if you have the owners manual it will tell you how to get it out of park,,,, you have to shut the key off,,, pressing park brake and set it,,, turn the key on and start the car,,, and then release the park brake.. you have to do that every time you shut the car off and place it in park.. The reason it does that is because your brake lights are not working,,, could be the brake light switch,, or a broken wire..
Mine did it because of a broken wire when the police stripped it for auction
