Several days after the earthquake, the parts and components were supplied normally, and the Fourth North American factory resumed production

Four assembly plants in North America were shut down for two weeks after Japan's earthquake caused a shortage of auto parts, US media reported on May 9. After several days of recovery and gradual normalization of supply, General Motors announced that the four North American plants formally resumed production on May 9.

Tom Wickham, a spokesman for GM, said that GM's four major plants in North America: spring mountain assembly plant in Tennessee, Fairfax vehicle plant in Kansas, Rhodes town vehicle plant in Ohio, and Oshawa plant in Ontario, Canada, resumed production on May 9 after being shut down on April 25.

Chunshan factory is producing 2017 Cadillac xt5. Last month, Cadillac's sales in the United States fell 28.9% year-on-year, mainly due to the export of the old SRX and the expansion of xt5 production. The lodeston plant is producing GM's new 2016 Chevrolet Cruz. Oshawa plant is currently responsible for the production of 2016 Chevrolet Malibu.

GM has previously said it does not want temporary plant closures to affect its North American full year product plans or its second quarter 2016 sales. GM did not disclose the affected parts, but workers in lodeston revealed on Facebook that the shutdown was due to a shortage of electrical parts.
