Collision warning failed. Automatic emergency braking failed. Unknown if brakes were delayed or had issue stopping. I rear ended the car the in front of me, going from a stop while attempting to make a right hand turn. There were no system warnings or emergency braking applied although the car is equipped with those and many more safety features. During the accident the air bags were not deployed. So the impact was not severe but caused a combined $10,000 plus in cosmetic damage to both vehicles.
