Toyota Tundra 3.5L I-Force V6 MASSIVE Engine Issues *Heavy Mechanic Review* | 24TA07 Engine Recall

well I think it's time we relook at the Toyota Tundra with its 3.4 l twin turbocharge V6 because there is some tough news that dropped indicating that these engines could fail at any [Music] time welcome back to the channel I'm Alex and well last time we tried to talk about issues with this 3.4 l twin turbox engine it went South very quickly my own fault I had the wrong information but today is a new day and well with the bombshell information that dropped on May 30th I figured it's time we make this video and talk about the recall these engines are having with that being said I do still want to talk about the turbo issues with the 2022 trucks so let's start off there the first issue associated with this engine and has been relatively highly discussed is the electronic turbo waste kit actuators failing we don't know if it's the actuators themselves or or software related to them either way um the earlier models especially the 2022 have been somewhat plagued by this issue when these actuators fail the truck will be put in a limp mode because well it's pretty critical to any turbo if and when they fail the truck is still going to be drivable and so you won't need a tow apparently this is a manufacturing problem not a design problem which is good news there and Toyota has resolved the manufacturing issue so going forward we should not see um any wastegate failures however since the waste gates are integrated with the whole turbo the whole turbo has to be replaced um and on this engine the turbos are stuffed back there and I guess the only way to really access them um and replace them is that the cab kind of has to be removed from the truck um so you can gain access so it is not going to be um a very quick repair it's going to be a very timec consuming repair now despite this repair being covered under warranty and costing you nothing um it would still frustrate the heck out of me knowing that this whole cab would have to be removed I mean think about how many wiring harnesses are going to be disturbed connectors being unplugged how many things have to be unbolted and the odds of everything going back exactly how they were when it left the factory floor is almost impossible I mean myself as a mechanic it's just it's as simple as putting a zip tie in the wrong location um and then next you know that wiring harness is rubbing on something and then you got electrical problems down the road so it would just frustrate me knowing my new truck was all getting ripped apart um to fix this issue it seems this issue is contained with the 2022 model year trucks if you got anything above that 2023 and above you should be okay um however if you do have a 22 and your truck suddenly goes into limp mode odds are you might have a turbo waste gate issue the second issue that does concern me a little bit more is the reported engine failures apparently some of these engines are having um bottom end failures or spinning main bearings and while resulting in complete engine failure and this does seem to be encompassing all of the third gen Tundras we don't know exactly what's causing these engines the main bearings rod bearings to fail um Toyota has been I guess keeping to themselves on this issue and that brings us to today because we do now know the reason why these engines were failing the main bearing failures and we understand why Toyota wanted to keep tight lips around this because it is a pretty big issue the official recall on our official Tundra here was dropped on May 30th and it is 24 ta07 I'll put a link Down Below in the description you guys can check it out for yourselves basically what this recall is saying is there is metal debris left in the engine from manufacturing processes and this is resulting in main bearings being destroyed taken out resulting in more or less complete engine failure now there's a couple things I want to dive into because I feel like this story is just starting and potentially far from over but let's start with the basics what the hell is a main bearing these right here are main bearings out of a Detroit diesel engine so much larger than what's going to be in your Tundras but they serve the identical purpose basically your crankshaft spins on these main bearings now probably to the average person these things don't look like what you would expect bearings to look like but what the key to these things is is that the crankshaft doesn't actually spin on these bearings themselves there's a very very thin layer of oil that separates the crankshaft to the main bearings and the actual crankshaft more or less floats on a bed of oil that is why oil pressure is so critical to an internal combustion engine because if that oil is not there your crankshaft then actually spins on these main bearings and well these things get hot really quick and uh can fail extremely quickly without proper oil here the last thing I wanted to point out about these main bearings are they're typically made of layers of softer metal so you can kind of see um on this engine crankshaft was starting to get into another layer there which is you know not terrible you it's pretty typical for a used main bearing but if you guys can see kind of this scrape right along here this is a little piece of debris that got in between the crankshaft and the main bearing and why there are layers of softer metal is that these can actually absorb debris and we kind of see it right there with the scrape and it protects the crankshaft but when we start getting into bigger metal debris or metal flakes which allegedly is what's happening with these Tundras that very critical layer of oil between the crankshaft and this main bearing gets disrupted and these things get very hot very quickly and they fail as I mentioned the metal debris is allegedly from the Machining or the manufacturing process when making these engines in these Tundra trucks and it's very unlike Toyota typically when I think of Toyota I think of a very well-manufactured engine which gives them you know all that reliability typically with a Toyota engine first we see the manufacturing issues with the turbos and now we're seeing manufacturing issues with the engines themselves which is it's a tough look so what is Toyota to do about this with their trucks well we don't really know and it seems like Toyota themselves don't actually know what they're going to be doing with this because even