The vehicle has a sensor in the front that will auto brake if it thinks I will crash into something . However many times its braked theres been nothing in front of the car. Ill have great distance between my car and the one in front of me. There have been at least 4 incidents since Ive owned the car (1 year). Theres no active recalls, and the light will flash that Im going to hit something until I shut off the car. Once I turn it back on the warning collision light is gone.
