yesterday my wife tells me the odyssey won't start and also won't shift out of park. She eventually jumps it and all is well for the day. This morning, same story. Its completely dead and doesn't want to shift out of park. We jump it again, and its working fine. I go to autozone and walmart and both places test the battery (which is less than two months old) and autozone also tests the alternator and can't find anything. Google searching pointss me toward some posts here about parasitic current leakage but when I check that I'm getting 0A and 0mA as well.

Not sure what else to do at this point, and the dealership is closed until the 1st because of the coronavirus

Check if you got the exact battery. I noticed when my battery went bad it passed the Autozone test as well. I couldn’t get the exact battery at Costco but had to grab it from the dealer. A battery specialist store may have the exact compatible model and they will be open as they are infrastructure.

Huh? Compatible battery?

You need 12v
2012? Is the battery original?
At 8 years that battery would be on borrowed time.

Go to Walmart and get a brand new 24F with the freshest date code.

Also props to your wife for being able to jump it herself.

Yes its a Everstart Maxx 24F, so should be the exact battery. The date code on my battery is 6/19.

I'm reading that it might be because of the A/C relay, though I'm having some trouble locating that relay...I somehow also popped the cover off of one of the relays

first thing i would check is the terminals, and make sure they are tightened down good.
jumping the vehicle might be just enough to get a loose terminal connected.
Since the battery is new, that is the last area of the vehicle that has been meddled with.

Also, there is a TSB for the shift lever not going out of park with the brake applied.
solenoid issue.

If the shift lever doesn't indicate the vehicle is in park, it will create a no start issue as well.
not sure if its related, not likely related to a voltage drain, but will cause an issue going out of park.

interesting issue, hope you find it quick.
