I talked to some folks recently who gave some insight into the current state of the Model 3. Most worryingly is some very important components are currently being produced with high failure rates. This is due to design changes (vs Model S) to make manufacturing more economical. Those involved are not showing high confidence that these problems will definitely be solved on time. More positive news is that the internal goal is still July to begin production, although at a lower rate that stated elsewhere (<100 / wk). Overall I have concerns that they will be on time with a reliable product. I am a fan/investor so I am not rooting for this, but wanted to let you know what I heard.
