Normally, I have my radio at a fairly loud level. For some reason, I didn't have it on and noticed a rattle type of noise coming from the front. It's speed sensitive, starting about 58mph and gong away below that. RPM does not affect the noise. I'm thinking its the grill shutters rattling. This also brings up the question why are t hey even there and what function do they perform other than possibly speeding up warmups?
