2010 Ford Fusion cruise control problems

I was pulled into a parking spot in the parking lot of my gym, and the car was close to stopping, or stopped. The car accelerated, and I hit the building. When the crash was over, I looked down and my car's gear was in park. Either the car was already in park, and my foot was still on the brake, or my foot was on the break, and as the car accelerated forward, my hand hit the gear, putting it in park. I have pictures demonstrating skid marks (showing the brakes were engaged). The car is a hybrid model.

While doing 50 MPH on a highway, the car suddenly lost power. The motor was still running, but it was as if it was in idle. Depressing the accelerator did nothing. I pulled the car over to the shoulder and stopped. The idle was extremely rough. There was a 'wrench' indicator light. I turned the car off. As I restarted the car, it was very rough to start then after a few seconds, idle was normal. I drove without a problem for about 20 miles when the problem re-occurred in the exact same manner.
