Hatchback/liftgate Support Device Problems of GMC Terrain

While parked in my driveway. The automatic liftgate goes up and then falls halfway, goes up an then falls back all the way down. It hit me an knocked me own the first time. It started in July of this year and does it consistently. I could have been seriously hurt or a child could even be crushed as it is extremely heavy. I cannot use the rear compartment as the liftgate will not stay open. There is a lawsuit on certain years for this very problem and GMC has a TSB up through 2014 but for some reason the 2015 model is not include even though it has the exact same issue. Here is a video of the issue. This is another Terrain as I don't know how to get a video of mine on youtube. . Read more...

Noticed black fluid on liftgate frame. Several days later I had great difficulty raising the hatch. When I released it the gate fell violentely injuring my hand. It appears both pistons failed. My concern is that had the gate been in the raised position and it fell, myself or a family member would have been seriously hurt. This is very dangerous. The gate is extremely heavy. My dealer did not recognize the urgency of this problem now making me wait nearly a week for repair. Vehicle was parked in my drive at the time.

When trying to open the rear liftgate the door will open completely then quickly close halfway, open completely again, then quickly close shut making it impossible to safely put anything into or remove from the trunk of the car. There is a recall for this issue on the acadia's already.

After being opened, rear power liftgate suddenly falls, drops 3/4 of the way down, comes back up to full height, drops again all the way down, and then the door closes. Vehicle was stationary and parked in the driveway as I was getting my dog out of the back of the vehicle.
