I'm just wondering whether on my many trips I'm ever stopped long enough for this to be a worth while addition.

Besides the odd ocassion when I'm waiting in a Q to fill up at the petrol station the only other longish stops are at traffic light.

I know in UK it reduces the Road Fund Tax but .......................

I'd be interested to hear other UK owners thoughts.

I saw an article from a swedish paper where they tried to calculate how much you'd save if you used a start/stop system under favorable conditions  with lots of city driving. Unfortunately I can't find the article right now, but if I remember right the result was that in a year, you'll save a little under 1 liter of fuel, 0.9l if I remember correctly.

I wonder whether it will still be a selling point in 2 years.

I still have the opinion that this will be a bug bearer if it stops working and the cost of repair will be expensive.

I recall reading something similar. Coupled with the additional manufacturing cost of the battery/alternator plus all the added electronic control systems and sensors, is ISG really all that "green"?

yep ISG only really worthwhile for the lower road tax band, thats about it.....

Maybe we should rename this thread "i30 fairly dumb stop and go"...

or "very Idle stop stop and go"

UPDATE: well Hyundai called me late yesterday and said they replaced this part 'wiring extension kit' but its still not working, so they looking into other reasons why it may not be working. So the car had to sleep overnight at Hyundai, lets see what they got to say today. Maybe I should just tell them to just disconnect the damn thing, its not making much difference whether its working or not working......

MMMM about to leave a deposit on a new i30 cw tomorrow. The first of the ISG facelift models are about to land on Irish soil or so I have been told. My main reason for opting for the ISG was the fact that it lowered the road tax from €156 to €104, but looking back on previous posts I hope it does not come back to bite me 

Having said that, the 5 year unliimited mile warranty should set my mind at ease.

Roll on January the 4th

since my recall, the ISG is working very well, all i can suggest is that if it doesnt work like after 15 to 20 minutes of driving then there is a problem and you need to do recall

once recall is done you should be fine

I have been watching this ISG carefully to see when it works and doesnt work, I have noticed a few things. Now there is a long list of prerequisites for it to work which was listed in a previous post. But in simple terms you will notice the following:-

Below 6 or 7 degrees celcius it generally doesnt kick in due to cold weather which is fine as I sure certain temperatures in the system need to be reached for it to work, perhaps the coolant hasnt reached a desired temp for ISG

So during winter it kicks in less often and in summer it works very quickly even after 5 minutes of driving sometimes. Winter driving above 6 degrees could take 20 minutes of driving.

The engine temperture does not have to be at the 90 degree celcius for it to work it can be less than 90 degrees , mine has kicked in at 60 or 70 degrees

In winter when you have the heater on and the ISG kicks in, it will blow all the warm air out and start to blow cold air on you after about 20 seconds, which can be a bit annoying so you may have to switch off heater at long red traffic lights.

I have also noticed when the engine restarts the headlights flicker a bit due to the power been drawn from the battery, small issue though.

Overall, I would recommend the ISG option not only to reduce road tax but to save a small amount of fuel as well. There is a button on the right side below the headlight levelling button where you can switch OFF the ISG if it annoys you, sort of like a bypass. Luckily this does not affect your road tax hey?

Good result, glad its working now.

Thanks for the update was wondering how you got on..

I noticed that ISG on my car doesn't react to cold weather any more. It was ~ -15C and I was very surprised when the engine turned off at the red light. Also it looks like it notices that it is cold outside when starting for the first time (ISG button lights up and engine won't turn off), but if you leave the car for some time and start it again, ISG becomes activated.

Will have it checked out on my 1st year/20000km service.

Hi all great to read that I'm not the only one suffering from Hyundai's ISG.
I tested my battery at 12.6v no stop start.so after reading about the way  it charged I turned out every thing and 3rd geared it down my local massive hill (3times) pulled up at home and hey presto stop start was active 
Thanks all
Phil.

Great that you solved your problem

For future reference I'd suggest looking for a more recent topic or starting a new one, being 8 years old and concerning models older than your own might not always be relevant

I've heard Hyundai are going to rename their ISG as Insipid Stop and Go.. (It isn't very good!) 

[chrisdarl]

Incase it helps anyone, my autostop had never worked since I owned the car (2nd owner) but it turned out my battery terminal connection was slightly loose, one day I tightened the nuts and it's been working daily since! Worth a check for anyones thats not enabling?

[Dazzler]

Thanks Chris. Appreciate you sharing that.
