#14 of 33 Honda Accord Hybrid 2005 - Battery Replacement Story
Feb 19, 2013 (1:01 pm)
Just a week shy of the 8th year anniversary (and 1 week from the end of the warranty), I had the IMA & check engine lights appear (Diagnosis code through OBD-II of POA7F).
I took it to the dealership where the diagnosis was failure of the IMA battery, which was replaced under warranty. After doing some more reading about Honda's Civic Hybrids, I decided to ask if they were using a remanufactured battery, and turns out they are. How the batteries are remanufactured could not be satisfactorily answered. I asked if they replace all battery cells or just the failed cell, and I could not get an answer from the dealership or Honda's Customer Service. It seems there is no other option, as new batteries do not exist.
So I pick up the new car and it drives like a Prius and is getting the milage of a minivan (28 mpg after 2 hrs of highway driving in no traffic with average speed of 45 mph). In particular, the electric motor no longer activates at low speeds (< 25mph), and does not help at low speeds, where the performance advantage of the electric motor is greatest (ie high torque at low RPM). I called the dealership to see if any software was loaded, and it was. I'm thinking that this software patch could be similar to what Civic Hybrid owners were complaining about? Where the software patch reduces the battery usage to preserve battery life, but at the expense of performance and acceleration. If anyone else has noticed this on their HAH please post, as I would like to compare experiences and resolutions. Thanks, Scott

You're kidding... MY IMA light just came on this week, and now the light that looks like the engine block. I haven't gotten it to the dealer yet --- I am not fond of the local dealer service departments. They were not remotely helpful with the ANC problem. I hope others will write about their experience with the IMA light, etc. This is the best service manual going!

Just came home from the dealer... they said they are getting me a deal: I'll only pay 20% of the cost of the hybrid battery, or $520. Somehow I think when I pick it up tomorrow, there'll be another couple of hundred tacked on. My car has about 115,000 miles on it. If anyone know how to get more off, please let me know!
#17 of 33 2005 HAH Battery
Feb 24, 2013 (8:33 am)
Glad to see this recent activity. My 2005 Accord Hybrid has 120,000 miles and the check engine and IMA light have gone on and off intermittently for the past 10,000 miles or so. This more repeatedly happens during the colder winter months here in northern MS. The car has been absolutely great and I've owned it for the past six years without any problems other than the noise cancellation system which the dealer replaced for me with no cost shortly after I bought the car. I regularly get around 25 MPG in the city and have gotten (only once) 42 MPG on the highway. That was a fluke, as I usually hover about 34-36MPG on the highway. I will be contacting the American Honda Customer service folks tomorrow to begin the process of IMA battery replacement. I will post again once I have further action. Thanks to all who are writing here as I live in a small town in northern Mississippi and the nearest Honda dealer is more than an hour away. It's good to read other people's experiences with their Accord Hybrids.

I too am INCREDIBLY grateful for this forum!!! Without it I would have undoubtedly paid thousands of dollars. The Honda dealers would not acknowledge the ACN problem even when I showed them the service sheet on it. Finally they disconnected it literally to get rid of me. Having it disconnected made it bearable, although obviously something isn't working right anymore if it's disabled. (I have no idea what) I still instantly know when the car is at 1500 RPMs; that's when the ANC problem was obvious. Why Honda hasn't done a recall is beyond me. Maybe enough of us haven't complained? If not, we certainly should.
You can take your car to Auto Zone or someplace like that and tell them that the IMA light has gone on; they have a tester and can look it up. That's how my battery problem started, too. Saves you that trip to your dealer, because they will probably have to order the battery and won't have it for a day or 2. Good luck!
#20 of 33 IMA Light Check Engine Light and no sign of the Hybrid battery being charge
Mar 19, 2013 (1:11 pm)
I own a 2005 Honda Accord Hybrid, I took it to the dealership and got a diagnosis done on it and was told that I need to replace the IMA Battery and possibly the IMA motor. Given how expensive it would be to replace those two parts at the dealer, I decided that I would purchased the parts as recommended and take it to a shop and have them replace it for me. So I did and the problem still exist IMA battery still not charging and the IMA light and check engine light is still on. I'm in need for some great advice before I decide to put anymore money in to the car. FYI This one shop in New York told me I might have some wiring problem given the fact that the car was involved in an accident.

I got a similar deal here in Los Angeles area. I have about 120K miles on my HAH, and over the past 3 months, the check engine light/IMA light come on intermittently. I was concerned that the light kept going away and the dealer wouldn't be able to diagnose, but when I called my local dealer, they said the code would be saved in the computer system and they could still diagnose the problem. I've called the dealer in the past and was told that a new battery runs about $3K, but the last time I called, the rep was very helpful and mentioned to take the car in and that he would contact American Honda on my behalf to see if they could provide some goodwill towards repairs costs. I was pleased to hear that they would charge about $590 I think, including the labor. At this point, I definitely don't want a new car payment, so I'm willing to fork over some costs for a battery. The dealer did mention that it's a remanufactured battery pack (they don't make them new anymore) and there's a 12 month/1 year warranty on it. I'm just concerned that a year is not very long. I'm hoping it will last another 8 years! I've read elsewhere online that the car will still run with a bad battery, the MPG will just get worse. I guess I'll take a chance if it dies again, I'll just keep driving it until I can't drive it anymore :/

Just wondering, since you got your battery replaced back in 2010, have you had any further problems? My HAH is at the dealer, and American Honda is providing goodwill also towards the repairs, but the service tech told me that the battery pack is remanufactured and has a 12K / 1 year warranty. I'm wondering if I should expect several more years out of a replacement remfg'd battery.
#23 of 33 Replacing Replacement Hybrid Battery....
Jun 27, 2013 (5:52 pm)
Sigh. My 2005 Accord had its IMA batteries replaced under warranty at roughly 60,000 miles. For the past six months, the replacement IMA batteries have been malfunctioning. They updated the software, and the replacement battery continues to drain daily. Soooooooo, today, 2005 Honda Accord Hybrid has 118,000. I "saw" a warranty for 10yr/150,000 battery warranty for the replacements. However, the dealership is certain there is no such warranty. I'm frustrated and disappointed that I've replaced these damned batteries TWICE in eight years. Does anyone have "warranty" intelligence about the replacement batteries?? What would you do if you were me? Mileage is hovering around 24 mpg and batteries are charging themselves from my primary battery. Not impressed, Honda.
