[CK09G6GT]

have 09 G6 GT 3.5. when it's cold out and u start the car for the first time and start driving it there's a rattling noise coming from the front end. seems to go away once it's completely warmed up. my girlfriends 08 G6 GT does the same thing. any ideas? and the gas mileage sucks!! thanks.

I don't know, but I hear the same thing. Like a very low muffled noise knocking noise. I had mine in last week and they say they replaced a loose steering shaft and it seemed to quiet it down, but tonight with it being so cold, I can definately still hear it. Super annoying!!! I'd like to figure it out too!!!
