Upon driving on the highway using adaptive cruise control and lane keep assist, the �collision mitigation: braking system problem. See your dealer� message popped up. Honda sensing functions were all disabled as well as regular cruise control. This happened on a cloudy evening as the sun was setting. No rain or inclement weather. Message went away only after parking the car, turning it off and restarting it.