in the call it states they actually don't have a resolution just yet Toyota will most likely have a solution here in the next couple weeks at least you would expect that um but what they're doing so far with these engine failures is Toyota is shipping a short block to the dealerships and the dealerships are rebuilding the engines now a short block is basically the engine block and the rotating assembly Pistons crankshaft and the top head of the engine is being rebuilt and reused and reassembled on these trucks if the on my own brand new Tundra truck here behind me was to poop out let's say I'd want a brand new engine put into the truck I really wouldn't want my engine to be more or less rebuilt at the dealership and then put back into my brand new truck which I just spent a heck of a lot of money on I got nothing against the Tex at Toyota or the dealerships themselves but myself as a heavy duty mechanic having rebuilt engines I know that when you rebuild an engine you put components on benches and at times they sit there for days days when you're working in an active shop like a normal dealership you are going to get dust and debris on those components and it's extremely hard to ensure that all the componentry is clean when going back into the engine and well this whole recall is to do with what debris in the engine causing problems so yes Toyota is sending a short block but this is a dual overhead cam setup engine all your timing cam shafts are all up in the heads which are going to be reused and reassembled and so that componentry is going to be taken off the engine put on a bench and ideally covered but again you're working in an active dealership and you're just not going to get that cleanliness or that proper fitment that you will at factory personally I think it's a little bit cheap from Toyota people have spent a ton of money on these brand new Tundra trucks and metal has gone around the engine so replace the engine and move on the final mail in the coffin for me on these engine failures this engine recall is that Toyota allegedly knew about this issue since February of 2023 not 2024 February of 2023 what almost 16 months ago and even on the recall on the first page you can see to February 2023 so they knew about this issue yet they kept their mouth shut and maybe we're just hoping to sweep the sun of the rug hopefully only a couple engine failures but I think it got to a point where they could no longer ignore the problem and well this is why we get this safety recall so again a pretty tough look and they still don't have an official remedy for this problem with almost the 100,000 trucks that have been recalled so allegedly if your truck is built after February of 2023 you should be okay but I don't want to get myself in trouble here it does still seem that some 2024 engines are having main bearing failure problem so this is why I think this story may just be beginning it also seems like there are some engines that are made in Japan that are also failing which are not manufactured in the US which allegedly was the whole problem to begin with so I think there is more to come so they do have some tough sledding ahead of them lastly the hybrid engines or the I force Max engines are currently not in this recall maybe they're assembled on different assembly lines which is why they wouldn't have this debris in them who knows but I'm sure there's going to be more to come this is a safety recall and Toyota does state that well if there is complete engine failure on those hybrid trucks they will still be able to move and get off the road and drive for a little bit so that could also be why it's not included in the safety recall because technically if there is a complete engine failure it is not unsafe to drive the vehicle so maybe those engines are just as likely to fail but it's not a safe concern if that makes sense so those are the two major issues with these Toyota Tundras and their 3.4 l twin turbocharge engines unfortunately with new engines there are issues that will always arise and W it just happens that both of these issues are pretty large the last thing I wanted to quickly talk about is just the complexity of this twin turbocharged engine when looking at the predecessor the 5.7 pretty simple V8 people loved it it was reliable and had a pretty darn good track record but this engine is pretty tightly wound up as someone commented it's a whizbang of an engine so I always say Simplicity usually leads to reliability and this new engine is pretty far from simple typically I would give Toyota the benefit of the doubt because normally they do produce very very quality engines however the quality control thus far on the third gen Toyota Tundra built out of Texas unfortunately has been extremely subpar if you guys are looking for a Toyota Tundra I would wait pump those brakes I'd wait at least 6 months maybe a year for those 2025 maybe even 2026 models when all of this stuff has been completely ironed out um if you're in a dire need for a Toyota Tundra go look at a 2012 to 2021 with a 57 you're not going to be disappointed they're very quality engines and if you're desperate for a twin turbocharged truck head across the road get yourself an F-150 with a 3.5 L EcoBoost they're just as expensive except they come with more power they're more fuel efficient and at this point they're probably more reliable very very interested in what you guys think um issues arise in engines all the time like we say no engine is perfect but it seems like at least in my opinion the way Toyota has dealt with this issue so far just seems a little bit disappointing um especially given that these trucks well are not cheap and the issue at hand is a very very large one so we'll have to see what Toyota comes up with in terms of a solution for this but for now at least in my opinion it's a little bit disappointing let me know what you guys think if you did like the video don't forget to leave that thumbs up and well if you like cool stuff like this don't forget to subscribe because we'll be following this story pretty closely I'm very very interested to see what happens with these engines because as we know Ram is releasing their inline 6 Twin turbocharge engine this year and I can't help but see some similarities between both platforms they only offer one engine all their eggs in one basket so it will be very interesting to see what happens with these engines and um anyways enough of me we'll see you in the next freaking video
