NHTSA recall 13V010000

What's wrong: It may be possible to remove the key from the ignition when the vehicle is running or the transmission is not in the park position. As such, these vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard 114, "theft protection."

Why it matters: If the ignition key is removed while the vehicle is still on and/or the vehicle is not in park, the vehicle may rollaway and the unintended movement of the vehicle may result in a possible crash or injury to pedestrians.

The fix: Gm will notify owners, and dealers will replace the ignition lock cylinder and the two associated keys. This service will be performed free of charge. The recall began on February 8, 2013. For more information, GMC owners may call 1-866-996-9463 and Chevrolet owners may call 1-800-630-2438.
