Mine leaks too. Bought my 2016 Rebel on 12/30/15. By 2/5/16 there was a significant leak coming from the screw cap on the driver side grab handle. Leaks onto the dash controls and driver door speaker and floor. Took it to the dealership on 2/5 and after 6 days of being under a water simulator, they claimed they could not find a leak and suggested that i may not have closed the sunroof all the way. Light rain last night and the leak is back. Took it back to the dealership today, 3/25, and was made aware that there has been some service bulletin put out for a faulty seal on the sunroof since the last service date. I won't accept that as the issue due to the fact that the dealership claims they were unable to get it to leak when i originally brought it in. Certainly feels like I'm being jacked around and it is more than frustrating. After searching several forums, I'be discovered that several people have had the same issue with their new dodge trucks and that is comforting, yet terribly disappointing at the same time.
