it is a SUV, it has wind noise, every minivan, suv or SAV have more wind noise as compared to cars, so that is common is in this segment, the issue or complain should be the noise due to seals or side mirror, since SUVs and minivan have larger side mirrors they some time create whistling noise also, this could be due to many reasons, if it is a design issue it will be in every car and should be caught during testing. If we chose to buy SUV or any vehicles with higher roofline we have to deal with wind noise, with aero dynamic design it is minimised but styling prevents to go too much round edges.
