When the ECO button is on and I bring the car to a stop, whether at a light or stop sign, the car shuts off but not without giving a vibration. I had never driven a car with this feature so what I thought was normal for the ECO feature turns out it is very annoying everytime it is on, which comes on automatically when the car is started. I am currently driving a loaner from the dealership, the same model and when I come to a stop the car shuts down, but you do not feel the vibration. One cannot even tell that it has shut down and restarted. It feels nothing like mine, but the dealership is saying that it is normal.

I am sure there are others out there that are experience the same problem.
