I mean, we really haven't had enough EVs (not mixed, like a Prius) on the road for long enough to make that call. It's possible, but 10+ year battery fail rates, water issues, or other unanticipated issues may over-ride simplicity.
For example: On early Priuses, the regenerative braking would be used so much that the 'real' brakes would calcify/glaze over. When an hard stop was needed (emergency, got cut off, etc) then the 'real' brakes would not work as intended. Many of the early Priuses have front-end damage as a result. It took them about 4 years to fix it.
