Opened the lift gate with the key fob, made a loud noise when fully extended and immediately started shutting while I was getting something out of the back. Don't know if the door would have bounced back up if it hit me and would have started coming back down again since it doesn't stay up. Used manual mode and door does not stay up. Googled it and apparently there have been problems since 2007 with the power lift gate in the Saturn outlook, acadia, Traverse, enclave, and equinox.
