This excellence did not come without its share of challenges early on. Model X is a complex vehicle to build, and its advanced feature set introduced some obstacles as we ramped production in early 2016. In the months since, we have introduced significant updates to make Model X an even better car. Most of these refinements have rolled out as over-the-air software updates, which enhance each vehicle regardless of when it was built. For the small number of improvements that are hardware-related, changes have rolled out to our early owners via priority Tesla Service. We have implemented those same changes in our factory immediately, because we do not believe in waiting for the next model year to introduce improvements to our cars.
