2004 TSX, something hanging down - What is this?
 

Hi:
The other day when exiting a parking lot, I heard a scraping noise when going down the shallow ramp to the street.
I looked under the car and I see something hanging down under where the engine is. It looks like a plastic panel of some kind. I can't get under the car but did take some pictures.
The red arrow points to what I see hanging down.
While it is hanging, it doesn't seem loose i.e. I can't really wiggle it with my hand.
Does anyone know what this is? I it something I need to take care of right away? Thanks...

Underbody dust shield. Bolts missing?

good luck

That's what it looks like to me. It will sag if any of the bolts/clips are missing.

I had the same issue on my MDX with the plastic clips missing causing the plastic cover near the radiator under the vehicle to sag. I purchased replacement clips on Amazon, $27,

Extra clips came in handy because about 1/4 of them were loose, broken, or missing between my three Acura and my daughter's Mazda 3 hatch. It also helped having a size larger because the OEM clips didn't fit securely because the hole wore slightly larger.

I had the exact same issue with my TSX. Seemed like it was some sort of metal that was scrape when i would drive.
Gripped it with my hand one day, twisted it and it came right off. Lol it was nothing important doe
