My 2017 Cadenza has had 2 sunroof 'problem's in 8 mo. I wrote Cadenza but they said no recalls, but still under warranty for another 15K mi. so dealer fixed it and works fine now, Anyone get extended warranty? Does it cover sunroof. How much? ThanksI have a 2018 Cadenza. My sunroof doesn't close properly. The glass closes but the inner lining won't close. Instead, the back of the sun roof raises up. I can't get the lining to close at all. Any ideas what's going on? Anyone else havee this issue?
