I am a very unhappy Honda Civic Hybrid owner. Purchased the 2006 used with 32,000 miles. Used to average 40mpg with constant AC. Now average 33mpg without using AC at all. My Honda, plain and simple, has a bad battery pack, but Honda America isn’t interested in replacing it. This car gets worse gas mileage than the Echo I traded in to purchase the hybrid. On the plus side, my used Prius averages 45mpg. Spectacular. Boo to Honda.

“Drivers have also complained about a reduction in the battery’s ability to hold a charge.”

This seems typical for most of the batteries I’ve ever experience, be it laptop or other portable electronics, UPS (uninterruptible power supply) systems, and standard car batteries. Cells go bad, or loose their ability to hold a charge with use and age… why would a hybrid car’s battery pack be any different??

this kind of makes me appreciate the quality of prius.

hopefully honda can restore people’s faith in their civic hybrid line because insight and all other future honda hybrid sales will likely suffer because of this.

Honda IMA is actually a “mild” hybrid because the electric motor is not sufficient to drive the vehicle, even at low speeds. The electric motor in the Honda can only “assist” in acceleration.

With the Toyota/Ford “standard” hybrid solution, the electric motor can drive the vehicle for short periods at lower speeds.

The GM start/stop system should be called “light” hybrid….

I have a 2008 Civic Hybrid with about 40k on it that I bought new. I was getting about 48 mpg hwy and 41mpg city. We started noticing about a year ago that the battery wasn’t keeping it’s charge as well and when we would take it in all they would tell us is that it’s just the way we drive and it was normal.

Just before this last upgrade I started expierencing even more of a battery loss .

Since the update, the car drives like CRAP, it stalls out on you in the intersection and will not hardly go at all. The AC only cools part time.

The new update is a bunch of BS.

I’ve read that Honda has settled a class action lawsuit with a group of civic owners but only gave them $1000 towards another purchase on a honda. THAT is CRAP, you know the Civic you now have is worthless and you won’t get nothing for it when you trade it in or try to sell it.

It looks like HONDA has taken us all for a ride to the bank and we get NOTHING!

Sorry for the ranting but I am PISSED off. The ONLY reason I bought the Hybrid was for the gas mileage and now that’s gone!

We’ve been HAD…….

Well I just had my firmware updated this morning. Now I only have drove the car from the dealership to work. So I haven’t had much time to test the difference. But in my 5 min ride to work, I have noticed that I didn’t have any battery assist when I went over 2k rpm half the time. Also the head mechanic came out to talk to me about this. He wants me to drive the car around this weekend and report back to him on how the car “feels”. He didn’t want to tell me what he was looking for in case it put some notion in my head. Just wanted an honest opinion. Not sure what else he plans on doing for me. Will just have to wait and see.

I have a bit of a road trip tomorrow so I’ll report back if I find anything else.

For the record I have an 08 Hybrid that I have drove for 2 years now. The battery hasn’t been holding the charge as well as it did now for the last 6-8 months. I have seen the battery do it’s drain and recharge maintenance as high as 3 times in a month. And on hot summer days I will have minimal if any battery assist until the interior of the car has cooled down.

I just got the new Software update and My MPG sucks especially
in City driving. The loss of power is bad for pulling out into traffic and
I will have less power when it snows (not good).

I called my dealer and told them to place the old software back in.
They are giving me “we do not have the old version story”.
I told them I got 26MPG with the AC running in city driving.
Highway is less to 40MPG down from 42.5 to 45 on long highways trips.

The loss of power is harder on the engine to move my car.
I think the company should go back to the old software settings and
place a larger alternator on the car.

Does anyone know if the Honda Accord hybrid is using the same battery? I know, there aren’t many of us, but I can’t find any mention of our Accords being affected by faulty battery systems. And I was told by Honda that they weren’t going to discontinue this car before I bought it, so I can’t trust them to give me an honest answer.

If you think your civic hybrid poses safety issues due to this, log a safety complaint with NHTSA: http://www-odi.nhtsa.dot.gov/ivoq/

I have a 2007 Honda Civic Hybrid. I was getting 40 to 41 MPG until this update was done to my car 2 weeks ago. Now I am getting between 33 and 34 MPG.

I contacted Honda Customer Care Line today and they basically told me that the update was to make the car more efficient and that I need to relearn how to drive it.

