Didn’t see anything when I looked. It started again when I reached 30 mph. I looked backwards and saw my back right window was all the way down. It stopped when I put it up. Anyone else experience this? Is it a design flaw?
Most cars do this. One window open creates a resonance at low audio frequencies. Open a second window or close the open window.
Yes. My empirical observation is that a one-inch opening of a window on the opposite side of the cabin is enough to suppress the resonance.
