Tundra engine recall - interesting news

I am not a lawyer either but what if this happens to someone whose vehicle is outside the recall window and investigation proves the root cause was engine bearing failure. Not going to look to good for Toyota.

 

I was ridiculed and had virtual tomatoes and booos thrown my way for suggesting the one piece main bearing girdle was the cause of the issue.

 

Pure guess, but as long as it isn’t debris….i think they are good….??? Not the customer but Toyotas butt is covered???

 

@Matt2015Tundra did Ryan release information on the upcoming engine changes? I didn’t see anything on Facebook today. Did he state it somewhere else? I thought today, Sept. 1, was the day he was off sabbatical and going to release a bunch of info per his replies on Facebook posts and per the YouTube video interview.

 

No, Ryan hasn't officially posted anything about the redesigned parts that I'm aware of. I suspect he's trying to protect his inside sources, as well as cover his butt against potential liability.

You have to read between the lines, to come to the conclusion the crank girdle and block are being redesigned.

If you happened to watch the Car Care Nut video in which he dissected a Gen 3 engine that had failed, he clearly pointed out several problems with the girdle/block design. The most glaring problem to me was the fact that there isn't anything preventing the #1 main bearing from walking out the front of the girdle.

I also questioned why there was such drastic differences in how tight the girdle bolts had been torqued. He actually had to cut one of the bolts, after attempting to loosen it with a 4 foot breaker bar. I suppose that could have been due to excessive heat from whatever caused the engine to fail, but I still found it suspect.

Again, the rumors of redesigned parts are unconfirmed, but it would not surprise me in the least.

 

There was a post on the FB group about a month ago that said a design change was coming and that it would be the oil pump. The source didn’t seem very solid, someone knew someone at Toyota they said was a good source. Not saying that is correct just passing along in case someone is interested.

 

that wouldn't surprise me either, the low pressure reading has concerned some for a while now, there was a TSB about the gauge, etc at one time I think as well.

but the speculation wagon rolls on.

what perplexes me is IF this problem is bad enough to warrant a design change , that seems odd to me given so few failures overall.

 

Toyota V35A Oil Pump
Yes, the Toyota V35A-FTS engine uses a variable oil pump. The pump is chain-driven and features an electrically controlled solenoid valve that regulates oil pressure based on engine temperature, speed, and other parameters. This system allows for variable oil flow and pressure, improving efficiency and ensuring adequate lubrication under varying operating conditions. The pump's operation is managed by the Engine Control Module (ECM), which controls the pump via an oil pressure control valve to maintain optimal pressure

This all just sounds like a really bad idea to me, and I agree, it's all emissions and fuel saving related. The engineers are trying to provide the bare minimum oil pressure that they *believe* will be adequate, all to just save a little bit of friction losses from maintaining constant oil pressure??? Someone needs to write a Forscan for Toyotas that allows users some control over this nonsense and just let the damn oil pump, pump oil.

 

I firmly believe that just about all new vehicle problems are caused by all this Cafe and emissions bullshit.

I don't want to get the ban hammer so Im leaving politics out , just talking regulatory wise.

 

It's been happening since the mid '70s when the EPA began regulating emissions under the authority from the Clean Air Act, and it's been getting worse ever since.

I'll never forget when I first looked at my Father's 1982 Jeep CJ7's engine. I had a 1979 CJ5 at the time. I could not believe the maze of hoses, sensors, switches, wires, and other crude emissions contraptions in my Father's Jeep compared to mine. It was like I was staring at a different engine even though they were both the same 4.2L I6 engines.

One of the most popular modifications on those '80s era CJs, with all the problematic emissions crap, was called the Nutter Bypass. It bypassed the crude computer and all the trouble-prone emissions systems by cutting and splicing 2 wires. There's probably only a handful of CJs on the road that still have that garbage in place and operational.

 

Nope.

And let me guess, it was in the 2023-2025 Toyota Tundra Owners group?

 

It's not broken yet. Why not move on from it? That's what I would do anyway if I was worried.

 

First generation catalytic converters came out roughly when? '74-'76? Somewhere in there, at least on GM's. Those boat anchors weighed a ton, had similar flow when new of sticking a banana in your tailpipe, and clogged up if you looked at them cross-eyed. Created an entire industry for "test pipes."

