5:37 “We’re always trying to keep the cost on these trucks down.” It’s a good thing they saved money on not having an engine cover. Otherwise, they wouldn’t have been able to keep the TRD Pro to the low price of $65K.
saving you money on 10k oil changes, lol! Sheldon's job is to build trucks....
@@tslicker1990Technically they are 5k miles under certain conditions. 0w20 oil is abundant and low cost. Oil changes are easy DIY on these.
Why didn't he ask why the price didnt decrease?
He said they trying keep the cost for Toyota not for the customers 😄
@@arashefi Wrong. Groceries have tripled. Cars have only gone up 50%.
10,000 mile oil changes are nuts. I don’t care what Sheldon says. Use a quality synthetic oil and change it every 5,000 miles on the dot. Maybe even every 4,000 miles if you do a lot of city driving.
Right ! If you keep a car 5 years or less that’s ok. But like me 10+ years, 5000 miles of synthetic oil is the most. Turbos burn that oil much faster.
7500
I think Sheldon is full of it.
How else are they gonna get you to come in a buy a new truck?
You are absolutely correct. We have had turbo cars since 1986 and have hundreds of thousand miles without any engine work whatsoever. Mostly the turbos were only oil cooled with no water cooling. We changed the synthetic oil religiously at 4000 miles. Never had a turbo or internal engine problem.
I was not even thinking about buying a new 24 trd off road premium 4 runner when the opportunity came about to do so, so thankful i did buy it!! Shouldn't have to buy another vehicle in my lifetime!!!
And how many of you guys, keep a car for 200,000+ miles? I do, and I have all my life. All I read is guys complaining about the price. And these very same guy's, turn around and say, "I am going to keep my 2022, 2021, 2000 Tacoma." You very well should KEEP IT. It's a NEW Truck. You don't NEED a replacement for it. You should Thank God everyday, that you could afford a new truck. Also, they have been using Turbos for many years now. It's proven technology. I can remember people in the "old days," complaining about those "new fuel injection systems." They would said, I am never going buy one of those "new" fuel injected engines. I will stay with cars, that only use a carburetor. Try This.....They used to use a horse for transportation. No tech and all you need to do, is just feed it.
Amen enough said!
Very well said.
Have you seen the price of oats lately? 🐎
It’s because they are trying to convince themselves their purchase is not with regret. These same folks will quietly trade in their nearly new reliable “old” Toyota and buy the new reliable Toyota to keep up with the Jones. That’s why Toyota makes a lot of money! lol
I have no fear of the new 4 bangers in the 4Runner or Taco, but I will still keep my '21 4Runnner. I am like you, I drive until it NEEDS replacing beyond what the normal maintenance supports in life span.
I am sure the new powerplants will be just fine and reliable, though time will tell.
Time will tell. I’ve got a ‘21 4Runner so thankfully, I’ve got plenty of time. Hopefully in 15-20 years I’ll be able to get another vehicle that proves to be just as reliable.
Ur better keeping that 4Runner and keeping up the maintenance with that…
The engine in the 5th Gen 4R is all aluminum with liners, four cams, dual VVT, and 24 valves. Many said it would never last compared to the cast iron pushrod V8s. They were proved wrong. That being said the newer turbo engines will be less reliable initially, but get better over time, just like the 4.0. Eventually the turbo engines will be more reliable than the 4.0.
Adding more parts, especially a turbo and the additional parts needed for that, adds more moving pieces, as well as adds to the complexity. More shit that can break and a very expensive fix
It’s not simply the durability factor, it’s the cost of ownership factor that’s concerning. I can do a ton of work on my current vehicles, one of which is a Toyota truck with over 200k, and that saves me time and money. The complexity of this powertrain limits what vehicle owners will be able to do, and that adds expenses, especially for those who have to buy used due to the ridiculous costs of these new vehicles.
Right on. My 2008 4runner has 312k and runs perfectly. I do all my own maintenance. Nothing major, but I'll put in a rebuilt transmission or swap a motor if I ever need to. Doing those still beats the cost of a new one by a wide margin.
We've had four 4Runners. The first three each gave us over 350k miles worth of running life before we traded. This last one, a 2000 LTD, blew the #3 spark plug right out of the head, but that was at 328k miles. Say what you will, Toyota makes a quality product. Does that mean I want a Turbo? Hell no. I'll stick with my NA engine thank you. If it ain't broke, don't fix it. NA works just fine.
New gen Tacoma truck sales down 50% from same quarter last year. The market doesn’t like the turbo four only option!
