#478 of 1535 Still Going Strong with IMA Light On
Aug 13, 2010 (10:49 am)
2004 Civic Hybrid: It's been about a month since both my IMA light and check engine light went on and the dealer quoted me $2700 for a rebuilt battery. Temps have remained in the upper 90s during the day (Kentucky). Battery still charging and uncharging as normal - no problems. Car is running strong as normal and has 155K miles on it. Battery Warranty was gone a long time ago. Anyway I believe in the Civics as a good solid car and have bought 3 of my sons Civics - just not hybrids. My fiance has owned 3 Honda Insights including a 2010. I believe I will probably not be buying another hybrid any time in the future but I have not ruled out a Honda. Although the VW Jetta TDI was a nice test ride. I have noticed over the years that many regular civics and corollas are getting about same mileage as my hybrid so not seeing any big difference on gas saving. YES I do have a lead foot and I'm not about to change that anytime soon. I guess I will wait till she dies and then use one of the 2 online places I found to send the hybrid battery into for repair and let you all know how that goes.

Honda's warranty is 8 years/80,000 miles outside of CA. I'm uncertain about the warranty in NY and all the other CARB states, but in CA it is 10 years/150,000 miles. This is the warranty on the battery. If they replace the battery, the original warranty is still in effect. This means that if you bought the car in 2006, the warranty would run out in 2014 no matter if the battery had been replaced in 2008 or 2012 - or both.
When I said "patch", it was a computer term for releasing a slightly changed version of a program that completely replaces the original one. It was not meant to mean that it was a patch-job or in any way shoddy. It is probably a small change or tweak to the thresholds in the code.
As far as I know, future software updates will be free to you even out of warranty.

> To stand back and quote lb./hp. (power to weight) ratios and comparing them to a slew of other vehicles does not tell the whole story. This is NOT the "end all" of vehicle dynamics where performance is concerned.
It is when you are talking about acceleration. All we were talking about was the safety of the car when the driver was suddenly presented with a no-assist condition. Underway, you won't even realize you didn't have assist. It is only when you are trying to accelerate (such as in the left turn we discussed). In that case power to weight is the only factor because gear ratios and tire diameters are approximately equal. The car with the best power-weight ratio will make the turn fastest.
I'm only talking about the safety aspect. Not the enjoyment aspect.
> It seems your goal while driving would be maximum fuel economy
That is the reason that I bought and drive the car that I do. Maximum fuel economy without inconvenience. Wayne Gerdes personally taught me how to hypermile. I won't drive like that even though I can get 120 mpg. Why would you buy a Hybrid if maximum fuel economy isn't your goal?
> and while achieving that (due to your adherence to all traffic laws, especially speed limits),
Are you chiding me or making fun of me because I choose not to break the law? Carried to the extreme, that attitude implies "Go ahead son, the shopkeeper isn't looking, just take one piece of candy. He won't miss it."
> you have the time to thoughtfully plan all of your moves a half mile ahead.
Not meant as a criticism, but on the highway, you are supposed to be looking 20-30 seconds ahead, so yes, at highway speeds you should be observing what is going on half a mile ahead. You should not be tailgating and staring at the bumper of the person in front of you. You should maintain a proper following distance and watch what is going on up ahead because you'll be in it shortly.
Whether you choose to do so or not is up to you. I'm less worried about someone rear-ending me on the highway because they were tailgating me (smaller closing speed-smaller impact) than some idiot cutting me off by turning left as I'm bearing down on him.
>"well, since you bought the car for economy you might as well Sl.....oooow down and thou shall have no safety issues because according to the power to weight chart your car is "in theory" faster that many"???
If you Sl....oooow down, your battery won't be empty and you won't have a no-assist condition. You'll also get great gas mileage, polute less, and it will only cost you a few minutes out of your day. And with a full battery, the car will be "in fact" MUCH faster than many.
> I just know you will have one of your calm point-by-point dissection sessions of my rather emotional reply.
Yes, why don't you try a less emotional reply next time and discuss things rationally.

