Nebuchadnezzar

Mine keeps opening up by itself. It's annoying to always reclose it and then next time I open the trunk, it's flapping around again. Kinda weird because I've never opened it on my own, except once just to see what was in there... so I know it's not from wear and tear.

Anyone else have this problem?

This just screams for duct tape

Get the door replaced under warranty

Mine was doing the same for awhile. It stopped abruptly for no apparent reason. I must have reattached it properly. Take a close look to see what you can do.
Awfully annoying problem for such a sophisticated car.

Mine is similarly loose, now to the point where I've just taken it out and leave it off. In the process of it popping loose and me trying to re-attach it firmly, I think the little clips and their holders have been damaged. I hope to get a new one installed correctly at my next service, hopefully under warranty.
