Tesla just announced that it is shutting down production of the Model 3 for six days. According to Autoblog:
Tesla has been struggling to find solutions to manufacturing bottlenecks on the new assembly line that produces the Model 3, a sedan intended for volume production. An over-reliance on robots has complicated that task, Chief Executive Officer Elon Musk has acknowledged.
In a long memo published in Electrek, Musk explains that he has had trouble feeding the machine, blaming the complexity of the supply chain.
