Recalls for the 2011 GMC Acadia: 5
The side curtain air bags may not be properly attached. Unsecured side curtain air bags may not perform as intended, increasing the risk of injury.
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. If the open liftgate unexpectedly falls, it may strike a person, increasing their risk of injury.
In the affected vehicles, the flexible steel cable that connects the seatbelt to the front outboard seating positions may fatigue and separate over time. If the steel cable becomes fatigued and separates, the seatbelt may not properly restrain the seat occupant increasing the risk of an injury in a crash.
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. 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.
Snow or ice buildup on the windshield or on the wiper may restrict the movement of the wiper arm, causing the wiper arm to loosen and cause the wiper to become inoperative. If this occurs, driver visibility could be reduced, increasing the risk of a crash.
