Got a call from the wife this afternoon.....battery dead. All the doors appeared closed. After hooking up the charger and trying to allay my wife's concerns about our 'unreliable' brand new Odyssey I researched the owner's manual and the Helm's Honda service manual. On page 128 of the owner's manual, column three, it states "with any door or the tailgate left open, the lights stay on about three minutes, then go out". At the top of column three is the header "On EX and EX-L models".....ours is a LX (Canadian). Sure enough when I 'closed' the tailgate gently, and it appeared closed from outward appearances, the interior lights were on (door activated position on the light control switch). With the tinted windows, day time conditions, and my height (6'2") it was not obvious at all that the lights were on. They stayed on for 30 minutes plus before I gave up. No auto off on the LX it seems. Lesson learned about shutting the tailgate completely and checking the lights just to be sure next time. And yes I was the one who last 'closed' the tailgate on her Odyssey.
