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!!!!!!!

Gm learned that open face wires still corrode, but it takes about twice the time to corrode and fail so it gets them out of the current recall as cheaply as possible it's not a genuine fix unfortunately as a mechanic I can say the gm had open face ground wires on the starters for many many years and every gm starter fails on average about 5-6 years and the original cablegate was a average 3 years before failure

I belive its mostly the hybrid and ev designs and possibly the prime, I personally got a special ordered rav4, with front wheel drive only. However if memory serves me correctly, the cablegate issue affects a connection at the rear wheel electric motors. so if the rav4 your interested in purchasing has electric motors at the rear wheels. It will likely have the cablegate issues ,or remnants of that prior issue before recall. As a heads up open face wires take twice as long to corrode and rot out. I can't count how many starter motors on gm products with open face ground wires failing on average its about 5-6 years before the failure and a starter motor averages between 160-280 aftermarket and somewhere in the 350-500 for dealer replacement for those whom like original parts, hope this helps you find the perfect car of your liking personally just get the rav4 xle gas model its averaging 30mpg highway and 25-26 in city, the rav4 front wheel drive only I got gets about 34 highway mpg and 29 city but also has about 1,600lbs less of weight without the all-wheel drive powertrain

ummm, what ?
which rav4 uses a kevlar belt CVT ?
seriously, do you mean old UK/Australia/Taiwan versions from 2013 ?
-----------------------------------------
todays rav4 has either a normal automatic 8 speed tranny
or
it has a hybrid synergy drive known as e-cvt and there
are no belts. it is all gears meshed into gears and a planetary
gear system controlled by mg1 which starts engine, controls
engine brake mode (downshift simulator, or prius B mode)
and also controls how much engine torque goes to front wheels
mg2 also runs front wheels
mgr runs the rear wheels in forward, and provides reverse
In the US, the non-hybrid 5th generation RAV4 has a conventional 8 speed automatic transmission, not a CVT.
The only conventional CVT rav4 has is the K120 transmission, with these models using it
no one worried about hybrid wire corrosion (this thread) has one of those K120 transmissions
(unless they also have an XA50)
we all have directly meshed metal gears and planetary gearset. no slipping belts, no kevlar belts, none of that
K120 "Direct Shift" transmission (2018)
Toyota brands the K120 as the “Direct Shift” CVT and includes a physical first gear (also known as a "launch gear") and nine additional simulated gears, for a total of 10. The launch gear is engaged when the vehicle takes off from being stopped and transitions to the belt drive as the vehicle picks up speed. The benefit of this system is that traditional CVTs tend to have low efficiency in lower gear ratios, creating a moment of sluggishness when starting from a stop.[2] Since the belts in this CVT are handling a narrower band of ratios, belt angles and loads can be reduced, increasing shift speeds and offering a claimed 6% improvement in fuel efficiency.[3] Production began in October 2018.
Applications:
the CVT pushbelt for the K120 sure looks like an ordinary metal CVT belt, not kevlar
![Image]()
this>>"Rav4 uses a cvt transmission too just the belt is a braided Kevlar material so it's supposed to have twice the life expectancy of a normal cvt transmission, also Toyota builds these cvt transmissions significantly better internally over their competitors "
-------------------------
I am gonna say no. the reason the CVT last longer in the K120 is the normal first gear (launch gear), that takes a lot of load and heat off the CVT
so that the CVT belt is only in use when already moving, greatly increasing lifetime and reducing heat and wear from standing starts.

Was the 2.0 available anywhere but Japan and China?

Toyota sells RAV4 with 2.0 and CVT in Europe.

Ah, for some reason I thought Europe only got HV. Must be thinking of UK…
The Wildlander is the Chinese version of the RAV4, not sold in the US. 2020 Toyota Wildlander Is China's RAV4 With Half A Lexus Spindle Grille | Carscoops

Of course, but the RAV4 mentioned before the slash refers to the 2.0 liter RAV4 with traditional CVT, sold in Japan and Europe
it’s a worldwide vehicle and this is a worldwide forum, after all!

Not much of an update just yet, but wanted to come back read this thread.
I spoke with Toyota Canada after finally getting through after the holidays, they have lots of concerned customers trying to contact them I guess.
The lady I spoke with acted very unknowledgeable. She basically told me that they had no information on what each customer should or could do, to prevent this expensive wiring harness corrosion repair from happening. She offered no updated repairs or modifications from Toyota. She kept saying that I need to contact my DEALER to get any updated information and any preventative measures done by them, or the customer.
She said that they would have been advised by Toyota on what to do. I calmly asked her
to direct me to the "people" who are advising the dealerships with this new information. She didn't know how to do that. Sounded like I wasn't speaking with the proper level of technical support, even though I asked for it. I did however tell her that some dealerships aren't honest about situations like this and they pretend not to be informed. Can't wait to have that discussion.
I do have a brother in law who works there as a tech so I will get the real story soon. He's been away on vacation for a while now.
To be continued....

Another update, sort of.
Spoke with the dealership today. They said that there was an updated connector cover which is now open on the bottom at least, so water couldn't stay in there. They said that the 2019, 2020 and 2021 hybrids were the most affected and the newer models were not a problem anymore. He also told me that the extended warranty was only for the "trouble vehicle years" so that means the newer models like my 2023, still only have the 3 year/60 thousand warranty.
This clown was really not interested in this conversation at all. He even smirked when I said this was an expensive 5-6 thousand dollar repair if I had this issue once the short warranty period was over.
I think I'll crawl underneath my Rav4 in the next few weeks and take a look at this "FIX".

The extended warranty goes through the 2022 model year. (See customer support program 22TE09).
My '21 RAV4 hybrid came from the factory with the "new" open cover, but is still included in the Customer Support Program, so obviously the open cover does not solve the problem.
I received my Customer Support Program notification letter on June14, 2023.
See these documents for more information:
T-TB-0026-22
T-TT-0630-20
T-TT-0690-22
Yeah, that's the case since 2021 models... And it has little effect.
Note that the person you responded to appears to be located in Canada. So even though Toyota has announced that the warranty will be extended the same as in the US (such as reported by the APA), we still have to receive any official notification (at least I haven't).
Me neither.

Same here. 3/22 build. Has the open cover. Received the Extended Coverage letter for my VIN.
I read somewhere that Toyota changed the cord plug, or at least changed the seal inside of it sometime in late'22. I hope if that's correct, that the extra seal stops corrosion from getting in the plug. If not, us '23 & '24 owners may be ,shall we say, short on luck...
