Hit a broken tire on highway

I whacked one of those with my Gen III and ended up getting the whole front end piece replaced. They said whatever method I might try to fix it, JB Weld, etc., it would end up cracked again.

 

You could probably weld that back together with a hot plastic welder. They're cheap on Amazon and it isn't exactly a precision skill, for a bumper anyway.

Or drill a couple of holes on either side of the tear and bind the halves with black zipties. You want the black ones so sunlight doesn't break them down in a few months.

99% of the battle is the prep you put into it before actually applying an adhesive.
The majority of failures are due to improper preparation and lack of proper support while curing.
A small piece of flat lumber and a jack would probably work wonders for keeping it aligned and pressed together while curing. Regardless of how fast it says, I'd let it sit undisturbed at least overnight.

 

Is it just me, or is there more stuff hanging down, further back?

 

Yeah, looks like the undercover is hanging down in the rear.

Yep, JB plastic wield and drill a couple of holes to zip tie that crack together. You probably sheared a few of those plastic pop rivets on that rear under body cover too. Those will also need to be replaced, otherwise they will slap around down there and eventually tear-off.

Hope this helps....

 

^That.

Judging from the photo this isn't the first time you've had Foreign Object Damage or what we squids call FOD, and this is a 2016 car that we're talking about, so looks aren't the number one log on your pile - am I right??

Do the J-B Weld thing - CORRECTLY, and get on with your life.
NOBODY else is getting this close to your bumper ANYWAY, unless they're up to no good.

 

Yeah you’ve got to raise it to properly deal with it. Google search for:

One of the top results should be direct to the pdf on PriusChat, has all the info for fasteners.

 

For the painted front fairing, if you remove it, clean up the crack with alcohol, tack it together with with super glue, then apply 2-part epoxy glue, reinforced with fiberglass mesh on the backside, you can get a fairly seamless repair. Get a spray can of your color code, and just go over it lightly. It's down real low, hardly noticeable.

 

Plastic zip ties might not be a good idea. I zip tied rubber pads to my roof bars last summer for my kayaks, and by fall they were brittle and broken. Same with the ties i used for my Prius plastic underbelly. All brittle and broken in less than a year.

 

Lowes has some of the more common type of auto part fasteners when looking for a source.

Guessing these were the whitish cable ties. Those are for interior use. Need to use the black ones for outside like @Leadfoot J. McCoalroller said; those have UV protection. The other colors may or may not survive in the sun.

 

That aforementioned TSB attached now.

The Toyota fasteners for the engine underpanel were reasonably priced through Amayama, even with shipping cheaper than local dealership: If you bundle with other items the shipping doesn't change much either:



One advantage, you know they're going to fit. Also, in oil change link in my signature, there's some tips on preserving those fasteners. I've purchased a complete replacement set for the engine underpanel, and so far have only replaced 4~5, typically due to a broken tooth.
