Do new D800's have left AF problem?

Do old ones have a focus problem?

I have seen 109 images posted on this forum complaining about D800 focus where the photographer either ignored the guidance on how to get sharp focus on page 100 of the instruction book or, if testing an outer autofocus point, the target did not contain detail in the vertical direction needed by an outer autofocus point.

I have not seen any complaint supported with an autofocus target which would seem to be good enough to ensure reliable autofocus.

There may well be 1 or 2% of D800 cameras with a defect but, based on images posted on this forum, the biggest issue seems to be owners expecting autofocus to work good with a subject where Nikon caution AF can be unreliable.
