Turbo issue

Yeah, looking at that repair sheet online you are correct. Hopefully more people respond to that poll about which side was replaced.

 

I’m sure there’s two part numbers. I don’t think it could be the same, it has to mirror so the layout would be different I would assume.

 

I thought Mike Sweers said that everything on the truck is redone and brand new. They took the motor concept from the Lexus but redid everything to fit the tundra.

 

And they are expected to use a turbo 4 banger. Good luck with that.

 

Mike sweers.. he tends to drive things right into the ground(look at removing the trans cooler on the later model tundras... look at the turd gen tacoma)
Anything he touches turns to pure crap.

 

Typically, the driver's side is more likely to run hot. The brakes, steering column, steering gear and on many trucks, most of the front diff is all on the driver's side.

 

Including this?

 

Yeah, it’s hard to see how Sweers still has a job. What has he ever done that was worth a damn?

 

How do you all know it was cheapened from the Lexus engine? The turbo is probably cheaper because of the sales volume of the turbo (120k Tundras vs 3-5k LS). If anything it seems they took the LS motor and modified it to improve it like the intercooler, adding the mechanical fan, and retuning it for higher torque.

 

What is the basis for this? "cheaped out on a number of parts." Here say, speculation or direct knowledge on the engine build and differences?

All manufacturers at times will run into quality issues and bad batches. We all know Toyota built a reputation on TQM-Total Quality Management. Perhaps I would have a different opinion if it was my new Tundra and they failed to correct. That said, I did experience a major failure with my 17 4Runner TRD Pro with the brakes. All tried and proven components and built in Japan. Toyota made good on it. Took a few weeks as they were baffled as well on Root Causing the issue. I've also been through and negotiated a successful Lemon issue-buy back with another Auto manufacturer receiving a nice upgrade in the end. Details held due to NDA. In both cases and my experience, patience is a virtue when expecting positive outcomes vs. Ready Fire syndrome.

 

That Gen 3 Taco would’ve been far better off w their I4 turbocharged... than w the gutless zinger 3.5 they dropped in it that produces literally ALL of its power/“torque” at 4500 rpm.

You do know a turbocharger is artificial displacement? And the Ford Ranger with the turbo I4 has far more torque(like 310 ft/lb, which is what a truck needs)than the Tacoma.
Additionally, you can purchase flashes, bolt ons from Ford to bump that “4 banger” over 300hp.
Seen the turbo 4s GM is offering in there Silverado’s and Sierras??

 

He didn't design the 3rd Gen tacoma, he was chief engineer over Tacoma since 2012 but Kevin Hunter designed the 3rd Gen Tacoma.

He also has been the chief engineer over the Tundra since 2010...I guess all Tundra's after 2010 are pure crap?

 

Not defending him one way or another, but he has been the chief engineer on the Tundra since 2010...So I guess all Tundras after 2010 are crappy Mike Sweers engineered vehicles.

He as the Chief Engineer over Tacoma since 2012, but he did not design the Tacoma.

 

What drove this? Maybe Lexus owners throwing a hissy fit when they figured out Toyota owners were getting Lexus quality for Toyota prices or they were getting Toyota parts at Lexus prices?

 

Hahahahaha really? That is your defence?
The design of the 3rd gen is great, the engineering is dog shit.

And the tundra didn't fundamentally change so he didn't do much with it and what did change has his name on it: Transmission cooler.

 

Lexus engines are made primarily in Japan...It is quite probable that they use different suppliers for different parts on the engines depending on regional supply.

Which also helps to explain why different grades of fasteners etc are on the Lexus and Land Cruiser engines even when using the same basic engine that are made for US trucks (Tundra).

Almost all of Toyotas best most reliable over built models are the models made in Japan. 4runner/Land Cruiser/Lexus

 

I am not defending anything, I just wanted to point out that he has been around different models for quite a while. The Tacoma transmission cooler also was changed in late 2020

 

Bought my wife a 2020 Corolla hatchback, when I was installing Toyota OEM accessories, I realized that the entire car is made in Japan. Made me happy.

I used to have a 2016 GTI, made in Mexico. The same year Golf R is made in Germany.
According to the Mk7 community, anecdotally at least, the German made Golf R seemed to have far fewer problems. My GTI had quite a few problems. Heck, CEL illuminated right after I bought it, brand new. Also blew the DSG and it needed the entire sunroof assembly replaced too.

 

And here, same guy, telling you same engine same components, etc that it is built different in the LC /Lexus than Sequoia/Tundra

Yes exactly!

People what you need to understand is a turbo is an incredibly complex device that is made up of thousands, I mean hundreds, I mean a few dozen parts....yes it could be any one of those few dozen parts! Toyota is working on it, be patient!

Oh wait, it's only the wastegate sticking open or closed. Ok people, you need to understand that the wastegate is is an incredibly complex device consisting of.... oh wait 13 parts.... yes it could be anyone of those parts! Toyota is working on it, be patient!

Oh wait, it's only the wastegate actuator. Ok people, you need to understand that servo actuator is an incredibly complex piece of engineering consisting of....oh wait, I forgot maybe its the software! Yes, what you people need to understand that wastegate control software is really complex! Toyota is working on it, be patient!

