I just noticed I'm missing a lug nut cover on my passenger front wheel. I've had the car for only one week and its gone. I have a set of Grey 21" wheels and my covers are black. The friction fit on the covers are pretty crappy, a good stream of water while washing will make them pop off. Anyone else have this problem? Anyone found aftermarket replacements that fit? I'll see if the service center will give me a replacement.
