I posted in a couple other threads til I figured I would just post a new thread. Is anyone having any problem with BMW's wheels corroding? I have an '08 328xi and the rear wheels have corrosion under the paint. BMW won't own-up and admit it's their issue to resolve since there is no way to know if I have altered them in any way since taking ownership. I haven't. I noticed this problem at about 8000 miles or so.

I've seen some posts about Lexus, and Mecedes having this problem.

Anyone else have any info that might help me out?
