Terrible mileage lately    (Score: 1, Normal) 02-13-2012 14:16

My current trip A reads 33.x MPG :(

It seems the Insight battery can't figure out what's going on. Sometimes it thinks its low so it force charges the crap out of it, charges the battery to full but will still read ~60% until it does a recal, until then I get no assist cause it thinks its low and no charge because its actually full. It does this every few miles so I have to pretty much go WOT to get anywhere. I have actually seen the battery charge at 0% o.O, no bars in the box. It's been slowly getting worse over the last few months.

Until I actually take it to Honda, anyone seen anything like this before? Honda told me when I was there inquiring last week that there is a firmware update but he had no details.

How old is your car? Could it just be that battery is going dead?

To me that would explain it...

Please post back, let us know how this plays out.

Best of luck.

if you live in california your battery is warrantied up to 150k miles..


also if you live in California you can sue honda for false EPA advertisement and win 10k dollar;)

Are you sure it isn't simply the effect of very cold weather?
- Where do you live?
- Do you have snow? lots of water on the road?
- What is the outside temperature like recently?
- How long do you usually drive it? Where? (around town?, on open roads?)

33.x mpg is nothing extraordinary for very cold weather (bellow 5ºC) and urban use with not so long trips (less than 20min).

Either way, just asking; if the battery is really bad the only thing you can do is ask Honda (your battery is still under warranty). You'd be the first I've heard with a faulty battery on an Insight, but it sure doesn't mean you are the first unlucky guy.

Chicago and its def cold weather up here.

Temps are around 20-40F. Drive is around 35 miles one way to work, all highway, maybe 10-15 complete stops the whole distance. I used to average low 50 MPGs being nice and high 40s with road rage. The mileage drop is because I have to speed up to 60mph with no assist, then cruise at 60 while it force charges and finally come to a stop w/o regenerating.

It's kind of annoying because when I used to deliver pizza before I could average 40MPG IIRC City driving and currently getting mid-low 30s highway.

I seemed to remember some sort of 'IMA Reset' procedure being mentioned in a thread here at some point, so i went googling and found some pretty scary stories about failing batteries on 8th gen civic hybrids. The stories sound similar to what you've experienced though a lot of people blamed hot weather.

unfortunately the many stories seem to give credence to some of the fears and concerns I myself had about long-term issues with hybrids and specifically the performance of the battery packs. It will be interesting to see what happens over the long term with some of these BEVs that are being developed.

a lot of people are comforted by the long term warranty on the battery packs in the cars, but then these people who have had problems with their civics are saying that Honda dealers have addressed the problems through a "low cost" approach. Instead of replacing the battery pack, HCH owners out there are saying that the dealers have supposedly been reflashing the system controller so that it puts less stress on the battery packs, thereby delaying the complete death of the pack but otherwise destroying the performance and efficiency of the vehicle. That SUCKS, if true, as the HCH and Insight barely possess any performance in the first place.

Anybody know if these battery issues are specific to HCH and insight or if even high mileage prius suffers from similar issues.

Well, 20 is quite cold... Typically below 0C (32F) battery performance decreases quite a bit, your tires get really under-pressure (unless you readjust it), aero drag increases considerably, and if there is poor weather around friction gets you yet another hit. Remember your car charges most of the battery while on drive (and not really when braking), and it plays with ultra low-friction (from tires, aero, drivetrain, etc.) to do it. When friction isn't that low there is simply not much left to efficiently charge the battery, and in cold weather it's charging/discharging performance decreases making things even worst.

If you drive it for long distances you wouldn't see so much of a change, but I don't think 33+mpg is crazy on 35miles drives with 10 - 15 full stops and re-accelerations to 60mph with an outside temperature of less than 32F. It is for sure on the lower end of what I would expect, but to me at least not necessarily a symptom of major battery problems. From my experience on very cold weather hybrids get larger FE drop than normal cars. That together with the fact that people driving them monitor their mileage much closer may make it a big deal.

As I said though, if you are really concerned about it take your car to a Honda dealer. If they are honest they have the means to check the battery health in no time and let you know. Myself I wouldn't be surprised if by spring your mileage had recovered to where it was.

