Slowly pulled car into the driveway. Entered the garage with my foot on the brake. Half way into garage, the engine over accelerated and made the car lunge forward. My foot was still on the brake pedal. The brakes went into ABS mode, with pulsating. The car rammed into some storage totes and also my snowblower. The over acceleration of the engine stopped. All of this took about 10 - 15 seconds. No amount of pressure on the brake pedal stopped this car. No, I did not have my foot on the gas pedal. The car went into my local Chevy dealer 2 days later. I was told that they ran some tests, had it up on a lift & even had a mechanic take it out to try to duplicate the problem. Of course, they couldn't find anything wrong. Someone needs to do something about all these over & under acceleration problems before lives are lost! my car has a few minor dents on the hood, from falling totes my snowblower is slightly dented but my nerves are shot. I am really scared to drive this car.

My wife was driving 3 car lengths behind another vehicle. They stopped at a red light, so she applied the brakes. She said the brake pedal was stiff and did not move, also, did not stop vehicle. At the same time, the front wheels were pulsating and moving from left to right without her moving steering wheel. She pulled up emergency brake to stop before hitting car. What should we do?

I was pulled over by a police officer and issued a fix it ticket because according to the officer neither of my rear brake lights were working. I might add that the officer followed me for several blocks and saw me stop at least 4 times before pulling me over.

I was in the car with my son pulling into my yard which is at an incline and the car accelerated on its own. When I stepped on the brakes they failed and the car crashed into my brick house. The car has been totaled out and the house has structural damage. All the airbags deployed, however, my son had no injuries and I walked away with significant bruising and lacerations on my legs. I have contacted GM and they are currently investigating my claim.

My husband was pulling the Chevy Spark into a parking place when four people decided to cross over it. When the brake was applied to allow them to safely pass, the car accelerated instead. The brakes pressed back against his foot he said and car eventually stopped. We were both confused, surprised and afraid! the car was not driven again until I took it out two days later. It happened once more when I was braking at a red light behind a large truck at a very low speed. I pressed the brake harder a second time and then took my foot off the brake. This time the acceleration continued even after my foot was taken off the brake. I shoved the car into park to get it to stop. I sustained a broken toe and fractured ankle from the force of trying to stop the car. A few months before this, when applying the gas, the car would not accelerate at two consecutive red lights. Engine was very slow and car was not able to accelerate to the speed limit and hesitated all the way home. The car has a factory recall on the air conditioner right now as well, which we received from GM. We are terrified to drive this car not knowing if these defects will continue! the car is in the service department and we are in contact with the dealership about a buy back from GM. We bought the Spark August 30, 2013, so it is not even a year old. I have done a search for others who may be having the same or similar issues. There are reports of very similar incidents on sites for complaints for both issues of brake acceleration and the gas pedal hesitation also reports of the Spark engine stopping in traffic. This is very concerning and dangerous. We hope this is taken seriously and investigated.
