Are you guys referring to the whine when you start up in ACC? Do you hear the whine for a couple of seconds when you go back to OFF?
It could be the drive-by-wire throttle. Our cars, like the G37, still have e-throttles. It does a self test when you first turn on your car, and you can hear it go back to home position when you turn it off.
That's the only whine I would notice besides 1/2 gear whine lol.