PS: Don't know if you guys have been following it, but there are actually quite a few reports from GM dealers saying they are finding it very hard to sell Volts in winder because the battery performance lost so much the car EV range doesn't make it for the usual test drive and consumers are disappointed. Fact is EV's only have the battery, so they have to feel even more the winter drop.

I don't have any links to support it, but I really wouldn't be surprised (based on reading reports here and there) if the failure rate of Honda hybrid batteries was bellow that of let's say V6 AT transmissions for example.

The thing is people make a huge deal out of any trouble anyone finds with a hybrid, and take things out of proportion. Honda has already sold nearly a million of those, and the battery problems remain very limited. When you build one million cars of any kind you know you will get some troubles with some of them, that doesn't mean any prospective buyer should be afraid of it, and that's why warranties are made for.

I think Jeff has a good point. I am not a owner of HCH or Hybrid of any kind. but my guess it that all battery performance degrade over time... and, to what degree the degradation of battery performance become a warranty concern (to Honda)? it could be there is a "gap" between consumer's (or public) expectation and Honda's guideline (or pocketbook).

Jeff.

I had the reflash with no problems and no change in mileage.

What I have noticed is that the battery display can be weird. Sometimes it will stay low at three bars and then within three miles it will jump to full. So, if this happens, when the charge is low the auto stop won't work and the assist won't come on.

The trick at that time is to alter your driving habits a bit to give the car a chance to "charge" the battery... Once you're into the four bar range then assist and auto stop will come on.

Other things to watch for... with a heavy electric load at night... fan at full blast, defroster on (AC), lights, stereo, the auto stop may not kick in because the engine needs to keep running to keep the load running.

In hot weather too, if the AC is on and the fan in at full blast auto stop may not kick in.

With rain, forget it, your mileage will drop by 10% for sure. Tonight coming back on the freeway it was raining hard, so my mileage dropped to 35mpg from the usual 39... I've seen worse in heavier rain.

In cold weather your mileage will also drop.

If you change the tires to less efficient ones your mileage will drop by 10% ( this affects all cars, btw, I spoke with a Prius driver the other day... she's running Michelin X tires like me and her mileage dropped by 20%!!)

So, hybrids are running at the very edge of current efficiency technologies so they are very susceptible to the kind of external inputs (rain, cold, AC) that don't affect "normal" cars: dropping from 29 to 26 mpg may not be noticeable, but going from 44 to 35 is.

But, hey, on a bad day I still get 34mpg at 80mph.... that ain't bad.

Issue here is that many drivers are clueless and do not understand that driving a hybrid for mileage requires some learning and technique.

jeez...

Oh.. another thing... we are very proactive. The car goes into the dealer for maintenance per the book and he always checks the battery for us. So, we don't wait for things to get bad...

The weather has a big impact on the battery charge... I can see it even here in SoCal.

Question for you.. why are you waiting so long to take the car to the dealer? We take our regularly for maintenance and the battery is checked. Any issues that we have seen are always checked out.

It's no surprise to me that if people don't have their cars checked when things don't run the way they expect it leads to confusion and anger.

Have the damn car checked... ASAP.

I should follow up huh, lol. Found the cause, even in 70 degree weather if you were going ~25 mph and up a hill it'd do a neg recalc every single time. If you sped up to over 30 before hand on the exact same hill you'd be fine. I could repeat this 100% of the time. It would just drop the battery to 40% and kill assist and force charge until the battery was full. Then the car would show a low battery but be full so you'd have almost no assist or charge until finally 3 miles later it would figure it out by doing a real recalc. Solution was to buy a 2012 Civic lol.

TonyE: "Jeff. I had the reflash with no problems and no change in mileage. What I have noticed is that the battery display can be weird. Sometimes it will stay low at three bars and then within three miles it will jump to full. So, if this happens, when the charge is low the auto stop won't work and the assist won't come on. The trick at that time is to alter your driving habits a bit to give the car a chance to "charge" the battery... Once you're into the four bar range then assist and auto stop will come on. [...]" [Emph. added]

Tastycakes: "[...] Found the cause, even in 70 degree weather if you were going ~25 mph and up a hill it'd do a neg recalc every single time. If you sped up to over 30 before hand on the exact same hill you'd be fine. I could repeat this 100% of the time. [...]"

I've tried every trick known to man in my Hybrid, and if I turn off A/C, feather-throttle everything, do not EVER go wide open throttle, and gradually come up to speed on the highway, I can get about 35-36 MPG one way on my commute.

