Default IS250 AWD Noise upon Acceleration?

Anyone else experience such a noise? Seems to happen only when accelerating, but the noise seems to dissipate when you let go of the accelerator pedal. Best way to describe would be a continuous whining noise.

I used to get the whine noise from my 06 Evo when I accelerated. It was caused by worn ring and pinion gears in the center diff. I highly doubt that is the problem in a new car, but it can't help to check out the diff since it is AWD.
