2012 GMC Acadia Recalls
The power liftgate may fall suddenly from the open position due to the failure of the struts that support it when open. Dealers will update the software for the liftgate actuator motor control unit to prevent rapid closing of the liftgate free of charge to resolve the problem.
In the affected vehicles, there is a flexible steel steel cable that connects the seatbelt buckle to the front seat frame. Over time the cable may fatigue and separate. If the steel cable separates, the seatbelt may not properly restrain the seat occupant, increasing the risk of an injury in a crash. Dealers will inspect and replace the affected seatbelt buckles (lap pretensioners) to correct this concern.
Increased resistance in the front seat mounted side impact air bag (SIAB) wiring harness can result in the SIAB and seat belt pretensioners not deploying as expected in the event of a crash, increasing the risk of personal injury. Dealers will replace the affected harness connections with soldered connections to correct this concern.
