V35A-FTS bearing issue?

[OGBeno]

It is amazing that we went from this issue being 'statistically irrelevant' that it shouldn't even be brought up to the ashtray engineer. To a large and very significant recall on 100k+ trucks with no known remedy. all within 24 hours.

Fake news everywhere I tell ya!

Ashtray engineer has been fired. He went to work immediately for Phillip Morris.

I feel bad for the customer that had a tech throwing all of the to be re-used engine components on the ground with some paper towels as a barrier? That would not surprise if they were one of the people on their 2nd blown engine.

Yeah that's a big downside to all this. If it was a long block, maybe it wouldn't be quite so bad, but who knows how competent the tech will be. You might get an uber meticulous 30 year Toyota tech... or maybe not.

Here's the full video if anyone's interested:

Holy hell, it just keeps on getting worse for the repair. The parts pile goes down the length of the truck and even into the bed. No wonder why it costs 30k to fix it.

Is it possible that the date range is the engine manufacture date? Or, more specifically, the machining date? Could a 2024 MY block have been machined as early as Feb 2023? When did the 2024's first get assembled? August of 2023?

Being that Toyota uses JITM (Just In Time Manufacturing), it is safe to assume that the engine in a specific vehicle was produced within a week of it going into said vehicle...

I've seen at least 10 2024 model year Tundra/Sequoia with failed motors...the lowest mileage being around 1,400 miles in a Sequoia...

The lowest mileage failure that I'm aware of and confirmed via VIN was a 179 mile 2023 Tundra Capstone...

The ones that I've seen locally have take up an entire bay just for the engine parts...so you're talking about at least 3 8-ft folding tables...

I’ve lost that warm fuzzy feeling. The M35A-FTS makes me limp

A big problem that I see is that the issue is still happening to 2024 models after the end of the recall notice. The metal shavings issue was found out more than a year ago, and they supposedly already fixed it. So why does this notice extend out past the initial discovery in early 2023?

Obviously there now is a remedy. 100,000 vehicles don’t get recalled with no solution available.

@OSS I'm fairly certain that the regulations for advising owners of recalls don't include a requirement to "only notice recalls if there is a solution available".

The OEMs do data analysis to determine if there is in fact a defect (or safety-related defect) before they notify NHTSA and customers.

Recall regulations are here:

What Is a Safety-Related Defect?
The United States Code for Motor Vehicle Safety (Title 49, Chapter 301) defines motor vehicle safety as “the performance of a motor vehicle or motor vehicle equipment in a way that protects the public against unreasonable risk of accidents occurring because of the design, construction, or performance of a motor vehicle, and against unreasonable risk of death or injury in an accident, and includes nonoperational safety of a motor vehicle.”

A defect includes “any defect in performance, construction, a component, or material of a motor vehicle or motor vehicle equipment.”

Generally, a safety defect is defined as a problem that exists in a motor vehicle or item of motor vehicle equipment that:› poses a risk to motor vehicle safety, and› may exist in a group of vehicles of the same design or manufacture, or items of equipment of the same type and manufacture.

NHTSA hasn't loaded this new recall onto their dashboard, yet: NHTSA Recalls by Manufacturer | USDOT Open Data - https://datahub.transportation.gov/Automobiles/NHTSA-Recalls-by-Manufacturer/mu99-t4jn

Manufacturer Recall Number: 24TB07
NHTSA Recall Number: 24V-381

I take all this to mean that perhaps they (Toyota) don't have enough data yet on MY 2024 to extend the recall to those vehicles.

You do know that this is a very old engine design-- ladder frame bearing cap that is machined in conjunction with the block. Toyota diesels have been this way since at least 1990. One of Toyota's greatest diesel engines-- 1HD-FTE -- is designed this way. Almost all new engines are designed this way as well.

I'm going with a process issue not a design issue.

So a process issue both in the US and JP.

Regardless of where the engine is assembeled, I'd bet the casting and machining are done in the same location for all.

Ok so there’s a recall notice for over 100,000 Tundras and there’s no fix available, so everyone returns their vehicle to the dealership and leaves it there forever.

 

[ikarus]

All we know is the official press release said "Toyota is currently developing the remedy for this issue. Owners of involved vehicles will be notified by late July 2024."

Just keep driving it. I am not sure I understand what the issue is. It's not so critical like the Takata shrapnel bags..

 

[UZJ100LC]

that truck will never be the same ever again. what a mess. i would not want it back if bought it new. And I would never buy it used if I saw it had this service history.

 

[Sandroad]

Looking at the video in post 142 has me thinking the recall remedy is not going to be a short block. What a mess. I’ve rebuilt an engine and a transmission as an amateur mechanic so I know first hand how hard it is to get everything right. This will be a tough one for Toyota.

They have to assume worst-case, like a driver with no mechanical awareness, clueless to the heavy clunking going on up front and trying to merge into a tight traffic gap when it fails and they get hit.

Similar to the passenger side seat belt recall for the 200. They had no parts for months, but unlike the Tundra there was a 'do not drive' notice IIRC. So I guess we were supposed to park it until they had the replacement. For the 22/23 Tundra, there is no 'do not drive' component to the recall letter. At least not in the release that's been posted. Don't know what the notification will say that the owners of the affected vehicles will get.

Could be multi-faceted: inspect oil condition to see if there's metal. If so, pull and inspect the bearing. If bad, replace the short block. With as long as it took them to publish the recall notice one would think they were doing analysis of the failed units and have an idea on how to gauge probability. I would hope there would be an extended warranty component to whatever the repair mode is.

There's a collateral effect for all other Toyota owners: dealer appointments will be pushed way out as 100,000 Tundras return to the nest. Just like is happening at Ram dealers right now with the Cummins recall.

The issue was noted in an earlier post in this thread where a service record was attached. The record showed the truck shut down on the highway with a locked up engine. There are many circumstances where that could be life-threatening. Hence the safety recall. This is not just an inconvenience, though I can think of lots of situations where it would in fact be an extreme inconvenience.

I'm only acknowledging the fact that the recall didn't instruct owners to stop driving affected vehicles. Your argument is with Toyota and NHTSA.

The 200 passenger airbag/seatbelt recall was not a “do not drive”. It was “Toyota recommends no passengers sit it the front passenger seat” (until the recall remedy is available ).

We don’t know what the recall notice to owners in July will read. All we know so far is
‘A loss of motive power while driving at higher speeds can increase the risk of a crash”

Ok, so stop driving yours then if you're worried about it. Just like another day on the freeway for a Jeep.
