Early Model 3/Ys built in the US were unreliable. The ones built in Shanghai, though, are excellent. Berlin is somewhere in the middle.

FWIW, I'm into my fourth year of (Chinese-built) Model 3 ownership and it's been rock solid, the only services so far were to replace the air filter and wipers.

Kind of a silly question but I want to be sure I’m piecing together a fair picture: both of those are five minute tasks you do yourself outside the auto parts store / driveway, right?
