GENERAL MOTORS issued a recall on the IMPALA model

On certain Chevrolet Impala police vehicles, the front control arms may fracture. If this occurs, some tire "squeal" or "chirping" may be heard when turning at low speeds. Sudden changes could occur in vehicle handling and, particularly at higher speeds, the driver may not be able to control the vehicle and a crash could occur, which may result in personal injury and/or property damage. Correction: Dealers will replace both control arms.
