Rusty wheel hubs

[Chrislo]

I've just noticed that the wheel hubs on my month old C3 Aircross are very rusty in places, is this a common issue on many cars nowadays, or is it something that should be attended to?
I tend to be quite fussy about maintaining and caring for my vehicles, and I must admit that is very unsightly, especially with the design of these wheels where you can see right into the hub.
Has anyone else noticed this on their vehicles?
Have attached a few images to highlight it.

All my cars had this Problem, so I think this is normal.

Thanks for the reply.
Perhaps my previous car wheels didn't have the same view into the hub as this one, as have not noticed it berfore? I will have to do a DIY job on them with a wire brush and silver paint!

You may have to use heat resistant paint as they get hot due to braking.

Same on mine and most cars I had. Nothing to worry about other than for aesthetics.
