I was driving in heavy traffic (stop and go); i was fully stopped with my foot on the brake - i eased off the brake to slowly roll forward - absolutely did not place my foot on or anywhere near the gas pedal - as i eased off brake, i felt a strong "surge" from the front of the car- the car accelerated and i slammed in to a truck that was directly in front of me- i looked at the dashboard as this was happening and the "check engine" light and the "traction" light were both on - i tried to brake but the brake pedal was hard - i was stopped due to the impact of hitting the truck-- i am attaching the edr report as retrieved by a company lexus contracts with
