That would be wild...

Good Lord.

I wouldn't get too worried too fast. For reference, I don't personally know anyone that has dealt with a V35AFTS failure, and I know many owners of Tundra's, Sequoias, GX's and LX's with that powerplant. I'm fully aware it is a very real issue, but I'm hearing under 1% on the actual batch that is know to have issues (batch is 102,000 units ). We've raced it without issue in the Baja 1000, many of our support vehicles were running the same motor (granted many not part of the recall), it's not as widespread as it may appear. The sky is falling videos seem to be ever popular with automotive journalists covering all brands and particular Toyota as it's a fan base and platform many like to pick on, often for good cause. I have zero worries about my V35AFTS powered GX and can't wait to get some seat time in the LX700h soon.

Agreed.

The upside: Just "stole" (hired) a 15 year Toyota MDT from a dealership because he was literally going to do engine swaps for the next 2-3 years based on his PMA. He was done with dealer life and wanted to be a real mechanic again.

I have about 26K miles on my 24 LX600, except for the concerns with the TTV6, the car has been great and I think it is much quieter and comfortable than my 18 LX570. I don't think I have ever learned what has actually been causing the TTV6 failures and would be very interested in finding out if there is a way to tell if I am a candidate for engine failure.

I said it early on

Japanese V35A-FTS Bearing Issues

I know the tundras have lots of documented cases. Surprised to see LX600s with the issue too. Have any members had experience with this on their LX600?

forum.ih8mud.com

It was a known issue dating into 2023. I've heard a few things early on from credible sources within, machining speeds that produced the precariously wrong chip sizes that could get stuck in oiling ports and poor cleaning procedures between the machining and assembly process's.

Oooof, I should know better than to share such info prematurely. Hopefully this is all it ends up being.

That is good news!!

Mechanic didn't get the memo about the cover sheet on the TPS plugs.

Sounds like mostly good news, but also a reminder that the swaps are probably not quite at the same level of quality control as they are in the factory setting.

Is it possible the Japanese V35A-FTS engines are good to go outside of the recall window, but the TMMAL engines are not? Here is a confirmed failure—not of the main crank bearing (not all of them are), but of a rod bearing (which there are multiple examples of on the Tundra forum). Dealer at first tried to blame it on low oil pressure and cited the previous oil change being performed somewhere else as an excuse to deny the warranty. Toyota corporate got involved; they sent an engineer who recognized the issue and Toyota will cover it with a short block replacement under warranty. This is a 2024 truck (built in late 2023), so it is outside the recall and does not qualify for a new long block. Failure occurred at 35k miles.

Just wondering if the persisting issues outside of the recall window are now isolated to TMMAL.

I don't think it's possible to know really. The real question is: Are you comfortable in finding out by buying one?

This is precisely why when my Tacoma was still under warranty, I did EVERY oil change and EVERY Service at the dealership. I wanted there to be absolutely ZERO question to whether it was serviced properly and if it wasn't, I could point to the dealership for doing improper work.

Just curious, what criteria qualifies this failure as "confirmed"?

Mechanical failures and lemons do happen. Even with Toyotas.

Has there been a "confirmed" failure of an LX produced after the dates in the recall period?

Has there been a --single-- "confirmed" failure of a GX550?

It seems kinda crazy to me to be honest. There is no warranty requirement to do your service at the dealer. I bought my Tundra new over four years ago, and I've never been back to the dealer. All maintenance has been performed in my driveway. Warranty expired 12k miles ago. To me, that was always the reason you bought Toyotas--they didn't come with a requisite relationship with the dealer.

This is confirmed in the sense that it failed in the same way many are being covered under the recall for, and even though the dealer tried to get out of it, Toyota corporate owned up to it. Your second and third questions are basically what I'm asking: are the post-recall issues limited to TMMAL?

The funny thing is if you took it to the dealership for service it likely was serviced improperly

This is the same as having a "confirmed" kill in combat. Who the hell confirms that? Your company commander walking up to said enemy combatant, taking some polaroids and then doing the forensic work?

Just given the amount of these engines produced and the distribution of failures it's far more likely that the problem has ceased than still occurring given the sounding board of the internet.

 

[rexington14]

Post recall issues in an LX are unheard of AFAIK. GX550, again, unheard of.

The "infamous" tundra failures spreadsheet lists 3 (three) 2024 year tundras that failed.

Toyota sold 159,528 Tundras in the US in 2024.

Even if it's still happening the risk is so low now that if you are in fact a human being then you more than likely have much bigger things in your life to worry about than this.

Just buy the vehicle if you want it. Hesitating -just- because of this issue is insane.

Those were all built in late 2023. Same with 2024 Tundra in the screenshot I shared. Still, it’s outside the recall window.

If the build date were within the recall window, this truck would receive a new long block per the recall. <<-THAT is what confirmed means IMO.

Even if it's still happening the risk is so low now

Yeah low risk. Still, they’re happening at completely random mileages…some on the spreadsheet didn’t spin a bearing until after 50k miles. My risk tolerance is far higher with investments than it is with vehicles lol

I bought the truck when I had a concern about maximizing potential resale value if I needed to sell it for whatever reason. Also, Toyota can't come back to me and say that I serviced the vehicle improperly when there is a paper trail of all service done, associated with the VIN, by the authorized dealer.

Personally, I'd pay more for a used vehicle that has full dealership service records that shows that the service was done on time every time, and factory Toyota parts were used.

I get it, but I prefer to do it all myself so I know it’s done right. I’m done with absolute crap service from Toyota/Lexus dealers. There is an inherent conflict of interest in trusting a dealership to keep me from needing a new vehicle when they always want to sell me a new vehicle.

I keep notebooks of service records as well as every fill-up in the console of the Tundra and the 570. I enter details on carfax.com with every service item. I would value this from a fellow Cruiserhead DIYer far more than dealership records. Those places have earned their reputations, IMO.
