| Description of the problem | Initially in cold weather only, the tail gate / hatch / rear door would start to close slowly of its own accord. The electrical system would then assume you had attempted to close the door by hand and the electric motor would kick in and close the door on top of you if you did not realize and move. The force of the closing door is quite high to a degree that it was a struggle to stop it crushing a person. A child would not be able to stop it closing. The problem has continued to get worse and the weather has little effect anymore, the door will not stay open even on mild days. |
