Ours is a noise you cannot miss, anyone who has been in our car ask what that sound is and that its giving them a headache. Also the techs at Nissan heard the sounds and documented that they heard it.

But yes it is the same way, it happens when you raise the RPMs, either while driving or in neutral.
