The mirrors do seem quite large and I reckon will contribute to the wind noise.Sorry to hear about your troubles. I'll try to compare with my 500X 1.6 Lounge.
I never had any brake noise. But I do have wind noise, probably from the exterior mirrors and I've been told that many others have this noise at high speeds.
I don't have a problem with the pedals, never got stuck or anything else. The 1.6 is nice and powerful and always has power at the right gear. I also have great mpg (rest of Europe uses the other calculating method, so mine says 6 L/100km average).
I did find a small defect with the rear spoiler, which seems to vibrate at high speeds, probably something easy to fix but I haven't looked at it so far.
