A friend of mine has a new C6, and tinted all windows...

He just noticed that the rear window is starting to crack. Have any of you heard of this phenomenon?!?!?!?! Can the tint actually crack a window?

I've never heard of a window cracking from tint. The only thing I know to cause a window to crack aside from in being struck with something is when its cold outside and you heat the window to quickly.
