Hello everyone,

This is my first post here, I've tried many other places and no help. I have a 2011 G37S sedan and ever since I came back from a 4 hour drive it has a weird sound when accelerating that I cannot even explain. People have told me it has to do with the power steering or the pump or some pulleys but I honestly don't even know anymore. Any help would be greatly appreciated.

I attached a dropbox link since I couldn't figure out how to attach videos.

I didn't listen but maybe take it to autozone if you don't want to go to the dealer and ask one of them to help you identify the noise

 

That sounds like the noise mine used to make until the power steering reservoir was replaced (tsb for updated part). ALmost like a supercharger whine.
