Have any of yall seen anything like this on your shots before? I noticed it today and have went back and looked at my shots and just below the focus point there is always a hot spot or dead pixel. Is this common?

'Hot' pixels that are too bright in low-light situations are fairly common. My D100 had one that would appear in shots at around 1/30 sec, f/2.8 at ISO 200 when it was new, and has subsequently developed a second that's slightly more noticable. They're not much of a problem to me since I usually shoot in good light where they aren't visible.
'Stuck' pixels are a different matter; here you have a pixel that always produces the same output no matter how bright the scene is. This shouldn't happen: if a new camera has such a problem then you're perfectly justified in asking that it be replaced.
If your camera develops either of these problems then Nikon can 'map out' the offending pixel - meaning the camera's software ignores the faulty pixel and calculates a substitute value from surrounding pixels of the same colour.
Personally I've had the 'hot' pixel problem to a greater or lesser degree on three of the five digital cameras I've owned to date. Ironically the best camera by far in this respect is my D1: it has significant low light 'patterned' noise problems, but it's remained completely free of 'hot' (or even 'warm' ) pixels.
