Speed Control Cable problems of the 2014 Ford Fusion

I was exiting a freeway when I experienced my first problem. In the middle of traffic, my car shut off and I lost most functionality of the vehicle. The dashboard displayed an alert ¿transmission not in park�. I was driving normally and did not press any buttons or make any adjustments to the gears. He only thing that was functioning was the brakes and steering wheel, I had no control over the gas. The problem happened again the next day. I was speeding up to get on to the freeway when my car shut off again, displaying the same message. However, this time, because it was night, the lights powered off and it was difficult to see what was ahead of me. I turned on my hazards and was forced to pull over to the side, place the car in park and restart the ignition and continue on. I called about the issue as soon as the Ford dealership opened the next day. They told me to bring it right in. However, the problem happened again before I had a chance to bring it in. I was driving on the freeway when I was trying to pass an 18 wheeler. I successfully passed the truck, but after I did, the power shut off again and I was sandwiched between two 18 wheelers. The next day, I brought the vehicle into the dealership. They took it off my hands for about a week while they tested it for problems. I received a call and the representative said that they fixed a cable that appeared to be loose that might have led to the problem, and also gave the car a software update. I was pleased with the response. A week later I was driving back home when the car shut off again. I immediately drove the car to the dealership. I called the Ford care team and they said they would open a case for a buyback. On sept 23, I received a voicemail from the dealership saying that they could not fix the vehicle because when they tested it it was functioning as it should. They can and will not fix or replace the vehicle.
