Mine did this too. Dealer replaced the gasket at the third brake light and the gasket for the whole back window. 6 months later (and after warranty expired) it began to leak again. The replacement of the gasket for the back window never did correct the whole window assembly from shifting and squeaking. Only leaked during extremely hard rain or in a car wash but a steady flow of water leaked in each time.
Water leaks that appear at the headliner and rear seat area have been known to be coming from the rear high mount stop light. The gasket that seals the light becomes warped over time and allows water to enter through the stop light into the cab area. A revised stop light is available, but I have found that properly placed caulk or foam tape will work also.
