This recall is serious but hardly means that Honda or any manufacturer that issues a recall is a bad brand. https://www.usatoday.com/story/money/cars/2023/11/17/honda-recall-acura-pilot-ridgeline-odyssey/71617360007/

There’s a lot to engine design, and something as relatively simple as bearings requires advanced knowledge in tribology and fluid dynamics.
You can design for a certain oil with a certain dilution rate but if the oil standards change or the real-world dilution rate is different, you may have failures due to cavitation. You can design for a certain dynamic clearance but if someone else changes the rod bolt spec or something as “simple” as thread fit changes, you may have failures.
Then there are things like manufacturer errors in fatigue strength or embedability or conformability, things that can only be known with a strict quality control regimen.
Thanks for clearing this out.
I figured there would still be enough documentation through previous engine generations (J series V6 engines have been built and upgraded since 1996) to have the main issues and main limits figured out for their purpose (fuel efficient urban driving and urban/crossover levels of towing capacity). Basically it would be fully optimised by then and only be tweaked around knowing anything else pushes the failure rate.
