I hear it when I start the car for the first time of the day, as I'm in drive after backing out. It only seems to move from the center to the driver side behind the dash sounding like its gargling or sloshing. I don't hear it after a good 20 min drive. I am not sure what it could be. I've tried sudden braking but I cant replicate it. I will be taking it in to the dealer next week or so since it's under warranty. Just have a busy week schedule. :blink: Has anyone else had this problem, just behind the dash on the driver side?
