When this happens, is there anything that changes it? For example, if you apply the brakes, does it change? Also, when it happens, are there certain elements which seem to be present? For example, the engine is cold or at an idle.
My first suspect is what is called a torque sensor. The power steering control module determines the amount of torque that is required needed to maintain the power assist. I will tell you that if it is the torque sensor or the PSCM, it should have set a diagnostic trouble code. You should be able to retrieve it with a scanner capable of reading such codes.
Let me know.
