The 2009 Mercedes-Benz R350 has 3 recalls, covering two serious safety issues: a brake booster that can corrode internally and reduce or eliminate braking power, and a driver's airbag inflator that can rupture in a crash and send metal fragments into the cabin.
The brake booster issue involves moisture building up inside the housing, causing corrosion that can leave the driver with a significantly harder pedal or no effective braking at all. The airbag concern is separate: if the driver's frontal airbag deploys, the inflator can burst apart, with metal pieces striking the driver or nearby occupants rather than the bag providing protection.
