Used in certain pickups and SUVs,2022-24,failing from "spun" rod and main bearings,dealers will replace engine "short block" assembly with a new one re-using the cylinder heads from original engine.Machining debris left in engine oil passages during engine manufacture at Alabama plant is blamed for the bearing failures.Some no-official sources suggest faulty engine oil galley design and/or use of too-light oil viscosity is the real cause...The Hyundai/Kia engine failure episode of a few years ago was also blamed on metallic debris left in engine during manufacture.
 
original engine

Wondering what the factory flat rate time for this operation will be, having worked at a Lincoln-Mercury dealership for many years I know it will be something ridiculously low.

Otherwise, you know for a fact that heads will roll for this one, not only at the engine plant, but also in Toyota's headquarters in Japan.
 
identical (or revised )replacement short block...

...depending if Toyota considers cause to be the machining debris or oiling system design fault.Lots of chance of dealer mechanic errors in engine removal/reinstall not to mention removing and reinstalling cylinder heads and other parts off the failed engine onto the new short block...Complete new engine would be better,but subject engine is a complex,expensive, DOHC twin-turbo v6...
 
Using small engines and turbos to achieve what used to be accomplished with properly sized naturally aspirated engines is proving to be a disaster in all makes and models across the board. Another bonehead idea to save a few ounces of gas at the risk of thousands in damage and repairs.

I'm sure the future will be riddled with more stupid ideas that will cost the user even more money and downtime. I'll just keep driving my old stuff as long as I can. I've joked in the past about going back to a Model A rather than being forced to buy new. That just might happen.
 
Using small engines and turbos

So true, so very true...

When the Fox body Ford Mustangs and Mercury Capris were introduced back in '79, I special ordered a Capri hatchback pining for the 2.3 Ford OHC turbo 4 cylinder, however the motor was not yet available as an RPO option, it was still undergoing engineering review.

Instead I opted for the tried and true Windsor small-block, a 302 V8 mated to a C4 transmission.

My choice proved to be very wise, when the 2.3 turbo was finally released for sale, it had a propensity to create "viewing ports" on the side of the cast iron block caused by a connecting rod which decided to part company with the rest of the motor, usually # 2 cylinder.

Several Ford TSB's were released to address the issue, which involved lowering the waste gate release pressure, it didn't help at all.

I was 24 years old at the time, working as a mechanic at a Lincoln-Mercury dealership and remembering replacing several long-blocks of the star-crossed motor in Capris and a few Zephyrs.

My current stable consists of a '22 Toyota 4Runner V6 and a '02 Honda CR-V, both naturally aspirated, my "go fast" days have long since gone...
 
Engine and transmission failures in newer Cars

Almost all manufacturers have had trouble with engines and automatic transmissions in the last two decades, as transmissions and engines have been redesigned for greater fuel, economy, and lighter weight. Overall, there’s very little difference in the reliability of different major brands anymore Ford Chrysler, GM Toyota, especially Subaru of all, had engine problems, in fact, I think everybody I know with a Subarus had an engine put in it at some point it’s got some age on it and mileage.

The good news is cars are still lasting longer than ever and requiring less service, but people are putting more miles on cars than ever.

Fortunately, there’s a solution and it’s coming at a pretty good rate called electric cars. All electric cars are incredibly reliable requiring very little maintenance, the future is good.

To quote Harry Wormwood from Matilda: “Of course it’s cheating, no one ever got rich being honest”.

Sums up the current auto industry perfectly.
 
“I’m sure the future will be more riddled with more stupid ideas that will cost the user more money and downtime”

I saw this coming as far back as 10 years ago, hell even 14 years ago. Tired to warn people, now here we are. People just don’t understand until it’s too late. Oh well, one’s foolish decisions just makes more more wise, wise beyond my years.

Putting low tension piston rings in is the equivalent of putting in worn ones from a junker engine, many of these late model vehicles basically are high mileage from the get go with low tension piston rings, that’s why they consume oil before 100,000 miles, some even at 75,000 miles.
 
Low tension piston rings coupled with oil change recommendations of 10,000 miles or greater is definitely a recipe for disaster. Ultra thin oils possibly causing accelerated wear in the name of efficiency. There are now engines out there calling for 0W-8 oil. How much protection is that providing, especially in hot environments or high loads? Would you trust a 0W-8 oil in the engine of a truck pulling a large trailer up a steep hill on a hot day...with a turbo (turbos are hard on oil)? I certainly wouldn't.
 
Seeing the state of new cars...

