Nikon D5100 Black Pictures Issue?

I'm considering buying a Nikon D5100 today. I have done a lot of research and I think this is the perfect camera for what I need. However, I keep seeing consumer reports about a black picture issue. After 3-8 months of use some people report that the shutter becomes stuck. They will send it back to be fixed, only to have this issue happen again.

Does anyone know anything about this? Was it a 'bad batch' vs.a manufacture error.

Is it still worth purchasing or should I keep looking? Opinions?

Thanks!

Added (1). I found these negative reviews on Amazon (http://www.amazon.com/Nikon-16-2MP-Digital-18-55mm-3-5-5-6/dp/B004V4IWKG)

It also have many more glowing reviews then bad ones. So I'm just not sure if its worth the risk…

The D5100 suffers more from inexperienced users than any real problems. Many never take their camera out of the program mode and when they do use it in the manual mode, neglect to notice the light meter in the viewfinder.

Any "stuck" shutter would produce overexposed image (pure white, not black)

I have a colleague who uses a D5100 and she has over 250, 000 shutter cycles on it and it is still working just fine.

Where did you read these "complaints"?

I always ready all the reviews I can find when I make a major purchase like this.

For instance, I found it is a good idea to keep my water tank on my rower covered when not in use so the water stays fresh longer.

I learned that (and it makes sense) a 100mm marco lens enables you to be further back when photographing flowers., than a smaller size macro. But I was taken in by the price on the smaller macro being half that of the 100mm macro. Result I can't see myself on my knees with a special small tripod trying to get the shot every time I photograph a flower.

In regards to the Nikon D5100, if I read this, I would run in the opposite direction "quick as bunny!"

It probably happens on users who don't know what they're doing. At any rate, did you know the D5200 is out? It would be a better choice.
