Thanks to all of you who have posted information on the IMA battery problems. I started experiencing similar issues with my 2009 Civic Hybrid about a month ago and the Honda Dealership Mechanic was useless...took the car in twice and the second time they said "Oh well, you'll probably need to keep driving it. Sometimes things have to get worse to get better". I did some research online, found your postings and used the information to talk with Honda of America about my experience and I just got a call from the Honda Dealership that they'll be replacing my battery...no questions asked, completely covered by my warranty as I only have 22,676 miles on the car. I'm looking forward to having my car back to running order but thinking about ditching it for a Toyota. The latest edition of consumer reports gives its lowest rating to the 2009 Civic Hybrid's electrical system and I'm thinking I'll probably have to sell the car for way less than I would normally expect for resale on a Honda. Oh well...

I'm wondering if there were mistakes made in implementing the software update. Maybe you could get them to do a re-install or at least verify the update is working correctly. Software controls the CVT ratios. I had the update and a new battery installed on my 2006. It performs as well as ever. My rpm is about 2000 70mph on a flat road. I have noticed that I get my best mileage by keeping the engine speed below 2000 rpm as much as possible.

bossless, I think the key to the good performance you get is the "new battery". That's the only thing that will return our cars to good, "hybrid"-like, working order. How did you get a new battery? Who did you send a letter to? (
Sorry if it's already posted somewhere above this huge thread)

I have put one transmission in that was covered by warranty and now after another 100000 miles I need another one. Plus all My engine mounts are bad. Makes the little 1400 rock and roll

I think I'll try bringing the car to the other Honda dealer in town and have them try to apply the update. The one I'm currently going do tried re-loading it with no change, perhaps the copy of the firmware that they are using is bad. Worth a try, I'll see how it goes.
#1224 of 1535 2005 hch IMA batteries
Nov 22, 2011 (1:24 pm)
Bought the 2005 new in Oct '04. On a trip in '05 and was rearended in OKC stopped at a stop light. While car was drivable, it needed to have extensive rearend repair. Once back home, after completing our trip, the car sat in the driveway for three days before it could be accepted into the Honda body shop. During that time, the IMA battery failed. Honda replaced it, but could not determine what caused the failure. It is now Nov '11, and on the 1st I had a check engine lite come on; took it into the dealer, and they said it was a sofware update that needed to be implemented. Did that, and now, Nov 22 the check engine lite, as well as the IMA battery lite or on, and the Honda dealer says we need ANOTHER new battery. Car has 72k+ on it, and is now on the 3d IMA battery. It never gave us the MPG that was adv't, but at 37 city 41 hwy I wasn't going to complain real loud - it was better than anything else I've had in a while. I've owned Honda's since the '67 model, and tend to replace them about every 6-8 years, and this is the first one I've had that has had to go back for a single item! Also own an '11 Insight which is working just fine!
#1225 of 1535 2004 Hybrid and bad software update causes IMA failure.
Nov 28, 2011 (4:38 pm)
OK, here is some information about getting a software upgrade on your 2004 civic hybrid. We got the O2 sensor update then 3 days later the IMA and CEL light came on. I checked the codes (1600 1433) and reset it. Every thing was fine again (no recalls, etc). Then 2 weeks later the complete IMA system went off line with the IMA and CEL lights on with the only code of 1600.
Went to the dealer and found out the O2sensor update was a 2 phase update with only the first part applied. The dealer told admitted to the mistake and re-applied both updates. The car (so far) is now back to normal.

P1433 denotes that the battery's capacity has dropped below 10% of its' original 6.5Ah
In other words, the battery is worn out.
Resetting the codes forces the car to re-evaluate the battery and it can initially take some time to return he same codes.
You need a new battery.

I just had my IMA battery replaced under warranty at 56000 miles. With the batteries failing back in Sept I took a 2200 mile trip including mountain terrain. I was amazed I averaged 46 mpg on this trip. My batteries failed about 2 weeks ago and Honda agreed to replace only if I would do the software update. I resisted but was told I had to get the flash or Honda would not honor anymore warranty which is still another 24000 miles. I had no choice but to agree...I have put 1700 miles on since and watched my mileage go to 39mph...the lowest ever. I fine in the city the auto stop works much better but on the hiway I get very little boost. Nothing like I got when the car was new. In other words so far my mileage has dropped from 43-46 to 39...very disappointing.

I have read many posts about the HCH 8yr-80,000 mile warranty on the IMA battery but I am unclear about one point. I want to know if the warranty is transferable to the second owner.I bought an 06 back in 09 and the IMA light has just started to light up. The code was poa7f.I hate going to dealers unless I know what I am talking about. I don`t want to start with them unless I know the battery is covered under this warranty. Also where can I find this information in writing outside of Honda ?
