In Which magazine, EVs were about as reliable as normal cars, however if you removed tesla from the ratings, then EV reliability jumped significantly to way above standard petrol/diesel. https://www.which.co.uk/ has the details, but you need to be a member to find out. Basically the fit, finish and reliability of the accessories were trash.
I've seen the argument that "traditional auto makers" don't "get" how many people think - they concentrate on panel gaps or wind noise or door closing bump noise. Tesla isn't great there, but the Tesla software is good, and what some people call "kids" treat the car more like a smart phone. They don't care if your panel gaps are great - if your infotainment software is very laggy or crashes, it's a low quality car.
I've seen many auto manufacturers go under over the course of my life. Tesla is just going to be another one.
