This has been happening about every other day for the past week or two now. I NEVER use my sunroof so im confused. I never notice it happening I just come outside in the morning or walk to my car in the lot and see it down. Is there a simple fix for this? It's starting to rain and I'm concerned I'll walk out to my car one day and I'll be flooded in. Oh well I guess I'm going to have to make a trip to the dealer :/
