Rear shelf rattle

[aspec818]

There’s a consistent knock somewhere in the back of my car and I think it may be the shelf. I didn’t really see an apparent way to quiet this. Seems like the adhesive in the shelf is failing.

Aha! Maybe THATS my issue....haven’t had time to diagnose yet. Thinking it’s my foot sensor for my Auto Trunk that the 3M adhesive may have given way due to the fact that I didn’t want to drill the undertray to attach. What’s weird is I get this odd rattle even when I’m not going over any bumps or road imperfections. Initially thought it was a rear fender liner slapping or blowing, but they all seem secure.
