One thing that hasn't been mentioned is whether you are in a Basic Zone mode (which means you have to use all autofocus points), or whether you are in a Creative Zone mode (which means you can select an individual AF point).

What mode where you in, and if you did select an AF point, which one was it?

For most of the shots, I was using the middle focusing spot and re- composing. Then I tried using all the focusing spots. I also had image stabilization turned on.

I can see a little camera motion in the second one, but overall it does look like a significant front-focus problem.

Before I would send the camera and lenses to Canon, I'd do some controlled tests. That means camera on a tripod (so no recomposition), IS off, ISO 100 in Av at maximum aperture, flat target with good contrast in good light, disturb the focus then autofocus using Quick mode with the centre point on the target and shoot with a remote release or self-timer, repeat nine more, ten shots using Live mode with the box on the target, and compare typical shots (or compare the Live image using the EOS Utility). Post a couple of shots with EXIF intact and we'll let you know what we think.
