I just retrieved the beast from the dealer. They assured me that this was what they found. They traced the DC current draw to a minimally open deck lid and once corrected the draw was eliminated. Oddly there is no trunk deck lid "open" indicator warning light in the cockpit. They had replaced the battery once already so I know the problem cannot be sourced there. I'll just have to wait and see what transpires. I'll pay particular attention to the deck lid to be certain it is secured. Que sera sera.
