What other conclusion can be drawn?
Did you try the AF several times to learn how it behaves?
I have an AF lens that doesn't hit it really under a few circumstances (this is Canon) but works very well for the rest of the time. I decided to live with that as the workaround comes quite naturally.
AF is practical but one has to be able to trust it - knowing what it can do. Then, of course, if it always sets the focus wrong I guess you have to get the camera fixed.
Good luck to you with all of that,
