Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
The most common caused for the type of problem you are having is in most cases caused by a failing power steering pump. In order to determine if that is the case you are going to need to do some testing starting with running a pressure test on the power steering pump as well as check for codes in the VES system. See the steps in the link below.
