You will never get any vehicle that is 100% reliable so there’s always the chance of a fault occurring no mater whether EV, ICE or hybrid.
After 3 EVs in 10 years, doing over 150k miles I’ve had one issue, my first Leaf where the 12v battery went flat.
Niggles that annoy me are this one I can’t preheat it unlike my previous 2… First world problems eh?
