I bought a new Breva in '04 and ever since day one I have had a high pitched whine in 5th gear witch started at around 45 mph and quieted down at around 70 mph or 78( according to the Maryland state police). I have around 15K on it now and nothing exploded but I'm wondering,is it an issue that will leave me sitting in the middle of Podunk some day? Thanks for your help.
