General Motors is the first automotive industry company to stop production at a United States-based factory due to shortage of materials in the aftermath of the earthquake and tsunami in Japan.

The carmaker hasn’t released what parts are in short supply, but its plant in Shreveport, Louisiana, in the only North American plant to stop production because of the tragedy in Japan.

GM manufactures the GMC Canyon and Chevrolet Colorado pick-up trucks in its Louisiana plant, which employs 800 workers.

Japanese firms Toyota and Subaru have slowed but not stopped production in their U.S plants to conserve the parts stocks.
