Looks like it includes the LX600 as well according to the Toyota press release… in addition to the transmission recall from a couple months ago

A big problem that I see is that the issue is still happening to 2024 models after the end of the recall notice. The metal shavings issue was found out more than a year ago, and they supposedly already fixed it. So why does this notice extend out past the initial discovery in early 2023?

I don’t think it’s a debris issue, it’s a fundamental design of the motor issue. Wether that being lack of lubrication due to the oiling system, or bad design within the bearings being on a cradle system rather than being able to be independently torqued down.

Remedy: Toyota is currently developing a remedy for this issue.

What does that mean? How do you remedy 100k engines with a 1% chance of metal pieces?

It doesn't...it is for Nov 2021 through Mid-Feb 2023...how is that extending past "early 2023"...?

And if it were a fundamental design issue, there would be more failures...

And just so everyone here is clear, I have a brand new V35A-FTS (Type '21) short block sitting next to me...

Well now we need more short block photos!

Oh I missed that detail - thanks for catching that.

So why are 2024 trucks still being affected?

Seems like a distraction to me as they have not remedied the issue, and blaming it on machining debris sounds like a BS excuse to me.

Hope the fix is to simply drop in the 5.7 as a replacement motor instead of this botched design.

Are LX600 engines made in Japan? I know the Tundra engines are made in the US. So they have the same machining debris issue in both plants?

Yes, the LX600 and LC300 motors are built in Japan, which just doesn’t pass the smell test to me. Both of which are having problems.

This is a design issue…

The snowball continues to grow. Stay tuned

Or a process issue...

Just looking at this picture reinforces the fact that they can’t independently torque down each main bearing cap because it’s a cradle system and each one acts on another.

If that cradle is even off by a hair thin margin, it will blow the motor.

Toyota messed up big time on this one.

And yet...there are plenty of Tundra over the 125,000 mile mark...so...we won't ever know the full story...

I'm just glad I only paid $480+$200 in gas to Kansas City and back for it...

Maybe the strategy on this set of vehicles is to buy them in the 100k mark after they have gotten past the initial break in and things are loosened up. (And checking that the initial motor was never replaced)

That way, you know the cradle was machined correctly haha.

I'm at 47K on my Feb 2022 and she runs like a top...premium fuel and 5K OCIs...3 oil changes before she hit 5K...

You do know that this is a very old engine design-- ladder frame bearing cap that is machined in conjunction with the block. Toyota diesels have been this way since at least 1990. One of Toyota's greatest diesel engines-- 1HD-FTE -- is designed this way. Almost all new engines are designed this way as well.

I'm going with a process issue not a design issue.

 

[rexington14]

Sounds like it was a procedural issue - which would be in effect at both locations due to standardization of manufacturing processes under TNGA. The fix was probably something like "run it through the parts washer again"

So, based on affected production dates listed in the notices (ending: Feb 2023 for Tundra, LX is a bit more vague - 2023 models) we can reasonably assume this particular issue has now been addressed. And, as a result, never was a problem on the GX550 to begin with.

So, good news, everyone who was on the fence on a new GX just because of this issue, you may now head on over to the dealership.

Sport motorcycle engines have been using a similar design - 2 cast parts (upper and lower crank cases) bolted together, with the crank bearings machined between them, for decades. Even little Italian mfgs that aren't known for reliability, and only produce a few engines per month, manage to not have any problems with the configuration of the crankshaft and bearings.

FYI
My late 11.2023
2024 LC300 has had the transmission recall done in the last service.
The 10 speed Transmission is okay but I still feel the 10 speed isn't as smooth as the 6 speed I had in my 1gr 300.

Glad to see the 2024 isn't included in this engine recall but would not be surprised to see if that changes in a few months...
