Why does my trunk open on it's own when I am driving. on 2011 BMW 528i

Sometimes when I am driving, usually city-lower speed and when it is raining, the trunk of my car opens on its own. I stop and close it. It will then usually happen again a few times. Then it won't do it for a while so I forget it. Then it happens again, but never when I am at the dealer. The dealership here is terrible and no one has been able to tell me why this happens.

If it is still under warranty, better try to get it fixed before it expires!
