Complete electrical failure of all components of the vehicle when the power switch was turned off after parking. Emergency flashers, brake lights, headlight and horn also would not work. I discovered the positive electric cable bracket, on the battery, was broken and held together only by the red plastic cover. The bracket is very thin compared to other vehicle battery cable connections on other cars. It appears that the bracket (with red cover on it) was bumped during vehicle assembly cracking the bracket. The red cover hid the damaged bracket until it broke completely today. If the vehicle ds start, it will run normally. When the positive cable loses connection, the vehicle continues to operate normally until it is shut off. Then all systems shut down immediately. Recommend Honda redesign the cable bracket to make it less prone to breakage.
