The sunroof would open halfway then get stuck. Closing was even of a hassle....making a loud noise and sounding like it was going to die. We just kept it closed. One day driving on freeway and at first it sounded like one of my kids started rolling down window so before i can even tell them to stop, the whole sunroof went flying off. Thank God noone was behind me or got hurt. Going thru insurance now just to get a window back in...Cadillac has to really look into this problem.
