Betchya my Dollars against yer doughnuts that if there was a lack of timely oil changes - it was the most salient contributing factor. But I'm posting out of my freshly picked nose here - no amount of preventative maintenance and SuperSILK-2000 hootchy cootchy manly-man-dude oil's going to smooth over a manufacturing issue.
That said, *I* haven't really ever, never seen any Honda power plant lube failure issues stemming from timely, proper by-the-book-oil-changes. Oil. Filter. Change. Repeat. Profit! 🤟
It's the college kid or the elderly mums that pinches pennies and ignores OEM book/OLM/Walmart windshield sticker reminders that run into trouble....? Maybe this one sample is a one in a million or two outliers that left the factory with three of her wheels in the grave?
EDIT: It bears mentioning that this may simply be a middle man problem. I trust that the majority...not all - oil manufacturers that can make product to spec and API guidelines will make a trustworthy product. I also trust that an *EXPERIENCED* auto manufacturer will stand behind their product and put it forth in the best of faith and will to honor a warranty as long as an owner follows reasonable guidelines between the petroleum folks and an upstanding automaker.
It will and seriously, egregiously fall to shambles if the *OWNER* themselves does not take due and proper diligence on their behalf to see to it that their machinery isn't maintained to minimal specifications. I suspect that there is more to this sordid tale.
