Car: 2005 HCH I, CVT, almost 40K miles. I have had no problems at all from it and drive it often (work from home). Average MPG was in the low-mid 50s, then I got some new tires and since it's averaged low-mid 40s. Bought it in '06 from a local (TN) Honda dealer as certified pre-owned and unsure of state it was originally sold in. It has a new 12v battery made in 12/2014. To the best of my knowledge, the ECM has NOT been re-flashed or upgraded by Honda. No other software updates have been done. About a week ago the IMA and Check Engine Lights came on (P1600 and P1433) at the same time and stayed on. When I got home, I thought it a fluke and disconnected the 12v battery for a few minutes. The lights went away; then later came back at the same time. Then the IMA light went off while the CEL stayed on. Then I pulled the IMA fuse for 30 seconds and put it back in; since then no lights have come back on. There has been no degradation of the IMA so far; the Charge/Assist works correctly and there has been no sudden drops or jumps in the IMA battery level per the gauge. While the warning lights are on it still functions properly that I can see. If it weren't for these 2 lights, I'd never know something is wrong. I took it to Honda to see if I still qualified for a warranty replacement. An inept tech told me I did, then didn't. And a replacement IMA pack would "only" cost me $2,500. I mentioned warranty extension SB 12-077, but he didn't seem to know exactly what was going on. I have a call into the service manager who has yet to return it. So I'm screwed. After some quick research on this and other forums, I have come up with several options, in no order of preference. 1. Buy a replacement pack from Honda. The tech told me the pack would have new, unused cells in it, which I corrected him that they don't; they're refurbished packs from other failed Civics. He then told me that "the other guy's" packs are untested with no warranties. 2. Buy one from online, like Bumblebee. It costs a bit less, but still it's a large chunk of change. Plus it has a warranty. 3. Not buy one off ebay or a junkyard, as I don't know how long they've sat there and they have little or no warranty. Plus, they could already have these problems. 4. Visit other local Honda dealers to inquire about my IMA warranty and see if they'll help. I've read posts about owners convincing a dealer to allow the warranty; how did they do it exactly? 5. Call Honda America and explain my case and hope they allow it. Does this ever work? 6. Get a grid charger and attempt to repair it that way. From what I've read, batteries like mine can be recovered in this manner. But I'm not exactly sure what type of GC I need or the features it should have. What is the best one, with the best features, for the best price? If I knew someone local I'd ask to borrow theirs. And if it works, buy my own. This apparently has the bonus of not having to remove the IMA battery pack from the car. Even if this takes a few days, I do have a beater I can drive in the meantime. I've seen sites where the entire pack was removed from the car, the cells removed and unwrapped, and each one charged/discharged a number of times before being rebalanced and reinserted into the pack. Anyone who has had issues like mine, what did you do? And how has it worked out? Thanks for any help given.
