I agree that some cars have problems, though I am skeptical of the "highly overstated" part. I think unhappy buyers tend to be vocal, for sure. But the majority are silent, take their cars, and go on with their lives. Which Tesla's counting on.
I'm starting to think Tesla's management strategy with car quality is "management by luck." They're continuing to count in incredible levels of customer goodwill, generated through the sheer delight and fun of the Tesla driving experience, the look and functionality of the cars, the feeling of being set FREE from the clutches of the oil and gas industry, and the feeling of helping the overall company mission and climate crisis mitigation and the sense of "belonging" with the millions of others who've already taken the plunge, etc. So there's all this goodwill that historically has helped out Tesla with customers overlooking/forgiving quality issues going back to day one.
I agree with others that the Y is still new, and anything new with relatively low VINs may have some issues. Most will be forgiven by new owners, if they even notice them. The detail-oriented, checklist-carrying mavens among us might send the car back, or demand repairs/corrections, and I think this is where the luck factor comes in: Tesla's counting on the number of such send-it-back-and-fix-it demands to be relatively low. If it got really big, then it becomes an Issue. And Tesla is also incentivized, by Wall Street and shareholders in general, to perform well in each quarter, especially in the current Q2 due to the pandemic. All these pressures come bearing down on Tesla and I think the company continues to count on luck with regard to the quality control issues that probably affect a small-to-medium portion the factory's output. Me, personally, I'd raise holy hell if I were Elon and fix the effing QC problems, put new management in place, do whatever it takes. But that's just me.
