The surface changes on the metal appeared similar to what some F30 owners were posting, albeit a lot less significant. Maybe this just represents the initial changes prior to having obvious rust? I agree that I don't see any rust at this point. However, the included photo shows areas of brown/rust starting over some oxidized metal from an image in the F30 post. This seems plausible, but I don't have a doctorate in materials science or anything. And yes, there are a lot more important things in the world to worry about. I do have to say though, that would never expect any new BMW to ever have any issues like this, but maybe I am being naive.
