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).
