What is the name of the hard plastic flap underneath front of car?

I think it's a splash shield but don't take my word for it when you go looking on any of the micro fish computer breakdowns online you will clearly see this piece It's not rocket science it doesn't take any special skill or any of that and then you look at the corresponding number and it'll give you the name and the long part number and whatever else to sight gives for parts like this you're probably going to want to be looking on amyama some of the aftermarket body shop suppliers may carry some of this a lot of people just leave it off

 

Welcome to PriusChat!!

You can buy aftermarket metal versions (pricey), or less expensive (flimsy plastic) aftermarket options (when compared to OEM), but given your location (salt much?), best to replace it with anything that helps prevent potential salt damage to other areas of the engine or vehicle. It appears that you may benefit from a "lift kit".

The plastic that is used for that is a styrene based type of plastic if you burn it it burns black You want to try and get something that's made more of PVC It's flexible it will bend rather than bend and break or snap same with the wheel well liners especially the generation 3 you notice how they break if you smack them appropriately or whatever they break I bought some fender liners from a manufacturer and they're more like PVC that will bend and bend back so when they get crunched in an accident a little bit if you just pull the fender out the liner comes right with it still attached to the metal and attached to the inner mount points so you just pull the fender until the liner looks straight and the whole thing is pretty much straight whereas the factory fender liner would have been broken all the hell literally been in pieces laying on the ground sure I'd like to get a metal one aluminum one whatever they are but yeah I imagine they're $300 a pop where is the thing we're talking about here is maybe 60 48. And my vehicle in reality probably off-roads as much as any of you with a lifted Prius camping in it and what have you I'm out on trails very regularly on people's property going down to streams lakes ponds that are filtered swimming pools things like that almost on a daily basis My car is in 2 3 ft of high growth nine times a week nope it's not my property so on customers property.

 

Well the question mark at the end means you’re not sure of your inability?

to find out what it is, look up parts online. It’s currently quite challenging to use Toyota USA’s official parts site; it had some recent “improvements”. Trying individual dealership parts sites may be better, or they may be tapping into Toyotas (messed up) site, not sure.

Try also Amayama. Finding the parts there, then searching for those part nos on US SITE might be most expedient, or just order through Amayama. The latter is often cheaper, even all-in with shipping.

don’t neglect fasteners either.

if it’s overwhelming, contact local dealership parts department, maybe drive over; the car will be a great “visual aid” as to what’s needed.

bottom line, if you want to DIY fix this, it takes some research, and the ability to raise the car slightly (ramps would work).

 

I think I put mine back on with twisty ties (or metal zip ties from harbor freight) and possibly screwing some new holes to make it easier to reattach. Good luck!
