I posted this thread a few days ago regarding some weird electrical issues:

https://www.carolinafirearmsforum.c...yssey-more-questions-electrical-issues.38544/

Back story: we got this 2010 van on Sunday, 1/13 at a local, well-known, well-respected dealership. I talked with the salesman, told him what was going on. I told him that I understood that the van wasn't under warranty any longer--caveat emptor and all--but this is a safety issue: lights not working, and doors not working.

He told us to drop it off, they would look at it and "run diagnostics," but wasn't making any promises. The last two days had awful text communications ("they are looking into it," etc.). Today he called, said both fuse boxes needed to be replaced, they are going to replace them, and will give me a loaner until the van is fixed and ready.

While this isn't the period on the story, it's a whole lot better mid-story than it could be. I am hopeful for a happy ending.
 
@llaht , @Mike Overlay , they are footing the bill. Didn't see anything with the carfax about it being a flood vehicle (we looked). After some research on my own there seems to be a common theme with these vans about moisture and the electrical system. I just wish I had known about it before we bought the van, we may have gone in a different direction.
 
A girl I worked with at the Dr.s office had a Odyssey, and had a lot of transmission troubles....
 
If it were me, and I couldn't duplicate the concern, I damn sure wouldn't be guessing on the expense of two very expensive fuse boxes.

As for a flood vehicle, more than likely if the water was deep enough to damage the underhood fuse box, damn near every computer in the car would be damaged. Constant and repeatable issues would be apparent

you are so smart....you should be a mechanic. Now go comment on my F350 thread while you are loafing on the internets. :)

The issues were only after the big-ass rain last week, and I found a Honda TSB about it (gave it to them). Not all of the electrical systems/components were bad, a handful, but enough that made it a safety issue. The day after it rained, all systems came back to life.

The TSB actually had a way to duplicate it: with someone looking at the fuse boxes, someone else sprays the outside of the van with a hose, and look for water entry. I don't know if they did/did not do that. But they do seem to be taking this seriously.

@Sneakymedic , there were some years with transmission issues; our year was not one of them. That problems I did see in my pre-purchase research.

right there...fix the water leak.
 
Could it be that the damage was so bad from previous leaks that is why they have to replace the fuse boxes? Believing they read the TSB and will seal the areas to prevent it from happening again.

If that is the case, why aren't you having issues currently?

But I was having issues; also, per some Odyssey forums, some people reported that a couple days after a rain most if not all systems (doors, lights, etc) would resume functioning.

I am not a mechanic so I am trying to make the mental leap between the symptoms, the cause, and the fix. Perhaps the symptoms were the same as the TSB but caused by something entirely different? I don't know. I don't know what they saw in diagnostics that necessitated a need for two new fuse boxes.
 
A fuse box is a constant. It either functions or it doesnt. Something causes it to not function. Nowadays fuse box are "smart logic", they have circuit boards in them. But they still perform the same functions, just differently.
 
Honda uses a smart fuse box called a MICU or multiplex. They can drop out randomly and on different circuits. Used to see problems with Civics and CRVs but can’t recall ever doing one on an Accord or Odyssey. Glad they are taking care of you
 
Any chance the windshield was replaced, see if the glass has Honda markings or other brand. Poor sealing will let water inside.
