Apparently this has been a common issue (though usually undetermined failure) over the years, with some reports and speculation on the cause on this site I see, as well. Most would assume age killed the console, or that it was on its way out before being put in storage. Over the years it doesn't seem like anyone here, on Reddit, or elsewhere, knew what the cause was.

Well, it's due to the NAND chip dying. The most common cause is not being powered on often enough.
Worst part? Even if you had the tools and the know-how to swap out that NAND chip... There's a report on Reddit that the NAND is actually "married to the console". Yes, you read that right. The system already plagued with more hardware pairing and DRM than an Apple device might have the NAND bonded to each console.
To be fair I am not sure where that is coming from. There is a thread on this site of someone replacing the eMMC with an SD card and it working, although with much trouble. It could be that an actual eMMC replacement does not work but other methods, like his use of an SD card, do.
I'm a massive advocate of right-to-repair and in general cutting down on e-waste. Electronics will be around long after we aren't. I've disliked the Wii U immensely ever since it came out and we knew how awfully the tablet was handled (that it's bonded to the console with no replacing it or anything about it without getting a new console). This is just disgusting.
