IMA light and check engine light came on. IMA would not "charge". Had all the codes that the IMA was bad. Honda would not "help" with the replacement of the IMA battery. I risked $350 and bought a "grid charger". It worked. IMA has been working great. Now have 106,000 miles. I definitely would recommend a grid charger.

2006 Honda Insight. IMA battery failed. Honda Motor Corporation will not return my call regarding this problem. The dealer (DW) in Franklin Tn. told me last week $3,500.00 to replace IMA battery with remanufactured battery(3yr/36,000). Now the dealer asks me could I pay $1,000.00 for the repair. I do feel this is reasonable but, HMC knows these batteries are defective as the batteries in the Honsda Civic Hybrid (2006)that are now in a Federal Class Action Lawsuit. I feel Honda should replace the defective battery in my Insight free of cost to the consumers. Whoever heard of a dealer going from a $3500.00 repair, to can you pay $1000.00 ? In my opinion, they just admitted to their guilt. By the way, my wife has driven Honda's faithfully for the past 30yrs.

I purchased this car three months ago and it had a replacement IMA battery in July 2012. at 122,264 miles. It worked perfect until yesterday when the check engine light and the IMA light came on.
I have an appointment to have it checked in a week, but wonder what hints or suggestions people out there might have?
P.S. I have read of a grid charger that could fix or prevent this. Anyone know anything about these?

I replaced the battery with a refurbished battery instead of the Honda battery which costs twice as much. However, the first battery shipped did not operate correctly. I had the supplier send me another battery, which they did promptly. I then had that installed. It works well now. The cost of the paying the dealer to diagnose and install both batteries ran me almost $1,000. My savings in the end was over $1,000 but the hassle and time it took tried my patience. I had to use a dealer because of the voltage on the batteries, the auto repair shops I use did not have the insurance to handle high voltage products.

IMA battery died at 84,XXX miles. Honda refuses warranty because previous owner had wired a voltage monitor into the system. I will never buy another Honda!!!!!
