I have a 2016 XC60 and over the past couple of weeks, I've experienced the drivers seat starting to move while driving the car. This has happened to both my wife and I on different occasions and we've definitely not had anything touching the controls on the side of the seat. Also, I don't know if this is connected, but the car seems to have also recently 'forgotten' the memory settings for my key, to the point that if I start the car and move my seat to correct position, then open the door, the seat (and mirror) settings will completely change. Has anyone else experienced this - if so, did you manage to find out the cause?
