Ghia X completes itself

As I heard, there should be a broadcast today on a German TV station about self final cars. I also have this problem with my Ghia X. An example: I get off to refuel and take the key with me. I came back from the cash register, put the fuel note in the driver’s seat and clean the windows. Suddenly the central locking closes all doors. If I had also put the key on the seat, I would have looked stupidly out of the laundry. But I’ve known him for over a year, I’ve become careful with it. Has anyone else had such experiences?
