Electrical System

When shifting my car into park the vehicle did not recognize that the gear was indeed in park. I would get a message saying “Shift to Park” and I could not fully turn my car off. This problem made me feel unsafe as I didn’t know what to do when it wouldn’t turn off. My battery could have run down and I would be stranded. In researching this problem GM was sued for the very same problem in earlier models so I am incredulous that they have not fixed this issue or initiated a product recall. I had to have an internal switch replaced at a GM dealer service center at my expense and the car only had 15263 miles on it.
