Firefighters responded to a “working fire” at the Tesla plant in Fremont, California, according to a statement from the Fremont Fire Department. 

No personnel or firefighters were injured, writes CNBC.

The fire reportedly occurred in an area of the Tesla facility that is under construction. This is Tesla’s primary U.S. vehicle assembly plant. The company is currently building a second one in Austin, Texas.

Elon Musk’s electric car company makes its Model 3 sedan, Model Y crossover SUV, and higher-end Model S and X electric vehicles in Fremont.

The Fremont plant recently shut down for at least two days due to parts shortages, according to Musk.

The factory has a history of costly fires, including multiple fires at its paint shop, as CNBC has previously reported.

According to Tesla’s fourth quarter filing with the SEC, Tesla has received “notices of violation” from the Bay Area Air Quality Management District relating to air permitting and compliance for the Fremont factory, too.
