Turbos ate fine in heavy duty applications (Cummins commercial trucks) and high performance applications.
They have to be overbuilt and do a great job with heat displacement and lubrication.
I'm not convinced a small-displacement gas engine is such a great idea in a full-size pickup, turbo or not.

No, but poorly lubricated turbos definitely are

Part of the reason diesels hold up so well is they pump A LOT of gooey oil all the time.
When you start metering oil flow to try to match the exact needs you make problems. Oil handles a whole hell of a lot of heat transfer in an engine in addition to lubrication. Its a big driver of all the cam and lifter problems engines all of a sudden have, in 2025, about 100 years after hydraulic lifters first became a thing.
Stick a turbocharger on it, pump a limited amount of watery oil to everything, and hot start/hot stop the engine 50 gazillion times per trip, and voila, engine problems.

Remember when GM first put turbos on those on those V-6s and small V-8s and they coked up and came apart on the reg?

I don’t trust reliability reports.
Because they don’t weight the type of problems that are issues.
I will deal with issues that I can repair myself (for cheap) as long as the engine, turbo, and transmission are solid.
Most of these surveys will count every little rear view mirror motor and knob that breaks as an incident.
One of them gave Tesla a horrible review because of all the “recalls” which were software updates done at night over your wifi.
I believe all reliability studies were paid for by the automobile maker that wins the study.

The 5.7 was GMs best engine. Poor gas mileage but that was a great engine. Still have my old 98 z71 at the farm. 340.000 miles and still running great.

Sorry but what do the numbers on the right indicate ? Percentage of cars requiring repair ?

How does ford get away with still offering the 5.0? Imagine if Toyota could/would still offer their V8....
Chevy still putting V8s in their trucks too. We like to blame the Feds for all these regs, and they deserve it...but Toyota is clearly doing more than they "have to" unless I don't understand the regs correctly.
Being able to buy naturally aspirated engines and non-CVT transmissions are the starting point for me buying a vehicle.
That almost rules out Honda all together (aside from the lovely V6 Passport). Rules out Eco-boost. Rules out ALL toyota trucks now.

It's not like they don't suffer from the same "modernization" of their gas counterparts.
Low sulfer diesel, particulate filters, high pressure fuel injection, DEF, regens...they are not anywhere close to as durable, reliable, or long lasting as the trucks that predate all this.

It’s not that, it’s the start/stop feature. Oil doesn’t run through the turbo when the engine is off, so it’s getting cooked.
Almost no OEM vehicles use turbo timers and never have so that isn't the problem. Modern oils can handle that aspect easily. The problem is in fact the use of smaller, turbocharged, higher-stressed engines that are using thinner oils and thinner, lower-tension ring packs to meet CAFE and do better on EPA fuel economy standards. Engines are also being run at higher temperatures to get better efficiency, which creates its own set of issues. An older MB turbo diesel on modern synthetic HDEO would absolutely have fewer issues, they were tanks even on crappy oils.

And both are having more and more problems trying to meet CAFE standards while still offering those V8's. GM recalling 6.2L engines due to bearing failures, one of the changes is to switch from 0W-20 to 0W-40 oil. Ford's V8's don't like xW-20 oils either and I've never ran anything thinner than 5W-30. Same exact engines offered in other countries spec xW-30, -40, -50 oils....countries where CAFE doesn't matter but longevity and reliability do.

I have a Tundra with 250k miles.
Never done anything but an oil change.
Can any F150 people say the same?
Chevy?
I bet not.
I’ll take the Tundra over anything.

I can only assume these opinions are meant for JD Power.
CU is non-profit and does not even accept advertising for their publications or website. They provide the most statistical and detailed data for car reliability available to the consumer in a one stop shop. The only better information you will get is spending many hours sifting through brand/model related forums which I do recommend if buying a vehicle.
Thier reviews of cars are fairly useful for most people. They lean toward testing them as an appliance so if you are interested in how they perform at 90% of the limit there are better sources. If you want to know how a car functions in day to day life their reviews are useful.
They own a huge car test facility.
Across the board you may not like their methodology for specific products but calling them paid shills is silly and baseless.

List is shite! The hybrid iforce engines in tundra’s haven’t been plagued with the regular turbo6 problems.
Yeah they are failing left and right. They just haven’t been part of the safety recall like the non-hybrids because the electric motor can at least get the truck a few feet off the highway when the turbo V6 seizes.

frick, I feel like I am knighting for CR when it is nothing but one tool in the toolbox...
CR does weight problems. They also give a breakdown of where the problems are. For example they break powertrain issues into 9 different categories for every car they provide reliability info on. In all they report on 17 different reliability areas, overall reliability and consumer. Beyond this they provide information about exactly what issues come up routinely in each of those 17 areas. So you can see if a car has a rock solid power train but has all sorts of issue with trim falling off and the infotainment system screwing up. That vehicle might make a great 3rd vehicle because you don't care if the trim needs to be constantly glued back on etc.
This is the chart form of reliability information for a very reliable car from CR
