My vehicle has acc (adaptive cruise control) and, when set, will accelerate and brake as needed to keep a certain distance from the vehicle in front that the system has identified via the radar and camera. I had an instance where there was a momentary loss of positive control of the vehicle under certain conditions. In this event, it was a hazy afternoon with wet roads. I was following a vehicle on a road with the acc set. The vehicle in front started a deceleration less than 10mph/S and my vehicle automatically started progressively increasing braking action to maintain separation. 1.5 - 2 seconds following; it appeared as though the ABS kicked in and disconnected/overrode the acc witch subsequently stopped the braking action all together. As a result my vehicle proceeded torward the vehicle in front of me in a critical moment that required, now, even more braking action in conditions that initially caused the ABS system to activate under normal braking action controlled by the acc. I was aware and had not let the semi autonomous features of my vehicle lull me into complacency. I reacted quickly and a collision had not occered. Others may not be so quick to respond in a similar situation. I believe the system deactivated as a result of the ABS shaking the brake pedal or control linkages, where, in normal operation depressing the brake disconnects the acc if the system starts an unwanted acceleration or the operator simply wanted to disconnect the system without toggling the steering wheel disconnect switch. This feature is available on all limited ultimate 2017 Hyundai Elantras.

While driving, my car started to make a beeping sound I had not heard before. I looked at the dashboard and the multi-media system and I did not see any warning indicators/lights. When I stopped at a red light I put the car in park, turned the car off and turned the car back on (push to start). I proceeded to drive again and the car began to beep that unfamiliar sound again. Still no visible warning indicators/lights. I pulled over, put the parking break on, put the car in park, turned the car off and then turned the car back on. I began to drive again and the car was no longer beeping. While driving I stepped on the break pedal with the intent to slow down because of slowing traffic, my car did not slow down. I slammed on the break, the car still did not slow down and I hit the car in front of me. After I hit the car in front of me my car was still pushing, I stepped on the break again and the car felt as if it was still trying to push forward, I pulled the emergency break and the car stopped. A police officer was already on the scene, then notified us park police to come and take a report.
