“Automakers have been making hybrids long enough that they’ve gotten really good at it. Plus, many hybrids are also made by manufacturers that tend to produce reliable vehicles overall, such as Toyota, Hyundai, and Kia.”

It's anti-intuitive that hybrids would be more reliable than pure ICE cars. But it would be explained by this if hybrids are somewhat less reliable than the ICE cars from these three makers. Presumably Consumer Reports has that data ...

For the big picture you need to compare the relative reliability of components after X million have been built. I would be surprised if the reliability of EV tech hasn't improved faster just because it has developed more recently.
