#545 of 1530 Problems after software change on battery computer
Aug 27, 2010 (8:36 am)
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.

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.

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!

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.
