In the US*

In the rest of the world, with Korean-produced vehicles, they do much better

GM hos long had the same. Even in cases where GM has had toyota put a GM name on a car the GM is rated 3 stars and the Toyota name is rated 5. thus I put little weight on rattings

Anecdote but I've been super happy with my 2010 Santa Fe. It's at 135k miles and has had zero issues with the drivetrain. In fact literally the only problem with the car after 15 years is that one of the passenger doors no longer automatically locks.

I sometimes tell myself maybe I should buy an EV, but then realize I can drive this thing for another 50k miles, which I'll probably end up doing.

I had a car with a Hyundai engine. We loved that car. Unfortunately, we did not love the engine. At only 90k miles, it started burning 1 quart of oil every 1000 miles.

I want to be clear that I know what I'm doing around cars and an meticulous with regular maintenance, so this wasn't caused by neglect.

Doing some research online, it turns out this happens to pretty much all of them at some point after the warranty is up. There is also a separate issue with these engines where they randomly grenade themselves which caused a class action lawsuit.

These issues are so common that you simply cannot buy a replacement engine from Hyundai, because there are no more left. There are remanufactured ones available, but they cost more than the car is likely worth, even before labor.

All my cars are Honda or Toyota from now on.

This. Current generation has failing ICCU's at staggering numbers. They replace them but haven't confirmed they fixed design issues. At least $2-3k.

Older ones (Kona) has reduction gear with some design flaw and Hyundai recommend changing its oil. Aaaaand it fails right at around 100k when most warranties lapse (cleverly their 8yr warranty is only for battery - likely most reliable component).

Bonus: just seen today Mercedes EQS has a motor seal design issue that at around 120kkm causes coolant intrusion. Tesla had same issue, but at least it was permanently fixable (aka coolant delete).
