#686 of 1535 Honda Integrity?
Oct 08, 2010 (9:58 am)
We had our 2008 software upgrade and Immediately had problems. Went to dealer and gave this list.
September 29, 2010
These are the problems that are occurring with our 08.
1. 2008 HCH batteries charging and discharging erratically
2. Acceleration response is erratic, I either get the assist or I don't regardless of the level of charge on the battery. In a couple cases it seemed as if the car did not want to accelerate from a stopped position. This has put me in a dangerous situation more than once when trying to cross an intersection.
3. How is it that the IMA batteries ( 40-50 % charge) are assisting with engine acceleration if Assist indicator has no bars? This is telling me either the software patch isn't working or the batteries are failing or both.
4. My fuel efficiency has not improved and instead I am seeing less MPG from 48 mpg to 32 mpg, same as a non-hybrid.
5. Basically, the update has placed more burdens on the very small gas engine to power the vehicle with much less assist from the electric motor than before the update. Battery does not charge as high a level as before and rarely drops the batter below 4 bars. At 4 bars the electric assist is unpredictable, sometime working and sometimes stopping the assist at the worst times, like in the middle of passing or on a highway on ramp. Try getting up to speed on a highway on ramp with the small gas motor. Won't happen without the assist, to me, a safety hazard.
6. My wife is now afraid to drive it, thanks to Hondas battery saving update. Honda has turned my HCH into a standard underpowered Civic. I paid an extra $5000 for the hybrid feature.
Just because a voltage level looks ok does not mean the current output will be Ok.
All we want is the car to drive the same as when we bought it. There are many examples of these problems if you go to the Internet and check (http://www.hybridcars.com/forums/civic-hybrid-battery-ima-problems)
Ps: please attach this to your work sheet so we will both have same records.
Result No Problem Found from Honda Corp.

You seem to have for sure a bad battery. Maybe other problems too. Have you ever had the IMA light come on? Honda generally accepts that as an indicator for a new battery.

I tested the waters with an ad on Ebay and Craig's List. The highest offer I got so far is $10K. I haven't accepted it......yet. This is a 2006 with NAV and 93K miles and advertised as having a new battery with warranty.

I'd take the $10K. I traded in my 06 with 87K with the ailing battery and received $9.8K and was very pleased. Now I drive a CR-V, no more 42mpg, but no more fear of merging neither...

I have mixed feelings. The car performs as well as it ever did and I get good milage, plus I have a new battery with a 3 yr. 36K mile warranty. I would let it go for $12K, but I am not sure at $10K.

Do you mean the 2010 upgrade?
A very good synopsis of what a lot of us are experiencing. My view is the software upgrade highlights the serious deficiencies of the Civic hybrid. It has a very small gas engine requiring constant and consistent help from the electric motor but the combination of a small gas engine and small hybrid battery pack are not robust enough to cover all types of driving conditions, such as using AC in start stop driving in hot weather. Furthermore, some of these IMA batteries are deteriorating and are making the Civic even less predictable and safe. And the software upgrade has reduced the consistency and amount of electric power which has made the acceleration more unpredictable and unsafe.
Even before the battery problems and the software upgrade, I had frequent discharges and no electric assistance when I was driving in hot weather with the AC running in start and stop traffic. It didn't bother me at the time but I now think it is unacceptable and unsafe. I mean, Honda should have said the car is only fit for driving in temperate weather conditions and not in start and stop traffic.

I think you have described the crux of the problem. However, I must say I found the system acceptable with good milage and adequate acceleration in hot Florida until the battery began to deteriorate. I'm not sure that it would be the same in a hot, hilly location.

The system may be acceptable in most driving conditions with a fully working IMA battery but I'm not sure it is adequate for hot and hilly locations. But the IMA batteries are deteriorating in many of our cars after 2-4 yrs of driving and adversely affecting performance in less challenging driving conditions. This mechanic that fixes IMA battery claims that the IMA batteries get fried in hot weather driving http://www.hybrid-battery-repair.com/ Shouldn't Honda have figured this out when it was testing its system?

Obviously, Honda didn't do something right. Toyota does not have these type of problems to this extent.

...but I am not sure at $10K
Are you nuts? I would not think twice if I found someone willing to give me that money for the car, but hey if you think you can find someone who'll give you $12k then good luck. Maybe I should look into selling my car on eBay/CL next time.
