Toyota 3.4L TT recall

That’s not helpful. I thought you had the answers for us?

 

All I can do is offer my opinion.

And my opinion is if I were you, I wouldn't be worrying about purchasing new models so much because you have a 2017 that will last a very long time.

 

I have to buy something new towards the end of next year when my oldest kid starts driving and gets one of ours as a hand me down.

 

I would personally say it depends in when the issue manifested and is detected, not necessarily when the truck rolls off the assembly line.

 

2022 started with Turbo waste gate failures and then started the complete engine failures with main baring. 2025 model Tundra still got engine failure. Still no sign of resolution.

I remember on one of the videos of the Toyota expert CarCareNut said Turbo engines will never be reliable as N/A engines. So we 5th gen owners having an engine that is more reliable (per Mr CarCareNut) than a 5.7 Tundra/ Land cruiser, 4.6 GX460 it would be a hard one to downgrade to something like 3.4TT Tundra / GX550 or 2.4T Tacoma/Lnd Cruiser.

 

What happened with that? I don't hear much about it anymore. Seemed like a very small percentage of vehicles.

As a result of machining debris causing main bering failures. As I understand it (maybe I'm wrong), this was associated with the way 1 plant in Alabama was manufacturing the blocks.

Are they? I thought 2024 and 2025 had not been recalled and the resolution for the affected vehicles was block replacement.

Yet Car Care Nut still bought a 2024 Tundra with the 3.4TT. That speaks volumes.

 

I would not buy the first couple years of any new model. But that's just me.

 

Back in the days when Toyotas were typically underpowered and simpler, buying a first-year model wasn't risky. But the world made those days go away.

 

I agree.

However, I think statistically most problems today are software related and most fixes involve a software update.

 

That, and CAFE crap. For example, the only reason the Tundra V8 went away was the necessary pursuit of another MPG or two. In today's world, CAFE is becoming less relevant IMO.

 

I doubt, I believe the LX600 is fully made in Japan and yet have the engine failures.
If I'm not mistaken I saw a youtube short video of LS500 with 3.4 twin turbo had same issue.

Yes sir, first 2025 Tundra engine failure reported in Nov. Not only 2024 & 2025 gas models have engine failures who are still eligible for full long block, there are Hybrid owners reporting engine failures and not covered in the recall list. I believe they are treated as regular power train warranty customers getting engines repaired.

 

I think your average customer wants better mpg's as well, especially considering the variability of gas prices......even if it's only a few mpg's here and there.

Toyota has been saying for a long time that they plan on offering every one of their models as a hybrid. Whether that's a CAFE based decision or a consumer based decision is debatable. Probably a bit of both.

 

That’s the dilemma. How long do we need to wait?
Remember when companies actually did testing before releasing to the public?

 

If the truck breaks it will be YouTube gold for him.

 

Yup. There’s no way that it is debris in the engine. No one would keep producing failing engines for four years without changing how they clean the engine blocks. It has to be a design failure with the bearings, oiling, etc.

It’s been happening since model year 2018? That’s 7 years. WTF Toyota.

 

You actually think Toyota didn't test before releasing? Cmon now

 

They obviously didn’t test enough and they are paying the price for it now. Replacing 100K+ engines is going to be painful.

 

You want us to believe that consumers are that obsessed about mpg because of gas prices yet they have no problem with keeping buying vehicles that have increased 30-40% in prices in the past 5 years?

I don't know what mpgs your vehicles get but Toyotas are not getting 30-40% better mpgs ditching their NA 4,6 and 8 cylinder engines, never mind recovering the cost of the price increases.

LOL.

 

Not enough tangible returns on these next-gen Toyota truck powertrains, and way too much in both passed-on costs & headaches to the consumers. Toyota hopefully will right the ship with the TTV6, but unfortunately a lot of folks (100+ and counting…)will be at the mercy of of their local dealership service techs to correctly install brand new engines.

Quietly observing the fiasco with Tundra…I’m not yet convinced of the wisdom in swapping out a 1GR V6 for a small-displacement four cylinder with eight injectors, a turbo, and an electric motor powered by hauling 300lb’s of nickel hydride requiring it’s own cooling fan & serviceable filter, just for a couple lousy mpgs.

 

The thread is just full of laughs. Much appreciated.

 

Lotta lead poisoning in this thread for sure lol

 

I've totally been missing out on this thread.

I think my favorite post was when somebody claimed that they had to buy a brand new vehicle because one of their kids was going to need a vehicle in the future. As if you couldn't buy the kid a used vehicle.

Or, do like people in my area have been doing forever and let the kids save their own money and buy their own piece of shit car and learn how to work on vehicles.

 

Good luck being a young driver working on the turbo engines, computerized everything, and gardenwalled vehicle networks. LOL.

 

I swapped mine for one with a wider angle and better low light and it's made backing into dark spots way easier. Just make sure it plays nice with your stock screen.

 

I manage to maintain my vehicles on my own without any special knowledge. I'm also pretty sure you can still buy used cars that don't have turbos.

Eventually, it definitely will suck trying to work on our own vehicles, though. It's already worse than it was when I was young. But, it's still doable, for most vehicles.

 

I'm still confident this is detonation, knocking the rod bearings out. In the video you can see the rod bearing mushroomed out, blued and trashed. This is exactly what happens after detonation. Turbo engines are VERY sensitive to detonation due to the super high heat from the turbo. The twin turbski tundra has an air to water intercooler, but me thinks the heat isnt being removed well enough, or the timing and fuel tuning isnt quite good enough, and we are still seeing detonation. Detonation which knocks the rod bearings out and causes the knocking engines which puts metal in the oil.
Could there be a tolerance issue? Not sure.......
Could there be a bearing manufacturing issue? Not sure.......
Why else would they change out the whole long block? Not sure......
Regardless of how you spin it, the issue looks more like detonation than anything else.

 

OK Boomer.

 

Wouldn’t Toyota be able to fix that with a tune or premium fuel?
