My ICE car (same price range of the Tesla 3 and Y) had so many issues that make me consider to change it more than a couple of times, so maybe you at least need to not be unlucky.
What I agree with you is that, normally, a 60k $ car from an well-established brand is way less prone to have quality issues than a car in the same prince range from a brand that 20 years ago did not even exist but I am sure enough that if we look at the same number of 60k $ cars from other brand with the same thoroughness we use to find defects in a Tesla, we probably will end up with roughly the same number of defects.
