A day or two after purchasing vehicle I was in a cramped parking lot and when I applied the brakes the vehicle suddenly accelerated. This happened twice, once going forward and once in reverse before I realized that my foot was partly on the brake pedal and partly on the accelerator. It has happened at least eight times since then. I have found that it happens more often when I am wearing wide soled work shoes. (GMC markets this vehicle as a work truck.) this is a very dangerous problem which caused me to nearly trap a woman who was standing behind her car in a gas station. Fortunately I was able to stop in time but she and I were both visibly shaken by the incident. I reported the condition to the dealer from whom I bought the vehicle but the response was that I should be more careful.
