Problem: General Motors LLC (GM) is recalling certain model year 2008-2012 Buick Enclave vehicles manufactured January 3, 2007, to February 29, 2012, 2009-2012 Chevrolet Traverse vehicles manufactured July 6, 2008, to March 9, 2012, 2007-2012 GMC Acadia vehicles manufactured September 15, 2006, to February 29, 2012, and 2007-2010 Saturn Outlook vehicles manufactured August 17, 2006, to March 18, 2010. The affected vehicles, equipped with the power liftgate option, have gas struts that hold the power liftgate up when open. These struts may prematurely wear and the open liftgate may suddenly fall.

Risk: If the open liftgate unexpectedly falls, it may strike a person, increasing their risk of injury.

Fix: GM will notify owners, and dealers will update the software for the power liftgate actuator motor control unit so that the motor will prevent the rapid closing of the lift gate, free of charge. The recall began on November 15, 2016. Owners may contact Buick customer service at 1-800-521-7300, Chevrolet customer service at 1-800-222-1020, GMC customer service at 1-800-462-8782, and Saturn customer service at 1-800-553-6000. GM's number for this recall is 15240.
