Tesla does plenty of recalls in the states, they just aren’t broadcasted as widely and proudly as they are on CCTV.
It could be that the Shanghai factory is more well run, or it could get experience from the other factories, the model 3 is just 7 years old and before that Tesla was doing more small scale production.
But historically Chinese produced cars are worse than those made in other countries. Toyota, for example, has huge quality problems in China that it didn’t have in US or Japanese produced cars. It would be cool if it is the opposite for Tesla.
