Solid light yellow means the conditions are not proper for a stop engine. I had this happen very frequently after my battery issue. Once the conditions are met it should start returning to normal operation. I've never seen my yellow indicator when it didn't shut off actually flash.

 

Sounds like normal operation. It's Winter, so cold weather is causing some of the conditions that don't allow ISG to operate.

 

The manual must be wrong as I get no message when it fails to activate due to inappropriate conditions.
The fan speed, air temp, battery charge and so on all make a difference.i noticed it was not kicking in and realized it was because I had the blower AC on full cold and high speed. Adjusted it down a notch and the ISG kicked in at the next light...

 

If the battery is loaded with accessories running, ISG will not activate, with the seat heaters and heated steering working on mine ISG will not activate. I don't get any message either.

Pat.

 

The manual says the ISG should operate:

1) If the seat belts are fastened.
2) If the driver's door and the hood are closed.
3) If the brake vacuum pressure is adequate.
4) If the battery is sufficiently charged.
5) When the outside temperature is between 14-95 degrees.
6) If the coolant temperature isn't too low.

I can't correlate what's happening to any of these. We did try turning all of the accessories off (except the radio). Anyway, I appreciate hearing that some of you are seeing this happen. I just wish the owner's manual would be correct.

I.S.G. is also contingent upon engine temperature among the myriad of prerequisites necessary to activate it.

 

Add me to the list of people that do not like this feature. I wish I could disable it. I have found the ISG does not work if the fan speed is at 2 or faster. It sounds like yours is doing what it is suppose to do.

"Add me to the list of people that do not like this feature. I wish I could disable it. "

YOU CAN! I've already documented HOW to do it, so I won't repeat that again.
It cost me Nothing and just makes life with my new Soul a little easier.

Happy New Year

 

It has become a reflex for me. Turn key to start car, then press the ISG button, and then put on seat belt and go. It's just a habit now.

 

I had a problem with the ISG after purchase. I had the dealer keep the car overnight for a full battery charge to make sure it was charged to tech/spec levels. All good now.
I city drive and am used to the ISG function and in fact, kind of like it (I'm in the minority I know)

 

just bugs me that there's another electronic malfunction for this new vehicle (it's been in twice for software u

Has anyone else had a problem with Idle Stop-and-Go?
[/QUOTE]

This is a great article explaining the Idle Stop-and-Go and the circumstances under which it will not work:
https://www.import-car.com/hyundai-...m/hyundai-idle-stop-and-go-isg-start-stop-systems-are-here-and-out-of-warranty/

 

I love how it works,living in Phx,and driving in and around town,the gas savings are real.It amazes me that this thing will return low to mid 20’s bombing around the surface streets.Even getting into some good boost from time to time lol

I bought this thing purely for it’s features,mileage,and waranty,and configuration(see roomy box).

Bang for the buck,a Soul is a great commuter,and allows my Hellcat to not have to pull daily duties.

My average 250 or so miles a week cost me 12-14 dollars a week in gas because of such technology.Is it perfect,maybe not.But I still think it’s a solid worthwhile feature.

 

I don't understand the hate for ISG, it works seamlessly in my car.

Pat.

 

As you can tell it seems your ISG is behaving normally.
I have come to appreciate the ISG. Being able to get 36mpg in a 200+hp turbo soul in bumper to bumper traffic every day is simply amazing to me, and absolutely worth it.

 

I like it. Mine has never really flashed. Even at 33 this AM if activated.

 

Like some of the other comments, I couldn’t figure out why I was solid amber in the display, with the button lit. (1,100 miles 2020 Soul).

Taking off from a complete stop amber light and button light disappear as expected. I don’t know what conditions weren’t being met, but presumably it was something.

I too thought something was wrong with the ISG even though I hate the feature. I have experienced it working (green indicator) with engine shutoff, but would have expected that to be more frequent than what it is.

Nothing wrong with mine! I hated it,,, I killed it,,, Nothing wrong!

 

I’ve also found that it will not work if the defroster is operatii also.

 

ISG is needy, sporadic & does what it wants to, even when it makes no sense.

I dated a girl like that in my 20's

 

You too? I wonder if it was the same girl. ???

You still driving that old, out of date, 2014? C'mon guy, grab a 2020 and join the In Crowd.

 

Man I would grab a 2020 (stick shift) if they hadn't decontented it so badly. Its not the same vehicle.

If it had the Car Bits listed in my signature line, I'd be all over it.

My 2014 Base has features the higher end Gen3's have or missing altogether across the line up.

I'm secretly holding out that they introduce a 2021 GTI Turbo Soul with stick (say what now?). They just did it in the new Forte GTI. Has upscale features too. They are finally getting the message that stick shift drivers don't necessarily want a Base Depression Era ride.

Kudos to Genesis for realizing that too!

Hope you're having a relaxing afternoon.

 

I guess that I’m in the minor here too. I have a new 2020 EX Eco and have gotten used to ISG. I like it. I’ve found though that just shifting your foot ligently while stoped will cause the engine to restart. Also if the defrostEr is working ISG will not function.

 

There are some here who don’t like the Start--Stop feature. This is the first car I’ve owned that has it. I picked up a 2020 EX eco 5 March and have put about 400 miles on it. My average mpg is about 34-35 mpg. The start—stop doesn’t bother me at all. In fact, it’s growing on me. There’s some here who say it really save gas. You may find this interestin.

Let me know how much you like it after you have replaced a couple of starter motors...

 

I stopped on a hill, when I tried to go the engine started then died instantly causing me to roll backward. Now I turn it off as soon as I start the engine

 

Had a similar experience. Foot off the brake, and a stall. Can’t duplicate, but definitely a concern.

My 2020 GT-Line is a year old now and I have not had a single problem with idle stop and go, it has worked flawlessly, I still don't understand the animus against it, or the other so called nannies for that matter. The only thing that took a bit of getting used to was the lane keep assist.
I have read that if all cars were equipped with the so called nannies that it would save 11,000 lives a year in the US.

We shouldn't be waiting on autonomous cars when the tech available to us now could save countless lives, if we let it

Animus? The vehicle stalled during the ISG operation...in traffic.

Animus? Is that anything like "I hate that damn thing!" ?
I just permanently disabled the ISG on my car, and I've not looked back. Now it drives like a real car.

 

First week of ownership, about 500 km driven, my ISG didn't work for a whole day.
This might be because I've been playing with the infotainment unit with the engine off, and it drained the battery a little. I was also only driving local streets.

Then yesterday, I drove on the highway and the ISG started working afterward.
