An anonymous reader quotes a report from The Wall Street Journal (Warning: source may be paywalled; alternative source): Tesla badly missed its goal of building 1,500 Model 3 cars in the third quarter, the first sign that the production ramp-up for the new sedan isn't going as smoothly as planned. The Silicon Valley electric-car maker built 260 of the Model 3s between July and September, the company said Monday in a statement. In August, the auto maker predicted it would build more than 1,500 Model 3s before cranking up production to 5,000 a week by the end of the fourth quarter. Tesla blamed "production bottlenecks" for the weaker production. "It is important to emphasize that there are no fundamental issues with the Model 3 production or supply chain," Tesla said in a statement. "We understand what needs to be fixed and we are confident of addressing the manufacturing bottleneck issues in the near-term."
