Got me to examine mine and here's what I found. Most of this material has a sticky backing. Near the front of the driveshaft, I had a piece already sagging, so I just pressed on material and it stuck back on pretty good.

Then I examined other places and noticed a couple of missing thingies that holds it in place. Not too worried because the whole thing feels like it's stuck on pretty good.

If you are concerned, I would just crawl underneath and make sure everything is tidy. I ended up pressing on everything while I was down there to make sure it stuck on well. If I get the recall notice I will mention the missing holders but I think most of our Tremors are in the clear. Here's the last angle showing clearance from driveshaft.
