Second Toyota engine recall delayed because company doesn’t have a fix for problem
Posted on 5/11/26 at 6:24 pm
Posted on 5/11/26 at 6:24 pm
Affects Tundra, Lexus LX & GX.
——-
Next, another recall was issued that expanded the first recall to include 2024 model year Toyota Tundra and Lexus GX 550 vehicles.
The problem stems from a faulty production process that leaves machining debris inside the engine. This debris may prevent the vehicle’s crankshaft from rotating while running. The debris build-up, according to Toyota, can cause the main bearing to fail, and the vehicle may stop while driving, increasing the risk of a crash,
As part of the first recall in 2024, dealers were instructed to replace the engine assembly; however, that failed to adequately resolve the problem according to NHTSA.gov documents from Toyota. Compounding the problem of not having an actual remedy for the problem, Toyota is unable to provide an accurate estimate of just how many of the vehicles with the specific engine may actually be affected.

Woof...I expect better from the Japanese.

Toyota isn't built for this new regulatory environment and they're out of their historic element when it comes to engines.
Just look at many of their larger bulletproof engine offerings, which were trustworthy, simple to work on, and drank gas.

I just bought a 2021 Tundra a month and a half ago, and it took me forever to find one with decent mileage at a decently fair price because people were scooping them up left and right.

Quality really went to hell after the pandemic. I am afraid to buy something newer for that reason

Google Gemini said the following on engine specific recalls since 2020. I could try to drill it down to severity/catastrophic I suppose.
Ford: 58
Hyundai and Kia: 44 (I sorta know why they are grouped but OK)
Stellantis: 31
GM: 27
VW: 19
Toyota Lexus: 12
BMW: 10
Mercedes: 9
Ford: 58

So they are replacing engines with machining debris left in the engine with new engines with machining debris in the engine. And they don't have a fix?
I am not the brightest person but it seems like the fix is pretty simple.

I think they are trying to not replace the engines
Posted on 5/11/26 at 6:36 pm to Teddy Ruxpin
What are the actual recalls on though?
We talking a software update? Total engine replacement? I'd like to see the details

You're in luck. I asked again about full engine replacement recalls. Obviously you have to keep asking about # of vehicles at issue and stuff like that to get full context.
Hyundai and Kia: 12
Toyota Lexus: 3 (I think all of these from the machine debris frick up since 2024)
Ford: 3
GM: 2
Honda and Acura: 1
VW: 1
Take it with a grain of salt on numbers since AI has its issues.

From what I’ve read and saw on the internet, the gear heads are calling BS on this. It’s not machining debris, it’s a faulty design and use of the wrong oil. A thicker oil can remedy the problem.

I'd have to watch it, but as a mechanical idiot, could you consider something that can be easily fixed with a heavier oil a "design flaw?"
If you update the manual and people use the "correct" oil and the problem is "solved," it doesn't seem like a design issue but again, I'm an idiot.

The lighter oils are used to help with fuel economy and to meet targets.
Most modern engines can’t work properly with heavier oil.

I can’t find a decent pre- recall lx. Currently driving the GX with 35k with zero engine issues.
I want a larger vehicle so about the buy a post recall LX and hope Toyota addresses the issue when the time comes. I refuse to buy ford or gm.

One can’t help but wonder if we are really ‘helping the environment’ with these more ‘fuel efficient’ engines if they don’t last and we have increased the waste streams and replacement part production.

for the love of God, bring back the 5.7 V8
hopefully my sequoia lasts until they put it back in the landcruiser

Speaking as an actual retired auto industry powertrain engineer who's forgotten more than these "internet gear heads" collectively know, there is no such thing as a "thicker oil" fixing catastrophic main bearing failure simply through film strength/thickness. It's BS.
What a thicker oil CAN change though is how an electro hydraulic VVT system advances and retards the cam at operational envelope extremes. If they are letting combustion pressures get so high at the extremes that they are hammering the crap out of the bearings, then a "thicker" oil MIGHT be enough to cover up a design flaw by cutting the extremes off the retard/advance curves. I doubt that is the case here though.

Don't think a software update can take machining debris out the engine baw.

I’m just waiting until my LX gets caught up in it. I know it’s coming.
