Engine Noise problems of the 2015 Nissan Rogue

I was driving south on military trail preparing to turn right at pipers glen. The light was green and there was a white car in the middle lane waiting to enter military. I slowed down to make my turn and suddenly my car accelerated. If I continued to turn there was no doubt I would have hit the waiting car. I proceeded straight, passed this car and drove onto a grassy area. My front wheel hit the curb which slowed my car but pushed me along the side of the white car causing damage to both cars. The fire trucks came and a police car. Since no one was hurt I was instructed to leave my car there to be towed . My son picked me up and I called the towing CO. About 1 hour later I was called and told the tow was on the way. When we arrived to where my car was I was surprised to see the front lights on. There was a motor noise and the hood was hot . Whenwe left the car there it was locked and the motor was not on. If this were not the case I would not have been able to lock this car having a keyless entry. I am concerned about ever driving this car with less than 10,000 miles. I called both Nissan and the repair company and reported what happened. They told me they would scan the car but sometimes nothing shows up. I use military trail almost every day and pipers glen leads to my home. I am happy that no one was hurt but haunted by realizing what may have happened if I attemped to make that right turn. Both these roads are city streets. I have no picturesexcept for my memory.
