The hood fluttering I bitched about in my 2014 Mazda 6 review has been addressed by a service bulletin. Looks like the replacement of a cowl seal is all that's needed!
So if there's any 2014 Mazda6 owners with hood flutter above 68MPH (why so specific, Mazda?) call your dealer and tell them I sent ya! No, wait, don't. They don't like that.
They also don't like it when you say "I found this on the internet...."
