The 2010 Mercedes-Benz GL450 has 3 recalls, the most serious being a defective driver's frontal airbag inflator that can rupture and send metal fragments into the cabin, risking serious injury to the driver or passengers.
The brake system also carries a significant concern: moisture can collect inside the brake booster housing, causing corrosion that gradually reduces braking power or causes brake failure entirely. In practice, this means the pedal may feel less responsive or the vehicle may take longer to stop than expected, raising the risk of a crash. Prior repair attempts did not fully resolve this issue, which is why it appears across more than one recall filing.
