Probably not related, but this sticks in my head.
Many, many years ago, vacationing on your island, we had to call the rental car company the second morning there to come start our almost new Nissan Sentra.
They knew what it was as soon as we called and said it happens there 'all the time'.
Turned out to be condensation inside the distributor cap (I told you it was many, many years ago).
I'd grown up in east coast winters and in humid summers, but something about the combination of climate factors there seems to somehow make condensation in auto electrics more an issue than in most places.
I just chalked it up to part of the daily hell of living on Maui.
