My D800E was shipped by Amazon in July, 2012, and had a left-autofocus calibration problem. (Right autofocus, too, for that matter—although it was not as severe and was limited to the very rightmost sensors.)

I followed Ming Thien's and Thom Hogan's reports on the issue, and several other less-reliable or, at least, more speculative ones. Ming's experience wasn't directly relevant to me because it appears the East Asian Nikon repair centers had procedures in place to recalibrate the D800/E bodies before the American repair centers did. (Ming is based in Kuala Lumpur.) I'm in Washington, DC, and when Thom Hogan reported that Nikon's repair facility in Melville, NY, was finally able to recalibrate the bodies properly, I uploaded test shots made according to his instructions to Nikon-USA's customer support website.

The Nikon support reps asked for an additional round of tests (less rigorous than the ones I had performed, in my opinion), after which they told me all my image files had been forwarded to Japan for evaluation. A week or ten days later, I was instructed to send the camera to Melville, which I did.

The recalibration seems to have worked fine. Only problem is that I've had to change the fine-tuning adjustments for all my lenses; fine-tuning really seems necessary on the D800E. But now I can use the sensors on the left and right, and get results using PDAF that are very close to the results with CDAF.

I wouldn't bother to send in a camera that didn't exhibit this problem: you will definitely know it if you have it, even after rudimentary comparisons of the left, right and middle sensors between CDAF and PDAF. But if your camera does need recalibration, it appears Nikon can do it now (at least at its East Coast facility in the United States).
