Mercedes Recalling Almost One Million Cars Over Bad Brake Boosters
Over the weekend, Mercedes-Benz announced a global recall campaign encompassing nearly a million vehicles it believes could be afflicted with faulty brake boosters.
“We have found that in some of those vehicles, the function of the brake booster could be affected by advanced corrosion in the joint area of the housing,” the automaker explained in a statement.
While the issue is global, the United States is believed to account for roughly 300,000 units, with the National Highway Traffic Safety Administration (NHTSA) advising against driving any vehicle involved in the recall. Affected units will undoubtedly offer lowered braking performance and can even cause total brake failure in some instances. Rare or not, the NHTSA feels this one is simply too risky to chance.
Affected vehicles include GL, ML, and R-Class Mercedes-Benz products manufactured between 2006 and 2012 ( a comprehensive list is available here). U.S. regulators are basically going off the MBUSA recall report citing the possibility for moisture to accumulate and cause corrosion within the brake booster housing. The planned fix involves having dealers look at the entire unit and replace them “as necessary.”
Mercedes said there were no known injuries relating to the matter. However, the NHTSA is mighty concerned about a potential vacuum leak creating problems for people on the road. A leaky booster will probably result in a mushy or unresponsive brake pedal and longer stopping distances on the road. Due to the potential hazard (and risk of outright brake failure), the agency has advised all owners not to drive any model under recall until it’s been serviced.
Mercedes first noticed the issue in 2021, launching an internal investigation that fall. The automaker felt confident that the risk was sufficient to launch a recall by May of 2022 and made a formal announcement over the weekend.
Those concerned about their vehicle can toss their vehicle identification number (VIN) into the NHTSA database or use the recall campaign code 22V315000. Alternatively, customers can also contact Mercedes-Benz directly at 1-800-367-6372 or use the NHTSA safety hotline at 1-888-327-4236.

Kudos to Mercedes for the recall. These are old cars, long past the original leasee and cpo owner. Unlikely they'll gain new customers as a result of this. I recently got a recall for my 15 year old car for a PVC heater replacement, also due to safety risks. Carmakers aren't in the habit of doing things out of the goodness of their non-existent hearts or because it's the moral thing to do, but I will call out every time they do something good for customers who - as has already been stated - aren't really even Merc customers.

- FreedMike Can the final last call edition be the Secretary Special, with a V6 and a vinyl roof?
- FreedMike I’ve never heard of this so I’ll have no problem not attending.
- ToolGuy As I understand it, the Toyota Prius basically lasts forever because the engine gets a gentle duty cycle and the battery gets babied. This seems like the opposite of that.[Impressive tech, not for me, but then neither is the Prius.]
- Dusterdude Excellent work ! Your stories are always linguistically interesting . Even if you weren’t writing about a quirky car on a long and adventuresome journey - I know your write up would still be interesting ! ( I also have a Soft spot for large cars - as my daily driver is a 2000 Chrysler Concorde )
- MaintenanceCosts There have always been just two reasons to buy AMG cars: the menacing, hard-edged V8 warble, and the styling with subtle shapes but perfectly aggressive details. This is missing both of those things: the styling has gotten cartoonishly aggressive, and the engine will sound like a fart-can Civic. I don't understand why I should want it.
