Mar 2024 VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE Vehicle was driving on a slow traffic local street at roughly 10MPH. Spacing between car in front of me was around 30 ft. I was gliding towards front and ready to brake. Suddenly the vehicle start to accelerate hard by itself without driver’s operation. I tried to engage brake / gas pedal and was not helping. Front collision system did not activate like it suppose to. I ended up turn sharp right towards road curb and hit pole at average speed of 30mph or less. No air bag deployed. I then switch to Park. No warning lights pop up. All safety features on vehicles were turned on before the incident. Whats weird is the car is functioning normal now after incident.
