Travelling at approximately 47 mph, with nothing in front of me, the car's emergency braking system engaged completely unexpectedly, slamming my car to a stop. This caused a pick-up truck, to hit me from behind. The emergency brake light appeared at the exact same time as the car's emergency brakes applied. The driver of the other car confirmed there was nothing in front of me. The Honda dealer where I brought the car the next day stated there was nothing wrong with the camera or radar system. This failure caused an accident, and could have been much worse.

If you are having this problem where every warning indicator is illuminated, codes scanned but no clear solutions to the "Christmas Tree dash board This is an ongoing issue with the 10th generation and there is no definitive "fix" recognized by Honda. Sometimes it is the battery, the alternator, the head gasket, the ECM, injectors....the list goes on and on. Sometimes the repair fixes the issue, but based on research, the issue typically comes back shortly after the service department throws another part at the problem.