That's a pretty good price. Usually it's about $3000. Most likely, you have a P1449 error, as a P1433 or P1447 don't usually light the CEL. You are probably losing about 5mpg due to the battery's inability to accept a charge (or at least all the charge that is fed to it). Keep an eye on the battery light/alternator light. As long as it stays off, it is safe to drive the car. If it lights up, you must fix the battery. If it lights up while you are away from home, do this: disconnect your 12V battery for 20 seconds and then reconnect it and drive straight home. The light will be back on soon, and when it is on, the 12V battery does not get charged.
Your maximum range is about 20 miles with the light on.
The 2003-2005 cars are not as affected by heat as the 2006-2010 are because the AC compressor is belt driven and does not present a drain on the battery.
The software updates mentioned at length here do not apply to your car.

#483 of 1535 IMA/Battery problems after software patch
Aug 13, 2010 (1:22 pm)
Well, I didn't have a choice about the software update. My IMA light came on. I took to the dealer to investigate. They had it for six hours. Then I found out about the software change. My 2006 hybrid with 107k miles has been under performing every since. Auto-stop doesn't engage at a stop with full charge. No power assist trying to merge onto the freeway or to accelerate out of the carpool lane. The software is masking the battery failure to hold charges. Definetly unsafe. Also, do not believe your mpg reading. I went 10 miles at 70-75 mph with the ac on and it said I as averaging 45.7 mpg!!! Honda is trying to avoid replacing defective batteries under warranty by masking the problem wig a software change that seems to be recalibrating itself based on how much charge load the battery has at any given time. There no way the battery holds the same charge as before the software change!! We'regoing to be left with defective batteries that we have to replace on our dime. That's not fair business practice.

Whether you ever buy another Honda is up to you. I shopped the HCH around to various dealers. The best price by far came from Honda - and they are well aware of this issue. I had no interest nor time to fight Honda for a new battery, class action suit, IHSTA complaints, etc. Everyone's situation is different.
Good luck in your fight. I am enjoying my CR-V in this 95 degree CO weather!

I have had a few times this year with mt 2007 HCH2 with 45000 miles on it that the heat seemed to push down the battery power during hot stop and go driving. I am not ready for an update. I also am not yet a Honda hater. So for I have only found this forum with a hundred or so people mad, bad cars and ready for a lawsuit. That is out of the hundred of thousands of these cars sold. My thought is maybe this is not as wide spread as some think it is. I feel any car that is messed should be taken care of by Honda but does it need a class action for an answer. I done see any ambulance chasing lawyers contacting anyone. This car is the most trouble free car I have ever had. I see people praising VWs. Had a couple. Lots of repair bills Honda was just rated in the top five makes people planned on buying. not VW. If you are having problems maybe one should look past the TDI you might end up with another headache.
#487 of 1535 450 Miles on June/July Software Update
Aug 14, 2010 (9:27 am)
Environment: Las Vegas Summer - every day well over 100 Deg F. with stop and go driving
Since the recent software upgrade, mileage and performance continue to significantly improve. Mileage up from 38.0 pre-update to today over 43.0. Driving is 90% Las Vegas city with a lot of stop and go. I occasionally run-out of assist in heavy stop and go and usually in temperatures over 105 F. However, I have found that some assist is usually available even with 2 bars but you have to really push on the gas to get it.
It seems that under really adverse conditions - very hot over 100-105 degrees F with stop and go driving - that any assist is non-linear relative to gas pedal movement. In other words, you really have to push on the pedal to see the assist (whereas, with more bars, assist is available with small pedal movements).
If my 2008 Civic Hybrid with 23000 miles continues to get over 40 MPH in the Las Vegas summer, I find that very acceptable. The upgrade DEFINITELY SIGNIFICANTLY improved my fuel economy and overall performance,
In the cooler weather coming in September, it can only get better. I too was VW'd and it was the worst nightmare I ever had with any car. Electrical, A/C, valve stem seals/high oil consumption, et al. You had to know where the electric fuel pump relay was under the dash - so when it didn't start - you could pull out the relay and tap it on the ground. This was on a NEW VW sold to me as a premium vehicle.
I too find the CONCEPT of the TDI attractive - BUT after my VW nightmare and current assessments of reliability still very low by Consumers and almost all others - and still showing electrical problems, I'd be VERY cautious about VW's. Also, call VW and ask them if they machine brake rotors - they will tell you like BMW - NO they replace them. Makes for big bills for brake jobs - after the 3 year free maintenance (and during that period) very little maintenance is needed beyond oil changes.
