2008 Dodge Grand Caravan SE 4dr Ext Minivan (3.3L 6cyl 4A)
Let me start by saying, I like the van and this is my second one. But the new design has a whistling sound when doing 65-70 MPH. The problem is around the windshield on the unit, Between the window and the pillar that extends to the roof. The rubber insert is not long enough and it causes a whistle sound. You will need to tape the outside until you can run a thin bead of caulk under the rubber to prevent the wind from getting in. I do a lot of driving in a year (42,000 annually) and I currently have it taped and it has stopped the noise. Good luck.
