“i was driving my car and at a stop sign i started accelerating when the light turned green - i must have been going 45 mPH after the light and all of a sudden my car went into hyper acceleration speeding up to 80 mph, i was pumping my brakes and the car was still raging to accelerate. I almost ran into a semi truck in front of me becuase i could not stop my car from accelerating, my foot was on the brake padel not the accelerator and it would slow down but as soon as I take the foot off of the brake - it would go into a rage accelration again, my car also gave WBA restricted warnings while accelerating.

However, the brake pedal instantly became extremely hard, felt completely locked up like a stone, and was impossible to press down. Despite having ample distance to stop and applying all my body weight and force onto the brake pedal, there was zero brake assistance from the vehicle, and the brakes failed to engage. The onboard Forward Collision Warning and Automatic Emergency Braking also failed to prevent the accident. As a result, I was completely unable to reduce the speed of the car, and my vehicle…”
