Moisture may accumulate and cause corrosion in the brake booster housing unit, which can result in reduced brake performance or brake failure.

Reduced brake performance or brake failure can increase the risk of a crash.

What to do

Dealers will remove the rubber sleeve, inspect the brake booster, and -- as necessary -- replace the brake booster. All repairs will be performed free of charge. Owners are advised not to drive their vehicles until the remedy has been performed.

Owner notification letters are expected to be mailed on May 27, 2022.

Owners may contact MBUSA customer service at (800) 367-6372.