If I drive "normally", or if I have no choice but to punch it like on a merge, I am between 30-32 MPG all day, every day. Like I mentioned before, I bet I could have gotten damn near 30 in my Si if I paid half the attention I have to in this hybrid. Of course, I never did because I drove that Si like I was being paid to red line it.

I know one person who actually drives a Prius, and he claims to get between 43-48 MPG without any paying attention or techniques on maximizing MPG. He "just drives it". That is what would expect out of the Honda, but as Tony and Tasty, and Andrew have made clear is...you have to work at achieving these things. It actually stresses me out when I try and pay attention to these things, and it does get quite irritating.

Maybe you are trying too hard. I once tried to drive according with input with my fuel economy meter thing (long=save fuel, short=no save fuel) and the MPG I got was not worth it, acceleration was too slow and I was not enjoying it and either was holding people behind up or they cut in front of me . But eventually I figure out the sweet spot.. get up to speed quickly below certain RPM, and then coast and just barely touch the throttle for crusiing when on open road, then coast to stop when there are not people behind me... or in a jam I just coast a bit more and such and I am getting pretty good mpg for the driving I am doing. Though I am not driving a hybrid. I figure I would see a much nicer mpg if I were.

Lately though my MPG is dropping by a lot but that has to do with the road I am using .

I'm convinced low-rolling-resistance tires have quite an impact on mild hybrids in particular. I bring it up because I think you've said you car has regular all-seasons. Just a thought.

First off... it's all in your tires. LRR? Great. Not LRR? Bad.

Second, it's all in your drive. Short, hills? Bad. Long, flat? Great.

Third, it's all in your left foot. Heavy? Bad. Light? Good.

I know several Prius owners.. They all drive it like a Prius. Perhaps your acquaintance drives his/her Prius with no regard, but that may be because his/her normal habit are those of a Camry/Corolla LE driver.

If you come from an Si to an HCH you need to adjust your driving technique more than if you go from a Camry LE to a Prius.

To give you an idea on driving conditions and mileage.. in my old commute, I would get 40mpg+= even at 80mph. Long stretches on cruise control. The battery would fully charge.

In my current, ultra short commute, I'm lucky to get 30mpg in the HCH and the battery never fully charges.

BTW- I get 16mpg in the '12 Si in my "short commute".. and I do this short shifting, going 2-4-6, never punching it, and overall driving it _slower_ than the HCH... So there.

Been through it all Tony, and trust me, I know how to drive a car lightly versus heavy. I know it is naturally assumed I am stomping my feet through the floor like a caveman at every available opportunity, but I am not.

That Si sounds like a pretty bad choice for you.

Not really... I mean, when your round trip commute is just over 6 miles everyday, fuel mileage is almost a non issue.

I mean, in my previous commute I was getting around 40mpg but I was filling up the tank with 9 gallons every other day... so that was like (4 bucks per gallon then) about 90 bucks a week.

Now take the Si, figure that if I drove it " in normal mode" I'd get 13 mpg... which means the 12 gallon tank would last me... 26 days.... or about five weeks. So that's about $10.39 a week ($4.50 for premium).

Or if I drive it for mileage, then I get 17 mpg... so my weekly cost is about 8 bucks week.

Or if I drove it like a banshee, then I'd get 10 mpg, so my weekly cost would be about $13.5 a week (plus tickets).

Of course, whether I drive it like an old lady or an 18 year old kid on hormones likely makes no difference in the time it takes me to drive since most of the time is spent at red lights (tickets, however would delay me...).

So, I entertain myself by driving it as efficiently as I can. And every so often I'll jump on the freeway on ramp right behind work and haul ass on the on ramp -but you gotta watch out, I once got a radar ticket right there in the 03 RSX-S... which, btw, according to the CHP did exactly 84 mph at redline in 3rd gear ):-P

Heck, I could likely afford to drive a Peterbuilt Semi to work nowadays... ;-)

Your HCH... again... have you taken it to the dealer, have you talked to AHM about it... I think something is really wrong with your car. IMHO, AHM does care about the HCH, we had an issue with the instrument panel once and they really supported us ( it was a short in the rear fuel sensor due to body work done at the dealership... but it took three weeks to figure it out).
