2024 GX Engine Recall?
- Thread starter cartermatthews
- Start date
Then explain why the expanded recall only applies to the Tundra and not the GX 550, LX 600, or LC300 if 2025 versions of those models are supposedly going to be affected too?
One thing the GX 550, LX 600, and LC300 all have in common is that they are global export models sold worldwide, not just in the US like the Tundra. If Toyota genuinely believed all 2025 V35A powered vehicles were still affected by the same issue, we would likely be seeing a much broader global recall by now instead of one specifically targeting certain Tundra production ranges.
And another important difference, the GX 550, LX 600, and LC300 engines are built in the Tahara plant in Japan, while the Tundra’s V35A is built in Alabama. Different production environments, different assembly lines, and potentially different manufacturing variables.
Toyota already identified the earlier contamination issue and implemented revised manufacturing and mitigation measures afterward. Even the latest recall documentation only points toward specific Tundra batches, not every vehicle using the V35A engine.
Quoting magazine articles about earlier contamination issues does not automatically prove every 2025 GX, LX, or LC300 is destined for recall.

Saying “updated #1 bearings are failing” without showing actual production data, failure rates, or an official expanded recall for GX 550/LX 600/LC300 doesn’t automatically make you right either.
No engine platform on earth has a literal 0% failure rate. The question is whether there’s evidence of a widespread unresolved defect after Toyota’s revisions and so far, Toyota’s own expanded recall still specifically targets certain Tundra production ranges, not every updated V35A globally.
A few isolated failures being posted online is very different from proving all updated V35A engines are fundamentally defective.
Based on Toyota's official report, they identified issues in the Alabama plant they thought were causing the debris issue. Since their Tahara plant had somewhat different procedures, it seemed to them it was unaffected. Around April 2024, they made some production environment changes. By November 2024 they also made changes to the #1 main bearing in both plants and issued the recall for all engines made in Alabama before November as well as engines made in Tahara before April.
It appears to me, they have never recalled engines made in Tahara manufactured between April and November 2024 due to lack of data supporting such a recall.
It appears to me, they have now found enough evidence that those engines need to be recalled too.
tl;dr- looks like they are recalling the last batch of engines produced without the #1 main bearing change.
Also from their original note - they did originally (November 2025) say the recall letters would go out as late as July 2026, so this might not even be anything new.

This scenario makes the most sense to me. My GX falls into this gap.
could you imagine having porsche friends, telling you porsches are super reliable, you get ready to buy your first porsche, your first ev, its a taycan, and after a while you realize all taycans have battery failures lol
or imagine being a smart guy, you buy the vw tdi thinking its good for your wallet gas mileage wise, and good for the environment, only to find out vw was cheating on emissions
sometimes you get fucked, its part of life
I think everything that was produced in Tahara with old bearing has already been recalled in Nov 2025. The doc Toyota submitted to NHTSA in Nov states that after original recall they identified two relevant production periods in Alabama - first, where manufacturing process was again improved, and second, when the main bearing was improved. For Tahara, it says, no improvement in manufacturing process happened between original recall and Nov 2025. The only improvement they made in Tahara in that time was the improvement to #1 main bearing. Assuming the bearing improvement is the final fix, this is likely the end of this recall.
From the doc
It's concerning and confusing because one thing is official documents and the other is how content creators and media have managed this information stating toyota has lied about the V35A-FTS.
While in the Nov2025 recall, they did study the Tahara Plant engines and actually disovered more debri in those engines.
The Lx had its issue and the gx had it too.
I stay on the line with what lexus and toyota Say.
Here in Panama, i have a personal relationship with lexus general manager of the carribbean and they only follow japan instructions, they do not care of USA recalls. So until Lexus actually say something of the global V35A-FTS, nothing will change.
The only thing i have in my mind constantly is why run 0w-20 in this engine and not 5w-30 like it can Run....
Then again thats another issue.
For now.
Our 2025 and 2026 vehicles are out of sight...
If there is something we will know.
The most important thing is to only follow official documentation provided from toyota and lexus and no opinions from people.
Ye, it’s confusing, but I don’t know how to interpret Nov 2025 doc any other way than:
„We (Toyota) improved the production process in Alabama at time T1 and implemented new main bearing at T2. In Tahara we implanted new main bearing at T3.
So from Alabama we’re recalling cars manufactured until T1 and we’re gonna observe cars manufactured between T1 and T2. From Tahara we’re recalling cars manufactured until T3.”
Essentially, in Tahara, improved main bearing was the only thing that changed. There is nothing that could’ve split the production period in 2 like in Alabama. They must’ve recalled everything that was built with weak bearing as part of November batch.

