Ran over piece of metal. Damaged plastic shrouding. Parts?

It sacrificed itself to do its job.

Take it to the dealer and I'm sure they can help you order the parts. Chances are you can do the work yourself, but you might need their help to find the part numbers using a diagram off TIS. Take the few bits you do have with you, there might be identification on them.

But I don't think anyone here has (as of yet) downloaded the whole set of repair manual to provide the part numbers easily.

I doubt the dealer will charge you to find part numbers unless you end up taking technician time by having them hoist the thing to look at it.

That would just be a base diagnostic charge too probably if you deem it necessary.

 

Oh man, that stinks! My son-in-law ran over something pretty big in his old Corolla but it hit the right-front tire so, now he's having a pulsing on his brakes. (I think he bent his rim or somehow the impact effected his rotor, which isn't even 9 months old.)

It's always annoying for me to find what-the-heck a part is called by Toyota! . "Board, RR1, No1" Really Toyota?

Hopefully these parts are accurate....put your VIN to verify.

For the clips, I have a few boxes of assorted ones I go through to put plastic stuff back on....they break and fall off so often some of the aftermarket ones seem more durable than OEM. Trying to get my Toyota parts department to get the right clip has not gone very well...they are wrong most of the time.

Looks like 58165-47050 for the under cover. Not sure about the HV cover/protector. Would need to see a better picture to be certain. I'll put the part diagrams at the end of the post and maybe you can figure out exactly which one it is.

Looks like the panel comes with almost all the clips you need to install it. It doesn't come with the screws, but you should be easily able to reuse your existing ones. It also needs two clips that aren't included. You'll probably be able to reuse your existing ones, but just in case, the part number is 90467-07220. They're only a buck twenty-eight each if you need them, so I'd go with the OEM ones instead of Amazon. The OEM ones tend to fit better and last longer.

Sorry, but those are the sheet metal floor pans, not the plastic under covers. (I have spent waaaay too much time looking at part diagrams. lol)
