This sounds to be an electrical fault with a power steering system sensor or component that has failed.I have seen this occur before in the past.I have also seen the power steering motor/pump fail and cause this issue here.What needs to be done from here is to have the fault codes read out/checked with a fully compatible scan tool that can plug in and communicate with all computers in your model.Once this has been done any codes set need diagnosed to help locate and repair this fault here.
