Yes.
I see from pictures you have a plastic bumper.
These are held in place mostly with plastic clips that are fastened inside the fender where you cannot see them.
You will need to put the car up in the air to see what to do next.
Volvo dealers sell the clips, as so do a few car parts stores.
Those plastic bumpers are very poorly secured, and fall off easily on all cars.
You may also find ripped or torn plastic holes which is why it is falling off.
If you wish to fix it yourself, you may need to do some really "creative" work underneath the car.
God bless your efforts.

Hi Van, Im AL the owner of Big As Auto Repair.

Van, you can fix this yourself. If you have a metal bumper and the piece hanging down is plastic, here what you can do. Go to Harbor Freight and buy a bottle of Guerrilla Glue, this stuff will fix anything. CAUTION: Do not get any on you hands because that's how strong it is. You'll need to hold it in place for a few minutes OR tape it up until it dries. Hope this helps and please visit my auto-repair-website: http://www.bigasautorepair.com/

This is probably just a splash guard that came loose under the car and hitting or dragging. Take a look under for something big and plastic that looks out of place around the wheel wells and under the bumper.

You must remove the entire front bumper and you will want to remove the radiator as well. There really isn't enough room there.

Remove headlights.
To remove the front bumper, there are plastic clips around wheel well and under the front bumper. Then there are a couple of bolts under the hood and two bolts on the side (look from wheel well up). The whole thing comes off as one piece.

I was able to move (twist) the A/C condensor out of the way and not drain it.

I wouldnt worry about it just sounds like the piece under the bumper that lets you kno wen u have pulled up too far on something e.x. curb, parking block

You should remove the bumper cover and take a look and make sure that the cover is not broken, its all plastic and the hold down arms sometimes break off and bumper will hang, also look for missing or loose fastners,

You have to remove the front bumper and grill etc

There are 5 bolts holding the headlight assembly in place. 2 at the top and 3 underneath.

Remove the plastic cross piece by prising out the clips and then the grille clips too then unbolt the bolts eithr side under the wheel arch. The bumper is still fastened using cips. Pull the bumper forward to unclip.

The plastic piece that starts by the bumper/fenders that runs along the bottom of the doors and side of the car Chrysler calls the Body Cladding (Left or right side), If you are refferring to the piece of plastic under the bumper and front of the engine compartment that protects the underneath of your engine compartment that is called the Belly Pan.

Well sometimes its the small things that count and on my grand am it took several mechanics to figure out the overheating problem. Under the bumper and between the grill/radiator are rubber flaps that hang down (to keep dirt from flying up from the road). Sometimes the plastic tabs don't hold them on or they rip from deteriating and hang down in front of your radiator. There was a small tiny piece of it hanging in front of my radiator causing it to overheat very badly. Took like 5 mechanics to notice this. No joke but i have replaced the seals and all but in the end it turned out being this problem. Very odd. You might wanna check into it. Look for anything that might be covering up the air circulation in front of the radiator and look very good because several people havnt noticed it. Wish i would have knew this before i started replacing gaskets and stuff.
