(1) Answer
First check the condition and level of the power steering fluid. The steering system could be flushed out and flushed until the fluid is clear coming out the return line to the reservoir as the wheel is turned from side to side with the engine running. Your vehicle also has electronic variable assist that may have a problem within its operation but the system needs to be properly diagnosed to see what is going on. Its foolish to speculate without doing proper diagnosis.
