Toyota’s stance on using a heavier weight oil

Hey guys, y'all remember when people actually thought Toyota engines would explode if you used a higher grade oil. Oh man, that was wild. Good times.
Their engines are disintegrating with recommended oils, so no need to introduce another drama.
In this drama, it was buried that their recall “due to the debris in the engine,” didn’t work, so they are recalling recalled engines.
Hybrid owners can still just pray.

Is there evidence that suggests oil is the culprit or is it a bad design/component? No oil can overcome a flaw.

Close to 250k engines under recall (including already recalled engines?)?
 
I have a new Base Tundra loaner with 10,600 miles on it that I just picked up. I believe it has the weakest 3.4 at 360hp/406ft-lb.

My initial reaction:

Powertrain:
-Lowest output engine is not impressive as far as power and acceleration.
-Engine IS very smooth
-Transmission seems well sorted

Driving/Ride:
-Windshield is weirdly tiny and cabin feels claustrophobic compared to last generation.
-Ride is superior to last generation in every way.
-Steering is better than last generation
-Brakes feel better than last generation
-Platform seems tighter and more rigid

Interior:
-I'll go easy on the interior since it's a base model with cloth seats and the extended cab.
-Cloth seats are not particularly comfortable - hard
-No interior rattles at this point

At this point, with the engine issues and the huge price increase, this truck is just not worth the price. If the engine was reliable and the price bump was modest, then it would've been a good deal.

Looks like I'll have this for 2-3 weeks. Hope the engine doesn't blow!

It won’t. Toyota is riding out warranty. After that you are on your own.
Simple.
That's an unconscionable plan on their part - they know they are defective. I assume the secondary market on these has already crashed? The hybrids will be worthless outside of warranty if they don't fix them.

I am thinking there will be a bunch of people who will buy them under the assumption that it is Toyota, and it lasts forever.
But yeah, they don't hold prices that good. 2nd generation is beating them, if you can find it. Sequoia 2nd generation is especially hard to find. I bought mine in 2024, and at one point, I realized I had to jump on it as I could see used prices rising because of 3rd-gen issues. Back then, some used 2023 Sequoia's were cheaper than 2nd gen.
 
If we're being charitable... it could be that Toyota does plan to do something about the hybrids once the non hybrids have been taken care of, however safety concerns would mean the non hybrid should have priority since the hybrid can still drive itself out of harms way if required when the main engine blows and they probably can't fix everything all at once.

That would be my guess. I do think Toyota will eventually get to the hybrids.

I think it's a main bearing design flaw, last I heard. Toyota bought time with the "machining debris in the engine" excuse but I'm hearing that many speculate it will need a complete redesign.

It was same thing in 2018 when first problems became evident in LS500. But Toyota thought they could scam customers and get away with it.
If there is any other explanation, I am all ears.

Simple.
Toyota has changed a lot. I see what you mean w/r/t your previous comments on Toyota reliability. I have a friend with two GR engines. Additionally his 4Runner transmission went out under warranty at 10k. He has a high pitched whine like a supercharger that is probably his timing components. And how he has a timing cover leak on his 2GR. But he's die hard Toyota still. (And he bought the extended warranty.)

There is a lot of perception there.
I mean I own Toyota, I owned Toyota’s before.
One thing they are really bad at is complexity. They should have just stick to simple engine design. GM is still pushing V8, Honda V6 etc.

This is what I've always assumed but they aren't being overly communicative about it. I understand why they aren't, they need to get the safety recalls done first and hybrid owners would flip out wanting replacement now, but that doesn't make hybrid owners feel any better until they do it don't do it.

There was a guy on Facebook and by 22k miles his Tundra has had the engine replaced 2x and the transmission 1x.

They put their engines/powertrains in so many vehicles and they keep them in service for soooo long you'd think they understand THEY HAVE TO GET THE POWERTRAIN RIGHT.

Or it's going to cost them billions...imagine this was the 2.5 hybrid/non-hybrid? That would be tens of billions. Extra testing. All your best engineers. Whatever it takes to get that part right and then use it for 10-15 years while Kia/Hyundai releases a new powertrain every 5 years with new issues.
