Automakers are cutting 700 jobs as they grapple with the global financial crisis.
But the cuts come as the auto industry is reeling from a sharp drop in orders for new vehicles, including the Chevrolet Bolt, the Ford Focus and the Ford Escape.
In some cases, automakers have already made cuts that are far larger than they announced during the crisis.
Ford said Friday that it will lay off 3,400 workers.
GM said it will shutter 10 assembly plants and reduce its workforce by 10 percent in some cases.
General Motors has said it is slashing 1,200 jobs in the United States and Canada.
Ford, which makes the Ford Fusion, said it would reduce its US production by 10,000 jobs over the next year, with the result that some Fusion vehicles may no longer be sold in the U.S. GM will also lay off 2,200 people at its plant in Indianapolis, Indiana.
GM and General Motors Co. have also said that they are reducing investment in their U.K. plants by about $10 billion in 2019 and 2020.
The auto industry has been grappling with the impact of the global recession on demand, as the number of new vehicles sold in America fell sharply in the years after the financial crisis began in 2008.
In North America, GM and Ford say they are cutting 1,800 jobs.
Ford says it is cutting 2,600.
GM says 1,600 positions will be cut.
Ford also announced it would sell its new Focus SUV to Tesla Motors Inc., a maker of electric cars, and that it would lay off 1,000 workers at its Ford Motor assembly plant in Michigan.
GM is also closing its Detroit Assembly Plant, which is where the Focus, Fusion and Escape are made, and moving production to Mexico.
The cuts come after the company announced plans to cut nearly 800 jobs in 2019 at the Michigan plant and to cut another 700 jobs at its Indianapolis plant.
General Motor Co. also announced plans for a reduction in spending on its Detroit plant, including a $300 million investment to upgrade its diesel engines.
The U.N. International Energy Agency estimates that global demand for diesel is down about 5 percent over the last year, driven in part by the economic crisis.
General GM, which reported its fourth-quarter results on Thursday, also announced that it is shutting down some of its operations in China and is reducing its investment in the country.
In addition, General Motors said it has decided not to renew its lease on its Toledo Assembly Plant.
General said it was closing the plant for the first time since 2007.
The company also said it plans to sell some of the vehicles made by General Motors in Mexico to a local company.
Ford and GM say they will cut 2,400 jobs and cut spending by $10.5 billion in 2020, 2019 and 2018.
GM plans to hire more than 300 people in China in 2019.
Ford plans to shut down its Detroit assembly plant.
GM also announced an investment of $1 billion to help improve the quality of the electric cars it makes.
General announced plans in September to build new battery factories in China, with a total capacity of 50 million batteries.
