GENERAL MOTORS issued a recall on the IMPALA model

Certain vehicles may experience an intermittent or lasting loss or reduction of power steering assist. If the power steering assist is lost or reduced, a message is displayed on the Driver Information Centre and a chime sounds to inform the driver. Steering control can be maintained, as the vehicle will revert to a manual steering mode, but will require greater driver effort particularly at low vehicle speeds. The sudden change in steering effort may increase the risk of a crash causing injury and/or property damage. Correction: Dealers will repair an electrical ground connection at the power steering control module and update software.
