Anyone experience a wind sound coming from their drivers side back passenger door/window? This occurs on the freeway at approx 60mph or faster. It sounds as if the window is not rolled up all the way. It has been to the Kia service department 2 times with no resolve. The service department has driven my car over 100 miles and they hear it, but have now deemed it “characteristic of the car”. We have the EX V6 model.
