2005 GMC Envoy. Coming to a stop, put foot on brake pedal, foot slipped off, car continued moving into passing car. This also happened July, 2009 but with more damage. Prior to these incidents, had several times when feet slipped. [2 different drivers] pedal is either wrong size, material, or placed in wrong place. Afraid to drive it now, it is parked in garage. Your form does not allow for "brake pedal". I marked service brakes, but it wasn't the brakes.

In August 2005 on a trip, exiting off ramp brake pedal went all the way to the floor, was able to "pump" it and get response. After shutting vehicle off, setting & restart brake pedal again goes all the way to floor. Upon return to dealership master cylinder was replaced. A few months later brake pedal becomes extremely "spongy" with no stopping power. Dealership bled brakes and said problem was air in system. Still no improvement, extremely soft pedal and unit will not panic stop. Took back to dealership end of June 2006 and they replaced master cylinder a second time. Unit is still no better and in my opinion unsafe to drive if it will not panic stop. Dealership says GM has told them to order more parts, but do not know what the problem is.

On the night of Saturday (at 9 P.M.), December 10, 2005, I drove my GMC Envoy slt to michael's. when driving through the parking lot, my daughter and I heard a loud grinding noise from the underside of the vehicle. We parked the car, turned off the engine, then turned the vehicle on again. Several icons that had never been displayed on the dashboard screen appeared, and my vehicle's clock reflected 12:00. The clock was set for the correct time initially, and never tampered. We shopped for 20 minutes and returned to the vehicle, started it up and again several icons appeared. The clock said 12:00 though it was 9:30 P.M. we drove through our neighborhood viewing some christmas lights for about 10 minutes. As I pulled onto our driveway and began breaking to stop the vehicle and and park it outside of our garage, it did not respond to breaking. When I pushed the brake pedal down harder, the vehicle continued at the same speed. I screamed that we were going to hit the garage door, and at that moment felt the vehicle accelerate although I had the brake pedal pushed down all the way. It slammed through the garage door, I quickly shifted into park and shut off the engine. My front and my daughter's front passenger door could not be opened and we smelled gas. My husband called 911 and emergency vehicles responded. They determined it should be safe but asked the furnace be turned down so that it would not cause any combustion and to keep the area ventilated.. the garage door was totally demolished, and drywall damages in several spots. A technician from overhead garage doors removed the remnants of the door. My daughter's car had minor paint and dent damage as it was in the garage already. GM's roadside towing hauled the Envoy onto a flatbed to take to the dealership. We explained the accident to GM when we contacted them for roadside assistance. The vehicle is now at our dealership, andy mohr, noblesville, in.
