The rear trunk lid struts fail to keep the trunk open causing the trunk to close without warning and has hit me in the head several times while unloading groceries. It is also very hard to open as the trunk is quite heavy. This was noted to the dealer during the warranty period but they said they were unable to duplicate it. The struts need replaced. I feel this should be a recall since it has occurred since the vehicle was new. Someone could be severely hurt or become trapped in the trunk. The struts are under designed for the weight of the trunk.
