That's the least of their problems. Savvy owners will replace and trade in well before that. Materials and sealing are quite good these days, look at your phone for instance. Few will blame the manufacturer for such wear and tear.

Electricity grid and power line capacity issues are still mostly a gleam in the eyes of engineers. Charging must eventually be controlled by the grid, because no power grid can survive a mass charging. (Oh, lemme charge my EV while I watch ManU. Like everyone else on the street. Then of course the grid will trip.)

Public charging when everyone has an EV? That will be like those in line filling up with natural gas. Battery tech is unsolved, no matter what safety measures they put in the pack. Want your new car to burn down your house? Say no more:

What will happen to dense car parks, or condo car parks? Like this:

There was a large garage fire in Norway first tied to EVs, but that was a diesel Opel (had owner as witness, so probably cannot be disputed.) Car makers that talk of going 100% electric are just wanking in public. They are not talking about the problems that will appear.
