K5 Autofocus Malfunction Question

I'll be taking my K5 in for repairs next week for an autofocus problem. It is front focusing on every lens. I can switch to MF and dial it in, but when I switch back to AF and press the shutter halfway, it immediately goes out of focus. It is especially noticeable when I am shooting wide open. I am just curious if anyone has any ideas what the cause would be. Before I realized it was happening on all my lenses, I actually took in a lens for calibratiion. Thanks in advance for any ideas or suggestions.
