Some of reported water leaks through the roof rack rails when the hold down bolts are. I believe the body side uses a threaded rivnut insert which can loosen, or if the bolt itself is loose water can work its way in past the threadds. The rivnut can be snugged with a rivnut tool, or with a bolt, nut and washer.
