Poor quality? I don't think so.
Name any other car manufacturer that makes dozens of improvements to their models mid year. If they drop the ball, it is due to lack of resources and being focused on tasks such as the Model 3 ramp-up that was a bet-the-company operation. Compare a 2014/2015 Model S to a 2018/2019 Model S and you will see all the refinements Tesla has made to make for a better quality experience.
Honestly removing the sunroof is the only thing I am disappointed with the Model S interior. Just about everything else has been improved.
