I have a 2010 370Z NISMO with 25,000 miles on it. I have noticed a problem with the car trying to steer me instead of me trying to steer the car. I have had the frontend aligned and wheels balanced and it still continues. I have notice that the fluid in the power steering reservoir is bubbling furiously. Is this normal? Could this be causing my steering problem? Any ideas or suggestions? Take a look at this video http://youtu.be/4NxWRfnRzFg
