The truck has only 40K miles on it. I was checking under the hood when without notice the heed dropped hitting me in the head and pinning my hand under the hood thus trapping me there. A rescuer released the hood release lever so I could escape. I had a lump on my head and my hand was /wrist was bruised. I am on blood thinners so I consider myself lucky. The stanchions that hold the hood open suddenly failed and will not hold the hood open.
