Chrysler Group LLC plans to keep open a factory in Sterling Heights, Michigan, just north of Detroit, beyond its planned 2012 closing date, and add nearly 900 jobs in a second shift at the plant. The company is optimistic that consumers will embrace the company's refurbished midsize sedans, the Dodge Avenger and Chrysler Sebring.

In the fall, Chrysler plans to start selling new versions of these cars, which it claims will be updated from top to bottom. The second shift will begin in the first quarter of 2011.

Chrysler CEO Sergio Marchionne told reporters that the Sterling Heights factory, which currently employs 1,270 workers on one shift, would also produce the next-generation Chrysler midsize car that will be built on a new undercarriage.

Parts makers for the Sebring and Avenger, and the Sebring convertible, which also is built at the plant, are expected to add 500 jobs.
