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...
2004 TSX

 

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
