This seems almost completely untrue?
The new models have engines that are smaller turbos, that part is true — but they get >30% better fuel economy, and they output more power.
The reliability might become an issue down the road especially in hybrid engines but the data so far don’t seem to support your assertions. The one exception is maybe the Tundra 3.4L but that seems to still be ambiguous as to the root cause, and may just be mfg process error.
I wonder if this notion comes from the 80s, when engines with turbos had lower compression ratios for reliability. Today's turbocharged motors have higher compression ratios than in the malaise era, and the turbos have a lot less lag. Turbos no longer mean you have to sacrifice fuel economy for performance (unless you have a lead foot).
Nope, just engineering to do not much more for warranty. Turbo engines arent inherently unreliable (tho you might need to replace the turbo itself every 100-200k so still more expensive to maintain), just need to build extra strong block and components if you want it to run for a long time.
And why would company do that if that would put it far over warranty period?
This is what toyota marketing says
