FORWARD COLLISION AVOIDANCE: WARNINGS

My car has intermittently triggered false collision warnings—approximately 8 to 10 times over ~8,500 miles. Each time, while driving between 20–40 mph with no visible obstacles, the system issued an orange collision alert, sounded an alarm, and abruptly applied the brakes. This sudden braking poses a serious safety risk, as it could cause a rear-end collision. The vehicle has been at the dealer for 14 days and remains there, as they’ve been unable to replicate the issue or find any stored fault codes.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

I was driving at 40mph on a town road on a dry, sunny day when, without warning, the brakes slammed on extremely forcefully, almost to a full stop, and a big triangle showed on the dashboard with the words COLLISION WARNING. I don’t recall if there was an audible alarm or not. The warning disappeared and the car resumed forward motion almost as quickly as it had appeared. My body jolted forward against my seat belt and items on the passenger seat went flying forward and fell on the floor. There were no other cars on the road at the time but, if there had been anyone in back of me, it very well could have caused an accident. My neck and chest are quite sore the day after this happened. I stopped the car and walked around outside and did not see anything out of the ordinary - nothing in the road either. It was a paved secondary road without potholes in the immediate vicinity. The dealership will be picking up the car to inspect it and implement an “alert” upgrade service for the front camera system that may or may not have any connection to the problem.
