High Voltage Cable Big Corrosion Problem

Next time someone here gets service from the car care nut, ask for his “off the record” opinion of the Toyota’s half shell “fix” and if the new warranty extension is sufficient.
He has an actual on the record opinion of the fix in this video from 6 months ago. He talks about the issue and fix starting at about 9:15. He thinks it’s “kind of ridiculous”. I’m willing to bet that gen 6 will have a non-ridiculous fix: connector moved to the spare well.
 
In reading his comments in the comments section all he says is that it's fixed and as far as I know he hasn't said anything else. He has said that he pays for Toyota training.
Right, he says it’s fixed in the comments. In the video he says the fix is kind of ridiculous. I agree with his opinion. It is kind of a ridiculous fix.
 
I really like car care nut’s content and I appreciate his occasional candid criticism of Toyota engineers in his videos. Hence the “known issues” portions of his videos. It shows he’s pretty objective and not just an obsequious fanboy of the brand.

I think he has a “we will see if it helps” attitude toward Toyota’s fix on the cable. But, one can infer by his head scratch / eye roll in the video that he’s not optimistic. Neither am I.

I own a mid ‘22 build J RAV4 hybrid. I haven’t yet crawled under to see if mine has the “fixed” connector boot. I am concerned that if it does indeed have the new boot, I will not be receiving the coveted warranty extension letter from Toyota. It is obvious to me that Toyota is trying to kick the can and limit any civil liability with this sawed in half boot fix. They will be able to make the claim their engineers have identified and solved the problem. The 1/2 boot will only slow down the inevitable failure of that connector, because the real problem is its location, orientation, and metallurgy. Toyota has to know this. They also know that by the time a “fixed” connector fails, RAV4 will be long into gen6 with the connector safely tucked above the motor somewhere in the cabin or spare well. And by that point, warranties, extended or otherwise, will be expired.
 
I’ll bet Toyota has had it with road salt at this point… it cost them 3 billion with the Tacoma.

I did a cursory search to see if Toyota refused to repair any rotted Taco frames that had owner applied rust preventative. Couldn’t find any. You can infer either treated frames didn’t rot or Toyota didn’t care if they were treated.
 
Nobody should ever feel compelled to do anything they don’t feel comfortable doing, no matter what it is.

Me? I feel totally comfortable spraying a corrosion prone metal part with a hydrophobic lubricant film designed to prevent corrosion. I’m adding a spritz of acf50 to my every 5k list. Might take all of 30 seconds after the oil and tire rotation. If the cable still fails and the dealership tech decides to send the connector to the Toyota CSI lab to test for anti corrosion films… well, I’ll cross that bridge if it ever happens.
 
Curious if anyone here with a J-VIN has received the letter? My ‘22 RAV is Japan built, and no letter yet. Starting to to think this warranty extension may only be for NA made. Time will tell, but that would explain why the Prime and Venza aren’t being included. 🤔
 
My concern is Toyota’s use of “certain” in the CSP 22TE09 document:

“CERTAIN 2019 –2022 MODEL YEAR RAV4 HYBRID AWD”


First diagnostic step is a VIN search to determine if you are covered. It is not ALL 2019-2022.

I have yet to receive notification by mail that my warranty has been extended. I’m due for my first scheduled maintenance at the dealership soon. My first request of the service manager will be a CSP search on my VIN. The result will determine how long I own this particular RAV.
 


Cool, thanks for posting. I believe those search engines are only for recalls and general service campaigns. I don’t think we’ll find the cable warranty extension info there. I’m thinking that info needs to come directly from Toyota, or a Toyota service center may be able to run a VIN search. I’m now so curious I will call my dealer on Monday to find out. I’ll report back.
 
I called my dealer service department to find out if my VIN is included in the warranty extension. I received a verbal confirmation that it is included, BUT with a big caveat from the service manager that I need to wait for the letter from Toyota for official confirmation. Not sure why, I guess the letter is magical. Or, the service manager wanted me off the phone.

So, somewhat encouraging news, but I wait.
 
Back to the letter, there are pictures in the notification that show what may appear in Multi-Information Display and/or in the Head Unit Display. However the littlel pictures are too small to see what they are trying to say. Can anyone help?
Yeah, the pictures in the letter are pretty blurry. I think the MID message says “hybrid system malfunction call dealer”. The infotainment screen message looks like “hybrid system- a malfunction in the hybrid system has been detected. Contact your Toyota dealer in order to have your vehicle inspected”.
