The 2007 Mercedes-Benz R350 has 2 recalls, both addressing the same brake booster defect where moisture builds up inside the housing, causes corrosion, and can reduce braking power or cause brake failure entirely.
Prior repair attempts did not fully resolve the issue, which is why multiple recall campaigns exist for the same problem. In either case, the real-world risk is the same: the brake pedal may not respond with full force, or brakes may fail to engage when needed, raising the risk of a crash.