Lets not also not forget this is Toyota we are talking about, it's not like they might actually have that many engineers who could be made available to look at this.

Lastly, rest assured this was only a handful of cars. Those customers taking delivery of recently built trucks are not experiencing the issue.

Again rest assured Toyota is working on it, be patient!

 

You’re making light of a complex situation. Manufacturing is difficult and there is a lot involved.

 

One thing that is not complex in manufacturing is that if a issue comes up with a purchased product, you take care of the customer that purchased the product by supplying parts immediately, even if that means you cannot produce any new product. That either seems to not be the case with Toyota, or they are continuing to knowingly produce vehicles with bad parts.

I did see a post earlier today from someone that works in the engine plant for the tundra that said they know they got a bad batch of parts and they have narrowed it down to effect 500-1000 vehicles.

There are 1200 Toyota dealers in the US, so I think the less than 1 percent of trucks with issue is a little bit low.

 

People compare the LC of that generation to the Tundra since it is the same platform, just like they do with the Lexus now saying engine is not new etc. The Lexus is also built in Japan like the Land Cruiser, You can't really apples to apples compare like people are doing since they are apparently different even with the same engine... I guess it still comes down to you get what you pay for with build quality since both the Lexus and LC are more expensive.

I still think the 4 runner is their best built affordable model...it should be though, in the rest of the world it wears the land cruiser name.

 

Exactly! What you people need to understand is that Toyota is doing everything in their power to make this right. They are continuing to keep their affected customers clearly informed, putting those people at the front of the line for replacement parts and extending warranties. They have isolated the problem to a specific small batch of defective parts. That batch has been isolated and is definitely not still going into new builds. All recent builds are not experiencing this problem and therefore customers should rest assured that there is absolutely nothing defective with motors being built today. Toyota has bit the bullet and issued a Mea Culpa recall of the VIN's affected. As part of the recall they are recognizing the good faith of those early full MSRP +++ purchasers with loaner trucks while scheduling theirs for service.

 

Corporate Toyota: aw man vehicles are getting really complicated, what can we do?

Toyota employees: outsource!

Toyota customer: I am going to keep buying Toyota because they are reliable vehicles

-vehicle is broken right after buying-

Toyota customer: waaahhhhh TF?

Toyota customer service: it wasn't us, it was a supplier issue

Toyota fans: ah man they're gonna fix it, besides it was the suppliers fault!

Customers having epiphany: oh, so it's not really a Toyota anymore.....

 

Just a direct observation. I've had my hands all over both my 17 4Runner TRD Pro and my Roush RS3 Mustang. The mustang is pulled from the Flat Rock Michigan facility to the Roush facility and reworked and upgraded with Roush components. That said, Quality is night and Day difference. The 4 Runner is a 4 wheel tank extremely well designed and thought out including fit and finish. Very simple to work on it from all sides. The Roush/Ford in comparison Designed to work on it is a bear without virtually any ease of access). The finish in terms wires, tubes and clips-- night and day difference. Understanding Toyota's quality process and comparing to Ford ......... not in same league. What the Roush does have is fantastic handling, lightening speed, solid interior comfort and a great sound system. The cockpit is well laid out and its fun to drive. To me, its choices and priorities. I wanted the Roush for those qualities and the Tundra for my daily and trips. Yes enjoy turning wretches on my cars so to me the difference is moot.
All that said, I'm confident in Toyota and there products

 

The same way BMW improved the McLaren F1 S-70 V-12 when they put it on the 850 and 750. Minor differences in Horsepower, but really mostly same engine with minor improvements....

Sorry feeling very cheeky today. In all seriousness, it looks like they share the same block and certainly engineering knowledge, but that's about it.

 

Would be interesting to run a survey finding out from people responding to this thread actually have a new Tundra with the issue. Would help to understand numbers in clearer light.

 

Which post is that? I saw a guy from the engine plant say they missed the bad batch of turbos or something to that effect. It would be the turbo suppliers job to QC their parts.

I think the biggest issue is the disconnect in the modern automotive industry. There are many levels of separation.

The internal structures of automotive companies are so complex and often divisions are highly separated (sales, marketing, service, parts, R&D, etc). Then you have distributors which are not Toyota (such as Gulf States Toyota which is owned by the Friedkin Group) followed by dealers which are also not Toyota. So the dealer is still learning how to deal with this vehicle and there’s a supply shortage. I think Toyota would readily give good parts directly from the supplier or engine plan but who makes that call? You need the dealer to fight for the customer with the service reps who in turn need to talk to Toyota sales division, parts division, R&D division, the engine plant, the supplier plant, etc. I’m sure the dealer techs and service writers are looking up parts, seeing long lead time, and relaying the lead time to customers without thinking to escalate the issue. I’m sure the parts are there.

Here’s the surprise bit, every company that manufactures complex product has suppliers.

 

What? Please prove any shred of that with factory tolerances, spec sheets, etc, Anything beyond mere armchair speculation.

Oh wait, just noticed you drive a Gen 2, carry on. *hate noted*..
