The road I was driving on is 55 mph on bear in. As I began to break nothing happened. A 90 corner was in front of me. 55th ave. I pushed as hard as I could on the breaks. It was smooth.. traction control was on. No breaking unit went into affect. It was smooth all the way into a tree head on. Zero skid marks! I was conscious the entire time closed on eyes right before impact. Air bags did work. The engine started on fire 3X. They had to use the jaws of life to remove the vehicle from the tree. I pushed so hard on the break that it broke my ankle, split my knee open and sprained my knee. I was taken to the hospital. Mileage on the vehicle was about 56K. This should have killed me. The breaks had worked fine before this.. no squealing, shaking etc. In good working order. Conditions were dark, dry roads, no wind. I do have reports but can not scan them. I loaded 5 images! please look into this matter immediately. Lives are at stake.

Brake pedal feels too soft and causes the car to have problems with making smooth stops. I noticed this change in October 2016. This problem is particularly dangerous when you are required to make sudden stops at intersections or in heavy traffic. This happens when driving on city streets, neighborhood streets and on highways. I am concerned that this could result in another vehicle from striking mine in the rear or a child being hurt or killed when I drive through my neighborhood streets. It is very unpredictable. I took it to my Chevrolet dealer and they said they were unable to duplicate the problem at that time. I am including an image of the dealer's service report from 11/09/2016. The problem still continues to this date, 8/8/17. Since the problem is ongoing, I cannot report an actual date, mileage, or driving speed.

First noticed this happening about 1 month after the purchase of this car. When stopped at a stop sign or red light, with my foot on the brake the car feels like it wants to lunge forward or take off. Or, when going from my foot on the brake to the gas the car wants to lunge forward once I press on the gas just a little bit.

Has happened off & on since I bought car October 2014. While at a complete stop car will rock back and forth as if the brake pedal isn't pushed down all the way & the car isn't sure if it is to be driving forward slightly or stopped. Even with me pushing the brake pedal all the way down to floor, car still rocks back & forth. If at stop light while doing this issue & light turns green for me to drive ahead car will not move till done having its rocking back & forth fit. It only lasts 15-20 seconds but can not drive forward while car is having fit. Is this the computer/stabilititrack not communicating properly?
