I am having the same issue with my 13" Macbook Pro Retina - Has been back to Apple 3 times and had the screen and chassis replaced. The issue was gone after the chassis was replaced which included batteries and now its back again 3 months later. Going in again tomorrow and demanding a new one as I have had enough of the issue, mine sits on a desk most of the time which is probably why the glue is letting go but if they cant engineer a laptop to sit on a desk then thats not my problem. Update: UPDATE: My Macbook was replaced with a new unit. Apple store believed this was the first time they have seen the fault lol.
