The problem may be your IS (Image Stabilization). After reading the article below I tinkered around with removing the lens, switching IS on and off and my lens was fixed thank God!

That particular dog likes to hunt, especially in low light, low contrast, or high f/stop setting conditions. At least, that is what my son tells me about that lens. It will also hunt and hunt when the camera/lens is tilted at angle, such that lens creep becomes an issue, too.
Try changing to a different lens, to isolate the problem between the camera, or the lens. You may also check the AF mode. If it is in AI Servo, AI Focus, then it just may try to continously refocus on moving subjects within the field of view. Set the AF Mode to "One Shot" to see if the problem goes away. Hope this helps.

Remove the lens and reset the camera or Clear all Settings in the menu. Always have IS off when you mount/dismount the lens.
