General Motors (GM) has announced that due to auto parts shortages, caused by the disasters in Japan, they will have to shut down some production in the United States.

A GM plant in Louisiana is the first to be closed, for a week, as a result.

Toyota had announced that it would slow production in its U.S. factories. Officials say production will not be affected at their engine plants. Instead of closing plants altogether, Toyota has eliminated overtime work.

Ford says so far their U.S. operations are not affected, Honda said the same thing.
