I have asked this before, but issue continues.
When the car is a idle and you move it, the power steering groans like an old dog, and you feel it in the steering wheel.
Two times (Random), it was so loud I thought the pump quit. I have taken it to the dealer and I'm told "They all do that". Note if you rev it up, smooths out, almost like the pump does not have enough flow at idle or they set the idle low to save fuel, or poor design, or the dog issue.
I have checked the fluid, even swapped it. No debris or smokey fluid.....
