It appears that all Honda Hybrids have the same IMA software when you buy a Honda Civic Hybrid. How do I know. Just about every year model has been mentioned in this forum. Every Honda is having this issue. If the sofware fix was the solution to this problem, then the new cars would have the fix and they would be running fine and not mentioned in the forum. But that's not the case. Every model year is having this problem. What does it tell us? Honda has not figured out a way to use less electricity for the IMA system. Therefore, the batterys will continue to degrade much much sooner than expected. My 2007 HCH began to degrade about 25,000 miles. However, listening to owners in this forum, it appears the newer HCH's degrade before they reach 10,000 miles. Now you know why HCH owners are in a pickle.
What can you do? If you take it down to the dealer they will say you need "the fix" first. A week later, after the light comes on again, they will say you need a new battery. After they do that they will pray they will never hear from you again because they have "fixed" the issue. If you bring your car down again they have to say "we can't find an issue" or "your car is running just fine" - that will be $168 please diagnosis- thank you.
I suggest that you put on your army boots, and get into the ring and put up a defense. If you need some suggestions as to how to start the process let me know. Whatever happens dont let them apply the fix to your car. You can fight HOA and win.

2007 Honda 49K mi.
I asked my Honda Dealer (the assistant Service Manager) if the fix could be "undone" and he said no. I called the Service Manager and said that HOA said I should get the low mileage "diagnosed". I said "so was I now expected to pay to find a problem that we know what it is?" He said I shouldn't have it "diagnosed". In other words, he knows what it is too. He was very rude and just told to me call 800 blah blah blah which I recognized as the HOA number.

Thanks Jdenver and everyone for some good insight. I will definitely need some advice as to getting in the ring with Honda if things persist.
So here's an update of my car. Once a week, the IMA and engine light will turn on...i tighten my gas tank cap and all is well two days later. I notice my battery is charging well, and my battery assist is doing great too. Haven't seen a decrease in mpg as well. Does this type of thing sound familiar? does this sound okay or is there something happening to the battery as time goes on and i'm not able to see it?
Thanks for everybody's advice! it's good to know that we're not alone in this.

My IMA light did not come on when I had a fuel cap problem. There was a "check fuel cap" message on the information readout. Don't know how yours is connected to tightening your gas cap.

My honda dealer said that if my gas tank cap is not tight, the ima and check engine light will turn on. Are they trying to mess with me?

This isn't uncommon in most cars, at least as to the Check Engine Light. I didn't tighten my cap enough in my 2000 Toyota Camry Solara and the light came on. However I would be surprised if the IMA light came on from that issue. As to the question about "is the software fix reversable"; of course. A flash upgrade is simple computer science. Flash memory is found on a lot of devices, like hard drives. When you "flash" the memory you are changing the software located on the hardware. The reason they can't reverse it is likely that Honda did not give them the software (code) to put it back. So they have nothing to use software wise except for the "upgrade" or "fix", which we pretty well can all agree is neither. The evidence is pretty strong that it is intended to delay final battery failure but that it is just delaying the inevitable at the expense to the owner, and to the betterment of Honda (temporarily). Until Honda modifies the batteries or simply sucks it up and gets used to the idea of changing out these batteries one or more times prior to the warranty expiration, they are likely to continue to have these problems. My opinion, yours may differ.

To me it appears that they will try and prolong it as much as possible and change out as few batteries as they can get away with until warranties run out. Only the right type of successful class action lawsuit would cause a different outcome.

I have the same problem. No IMA light, but like a diligent little Honda owner, I had the IMA reprogrammed per the letter from Honda. My 2008 HCH now gets 20% less gas mileage. The service dealer told me they could do nothing about it and to call Honda America, which I did. After discussing this with three reps, the answer I got was that they would NOT turn back the update. I am severely upset since the whole reason I bought this was for the mileage. Now I have lousy mileage (in the 30's) and far less power. Note that I never had a battery issue...the car ran great and was the best I have ever had in terms of mileage!
I want to "put on my army boots", but I could use some help on where to start. I think Honda is completely hosing us on this issue to save their own butts by not having to replace batteries that blow prior to the warranty period.
Any assistance would be appreciated!

My milage never came back until the battery was replaced. However, it is most difficult if not impossible to get Honda to replace the battery without the IMA light coming on. The problem is it is hard to get the light to come on unless the battery is severely deteriorated. It will eventually come on, but you need to try and make it come on before the warranty expires if possible.

If anyone starts a class action lawsuit, I want to join. Please contact me in that case.
