DETROIT (AP) — General Motors is recalling more than 38,000 Chevrolet Impala police cars because a part in the front suspension can fracture and could cause a crash.

The company says in government documents that the recall affects police cars from the 2008 through 2012 model years. GM says Impalas sold to the public have different suspension parts and are not affected.

GM says the front lower control arm can fracture. That could cause sudden changes in handling, and the driver may not be able to control the car, particularly at high speeds.

Company spokesman Alan Adler says GM doesn't know of any crashes or injuries from the problem. He says parts are available, and police departments should call dealers to schedule repairs.

The cars were sold in the U.S. and Canada.