After hearing that insulting statement, I indicated to the person from Honda that no one had to show me how to get 40 MPG when I got the car so what is it that I am not doing now. He was basically blowing me off and indicating that they are not going to do anything to put it back.

I have gone back to my dealership who totally gets it but cannot help me as their hands are tied. They are going to ask their regional manager if there is any course of action.

Does anyone out there have any advice? I am outraged.

We also have a 2008 Hybrid that we bought new that has just over 21,000 miles on it. Took it in for the software upgrade a few weeks ago. We now have very limited acceleration now. I almost got hit trying to accelerate onto the freeway. Acceleration kicks in when you are up to about 12 miles per hour. Gas mileage has lost about ten miles PER gallon. The electrical engine hardly kicks in so no doubt the pollution from the car is now as bad as any non-hybrid car. Took the car back to Honda today and they said we should put the highest octane gas in to fix the problem. Guess what? We have always put the highest octane gas in. They know what the problems are and aren’t willing to fix it. So now I have a car that drives like and old clunker and gets terrible gas mileage and pollutes just like any other car. I bought this car mostly because of the help to the environment. I hate this car now and agree with you that “We’ve been had!”

I just got the new Software update 2007 problam stat???

please
go back to the old software settings do not up date new software .
car going faster u can not slow down with out braks.

With all these problems being experienced why can’t a successful class action law suit be lodged against Honda? My 2006 Civic Hybrid seems to be working fine now after the software upgrade and a new battery pack. However, I had to pay half the cost because I was a few thousand miles over warranty. With a track record of defective battery packs, Honda should have to pay the total cost up to at least 100K miles.

This makes me so glad that I traded in my 2009 Civic Hybrid two weeks ago for a 2010 Prius II. Those two weeks have told me that the Toyota hybrid technology is vastly superior to Honda’s, plus the design of my Prius allows me to carry some cargo that I could never have carried in the Civic. The Civic was OK…but the Prius is terrific. Love it! Getting 51/52 mpg on a motor that has less than 500 miles on it.

And I thought I may have been the only one with this experience and problems.

I have a 2007 Civic Hybrid which I purchased new in 9/07. The car has 52,000 miles on it. At Honda’s request, I took it to my local Honda dealer for the software upgrade. I thought the car ran fine prior to the upgrade. I live in a very hilly area (the foothills of the Sierra Nevada Mountains at 3,200′ elevation). Ninety percent of my driving is up and down hills. Given the terrain I drive I averaged 38 mpg average, day in and day out. Hwy mileage averaged 42. When I replaced the OEM tires with new tires in 12/09, I took about a 10% “hit” on overall mileage but improved my vehicle’s handling tremendously (a worthwhile trade off).

NOW, after the software upgrade, my car is sluggish on takeoff, has a lag between when you put your foot on the accelerator and when the power “kicks in”, is slower to accelerate and just doesn’t perform as well as prior to the “upgrade”. I want my old software back!!! My Honda dealer service technician is well aware of my complaints and has notified Honda Corporate. I was advised the CVT software will “adapt” to my driving style and performance should improve over time (huh?). It hasn’t and it has been about more than a month since the upgrade.

I never had the battery problems as described by others here and, fortunately, due to our climate here, don’t use the A/C that often.

In short, my 2007 Civic Hybrid ran better and got better mileage prior to the software upgrade. I’m not satisfied. It makes me consider trading it for a new Civic EX. At least I’d get a sunroof with the EX…

Wow! Glad I hung onto my 2005 MT HCH-I. I was considering trading it in this year, but was made to reconsider and just drive it till it rusts into the ground, which is what I usually do. I have 110k miles on it and have never reset trip A and have an average of 55.6 mpg over the life of the car. Would be higher but I replaced the OEM Bridgestone B381s tires with Michelin Greens and took a 3-5 mpg hit, but am happy because they are more stable on winter roads than the B381s. Other than that I rarely push my SOC below 50% and always strive at having it full. 5 years now and no battery problems. (knock on wood)

Sorry to hear you HCH-2 owners are having all these frustrations and hopefully with this continued bad press Honda will get off their duffs and find a real fix to the issue.

I will drive this car until a viable, affordable, EV becomes available that I can charge using normal household current or it falls apart.

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? Especially, from the factory built original version?

2) If a Honda dealer flashes the ECM, will it potentially mask the P1433 code? Making AH 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? This obviously affects the performance (Power and fuel economy) and places greater wer and tear on the ICE powertrain?

