Recalls (4)
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.
