Unless something has changed, the default for the stop/start is on. When you press the button, you are turning it off. Start the car and don’t touch the button. Unless you want to turn it off.

Nothing seems wrong.. it maybe cause it's only 8 degree outside and you have your temperature on HI setting. Wait until the weather get's warmer to see if the problem remains to exist.
