The problem with the engine manufacturing process where shavings were not cleared from some engines, is endemic to the 2022 and the very very earliest 2023 model year LX600s. NOT 2023 and 2024 models.
Please please please don’t perpetuate incorrect information on this.
I’ve posted on this time and time again to try to set the record straight, per the official Lexus and NHTSA documents. Please see this post for the correct information, all in one place.

Its not new they have had it out almost 10 years in the LS.
If you are worried change to a higher viscosity oil. A good 5-30 GF6A or 0-30 Mobile 1 ESP (also called European car blend, and is the one you want). Mine runs exceptionally better and I am going 0-40 next change.

I have a 2024 LX F Sport and have the same issue with the cruise control usually settling 1 mph below the set speed. I don't have any of the other issues. Like you, I'm changing my oil every 5k miles and did an initial change at 1k. They question it when I bring in it but once I explain what I want to do they are cool with it.

Per The Car Care Nut as related to the Tundra, it appears they changed a bearing and I think another component as part numbers changed.
Not sure if this the same with the LX as these are made in Japan. Per The Car Guy online, he has documented failures in the Tundra platform well into 2024 and one 2025 thus far.
Hopefully the Japan made V6 is not having problems.

He makes it sound like its a Yugo, “when they are running”.
Outside of the first gear downshift delay and confusion, my LX is pretty good right now with the heavier oil in it.
Add in the jack rattling and credit card key intermittently (usually) not working for the lock/walk away rear hatch function. That stuff isn’t overly bothersome but I am surprised there isn’t a fix 4 model years in.
Its really wild to me that Toyota/Lexus hasn’t addressed these issues or put out a TSB about the jittery/vibration and oil weight.
It was completely wild the change from 0w-20 to 5w-30. Whats crazier is that some people say theirs run fine with 0w-20 but mine vibrated enough where I wouldn’t want a pregnant woman to ride in it (especially geriatric).

I think all the harsh criticism comes from the parts # change in early 2024 on some lower end motor parts. Makes Toyota look disingenuous.
I am kinda on the fence about the ‘machining debris’. Definitely think the water thin oil complexes the issue.

BUT the 700 doesn’t have these issues, that is the main issue with these in my opinion; the tuning,its really bad on the 600.
I also wouldn’t drive off the lot without making them change the oil to 5w-30.
I have done the oil and I bought tunes. I wont do the tunes till next oil change when I put a higher viscosity oil in. That should fix the transmission and throttle tuning I believe.

Anyway, when I got my first oil change in July this year the advisor said that they needed to stick to the manual with 0w20. Last week though, they had no problems changing to 5w30.

To your [snarky] point, Lexus merely expanded the recall in recent weeks beyond the initial scope of 2022 and very early 2023 trucks, to newer models, for the same "debris in the engine" reason, which is incorrect. This, after implementing a so-called "fix" that didn't work and supposedly revising their manufacturing processes in the early 2023 time frame. Was I supposed to read Lexus' minds back in May 2025, a full six months ahead of their expanded recall? You tell me.
The problem is actually a flawed engine design, particularly with the "ladder frame" casting that bolts to the bottom of the block and contains the main bearings, which tends to show up under load.

The only thing Toyota has officially said for the later MY engines is from the current recall, when they said that engines made with improved manufacturing processes (unconfirmed when they were implemented, implied to be earlier than April 2024) had lower amounts of debris (but still didn't say whether that made the engines perform correctly), but they were still monitoring the problem.

It’s clear you are loaded for bear and want to argue about this. I’m happy to let it play out and we’ll see down the road if Toyota come clean and releases more information about the cause for the engine failures.
Remember, though, that Tundra engines are produced in the US, and LX engines are produced in Japan. That doesn’t automatically equate to the processes used to manufacture them being identical. It could, or it could not.
Anything more you want to accuse me of doing, saying or being, tough guy?

Honestly it's no big deal - Toyota is deliberately slippery in these reports, but go tell yourself whatever makes you feel better, buddy. I'm sure you're very smart and you've always been right your whole life and have never made a mistake.
