On February 10, 2017 the car horn sounded for approximately 10 minutes, and this repeated twice before 2 am. The car was in the driveway, and no one was near it. The key was on the table. The action was spontaneous. It stopped only when I unlocked the car door. When I started the car later in the morning at least four safety warnings appeared including "brakes" on the instrument panel. This behavior was confirmed by the dealer darcars Honda in bowie maryland, where it was attributed to a fuse box which must be replaced. I am afraid to drive the car, even if it can be repaired, because of the car's safety warning.
