I have a 2010 I4 SE Fusion. 26k on the clock. For some time now I have had a faint rattle/vibration noise under the car towards the rear. I have had it up in the air a couple times, and it appears that the long heat shield that runs through the tunnel and back towards the muffler is the culprit. There is a long section that doesn't have any attach points, and i can flick it and it sounds like a drum and is real similiar to the noise that I hear. It usually happens at about 40 miles an hour and under a partial load. Has anyone else had this noise on there 2010 fusion. I have stuck some pieces of rubber under it in a couple places and seems to muffle the noise some, but things move around, and the noise comes back. Before I start the warranty visits, i was curious if anyone else has similar noises.
