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.
