Auto focus problems with D7000
Can someone help me understand why my D7000 while in auto focus mode has trouble focusing indoors. I frequently find that I will press down part way on the button to focus, it will focus and then blur out. I end up having to use the manual focus ring and by then the picture is gone. I first thought it was lighting or difficult patterns per the manual. But just tonight while in our sink bathing our granddaughter with a light overhead, experienced the same problem. Very frustrating. My daughter's cheaper Sony A55. camera works so much better.
This seems very basic and something that should not be happening. I have read about back focusing, but this does not seem to be the problem..
I am using a DX 16-85 1:3.5 - 5.6GED lens, which is my everyday lens.. I have experimented why fewer focus points and different AF modes.n doesn't seem to have any impact. My hope was that with fewer focus points and AF-S mode that I could make the problem go away.
I am a novice wanna be, but this problem is highly irritating.. I am sure that I am simply dong something wrong... Help please!

Lens properly mounted and contacts clean? It sounds as though you should have adequate light for focusing, but is the AF-assist on (menu setting a7)? Will it focus in live view mode? Live view uses a different focus system than using the view finder. If it won't focus in live view either, there may be an issue with the lens. Otherwise, it may be worth taking the camera to a dealer or repair shop to have them investigate.

I appreciate all of the replies... First off, I do live view most of the time and that is where I have experienced the problem. Second, I do have the "built in AFAssist Illuminator" turned on. Third, I could check the contacts, but I had this problem right out of the box with a brand new body and lens. And lastly, yes I do have the "M/F" on the lens and the auto focus on the camera body turned on. All great suggestions to check!
I am going to try to replicate the problem in a more controlled environment and pay close attention to what is in focus, if anything, to rule out back focusing and to be able to better pinpoint what I am seeing and the camera settings at that time.. I only seem to have this problem indoors. Have never had an issue outside, so light must have something to do with it????
Again, I very much appreciate the replies and welcome any new suggestions.
As a side note, I have a friend who also has a D7000 and also has experienced this problem.. She shoots weddings, senior pictures,etc, and recently upgraded to a D610. Using same lens(as on the D7000 with the problem) with the new D610 and so far has not seen any out of focus problems. The problem aeems to be with the D7000 body..

Live view is your problem. It uses a completely different focusing system than the main focusing system, and is not nearly as good. Try turning live view off when you next encounter the focusing problems - I think you'll find that when using the eyepiece the focusing works much better.
I don't use live view much, but when I do I try to use manual focus whenever possible - it's much more reliable than the autofocus in that mode.
