Had the stereo and hvac off today and noticed a definite whirring noise when 4A was engaged. Putting it in 2a under throttle and the noise would disappear. You could also watch the power distribution screen and whenever power was going to the front the noise would be present, noise would go away when there was no power to the front/no throttle application. I wouldn't call it a grinding (again, I didn't even notice it with the hvac and low-volume radio on) but it was definitely present.
This is my first Ford and honestly I'm hoping to avoid the dealer altogether, so set me straight if this is a common thing for these.
