I really, really, wish somebody would actually put together a real reliability report. You know, by actually getting hard data on what repairs different models need, how often different models break down, how long different models last, etc. That's how you should rate reliability.
The consumer reports model of just surveying a random collection of people about what they personally think about the reliability of cars is not hard data. They don't collect any data themselves. They just take random people's beliefs as the data. It's also an oroborous, as what they rate as reliable/unreliable one year will then influence what people's beliefs are when they're surveyed the next year about what they believe is reliable.

They did it in Germany : https://www.autoblog.com/news/the-bestselling-tesla-model-y-...
But it's based on German made models
Afaik No, German report just lists passed/flagged TUV. TUV fails you on negligence like not servicing car every year like a good VW German owner.
It does not require that, though obviously a car which is never serviced is more likely to fail.
