It just appears to me that manufacturers are trying to squeeze too much power out of too small of an engine by putting turbo chargers on tiny power plants and then installing it in too large/heavy of a vehicle. This makes the engine work too hard and wear out early. Look at the size of the connecting rod bearings and caps and timing chain and other major components in that tear down video. It looks more like an engine for a small motorcycle instead of a full size car.

I've always bee leery of small displacement Turbo engines. When I bought my Silverado, the salesman tried to talk me into the 2.7 turbo. Seems they had a lot of them sitting on the lot. I pull a midsize toy hauler.
I bought one with the 5.3 V8. Lot's of power and no high revving.

It’s just not Honda… engines of all brands are having valve train and camshaft issues and it’s been traced directly to the use of low viscosity oils to gain that .001 mpg needed to meet EPA standards… factory tech bulletins are being issued to use higher viscosity oils to prevent failures. ….. its not the tech working against the customers but the EPA and Emmisions standards. …. manufacturers are clearly trading reliability for efficiency. … it’s not just autos … AC units in buildings are now throw away because the condensers and evaporators are so thin they can’t be fixed and fatigue fail quickly. …. It was only a few generations ago an AC unit was built to last 40-50 years…. Now they last 6-10 maybe. … it’s an efficiency tradeoff… what was unacceptable 40 years ago is now the design standard. … and for some reason people think this is ok…

My neighbor has a Chevy 6.2 liter engine in his truck. He received a recall letter about engine failures due to lubrication problems with the recommended 0W-20 oil.
It was recommended by GM to the dealer to to start using the Corvette 0W-40 oil until a resolution is found.

All vehicle makes are having problems.

These small displacement turbo's may be fine for race cars. They are rebuilt or replaced after each race. Jut another government mandate to reduce weight.
Like removing spare tires and using more plastic body parts.

The only problem is, there is no where to turn to. Seems that every manufacturer is having major engine problems on many of their cars and trucks. My belief is that most vehicles being sold today will be mechanically or electronically totaled long before they reach 200,000 miles because of the high cost of repairs.

It took years for the companies to redesign and retool the plants to produce these engines.
I agree about the electronics. Digtital this and that and 12-15 separate computers.
Everyone wanted a Smart Phone on wheels. I cannot imagine what the 30 inch display will cost to replace and how long it will be available.
Just like TV's, it's going to be a throw away item.

Honda is putting a 1.5 liter turbo engine in 4 door Accords which is a 3,500 lb car. I call that a small engine for this size of a car. The larger engine option with the hybrid is a 2.0.

My 2001 Accord has a 3.0 liter V6 and it makes about the same horsepower as the newer 1.5 turbo, but is a much larger/stronger engine with a great reliability record. I've just decided I'm going to freshen it up and see if it can make 300K miles instead of replacing it. I already started on it today, and I'm replacing a leaking radiator, fixing a couple oil leaks, adjusting the valves, and replacing the standard tune-up stuff on it. I've already checked some of the valves, and at 220K miles they are still at center spec. I think I last checked them around 110K miles.

Maybe when Honda gets around to fixing their current head gasket problems I'll think about replacing it.

That was before all the weight, fuel mileage and emission regulations started hitting the fan.

Do they it require an initialization procedure like the DCT? 🤭

The only initialization is a slap of the harness and maybe an occasional Giddy Up.

I have delt with quite a few turbos since our family 1963 Corvair Spyder. And yes, I still drive Corvairs. My 1964 Corvair Greenbrier Van has 375,000 miles on the clock. 300k of which I personally have put on it. No.... not a turbocharged engine! 🙄
Turbo's increase performance, But with that require "proper" lubrication and in general have little long term reliability. At least that has been my experience.
Ay Fred... For fun, if you have a chance, test drive the latest 2025 Honda Accord Hybrid. 4 cl and no Turbo. I have just bought a 2025 Civic Hybrid Hatch Back. Same drive train as the Accord. No CVT transmission. These are electric motor driven, unlike other Hybrids. This is the 4th Hybrid we have had in the family. The Honda acceleration and performance is amazing. Beats the Prius, of which we have also had.

Dave, did Ralph Nader know about your Corvairs?
I worked for a car dealer while in High School in the late 60's. They took in a Spyder on trade. Damn, that car was fun to drive. Too bad I couldn't afford it. I was only 16.
