The 2010 Mercedes-Benz GL550 has 3 recalls, the most serious being a driver's frontal airbag inflator that can rupture in a crash, sending metal fragments into the cabin and striking the driver or other occupants.
The remaining two recalls both describe the same brake booster issue and should be treated as one concern: moisture can build up inside the brake booster housing, causing corrosion that reduces braking power or causes brake failure outright. In practice, this means the brake pedal may feel less responsive or lose effectiveness when you need it most, raising the risk of a collision.
