DETROIT, Jan 11 (Reuters) - Ford Motor Co said on Monday it will close its three plants in Brazil this year and take pre-tax charges of about $4.1 billion as the COVID-19 pandemic amplified the company’s under use of its manufacturing capacity. Production will cease immediately at Ford’s plants in Camaçari and Taubaté, with some parts production continuing for a few months to support inventories for aftermarket sales. The Troller plant in Horizonte, Brazil, will continue to operate until the fourth quarter.
