Turbo issue

There isn't a lot of pics, there's a few in the pages above, your pic is pretty good. It's a cramped engine bay, I think it isn't a horrible caboff job. Accessible through the wheelwell but the tech has to disconnect the exhaust pipe to get the wastegate subassembly out. Not a take the day off kinda thing for a tech that has it scheduled.

 

From what I have read, the long / no crank issue seemed to have been a software issue that has been resolved.

 

That post was from a month ago. Pretty sure software he is talking about the grill shutters and parking brake not wastegate. ( see below from this week) Don’t think he was mentioning a software fix for turbo issue, but could’ve missed it.

He was talking this past weekend about turbos though. Hyper defensive. Talked about bench testing them to no avail, that they can’t test trucks for it before they leave the factory, they won’t halt production since they really don’t know the cause and finally fear not, because they are working really really hard under terrible circumstances that we can’t understand to figure it out.

 

Sounds like a hardware issue now based on those comments. Out of spec wastegate and not actuator?

 

It seems random or unknown. An out of spec wastegate would have been easy to troubleshoot, isolate, and fix.

 

Well, it was mentioned that the Tundra turbos are Chinese, and knowing Lexus, those turbos probably are not Chinese. I think y'all are catching what I'm saying....

 

Someone posted pictures of both units one from Lexus and one from Toyota for and they look to be arranged differently. Likely not drop in interchangeable.

Fan boys need to stop posting that they’re the same engine as the Lexus. That’s like saying the McLaren F1 V12 engine ended up in v12 BMWs. Similar in many ways, shared heritage, but those claiming it’s same engine have no clue.

 

I wonder if they are troubleshooting/testing these turbos under full heat load.

 

And they are $3000! Instead of $550 a piece like the Ecoboost.

 

They seem to have figured it out. I am on the Duramax facebook group and I don't see anyone saying its not, they all seem to be happy with the fix.

It never was a huge deal anyways. The trucks never wouldn't start, it just might take a try or two. It's not like people were stranded because of it.

 

Ive owned 6 Toyotas in the last 15 years. One tacoma, 3 4Runners, 2013 FJ Cruiser 6Speed (still own it @ 125k mi), and 3 Tundras. 2010 4.6, 2014 5.7 CrewMax SR5, and 2014 5.7 Double Cab Limited. All were great vehicles. I now own a 2021 GMC Sierra 1500 w/ 3.0L Duramax diesel. The power delivery is substantially better at altitude (8500'+) compared to the 5.7 V8. The towing performance is superior too. The 10-speed auto is smooth as silk.

My truck has about 6k miles on it and during the first few months I had 3 incidents of the start failure. I'd press the start button and it would turn over for ~5 sec and stop. Id press again and it would start. Never stranded. I have not experienced this issue in the last 6 months, and I never took it to the dealer for repair. Im averaging 20MPG w/ 3.5" lift and 34" studded tires in the winter. When I bought it last spring, I was seeing around 23MPG average. My 2014 tundra 5.7 on 35" tires averaged 13.4MPG over the 5 years I owned it.

I am now considering the 2022 Tundra Double Cab, but the turbo issues (and other issues) plus the double cab getting smaller has me thinking twice. I need a 6.5' bed, and the 22 crewmax w/ 6.6' bed is too long. Id like to get back into a Toyota for the off-road capabilities, but the new cab configurations are missing the mark for me. I did drive a 22 Tundra DC TRD and the 3.4L turbo is a welcome performance improvement (at altitude).

 

Yeah, my living room is at 6500' and I tow a travel trailer. I won't touch anything that doesn't have a turbo in the 1/2 ton class. I'd rather a 2.7 Ecoboost or 2.7L turbo GM motor(now that its getting bumper 420 ft-lbs especially) than any of the V8's honestly.

The Tundra 3.4, 3.5 Ecoboost and 3.0 Duramax are all on my list. My neighbor has a 3.0 Duramax and tows a trailer similar to mine and I think he really likes it. He came from a 2014 F150 Ecoboost max-tow that was nearly identical to mine so he's a good person to ask lol.

