I opened my power lift gate to load groceries in the trunk. It opened without issue. As I loaded the groceries the lift gate came crashing down on my head. This happened in the festival foods parking lot around 5:05 pm today (7/16/23). Once I moved out from under it I saw the left arm was popped off. I popped it back in , there is a metal piece that was messed up. It came/ happened out of nowhere. I’ve never had an issue with it.
