Our car was in the garage. I opened the trunk not using remote opener, but from outside. I was taking groceries out. I was leaning in and picking up bags when I noticed that trunk door was coming down. I tried to move quickly out of the way and hit my left side of my forehead. Above my eye. As a result I have a black and blue under my eye and a bump on my forehead and now several days of headaches. So, what is happening is that car trunk door when it was opening reached or hit the top of the garage. That caused it to start coming down immediately. There is no sensor to see if there is something in the way. Similar to garage door where there a sensor that something is in the way and it will stop. We have a small video of what happens. The upload on the next screen does not allow for videos.
