Model years: 2011

Problem: General Motors LLC (GM) is recalling certain model year 2016-2017 Buick Verano and 2016 Chevrolet Malibu as the electronic park lock lever may allow the ignition key to be removed without the transmission being in PARK. Also, certain 2013 Buick Encore, 2011 Buick Regal, 2013-2014 Buick Verano, 2011-2016 Chevrolet Cruze, 2010-2013 Chevrolet Equinox 2013-2015 Chevrolet Malibu, and 2011-2013 GMC Terrain vehicles may have been serviced with similar defective replacement electronic park lock levers. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 114, "Theft Protection and Rollaway Prevention."

Risk: If the key is removed without the transmission in PARK, the vehicle may rollaway as occupants are exiting, increasing the risk of injury.

Fix: GM will notify owners, and dealers will inspect and if necessary replace the key cylinder lock housing, free of charge. The recall began on October 14, 2016. Owners may contact Chevrolet customer service at 1-800-222-1020, Buick 1-800-521-7300, and GMC 1-800-462-8782. GM's number for this recall is 50490 and 50491.

Power train:automatic transmissionFeb 21, 2014 · NHTSA campaign 14V092000 · 355 vehicles

Model years: 2014

Problem: General Motors LLC (GM) is recalling certain model year 2014 Buick Regal, LaCrosse, Verano, and Enclave, and Chevrolet Impala, Malibu, Cruze, and Traverse, and GMC Acadia vehicles equipped with automatic transmissions. In the affected vehicles, the transmission shift cable adjuster may disengage from the transmission shift lever. As such, these vehicles do not conform to Federal Motor Vehicle Safety Standard (FMVSS) number 102, "Transmission Shift Lever Sequence, Starter Interlock, and Transmission Braking Effect." They also fail to conform to FMVSS number 114, "Theft Protection and Rollaway Prevention."

Risk: If a vehicle's shift cable disengages from the transmission shift lever, a driver may be unable to shift gear positions and the indicated shift position may not represent the gear position the vehicle is in. Should a disengagement occur while the vehicle is being driven, when the driver goes to stop and park the vehicle, the driver may be able to shift the lever to the "PARK" position, but the vehicle transmission may not be in the "PARK" gear position. If the vehicle is not in the "PARK" position there is a risk the vehicle will roll away as the driver and other occupants exit the vehicle or anytime thereafter. A vehicle rollaway increases the risk of injury to exiting occupants and bystanders.

Fix: General Motors will notify owners, and dealers will inspect and replace any affected transmission shift cable adjusters, free of charge. The recall began on April 10, 2014. Chevrolet owners may contact General Motors at 1-800-222-1020, Buick owners at 1-800-521-7300, and GMC owners at 1-800-462-8782. General Motors' number associated with this recall is 14048.
