Consumer Description

While adaptive cruise control was engaged on highway, it would disengage and harshly break even though there was nothing ahead as an obstacle. If there was a vehicle behind, it would have created a significant change of collision. During a 5+ hour drive, this occurred 20+ times. It seemed to occur when cresting small hills where visibility was somewhat limited ahead and when there were few cars ahead. In a few occurrences, there was a warning chime, but in other cases, it disengaged and braked silently. This just happened yesterday, so it has not been inspected by Tesla.
