my wheels had similar "corrosion" look, but did not look anywhere near as bad as the wheel it the link above. You could hardly see mine and had to get real close, but since mine was going in for the IC pump and lower door weatherstrip rust, I thought I'd ask and they replaced them! IC pump should be in on Wed and they claim to have fixed the rust too! Not sure yet what they did for the rust since I haven't talked to the service guy yet.
