NHTSA recall 12V484000

What's wrong: These vehicles are equipped with two turn signal bulbs in each front turn signal. If one of the two front turn signal bulbs burn out in either front turn signal lamp, there is no indication to the driver. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard no. 108, "lamps, reflective devices, and associated equipment."

Why it matters: 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.

The fix: Gm will notify owners, dealers will update the body control module software, free of charge. The recall began in September 2014.
