Probably because your warranty was extended from 80,000 miles to 84,000 miles and you were still covered.

Your 144V battery will start the car unless:
It is depleted
It is very cold outside
Your IMA system is malfunctioning
Please don't go to a dealer and waste your money paying their rates. Any competent mechanic can fix your car. Also, please either pay a mechanic to read your codes or go to an Autozone and read them yourself. Post your codes here and I'll tell you what is wrong with your car.

When your battery light came on, you started running on the 12V battery alone, so it isn't surprising that you barely made it to the dealer.
The dealer has likely "upgraded" your IMA computer (MCM). Now let's see what we can do to increase your mileage.
1. Pump up your tires to 44 PSI
2. Start driving at or below the speed limit. You'll only lose a few minutes a day.
3. Pretend that there is an egg under your foot on top of the gas pedal. Try to drive in such a way that you don't crush the egg.
Try that for a week and see what you get. Let us know.
#307 of 1535 Update on Our 2009 HCH Issues and Other Comments
Mar 30, 2010 (8:09 am)
To review: IMA battery failed at 4000 miles and again at 20000. Honda replaced battery each time without any argument.
My wife spoke with the sales manager at the dealership about not trusting the car to work properly. He went to bat for us and convinced Honda to just take the car back (it was leased). We swapped it for a 2010 Civic EX-L, just writing a new lease with the same payments. Doesn't happen often, but if you have a customer-service oriented dealership, then you can get lucky. So, it was a nice experiment, but it just didn't work out.
But there have been many other issues raised in this thread and I wanted to post my comments about them.
Old IMA Battery Failure
The batteries seem to fail somewhere between 80,000 and 110,000 miles. This should not really come as a big surprise. Ever had a cell phone or laptop battery fail? These are rechargeable batteries, and they do not last forever. Yes, they are expensive. Nobody complains when tires or brakes need replacement, or even the timing belt, which is hundreds of $. If you read my earlier post on Hybrid economics, you can see that you probably did save more money from better mileage than the cost of the battery replacement, and you used less gas in the process. You are still ahead, just not as much as you would like. The fact that the battery failed after many years of use is not something that you can really blame on Honda.
New Battery Failures and the "Update"
This does seem to be a problem, but it does not seem to affect every vehicle. Honda told our dealership that they thought they had fixed the problem (I assume they mean the famous "update"). Some people are having problems with the update, but not everyone. I can tell you from my years of troubleshooting complex scientific instruments that this kind of small, seemingly random failure is almost impossible to troubleshoot and fix. (Toyota has a similar problem with their acceleration issue.) I cannot completely fault Honda for this, but they do have some customer service issues to deal with.
Finally, there are two sides to every story and we have not heard from Honda on this forum. That's disappointing. There are also suggestions in this thread that the update is problematic for certain types of driving. I don't know enough about the specifics, but I can see that the screaming is not going to help. We need to find a more effective way of dealing with the issue.
Good luck to all.

Thanks Ogre (feel like you're famous after reading all these posts).
1. I will pump up the tires although 44 sounds high to me (DC is notorious for potholes and I don't want to pump them to a dangerous level).
2. Can't help but drive at or below the speed limit in this city, so that's an easy one.
3. I do try to "imagine the egg" thing but the streets are so stop and start, it is hard to find the sweet spot to get through an intersection without more than 3 bars of assist.
Since my post two weeks ago, I've gotten the MPGs all the way up to 26.

Burst rating is somewhere north of 200 psi.
44 psi (or whatever it says on the sidewall) is what the tire company says to put in to optimally inflate the tire. The car companies say to put in less to get a softer ride.
#310 of 1535 IMA Battery Charge Fluctuations
Apr 01, 2010 (5:24 pm)
Hey, I have a 2009 HCH that I got at the end of June '09. I've noticed after about 500-700 miles that the IMA battery charge indicator drops suddenly from almost full to almost nothing (7/8 bars to 1/2 bars). This happens while cruising and even during regen, when the battery is being recharged. Is there something wrong, or is this just a form of battery conditioning?
Also, to those looking to get the best mileage out of their hybrid should definitely use cruise control as much as possible. Also, the car has a "sweet spot" efficiency at around 68/69 mph on highways, but the best efficiency I get is between 38 and 50 mph.
I also bought this thing called a z5 (z55555.com) for the car. It claims to enhance the air going to the engine. All I know is that it definitely works. The cruise control used to rev the engine to around 2800-3000 rpms when going up hills on highways, and now only revs to 2300-2500 rpms up the same hills at the same speed.
I also changed the oil to mobil1 synthetic when it came time for the first oil change and inflated the tires to 44psi. I used to get 46 highway, 42/43 city. Now, I get 51-53 highway and 47 city. Most of the gains I saw were due to this z5 thing.
A word of caution, the z5 does not fit completely into the rubber air tube going to the intake, I needed to extend it with a 2" to 2" rubber coupling that I cut in half.

Hi Jack, good luck with the battery, I have an 06, loved it for 2 years, then Honda put software updates and have hated since, am dreading the summer as it does horrible in the heat. The updates lowered the temp when the assist battery helps in order to avoid destroying the battery. Did putting on the z5 void any warranties?
#312 of 1535 Reseting IMA after I ran the battery down
Apr 02, 2010 (6:17 pm)
I accidentally left the door ajar while in church last Sunday. When I came out the battery was dead. I jumped it, drove it home and charged it overnight. However, when starting it sounds like a regular engine with a starter, the IMA and check engine lights are on and the battery charging lights don't function.
I called the dealer who said to just drive it a few miles and it will "reset" itself. I've been driving it a week now and nothing has changed. I don't think the electric motor is working at all. Has anyone else had this problem?

I don't think so, since I didn't modify the actual car. Plus, you can take it out easily enough when you go in for service.
