This bug svcks sooo bad. I'm at a point in the game where I'm just about to complete "Come Fly With Me". Once I complete the mission and move on, any save beyond that point becomes corrupted after I die or turn the game off. I've noticed that tons of people have this same problem. Is there anyone who's brought there game back to be replaced and found that the problem had ceased after using a new disc?

I made a post about this a little while ago. You seem to have had something very similar if not exactly the same thing I had. When you go into your Load Menu (select Load while in the main menu) and press whatever button you need to to select storage device (should be X). Reselect your storage device (I assume you were using your Hard Drive) and it will reload it. Keep reloading your hard drive until all the 'corrupt' files go away. This doesn't work for everyone but if it does work for you it should make your previously 'corrupt' files no longer unplayable. If it's not working after you reselected your storage device try leaving the Load menu and re-entering it. This may help. The you can start using your file like nothing happened. I had to do this plenty times from turning my game off and getting crap-loads of freezes and a few disc unreadable. New disc didn't too much. Made the game run smoother and freeze considerably less but I'm still thinking on what I'm planning to do with this. I also beat the game on hardcoe.
