Does Tesla have a Quality Control issue what is the measure?
While I see plenty of delivery experience horror stories on social media, I would call those anecdotes and not real data unless they were measured appropriately against other brands.
The "JD Power Initial Quality Survey" has been debunked by Tesla Daily Podcast as a poor measure of "initial quality" and they are measuring something different.
Consumer Reports has the Model X as one of the least reliable cars in 2020. They are probably a better measure, but I have not seen a critique of how they measure quality/reliability.
