Was wondering if anyone else experienced this issue or have addressed it.

When going at speeds of about 15-20 MPH, if i take a moderate to sharp left turn, I can feel vibrations in the steering wheel and hear a whirring/winding noise. This doesn't happen if the car is idle or if I take sharp turns at slower speeds, e.g. pulling into a space.

Anyone have any idea? It's a 2012 xS coupe so I can still bring it in under warranty conditions. Just figured I can give the dealership a head's up of what might be wrong.

Thanks!

My car only has 400 miles on it, but it is a 2012 G37xS Sedan, not a coupe.
The steering wheel vibrates during a sharp U-turn and some groaning occurs. The steering wheel is NOT at full lock. This occurred at about 5-10 mph.
I could not get it to replicate during right sharp turns.
The problem has occurred 3 times within the past week and I am unsure what the exact cause it. I first thought it was the power steering pump dying, but my car is new, so that is just odd. Then I just tried to give it the benefit of the doubt and that the AWD system was engaging. I tried tightening my lugnuts to the recommended 80 ft/lbs and I will see if it comes back. I hope it does not.

I am subscribed for further details.
