The 2012 Mercedes-Benz R350 has 3 recalls, the most serious being a driver's frontal airbag inflator that can rupture and send metal fragments into the cabin, risking serious injury to the driver or other occupants.
The brake system carries a significant concern as well: moisture can build up inside the brake booster housing and cause corrosion that weakens or eliminates the vacuum-assisted braking force. When this happens, the brake pedal requires considerably more pressure to slow the vehicle, and in severe cases the brakes can fail to respond adequately, raising the risk of a crash.
