A fire broke out at Tesla's Fremont factory in California on Thursday afternoon.

As spotted by CNBC, the Fremont Fire Department said on Facebook that firefighters responded to a "working fire" at the factory at 4:27 p.m. on Thursday.

The fire was caused by "molten aluminum and hydraulic fluid," it said.

"Located in an area of the factory property that is under construction, the deep-seated fire was contained to a vehicle manufacturing stamping machine," the department said in its statement.

It said there were no reports of injuries to any Tesla staff or Fremont firefighters.

At the time of its statement, the Fremont Fire Department said the fire was "under control" and it had left two fire engines plus a truck on-site to monitor it. It also added Tesla's fire response helped to control the fire.

This isn't the first time a fire has broken out at the factory. In 2019 firefighters were able to quickly contain a fire at the site, again with no injuries.

CNBC reported in 2018 the factory's paint shop had experienced four fires in four years.

Tesla's Fremont factory was shut down for two days at the end of last month due to a parts shortage, CEO Elon Musk said.