The 2022.5 3.0 Dmax is going to have the optional max tow package now with 3.73's, upgraded cooling and uprated GVWR.

 

Y'all talking about the Duramax diesel aren't put off by the ridiculous diesel fuel costs, DPF and other typical emissions reliability issues all modern diesels seem to suffer from?

 

Engineering to Cost Accounting: Run your cost models to determine the cost impact of substituting this part A for this part B.

Cost Accounting to Engineering: Here are the results.

Engineering: OK, we're going to use part B.

Fucking Bean Counters, lol.

Such great memories. I always get a kick out of people that think the "Bean Counters" make these design decisions.

 

So you are telling me:

Miles of accumulation on Part A - verified - released for production.

Different vendor comes in and supplies Part B for testing, costs less than A but told "it's a better part".

Meantime vehicle is released to start production.

All while parts are being sourced, tooling getting set, etc on the assembly line - Part B gets tested, found to pass / verified and it is released for production...

You are telling me a "bean counters" have no influence to this decision?

Auto manufacturers are in the game to sell a lot of cars, and make money doing do. If a part can cost less AND provide the same "reliability", the beans been counted.

This isnt a "design decision". This is a mechanical part that has X cost over the production if 500k (ambiguous #) units. If Part B costs less than A while "shows the same or better reliability" - Part B will be the winner.

 

No spec for heated up turbo maybe?? That’s a tough one, what do you do, run hot gasses through the turbine to heat up the turbine?

 

The turbos work though.

Also, diesel here in Utah is about the same price as 91 I believe, although I have not looked in a while. And 91 for me is only 14 cents more than 88 octane, which is only 14 cents more than 85 octane. Since you can't run 85 in these trucks or the Ecoboost trucks, im running at least 88 or 91, both of which are very close to the price of diesel.

I used to have a Jeep Liberty CRD until late 2019, so I was more in tune with prices and diesel had been the same or even slightly less than 91 here.

 

If project managers and engineers responsible for staying on budget and making purchase decisions are bean counters then I agree.

 

@Lowcountry4x4 my recommendation would be to take delivery of the vehicle if you like it and purchase a 10 year platinum Toyota warranty which are just around $1550. If this price makes a huge difference or would make you look at other vehicles in that $1550 higher price range, then go with that other vehicle. Toyota's history of reliability allows for an amazing warranty for a very long time at a very low price which negates the impact of the issue (aside from potential resale value problems). So just all things to consider as you make the final decision.

 

Here in WA state, diesel is at least $1.00/gal more expensive.

Personally, I haven't owned a diesel, but I've been assigned diesel trucks at my work. I don't like DEF, but I don't pay for it. And every CEL has been related to emissions components, and I have heard that's expensive. My friend has a RAM Cummins 3500 and he said it's very expensive to maintain, but he has an extended warranty for it

Not trying to bash on diesel, I am super interested in the GM I6 diesel, very cool design and I've heard it drives excellent. However, I've also heard that every modern diesel is extremely expensive to maintain off-warranty, mostly due to required complex emissions equipment.

 

Nothing tough about it. Done everyday. However the engineer posting was saying they were only “bench testing” the failed units and seeing no issues . This was leaving them perplexed. Soley bench testing is not a real world test. Not even close.

Hopefully, he is wrong and they are doing a lot of this:

Would it be odd for dealers to already have 187 used 2022’s on their lots?

 

Cool video, amazing how hot the exhaust was 4 feet from the turbo.

 

Wow- finally!!! Took them long enough.

 

Ha.........ha.......... Real funny

 

ya, nice fools

mike beers, lol

 

Sunday FB check in.
No super low milers this week 1,100 to 11,5000 miles.

Maybe March builds aren’t having the issue?

Maybe the earlier build aren’t out of the woods after 1,000 miles?

 

Those first two pics are basically the same mileage, coinkydinks or not?

 

Different person posting. First 3 are all actually right around 1500 miles. That one at 11K is no bueno if it turns out to be turbo. Some with that message get a new turbo and some don’t .

 

The later failures would be more concerning. That's why I've frequently mentioned Toyota should extend the warranty for the affected date of manufacture range.
