Recalls (3)
Structure › Body › Hatchback/Liftgate · Jun 30, 2015
NHTSA campaign 15V415000 · 691,144 vehicles
- 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.
Air Bags › Side/Window · Mar 17, 2014
NHTSA campaign 14V118000 · 1,176,407 vehicles
- Problem
- General Motors LLC (GM) is recalling certain model year 2008-2013 Buick Enclave and GMC Acadia and 2009-2013 Chevrolet Traverse and 2008-2010 Saturn Outlook vehicles. In the affected vehicles, increased resistance in the driver and passenger seat mounted side impact air bag (SIAB) wiring harnesses may result in the SIAB and seat belt pretensioners not deploying in the event of a crash.
- Risk
- Failure of the side impact air bags and seat belt pretensioners to deploy in a crash increase the risk of injury to the driver and front seat occupant.
- Fix
- GM will notify owners, and dealers will replace the affected harness connections with soldered connections, free of charge. The recall began on June 16, 2014. Buick owners may contact the owner center at 1-800-521-7300, Chevrolet owners at 1-866-694-6546, Saturn at 1-800-553-6000, and GMC owners at 1-866-996-9463. GM's number for this recall is 14030. Note: Vehicles repaired as part of Customer Satisfaction Campaign 10085 and special coverage 10335 have already had the subject condition repaired and therefore are not included in the safety recall.
Electrical System · Jun 4, 2010
NHTSA campaign 10V240000 · 1,365,070 vehicles
- Problem
- GM IS RECALLING CERTAIN MODEL YEAR 2006-2009 BUICK, LUCERNE; CADILLAC DTS; HUMMER H2; MODEL YEAR 2008-2009 BUICK ENCLAVE; CADILLAC CTS; MODEL YEAR 2007-2009 CADILLAC ESCALADE, ESCALADE ESV, ESCALADE EXT; CHEVROLET AVALANCHE, SILVERADO, SUBURBAN, TAHOE; GMC ACADIA, SIERRA, YUKON, YUKON XL; SATURN OUTLOOK; AND MODEL YEAR 2009 CHEVROLET TRAVERSE VEHICLES EQUIPPED WITH A HEATED WASHER FLUID SYSTEM (HWFS).

HOWEVER, THERE HAVE BEEN NEW REPORTS OF THERMAL INCIDENTS ON HWFS MODULES AFTER THIS IMPROVEMENT WAS INSTALLED. THESE INCIDENTS RESULTED FROM A NEW FAILURE MODE ATTRIBUTED TO THE DEVICE'S THERMAL PROTECTION FEATURE. THE SIGNIFICANCE VARIES FROM MINOR DISTORTION TO CONSIDERABLE MELTING OF THE PLASTIC AROUND THE HWFS FLUID CHAMBER.
- Risk
- IT IS POSSIBLE FOR THE HEATED WASHER MODULE TO IGNITE AND A FIRE MAY OCCUR.
- Fix
- DEALERS WILL PERMANENTLY DISABLE AND REMOVE THE HEATED WASHER FLUID MODULE. AN UPDATED PAGE FOR THE OWNER MANUAL WILL BE PROVIDED AND INSERTED IN THE OWNER MANUAL TO DOCUMENT THAT THE FEATURE HAS BEEN PERMANENTLY DISABLED AND REMOVED FROM THE VEHICLE.
