The 2011 Mercedes-Benz R350 has 3 recalls, covering two serious safety issues: a brake booster that can corrode internally and lose braking power, and a driver's airbag inflator that can rupture and send metal fragments into the cabin.
The brake booster concern involves moisture building up inside the housing and causing corrosion that weakens or eliminates brake assist, making it harder to stop the vehicle. On the airbag side, the driver's frontal airbag inflator can burst during deployment, scattering metal fragments toward the driver and other occupants rather than providing protection in a crash.
