Tundra engine recall - interesting news

Design flaws can still be evidenced by situational failures only.

Design flaw never meant 100% failure in any quality management system. Design flaws can lead to increased failures worse than expected

Man honestly, I just looked up sales figures and saw Ryan's spreadsheet-- he literally has 134 trucks listed as failures and I am sure he is not capturing all of them. Toyota sold 219,614 Tundras in 2022-2023- of those 134 known failures? that is less than .000610 percent or way below average for engine failures for other makers. This has been blown way out of proportion by this very forum, this is laughable. I attribute failures to a bad batch of blocks, week CNC tooling that gets replaced or something other than a known common problem.

Toyota will make this right if you actually suffer from it but this is nothing to be concerned about.

 

The oil passages and order of galley feed on the FA are in the exact same order of the V35. Both engines feed the left side of the engine prior to to feeding the main galley. Oil starvation issues will always exist, to a certain degree, in a wet sump engine, and this is why a good oil system ALWAYS feeds the main galley first. It’s a design flaw that was knowingly incorporated and was done so as it’s cheaper to manufacture.

Now, is this the sole reason for the issue? Probably not, but as with most disasters, it’s part of the puzzle that contains several facets that contribute. Had the FA engine been designed with priority main oiling, the inadequate baffling in the oil pan might not have shown up so easily. However, it does, because the left side of the engine is first in line for oil, with the mains being second. Does this contribute to the V35A failures? With some chips restricting the second in line for oil galley, we should seriously consider it.

 

that's fine, believe what you want, no problem.

for now, Im going with what has been published* considering the amount of documented failures to total trucks in service, that's up to what 400K tundras now?

*that may change if actual information becomes available.

 

The market doesn't value used 3rd Gens. Their depreciation is much higher than you'd expect from a Toyota truck.

 

What you are saying doesn't really make sense, the cylinders themselves have oil squirters? correct? most all turbo engines I have seen us forged crank and pistons along with individual oil squirters for the cylinders so that they should never reach a lack or oiling. The bearings could be another thing, but I really do not see how with 7 quarts of thin ZERO weight oil this would be an issue.

 

in fairness, the entire used market has and is changing, as evidenced by 10K off the new ones.

there is some of your resale loss right there realized at the time of purchase.

 

You do realize that those results are from owners filling out a Google Form and not Ryan capturing the data himself?

As someone else said, the novelty has worn off and there is no need to continue to report failures, either here or on the Google Form.

There are plenty of Sequoia failures as well that were not tracked by anyone in the community.

 

ha ha , you owe me $$, you said "not Ryan"

 

Dry Fill - 9.7 qts.

 

Okay another member said it could capture 10 percent so lets say there is actually 1300 failures? that is still only .0059 which is less than 1/2 of a percent. Me think you all need to come up with other reasons to hate the 3rd Gens.

 

You should be a math teacher.

 

Isn't the space enough to make it not your trademark?

 

I thought about it, do love Math and love stocks/ bonds and Roth IRAs. I don't return some Nancy Pelosi numbers but I do alright.

So, they have recalled 102,000 trucks but not all trucks will fail and not all recalls will need a new engine but get one out of goodwill. Toyota is doing the right thing with recalling potentially effected trucks. They did not have to do that.

However not all recalled trucks would fail nor require a new engine. Toyota will replace them which is good on their part.

 

1) Jabroni Toyota rep says it's solved.
2) More engines fail.
3) Doubts Jabroni's claims that it's solved.
4) This "doubt" = salt on wounds

 

.0001% would be 1 in a million. Let that sink in to your calculations.

 

107 pages later, I don't think this is interesting news anymore. Yawn.....

 

it is .59 percent or less than 1 percent that have failed so far. Regardless that failure rate is not catastrophic or still less than the average Ford that blows up.

 

So we did just go from .0006% to .5%?

That’s a 1000x increase in just minutes. Seems alarming.

 

True and fair point, but I really think it's disingenuous to pretend that none of the depreciation of the early 3rd Gens is due to the recall, and that none of the [preposterous] increases in Gen 2 resale values are either.

And I'm not saying you made that claim, but others seem to insinuate that. And to be clear, I'd rather it not be that way. I wanna scoop up another 2nd Gen on the cheap, and that ain't happening any time soon

 

It makes sense, the oil squirters are fed off the left side oil galley, they do not spray the piston bottoms constantly, but rather require a certain pressure to crack open. Toyota states right in their literature that this is to prevent low system oil pressure. When they do begin to open, oil flow taken up by the first to be fed left side oil galley increases and leaves the second to be fed main oil galley looking for something that isn’t there.

 

come on, I didn't put it in percentage form but left it fraction. Give me a break.

 

If you’re going to be a math teacher - you can’t tell me .6% and .0006 percent are the same. Even if you didn’t write percent it’s still 10x off. Blame me if you want but I didn’t post the wrong info.


You say failure rate is 1 in 180,000 and I’m the bad guy.

 

Gee thanks and Math teacher for me would mean a 75% pay cut, so I need to think post-retirement.

 

Your employer will be relieved to know you didn’t qualify - the retirement for teachers is solid if you can get that far.

 

Do you have data to support the rates at which the average Ford blows up? I'm not trying to be snarky with this question, but it's statements like this that seem very dismissive of this blunder by Toyota.

Toyota was always head and shoulders above the big 3 when it came to reliability (and maybe they still are), but once this recall came out it's completely reasonable to question if that's still the case.

To just blindly say "they're still better than Ford/GM/Ram, because Ford has cam phaser problems, GM has lifter problems, and Ram has the hemi tick" seems to be the kind of attitude that just accepts Toyota stooping to their level.

Those company's problems may very well be just .0001% of their trucks too, for all you or I know.

 

1300/102000*100 = ?

It's still only 1.27% which according to many is well within normal failure rates for auto engines. How on earth do you come up with .0059? and how is .0059 less than 1/2 a percent?


Please take your seats class...

What is a percentage?
In mathematics, a percentage is a number or ratio that represents a fraction of 100. It is one of the ways to represent a dimensionless relationship between two numbers; other methods include ratios, fractions, and decimals. Percentages are often denoted by the symbol "%" written after the number. They can also be denoted by writing "percent" or "pct" after the number. For example, 35% is equivalent to the decimal 0.35, or the fractions .

Percentages are computed by multiplying the value of a ratio by 100. For example, if 25 out of 50 students in a classroom are male, . The value of the ratio is therefore 0.5, and multiplying this by 100 yields:

0.5 × 100 = 50

In other words, the ratio of 25 males to students in the classroom is equivalent to 50% of students in the classroom being male.

 

good lord guys

set down the bong and bourbon and step away from the math, lol.

ok , back to "interesting news"

 

You can look at warranty work costs. Ford is off the charts. Ford 3.5%, GM 3% and Toyota 1%. Ford has had to restate and reserve against not getting the costs down several times. Farley brought in to fix it and hasn't.
