With the roof open, as I hit about 27 mph, there is an annoying wind noise/vibration. It peaks around 33 mph until it fades around 45 mph, which seems to be, that the wind noise covers it, but it is still there, if you are sensitive to it. I have looked into the accessory wind deflector but, it says that it will keep your hair from blowing around ... Not my concern. New issue for Dealer. I would pay for the wind deflector, if I knew it would solve the problem. Anyone else experiencing this?
