dont know about any humming. mine is a 1g though. cant remember if yours is or not. anyways. maybe it has loud tires on it. my tires were loud on an older car i had and after i changed them out it was quiet again. you might take it in and have them look at it though. there is nothing wrong with preventative maintenance.
