Auto sales are growing so fast that Detroit can barely keep up. Three years after the U.S. auto industry nearly collapsed, sales of cars and trucks are surging. Sales could exceed 14 million this year, above last year's 12.8 million.
The result: Carmakers are adding shifts and hiring thousands of workers around the country. Carmakers and parts companies added more than 38,000 jobs last year, with industry employment averaging 717,000 for 2011. And automakers have announced plans to add another 13,000 this year, mostly on night shifts.
But there's a downside. The newfound success is straining the factory network of the Detroit automakers, as well as the companies that make the thousands of parts that go into each vehicle. This could lead to shortages that drive up prices.
