Shortages could slow down US auto production

The U.S. auto industry is facing two serious
problems that could limit the number of new vehicles in showrooms
later this year.
The most immediate problem is a shortage of a plastic resin used
to make fuel lines and other parts. Last month, an explosion
knocked out a plant in Germany that makes the substance. That could
cause auto assembly plants to slow down in a few weeks.
And if sales of cars and trucks continue to grow, the industry
could run short of parts later this year because there aren't
enough factories to make them. The parts industry shrank during the
recession and hasn't grown enough to handle rising sales.
