On our first long trip in our new-to-us 2017 Prius (Three), I notices a "fluttering" or buzzing sound above about 60 mph that varied a bit with speed and the bouncing of the car over waves in the road. It appeared to be coming from around the driver's door. Stopping to check it out and finding nothing at first, I finally traced it to a loose panel under the car - between the left front wheel and the "bumper" (front air dam). I was able to snap it back into place and all was well - until about halfway through our second long trip, where I heard a scraping sound getting off the interstate. Sounded something like a brake disk shield. Turns out this same panel - a roughly triangular piece of plastic maybe 10" or so on a side - had come loose again and was now scraping on the ground. Being a little smaller now (due to being dragged against the pavement for perhaps 100 miles) it didn't snap back onto place. I was able to tie it back into position with a zip tie. At any rate, I'd like to replace this piece and do a proper repair - and fill in the whole area again - but from what I could find online - it looks like this piece is only sold with a whole fender liner/splash guard/wheel well/ whateveryoucall it. I found it online for ~$72 buck (plus shipping of who knows what) but I was wondering if anybody else knew if the part I'm looking for is available by itself. Near as I can tell, this is the whole part: 2017 Toyota Prius Prime Fender Splash Shield (Left, Front). Interior, HOOD, Body, Radiator - 5387647140 | Serra Toyota, Decatur AL The piece is relatively flat, I could could likely fabricate one, but it would be nice to have the "right" piece there. I'll have to get the car up on ramps to inspect further as It looks like other similar parts under the front of the car have similar damage. I would guess that the very-low front end has had a few encounters with curbs, or dips in the road from the scuffs on the bottom of the front air dam - and that broke something loose to start the process of this piece coming off and getting further damaged.
