I had a similar reaction when I was shopping for my Genesis. The thread was about 30 pages long when I started to get serious about the car, around August of 2015. I spent a lot of time reading the thread. There were probably more people discussing the issue, or offering advice vs. users who were reporting an issue. I am now about 18 months in to a 36 month lease. No sunroof issue. While the issue is frustrating for those who have a problem, I'd bet that the majority of owners don't have a problem.have you seen the thread re sunroof rattles. I was going to get one with sunroof and backed off after a 60 page thread.