4) Does anyone have experience with Honda’s Certified Used Car POWERTRAIN Warranty or Third-Party Warranties, with respect to premature IMA failures? I still have mileage and time remaining on my AH Certifed Used Car POWERTRAIN Warranty. Is the IMA Battery considered a POWERTRAIN component, or excluded because it is a battery?

5) Have any other Honda Civic Hybrid owners here joined the Class Action Suit against American Honda?

Any advice (or dare I say Insights?) would be greatly appreciated.

I’ve been having IMA problems for over a year. Honda tech told me my battery is shot but they can’t replace it under warranty because the IMA failure code hasn’t appeared. How convenient for them. Honda’s unofficial position is that if the code hasn’t come up, then all must be just fine. It’s pretty clear that Honda knows it has a problem on its hands with the batteries in the Civic Hybrids. Just look at all the complaints on the forums. This software patch is meant to delay battery failure until the warranty has run out by using the battery less, but it will reduce the amount of power that the car has as well as decrease the gas mileage. If it was possible to get the same gas mileage and power and use the hybrid system less Honda would have done that with the original design. So of course mileage will take a hit, as well as performance. It’s like they sold us a six cylinder engine and then put a software patch that makes it run on only four cylinders. Seems unethical if not illegal to me. I’m guessing Honda is expecting a class action suit out of this and gambling that it will cost them less than replacing many of the batteries under warranty. Is there anybody else (other than who has already posted a comment) who was denied a battery change under warranty (like I was) and was able to talk Honda into replacing it anyway? I don’t think we’re allowed to talk about class action suits on this forum but if anybody is interested in talking about other options via email, contact me at stephen@materaphoto.com. And let’s all make sure Honda knows we would never buy another Honda if this is how they treat their customers.

Hey man, I have a 2004 HCH Automatic. Bought it Honda Certified Used in 07 with 65k miles on it. I saw your posts here and on Greenhybrid.com.

My IMA and Engine light came on last week(P1433), so I made an appointment to get it checked out at the dealership.

Anyways the point I am making is that I live in California and my car is certified PZEV (partial zero emissions vehicle) and that status requires a warranty of 10 to 15 years on all emissions related parts.

So since i have a PZEV car the failing IMA Battery Assembly (P1433) that they recommend replacing is covered under warranty.

This warranty applies to PZEV cars owned/registered in California, Maine, Massachusetts, New York, and Vermont.

If you live in one of these states you can Email me at r_carvard@yahoo.com and I can send you a scan of the warranty parts list the service adviser gave me yesterday.

hope this helps.

I have a 2008 HCH with 47K and got the software update. Same story as most others on this thread. Combined gas mileage went from 41 to 35. Much less activity from the IMA. Now I’m Basically driving an underpowered 4-banger.
The dealer service reps (Curry Honda) insulted me. The rep from Honda America refuses to admit any problems.
I’m ready to sue.

As a owner of a HCH II 2007 and a hypermiler, I used to get 60+ MPG in the summer and 50+ MPG in the winter (Vancouver Canada). The overall average mileage for 3 years (~30000 miles, mostly on a 35 miles daily commute) was 55 MPG (with a 72 MPG high and a 50 MPG low). I was a very happy HCH owner… until the firmware update.

Now I get 45 MPG in the summer and below 40 MPG in the winter. I know, some people will say 40+ MPG is still a good number. No! It is not. My average summer commute after the upgrade was ~50 MPG compared with ~60 MPG for the same period last year.

What is worse is the loss of power — the engine feels so underpowered now. I consider this firmware upgrade a serious safety issue. If my life would depend on this engine delivering in a dangerous situation, I would likely get injured or even worse…
I’ve got almost stuck several times trying to go uphill from stop lights in intersections and got honked by other drivers who could not understand what the heck is going wrong with me or my car.

Very disappointed. I’m seriously considering selling this car for good if Honda does not come with a real solution in the near future.

Honda screwed us big time with this one…

The behaviour reported in this post is e-x-a-c-t-l-y what we are experiencing. The firmware update pretty much made the extra premium we paid to have a Civic Hybrid instead of a standard Civic a big waste of money. Up until now, I’ve been a very loyal Honda customer, but that will change if they do not address this problem.

honda cra does have mileage issues but then with proper maintainance you can extract good mileage from them

trye batteries have a lifetime , after that a hybrid car’s battery or any other for that matter won’t give good service

am sure they’ll come with better batteries in the upcoming editions. honda is a major brand after all

having said that , the assist in honda hybrid is good

you indeed have every reason to be pissed and honda cars are known for battery related hiccups ; however i hope it’ll resolve the issue in coming editions

My daughter went to her local Honda dealer in Montreal, Canada and was told she needed the upgrade, and charged her $100.00 for it. I have not seen anywhere that there was a charge for this, and think that once again, a female got taken by a fear tactic. Lucky for them that I live in Ohio. Is there a phone number she can call to get someone’s butt in a sling??

