Car battery died after leaving door open for less than 5 minutes, had to get it towed to the dealership only to be told it had a 100% battery life and they can't find the issue. Again car died and was taken into Honda to be told the same thing again. Car is always dying and its progressively worse.

On two different occasions a month or more apart, I got in to start the car and the battery was totally dead. No lights were on and no reason for it to fail. The second time, I took it to the dealer and they searched for hours (or so they claimed) and said there was no leakage current whatsoever. And the charger was working properly.

Anyway it hasn't happened since, but I still don't trust it.
