“Government regulations including EPA reg. made them make changes not compatible with longevity.”
Which regulations affected those components? Hard to imagine any. So I’ll stick with DEI, specifically incompetent people making the small decisions that can ruin the end product, such as which metal alloy to use...seen that first-hand.
Aluminum engines
Aluminum Engines are the direct result of EPA MPG mandates.
Anything to reduce weight and increase EPA MPG.
“Which regulations affected those components?”
CAFE standards. The “super cruise”, or whatever they call it, doesn’t allow for adequate lubrication of the engine components while it’s engaged.
Or so I’ve heard.

The basic one is the CAFE mileage requirement constantly increasing. Lots of minor and not so minor changes year to year in order to meet that. For GM, the most obvious are AFM, and auto stop/start.
The EPA regulations that caused them to drop all the older very proven designs!
eg 350, 454 engine blocks.
I mostly own Ford/Toyota products now, got rid of my GM crap.
No more Democrat Detroit Motown crap.
I generally only buy used cars at least ten years old,
so they have a track record.
you can buy a lot of customization and repair for the price of one EPA sanctioned POS politically correct vehicle!
I own:
Ford Expedition, Ford Explorer, Mazda PU , Toyota 4 runner.
All made in America, All 4WD(I need it here in Hawaii).
