#319 of 1535 Just got my IMA battery replaced
Apr 20, 2010 (9:47 am)
I had mentioned earlier that my 2007 (purchased 12-06) Civic Hybrid with 120K miles had a couple of incidents where if I don't drive it for longer than a few days, the front battery is necessary to start the car and then the IMA light comes on. In other words, there appeared to be a self discharge. After a couple days (I commute 45 miles each way) the light goes off and everything is OK. In my entire time of owning the car, I have NEVER got mileage below 40mpg.. Typically I get 43 or so. I also find that the car's mileage estimate either match or are slightly pessimistic to the values that I calculate using the old fashion calculation.
I'm also confident that if I drive 55 or so, I can get 50mpg.
During the last service, I mentioned the IMA light incidents (I think that there were 3 or 4), they tested the battery, and then determined that the battery was "deteriorated." I tried to get info from them. Apparently the car gives them a thumbs up or thumbs down. They don't do any testing of the battery directly.
Well, in CA, ALL emissions equipment has a mandatory 150K or 10 year warranty. Since I was "only" at 120K, they said that they would change it. For free! Which they did. The service rep said that in the entire time that he's worked there, Honda has covered EVERY SINGLE IMA BATTERY REPLACEMENT whether in warranty or otherwise (that he knows of). So it's never costed their customers a nickel.
This has made me become skeptical of the many posts that I see here, particularly from dealers in CA, that they are double dipping on the repair. Or are just lazy.
They also did 4 firmware upgrades. The behavior seems to less aggressively use the battery, although I did not notice any significant performance change (other than my mileage improving a bit). You notice the electric assist most when coming form a stop, where the Atkinson engine shows it's miserable torque...At any rate, I've decided that I really like my dealer after reading all the crap from others.. (Livermore Honda).

And put the toxic metals into the ground?
At a minimum it should go to a recycling facility as the NiMH batteries are almost 100% recyclable.
Again, I buy bad batteries for parts.

Please don't suggest that the rest of us are liars. There are way too many of us who have had bad experiences, and whose mileage has dropped to the 27-29 mpg range, for us all to be nuts. I'm happy for you, if that was not your experience. But please keep your skepticism about our problems to yourself...and I'll try not to be skeptical that you work for Honda....

Hi, I have had a similar problem after experiencing a flat battery, but I'm not sure of the cause of the flat battery.
I drive a 2006 IMA model which has covered about 85k miles.
When I found I had a flat battery I jumped started the car and likewise the recharge circuit wouldn't operate.
The green drive indicator light flashed like a Christmas light, the engine management light and various other lights stayed illuminated with the engine running.
I had the car towed to Honda dealer, they apparently recharged the 12volt battery and told me they had to reset the engine management system! (As per Honda procedure I was told).
For this I was charged £100 or about $150 dollars!
I asked why I had to pay this amount for what was essential a flat battery and asked for the diagnostic report which they would not provide me with.
I was told as the system voltage dropped below 10.5 volts this caused a problem, of course I asked surely like any PC manufacturer the system would hold its values just like BIOS in PC?
I persisted with my questioning and reasoned with them that then every time I was to get a flat battery of disconnect the battery I would have to have a system reset and pay £100 and this was wrong and their must be a firmware / software problem.
I was told I should write to Honda directly and my monies were refunded and I was asked to leave the premises.

Another problem I have had is brake fade as result of the system voltage I was told dropping below 10.5 volts.
I approached a junction and braked to stop and brakes failed to operate correctly, as a result I overshot the junction by about 3 feet, thankfully no vehicles were passing at that moment.
The Honda Dealer (UK) told me there was a brake error code found and this had been caused by the system voltage dropping.
They reset the faults test drove the car and told me all was fine! Since this I have had another two occasions where I have had problems again.
Anybody else experienced this type of problem?

You obviously misread my post. I was implying that the other Honda dealers were liars, not the users!!! Go back and read my post. And I accept your apology in advance!!

As an update, my car definitely behaves differently after the 4 firmware upgrades.
The battery is used aggressively at low speed and from the start. Other than that, it seems as though it's trying harder to keep the battery at a higher charge level. My charge gauge has not gone to zero even once going up my long hill on my commute. I don't think this is due to increased capacity. I think that it chooses to use the engine instead, perhaps "saving" the remainder of the battery for a "start from stop" situation? Before, it'd drain it all the way which essentially maximized the advantage going up and down hills (at least by my thinking). That being said, I haven't really seen much of a change. I guess that it's worked so far because I don't recall one incident of "no starting power" since the ima battery change. Perhaps a slight increase in mileage--I used to average 41,42 and now it's 42,43 according the the average mpg gauge.

I have posted a few times about my 2006 Civic Hybrid with 37k miles and the concern with the battery, charging system, bogus software updates and terrible factory service. I pulled into the dealer on Thursday with a car in forced regen, no IMA battery, and using the standard starter to start the engine. I had the service writer and tech observe these conditions.
I had the writer and tech ride with me and had them observe the rapid charge and more importantly the rapid discharge of the IMA system and the lack of power once the battery is kaput. I had them observe how the car jumps when it is in autostop at a light and then suddenly start and go into a 1500 rpm forced regen. They agreed all was not right though there was no IMA light on.
I left the car with them and said I want my Civic back like it was for the first 2 years that I had it and not this disappointing, underpowered, used to be good car.
3 hours later I received a call from the Service Manager stating......there was no problem as the IMA light was not on. I am beyond angry at this point. It sure was nice the software patches that were installed removed the P07AF battery deterioration code and made my car even less a Hybrid...
I got right on the phone with Honda and used my contact number that I was issued last September when this process started. I left a message for the rep stating my disappointment and how I had jumped all the hoops in meeting with the factory engineer, etc.
I also mentioned the many exact same concerns with this vehicle that I and many people on this and other message boards are dealing with that I have seen on the NTSB website, yes the site that took Toyota to task. 10 minutes later I received a call from American Honda stating they had contacted the dealer and a battery had been ordered, do I need a loaner car?
The battery will go in next week and I can sell the beast with a good conscious. Not sure what to replace the car with the new Jetta diesel is looking pretty good.
Good luck to all of you and hang tough.

That reset consisted of plugging in a scan tool and clicking reset and then getting into the car and revving the engine to 3500 rpm for about 2 minutes.

I had the exact same problem with my hybrid last year. Went to the dealer, they told me they'd need to replace the battery etc. The IMA light was on and it was draining my battery so the car wouldn't start. I finally took my car to an independent garage that specializes in hybrids. I live in San Francisco and went to Luscious Garage. I know, hybrid specialists are rare and I'm grateful I took a chance and went there.
They told me the problem had nothing to do with my IMA system but it was a problem with the A/C. At first I thought they had no idea what they were talking about but, I kept listening. They explained that it's a very common problem with the honda hybrids and that there's a part on the A/C system that doesn't shut quite properly over time causing the IMA system to think the A/C is still running. Consequently, even though the engine is off, the electric battery still thinks the a/c needs power and it drains both the IMA and the regular battery.
They changed the part and I left the garage a few hours later having been charged $65. Brilliant!
The problem stopped and my car now runs like new. Hasn't cause problems ever since. One sign might also be that the A/C doesn't run as cold as usual. I've had few problems with my car but the ones I've had somehow are all linked to the A/C...again, according to the dealer "that's normal on civic hybrids 04"... really? should have mentioned that on the sticker when I bought the car...
Hope this help.
