I have the D800 and have it set for Focus priority. I use back button focus and shoot in RAW. Mine focuses very fast and have never experienced that problem no matter what lens I have on it, including the Nikon 24 - 70 f2.8. Sorry I could not help, maybe you should call Nikon.
On focus priority, the shutter won't fire until the camera is satisfied with the focus. You want the camera to fire when you push the shutter release. Set on release or whatever the option is called, but not focus priority.
