If you shift in neutral and open the driver's door, it will automatically shift into park unless you hit Neutral twice. As per the manual
AUTOMATIC RETURN TO PARK
Note: This feature will not operate when your vehicle is in Stay in Neutral mode or neutral tow.
Your vehicle has a safety feature that will automatically shift your vehicle into park (P) when any of the following conditions occur:
You turn the ignition off
You open the driver's door with your safety belt unlatched
Your safety belt is unlatched while the driver's door is open
If you turn the ignition off while your vehicle is moving, your vehicle will first shift into neutral (N) until it slows down enough to shift into park (P) automatically.
Note: If you have waited an extended period of time, (2-15 minutes) before starting your vehicle, unlatching your safety belt will cause this feature to activate, even with the driver's door closed.
Note: This feature may not work properly if the door ajar switch is malfunctioning. If your door ajar indicator does not illuminate when you open the driver’s door or the indicator illuminates with the driver’s door closed, see your authorized dealer.