I have a 2006 HCH and my wife has a 2005 HCH. Although our commutes cover different terrain, she has always gotten better mileage that I have. Her’s is a manual too, by the way. She consistently gets about 47 MPG, mine has never topped 42 MPG.

I stupidly took Honda up on their offer to update the IMA software. I knew it was a crap shot. Well, I lost the gamble:

Specifically:
1. The car now feels totally under-powered. It doesn’t have them responsiveness as it did before.
2. When starting “off the line” there is a lag of about a second. When you press on the accelerator from a full-stop, it’s almost like it’s not “listening” to your request to “hurry and move the hell on” from me.
3. As others have stated, this is really bad when your trying to do a start while on an incline. I can see how this is a SAFETY ISSUE (can you see this, Honda?). If I am on a hill with people lined up after me and I’m on a hill (not even that steep either,mind you) and I try to accelerate I get that sinking feel that the car has just died, but because I’m moving a little, the car in back of me thinks I’m moving. I see a rear-end collision being caused because of this. To make matters worse, because there is not enough power available, the car can actually move backwards a little. Yikes.
4. My mileage has never been anything near to what Honda claimed. But I was OK with topping out at a little over 40+ MPG. I also had a nice responsive car too with a lot of zip (much more than my wife’s 2005 HCH). Now with the software update I am getting about 30 MPG and it’s seem to be getting worse, not better. How’s that for “learning” my driving patten?
5. The IMA battery is charges up very quickly; almost suspiciously quickly. But it’s like a faux-charge. The indicator says it’s full. But the minute the IMA kicks in to use the battery reserve several ticks are taken off the gauge. This can be caused from simple accelerations (for a few seconds) while moving, or from going from a dead-stop to a start. I used to maintain a relative high-level of IMA battery reserve and rarely get down to two “ticks”. It’s not unusual for me to be running at near-empty on the battery guage, which further adds anxiety to my drives. Without the IMA power, you’ve got a nearly useless car that may malfunction altogether.
6. In general, I don’t like the car anymore. It used to be fun to drive, but it isn’t anymore. I feel like Honda is incompetent and isn’t playing straight up with its customer (remember, I bought TWO of their products).

I plan on trading the car in and getting a non-hybrid vehicle. I would probably get better mileage with a compact Ford and not have to worry about all the battery BS. Let someone else be beta testers for new technology; I’ve learned my lesson.

If anyone can tell me how to revert back to the old version of the software I’d appreciate it.

The IMA light is on, your Car is still in warranty, return Car to a Honda Dealer, they will have to repair the Car at Honda’s expense. Do not attempt to erase the IMA code by disconnecting the 12V Battery or allowing the 12Volt Battery to go flat. Honda need to see the Ima error light to pursue a Warranty repair claim

I purchased a 2008 Honda Civic Hybrid, and late last year (2010) I had the IMA update installed, like many others have done. Honda service techs told me it was essential to have this update done. After that work was done along with an major service, I noticed that my mileage went down below 40mpg. At first, I thought, this is normal, and the engine just has to get back in sync. After several miles of driving, I noticed my mpg was either getting worst and never better.

I could have purchased a regular Civic and paid less for the car in that case. What a rip off by Honda. This IMA upgrade made all my mpg go right down the drain, what’s the deal? When the car was new, I took a long trip down California, approximately 300 miles away, and was receiving well over 50 mpg. Not anymore, that upgrade/update completely ruined any great hybrid mileage I use to have.

I want a refund, and a new car for all my troubles. I know Honda will not do anything about this issue, since they don’t even know how to fix this issue, but they must listen to those who have purchased their product for what was advertised as mid to high mpg from their product.

I”m pissed to say the least, and the service folks, gave me a number to call and complain, but said they could not help me otherwise.

Where can I make a formal complaint?

Help.

