You've written a complaint without any explanation. What does "exposed to moisture" mean and what do you actually think that weather and dust sealing is supposed to prevent?
I've watched photographers using Nikon and Canon pro bodies in all sorts of weather. The ones who don't understand that they're using a complex electronic and optical device in the rain, or who dunk one corner or one side, or who spill a volume of fluid onto the camera, or who repeatedly expose the camera to rapid condensation environments, end up with a dead camera. Nikon, Canon, Sony, etc. - it doesn't matter which sort of DSLR body it is, because they're all subject to failure in such conditions.
I'm not accusing you of doing anything dumb, just looking for some details beyond your "exposed to moisture" comment. If a seal has failed, Nikon should fix it under warranty. If you put the camera through its paces in a situation or environment in which it was not warranted to survive, it's your fault.
Nikon, Canon and other camera makers don't claim any of their DSLR bodies are "weatherproof" at all. They claim only that some of their camera bodies are "weather resistant" and that's true. There's a huge difference.
