According to Lexus, I (we) are supposed to receive some sort of correspondence reference the recall this month. I am curious what Lexus is planning to do about the recall. While not ideal, total engine replacement sounds better than replacing certain components since I have 3x,xxx miles on my trouble-free LX already.

I know there are other threads that have been started about this, and most have been told engine replacement. My recall notice stated the "fix" was not yet known and that additional info would be available at a later date.

What says you?

 

42K here. Looking forward to a new engine.
no issues or problems otherwise.

 

My engine in my 23 LX 600 blew up two months ago. Had 42k miles on it. Should be getting a new engine installed by the end of the month.

I was originally told by my service advisor it would take six months to get a new engine from Japan.

Anyone on here get a new engine? Did the LX drive the same or anyone notice any differences with the new engine?

 

What were the symptoms (if any) prior to the issue and was it dead-in-the-water after the event?

Please read the source, not hearsay as a lot of people mention things and are not quite accurate.

Transfer original components from original engine to new engine

a. Transfer the following components from the OLD engine assembly to the NEW engine

assembly.

• Engine Wiring Harness

• Generator

• A/C Compressor

• Drive Belt Tensioner

• Drive Belts

• Misc. hoses/brackets

That's it for old stuff.

Pretty much everywhere that oil has gone to will be replaced.


​​​​​​​The engine assembly is this part, 04004-23170 Engine, Assy LX (Not returnable).

The whole thing arrives in a crate, unhook the seized one, hook the new one and register. no major mess with internal engine components.

 

However, this is the resolution for the first recall. Do we know yet that the second recall will use the same resolution?

I have a 2024 model with a 7/24 build. Not part of the second recall. I'm assuming there will eventually be a 3rd recall that covers mine. But who knows? I don't think we know if or when the root cause has been fixed.

I would love to know what the actual failure rate is for these V35a engines across all model years. I don't think this is public information unfortunately.

 

I would not count on everyone getting a new engine. Lexus still says that they will communicate a "fix"....they do not say necessarily a new engine. They are replacing some engines as they need to do something right now. I find it very hard to believe they can produce, ship and install the number of engines needed to resolve the vehicles in the recall (which is expanding...). We hear of a handful of examples of people receiving new engines, but they are small numbers with 3 or 6 month waits and 10 days for a dealer to install one engine. No way can this happen with thousands of vehicles in a reasonable timeframe. Just does not make sense. The wording of "fix" indicates that Lexus knows this.

The bigger issue is that Lexus does not really understand the issue. Logically speaking, how can residual debris in an engine cause failure 40K+ miles later after multiple oil changes? How can the residue left in the engine occur at multiple manufacturing facilities? The debris is long gone by this point, or if stuck in the oil galleys, would have cratered the engine very early in the life of the engine. Just does not make sense. I have seen pictures of the damaged crank bearings......it is catastrophic. It did not occur over time. If Lexus truely thought the cause was engine debris during manufacturing and the problem has been solved, they would say the "fix" is a new engine....period. I can't blame Lexus for the lack of transparency as they have a business to run. I also have confidence in the company to do the right thing. At this point it seems they don't know what the right thing is. We will see.

 

I just saw a comment from a Toyota mechanic in Pennsylvania (on a YouTube video) who said he personally has replaced nearly 50 short blocks in Tundras over the past few years. Toyota evidently allots 15 hours per replacement, which is woefully less time that the job actually takes. He also mentioned that they are seeing failures on engines with as few as 400 miles now.

It’s painfully obvious that this issue is a design flaw, NOT “machining debris in the engine from the manufacturing process.” Your reasons (which I have also said in the past) are 100% correct and valid. Debris in the engine will be washed around/out quickly when the engine is new, and will be caught by the oil filter and/or be found in the oil pan as metal shavings/sparkly debris. Slag doesn’t just lie in wait in the cracks and crannies of an engine for years or tens of thousands of miles and then suddenly appear and cause main bearing failure, while sparing the top end of the engine any issues (cam lobes, lifters, etc.).

The other thing that people don’t fully see, perhaps, is that the majority of these failures are happening while the engine is under load — for Tundras, that means towing, four-wheeling or other times when the engine is in heavy use. For LX600s, the failures I’ve seen (especially over at IH8MUD) have tended to be when driving at highway speeds.

 

Toyota has been actively suppressing information out there about these failures. I am hearing that their legal team has even threatened certain forums who have posted information about these failures, as well as technical information (i.e. info on main bearing clearances) that is actually available through Toyota technical documentation and manuals.

The fact that they are rattling their legal sabers to suppress information and have info taken down off the internet, is telling.

In my opinion, it’s only a matter of time until the two YouTube videos from “I Do Cars” and “The Car Care Guru” — both HIGHLY knowledgeable and reputable experts on engines — on the V35 engine, will be forced to be taken down. Toyota/Lexus can’t help but see these types of expose videos as very damaging. But….the cat’s already out of the bag. It’s gonna be hard for Toyota/Lexus to put this genie back in its’ bottle….

 

If If I were in the market for one of these suspect vehicles, I would try and hold off as long as possible.

I am not convinced they fixed the problem or even know what the problem is.

In a perfect world, I would wait a couple years and see if the problems have been resolved. Such as gamble at a high price point.

i hope the problem is fixed, but am skeptical.

 

My Lexus LX had no prior symptoms before the incident. While driving on the freeway, I suddenly felt the vehicle lose power, and multiple warning lights illuminated on the dashboard. I was able to pull over safely. Afterward, the vehicle would start, but it was clear something was wrong. I had the vehicle towed to my local Lexus dealership.

 

Lexus said they would have the recall remedy in January……

 

New one just showed up in the Health section of my App; https://static.nhtsa.gov/odi/rcl/202...6V094-4382.pdf

Potential Number of Units Affected: 4,374

Problem Description:

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2025-2026 Lexus LX600

vehicles. In the event of transmission solenoid failure, the communication may fail between the

transmission electronic control unit (ECU) and the engine ECU, resulting in transmission damage.

Consequence:

A damaged transmission can cause a loss of drive power, increasing the risk of a crash. In addition, a

damaged transmission can leak transmission fluid, increasing the risk of a fire.

Remedy:

Dealers will update the transmission ECU software, free of charge. Owner notification letters are

expected to be mailed April 25, 2026. Owners may contact Toyota's customer service at 1-800-331-

4331. Toyota's number for this recall is 26LA01.
