What you are talking about is misfocusing. If it is consistent as you indicate it probably is a problem with the camera. However before sending it in for service, check that it happens with all of your lenses. And make sure you are putting the proper focus point on the part of the subject where you want he camera to focus on. I presume you are taking about autofocus which brings up the idea that you should check and see if it does it when you focus manually. If it happens with manual focus too, it indicates that the focusing screen or the sensor is probably not in the correct position, definitely a camera problem.
You should know however the autofocus can only focus within the Depth of Field of the lens, which is something folks generally do not realize. That means your focus can be off quite a bit compared to measured distances and still be as accurate as the system is capable of especially with shorter lenses.

backfocus problems
Could someone please explain what this means? I have a frequent problem with my D where the focus is behind what I thought I focused on. Is that "backfocus"? I'm currently assuming this is my fault, though I haven't had this problem with Pentax film cameras.
