Ok so I read the report twice here is my reading:
1. The problem really is debris created during the manufacturing process. If the debris is of a certain size and happens to lodge in the #1 main bearing it will fail.
2. They implemented process improvements at Alabama and continue to, at Tahara they made them after initial recall.
3. They also created a more robust #1 main bearing and that went in engines made in both plants.
4. They are very specific that between the first set of process improvements and the time when they made the part change is where the problem was/is.

My reading:
1. I would buy a tundra. New part that seems to help and lots of process improvement.
"These analyses showed that the subsequent

period, after additional manufacturing process improvements were introduced, had lower counts

of debris of these larger sizes."

2. I feel a lot better about a new LX. There is of course a non zero chance you could get a bad one but new part and process improvements are big. It also seems like they were much more worried about Alabama as they did daily swab tests on those engines but didn't feel it necessary to do it in Tahara.
Most important for new buyers of LX owners:
"
For the Tahara plant, data from the recovered engines,

study about the bearing robustness, and the field performance data indicate that an increased

level of this type of debris is present in engines produced between recall 24V-381 and the

implementation of the improvement to the #1 main bearing."

Thanks for compiling this @snowman69. I read it the same way but did not have the patience to educate others here as you have cordially done. It is super clear that the odds of 2025 LXs (all engines built in Tahara) will face the same issue of the early ones subject to the recall are close to zero now. Not zero though.

Tundra engines made in Alabama might be a different story, but so far there is this ONE guy that had the bad luck of purchasing a lemon, (rightfully so) yelling in the Tundra forum. That's the extent of the evidence against 2025 Tundras presented here.

It is interesting to see no note about hybrids or non-hybrids. Should we read this to say irrespective of that ALL Tundras produced during the recall window should be covered?

What? Taking the document at face value the 2025 Tahara models are most definitely resolved.

Right. The document that he himself posted.

It looks like my build date was 11/23. I was worried about hitting the 50K mile mark next month and warranty coverage. Now it looks like that problem may have been solved. It will be interesting to see if they have any issues with the fact that I had them use 5w30 at my 40K oil change.

I am ok with being in the recall because I can run the higher viscosity oil and do other misc without worrying.
 
Have the TTV6's in the GX550's had any of these problems?

Only 3717 of the 30,000 or so they've sold in the US are flagged for recall.

I can’t believe they went all-in on the V35A without it being bulletproof. I’m confident in their design and testing, so maybe it is something in manufacturing. However, rumors of part number changes suggest differently.

Just mind blowing that they stuck this engine in Tundras, LX600, GX550, LC300s. Those are the vehicles that evoke a sense or reliability and they are doing some serious damage to that reputation.

They don't have to be the best. They just have to be slightly better than the next best thing, and when that's GM, Ford and stellantis (or in our case, JLR I guess? No real LX competitors) it's not a high bar to reach.

All that says is that in 2023 and early 2024 they saw increased debris from the Tahara plant - nothing about improvements afterwards. It probably got better, because that's what happened at Alabama after they implemented the changes - but I'm not sure why they weren't willing to collect data on that and explicitly state it in the report. Maybe Tahara has smaller failure rates to start with so data uncertainty would be too large? You'd think they would want to protect the reputation of their top end brand first...

This part is also strange:

"because the Alabama plant continued to implement additional manufacturing process improvements to reduce the potential for debris during this time. Toyota also reviewed the manufacturing contamination improvements at the Tahara plant after the period covered by recall 24V-381 and confirmed that the production process was generally unchanged for this period."
Click to expand...

So Alabama kept on improving the process between 2023 and 2024 but Tahara didn't? I guess it didn't help anyway because they found increased debris in both plants during this time.

This part is somewhat worrying:

"This initial comparison did not identify a correlation between production contamination variability and the engine failures seen in the market."

This suggests the problem might go deeper than just debris...or just a poorly worded sentence.

To put this issue to rest, Toyota needs to issue 2 statements:
1. Deceased debris at the Tahara plant after manufacturing changes were implemented in early 2024
2. Correlation of lower engine failure rates with deceased amount of debris.

As of right now, all they are willing to say is that the engines produced after the recall period are "under investigation".

"Some of the same engines produced after this period were produced with improved manufacturing processes and remain under investigation."

I wonder how they are doing in Japan? Is there an equivalent to the NHTSA safety recall there and what are their standards?

very few other manufacturers would give a no questions asked engine replacement such as this, yes other models/years should be included and i think they will, i believe (conjecture) that they are spreading out the engine replacements into a longer timeline to be able to meet demand of the recall, there seem to be some discrpancy to what ive heard on mileage/years for accepted engine replacements but the least ive heard was 150000mi or ten years, so at 140k im going in for my new engine, no worries, accept having some dumbass noob install the new engine.... but that will be on them too.

Very excited about their new twin turbo v8, even with this smudge on the engineering, but they are going good on this and actually trying to remedy this so I'm still 100% on board with toyota, i think it shows integrity how its being handled
 
Is there a site anyone uses here to check actual build date of a car based on vin besides checking door jamb?

The original recall for the United States, 24TA07, also saw recalls issued in the EU (Portugal) and in the Middle East (Qatar). I'm going to assume that we will see more of these from around the world in the coming weeks.

This is exactly why I held off. We spent months looking for a white on peppercorn luxury trim 2024 for my wife. Finally found one in March but got cold feet and wasn't convinced they figured this out yet.

Got a quad motor R1S , it's great but it's no LX in terms of build quality and materials. Still hoping they figure this out in the next year or two. Or just give us a V8 again.

tt 4.0 v8 is in the works....slowly.... be years before we see it in anything but their racecar,
the ttv6 is a good engine (sans machining debris)
so doesnt matter what it is if it has faulking machining debris in it though

But is it really machining debris? :)

The rumored part redesign change in Q2 of 2026 will tell us the truth.
 
they put a new bearing in it to try and resist degradation from the combination of
(A)-machining debris,
(B) a high torque engine being harder on bearings,
(C)the low viscosity oil speced for mileage reasons
(D) fact that during the first break-in period turbo engines tend to dilute the oil with fuel more due to the higher pressures in the cylinder and more loosely gapped rings further washing out your oil's viscosity, and
(E) the 10k mile or longer speced oil change regiment with no break-in oil changes
i suspect if a few of these variables were changed this would never have happened, ie no damn machining debris 😅

its never one thing that leads to catastrophic failures, there is always a constellation of factors,
there was a mildly alarming amount of debris in my oil when i did my first oil change at 500 or so km
