Thanks for all the responses. Yes, it did close itself often but all has been explained. I was holding the lock button down for longer than needed, to activate the folding mirrors, which also may have contributed?? Thanks to two replies I now have a permanently open blind to let the light in and just use the closed position in very bright sunshine. Another pan roof related thread warned about leaks and water ingress. My only other related experience was with my previous car, a Toyota RAV4, which I recently changed for the Yeti. It was my only Japanese car to date, was very well built, and at 12 years old when changed had never leaked through the sunroof. I will be delighted if the Yeti can match that :-)
