Sound goes away at end of clip.
Sound familiar to anyone?
Should i wait till it happens again and kill a/c as well as turn steering wheel?

It's hard to tell from the video, but it could be the secondary air injection pump, which is part of the emissions control system (P/N 000-140-57-85). It'll whine for ~30 seconds when the car is first started, then you can hear it spin down when it stops.

Check the Alternator and Drive Belt. That is often the cause of "whine".

Star power is correct

I asked my dealer about the whine. It is the air injection when you first start and then it will go away. It is supposed to do that
