Idle stop not operating on new Stinger GT2?

I second this. It's 31 degrees outside today and mine was still shutting off at stops. I hate when I forget to hit the button to stop it.
We only need one reminder, and then push the button; and for the rest of that drive there isn't any ISG. I don't see any problem with needing to push the button once if I happen to forget once.
 
On my GT2, idle stop was iffy, then more or less stopped working last summer. I initially noticed difficulties in getting the "on/off" switch to change -- had to press it twice or more to get it to turn on or off. Shortly after that, idle stop ceased working at all, irrespective of battery condition or anything else. Most frustrating of all, I took it in last week for service, was told no problem could be noted -- then when I went to pick it up, I was able to view the same issue before I even left the service dealer's parking lot. So it went back in the shop, *really* frustrating. Purchased vehicle in February. Seems like maybe this is a widespread problem, in any case not just me!

It is only a problem, imho, if you can't stand a feature on your car not working: because things that don't work are hateful. That would be me, generally. But if ISG ceased to function altogether on my car, that is probably the single feature that I could shrug off; not remotely a deal breaker. I've referred to it as a gimmick; a "green" feature for political purposes, rather than a serious fuel economy tool.

But I don't see how the service department can assert that it works when it doesn't. Did you go for a drive to demonstrate that it never works at all?

ISG is a mixed bag. If you drive a significant amount of freeway, it will work. I do a lot of Cory driving and it barely works. I drove 200+ miles on Saturday. Today ISG started working again, at least for now. I didn’t go anywhere in Sunday so it didn’t mind sitting as long as the battery got a good long run on Saturday. This is the pattern I’m used to. I wonder how other cars, other brands handle this?

But that's the single driving condition furthest away from needing/using ISG (Idle Stop and Go). :p
I mean by driving that amount of freeway, it charges up the battery better. Then ISG works. At least for awhile.

Im glad I'm not the only one who thought this was happening.. Almost every time I have to press it twice to turn it off, even though it never works anymore anyway. It worked for me all summer but quit when it started getting cold. Which I can sort of understand to a point since we generally tend to use more accessories when it's cold out (defrost and heater, heated steering wheel, heated seats, etc..) which is a bigger strain on the battery. I drive 25 minutes on the highway to and from work every day and even that's not enough to get it working again. It took about 45 minutes to an hour to get the battery charged back enough for it to work the one lone day I had it back since it got cold out.

Interesting cause of my problem -- a bad battery. Though it was essentially new and the car has only 4K on it, the reason my idle stop never worked after last summer is that the battery would not charge much past 45% under any circumstances. I knew there was a problem after I drove two hours on an interstate on a warmish day, and idle stop still did not work. I'm glad I got this fixed, not just for the idle stop issue but also cause the battery was failing in general. Idle stop works well now, though not always as it's winter and I do more around town driving than highway.

Was the dealer able to diagnose the bad battery? If not how did you? My ISG rarely works and only after a long freeway jaunt. I did one on Friday and it’s been working for a day now. I’ll definitly ask for that test on the next visit.
 
Hello Guys. I'm new to the forum. Just picked up my '19 Stinger GT on Dec. 22nd. I found this thread after taking my Dad for a ride and trying to show him some of the features, including the ISG that didn't activate when I wanted it to. After organizing some of the paperwork that came with the car, I found this card from Kia that was banded to the gear lever with some others that has information for the ISG:
ISG2.webp ISG.webp

I don't know if it will be much help with what's already been discussed, but at least it eases my mind that there are some factors that keep it from activating. I still turn it off anyway.

My ISG works flawlessly. I think the big issue is that most Stinger owners don't understand how the ISG works. The ISG will only work when the car's motor is warm and up to operating temperature. By default, when you first start the car, the ISG system is on and the ISG light is off, but the system is waiting for a warm engine, so until then, your motor will not turn off when you come to a complete stop. Once the car has warmed up the system will be ready to stop the engine upon a complete stop.

I can assure you that my motor is/has been warm and the system does not activate. I would, however, like to know what the high and low ambient temperature thresholds are for the system not to activate. I've had it not work on 60 degree days before.

Greetings. That was pretty informative for a first post; nice single source for ISG (I've not seen that card before).
 
I had my recall worked on so I had the dealer check into the Start Stop not working... the response so far? "We are dumbfounded as we can't find anything wrong..." they replaced the part which they thought that the pressure on the break pedal was not registering properly to trigger Start Stop... no fix though.... they even pulled a brand new 2019 GT2 and tested it... same problem. Battery is fully charged and loaded on both - mine and the brand new one. I think we are stuck.

As the originator of this thread, I figured I should chime in with how mine is going--my battery is shot and I have the dealer doing a warranty replacement of it while they do the recall inspection. Apparently my car's born date is Nov 2017 and it wasn't delivered to the dealer until late June 2018 (and I didn't buy it until September 2018) so the extended sit is of course only going to do great things to the battery--couldn't get it to crank at all last weekend.

The only good thing about the cold weather is that it helps me remember to turn off the isg. Get in the car, start up check, heated wheel on check, seat warmer on check, isg off check and go! In the warm weather I always forget to turn it off and there it goes at the first traffic light. grrrr. It is a blessing if yours doesn't work! Jmho

I wish I had that problem. That gets turned off first thing.

Sorry, but there are dozens of people here, including myself, that fully understand the system but have found it to be flaky and inconsistent - and that there is much more to the system, and when it decides to work or not, than just temperature.
 
My daily drive is about 5 km so my car never gets fully warmed up & idle stop & go never works. It defeats the purpose of saving fuel at stops if you have spend 10 mins waiting for it to warm up or drive on the highway or take a longer route to get it to work. There are just too many variables for this to be practical.
