Accelerator Stuck problems of the 2010 Chevrolet Traverse

The contact owns a 2010 Chevrolet Traverse. The contact stated that while driving 50 mph and attempting to pass another vehicle, the accelerator pedal became stuck in open throttle position. The contact pumped the brakes repeatedly and had to reach down to manually release the pedal with her hands. The vehicle was taken to the dealer for inspection but they were unable to determine the cause of the failure. The vehicle was not repaired however, the failure was recurring. The manufacturer was notified of the failure. The failure mileage was 56,000.

When attempting to pass (at a normal speed & situation) accelerator sticks & continues speeding up until I slammed on brakes(which didn't stop me) & pulled the accelerator up at the same time, this has now occurred 5 times over the last 7 months, it is terrifying when it happens, I have 3 kids in the vehicle with me most of the time, then today when it happened right after it started working properly I lost power steering when I apply my brakes!! not impressed with this vehicle right now!.

Vehicle suddenly accelatered and gas pedal stuck at about 65 miles per hour. I immediately took my foot off the accelerator and begin trying to brake the vehicle. At the first available opportunity, I pulled to the side of the expressway. While keeping both feet on the brake, I placed the transmission into park. The vehicle continued to rev rpms at the equalivent of about 65 miles per hour. I used my right hand to pull the accelerator up and the engine returned to a normal idle. I noticed no evidence of the floor mat being on the accelerator or in a position to cause the sudden acceleration or the continued engine rapid rpms. The same day, the accelerator stuck a second time and required me to pull the gas pedal up in order to get the engine to return to normal rpms.
