Vehicles Affected: Approximately 700,000 GM SUVs, including model-year 2008-12 Buick Enclaves manufactured between Jan. 3, 2007, and Feb. 29, 2012; 2009-12 Chevrolet Traverses manufactured between July 6, 2008, and Feb. 29, 2012; 2007-12 GMC Acadias manufactured between Sept. 15, 2006, and Feb. 29, 2012; and 2007-10 Saturn Outlooks manufactured between Aug. 17, 2006, and March 18, 2010
The Problem: The affected vehicles are equipped with the optional power liftgate and have gas struts that hold the liftgate up when open; these struts may prematurely wear, and the open liftgate may suddenly fail, possibly striking a person and increasing the risk of an injury.
The Fix: Dealers will update the software for the power liftgate actuator motor control unit so that the motor will prevent the rapid closing of the liftgate; work will be done for free.