That and the huge price coupled with higher interest rate isn’t helping
Nice Interview. I've seen a lot of Sheldon Brown chats, but this one w/ DC brings more light to the table. I appreciate that and it's good to see the passion of both individuals.
Toyota needs to produce a 4x4, one ton, 8’ bed, diesel pickup…with a stick.
I can't get enough of Sheldon's content. I've watched him on several channels. He is just incredible. As a fellow engineer (systems/electrical) I would love to just sit down and chat with him for hours.
He's full of lies and has been proven in the tundra and tacomas.
@@Mineisbigger gonna need more information than that.
Talk is cheap. Like the tundra, let’s see how real world driving correlates with all this superior engineering!
Wow! Excellent interview with the Toyota Engineer!
Thanks for the video David
Thanks, David! I appreciate these informative videos. Hopefully, they'll be as reliable as the previous gens. 🤞
I will NEVER buy a Tacoma with a 4 banger turbo, or a Tundra with a 6 banger turbo…NEVER! Toyota has made a mistake. Proof in point, the Frontier is out selling the Tacoma. Tacoma sales as well as Tundra sales have plummeted and they’ve suffered a large quarter loss.
Amen 🙏
I don't have a problem with all the new tech. I do however have a problem with not having the choice to get a naturally aspirated V6 or V8. Their is obviously still a market for both so it only makes sense to cater to as many people as possible. Just another example of the goverment and manufacturers forcing things down our throat. Definitely will be keeping my 2021 4 runner for the next 15-20 years. Only time will tell... I'm not convinced
You say you don’t have a problem with new technology, but you clearly do. Don’t lie to yourself! You do you bro.
@@brucemoose2 What does wanting to have a choice have to do with new technology? So you like things forced on you? What am I missing here?
@@cmk2675he probably still wears a mask
@@janetairlines1351😂
The reason you don’t have the choice to buy a v6 or v8 is due to government regulations, emissions and mileage, that are designed to force the adoption of EV’s. So if you want the marketplace to decide what vehicles should be offered for sale, rather than the government, you need to vote Republican. Democrats want to end cars as we know them. As part of a massive plan to increase population densities, increase mass transit and reduce single home ownership. Government policies are distorting the marketplace.
Thanks
Very enlightening. Currently waiting for manual, good info to make the wait worth it
This was excellent. Thank you.
This is a great interview! Great job David!
"Keep cost down"?? Have you seen the starting price for the Tacoma?!? It's INSANE!
David, It is always helpful to hear the perspective of those on the inside. 😁 With the bare frame and drivetrain components exposed, I would have been tempted to ask why Toyota's locking front differential is not available on any 4X4 in our market. 🤔
Amazing interview!
Great interview. Sheldon is very knowledgeable. Thanks David.
Hope we can get some more information on the Landcruiser FJ soon.
I decided to keep my 430k 2001 Tacoma and spend money on maintenance over a new one. Because I trust it.
Keep the cost down 😂 no engine cover! The old V6 always have a engine cover
Would be nice to cover up the that alien nest. ugh. Hard Pass. V6 please!
David, Extremely awesome interview with Sheldon Brown.
I learned so much from your discussion.
That guy is full of hot air and it ain’t from the turbo.
The Bots are strong. Hard pass on the TURDbo...
Excellent interview very good questions, funny you always had one more question like “Columbo” 😅
David I would love for you to take us on a tour to the Guanajuato and Baja California Production Plants for the Tacoma. I need to see why I would overspend on the new Tacoma.
I hope the tour includes a look at the workers' pay checks. We need to settle the debate of whether wages have gone above $3 per hour.
Awesome interview!
Great information! Thank you I like seeing this before I make a big investment in a vehicle .
Thanks Sheldon👍🏼
Going straight to the source, excellent interview, excellent information. I have never doubted Toyota or Lexus, I bought 2 in the last year and am 100 percent satisfied. Well done, David, thank you. I will still let my turbo LX idle for a minute and cool, and I did break in oil change at 500 miles, and I will continue to change at 4k mile intervals for the rest of my life. Now, if we can stop blaming Toyota for inflation, we can enjoy the best vehicles produced on the planet that are used all over the planet. As the man said, "So far, it's undefeated."
Great interview
Great video!
Bots.
Watching this and getting a better idea about all the science and engineering and overall complexity for something like this, should make everyone understand why they don’t offer all of the 500 different options/varieties people seem to want on here. Great video David, thanks as always.
As a general rule, ALWAYS follow the severe duty schedule for your car maintenance
100%. Regular schedule is for lower cost to own and CAFE hurdles the manufacturers are trying to abide by
Always love these interviews you have with Toyota engineers. Interesting what they have to say technically about why things were done a certain way.

