I have learned that the VCM on some Hondas can apparently cause a noise/vibration that sort of sounds and feels like drivng over rumble strips but is a much more muted sound/vibration. My Touring started this after about 2500 miles. More so while mountain driving than freeway. I am home after a vacation and am going to nearby mountains to see if I can replicate the noise/ vibration. Will be interesting to see if it does not show up in Sport mode.
