Most internal combustion engines are only good for ~200,000 miles, even with excellent maintenance. A worn-out engine is good only for scrap, but an EV battery pack with 50% capacity is still very useful as a solar storage battery.
Most of the 2011 Nissan Leafs are still going strong with ~80% capacity. Their outright failure rate is less than 0.02%. Cell and battery pack technology has improved dramatically since then, so I'd be very optimistic about the useful lifespan of a brand new Model S or Chevy Bolt.
