I've searched and found a few threads on this, but I didn't come across any instances where somebody has said they contacted Tesla to get the noise fixed and whether it was actually fixed.
My S85 (late 2014, with Autopilot) has the noise and it's evident between 80%-100% pedal. It's not the cool futuristic whirring sound, it's the steady tone that sounds like a tortured muppet crying for help.
I'd contact the SC to fix it, but first I want to make sure it's somebody that can actually be fixed.
It seems to be an issue with the larger rear motor specifically, as the noise can even be heard in this P85d launch video: Tesla Model S P85D AWD and auto-pilot demo - YouTube
But it's even worse in this S85 test drive video:
