Mine is the same model as yours, manufactured in April 2010 and has that high pitch whizzing sound at around 140km/h. Scheduled to dealer the coming week, see if they will be able to solve that problem. In case they say they do not recognize the problem, does anyone has the Techinical Service Bulletin ID#?
