On the GL450's three are 4 common issues that can cause this. Mercedes Benz has a recall for the failure of a driving pin that controls power steering pressure. Your local dealer will need to be contacted to see if your vehicle is affected. Another one, is the power steering pump. According to Mercedes the pump pressure should be checked and at least 1500 psi should be present at all times. Another possibility is the U-joint that connects the steering column shaft to the steering rack. This joint can bind causing the steering to be hard or notchy at times. A last thing to consider is a failure of the power steering rack. This is a difficult repair since the steering rack would need to be removed. You may want to enlist the help of a mechanic, like one from YourMechanic, who will have the equipment and expertise to assist in the diagnosis and repair of your power steering going out.
