2014 Kia Sportage EX AWD
I get this rattling sound that is coming from the front passenger door on my 2014 Kia Sportage. It happens whenever I am going at fast speeds(highway) and/or bumpy roads. It also only happens when the window is fully up. If I lower the window even the tiniest bit, it doesn't make the sound anymore. One thing that I noticed is that when you close the window fully up, the upper part of the door frame around the window bends slightly outward due to the force of the window acting upward on it. I assume this is normal and happens on most modern cars as the force of the window keeps water out. Because I am only hearing the rattling noise when the window is fully up, it is probably altering the seal(increasing the gap due to the bending) at the top of the door. I am thinking of bringing it in to the dealership to see if they can fix it. Any ideas from anyone about this problem?
