RepairPal Expert Overview
Affected vehicles may be shifted out of Park with the ignition key removed or the ignition in the "off" position. As a result, the vehicle may roll unexpectedly, increasing the risk of injury or a crash.
General Motors will notify owners of affected vehicles beginning January 17, 2013. If you find you can move the shifter out of the Park position with the ignition in the off or lock position, or you don't receive notification and you feel you should have, please contact your dealer. It's helpful to have your vehicle identification number (VIN) when you call. The General Motors recall number is 12331.
All late model vehicles are equipped with a "Shift interlock" system that prevents vehicles with and automatic transmission from being shifted out of the Park position under certain conditions. Some of these vehicles are being recalled because they may have been assembled with a broken park lock cable or a malformed steering column lock actuator gear. Failure of these components can allow the shifter to be moved out of the Park position with the ignition key removed or in the off position. This can cause the vehicle to roll away unexpectedly increasing the risk of injury or a crash. Dealers will inspect the recalled vehicles and replace the steering column as necessary.
