Blown engine

Couldn’t it just be a bad supply of bearings

 

There are typically like 4 or 5 tolerance buckets in the engine. I would not be surprised if it ends up in finding some d**khead at the assembly line doing subpar job in using the wrong tolerance parts, because who cares?

 

That first oil change the oil drained out like water. Wonder if this motor should really be on 0w20.
Take a look at the raptor v6. 5w30 is the standard and 0w30 is for exteme environments.

 

First post from OP “engine failure”… prove it or it didn’t happen.

 

The 3.5 Ford max torque hits at 3000 rpm. The Toyota is around 2000. The oil pressure I notice is very low around 1700 RPM. It holds 10th gear even going into 40 mph winds. Very impressive. I don’t think the Ford will hold gears like that - at least ones I’ve ridden in they don’t lug like that. To me that’s the difference between the 2, the Toyota will lug, it’s more of a stroker engine with a lower torque curve = much more stress on those bearings.
Also look at Amsoils testing - they show pics of main bearings with conventional oil after 100k miles - they are toast. That’s why I think it’s the oil quality. This engine will be harder on bearings due to the torque curve vs the Ford the way I see it. And the testing Amsoil did proves that’s even a weak point in the Ford with low quality oil - it’ll only be worse in the Toyota engine.

Toyota is talking to the owners of vehicles with failed engines. As of yet, we cannot determine a specific pattern that can help us identify why these have failed. The total number of failed engines is under 50, which makes it a 0.0003% failure rate. Not high enough for doomsday like some of the members here are calling for, but still nothing we're ignoring.

We've got a whole team trying to track down the root cause of these failures, and as soon as I know information that I'm allowed to share, I will let y'all know.

 

under 50 suspected bearing failures. I believe the turbo failure numbers are similar, but the ticket for that is with a different team so I don't have details.

 

Thank you for your post. I don't expect perfection but I do look for how companies respond. With both the Turbo and this bearing issue, Toyota is not hiding from the issue. As near as I can tell, they are taking the proper steps to take car of the customer and remediate the problem.

It's hard not to compare and contrast to a nightmare I'm in the middle of with a new F150 that has electronic gremlins. 7th consecutive week in the shop and it simply can't be repaired. Ford is unresponsive on the buyback claim and I've got a $70K doorstop. For what I do, the F150 has a better feature set but their response to a problem is so far off the mark it's ridiculous.

Knowing that Toyota is making solid efforts to deal with a problem makes it easy to switch to a Tundra.

 

As a serious question and not being a provocateur, is there any concern that a lot of these failures seem to be happening with as many as 45k miles on the trucks? I guess point being, there may be less than 50 at this moment but is there concern that the number could climb exponentially as more trucks are approaching that mileage range? Just going off that statistic that the average driver in the US drove 12,700 miles in 2022.

 

I had so many issues with my 2021 Bronco and 2 different Ford dealerships basically tell me to go fuck myself. Tried escalating to Ford and they told me to go to a dealership that was 2 hours away. Ended up just selling the Bronco and getting my Tundra. I think Ford may be one of the worst customer experiences I've ever had.

 

Definitely a concern, especially since the failures appear to be random. Luckily, Toyota has processes in place for stuff like this and we'll do our best to take care of our customers

 

Well, at least I'm not alone. My F150 has gone from swapping telematics, APIM and gateway modules. The new ones don't talk to the old ones. The only electronics tech quit to go to another dealer. Nothing short of shocking.
I don't own a Tundra yet but thanks for standing in there and not being invisible.

 

They’ve already made 1M new tundras?? If not, your stat is BS.

 

Toyota sells 100k or less Tundras a year. Much less figures for Sequoia, Lexus and TLC.

 

1,000,000 * .000003 = what?

 

How many units sold?

160,000 x .0003 = 48 for example.

 

Expect .0003% makes the equation 160,000 x .00003 = .48 in other words half of one engine failure. We’ve got a few more than that documented.

@Silver17 ’s equation would be for a .03% failure rate.

 

Yep - I’m the one not good at math. How would you calculate 10% of 1,000,000?

1,000,000 x 10?

 

This might help if you struggle with math

@ryanwgregg

 

Allow me to present it another way.

48 failures \ 160,000 units sold = .0003 (not in a percentage) of the 160,000 units had a failure.

To @AZBoatHauler credit
I will say, saying .0003 In a percentage is technically .0003 x 100 = .03%.

 

Exactly.
Kind of a big deal if the problem is 100x worse than the BS stats being spewed…

 

In before the “new math” peeps argue that a .03% fail rate isn’t 100x worse that a .0003% fail rate.

 

So you’re standing by this then?

that’s the worst “I’m sorry I screwed the math up and was wrong” post I’ve ever seen.

 

Still very tiny numbers. And for those that seem to be hung up on all this, remember the 100 x zero is still zero. And 100 x "close to zero" is still close to zero.

 

I’ll concede some effort but you still say 100,000 * .0003% is 30 when in reality it = .3

Still comical you say I’m bad at math then demonstrate you don’t understand percentages but can’t win ‘em all.

 

Them damn engine bearings!! They bearing down on us!

 

Maybe its a combination. 0W-20 combined with 10k OCI's in an engine designed for work.

One of the mistakes Ford made when designing the Ecoboost was that they assumed people were going to use them like trucks(at least thats how it appears). They designed the original 2011-2012 trucks to be worked, and they were designed really well TBH. The original intercoolers were fantastic. A lot of the early problems the Ecoboosts had could easily be attributed to the trucks not getting worked combined with longer OCI's. Their fixes to the problems the trucks had all dumbed the trucks down. They put plastic plates into the intercoolers to make them less efficient with more pressure drop, they had to change the tuning to run leaner at idle to keep fuel from building up in the oil, PCV changes, among other things.

One thing Ford did early in the Ecoboost life was switch them from 5W-20 to 5W-30. This happened prior to the F150 getting the Ecoboost, but it was the same 3.5L but in the Flex/Taurus SHO/Explorer. My guess was this was to combat fuel dilution inherent in DI motors.

 

If I was to again dare and attempt math in this thread, I might say it was 1 in 3,300 trucks…. At the moment anyway.
