Re: American Honda dealers...
The more I think about it:
The only solution, equitable resolution, is for Honda to work with their customers, to realize we're beta testing their experiment, listen and act on our observations, reduce the onerous cost and miserly approach to replacement of dud batteries, and first and foremost: be candid.

Re: American Honda dealers...
Hi,
I'm a newbie here and have a 2004 HCH Manual that just turned over 85,000 miles. I bought the car in 2006 with 53,000 miles, from a local Honda Certified Used Car dealer. The car has seen mostly urban driving cycles the past 2 years, with the occasional bi-monthly highway trip. A/C does see seasonal use in May-Sept.
On a side note: I recently replaced the under-hood 12V battery (this was NOT really necessary, I just wanted the peace-of mind with winter fast approaching),
And as far as I know the IMA (144V) battery module has never been replaced. The car performs well and typically gets an indicated 38 - 42 mpg in city use and close to 50 mpg highway. (We do live at 5000 ft ASL, which reduces mileage and power.)
About a week ago the IMA and CHECK Engine lights came on. (P1600 and P1433). At the time they come on the SoC dropped from 75% to roughly half that. Throttle response becomes noticeably sluggish, but the REGen/ASSist meter still works. And the SoC gradually moves up and down. The most I have seen it come back to is about 67 % when the codes are thrown.
When I clear the codes, I observe the following: REGen/ASSist immediately at idle shows (GREEN) charge and the SoC rapidly comes up to 100% within a couple of minutes. When the car is driven, throttle response is crisp and instrumentation shows "like-new" REGen/ASSist and SoC behavior in urban driving.
Then, usually with a day or so (usually less than 20-miles) the same codes return (P1600/P1433).
To the best of knowledge, the ECM has NOT been re-flashed or "Upgraded" by Honda.
1) Is there a way to determine the ECM Version level?
2) If Honda flashes the ECM, will it potentially mask the P1433 code? Making them less likely to replace the IMA battery of DC-DC converter under warranty?
3) What is actually happening when the P1433 code is thrown? It seems to put the system into "LIMP" or "LAME" mode?
4) Does anyone have experience with Honda's Certified Used Car Warranty or Third-Party Warranties, with respect to IMA failures?
Any advice (or dare I say Insights?) would be greatly appreciated.

Masking this with software upgrades is a bad idea- your car was constructed far before these software updates were written, and they were written for the HCH 2 in my opinion, not your car. Replace the battery pack and move on. Keep the software you currently have as well and be vocal about it. If your car has its orginal battery at 7 years, another 7 on one battery is not a bad thing.
