12 volt positive connection for battery get corrosion. The connection was covered by plastic cover so I could not see any damage until my car didn't start. I was lucky because it was happened at my garage. However, I am very scared by this problem. Because, I do not have any protection without battery if the terminal is disconnected on the highway. This problem is the same or more dangerous as gm's ignition key recall. Please research how many Honda vehicles have the same problem, and how many people got injury or fatality as quick as possible.
