What does that say about the "other lines", doesn't give a positive impression at all, Lol.
Unfortunately I have friends with 2017 and 2018 Model S and Model X with a lot more quality issues than my 2014 and 2016 cars. My July 2018 Model 3 "tent" car has been pretty much perfect. Zero service required besides the tiny paint chip and curbed wheel at delivery. Just anecdote though.
