Something's came lose inside my Steam Controller?

As the title says, I believe something insidd my controller has came loose or broke. Everything appears to still be working normally, but there is something inside that is completely loose, and rattles around if I shake the controller. If I tilt it about I can also hear it move from one side to the other. I haven't really put it through excessive punishment outside of having it in my backpack daily, which I am careful with and don't throw about in any way.

Is there something I can do about this? Should I?

EDIT: Bugger, that spelling mistake in the title is going to annoy me to no end...
