I've never had the problem or heard of it. I do know if you don't get the two tabs on the back(near the power buttons) in properly and try to close it up you can possibly cause damage because the parts inside won't be lined up properly. Seems weird though, that plastic is pretty tough.
If you bought it locally I'd bring it back and see what they can do for you.