@@scholz222 How do extended maintenance intervals play into CAFE? Actually curious.
Modern oil is very good and keeps getting better. At some point you are just throwing away money. Usually corrosion, worn suspension, and failing electronics is what totals an old car not the powertrain. That being said if you take a lot of short trips going 10k miles is pushing it.
The four cylinder turbo 4 is a deal breaker.
2.4 turbo 4 cylinder has been used in Lexus NX for the past 5 years, but I haven’t seen one with 300K miles with the original turbo.
You probably never will
Good viedo 👍. I just bought the 2024 Toyota 4Runner SR5 premium. Beautiful truck, I am very happy with my truck.
I also have a 2009 Tacoma 4x4 5speed extended cab also a great truck thanks Toyota.
Sheldon LOVES his job and I’m thrilled about that
Bots bots bots...
Super knowledgeable guy
Tacoma sales down 60% with numerous recalls. nuff said!!!!!!!!
I’m stoked for the direction Toyota is headed
Interesting thanks for the details. Would like to hear what has been done to address the 4runner tailgate rust issues.
Please please please give North America the option of a 4.0 v6 base model lower cost Tacoma and 4Runner. Overseas even the 300 Series Land Cruiser is offered with a NA 4.0 v6.
That’s simple because those countries don’t have the emissions regulations that you can thank your government here for. It’s not a Toyota decision my friend and other manufacturers will follow soon to conform to 2027 emission standards. Have a great day
Just grab a 2024 4Runner. They are available at your local dealer now. Comes standard with your 4.0 v6 engine. Lots of people are opting for it because it’s the last year you can get that configuration. Super reliable, also.
@@bax737I agree. Got mine 2 days ago
To rub salt in our wounds, let us remind ourselves that 300 Series with the 1GR-FE can also be equipped with 3 locking differentials at a price of approximately $60,000.😉 The 250 Land Cruiser will also be equipped with the tried and true 2TR-FE 2.7 engine in some markets. 😁
America government regulation. They drive whatever they want YOU cant
I'm hoping the 250-series is a massive succes because maybe then Toyota can consider bringing the successor of the 300-series LC back to the US.
It was not as good a seller as its brother in a tuxedo the LX, i honestly think the LX just need an overtrail trim and thats it
No one bought them unfortunately, we all could have
With the Sequoia existing, there’s no way the LC300 will come to our shores anytime soon…
@BigAltimaEnergy719, unless the sequoia goes back to the independent suspension route like the previous gen, and if they sell enough to justify the cost of producing another suspension for family duties, along with putting enough modern touches and making the 300 (or 400 series) more off road oriented, then the land cruiser will now remain beneath the sequoia
@@BigAltimaEnergy719 sequoia is too big though power figures they are about the same only that lc300 is more compact and same time has more offroad features specially the lc300 gsr
So, let me get this straight. You increase price by 30%, design a motor with more issues that’s stressed more that will last half as long, just to get 2-4 mpg better. At $3.50 a gallon it would take you about 400,000 miles to make that initial cost back. Ridiculous. It’s like idiocracy these days. No one can think for themselves.
Nathan from TFL is now an engineer for Toyota. Nice
Good interview David! All, please buy those cars now and I will buy one of 4Runners in 10 or 15 years probably, when reviewers start to call current TNGA platform “outdated” and “ancient”.
I love my Solar Octane 2024 Toyota Tacoma; I love the way it looks, feels and drives. Unfortunately, I have been without my truck for 30 days now due to factory paint issues and system malfunction issues which require parts that are not currently available. The truck has 622 miles on it, with 300 of those from driving back and forth to the dealer. It currently sits at the dealer waiting for those parts. I have no idea when I will get it back. Not a very happy camper, especially since I paid almost $60K with all options. I hope Toyota can help expedite repairs as I would like to drive what I paid for.
I would really like to know what Toyota is doing about the ADD (automatic disconnecting differential system ) issue. There’s a part in the transmission that is designed to fail to prevent damage however, it is failing under less than rugged conditions. TFLoffroad did several videos about this on the 2024 Tacoma but assuming it affects multiple platforms.
Now with the Tundra recalls I'm wondering about this engine too, I know the platform is used in other vehicles, but the seeds of doubt have been sewn.
With hybrid both trd pro/trail hunter and LC how deep water crossing can they go???
Did they keep the D4S technology from the previous V6? If not what did they do to reduce carbon buildup associated with direct injection engines?
Yep they still have it! It’s talked about in another video, but I forget which channel, maybe TFL.
So will the turbo 4 also have a spun bearing issue?
