When I received my letter and phone call from American Honda early in early August encouraging me to have my IMA software updated to extend the IMA battery life, I complied the very next day. Shortly thereafter my 2006 Civic Hybrid with 110,000 mi. on began to experience IMA problems. Battery charge would drop to 2 or 3 bars and the car would have extremely poor acceleration, within a minute the battery would be a full charge almost immediately with acceleration back to normal. I returned to the dealership and informed them of the performance issue after the software update. For the record my Honda ran great even with all the miles on it and would recommend it to anyone until the update. The dealer said there were no issues and the car was operating fine. I objected and asked to have the old IMA software reinstalled, the dealer said they could not. I put the dealer on notice that this problem was a safety issue more than a performance issue. If you can not trust your car to accelerate when merging onto a highway or make a left turn from a complete stop what good is it. I prohibited my teen new driver from using the Civic. I next called American Honda's Consumer Complaint hotline and filed a complaint with them they said they would investigate. After a couple of days Honda called me to inform me the car was operating fine. I again objected and and asked them if I was on recorded line, they said yes. I put them on notice that if anything happen to me or one of family members American Honda was responsible. To make a long story short, two weeks ago the dealer calls and asked me to bring the car in for a district manager to test drive. They also stated Honda was having some issues with the software patch...oh really. My wife and I began keeping a log of when the problem occurred, battery charge level, mileage, time of day, and outdoor temperature. We gave them a copy of the log. After several days(they supplied a rental) of the dealer going to bat for me, Honda relented and installed a BRAND NEW IMA BATTERY with the old version of the IMA system software. While we have only had the car back to us a few days, my wife has commented that it drives like a new car. Thank you Honda for coming to your senses before somebody was injured or worse. I believe it only will be a matter of time before Honda issues a mass "good will" IMA battery replacement.

Thanks for this very worthwhile information. Do you think the "goodwill" effort will include rebates for us who paid at least half the cost of the new IMA battery?

Like many I had my upgrade back in July. Since then my IMA will not work all the time. What I mean by this is NOT what they outline in the letter. If I merge onto the freeway/highway and try to accelerate my IMA should kick in, but it doesn't, not at all. Then next time it will work again. I drive up the same long steep hill every day, some days my assist kicks in and everything is great, some days it does not and I have a pile of cars behind me.
My friends at Darryl Waltrip Honda in Franklin are telling me that what I'm describing is exactly how it works now. All the way up to the service manager, "this is how the car works".
1 - They asked me to do this upgrade, my car didn't have any issues before.
2 - The "upgrade" letter did not mention 'sometimes it works and sometimes it doesn't'. I certainly wouldn't do the upgrade if it did.
3 - Really? If you make it so my IMA only kicks in 80% of the time that will increase the life span? That does not sound like an upgrade, sounds like a bunch of crap.
4 - For 2 weeks after the upgrade I did experience a drastic loss in MPG, from 42 ish down to 30. The 3rd time I took it in that problem stopped. They said they did nothing.
I have owned Honda's my entire life (36 years). My mom worked for Honda out in Oregon. This is my last Honda. I cannot bleieve someone can look me straight in the face and tell me that sometimes it works and sometimes it doesn't.
If anyone is interested in a car, I'm selling. It works exactly as Honda says it should.

What I would be curious to know is what is the difference in the battery state of charge when it works and when it doesn't work.

I have filed a complaint with Honda Customer Relations and I took it to the dealer and he test drove it. He said he couldn't duplicate my frequent discharge of my IMA battery. I called Honda Customer Relations and complained again about the IMA battery and also said the software update made the car unsafe and I wanted the old software installed. Honda said that they couldn't reinstall the old software and I would have to take it to the dealer to have them back up my claim that the car is unsafe because of the frequent discharges and the software update. Honda said I had the option to take it to another dealer to get a second opinion. Honda also said which made me really angry that the dealer could charge me for their time test driving the car if they couldn't duplicate my problems.

I'm desperate to improve the performance of my 06 Hybrid which has been discharging frequently and the software update made it more sluggish. I filled up with mid octane gas yesterday. My impression after 1 day of driving is the engine seems peppier and the integration between the gas and electric engine seems better. I'll see if this continues.

Yeah, they made that same threat to me. I pitched a fit. And of course, Honda Customer Relations told you that they haven't heard this complaint from anybody else? LOL

Problem! what problem?
\Even if a hybrid battery fails outside the warranty limits, Toyota would most likely still offer assistance, said Pearce.
It's the same story over at Honda, maker of the oldest hybrid on the market, the Honda Insight.
That's nice... what about the Brooklyn bridge.
Don't sweat over hybrid battery failure
#636 of 1535 IMA battery flaw and repair
Sep 27, 2010 (6:44 am)
This mechanic repairs IMA batteries for far less than buying a brand new set http://www.hybrid-battery-repair.com/hch/index.html. If you read his webpage, he says that the IMA batteries tend to deteriorate early in hot weather. My interpretation is that Honda did not do enough testing of these IMA batteries in hot weather, or should have had a cooling system installed for the battery pack. (My understanding is that the Focus hybrid battery pack is kept at 70 degrees to help it last.) I would be curious if there was data on Civics hybrids with freqent recals and IMA battery replacement by region.
