Well this explains it. but even their techs don't know about this! Looks like I'll be trading them off for the new Nikon.
Good luck if you do that.
After my 3rd Nikon full frame DSLR failed on me at weddings, I ditched all of that product line and went to Fuji. Not because I was naive and thought Fuji would be problem free, just frustrated and time for a change.
My D3s (their flag ship for a short while) had 2 repairs at Nikon for a random locking up with ERR code on the top LCD. After 2 repairs and almost $900 (Canadian) it still wasn't fixed and Nikon didn't know what the problem was. The other 2 failed bodies (D700 and D610) both had different mechanical failures that each required approx $400 repair bills.
The grass isn't always greener on the other side.
Oh ... and a side note. When I got the D610 I had an incident where video I recorded did not get written to the memory card. I followed up with Nikon and they didn't know why that would happen. I later discovered that if the batter got low, there was a chance video would look like it was recording to the memory card but it wasn't! wtf From that point on I always made sure when shooting video for wedding clients that the D610 had a battery with more than 50% power. I was always worried that my video recording was in fact not recording after that. But I never had that video issue again.
