Automatic opening rear hatch opens without a command to do so. Several times I've found it open when parked in public parking lots. Twice it has opened within my garage, causing the hatch to strike the garage door and scratch and damage the trucks paint. On one occasion the vehicle was parked outside and backed up to a fence. The hatch opened and struck two shovels that were leaning against the fence. In turn, the shovels fell along the side of the vehicle and caused $800 in paint damage. The reason this happens is because the shape of the remote key fob is convex instead of concave. In turn, when the fob is in your front pants pocket and you knell to pick something up, pressure from you leg cause the the hatch switch to engage and the hatch to open. I know this because it happened one time when I was nearby the car when the hatch inadvertently opened. The problem is excessive because the fob has a long range. Consequently, the hatch can open when you are well away from the vehicle (e.g. inside a building). I've complained on several occasions to my Mercedes-Benz dealer and have been repeatedly told that this has never happened to anyone else. I find that very hard to believe.
