The endgate/liftgate can be locked or unlocked by operating either one of the front door lock switches, your's doesn't do this ?
Endgate/Liftgate
Once the vehicle doors have been unlocked, the endgate/liftgate can be opened by using the handle mounted to the exterior of the gate. The endgate/liftgate can be locked or unlocked by operating either one of the front door lock switches, or by pressing the Lock/Unlock button on the key fob. The endgate/liftgate lock and unlock functions operate in conjunction with the rear doors.
Hatch or liftgate ? Liftgate Release
The liftgate release switch operates the liftgate latch electronically. When the switch is pressed, the SJB processes the input and releases the liftgate latch.
The doors must be unlocked electronically in order for the SJB to release the liftgate latch. When this condition is met and the SJB receives the input from the liftgate release switch, the SJB provides power to the latch release motor.
SJB - smart junction box , fords BCM - body control module .

Hi, viewers. The liftgate latch of 2008 Acadia is electrically controlled by switches, fuses, modules, and sensors. If for some reason the liftgate doesnt seem to open under the normal operating conditions, you can still open it mechanically if needed.
* First, go inside the vehicle and lower the 2nd and 3rd row seats, and then locate the round access plug (visible and similar to a rubber grommet) from the liftgate lower interior trim panel.
*Second, use a small flatbladed tool to remove that access plug and expose the hole.
*Third, look through the hole and push on a silver lever located on the right to unlock the liftgate.
*Fourth, when unlocked, push the liftgate outward or, you may need an assistant to pull open the liftgate from the outside handle while you push the unlock lever.
Once opened, you can now reflect back as to why your liftgate wont function. I hope you get lucky in your quest. Have a nice day! : )
Unlock the doors with the power unlock button then you have to push in on the bottom part of the plastic bezel that surrounds the liftgate handle, while at the same time pulling the liftgate handle outwards. It should open then.
