While in a parking lot moving at very slow rate speed the car suddenly accelerated on its own. I had just slowly turned within a parking lot in preparation to backing into a parking space. I had just removed my foot from the accelerator and the car was almost at a stop and I was about to brake and put the car into reverse when it suddenly and rapidly accelerated on its own. My foot was not touching the accelerator at the time (it was over, but not yet touching, the brake). The car felt as if someone had suddenly slammed on the accelerator, but my foot was not on the accelerator at the time. Luckily my foot was over the brake when the rapid unexpected acceleration occurred and also luckily there were no cars in front of me. I was able to immediately slam on the brake so that the car did not hit anything. Before I was able to brake, the car quickly lurched forward at a surprisingly rapid rate of speed for a short distance. Quick application of the brakes stopped the sudden and rapid forward movement of the car. I did not notice any warning lights or messages on the car. This could have been a very dangerous situation. If someone had been walking in front of the car, they would have been hit and potentially seriously injured. If there had been cars parked in front of the space I was about to back into, the car would have hit them and caused damage. This happened earlier today and I have not yet reported it to the dealer. No police or insurance personnel were involved as I managed to avoid an accident. The event occurred today, Wednesday December 3rd at about 11 am. There were no other witnesses. To my knowledge this is the first occurrence of this rapid unexpected acceleration for this car.

I experienced sudden acceleration in downtown and almost hit three cars, caused me to run three red lights and almost hit pedestrians. I had the car, 2017 outback Subaru towed to the dealer and was told there are no recalls, but saw many problems listed on the federal safety agency website. It was terrifying and still shakes me up when I think what could have happened. Subaru told me this was the first they have seen this and that I do not have the extended warranty and I would be held for the cost. I am beyond upset. They tried to have me pick up the car after finding nothing. I told them they are to keep it until they find the issue. I have a loaner from them.

1) the car accelerated without any change in my driving. My car is available for inspection. 2) My safety and the car in front of me were at risk since the car was accelerating and removing my foot from the gas didn't reduce the speed. 3&4) I haven't had the car inspected by anyone and it can't be reproduced. 5) There were no warning signs. My car is well maintained and I follow manufacture recommendations for maintenance. The first time it happened was in the morning on my way to work in Phoenix, AZ going the speed limit, when it accelerated and removing my foot from the gas didn't reduce the speed. My first thought was I was going to smash into the car in front of me at full speed. Luckily, my brakes did work and I didn't hit the car that was quickly approaching. The second time it happened, it was early morning in Chandler, AZ, I was going the speed limit and the car accelerated as I was taking the onramp for the freeway. Once again the only way to get the car out of the accelerated mode was to hit the brakes. It has not occurred again within the last 3 weeks.