But look at the all the problems now being seen on the new Toyota trucks. What do you say about these problems? Wastegates,main bearings, etc
Toyota says just buy one for $70k and experience it yourself! What a clown show for a Mexican car!
I have a 2022 V6 Taco. Maybe in 10 years or so after all the guinea pigs have experimented buying a turbo 4 banger I might rethink my prejudice. But for now, don't be surprised if I am still happy with what I have now. Good luck with that new tech.
David will it prolong the life of the turbo if you leave idle for 2 minutes before shutting the engine down?
He has said recently in another video you only need to do that if you are driving it hard and then immediately parking it
Toyota is one of the most conservative automaker in the world. Their hybrid system is proven to be reliable with minimal to no addition to maintenance cost. Turbocharged gasoline engines are pretty common, and most of the scary urban myth about their durability is resolved at least a decade ago. Yes, it would be comparatively less reliable than their V6 NA, simply due to having more parts, but considering the gas price these days, it is a fair trade. If you have to cry about new techs kicking in, just keep your ol' reliable, or go with the vehicle that offers traditional NA V6/V8.
Well, I am disappointed by interior and cargo spaces, and higher-than-inflation-rate price hike though.
What ever happened to that low introductory price ?
Where was this recorded? It looks like Riverside or San Diego counties.
This question is to automotive press. Can you get a Toyota designer to explain the tundra engine failures. For Toyota to get customer confidence they need to explain why the failures are happening and provide a a fool proof fix. I’ve heard of many new tundra’s requiring multiple engine rebuilds. That is not confidence inspiring. To build brand loyalty is difficult and long term reliability is needed. But to lose brand loyalty is easy with Toyotas ongoing recalls and failures.
If he talked about that he'd get cut off from official Toyota guys like Sheldon, and official Toyota events.
Please do a video specifically about main bearing failures in the V35A-FTS engines. Would like to know how Toyota plans to address this.
David, I noticed in the owners manual of the Tacoma, they recommend 87 octane, while the Land Cruiser the owners manual recommends 91 octane. I do believe the powertrains are exactly the same with the exact same power output on the Tacoma Hybrid and the Land Cruiser. Any idea why that is?
Tacoma and 4Runner are bread and butter of Toyota.
1. Toyota 4bangers is the best.
2.Toyota is the most experience on the hybrid for most 3 decades
3.Toyota has turbo engine for long time ago such as supra(straight six) and MR2 for decades back 90's and 2000's.
4. 1 but is that Tacoma is made in the U.S?
5. Vacuum is the only way for controlling waste gate turbo because it is response according to engine speed and vacuum in the intake manifold
I Trust Toyota period.
If these hold up through 2035, maybe I'll buy one. Until then, I'll be driving something NA. We buy Tacomas because they're reliable. These turbo engines are one big question mark. Good luck with sales Toyota. Can't help ya out this time.
I was a Ford truck owner for most of my adult life. I worked on them for a few years in the forestry industry, where durability was paramount. The f150 line stood up to the daily use very well for many years. I became discontent with all the manufacturers because of design flaws that were built into vehicles decade after decade. The more I spoke to and read what Toyota owners had to say about their trucks, the more I was convinced to buy a Toyota. I bought a low mileage 2013 4 Runner a few years ago and have never been happier with a vehicle. It does what it is supposed to do every day with nothing but normal preventive maintenance. The previous owner did NOT do any rust proofing , I rust proof it yearly and believe it is the most reliable vehicle I have ever owned. It may be the last SUV I will own because it will out live me. If I ever need a vehicle, I will always look at Toyota first, and likely no further.
Masters compete with each other，nice!
I just got a 2021 TRD 4x4 Taco recently an I hope it lasts, it was off the lease of the service manager of the dealership so u would think it was taken care of!~
NO TURBO = NO TURBO PROBLEMS. Maybe toyota, (note lower case) should hire some NISSAN ENGINEERS. How many V6 N/A Fronteers can you buy...all you want.
Hopefully they sort out the Taco and 4Runner driver side lean.
The Tundra engines are also tested to the same standard... And look at the values falling. Main bearings spinning all over the place
I have owned turbocharged vehicles in the past. I liked having no loss of power at altitude. With a hybrid, I am hoping to get better range; in the mountains finding an open gas station can be dodgy at times.
We have 3 Toyota's and I would never buy anything else! Great channel ALL the time.
The turbo charged engines with hybrids are inherently less reliable than the naturally aspirated engines. Every engineer knows that more parts equals more things that can break down. There is a hybrid system, and turbo charger which can break, and also it's a more complex drive train system which equates to more flaws in engineering and manufacturing. Regardless, it's probably as reliable as they can get, which is probably pretty great, but NA engines are better with reliability.
