My wife and I drove the new Palisade from Alabama to New Mexico and back earlier this month. We encountered numerous periods of what I think involves wind noise; however, there seemed to be two types of noise. One is the usual wind noise that one should expect when driving at higher speeds. The other was a noise best described as a humming sound that kicked in at 70 and above. The humming sound would go and come and seemed to involve wind speed and wind direction. Also, I noticed that the humming sound would go away when a vehicle passed us on the left side. When the vehicle had moved on, the humming sound returned. It seemed to me that the vehicle in the passing lane affected the wind flow in such a way that the humming noise was blocked temporarily.
I suspect that both noise sounds are related to defective door gaskets on the driver side. We never noted any high levels of wind noise on the passenger side.
