While that is true for some cars, not all cars, EV or ICE, are built equally. One of my previous cars got all the preventative maintainance, but it still started to break down constantly at 120k miles (Saab 9-5 if you’re curious). The issue is that while we have a lot of reliability data for ICE cars, there isn’t much for EVs. Ideally they would have higher reliability since they are relatively more simple, but at this point we do not have long term data.

Also, and this is an article problem, not a you problem, years owned is not as helpful as miles driven. Even in EVs, the slight degradation you see YoY could be amplified by driving 50k miles in a year.