I still enjoy driving my 2006 4Runner V8 Sport Edition! I would have bought a 2025 4Runner, if it did not have a turbo 4 banger. Unfortunately, Toyota is having some issues with their vehicles, which brings in the question of historic reliability.
Won't even consider one until they've proven its not garbage like the new Tundra engine
Just little bit of an issue. $60k later 😂
Can you say 🍋 with me… # TEAM UT
My old 2011 Sienna is at 286,000 miles. These new turbo hybrid’s will not last that long. Bring back the v6’s.
You have to look at it as a system, what is the weakest point? I'm thinking batteries and electric motor/generator, the 4 cylinder turbo could last but the other stuff won't.
If I could spend the money at the time, a 6ft bed Tacoma Trailhunter would be quite difficult to resist. I would like to build a home in a remote area, and the power on board, air compressor, 4x4 capability, towing capacity, and 6ft bed would make pretty much the perfect mobile work bench.
Not convinced!
There’s talks that Nissan is bringing the Xterra back with a V6 engine in competition with the 4 Runner and the Land Cruiser.
No 4 cyl Turbo made in Mexico for me.
Turbo's and Hybrids have been part of Toyota's product line for decades. We have owned 3 hybrid vehicles starting with a 2009. Our first went 14 years and 178K miles and the hybrid system was still working fine. Our second has over 110K and 12 years still going strong. Have a Rav4 hybrid only a year so far, has traveled all over the country and is awesome. 8000K miles so far...looking forward to selling our 5th gen 2014 4Runner for a 2025 it is good, and has 155K miles. Just kinda tired of 15MPG the hunting and lurching 5-speed and lack of modern tech. If I get 12-14 good years out of another car I'm ok with that.
A Toyota Hybrid will be at the top of my list when the day finally comes to replace my 19 year old car with the base 1.8 1ZZ-FE engine and 5 speed manual. We also have a 2010 Tacoma with a 4.0 V6 and 5 speed automatic in the family. In the miles I have driven it, I don't recall any hunting or lurching.
Most of the time our 4Runner is great. Towing or in the mountains is where the old drivetrain shows it's age. Reliable and tough is good, if they would have updated the transmission I may have considered another 5th gen. I am looking forward to the 6th gen, but overall the 5th gen has served us well.
@@kurtburkhardt5862 For many years they have paired the 4.0 V6 with a 6 speed automatic in overseas models like the Prado as well as the Land Cruiser 200/300. I don't know why that never happened here.
How much does it cost to replace a hybrid battery at a Toyota dealership?
One thing to say that they’ve been tested. But what were the RESULTS? How much sooner did they fail?
The 3.5 doesnt have the oil flow when you tilt it. No . I'm serious. If you're ever on a steep hill long shut it off. The oils not getting all the way through. That was a subject online and on TH-cam videos long ago.
So miffed at the $15,000 price increase of the PRO model compared to my 2020. Easily $5,000-7,000 over priced….Especially compared to a Ranger Raptor $57,000 with front locker and FULL time AWD and a twin turbo V6.
Most likely making room for the scout to replace the old Tacoma price range
I’m not an engineer or an automotive designer at all but by watching your videos on TH-cam I probably know more about current automotive engineering than 90% of the people around me.
Not betting my $60k on one. 😂
Toyota has a pricing issue. Go to a dealership and see what you get compared to the prices of the 2023 Taco and 4RUNNER (had both ) They moved production to Mexico (cheap labor) but the savings didn’t go to the consumer. This is why the dealership invented is not moving. I’m a Toyota and Lexus fan that’s why I bought the 2023 GX460 Luxury.
How do you even work on an engine that has an octopus on top?
I like the blue GR Corolla they have just subtly hiding in the background…
Nobody really believes a small turbo engine in a truck will be as reliable as the old 3,5 N/A and especially the 4.0 4runner. We just have to wait and see.
How much is a turbo replacement 🤔 ? Time will tell!
Follow manual on maintenance. Most people will use the severe duty or more aggressive maintenance plan due to stop and go driving, etc.
The owner’s manual actually does recommend idling the engine for a minute or so if you’ve been driving the engine hard just before you stop.
Biggest mistake Toyota has made was hiring an American to design the new Tacoma. Epic fail.
These vehicles are expensive! I would like to see an engine touted as a million mile engine. I think most of us realize at 300-500k miles so may other components will need replacement. Value is a very real and important factor.
Acura 2005 MDX Base over 300000 miles still running.
Why are 3.5 V6 engines blowing up?
