Hood shakes: It becomes clear that people do have this but is it really shaking or can something be done with the rubber adjustments? I have seen, when a big 18 wheeler breezes by me that the hood moved ever so slightly, like the air moving over the hood is lifting it slightly. It is not that the hood is loose and can flap up over the windshield. I also think that paint colors could have something to do with it, with some paints and reflections it is easier to notice. Vibrating mirrors - I have the Canadian GS model and I noticed that cleaning the mirror inside the cover causes the mirror to move. It feels "flimsy" just one tiny push with a sponge and the mirror needs to be re-adjusted. I have not noticed vibration during driving.
To put this in perspective, I had a Hyundai SF where the hood moved much more than the one on the CX5, I recall driving through a storm last year and I thought the whole thing would rip off the car. I think these days the engineering of these steels and the need to make things light weight is for us consumers something to get used to. Remember that the materials are tested thoroughly under many different circumstances.
