I see in FAQ that HJ is suggesting a new battery is required for a CRV a where stop start is not operating. If the battery is not holding charge then this is sound advice in this case. However stop start on my 2012 Civic doesn't work once winter kicks in as although the battery is otherwise OK my usage of the car is such that the battery seldom reaches full charge in winter and the system is set up only to work with a fully charged battery. Mine is working intermittently at the moment but I am sure come spring it will kick in again. When it first "failed" the dealer sent me a questionnaire about my use of the car and it's clearly a known problem. In my case fitting a new battery would not solve the problem as my use of the car is too infrequent to keep the battery fully charged. Not sure if other manufacturers' systems are similarly picky about when they will work?

It sounds normalish.
Maybe cabin heater demand/engine temperature too low or indeed the battery monitoring has assessed it as too aged or insufficient state of charge. If there's one thing the Japanese have never done very well, it's software and this is the main reason they are no longer the tech giant they once were.

On all stop start cars the system will only work once the engine coolant temperature is up to the normal or standard value.

Also if the battery is not fully charged it will not operate.

It is a good idea but the fuel saved is minimal. They-car companies, would be better spending the time and money in making the car lighter and safer.

There is a long list of conditions for stop start to operate.

I had trouble with my CX-5 in the first year where the battery wasn't being charged sufficiently, eventually the battery got too low to start the car, dealer said the system needed reinitialising its been ok since but i always check the charge volts now by monitoring the plug in volt meter.

I certainly wouldn't rush out to change the battery as they are very expensive for a stop start system.

As for the SS i sometimes find it useful when at traffic lights, but inconvenient when going through a gate entrance for example, at those times i turn the SS off, on the Mazda its called I-stop.

I have a 63 plate Civic 1.6 diesel and on the odd occasion I forget to deactivate the stop-start, I notice it doesn't always stop at lights etc (even if fully warmed up), but a symbol comes up on the screen near the speedo with the stop-start symbol with a line through it.

When I remember, I deactivate it as soon as I start up, I can't see what good it does apart from the theoretical drop in emissions and consumption (theoretical).

Not as i'm ever likely to own a car with dubious faff like this, perish the thought, but if in the nightmarish event i somehow end up with such a device, it will be the very first thing i find a way of permanently disabling.

Would be interesting to see figures over ten years of real use, fuel savings versus all the extra costs involved including initial extra costs when built, i'd wager the higher cost of a new battery alone would wipe a good chunk of likey fuel savings out.

The savings depend on the hours the system has operated, the information is stored and can be seen.

Some owners have posted very large numbers.

Probably the same people who feel the need to quote consumption figures to three (or more) decimal places.

I managed to disable this stupid system in one of my cars and usually manage to remember to switch it off on the other. One the occasions I don't do this it seems just as likely to forget the 'start' function.

Daft use of technology, solely to improve the EU numbers.

I agree with generally negative views here. My getting it checked by the dealer was to make sure no underlying problem and it was under warranty so free of charge. I was also c***cerned whether if fitted such systems are tested at MOT. However they aren't tested so no issue there. If anyone finds a way of disabling it, other than pressing the disabling each journey, I'd be interested. I am sure I read somewhere that a "no idling" law was being considered and if that comes in we'll all have to use such systems or turnoff manually. Time to invest in battery manufacturers shares if it does happen.

I woulnt miss it, but i do find it quicker than using the key to restart, with my system i just dip the clutch the car starts very quick and away i go, some traffic lights on my jorneys are quite long on red, so turning off is what i would do anyway.

But the system is clever in that it will not turn off if the battery lacks charge on i-stop.

Stop/start is bliss on diesels - for the slence.

That depends entirely on what sound proof measures the manufacturer has put in place.

I also had the stop/start light come on but after driving 200 miles on a Friday and two short trips over the weekend with maybe about 5 stop/starts the battery was so flat I had to jump start the car.

Having put it on charge overnight it was fine for another week but now the warning is back on.

I can understand the system not liking short journeys but surely a 200 mile drive would fully charge a battery to last a weekend.

By the sound of it your battery is old/failing, or your alternator is failing/belt slipping, and the battery is not getting charged up.

Nothing to do with a stop/start system, most likely.

Also check HJ regular advice re suspect interior lights etc causing a battery drain.

I cheered when my new 2015 CRV came without stop/start. Hate the damn thing. Used to disable it at every opportunity on my last car.

We've got a CR-V that's around 4 weeks old. Sometimes the stop-start doesn't activate, even when the car is fully warmed up, for no apparent reason, although most of the time it does. I don't see it as a big deal. When it does activate, the engine always starts when the clutch pedal is depressed to move it into first, so why worry?
