Newer engine longevity designs are in question in this video, is he right?

It's not just a theory, they are absolutely designed to deteriorate. My plane was built in 1971. Repainted in 1981. Sure, I've spent time overhauling mechanical parts but the structure is unmolested. Cars rot away, the metals, the plastics, the rubber, the wiring.

I have a 2017 Jaguar F-Type. The plastic was cracking when I purchased it 4 years ago. The gas cap rotted away, the headlights attachment tabs decided to evaporate, the parts inside the door failed. All known problems. Even the shock bushings revert to their native state of dust within a few years. My 2009 F150, while a beautiful truck, had the exact same set of problems. Every plastic electrical connector lock tab rotted off under the hood. And on and on.

Beautiful !!! You're an A&P ?

Seems to be 20wt oils, direct injection (fuel dilution) and very optimistic OCIs.
Remove one or 2 of those and the problem goes away.

I blame H1-B "engineers". I bet most of them never even owned a car before they came to the US and don't understand the ramifications of their questionable engine designs.

Highly doubt it.

There are great and bad engineers in all sorts of places but the problem with companies only hire the cheapest and are about to go out of business can't attract good engineers regardless. You do get what you pay for and when you are struggling that leads to downward spiral. I've had the best and the worst people hired on both camps.

Except that "Planned Obsolescence" and cutting corners to the point of cutting durability and dependability are definitely not "mistakes"

Planned obsolescence only work if:

1) You and all your competitors in a cartel do it together.

or

2) Your customers don't care, they don't want a car to last 20 years and only want a status symbol every 5 years. There is no good resell value difference to justify lasting an extra 15 years.

I think if Toyota cut corners it would be 1 and if Hyundai and Nissan cut corner it would be 2. Hyundai is in no position to cut corner without people complaining about them, they are too far away from the norm today and they will be the one standing out as being bad.

I don't know or don't care if Hyundai's problem is their metal choice, but the bucks stop with their quality control letting that slip and they are at fault regardless of cause.
