Prior to announcing the cuts, GM had hoped to reduce its workforce through voluntary buyouts offered to 17,700 employees, but the acceptance rate initially was low.
Two people briefed on the cuts said GM is cutting hundreds of jobs at its information technology centres in Texas, Georgia, Arizona and Michigan and more than 1,000 jobs at its Warren, Michigan Tech Center.
The firm will begin notifying employees that they're getting laid off at 7:30 am on Monday morning, but the process of parting with roughly 4,250 workers is expected to take weeks.
Most of the employees who will be part of this round of cuts are responsible for components for internal combustion engines and discontinued auto models.
The company also announced Monday that more than 1,500 USA hourly or blue-collar employees have volunteered to transfer to other locations.
Te overall plan will ultimately cut a total of about 15,000 jobs and end production at five North American plants. It announced plans for an $11 billion restructuring last October and is expected to axe as many as 25,000 jobs, though a majority of those cuts are seen targeting Europe and other financially struggling markets.More news: Iraqi President hits back at Trump over comments on U.S. presence

The company said that about 18,000 non-unionized workers across its North American operations were eligible for the buyout package.
The layoffs were first announced in November, along with plans to close four plants - two in MI, one in OH, and one in Ontario. These include the Chevrolet Cruze, the Cadillac CT6, the Chevrolet Volt hybrid and the Buick LaCrosse.
Trump, who made a 2017 speech near GM's Lordstown Assembly plant in OH, said in November the company had "better" find a new product for that plant.
"All of them are impacted", Rothenberg said.
The automaker also is working with Canadian universities and government officials to assist some 3,000 workers affected by the closure of an Ontario plant, a GM spokesman said.
