After almost 12,ooo miles, I'm starting to experience some kind of buzzing resonance that come through to the dash, console, and can feel it in the gas pedal. It's weird because it will happen when accelerating and decelerating too, but not it's not a constant occurrence. Has anyone else experienced this? I wondering if the motor mounts are loose? The ICE runs great and the transmission seems to be operating as smoothly as ever. It's just odd that this started just recently.
