If it were my D4 I would not be happy with Nikon either -- I would use this inexpensive but precise tool. It's about $70 and easy to setup and use. This will precisely measure and quantify the problem.

I would capture some images with the focus compensation set to zero and see what I got before sending it back again. Then, if the focus is off I would probably adjust the compensation rather that have a tech handling my camera, and if I did need to send it back I would include the focus test images and a full write-up describing what I think is wrong with the camera.

At the price of a D4 I would expect nothing short of a precision instrument. Possibly, if you document the fault(s) well enough and write a cover letter you could convince Nikon or your local dealer to replace the defective camera with a new one.
