Rust on brake rotors
My 2014 RDX has rust on the rotors (non-pad contact areas obviously). The first car to do this. Eventually, the rotors and holders will disintegrate. Anyone else with this rust?

LOL, seriously?
Every. Single. Stock. Car. Has. This.
Brakes will eventually disintegrate? Yes, I'm sure the 3/8" thick iron will rust away in no time
sorry, I don't mean to be harsh, but like I said, every car has this happen. It's totally and completely normal. You can avoid it by buying aftermarket rotors that have the hub powder coated.. It looks good and keeps the rust away, but manufacturers don't do this because it isn't necessary, in terms of reliability or longevity, by any stretch.
If you think the brakes look bad, you won't want to look at your suspension arms. Eventually they'll be thoroughly covered in rust. Unless you're willing to powder coat your suspension and hardware, there's nothing you can do.
honestly, for the brakes to disintegrate, it'll take at least 60 years, and that's in a heavy moisture and salt exposed area of the country. You have nothing to worry about, I assure you!
if you want to keep things looking good, consider painting your brakes with high temp paint, or powder coating them (powder coating isn't cheap though).
best of luck and happy AZ browsing!

Where do you live? Like what state and/or city? That will have an effect.
This same topic has come up several times, recently, on AZ. I assure you, this is completely normal.
Manufacturers use cast iron for suspension and brake components, because it's cheap. While it may start looking ugly sooner than later, it will never lose it's functionality. I'm curious what other brands you've owned in the past. Maybe some higher end brands do coat their bits and pieces, but from the half dozen various Honda/Acura products I've owned, plus the easily 40+ Honda/Acura products friends and family have owned, this is completely normal and I've never come across either Honda or Acura coating their bits. The more we know about where you live (not your address, of course), what you've driven, how new/old each vehicle was, the more accurate answer we can provide back.

It really just is surface rust. Over years, it starts to penetrate deeper, but you'll never suffer failure. I've driven the living hell out of 20 year old Hondas, that were rusted to death (with sweet, modded engines 
), and never suffered a failure. I know of no one who has either. Otherwise, it'd be common place for old suspension bits to replaced eventually, but many people will roll on the same ones for the life of the car.

me too
I have this also. I dont drive every day, so the car is static, sometimes 4-6 days in a row, most weeks.
I thought the lack of usage, was the primary reason that I see this. Mostly on the rear rotors

Yes, every single car made. All it takes is a car wash or a wet night to form.
Some wheels will show the rotors more so the rust is more visible but you can bet your last dime that ALL of your previous cars had this - you just didn't notice it.
If you don't believe that then you fall into one of the categories below.

I think the OP is right in noticing that the rust appears more on Acura than other premium cars. In fact I just conpared it with a Mercedes E class which has almost no rust at all (talking about the non contact areas) but the RDX has thick rust on the edges. Both cars are of similar age and use. It's a cosmetic issue for sure and could be addressed by one of the above mentioned measures. Mercedes surely uses a higher quality whatever so that there is hardly any rust at all.

I'm glad OP had much to contribute after his initial post 
But apparently we are all dumb and Acura should be equal to, or better than Mercedes, at 50% of the cost.