I’m joining the disappointed club. I have a 2006 Civic Hybrid that was working great until I brought it in for the IMA update last year. I was assured at Honda Service it was a software update and wouldn’t affect my car’s mileage or performance. Performance remains good, but my mileage promptly dropped from 42 mpg highway to about 37. I’ve been driving it now several months and the mileage isn’t going up. My battery had been working fine before the update (at about 53,000 miles). I haven’t had other performance issues, but when I bought my car in 2007 I plunked down another grand or so for an extended warranty, on the buzz at the time that the batteries could wear out around 80,000 miles. Now I feel I should’ve saved that money, because the update will likely extend battery life by decreasing functionality. If I go Hybrid for my next car I’m getting a Prius.

i just purchased a 2008 civic hybrid and i am happy with my mileage. the car had 63500 miles when i bought it and i am getting 48 mpg on hwy. the one thing i have noticed is that i figured the mileage the old fashioned way by hand. the in car computer shows mileage is off by about 10 mpg only showing about 38 mpg. i will continue to monitor this and see what develops and will be back to report. i will also monitor just city and combined driving. i normally drive about 50/50 mix of highway and city.

comment and friend me, pass it on. We Have an damn good case.
lets go to work!

The first two year of owing my 2008 civic hybrid I averaged 42mgp on 30,000 miles. I then began having problems (34mpg) and notified the dealership who told me I didn’t know how to drive a hybrid. Then the software update came and I was the first in Tulsa to have it installed. It brought my mpg down to 30 with the battery charging most of the driving time. I returned to the dealership where they reloaded the software to fix the problem. Then they said they couldn’t do anything else and I would have to call Honda. After calling Honda they again told me I didn’t know how to drive a Hybrid and the car was operating normally. Because the IMA light doesn’t come on there are no problems according to Honda…..BS.

I think that I would be better off is the hybrid system didn’t function at all because of its constant charging while driving, especially on hot day.

I’ve been monitoring this for some time but have been reluctant to have the software installed. Last week I took my 2008 in for an a/c leak and they put the software fix on while it was there. My mileage dropped from 42 to 34 mpg. If anyone knows of a lawyer that is interested in bringing a class action suit, I’ll join in. This kind of mileage isn’t the reason I bought this car. I would’ve thought Honda would own up to it and replace the defective batteries, but they are not the old Honda I used to trust. Guess it time to find another car company where reputation means something.

Went to the Honda dealer last week for an oil change in my 2007 Civic Hybrid. They told me that there was a service update that I needed so I said sure. Apparently it was the software upgrade that I’ve been reading about here. Now I’m getting 26mpg. The battery is almost NEVER charged. It sits around two bars most of the time. The battery will suddenly go to complete charge (you can actually watch the bars go up) and then completely discharge in less than two miles.
I never had this problem before and the car used to run great. Now it sounds like the engine is constantly straining.
How do I get the software “update” reverted back to the way it used to be??

My car has been whining and rolling backwards since day 1 of purchase. Does anyone else have this problem. The dealership said the noise is from the transmission. Other shops say the charging system that is located above the transmission. Any opinions out there?

Three days ago I took my 2007 Honda Hybrid to Honda because my IMA light was on. They gave me my software updates. On my way home, the lights came back on the next day I took my car back up to Honda. They then told me that my IMA battery is shot. They said that it will be $3025.00 to replace. I wish I would have read all that was out there about this car before I purchased it. Beng a single mom who works fulll time, I now have to figure out how to pay for this. They told me it would be fine to drive for now, but when I try to get on the road the car has no power and I almost get stuck in the road. Its a death trap!!! Nothing I would want to drive my son around in. I work full time and with rent, car payment and other bills, $3025.00 is no where near my reach. Thank you Honda for holding your customers in such a loving grasp, thank you for being so responsible thank you for being such a life changing experence for me!!!

I have a 2009 Honda Civic Hybrid I bought new in March of 09. I have about 25K miles on it, and just last week the engine light, and the IMA light came on. I brought it to the dealer, they did some tests, and consulted with Honda after they got the results. The dealer told me the battery was shot, but had to wait for Honda to get back to them on whether they would honor the warranty. I found that strange and kind of ticked me off.

Anyway after a few days they got back to me and said yes Honda will replace the battery free of charge. So today I’m driving one of the dealerships loaner cars and expect to pick mine up tonight.

I have a really bad feeling about the whole experience though, under 3 years driving, 25K miles, and the $3500 battery is no good?

