sweaver123 described my experience last weekend with one exception. Sunroof stuck open, open and close rockers were unresponsive. The vent button allowed me to inch it closed with several stabs at the button and ended up stuck in the "vent" position. I let the car sit for 30 minutes or so and restarted. I hit the "open" button and the roof stopped at the 1/2 way point. Based on the post by 426 I was thinking a calibration issue. I held the vent button down for about 10s, released and then hit the close. Works fine now but I certainly will not be surprised to see this happen again. This was the warmest day my car has been exposed to since delivered (80 deg external). Possible factor/trigger?
