2007 Prius Hatch Latch REPAIR

The 2007 Toyota Prius has a manufacturing flaw - the rubbery covering on the hatch release button has a tendency to de-polymerize, creating a big gooey mess that prevents the latch button from operating. This disintegration has nothing to do with being in a warm climate, it's just Chemistry Gone Wrong.

A new part is $70, plus labor and overhead. You can repair this for $5, tops

In the first photo we have the BEFORE situation - a nasty, gooey mess. It's more than a cover - some of this glop extends down BESIDE the switch plunger, welding everything into a dysfunctional blob. (You'll see.) ADVANCE WARNING - wear disposable gloves when you are working near this gunk.

In the second photo we have the glorious AFTER. Functions smoothly, just like 2007 again! Ooo la, la!

BTW, there are two YouTube videos that touch on this topic. They are worth a look. First one is by [DIY]:

[Dufisthenics] describes -replacement- of the failed latch assembly. Alas, I fear he had too much coffee before making his video. ;)

Step 1: Detach Latch-and-Camera Assembly From Hatch

The first phase of assembly is to remove the entire latch-cover assembly. Click the individual photos for detailed comments.

First up, a word to the wise - DO NOT EVEN TRY TO REMOVE THOSE PHILLIPS-HEAD SCREWS YET! It's REALLY easy to remove them in a later step. You will experience Pain, Suffering, and Strippage if you attempt it now.

Step 2: De-Gunkify the Switch Mechanism

WEAR DISPOSABLE GLOVES! That de-poluymerized stuff is -very- sticky. Learn from my fail.

Step 3: Reassemble the Switch Assembly, Cover It With Rubber

See the notes on the individual photos for details.

Step 4: Final Assembly

Reassembly is pretty straightforward if you've gotten this far.

If you have closed the hatch while you were inside the house de-gunkifying the switch mechanism, then you will need trickery to get the hatch open again, That's right, to re-open the hatch you will need to crawl in through the side door and temporarily re-connect the electrical cable. :)

    I know it has been awhile since your original post. This project isn't for the faint of heart, though your directions are perfect. Dang that nasty black goop! I am glad it is off my car and that I can open my hatch without getting black tarry fingers.

    The actuator is a little less sensitive since I replaced the rubber and reinstalled everything. I'm wondering if I might have not have moved something a bit out of place in the actuator (the spring or that small metal tab)?

    Thanks for the steps to repairing this problem. It's something that Toyota should have owned up to, in my opinion. I'm still loving my Prius, though, and the 43+ miles per gallon.

    Nice tutorial! Nail polish remover is acetone, which is what I used. Worst part is digging out the old, rotten rubber. I used ShoeGoo as the sealant.

    Nice tutorial with great pictures !

    It took me 30 minutes to replace by a new one bought on Partsouq (about $50 including Fedex shipping).

    Thanks, great tutorial with nice pictures !

    I did it this morning after ordering a new part on partsouq.com. It took me about minutes, the most annoying moment is when the plastic clip were stuck on the roof so I had to remove them one by one.

    Nicely done! I love home-fixes for auto issues like this.

    Great first instructable too, by the way. I hope you share more stuff!

    Thanks! There are -SO- many things in the world that fail because of a design flaw of some sort. This one strikes -every- 2007 Prius. It's very rewarding to share a fix that makes them easy to use again. I smile now every time I open the hatch.
