If you're referring to what happen to companies like Hertz, then according to them the problem wasn't reliability.
The cars had more accidents, probably because some were not used to the speed or would get an EV just to test the speed. Why buy Tesla in that case then, when their repairs are known to be super expensive and slow? Then you had people who are not used to EVs and charging trying to use EVs and the companies themselves didn't build the charging infrastructure so customers left with a full battery, but that has nothing to do with reliability. Vehicle depreciation? Again, a Tesla problem because they sold them the cars at a high price before dropping prices (the covid years were very weird).
So again, what makes EVs unreliable? It's a simple question.
