Reports of engine failures?

Maybe I missed it. What did Toyota find that was causing the engine failures besides the early waste gate problems?

 

Could that be because few post March 23s have hit 27k

 

As far as the turbos (not commenting on an other aspect of the engine), I’ve tried to think a lot about the risk.

As a younger fella I began buying my cars when turbos were becoming a primary solution to fuel economy goals. So my friends and family were buying engines that were also turbocharged. Between the lot of us we’ve put down quite a bit of miles powered by turbo engines.

Out of us all I’ve only seen one turbo fail and it was a Hyundai. My brother drives the wheels of his ecoboost 3.5L F-150, and it’s still going strong. I had a WRX that I beat the snot out of having fun (lol yeah I was a boy racer wannabe), and no turbo issues. My current ecoboost Ford Ranger is still going strong.

Every single one of these vehicles saw significant gruff from naturally aspirated purists on forums. I get it. Naturally aspirated is one less problem to go wrong. But I’ve seen a lot of turbocharged miles and the industry by and large has it figured out. I committed to full synthetic oil changes every 5k miles, oil filter at every interval, premium fuel (I’m not convinced this is helpful or not, except for engines without port injection), and trying to follow turbo cooldown guidance after highway speeds. It’s paid off for me.

All of what I said is anecdotal. Its opinion. Just adding to the conversation and stating that I do not inherently distrust turbos. Outside of racing applications and 15+ year old metallurgy, I think turbos overwhelmingly work well, they last long if cared for, and can be trusted. In my opinion.

 

Are the “2nd gen failure cheerleaders*” in the room with us now?

Much like the failures themselves, any negativity towards the new tundras (real, perceived or otherwise) hasn’t really been a thing on this forum for about a year other than you and 1 or 2 others staining this forum with your chronic vaginitis on the matter.
The reality is that the “negativity” towards 3rd gen’s was 50-100 posters holding reservations regarding the first model year of a complete redesign with maybe 1-2 Tommy Toughasses saying “I told ya so” after things started to spin out. That’s it.

*Let’s ignore the misapplied name calling as it suggests that us poor 2nd gen guys are rooting for our own motors to fail - because other than it being silly, we know what you mean. I’m sure you’re a great dude so focus on that instead of these nonexistent cheerleaders.

As for the OP, go pick a color and trim you like. Outside of the pro, things are probably back to MSRP or less if you’re willing to hunt/travel/wait. Rates are garbage so in that regard I hope you have cash. Test drive it, and reach out to the forum post that can get you a good deal on the extended platinum warranty. And enjoy the hell out of the truck. It’s a Toyota and they’re awesome.

 

No. We don't have to shop for extended warranty urgently right now, because there's yet another thing found that Toyota screwed up in this new truck. We cook dinner for our families.

 

And serve delightful "pie are squared round" for dessert!

 

This is an area not nearly explored enough on this forum.

 

I endeavor to plumb those depths thoroughly. And I mean that of all pies; hair or otherwise.

 

This is the way.

 

iMO, majority of new Tundra buyers/owners most likely never search for or join this forum if everything on their vehicle works as expected. UNTIL an issue arises and they do an internet search and stumble across our little community here. An issue could be something as simple as a squeak or rattle or something serious as a catastrophic engine failure. To me that would kind of invalidate the overall failure rate percentage based on just this forum membership numbers.

 

Fair enough. But, there’s equally as many that have failures and never check forums.
It’s a fair snapshot.

 

Exactly. You have to remember a lot of people in here, and elsewhere have no first hand knowledge of the over all gross sales failures rate. They speculate from stuff dredged out of the internet comment sections. For reference my 2022 hasn't had one of the failures people post. Knobs falling off, wind noise, etc. I have had 2 recalls which were solved, and a gas door problem that was solved.

Buy one, I didn't even hesitate, and would buy another tomorrow if this one got totalled . Get extended warranty and your set for 7 years bumper to bumper. If you end up with a lemon, sell it, its not like its your child and you're stuck with it.

 

I have always been a Chevy guy,but reading up on them brought me to look at Toyota,It was a tuff decision cutting the cord but so far I've been pretty fortunate with this truck and couldn't be more pleased with my choice.

 

Maybe... Maybe not... who knows, only Toyota's engineers and bean counters know real time numbers. Statistically if a person has no issues and likes product, they'll tell maybe one other person they like said product. If they're dissatisfied, they'll tell 10 people about it.

 

^^ Or get on the internet and tell the whole world...^^

 

A single match can set a field on fire,most people love to watch and join in on a good fire.
Taking the high road is tuff path to continue on and also refrain from tossing a rock or two.

 

And throw in countless conjecture on how and why the fire started...

 

That completely depends on what the problem was, how obvious it was to them, and how simple or complex the solution turned out to be. What makes you state with 100% certainty that Toyota did not know the cause a year ago?

 

Lack of transmission coolers.

 

What did they figure out?

 

Katekebo,

My experience in statistics is quite old, more than 40 years, but one thing that seems to be missing in your analysis is operating hours. In my experience with electronics, the key reliability metric is mean time between failure normally expressed in hours of operation. So it’s not the number of failures, it’s the number of operating hours accumulated between failures. It takes a lot of operating hours to get confident in the failure rate. When you look at cars and trucks operating hours are not normally measured most people would view it in terms of miles since we can all relate to that.

A quick and crude analysis looking at members who have reported failures, if we assume the 4500 Gen 3 trucks have driven an average of 5000 miles each, then the mean mileage between failures is 500,000. I have no confidence in that number because there are not enough failures to establish anything of use and vehicles need to accumulate a lot more miles on average to get a reasonable answer.

I am not an engineer but I interpret your methodology as what would happen in product engineering where you are trying establish that the reliability of the product is at least greater than a given design specification, meaning early failures with limited operating time send you back to the drawing board.

Can you explain?
To me Process issue - means people are doing what they were instructed to do correctly, but there is an issue with the method (process) that they are using and following. The process needs to change.
People issue - the people are having a problem executing the method (process) they were instructed to use. The process again needs to change if people will continue to be involved and not i.e. AI, robots.

 

So, people in Japan and Alabama doing the same mistakes?

 

Ok Riddler..

How can it be a People issue if failures occurred in engines assembled in different plants?


Lol I just saw vtl post exactly same question right now

 

Freeze frame is what it is: a freeze frame. Knocking engine has no freeze frames, because it has no failures from ECM point of view. If it seizes up abruptly and stalls at speed only then it would have one.

 

Meth?

 

Marcus Lemonis? Lol

 

More like calling Asahi "a beer", but whatever.
