Honda Insight Hybrid Battery Pack Questions

1235

Comments

  • I also have 2000 Insight and had almost exactly same scenario. My light came on earlier this year but I had less than 150K miles so it was covered under the 2008 warranty extension for manual xmissions to 10/150K (bulletin is "monitor and motor control module" Honda Service Bulletin 06-057 dated Feb 5, 2008). I was also told that the "new" battery is reconditioned and any battery failures, even during the warranty period would not be covered.
  • Had the battery replaced. Contrary to the info you received my battery has a new 150,000 mile warranty.The new battery is not working properly so back to Honda West.
  • I'd find a new dealer. Call Honda. They will remedy the situation. I call them to see if I could get a mechanic outside the agency but they wouldn't allow. They stated the any new installation would have a 150,000 mile warranty.When I called Honda West they agreed with the installation and did so free of charge. Be tough.
  • I have a 2001 Honda Insight and the IMA light on the dash has been coming on!

    How do you recondition or rebalance the 144 volt batteries?
  • Honda warranties these batteries for 10 years/150,000 miles. If you're within these limits, I'd check with your local dealer.
  • See your dealer. Warranty should cover . If not call Honda International. My 2002 had CMA light come on 90,000 miles. I called Honda. I was directed to the nearest dealer and a new battery was installed, no charge. Got free rental car while in shop.

    I have a 2000 insight and last week the IMA light came on. Took it to the dealer, and they said it was a P1447 code - battery module definitely needed to be replaced ($3474) and once they took that out they would see if I would needed anything else replaced (possibly another $3575). I have driven about 150 miles since then, and everything seems to be working perfectly: my mileage is the same, autostop is working, the battery is charging as usual, assist is kicking in as usual....

    So does this mean everything is actually o.k.? Was the test wrong, or is my battery starting to deteriorate but not enough to effect performance?

    Any help would be greatly appreciated! Thanks!

    Your battery has already deteriorated and has gone below the threshold required to light the light. You aren't seeing a change in economy because you are already suffering from it and probably have been for a year or more.

    Your concerns are:

    1. you cannot pass emtissons in most states. If you are in a state that does not require emissions, you can put the IMA system into limp-in mode and drive it as a non-hybrid.

    2. The P1447 indicates that the battery is wildly out of balance and some cells are extremely weak. Over time, these cells will bear the brunt of the assist work and will be made weaker. Eventually they will start to fail and will cause the car to shut down the IMA system to prevent overheating (read:fire) and will shut down the DC-DC converter (aka the alternator). Then you will be stranded.

    If you purchase a pack from the dealer, they can no longer require you to replace the BCM and MCM (at a price of $1800) which should limit the cost to about $3000.

    Of course, you could have it repaired instead. You should look on Insightcentral for information about this error and what you should expect.

    Any battery replaced under warranty does not have it's own warranty. It is covered under the car's 150,000 mile warranty. It doesn't matter how many times it is replaced. As long as the car is within the 10/150,000, you are covered.

    If you PURCHASE a replacement battery, it comes with it's own 3/36,000 warranty that is independent of the age or mileage of the car.
  • I have a 2002 Insight. CMA light came on, drove it awhile, during this time I got the same mileage as before the light came on. After a short time the car stopped, had it towed to Honda West, Las Vegas. It was confirmed that your code along with another was on and that the battery assembly and a control unit needed replacing.
    Honda replaced the battery assembly and control unit at no cost to me. I believe the bill was in excess of $8,000.00 (paid by Honda)

    With the new battery assembly in my initial mileage was 37 MPG, scary, that is the same mileage I obtained when using only gas, Then, for some reason, the mileage started to increase, now I'm up to 48.8 and feeling better.

    When this situation came about I called Honda regarding the codes, the warranty and replacement. They responded that I should find a dealer of my choice. When doing this I looked for a dealer that would offer a free rental. That ended up being Honda West.

    This experience has resulted in the best treatment I've had with a dealer and Company (Honda).

    Thanks! My mileage did seem to drop about 2 years ago, so what you're saying makes sense. So will I have any warning before the eventual stranding? Will my mileage go down drastically or the battery stop recharging -- or could I get in the car tomorrow and it wouldn't start?

  • On my 2002 Insight since the battery replacement the mileage has decreased to 42 mpg. What I'm afraid what has happened is that when the dealer replaced the battery a new battery pack was installed ( the newer technology) resulting in the lower mileage recorded on more recent models. I was unaware that this was being done, in fact somewhere in the message board a comment was made alerting users to be aware not to let this happen. please comment on this.

    >With the new battery assembly in my initial mileage was 37 MPG, scary, that is the same mileage I obtained when using only gas,

    That's normal. The IMA system doesn't increase gas mileage, it make the efficient but anemic engine feel like a normal engine while still retaining it's gas sipping qualities.

    If the battery light comes on (the "alternator" light), get under the hood and unplug the 12V battery for 30 seconds and then reconnect it and go straight home. This will reset the system and you should have enough time to get home before the error comes back.

    This will only work once or twice so don't think you can continue to drive the car.

    The latest software (A01/070) is attempting to lengthen the life of the battery. It does this by being more liberal with assist when the battery is more than half full and much more aggressive with regen (killing your mileage) when less than half full. In addition, it will periodically perform a balancing charge by deciding to fill the battery completely, even when trying to climb a hill.

    Once the car is out of warranty, you can simply replace the BCM and MCM with an older set and restore the original behavior.
  • What do you mean OUT OF WARRANTY? With this new battery I get an additional 150,000 miles. Don't think I'll be around that long.
  • Ogre_GEVOgre_GEV Posts: 263
    Your new battery has no warranty at all. Your CAR has a 150,000 mile warranty. The battery will be replaced as often as necessary until the CAR's warranty is up.

    If you had purchased the battery, it would come with it's own 3 year 36,000 mile warranty.
  • What is limp-in mode?
  • Ogre_GEVOgre_GEV Posts: 263
    Limp-in mode is a term used in the automotive industry to describe a mode where a computer will, knowing that it has severe problems, ignore its' sensors and use a predefined set of default settings to allow the car to "limp-in" to a repair facility. In this case, it will ignore the fact that the entire BCM (the battery charge controlling computer) is MISSING and will activate the DC-DC converter to keep the car running.
