The front turn signals are equipped with two bulbs on each side. If one bulb fails, the driver would not be made aware of the loss of light function, which could create a safety hazard. Dealers will update the body control module software free of charge to resolve the concern.
General Motors notified owners of affected vehicles starting in August 2014. You can check with your dealer to see if your vehicle is involved in this program. It is helpful to have your VIN (Vehicle Identification Number) on hand when you contact them. The General Motors recall number is 12212.

If the driver is not aware that a turn signal is not functioning properly, the driver may continue to drive the vehicle. If half of a front turn signal is not illuminating, other driver's may not be aware that the affected vehicle is turning, thereby increasing the risk of a crash.
