Tailgate falls down after opening. Will not stay up without holding.
As my GMC Acadia is sitting in the garage I pulled on the lift gate handle to open the tailgate. Confidence that it was good to step in an put my baby's stroller I proceeded to step in as soon as the lift gate got to it's peek the strut gave in and the gate came down about two feet or so striking me on top of my head. I managed get down as to not get heart the lift gate seems to be out of service because there is no way to open it and have it stay open. It jerks and then it closes itself.
