Tesla appears to be working on improving the speed of repairs: https://electrek.co/2017/03/10/tesla-body-shops-network/

I understand that quality control, including fit and finish, has been steadily improving.

An electric car such as the Model S has some intrinsic advantages over ICE cars in reliability in that the drive system is small and relatively uncomplicated. I think there is likely some bias in the perception of Tesla's reliability in that there is a great deal of attention on the company so problems, no matter how small, are more likely to be reported and commented upon than with more established car makers.

There are a few specific examples that I'm aware of. For example the Model S pop-out door handle was redesigned and has been steadily replaced, and the Model X doors had no end of problems until they apparently sorted them out.