What happens when this happens to me next year or the year after and I have no warranty. Depending on the outcome of that last statement will determine if I ever buy a Honda again.

if you are under warranty still, file a BBB arbitration case and/or small claims court. Honda will discuss options about bringing your car into a dealership for them to do a diagnostic. Honda won’t do anything until you file something to force their hand. when at the service, make sure they get a reading of what your usable battery is. if it’s getting to 20%, then the battery is ready to go. i had to go through this for over a year of BBB arbitration, multiple calls, and then finally a small claims court filing and serving those buttheads because the Honda engineers continue to say that the drain is normal. continue to badger these folks and tell them that it’s normal if it’s infrequent enough, but it’s not when it happens multiple times a day. just like a computer, it’s normal for it to crash once in a while (1,2,3,4 weeks), but should not be crashing every 10 minutes and having to reboot all the time, which is what your car symptom probably is…much more frequent than what the manual says “may” discharge.
good luck

I love my honda civic hybrid 2007 european-asian model. I made 68 mpg with the software update! I have the battery level at full!!! untill now i have 90.000 km

im glad to be owner of the last generation of honda civic hybrid with NiMH battery pack. The battery is most good than ion-litio. and most expenseve tehnology

why just in USA is happening this?

I have 2007 hch with 55000 miles. It had the software “update”.

The other day I went over 6000 rpm trying to accelerate to about 65 over about a one-mile distance so I could get into the next lane, ahead of slow traffic, before my lane turned exit only.

The next day it went over 5000 rpm just to get my speed up to 45 (forty-five!) so I could safely merge onto the highway.

I think I’m going to write a certified letter to Honda holding them liable for any injuries that occur to me or others while I’m driving my car that occur when I’m unable to respond safely by maneuvering in traffic.

I’m about to have my IMA battery replaced for free by Honda but I am concerned that the replacement will fail. Anyone have comments about the replacement batteries being installed at the dealerships?

technically, your warranty should last to 84k as there was some mileage suit that said that civic was overstating the mileage by 5%. the class action has an item that says the warranty would be extended another 12 months/12k miles, whichever comes first (if you choose to accept the class action).
the software is a joke as a spokesperson was quoted as saying “the software upgrade is intended to extend the battery life beyond the warranty”. so in other words, they are just prolonging the inevitable and you will be on the hook for a new battery.
as for $5k. not sure if that’s real cuz the older 2006 NiCad replacements in SF Bay area dealership is ~$2.5k with installation/labor included.

I also have a Honda Civic Hybrid it is a 2008. I do feel like the mileage has dropped (36.6mpg) , the car start like a regular car always in the morning when i get ready to go to work this problem beging in Mid January, the speed is very poor for 10 mint. and My car has no power and my battery is usually around two bars ,The battery will suddenly go to complete charge (you can actually watch the bars go up) and then completely discharge in less than I reach the stop light and all this happen when software update was done in November 2011.

I have 2009 HCH. IMA and check engine light came on last 10/2012. Dealer updated the software which decreased my mpg from 38 to 32. Four months later, IMA and check engine light came on again. Today, my IMA battery and IMA motor were replaced for free. I hope this will last long until I will sell or trade in this car. I will still the American Honda Motor to small claims court.

My 2008 [Civic Hybrid] purchased new started having these problems about 6 months ago. Now Honda reprogrammed the software. Made it even worse.”Top VPS Hosting

I am so glad I read everyone’s comments. I was planning on purchasing a 2008 honda civic hybrid with 53,000 miles tomorrow and I just had a bad feeling tonight and went online for more research and found this site. The car must have had the update since I experienced the no power thing while test driving. I highly doubt I will be purchasing and am very grateful for everyone’s input. What a bunch of sneaky b*stards honda are for this B.S update.

My 2006 HCH has all the same issues everyone else is reporting here.. “software update” made it even worse.. They’re clueless about how to handle it.. it’s just the new “normal.”

I bought a used 09 Civic Hybrid I immediately started having IMA problems with. Software updates were done which only made the problems worse. Honda finally agreed to replace the battery. I noticed an immediate improvement with mileage until summer came. I started using the A/C more and noticed that the mileage was lower and the IMA battery gauge was consistently registering on the lower end and the IMA assist was feeling really bogged down. I can accept lower mileage with the A/C on, but does or should the assist suffer so much also?

Most people can attest to the fact that setting clear boundaries between personal life & work matters is a good idea. If you work at home, all the more reason you must know how to manage your time and focus on your priorities.
