GENERAL MOTORS issued a recall on the SIERRA, and SILVERADO models

Certain vehicles may experience a sudden loss of power steering assist that could occur at any time while driving. If the power steering assist is lost, 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 may increase the risk of a crash causing injury and/or property damage. Correction: Dealers will replace the power steering assist motor.
