With the lens off of the camera, the mirror operates just fine. But with the lens mounted, it gets caught up. Now, when I press the lens release button and twist the lens like i'm getting ready to pull it off, at the end of the lens turn before it comes completely off the body, is when the mirror falls back into place. It's really weird. I am going to go to a local camera shop and test out a different lens, see if that cures the problem. I will keep you guys informed. I was surprised as well that Canon sent the body back with the same problem I sent it in with.

Sounds like the lens is the culprit. I wouldn't continue to use that lens...or twist it undone while the mirror is stucked up there...you may damage something. The nifty fifty is plastic. I've had some experience where the rear mount became distorted after some rough handling. Not me of course.
