could be used in the event of a regular brake pedal failure. Mercedes will provide free towing of affected vehicles to service centers. Dealers will inspect the brake booster housing and replace parts as needed. If the part cannot be repaired immediately, Mercedes said it will help “coordinate an individual solution for the customer, including alternative mobility.” Most likely it is a loan.
