The 2010 Mercedes-Benz ML450 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, risking serious injury to the driver or other occupants.
The remaining two recalls both concern the brake booster, and describe the same underlying defect: moisture can build up inside the brake booster housing, causing corrosion that reduces braking performance or causes brake failure outright. In practical terms, the brake pedal may feel less responsive than expected, or the brakes may not stop the vehicle as quickly, raising the risk of a crash. Prior repair attempts did not fully resolve the issue, which is why two separate campaigns address this same problem.
