I was driving on a country road and shortly following acceleration after a left turn, the cars forward collision warning went off, but in an unusual way. It will generally beep and flash the brake signal a few times if the forward collision warning activates. This time I heard one loud beep, saw a flash of the brake signal, and then the car slammed on the brakes to a complete stop. Luckily, there was no one and no other cars around me as I was on a small road without much traffic. The car is currently at the dealership being evaluated. I have sent a request to the general manager to investigate this situation further than just a basic code run or recreation of the malfunction. I do not feel comfortable driving this car without a clear diagnoses and repair.
