I was stopped behind a car inside of a parking lot about 15 feet behind it and all of a sudden my engine rev up, accelerated unexpectedly, and the truck surged forward. I immediately put the brakes to the floorboard to try to stop the vehicle but it continued to lunge forward. I looked down for a split second and saw that my foot was completely on the break pedal to the floorboard. I that instant i tried to put it in neutral and I ended up putting it in park. Even though I try to stop, I ended up, hitting the car in front of me My truck is at the cerritos california ford dealership. I reported it to Ford customer service with the same information about how it happened as above There were no warning lamps Immediately after the accident happened within four hours, i drove my truck to the dealership after consulting with my insurance company and Ford customer service Ford customer service stated they wanted the truck at the dealership right away before any bodywork or repairs be completed from an outside collision center so they can inspect it
