It's just surface rust and as justn said its normal. When you drive and apply the brake it will be removed.

Driving in rain will cause surface rust overnight. It is completely normal. Even high humidity can cause it. There is nothing a dealer can do and even replacement rotors will rust virtually as soon as they are installed.

As others have said here, surface rust is totally normal on rotors. As long as you drive the car once in a while, the pad will clean off the rust and remain operational.

My car also has the same visible rust since I bought it. It cleans itself after a short drive. Somehow I notice it more on this car than the others...???

That may be a factor; but even independent of that I feel there is more rust in that area in an RDX compared to other cars .
While I was checking this out today I noticed that the rear wheel has only one rotor whereas the front wheel has two rotors! I guess that's how it's supposed to be in RDX.

Guessing he possibly means solid vs vented rotor along the circumference?

I'm sorry if I was not clear enough in what I'm trying to say. I feel the front and rear rotors look different. The front one seems to have two rotors attached side to side but on the rear there is only one rotor. May be its just that the shape is different. I will post some pictures in the evening.

^^^^ because the fronts do most of the braking.

This is what I was referring to. The front ventilated rotors (the first two pictures) look like two separate discs welded together by metal struts whereas the rear is just one disc. Notice the rusted look in and around the rotor area. As you guys already know, this in no way affects the safety or performance of the brakes whatsoever.

Picture of rotor from another car (MB) of similar age and use. The rotors as such look similar but the area in general appear clear of rust.

The outer edge and inner edge can have surface rust. From those photos, the braking surface is clean and shiny and look fine. If the braking surface had rust and corrosion after using the brakes, then you could have a caliper that was "hung up" and not sliding on it's caliper pins.
