2012 Chevrolet Impala RecallsIgnition Lock Cylinder Concern
Excess weight on the key ring can cause the ignition switch to move out of the run position without warning, turning off the engine. This defect can also affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. Dealers will install two 13mm key rings and key insert into the vehicle's ignition keys to correct this concern.
On vehicles equipped with the "police" option package, one or both of the front lower control arms may fracture. A broken control arm can result in the loss of control of the vehicle, increasing the risk of a crash. Dealers will replace both front lower control arms to correct this concern. The General Motors recall number is 12104.
The upper power steering hose may be misrouted, causing it to be damaged from the heat of the catalytic converter. Power steering fluid may leak onto the catalytic converter, resulting in an engine compartment fire. Dealers will inspect the upper power steering hose routing and make the necessary repairs to correct this concern. The General Motors recall number is 11224.
