General Motors CEO Mary Barra speaks to the news media June 12, 2018 in Detroit, Michigan.

General Motors warned Friday that another wave of tariffs being considered by the Trump administration could force the company to scale back its business and cost American jobs.

In comments submitted to the Commerce Department, the automaker said that the tariffs, if approved, could drive individual vehicle prices up thousands of dollars, stifling demand. Such costs would need to be borne either by consumers or the company.
