The car suddenly braked without warning, and the road was clear and no interference.
Trying to come to a redlight stop at about 35mph. Brakes stopped working and engine started revving really high by itself while trying to stop. Almost slammed into the car in front. Could not reproduce the problem and have no idea what is going on. The car also has all the safety features to prevent hitting something but did not work. Luckily the car in front moved forward to avoid the collision. Turned car off and back on to try to reset the car.
