On January 7, 2014, my 2013 C-Max Energi self-accelerated. I was stopped in the left-turn lane, then gently pressed the accelerator (as I had hundreds of times over the 13K miles I've driven the vehicle.) It took off with substantially greater acceleration than I intended. I took my foot off the accelerator, but the C-Max kept accelerating. I applied the brakes - car still kept accelerating. I put the transmission into neutral and brought the car to a stop. Upon returning to drive, the car again accelerated: this time, I never put my foot on the accelerator. Stunned, I watched it accelerate to 30 MPH before again returning to neutral. I put the car in neutral and coasted into a safe parking lot, then turned the car off. When I re-started it 2 minutes later, the self-acceleration problem disappeared. I found one similar report on the internet, but I have not found a TSB from Ford acknowleding this problem.