Toyota recalls 43,000 vehicles because engines could become contaminated
The recall affects 2024 Toyota Tundra vehicles with a V35A engine, according to the National Highway Traffic Safety Administration (NHTSA).
www.wral.com
Not sure how this will affect our vehicles or if it’s new news, but this popped up in my google feed. Article says letters will be sent to affected Tundra owners on July 6th.
That said, I’m still not too concerned. I opted for the 10 year extended warranty and if my GX is affected by the recall I get a new engine. At least that’s how I see it.
Even without the extended warranty- if there is a recall that impacts your vehicle it should be covered. Especially with the ENGINE!

Agreed. I meant if my vehicle doesn’t fall into the recall range and these engines aren’t built to last, I’m at least covered for 10 years.
yes mine stalled on the highway @ high speed. I am still waiting on my vehicle to have the engine replaced. It's been 8 weeks now
yes they are claiming my engine will be replaced, heaven knows when , but my engine crapped out
As much as I like my GX after 8 weeks I personally would pursue a lemon law buy back and get back into line for a 2027.
Lexus bought back our early vin 2023 RX500 due to issues. It is a process, you have to follow it, Lexus was professional in the process and did not fight it. We were happy enough with the dealer and Lexus to replace the RX with another 2023 RX. This time an RX350h with the proven hybrid/e-cvt.

Actually, I think this is a pretty good analysis of Toyota's NHTSA report. Here's a link to the report mentioned if you want to read it for yourself: https://static.nhtsa.gov/odi/rcl/2026/RMISC-26V320-6257.pdf
Here's the new information I could glean from the report:
- Toyota's delay in releasing this information is likely due to the amount of time they spent analyzing bearings, which only finished in late April or early May
- Toyota claims these failures are still ultimately due to machining debris, though they state that reducing machining debris wasn't the ultimate solution (which IMO is a good thing)
- Toyota claims the solution they're choosing is to change the design & specifications for the #1 Main Bearing to be more robust to machining debris
- Matching with the above solution, Toyota seems to be now recalling all Tundra engines which do not have the improved bearing, to be replaced with engines that do contain the improved bearing
- I sure hope that LS, LX, GX, and LC300 owners also will get a similar recall in the near future.
- It seems like Toyota theorized that a tighter timing chain, caused by camshafts that were too far away from the crankshaft , could be putting additional upward pressure on the crankshaft Main Bearing that could contribute to failures, so they made a production change to reduce that distance. This would also explain why it's always bearing #1, which is right at the front of the crankshaft where the timing chain connects.
- Toyota concluded that engines with this decreased camshaft distance did not statistically significantly fail at a lower rate, meaning it's likely not a major factor in failures
- [Here's where my analysis diverges from the video] Toyota also tested the improved bearing by throwing progressively more machining debris at it until it failed. Toyota states "In late April 2026, Toyota and the supplier completed the bench testing and determined that, if a piece of debris of sufficient size is introduced onto the bearing, introducing additional pieces was not a significant factor on the fatigue strength of the bearings produced during the period under study."
- The video concludes this means that the new bearing is resilient to machining debris, and that the improved main bearing will fix it once and for all
- My interpretation is different. I interpret this as "If a large enough piece of machining debris is introduced to the improved bearing, it will still fail. But if you introduce many pieces of machining debris, it will not fail at a correspondingly faster rate".
- To me, this means machining debris can still cause failures, but that there will be more time for oil to clear away debris before the bearing fails - even if that oil contains more debris - increasing the chances of survival.
- Either way, I think this is a positive design choice. You can destroy bearings with a single piece of sand, and no manufacturer designs their engines to withstand that. The increased chance of survival is a good outcome for owners, so long as it will last long enough for oil to clear away the debris.

Toyota already recalled GXs and LXs (not sure if globally or only US, Canada, and Australia?) with old bearing design back in Nov 2025. The documentation submitted to NHTSA back in Nov says the only place where they produced engines with old bearings after 25V-767 was Alabama.
