2007 Malibu Muffler to body heat shield

I recently inherited a 2007 Malibu from my Dad, who passed away recently. The car has less than 11000 miles and has been sitting for a long time. He was 86 and hardly drove it.
I had to replace the brakes due to major rusting.
Recently developed a serious rattle when you engage the trans. I thought it might be serious. I finally had a chance to get a look underneath and it seems to be a very thin aluminum shield between the muffler and the body. It seems to be held in place by bolts with washers. It looks as if the washers have deteriorated. and the holes elongated to allow it to fall down on top of the muffler and rattle. I tried to remove the nut and put a bigger washer on it to hold it in place. The bolt turned right off and broke.
My question is has anyone run into this, and what can be done to repair it. I really don't think it serves much of a purpose being so thin. I thought of panel adhesive, and "gluing" it in place. The underside of the body is pristine as you would expect with 11000 miles.
Any help would be appreciated.
Should I just remove it and leave it off?

Looks as if nobody knows what I am talking about or they haven't run into this.
I went on the late model Malibu web site and had one reply with the same issue.

True, it is a heat shield for the floorboard, jute padding, and carpet as well as interior protection. Don't remove it in its entirety.
Don not glue it to the floorboard on the outside.

Find a way to remount the shield and leave a space between the shield and floor, as seen. Air is the best insulator.

Re: 2007 Malibu Muffler to body heat shield

I have it in the shop for a Safety certificate. I had then find a way to remount it in the stock location. I had a couple of bungee cords holding it in place until then. They actually worked really well. It will be fixed today. In talking with other people I have heard it is common in a lot of different vehicles.
