This car had not been driven or started in 36 hours. it was sitting at the end of my driveway . there were no vehicles near it or close to any traffic. i noticed a black smoke coming from rear seat/trunk area of drivers side. This is where the batteries were located..I called fire dept. It suddenly burst into flames. The car burned up. The fire was so hot the doors blew open. Glass exploded and shattered. Tires Burned. This car was just sitting there! I would drive this car short distances a few times a week. I didnt see any light indicators on dash that alerted me to any problems.I notified Honda but they were not interested in inspecting it.
