Has anyone had difficulties with the rear wash pipe where the detachable pipe on the hard top connects with the washer for the rear screen? Mine keeps coming off and spraying water inside the rear of the vehicle. The dealer has not been able to resolve this and says that they have not had anyone else with the same problem. This seems unusual as the system seems pretty inadequate. Any suggestions to resolve this would be welcome; but remembering that it is necessary to detach the pipe each time the hard top is taken off.
