Tesla Model 3 production was halted in the last week of February to allow the company time to fix automation issues and address bottlenecks.
The car maker said the production freeze, which took place from the 20 to 24 February, would now enable it to ramp up production to 2500 cars per week by the end of March.
Prior to the production halt, Tesla employees were said to be making batteries by hand in a bid to face growing a demand backlog. An unnamed inside source told CNBC that Tesla had been "borrowing" workers from Panasonic, with which it is partenered, to speed up production. They said quality control workers were also not experienced enough to ensure the job was done well enough.
But a Tesla spokesman responded by stating that the company had expected some parts of the production process to require "manual" work at that stage. "This is something Elon Musk [CEO] and Jeffrey Brian Straubel [CTO] discussed extensively on our Q3 earnings call, and it has no impact on the quality or safety of the batteries we"re producing," they said.
