All rotor surfaces rust. What I didn't like was the hub part rusting so I removed the wheel and painted the hub part. Looks much better now than the rust.
Yeah my hub part of the rotors have a ring of brown around it. I think I am going to get some of the Baer Decela zinc coated rotors. They look better than stock since they are drilled and slotted and they are zinc coated to prevent the rusting.
It is called Ferridation - Rust Fungus. It grows on Iron when combined with water.

Just like the others said it will disappear immediately after the first time you apply the brakes! The first time I noticed it my car was brand new and I was leaving work and happened to notice rust on the rotor I was thinking WTF, but then thought about it, rotors get hot from braking, and it was a humid day just made sense, so no worries

All cars rotors rust up on the breaking surface if not driven, but my rotors have rust outside of the braking surface and it looks like crap. I just left it at the dealer to see if they will replace the rotors. It also has rust on one caliper that I can see. My wife and daughter drive cheaper honda vehicles and their rotors don't have a spot of corrosion anywhere after years on the road.
A buddy of mine bought a hennesy camaro a couple months ago and the manual stated there was a brake "break in" session. Where you would progressively brake harder and harder about 4 times in a row. With a 5 min highway speed run to cool them off in between sessions. Is there something like that, that needs to be done to the challenger?
This procedure is called "Brake Burnishing." It is recommended for all new cars and if you get new rotors or pads.

This is not an issue. I can understand someone that doesn't know to be concerned about rotor rust, but like someone else said, you can wash your car and the next morning the rotors will have rust. It's a characteristic of cast iron.
I will say it's not as bad as the post that someone came up with in another forum. They complained (on a 4 door car) that when they rolled one window down it caused a severe "reverb" effect. Therefore their car must be defective. I believe it was a Lexus RX forum.
