Tesla will cut 7 percent of its workforce as it tries to lower prices and break out of the niche-car market to produce an electric vehicle that more people can afford.
Tesla's cheapest model right now is the $US44,000 Model 3, and it needs to broaden its customer base to survive.
"Looking ahead at our mission of accelerating the advent of sustainable transport and energy, which is important for all life on Earth, we face an extremely difficult challenge: making our cars, batteries and solar products cost-competitive with fossil fuels," CEO Elon Musk said in a letter to staff.
"While we have made great progress, our products are still too expensive for most people."
Tesla had boosted its payroll significantly to meet production goals, but then cut its staff by 9 percent in June.
The company delivered more than 245,000 electric cars and SUVs last year, nearly as many as all previous years combined. But it still fell far short of a goal set nearly three years ago of manufacturing 500,000 vehicles for the year.
Musk said in October that Tesla Inc., based in Palo Alto, California, had 45,000 employees. The 7 percent cut would mean that about 3,150 people will lose their jobs.
Tesla posted a $US311 million quarterly profit in October, only its third profitable quarter in eight years as a public company.
Musk acknowledged that the profit was driven by its ability to sell higher priced vehicles in North America. Tesla dominates that market, but it wants to make electric vehicles for the masses.
And while preliminary numbers indicate another profitable quarter ahead, Musk said it appears to be a smaller. Shares tumbled 11 percent today.
It has been Tesla's long-held goal to get a less-expensive, mid-range Tesla Model 3 on the road.
"Starting around May, we will need to deliver at least the mid-range Model 3 variant in all markets, as we need to reach more customers who can afford our vehicles," Musk said in the letter.
The key for Tesla is producing an entry-level car in the mid-$US30,000 range, which would put it in direct competition with major automakers.
Even as Tesla struggles to produce a more mainstream vehicle, many industry analysts still see the company as the one to beat, even with the world's biggest automakers now fully engaged in the pursuit of an electric car.
