Honda Civic Hybrid IMA Problems

    > What I can't figure-out, is why my mileage is going-up when I seem to be relying on the gas engine significantly more than before.

    The most likely reason is that your car used to spend a large amount of energy charging the battery. Now that it is functioning better, it accepts more of the charge and therefore costs less mpg to charge it.

    Time will tell, but recals don't only happen when a battery gets worse, they happen whenever the capacity is different than it was. If your battery is gradually improving, it will recal whenever it discovers this. Let's see what happens in the fall.
  • Do not have the update installed. I did only to find that the gas mileage and battery assist is greatly reduced. Today, 8/20, my honda was back in the shop because of the adverse affects of the upgrade only to be informed that "even our regional honda corporate guy is upset with the upgrade on his company car". When the service tech approach the regional rep about my car and started to tell him about my complaint of power loss, he responded "and I guess his gas mileage is also affected".
    The dealership explained to me that unfortunately they cannot do anything about the issue and that they have to write on the service report "car is performing as per specifications".

    Time to sell the HONDA!

    Is Honda still keeping quiet?

    They must be having some heated meetings about this problem. I'd like to think that they won't bury their heads in the sand and keep us stranded. I don't see any winners with this scenario. If they don't improve the IMA battery then they are doomed, doesn't the Insight car use the same type battery. Toyota is coming out clean, Honda should follow suit. Man! if you can not trust your Honda, then we are doomed. You know you get crap when you buy Chinese products, Japanese is supposed to be quality.I'll go back to GM, at least parts are cheaper and more available. my 2 cents.

    If we file a complaint with NHTSA, I wonder if that affects the trade-in value of our cars via the VIN number? As previously mentioned, my mileage with the update has improved, but the non-availability of assist, is at times, very disturbing. I'm also wondering how much my battery deteriorated in the almost 2 and 1/2 years prior to the update?

    I was hoping to keep this car for a long time and am concerned that Honda battery participation goes down to (I believe) to 60% of the price after 3 years.
  • I had my car in multiple times and finally decided to take the loss and trade the vehicle. I did not feel comfortable selling the car outright, and did not really feel great about trading it either but decided that was the way to go. The acceleration was simply unacceptable without the IMA working, which was happening EVERY time I drove the car. I took many videos of this happening and gave a copy to my dealer here in Cleveland. Hopefully they passed it on to the "factory rep." Even if they had replaced the battery, I cannot afford to do so out of warranty every couple of years!

    As I was about to trade the car to another dealership, the dealer I bought the Honda from called and said they would prefer to buy the car back. I got high trade in value, which was a little better than I would have done, but still a far cry from private sale value and even further from retail.

    I cannot tell you the relief I felt once I was done with this ordeal. I figure it cost me about $450 per month to own this car. Shame on Honda!

    Be sure to check out the LA Times article from August 13th. The Emissions Board in California is going after Honda for issuing the software update (which affects mileage and performance) without consulting them. I guess that with the updated software, these cares may be in violation of emissions standards. So much for GREEN!
  • Did you get your full purchase price, and did you have to buy another Honday?

    I think all States have their own lemon law repurchase rules but here in Maine it is: Provide your original purchase agreement with all mandatory fees (including doc fee and sales tax) and from this amount deduct the lowest of either of the following 2 calculations: 10% of the total purchase price OR (.55 cents / 3) x mileage at time of arbitration. I had less than 10,000 miles on the car in the 34 months before arbitration so my deduction was just a little less than $1,800! The 55 cents is the amount IRS allows per mile for business use. The 10% allowance would have been around $2,500 so it was the $1,800 used for the deduction from the total purchase price. I am VERY happy with the repurchase payment and also of having the experience of owning a hybrid. I will NOT purchase another hybrid or any all electric vehicle for many years to come. I have not purchased another car yet, want to see what the Chevy Cruse is all about.

    For those of you having battery problems, SoC recals many times a day and you still have time remaining on your 36 mo/36,000 bumper to bumper warranty then I would get an application from the Better Business Bureau Auto Line (phone # in your consumer info manual) and start a case against Honda. In my opinion, Honda does not have a leg to stand on. The car is not operating the same way it did when you purchased it and it becomes unsafe when in recal mode with no assist. The BBB process is not fun but it was worth it. You do not need an attorney but you will have to present your case yourself at the hearing. If you do file with the BBB make sure you insist that you want to go to arbitration.
  • The civic owners may have to know the following things:

    1. What are the mpg and power capability after the software being updated.
    2. What kind of possible damages to the car battery cell/pack may have occurred, and to what degree.
    3. Any way to test or prove if the battery degradation is within normal levels or not. Some degradation is recoverable but some are permant. And normal battery degradation won't affect mpg too much.
    4. How to affect the driving ability typically in cold-weather, like winter time in Cleverland or Cananda.
    5. Details about the software update: such as the possible changes in battery regen/accelerating power limits, battery cell rebalancing functionality, cold weather drivebility, shallower battery charge/discharge cycling.

