Just wondering if anyone else has noticed a small vibration when using cruise control on highway. Was traveling with cruise set at 72 mph and noticed a small vibration in steering wheel and on floor boards when the dash Econ lights switched from green to white. It's not big deal but it is noticeable. It's confuses me because it's noticed when dash outer lights are white and goes away when they switch to green for Econ. That's sounds the exact opposite of what it should do with vcm activating. Any thoughts?
