Just a heads up to everyone. I have a 2020 Rav4 Hybrid LE. The high voltage wires were replaced under warranty after 40,000kms and while they didn't say anything at the time it was due to the wires rusting out. It just happened again, two years later and I'm a FEW kms over the warranty and Toyota won't step up and fix the issue. $7,000 bill. There is clearly a design flaw with the wires under the car that get exposed to salt. The parts have been upgraded 5 times over 3 years so no idea if the problem will be solved but I wish I had known this as I would have bought the plain gas Rav. Just know, if you drive on roads that get salted you WILL have this issue and pray you are within warranty!!!!!!!

that looks pretty good. I think the unfortunate thing is most people find out about the issue too late (already corroded or a failure has happened) and the out of the rest some will be afraid to modify this and void their warranty relating to this issue. but I would consider doing this if everything looks clean under there. I'll be examining the area in the next couple of weeks.
eta: I just tried to go to their website and there was some stuff in french that I didn't google translate. can this only be purchased in canada?

Found this posted on Facebook, sad everything is in English on the FB page. Only this is all in French!
looks like a good product though. perhaps some of our canadian members will try it out.
Idea is interesting, but its cost of $350...
Also it's interesting - they shows different version on this video and installation video. On installation video they use sealant and cover has draining holes ..
Okay, I got in there on my 2023 today.
Some info here for those that haven't done this job. I'd say you want to jack the car up in some way. but be aware that the rear jack point is right next to two pop rivets (easily removed with flathead screwdriver if you are careful) and the jack might be in the way so if you can maybe remove these first. Here is the cover you need to remove. 3 pop rivets, 3 bolts (10mm, you'll need an extension).
This is the "up" side of the cover and you can see that it's pretty well covered in sand, rocks, etc. I hosed it off before reinstalling.

As you can see I have the "half open" design on the clamshell. There is a little bit of corrosion in there.

I sprayed it out with compressed air and then with the electronics cleaner. Looks slightly better.

Then I put the marine anticorrosion spray in there.
That brown color is the spray. I was very liberal with it.

So that's what I did. Will it help? I would think at least a little bit. I'm sure I could have removed the orange half cover and dived in a little deeper but I'm hoping this will be enough.

Which dealership was this?
They offered a replacement right away even though you weren't experiencing any symptoms?
I took my car in early this year for AM static issue and was told they would open a case with Toyota Canada... still waiting at the moment. dealership said Toyota was prioritizing cars that weren't driveable.

Echoing this, also received a letter from Toyota Corporate recently for the class action taking place by the fellow in QC and the warranty extension being offered.

Our 2019 Hybrid Rav4 just had this issue. Under 70K miles. It's been at the dealership for nearly 3 weeks and they can't find the part. Back order. They say it will be covered under TSB. Fingers crossed, but I'm not happy!

Has any companies started to make the harness kit yet as aftermarket?
Like Dorman?
Mine actually didn't look that bad I didn't think. There was nearly zero corrosion because it wasn't that old at the time.
No idea on aftermarket options. It's one of those things where here is a time where I'd maybe be worried about voiding warranty (not trying to get that started again!), should they extend one for my year. If it could be shown that a mod that I made made the issue worse that would suck. On the other hand will I just miss the warranty and have it fail because I did nothing earlier on? It's a tough call.

Our 2020 just finished fifth winter in eastern Canada rust belt. Dissembled after winter one and there was obvious signs of water ingress and corrosion at that time and failure was inevitable if left as is. Cleaned up, sprayed connector and reassembled. Just changed over winter tires and took the opportunity to inspect connector internals and found anti corrosion still doing it's job after four years with no sigh of corrosion, sealant washing off or any other degradation. Resprayed and reassembled connector. See no need to dissemble again due to condition of connector after four winters.
Only servicing other than routine maintenance for this vehicle has been recently with rear brakes wearing unevenly due to seized caliper pins. Serviced brakes and new pads all around. Usually have to replace rear rotors and pads after two winters around here. Pleasantly surprised!

Good stuff! I'll probably take a look at mine pretty soon.
What corrosion spray did you use? Thanks
Just finished spring inspection of cable. Cable treated with CRC 06026 Heavy Duty Corrosion Inhibitor, top of orange cower sealed with silicone gasket maker and actual connector filled with dielectric grease. So far looks good after 3 winters. I did not open connector this year - opened it last spring and discovered that dielectric grease hold well for 2 winters and prevented water reaching rubber gasket.