I’m grateful to have my 2006 Pontiac Vibe. She has a 1ZZ-FE engine (the revised version that doesn’t burn oil), a regular four speed automatic transmission, non-flammable A1 rated R134a refrigerant in the A/C system (which still blows cold), and most of all, NO touch screen, turbocharger, ultra low viscosity oil, gasoline direct injection, or loose engine tolerances. And guess what? She is still capable of 30 MPG. As such, I fully intend to drive this car to my grave.

Re:#11

I’m with you thatwasherguy!

I have a 2007 Honda Civic 4dr that I bought new in March ‘07 and it also has none of that new fangled nonsense. Only 65,000 miles gets great MPG with the 4 spd auto trans and I also plan to never buy another car.

I’ve owned 23 different cars from ‘69 to today, 55 years and “Ruby” my little red Civic is my 5th Honda and is the best, most dependable car out of all of them. The only thing I’d change is the visibility, the steep, low slant of the rear window , combined with the headrests on the back of the seats limits the visibility.

I wouldn’t have one of the new cars if you gave one to me. I used to buy a new car every year or so. If someone had told me that I’d own the same car for 17 years I’d have said no way.

piston rings...

When I attended Honda automobile training sessions back in the early 80's, I remember an instructor sharing an interesting story with the class.

Honda had introduced their "Civic" line of cars in '72, it was powered by a diminutive 1200 cc inline 4.

Soichiro Honda insisted that the contract to provide piston rings be given to his nephew, who was a rather large manufacturer of internal engine components.

As it turns out, said nephew knowingingly produced and supplied inferior rings, as a result the little motors burned oil like crazy.

Old man Soichiro was infuriated when he found out what had happened, the Honda name was severely tarnished as a result of his nephews actions.

As the story goes, Mr Honda went to his nephews office and laid a sword on the nephews desk, telling him "you know what to do".

It's unclear if said nephew did actually perform "hara kiri" on himself, as his Uncle had instructed.

Having grown up in Hawaii, met and befriended many Japanese acquaintances, the very last thing you could ever do in life was to draw shame to the family name or "mon" (crest).[this post was last edited: 7/29/2024-12:02]

While these engines are having serious issues, Toyota is actually recalling them and fixing them. Certain manufacturers would never do this. They are actively trying to fix this from happening by doing the recall. If anything, that does build more confidence back up. I know a few that have 22 Tundras and have not had an issue. Though, I also wonder if too think of an oil viscosity is an issue.

10,000 mile oil changes are just a way to make the engine wear out as soon as possible, auto makers are in the business to make and sell cars, not make them last a lifetime. Same could be said about oil change intervals back in the 60’s with 6,000 mile intervals, might explain why engines were worn out at 100,000 miles back in the day and why surviving examples that had the oil changed every 3,000 miles with over 100,000 miles are still running. I never buy the suggested oil change intervals, always go by 3 months or 3,000 miles, transmission fluid changed every 2 years, same with brake fluid, coolant too.
 
Overall, new cars are so much more reliable

And longer live than anytime in history, and it looks like it’s only going to get better.

Just like Eddie’s experience every car I’ve gotten has been better than the last, I had four new trucks first one in 1983 Dodge tradesmen with a four speed on the floor and slant six and factory air, Then 1993 A short Dodge caravan, four-cylinder, automatic factory air, then I got used 2005 Dodge caravan, and my current vehicle is a 2017 ram Pro Master city, four-cylinder, nine speed automatic, it’s pounded through city traffic every day for 75,000 miles now without a single problem.

I bought my first ever personal vehicle almost a year ago. Chrysler Pacifica, all-wheel-drive heavy duty minivan with trailer to have it found so much as a loose screw on it unbelievable, well built things today.

As far as maintenance and oil changes go I do with the manufacturer says they know best what the vehicle needs for normal use. I never drive my vehicles over 200,000 miles so I’m not going for a record. I’m not gonna waste my time and money changing oil more often than necessary,

The more than 40 vehicles that I’ve been responsible for in my life. I’ve never had an engine problem of any kind so changing the oil more often would never have done any good I have gone as long as 10,000 miles on an oil change when they were recommending that now. I just left the computer determine when to do it usually it’s somewhere between six and 8000 miles .

Lower viscosity thinner oil will always give better engine life in addition to better gas mileage, but engines have to be built for the lower viscosity oil. You would not want to put a very thin, low viscosity oil in an older engine or one that is significantly worn.

Subaru extends warranty

Quite often Subaru has extended warranties to cover engine problems. I have had two Subarus, 2018 Legacy and current 2023 Legacy. The manufacturer requires oil changes at 6000 miles or 6 months which ever comes first. This car also has the CVT transmission and I believe the current versions are quite reliable. The dealer treats me very well and I feel like I am in a Cadillac or Lincoln dealer, I have had both in the past. And I know this is dumb but I have a factory CD player in the 2023.
