I think that the HCH uses a bunch of small batteries linked together, so some of them could be failing. However, if the Honda techs say the pack is still within spec, I'm not sure how you prove them wrong. Are you sure that you aren't using the A/C more, or that the traffic patterns haven't changed (causing you to stop more and use the batteries)?
The news article you quoted sounds more like "normal" battery depletion - the lady does too much uphill and not enough downhill to recharge the batteries. Though of course it could be bad batteries in her case as well.

The Insights have has several cases of battery deterioration. I would want to see the voltage readings and specs from Honda. It should still be covered by the 100k mile battery warranty. I have asked before here and gotten a lot of spin. How bad do the batteries have to get before they are contributing more pollution than is allowed under the AT-PZEV regulations? You are kind of at the mercy of the automakers with hybrids more so than ICE only cars. At least until a few independents start working on them.

I just got my 2007 HCH on Saturday. I live in NC and it has been close to 100 here. 93 today. I have been having issues with the IMA not working when I first get in and for the first couple of minutes after that, then it will kick in. It doesn't seem to cause any issue with the battery as the bars for the charge amount remain the same. Anybody else having this problem?? I knew if it was over 100 it could stop working (I read almost the entire owner's manual when I got it home) but it was low 90's here today and it did the same thing.

Replying to own message because I need to make a clarification/correction. The IMA did not fail, the AutoStop did, not exactly the same thing. The owner's manual does say that the AutoStop will not work until the engine is up to temp, so that's why it doesn't work in the first couple of blocks after getting in. However, it will also fail about 5% of the time at stoplights during a trip. Not sure why -- but it doesn't seem to really affect my mpg, which I'm pretty happy with. Would be interested in knowing, tho, if anyone else has this happen to them.

Have exactly the same problem. Was getting consistent 43-45 MPG n daily commute, always watched the charge / discharge cycle, always the same pattern, monitored RPM vs IMA assist on hills, etc.
Then at 48,000 miles this week, BOOM. Mileage drops to 33 MPG, battery holds a charge about 25 to 30% previous capacity, engine revving way up on hills since no assist from IMA< where before in same locations, had assist, etc etc. Dealer says everything checks out OK. My guess is, charging system, Electric motor/generator, and voltage regulation is all OK, and that battery shows proper voltage,,,,BUT, current storage capacity is shot due to losing a batch of cells in the battery. Anyone else weigh in? Thanks.

IMA = 'Integrated Motor Assist', the trade name of Honda's hybrid technology.

I have 2006 HCH. Exact thing happen on a cool rainy day. IMA battery indicated 3 bars when it happened! I have 12K miles on it.
This is can cause a fatal accident!!! esp. if you need to accelerate to make turns or merge!!!
So does putting the car in neutral/park and revving to 3000 RPM really help resolve this problem?
thanks in advance!

battery depletes going uphill

my 2007 hybrid civic's battery drains completely after going uphill for about 2 minutes - then the engine revs and it smells like something is on fire - basically the car won't go anymore - the weather is cool (no high ambient temperature issue) - it happens everytime i go up a hill of any significance - i simply don't understand why honda won't acknowledge there is a problem with these cars - has anyone pursued this to the top of the corporate ladder yet

Have '07 Civic Hybrid: Several days ago noticed no charge and no assist indicated on the gauge with only 2 bars charge showing. Naturally the Auto stop did not work. Manual said the charging system was correcting itself and in a few minutes it would recover. The IMA icon did not appear so system is supposedly OK. Without the assist I have lost power and mpg has fallen. It has been hot here -- hi 90s for several days. When I rev my engin -- still no charge. Made appointment with dealer. Will see him in 2 days from today. From reading messages on this forum, it sounds like the dealer will tell me everything checks out OK -- but it isn't OK ... it isn't working as I bought it... what do I, or can I do. Are my batteries shot at 13,000 miles? Unbelievable. Advice/comments
