My 2011 Chevrolet Silverado 1500 has unwanted acceleration. Its been happening for apprx a month, on and off. On Tuesday 10/4/2011 I was leaving my parking space at work, I had my foot on the brake as I was turning out of the space, the vehicle just took off - accelerating without touching the gas. I then hit the brake which stopped the vehicle. I then got on the highway - (I-94) to head home, while driving on I-94 my vehicle lunged forward nearly striking the vehicle in front of me. I then backed off and kept a safe distance in the event that it happened again, sure enough - my vehicle started accelerating on its own. I realized it was doing it and had enough distance between me and the other vehicles ahead, so I allowed the vehicle to take off. My silverado got up to about 1500 rpms at 60mph, I clearly had my foot off the brake and the gas, feet flat on the floor. I allowed it to accerlerate on its own for apprx 1 minute but then had to stop. It is clearly driving itself. I drove the truck straight to the dealership and left it for the shop to look at the next day. The service dept could not re-create the proble, go figure. In the past month I've nearly hit several parked cars when pulling into parking spaces as the vehicle takes off accelerating, in these events I was also able to stop the vehicle w the brake.
