The 2016 Mercedes-Benz GL450 has 5 recalls, the most serious being a loose front suspension bolt that can cause the wheel to track improperly and a separate front suspension oil leak that can start a fire if the fluid contacts an ignition source.
On the steering side, water can enter the electric power steering control unit and shut off power assist, making the steering wheel significantly harder to turn. A software fault affecting the airbag system can prevent the airbags from deploying correctly in a crash, raising the risk of injury to occupants. There is also a software issue with the vehicle's emergency call system: a timing error can cause it to report an inaccurate location when calling for help, which may delay emergency responders from reaching the scene.
