(January 23, 2010) DETROIT -- General Motors, continuing to fight vehicle shortages at dealerships, will add overtime production to its truck-based SUV plant in Arlington, Texas, starting next week, according to Automotive News.

The plant makes standard and hybrid versions of the Cadillac Escalade, Chevrolet Tahoe and GMC Yukon. As of Jan. 1, all versions of those SUVs had less than a 34-day supply, according to the Automotive News Data Center. Analysts recommend a 60-day supply, and the overall industry started 2010 with a 53-day supply.

GM told Arlington employees Wednesday that it would add two 10-hour shifts of overtime each Friday starting a week from today, GM spokesman Chris Lee said. The overtime will continue through April, he said. The plant has been running four days a week with two 10-hour shifts each day, to save money by not operating on Fridays.

In addition, the factory will run on two Saturdays in March and two in April.
