Since the day I purchased the vehicle, the driver's side exterior mirror is being shaken by wind buffeting at speeds above 60 MPH. It's not enough to obscure the visibility, but it certainly a nuisance, and is much worse at night with headlights behind us. The dealer said they attempted to order a replacement part but has been blocked from the claim by Mazda Corporate, who has identified this as a large-scale issue potentially affecting all units manufactured so far (design flaw) and is developing a fix with no current ETA. The correction will be covered under warranty if it eventually comes through. Until then, I have a shaky side view mirror at highway speeds.
