I'm sure They're reliably, but like any car, anything can go wrong with them. That's why historically a Toyota is much more reliable than a Buick. Its not written down in a spec sheet. It is how well does it do in the real world. I made my original comment because i personally know someone who's electric car died one week past the standard warranty.
