I had a service tech drive the car and he claims it is fine. However he only drove it in the dealership lot and the pavement was seamless and smooth. I explained to him that the buzzing was consistent when I went over small bumps or changes in pavement. It was hard to pin point, not sure if it is just in the dash or the windshield vibrating. They ignored the issue claiming it couldn't be duplicated. I hear it every time I drive the car and any one that has ridden in the car has also heard the noise. My girlfriend has the same car; we bought them on the same day at the same dealership. She has no issues and I drover her car on the same roads and don't hear anything similar. Very disappointed in Honda!
