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.

These vehicles are being recalled because the weight on the key ring and/or a jarring event while driving may cause the ignition switch to move out of the run position, turning off the engine. If the key is not in the run position, the air bags may not deploy in the event of a crash, increasing the risk of injury. Dealers will replace the ignition switch to correct this concern.

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.
