Something like this needs to be taken with in context -
This year, most vehicle problems stemmed from voice recognition, poor-shifting transmissions and failing batteries.
This is wildly different than having a blown engine, having a wheel fall off, or having the wipers break.
The voice recognition and infotainment systems in general are problematic for all auto makers and they don't strand one out in the desert or up in the mountains (like my Ford Exploder did when the transfer case broke internally). This isn't a reliability data point where something initially worked but then broke, but one of functionality.
The 'poor shifting transmission' is somewhat subjective, since what feels terrible to one driver might feel fine to another, and not quite the same as a transmission actually breaking, i.e. reliability. It's a behavior aspect rather than reliability.
The failing batteries can affect any vehicle since there are only a handful of battery manufacturers but there is a potential issue if the manufacturer doesn't specify an adequate battery that can handle the increased electrical demands of vehicles nowadays.
I blindly clicked on that link without seeing it was JD Power - one of the poorest designed and annoying websites on the internet thanks to all of it's various popups and busy-ness.
