While loading my vehicle during a trip, when I turned around to pick up a bag and turned back to put it in the back of the vehicle, the entire liftgate had lowered halfway and I hit my head forcefully on it from a crouched position. I have a pretty serious concussion from this. I was not aware that this malfunction existed in this vehicle. It is very dangerous and almost knocked me out! This happened on a Saturday and I cannot afford to go to the ER, so I will go to my Dr. on Monday (tomorrow) morning. (unless my roommate sees my condition worsening) I am resting but my head hurts and I am very nauseated and tired. Blurry vision.
