I bought a new 320 about 4 mts ago & since then I've noticed rust building up on the wheel hubs. I mentined this to my local BMW dealer and was told that this was normal & was not covered under warranty. The rust is now very noticable and unsightly & I find it hard to believe that its normal for all BMW's. Has anyone else had thi sproblem an dwhat woudl you recommend I do.

By wheel hubs are you referring to the brake rotors? If that is the case yes brake rotors wil get a surface rust on them that rubs off the first time the brakes are applied.

Not just the brake disks but the hub the wheel is attached to. I could live with rust on the brake rotor as you point out thi sgets removed once the brakes are applied.

This appears to be standard. It took me about 5 months before it started on my 2008 E92. Your only recourse is to remove the wheels and get out the wire brush and a lubricant and you'll be good for another 4 months. I'll be doing mine as soon as I get the mount jack adapter. PITA.

Did you complain to your dealer or BMW? I intend to give BWW HQ a hardtime on this sub standard quality.

rotor and surrounding area rust is environmental mostly- namely because the car manufacturers save money and don't paint or use rust-proof components. after u wash your car, u will notice that the rust is especially more prominent.

u can either drive around and brake hard to get rid of some it it, or opt to paint the rotor & chassis. painting is a pain in the butt tho, cuz u have to remove the wheels, calipers etc. and, u have to use paint that is formulated for it due to high temperature concerns.

on the rx-8 forum, a lotta guys have painted it themselves. and there are many threads with step-by-step instructions on how they did it w/ photos. a lot of them look absolutely fantastic after it's painted.

for me, i just live with it best i can. i usually wipe down the area as best i can after a car wash, because the rust comes off really easy when it's softened up with the water. then i drive around and brake hard a few times and then it dries.

in the end the pursuit of perfection is a bit of a losing game.