    The car owner may also be curious about other information like: the labelled mpg/power stick to the windows of the 2011 model civic hybrids, which have the same battery and updated software pack, because reduced usage/power of battery pack may affect mpg, as some old posts indicated.

    Congrats! I did the same thing, traded in my 2006 HCH at the dealer where I bought the car for much higher than any other offer I had. They are currently reselling my old car with 72K miles for about $14,500. I wonder if they replaced the battery?

    I own a 2008 civic hybrid and brought the car in for the battery computer replacement a few weeks ago. Not only did I have a drastic decrease in mileage, the car has decreased in power going up hills. It failed on me driving up an incline inwhich I lost total power and was going downhill backwards while it was in low gear. I had my family in the car and it scared the heck out of all of us because this has never happened before. I am grateful to the person behind us when she saw us coming down she backdown immediately to give us room until I could get control of the car again. I am now driving farther to avoid hills in this car and am really disappointed with the performance. I took the car back to the dealership and the technician said that it is normal for the car to be slow going up hills because of the small engine. During a test drive we took the car up the same hill and it barely made it at 5mph. I did have four of us in the car when it failed. But before the computer change the car use to go up that hill at over 15mph. And now I have to avoid it. I hope others do not experience what I am going through right now, but if they do I hope they make sure that they check behind them for cars before they go uphills. I wish I have never bought this car and got a regular civic since I am getting the equivalent mileage as one. All the extra money I spent was wasted on buying this hybrid. Honda should be up front about these problems before people start getting injured and fix these problems immediately. Toyota did!!!

    Obviously, your are not getting battery assist going up the hill. Since the new software requires a higher state of charge (SOC) before allowing the battery assist, you need to make sure your SOC is 7 or 8 bars before taking on a steep hill. If it is four or less bars you will get no assist. Before, you could get some assist down to two bars.
  • pmzpmz Posts: 26
    So before you go up the hill, put the car in park and idle at 3500 RPM until you get 6 or 7 bars. Proceed.
  • bosslessbossless Posts: 179
    Don't stop and idle at the beginning of the hill because then there is no room for a running start.

    Better yet, call a tow company and have your car attached to it for the ride up the hill. You will be astounded at the improvement in your mileage!
  • bosslessbossless Posts: 179
    What about the tow truck milage which you will be paying for?
  • I sympathize with your loss of power and Honda is to blame. One possible workaround is to put your transmission in "S" to keep it in low gear as you climb the hill.
  • My situation is similar to the Floridian with the 2006. My IMA light was not on but it was recal-ing at least once a day. The software update seems to improve the situation a bit, but my 2006 continues to recal almost every morning and sometimes 2x a day. The difference is it recals at 2 or 3 bars instead of 1 bar with the previous software.
  • I have a 2006 Honda Civic Hybrid with 70,000 k on it. My warranty is good for another 3 years and the warranty on the battery is for another 4 years. Why would I want to get this upgrade that labotomizes my car's IMA system. I have had no problems with the car. I have had the once in a blue moon recals done but not like what other people are saying. I really liked that car until I started reading online how much people have had trouble with the battery. When I bought the car I thought surely Honda would stand behind there warranties. I refuse to get this new software update. I called Honda's Customer Relations line and they say that if I don't get the update it does not effect the warranty that came with the car when I bought it. When I called back to get them to fax me that in writing (Because Portland Street Honda my dealership was unaware of this) they said no "no we are unable to provide you that promise in a letter". So basically saying you'll just have to trust a CSR from Honda Relations saying that it won't effect the warranty if I refuse the update. I have launched a complaint with the Better Business Bureau and suggest anyone on here with a HCH do the same thing. The only way something will get done about this is if we get a higher power involved.

    If you are planning to keep the car beyond the warranty period, I would recommend that you get the update. If your battery is good, I don't think you will notice hardly any difference in your milage with the update and you will give the battery longevity.
