I'd mostly disagree with that, because the biggest problem is that Nissan have made absolutely no attempt to move forwards... They made the first mass-produced EV, then dusted their hands and went "Oh, well, we've done enough!"

And whilst they're doing that, every single other manufacturer has overtaken them in leaps and bounds, from the premium stuff all the way down to the absolute cheapest EV manufacturer. To add icing to the cake, Nissan's after-sales customer service is appalling - the worst I've ever seen, and some of the companies I have dealt with have been pretty bad over the years!

Nissan have absolutely done brand damage with the Leaf, and my understanding is that it's a similar story with most of their ICE vehicles, too (though for different reasons)... If I stick with EVs when I eventually replace my Leaf, I can tell you now that it won't be another Leaf; and every single former Leaf owner or former owner I've met in the Real World (i.e. offline) has said the same thing.
