Hi TMC According to my factory tour, I have seen two lines, one line to work on Model S, one line which is line 2 is working on Model X. My question to you guys is how is it possible for the robots that were programmed the same way, doing the same tasks to build Model Xs in different quality standards. Some Model X were flawed, problematic with doors, seals, alignment etc. But some are all good to go. I believe there are human intervention in the assembly line that created the difference. But what else? Maybe all Xs have problems, just some owners did not have enough time to catch them or there are perfect Xs been built? But Why? Also problems seem not only apply to earlier Vins, even the most recently Model X deliveries have problems. VIN is now in thousands. Vin does not seem to matter on quality. Feel free to comment below.
