Owners/service Manual problems of the 2011 GMC Terrain

Liftgate not working. Access to the back compartment is compromised as the liftgate does not work either using the wireless keys or pressing on the button to manually open the liftgate. The door continuously latches and makes it nearly impossible to open. I have to trick the timing and attempt to pull (using great force) before the liftgate will latch again. Lots of force has to be used as compressed air makes it very difficult to lift and close the back liftgate. Although gm has had nearly 900,000 vehicles recalls with the same problem, I was told my vehicle does not fall in this recall. Please consider my 2011 GMC Terrain as part of this recall, so I can get it repaired. Thank you!.