 

Just bad engine times. Toyota 3.4. GM.6.2. Nissan VCs. Some Ford Coyotes and Ecoboost variants. Honda 3.5. Now Kia/Hyundai forgot a couple turns to tighten the bolt on connecting rods so you got free floating bolts in your engine.

Everyday another bad news engine story.

Mix of design and manufacturing issues. So not sure any engine line is 100% safe these days. If the design is good you got various nonsense happening down at the factory or component subcontractor

During the COVID chaos god only knows who was manning the shops for components and subassemblies. Hyundai got caught using child labor for subs. Illegals probably made it into the workforce as subs as well.

No problem, the filter will catch those. ;-)

 

I was a builder back in the day. The fix everything was caulk. Many subs thought they could just half ass cut everything then bring out the caulk gun and it's all good.

For engines it's now filters and weekly oil changes to try and save the day from shotty work.

I was thinking about this last night, I have been driving for 48 years, countless cars, trucks, motorcycles and RVs. Pretty good mix of used from my very first 1965 Plymouth Fury III bought after a summer working on my uncles farm, and driven home across 4 Canadian provinces to many brand new Lexus, Mercedes, and domestic. Not once in all those 48 years have I been left on the side of the road broken down. The only major problem ever experienced was with our Honda Odyssey transmission going out at 60,000 miles, just out of warranty but Honda replaced no charge. That's it.

And it's not like I've only owned new vehicles for 2-3 years before trading in etc. Typically keep vehicles for 9-10 years and I've owned some notoriously unreliable vehicles: Ural sidecar, 3 Moto Guzzi Italian motorcycles, my wife and my current rides.

What a sad state of affairs that in this day and age this is the best that auto manufacturers can give us. Pure sh!t.

 

Same here. Been driving for 47 years. I had an old Jeep that would occasionally overheat, requiring me to pull over to let it cool down and add some coolant. But it never stranded me on the side of the road.

Then came 2022, when my wife's BMW X5's engine seized up and left her stranded. 80K miles on the car, so no warranty, and we foolishly didn't buy an extended warranty. The dealership where we bought the POS, and had done all the maintenance on it, wanted $5K just to diagnose the problem. The most likely outcome was it needed a new engine for another $25K. At that point, the repairs were going to cost more than the car was worth. After 6 months of getting nowhere with BMW, we reluctantly accepted a token $1500 check from the dealership, and left the POS sitting in their parking lot.

And now, I'm driving a $70K truck that has a small but very real possibility of blowing up, too. Unbelievable.

 

You're never going to like the Tundra or Toyota or BMW. You can rage eternally or move on. Life's too short.

 

Move on to what? Another POS to rage about?

 

Yes. no future in hanging on to something that doesn't work for you made by a company you don't trust.

 

You know the answer, the only answer this 3rd Gen forum knows - the 2.5 Gen Tundra.

 

My point is, there isn't any greener grass to move on to in the full size truck market, IMO. They all seem to have warts.

 

So I guess you just hang out and be miserable?

 

I’ve had great cars from all these brands. But that was many years ago. What we are all “raging” about is the current state of the automotive industry. The offerings are astronomically expensive, fragile, and mechanically unreliable.

 

For a variety of reasons I don't like Gen 2.5 and wouldn't want one. That said, if you hate the Gen3, think Toyota is a bunch of liars and think the dealers are worse, owning a Gen2.5 that is serviced at an indy might be a good choicer some?

 

I am only bringing this up to play the devils advocate. But do we really think cars/trucks are actually getting worse? There are more vehicles on the road today than ever before. And with the internet we all hear about every problem. Vehicles have always had issues, we just never heard about them the way we do now. Even the Tundra (so they say) only has a ~2% failure rate....but with 500K of them on the road that is a big number compared to only say selling 250K maybe 20 years ago....if that make senses. lol

 

They are selling a lot of tundras at current prices. Even with the engine issue, people are still buying. This is what inflation looks like. Covid brought historic inflation. You can’t put the genie back in the bottle. It is what it is. You have to adjust. This is a government problem as much as it is a car company problem.

 

LOL. I'm far from miserable.

I don't get emotional about vehicles, except my Father's 1981 Jeep CJ7 that I completely restored a few years ago. It makes me think about him every time I drive it. RIP Dad.

 

They aren’t selling one to me
