The 2011 Mercedes-Benz ML350 has 3 recalls, the most serious being a driver's frontal airbag inflator that can rupture in a crash and send metal fragments into the cabin, posing a serious injury risk to the driver and passengers.
The remaining two recalls describe the same brake booster defect and should be treated as one issue: moisture can build up inside the brake booster housing, causing internal corrosion that reduces braking force or causes brake failure entirely. A driver pressing the pedal may find the vehicle takes significantly longer to stop, or that the brakes do not respond as expected.
