Heat shield rattling under car.

[BIRDVERT92]

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.

I have a 2006 SE with 93,800 miles...my heat shield began to rattle about 20,000 miles ago, but the dealer agrees it is the culprit, and has not recommended any resolution....

Haven't had it on my Fusion, but my wife's 99 Escort had 2 or 3 that rattled pretty bad once one of the mounting points had rusted through. I cut them off with an angle grinder 3-4 years back and it's been nice & quiet since.
