2008 Pontiac G5 RecallsIgnition Lock Cylinder Concern
In order to help prevent rollaway type accidents, all late model vehicles are designed so that the transmission must be in park (or reverse for a manual transmission) before the ignition switch can be turned to the "off" position and the key removed. These vehicles are being recalled because the key can be removed when the ignition is not in the "off" position, increasing the risk of a rollaway type accident. Dealers will inspect the vehicle and replace the ignition lock cylinder as necessary. 2 new keys will also be supplied and programmed as required.
Certain vehicles originally sold in, or currently registered in, the states of Arkansas, Arizona, California, Nevada, Oklahoma, or Texas are being recalled because the plastic supply or return port on the fuel pump module may crack, resulting in a fuel leak. Fuel leakage in the presence of an ignition source may result in a fire. Dealers will replace the fuel pump module to correct this concern. The General Motors recall number is 12190.
The driver may experience a sudden loss of power steering assist. If power steering assist is lost, it would require greater driver effort to steer the vehicle at low speeds, increasing the risk of a crash. Dealers will replace the electric power steering motor to correct this concern. This recall is being implemented on a rolling basis beginning March 29, 2010 trough November of 2010. The General Motors recall number is 10023.
