Tundra engine recall - interesting news

They should just give everyone a 10 year 120,000 mile power train warranty and call it a day. Replace entire engines as needed.

 

I don’t think we’ll ever know but IMO if the failure rate was really that low the worlds most profitable car manufacturer would not be replacing 102,000 engines . .5% failure rate is actually considered normal .

 

I disagree with you. It's often when corporations and others will use slight word choices like this one to save costs and give you a "new to you engine"

I assume you don't want to keep this truck?
I would really try to just turn it back in to the dealer when it's due and have them do the recall themselves!

It depends on your lease agreement though, does it say anything about recalls and that you must complete them before turning in the truck?

Engine recall isn't a simple thing, it will probably take a couple of weeks minimum... You can try to play stupid and just show up and say you didn't know and do your own damn recall by yourself. You didn't lease this truck to waste your time and deal with the recalls bs.

 

Everybody also hoped that Toyota would take a quick look at the engines that robots are milling, and won't first make few hundred thousand of those engines (hybrids included) before realizing that they're no good

 

He was a devoted member of this forum, with a Toyota technical tas subscription, and was very helpful to everybody and provided very good information.

Ryan bought a replacement short block and took it apart in his living room to inspect it, and showed the world photos of the machining debris that's causing the failures.

But Toyota corporate thought that Ryan knew too much and one day they declared him an excomminicado and he was never seen again.

Legend has it that every new long block engine for our Tundras will be personally inspected by Ryan for metal shavings before it's installed into our trucks.

 

I agree with your first sentence, but I’d up it to lifetime for this specific issue.

Replacing as needed is wild. I’d much prefer the option of scheduling it at my convenience rather than having it fail while towing my boat or on a family vacation.

I still think Toyota should offer the fix to all vehicles that are affected. They should also announce their intention, if they have any, of including the hybrids. Just let us know something.

 

Ryan also strongly believed that he knew why engines were failing and this knowledge kept him from accepting that it could happen to his engine.

He was convinced that he could drive it hard, change the oil often and use higher octane gas.

I am sorry to hear that this didn’t hold up and he has become that 0.001% of the failures.

I did admire his determination though.

His recent info about the machining burrs has really opened my eyes to what is happening inside the engine and this is very appreciated!

 

Maybe the failure rate isn't as low as we all think...

 

I’m getting the vibe that it’s just a matter of time for all the 22’s and 23’s… and maybe the 24’s

 

This is obviously a huge part of the puzzle... Will every engine in the recall range and even some beyond it eventually fall given enough time? Or might some have been properly cleaned, etc.

 

Ya true. The option to replace at your own discretion would be nice. Some may want to put it off long as possible to rack up miles. (Cause they kinda owe people for depreciation too, that would allow them to stay in their trucks longer)

 

For sure. That’s what makes the decision to keep or sell so difficult.

 

Good point, it’s kinda like getting a new truck. Also, I wouldn’t want my truck to be the first in at my local service department. Let the team get some experience, maybe they will be less likely to make any mistakes.

 

Caution wild guesses ahead....

IMO, and I'll be happy to be wrong, these failures are a lot more complex than simple machining debris. Debris contamination in the manufacturing process is a simple QC fix. Even if you're not retooling, a simple inspection and flush/bath solves the problem. Seems a lot more likely to me that this is a design and materials problem. And the materials problem is causing the bearings to slowly disintegrate. There have been too many Blackstone oil analyses with elevated silver (indicating to me that the bearing(s) is/are slowly failing) for that finding (elevated silver) to be some kind of coincidence. Is it heat? Improper tolerances? Dissimilar metals not getting along internally? Improper design of rotating/stressed parts? Oil starvation due to too small journals? I'd say it's most likely to be some combination and interaction of all these things and more. And IMO that's why we are still seeing failures in the 2024s. The design of this motor is going to have to change, and apparently that's going to have to include more than a redesigned bearing.

 

Thin oil isn't helping either.

 

Sounds good but it doesn't satisfy the safety recall.
Leaves You open to something very bad, risk event happening - i.e.- someone's engine going in a very bad place. Freeway, towing up a steep one lane, ... and Toyota being sued.
Your engine is great, smooth, powerful .......until it isn't.

RG gave what I thought were excellent warning signs leading up to the failure, for those that care. And for someone that was as anal as RG to use top level gas, and short oil change levels to try to prevent this to no avail. Sheesh....
I would be following regular warranty time periods for oil, cheap 87 octane Gas.
Drive the crap out of it. Your engines coming out at some point whether you like it or not.
And at some point when they have engines on hand and time - you will be forced to do it.
Its a new truck design and Toyota at that. This is ridiculous.

The winners IMO are the leasee's. The risk factor if I was a leasee being the engine fails and the truck is out of commission for X months ? while my payments are ongoing and Toyota gives me what kind of vehicle ...in Canada to use?
Just saying. At least you know you will be handing it back to them hopefully before they pull your engine.

I want to see this resolved.
I'm anxious to see what the Tundra refresh looks like, (if they are still making it) to see if they address the shortcomings I found.

 

Could be. It'll be interesting to see this play out as more pictures and more speculation circulates. I suppose only the Toyota engineers really know anything at this point. With the 2024s now failing, I'd be surprised if the mid model refresh didn't include an updated version of the 3.4TT with redesigned internals. The real test is whether any of these new long blocks will start eating bearings. If that happens, Toyota will be walking down the same road as Hyundai with their 2,000,000+ engines being replaced whenever they fail.

 

Ya know it certainly seems like they would KNOW they figured out the problem if they're replacing whole engines. The length of time suggests this as well.

 

Scanning...

 

Thin oil with massive amounts of fuel…

 

They thought they had figured it out 16 months ago.

 

Fixed.

 

I've used Blackstone in the past for my motorcycles and they do ok.

I do, however question the whole silver thing. Blackstone claims that it could be a sign of bearing wear but Speed Diagnostix (another oil tester) says that silver is not in bearings and they don't even test for it.

I tend to lean to the Speed Diagnostix explanation but I'm no expert.

That’s not what they said.

 

I stand corrected.

Is Toyota using silver in the bearings?

 

I don’t know what else would be dumping silver in the oil. Do you?
