I had this problem too, in my 2010 honda minivan. I just googled "parasitic battery draw honda odyssey van", and what do you know... Lots of people had the same problem.

For me, it was just a relay to the air conditioner compressor that was stuck on. Quick fix was to pull that fuse, long-term fix was to buy a new relay (which cost $10).

You can probably solve your problem easily by hooking up a voltmeter to check the draw, and then methodically pulling fuses. If you find out what fuse stops the draw, you might be able to figure out what needs to be fixed (manual should tell you what each fuse is for). If it's something you don't need, you can just leave the fuse unplugged!

I'd check the AC fuse first.
