ENGINEERS REVEAL RARE FACTS ABOUT 4RUNNER, TACOMA, LAND CRUISER - CANDID INTERVIEW SHELDON BROWN
Автокөліктер мен көлік құралдары
Two engineers - David Chao & Tacoma Chief Engineer Sheldon Brown - discuss sensitive topics about the new Toyota 4Runner, Tacoma and Land Cruiser. Will the new turbocharged engines really last as long as naturally aspirated engines? What really happened with Tundra's wastegate issue? How much does the 2025 4Runner share components with the new Tacoma and Land Cruiser? Who is the Chief Engineer for the new 4Runner and Land Cruiser? There are so much insights revealed in this video that you won't be able to stop watching until the end...

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!!!
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
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.

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.
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
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.
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.

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.
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.
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.

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.

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."
So will the turbo 4 also have a spun bearing issue?
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.
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?

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.
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?

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 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.
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.
Please do a video specifically about main bearing failures in the V35A-FTS engines. Would like to know how Toyota plans to address this.
The Tundra engines are also tested to the same standard... And look at the values falling. Main bearings spinning all over the place
Hopefully they sort out the Taco and 4Runner driver side lean.
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.
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.
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.

Masters compete with each other,nice!
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.
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.
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.
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.
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.
One thing to say that they’ve been tested. But what were the RESULTS? How much sooner did they fail?

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.
My old 2011 Sienna is at 286,000 miles. These new turbo hybrid’s will not last that long. Bring back the v6’s.
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.
Poor guy, having to answer the tough questions. Good job automotive Press. And even though he probably wasn’t able to answer or provide quite the correct answers on everything, he did a good job answering difficult questions. The price is insane, so nothing he could say would be a good answer there.
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.
No 4 cyl Turbo made in Mexico for me.
Won't even consider one until they've proven its not garbage like the new Tundra engine
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.
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.
Follow manual on maintenance. Most people will use the severe duty or more aggressive maintenance plan due to stop and go driving, etc.
Why are 3.5 V6 engines blowing up?
How much is a turbo replacement 🤔 ? Time will tell!
I like the blue GR Corolla they have just subtly hiding in the background…
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.
Just little bit of an issue. $60k later 😂 Can you say 🍋 with me… # TEAM UT
How about offering us an sr model with trd pro offroad goodies. Eliminate the infotainment and other accessories to keep cost down.
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.
Acura 2005 MDX Base over 300000 miles still running.

Biggest mistake Toyota has made was hiring an American to design the new Tacoma. Epic fail.
