So you’re just going to ignore data that says something opposite to your preconceived notions about how stuff works? In that case, I’ve brought you a nice box of sand for your head.
It is surprising that EVs are not as reliable as one would expect, but then again, we have way more experience building internal combustion engines than we do EV components.
Consumer Reports publishes their methodology for collecting this reliability data. It’s not difficult to find. It’s not a black box.
I’m in the market for a new EV, so I checked out Consumer Reports reliability data for the models I was looking at. They break it down based on 20 areas (engine, electronics, infotainment, build quality, etc.) and provide reliability for each of those areas. And those areas are not weighted the same. Most of the reliability issues with the EVs I looked at are with electronics (presumably charger related) and drive train issues.
But despite that, CR still recommends a number of EVs, even ones with meh reliability. Fossil fuel good ol’ boys my ass.
