Mercedes-Benz USA is recalling certain 2006-2012 ML-class, GL-class, and R-class vehicles due to possible corrosion in the brake booster.

According to the National Highway Traffic Safety Administration (NHTSA), moisture may accumulate and cause corrosion in the brake booster housing unit which can result in reduced brake performance or brake failure, increasing the risk of a crash.

Owners are advised not to drive their vehicles until the remedy has been performed.

To check whether your vehicle is part of this recall, it's advised to enter your 17-digit vehicle identification number (VIN) here, or call their customer service at 1-800-367-6372. Owner notification letters are expected to be mailed May 27, 2022. 

To remedy the situation, dealers will remove the rubber sleeve, inspect the brake booster, and as necessary, replace the brake booster at no charge.
