On two separate occasions, while unattended and sitting in my garage, the vehicle seemed to be attempting to start by itself. Instrument panel warning lights were all flashing on and off with ignition clicking. The key fob was nowhere near the vehicle. I started the vehicle but then WAS UNABE TO SHUT THE ENGINE OFF by pressing the ignition button. ALSO FEARED THE POSSIBILITY OF AN ELECTRICAL FIRE. Had to pull the fuel pump fuse to do so. A local Honda dealership diagnosed (by reviewing Honda’s service library) as a faulty ignition control unit and replaced at a cost of $1,100.00.
