Has anyone ever heard of one of these spoilers cracking? I have a crack on the front of the spoiler closest to the window. I think it looks like where the spoiler bolts down to the trunk. Just wondering if someone has ever heard of a spoiler cracking. I looked at the other side where it is bolted down and you can see a bit of a crease but no crack. Its been on the car since new so wondering if its just old or if its a commen thing.
