I'll answer my own question...CAFE standards and loopholes. SUV's - even when built on a car platform - are considered trucks and held to a different standard.
And...you're probably right. Planned obsolescence.
GM just warrantied the turbo four-banger in Chevy trucks to 100,000 miles. They bally-hooed that engine as being built to diesel standards.
It's still a piece of crap that wouldn't tow a pregnant whore on a pisspot.

Is the pisspot full or empty?

Ax, it doesn't matter. Either subset is true.

Turbos have definitely gone through growing pains - but it does seem like they're getting more reliable. About 20 years in, kinks seems like they're being worked out.
I'm floored at the torque, HP and fuel economy numbers put out by some cars these days. I have no opinions or experience on how good they are in heavy-duty trucks.

Learned a little more about diesels after getting curious here. Seems like diesel engines need a higher compression ratio than petrol. Turbos help push in more air than naturally aspirated. Turbos also kick in at higher RPM where diesels are weak - they have power for days at lower RPM.
Higher compression ratio also typically means stronger engine components are needed. Strong engine + turbo works well from a reliability standpoint.
So yes - that's all to say, Renauda is right.

When your turbo fails, what should you do?
Reduce throttle to maintain engine power.
Reduce to maintain, don't you mean increase throttle to maintain?
Nope, no turbo means less air. Less air means less fuel is needed to maintain mixture.
Of course this depends on altitude. At a lower altitude the turbo may not be adding much air.

"Turbo lag" is a real and annoying thing. I don't remember which of my cars had an early turbo, and it took some real getting used to.
My current car has a 2 liter turbo - and you'd never know it.

My mom's early 2000s Acura SUV had an old school turbo. You could feel it kick in half way through the rev range. It had that distinct air pressure loss sound with every gear shift "PSSSsss".
My current vehicle has one - there's not way to tell there's a turbo in there. It has a twin scroll that lets gases in at low and high rpm differently.
They've come a long way.
