The 2012 Mercedes-Benz GL550 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 passengers.
The remaining two recalls both concern the same brake booster defect: moisture can collect inside the brake booster housing and cause corrosion that reduces braking power or causes the brakes to fail outright, leaving the driver with little or no stopping ability.
