Idle stop not operating on new Stinger GT2?

[NYLAWBIZ]

I know, when it works, I’d love to set a delay factor. The way it, when it works, shuts off is very fast. I’d love to tell it delay 5 seconds then shut off. While any delay may not be perfect, I’d like to be stopped a few seconds before it shuts. I find it too quick, when it works.

I think we have to have faith that the settings are set for optimal fuel savings. Off course, if it doesn't go on, then there are no fuel savings.

Hey this is important function parameter for Idle Stop and Go that I have confirmed now though my use of it. When the car is at an incline lets say your stopped on a hill facing up Idle Stop and Go will display the orange light. It will NOT shut the car when the car is on an incline and sometimes even slight inclines prevent it from shutting the engine off. When stopped facing downhill depending on how steep the stinger is it will also not come on.

That's crazy! Well, my ISG started working, but now it isn't again. Going to bring it into the dealership and let them have for for a few days to get it figured out.

Mine is back to being mostly not working. I’m figuring it’s a battery level thing mostly. Battery not at 100% not gonna do it, wouldn’t be prudent.

My prior car (2013 BMW 5 Series) had this and it worked at all times. Never had this issue. I still believe there is a software bug fouling things up.

I wish mine would "break". I honestly can't stand ISG. I do too much stop and go traffic, so half the time it goes orange and doesn't turn off and the other half it shuts the engine off and restarts immediately since I come off the brake pedal. I keep having to press the button every morning. Not really a "issue", I just would love to have a option to disable it

 

[BlaydeX15]

I've also noticed that it doesn't turn on below 50°F, for anyone who lives in the middle 2/3rds of the USA right now. Lol.

OK - Update:

Well, as things have it, I think I figured out why the ISG (Idle Stop and Go) stopped working. It so happens that a bracket on my iOttie wireless charge broke:
https://www.amazon.com/gp/product/B0754NDNT8/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

So, I disconnected it, and viola - the ISG (Idle Stop and Go) started working. It appears that the wireless (induction) charging system is a big enough drain on the system that it prevents the ISG (Idle Stop and Go) from kicking in. I did a little more experimenting. I decided just to plug my Samsung Note directly into a USB port (as I normally do so as to have Android Auto operable). The ISG (Idle Stop and Go) worked for about 45-60 seconds that went yellow - it seems just having a phone connected to the car is enough for the ISG (Idle Stop and Go) to disengage within a minute. I played around some more and confirmed that if climate control is cooling the car, the ISG (Idle Stop and Go) also does not engage (as mentioned in the owner's manual).

Needless to say, I cancelled my appointment with the dealer, until I spoke again with KIA, which I did. KIA said well, bring the car to the dealer so the dealer can replicate what I discovered. I will do that when I have a chance.

So, the question is, is this acceptable? Should the drain of a cell phone charging be enough to disengage ISG (Idle Stop and Go)? Especially since you have to have the phone plugged in to have Android Auto (or Apple CarPlay) running? I think not, and I intend to go to the dealer, have them replicate this and then pursue it with KIA. Probably all that is needed is a software tweak. I cannot imagine a charging cell phone would risk draining the car battery within a minute.

The community's thoughts on this would be most appreciated.

Thanks

Now that the weather has cooled, I am no longer using air conditioning and have disconnected my iPhone as well. Still, the ISG is NOT working, so not sure that this is due to a battery drain. I also believe it is a software issue. Will be bringing it in soon for my firsts service, so will have the dealer look it over. Bottom line, I don't particularly like the feature, but since it is available, it should be working and give me a choice to use it or not.

My GT2 is at the dealer right now for that issue (also to replace cracked trim on steering wheel). This is the second go around. The first time, they couldn't figure it out, so this second time they are working with factory support. Have a loaner car for that reason - at least a new car for a loaner, a Rogue with 1,400 miles on it. This is day two it is at the dealer.

Look, I can say my ISG generally worked fine. Last month I was away and I left the car parked for 3 weeks. When back, the ISG didn't work for at least 2 day, at all (short drives in traffic of a few miles). I believe that during those 3 weeks the battery discarched quite a lot and for those 2 days it was not good enough for the ISG to work. I then drove a bit more and for a bit longer (not in insane traffic) and now it works perfectly again.
This to say that in my opinion it is strongly related the battery. Maybe yours is faulty and does not keep the charge, or maybe there are some other issues with the electrical system, I don't really know. But I would go first to the source of the problem (the battery). If you can, replace it with a new one and see what happens, or at least check it and be sure it keeps the charge. Then I would unplugged everything from the car (phones, dash cams, and any other electronic) and see if these were the problem. If it works fine, now I would connect them back one at a time and drive for a bit before connect the next one, and so on to see if the ISG works. U might find that one of those causes the drain and the ISG to not work. There was a post of a guy that said this happened to him. ISG never worked, and then he realised the problem was caused by some device (don't remember which one) that he connected to the car. If all of this fail, then you definitely know the ISG is faulty, and Kia can probably replace the parts that are damaged.
I hope it helps. keep us posted. good luck

On a related note. Oh and my ISG still mostly doesn’t work, either. I notice the car will not let me listen to the radio for more than a few minutes after parking. First it warns then it shuts down. This is the first car I’ve had that does this. I’ve had others with nicer than average factory radios and I can sit and listen while waiting as long as I want and the car always started when needed. I’m guessing there is a lot of drain on the battery in this car. Maybe it should have been a dual battery car?

Confirmed. Since day one. It's a Stinger thing. Maybe two batteries, but then you have to find room for the 2nd battery. I'll take the extra room and idle my engine when I want to listen to music, while waiting for my wife to finish her errand, in either an excess of heat or cold, both of which we have in plenty.

Well, after the dealer had the car for a few days, they said everything is operating correctly. The following is an information sheet on ISG proper operation.

so what was the problem?

 

[MikeysGT]

Has anyone found a solution yet? Mine worked perfectly for the first two months then all of a sudden, nothing. It will never engage. Supposedly, all of the conditions are being met for it to work. All I have plugged in is my phone, which I don't even plug in half the time. Temps have been in the mid 50s mostly during the day and it still won't work even with all climate options turned off. It would be nice to have since I often have to sit through some long lights, especially if I'm a few cars back in line because the number of people who actually move once the light turns green I think is about one in 50 . The light is green. Get off your phone and drive.

I'm convinced the vast majority of problems people have are with battery discharge, as the battery has to be near peak capacity for this function to run. Mine stops working after a few weeks of city only or mixed local driving, then resumes working after an extended run on the highway charges the battery back up. Plenty of power is always still available to start the car, run accessories, etc. - but not ISG. People have noted that even plugging in USB phone chargers can be enough to keep it from operating (presumably after the battery has already discharged somewhat from peak capacity).

Last week after the ISG function had not been working for a few days, I put a battery float charger (CTEK 2.2A) on the car for a day while I was driving another vehicle, and charged the battery right to full. ISG has worked 100 percent of the time ever since - and I fully expect if I continue driving relatively short local trips, it will eventually reach a point where the battery discharges enough for it to stop working again.

To see if that is the case with yours, hook up an automatic/float charger and leave it until it reads a fully charged battery - unless you are in a hurry, charge it at least through the evening and overnight at a low current (e.g. 2 amps). The battery is a big sucker, so it takes a while to fully top up.

No need to uncover the battery in the back - a positive charging contact is under the engine bay plastic fuse cover in the rear passenger side corner, and a convenient negative contact 'bolt' is midway down on the passenger side of the engine bay. When I have time, I'll be attaching a CTEK permanent connector lead, like I do with vehicles that spend months in winter storage - makes hookup a simple one-click affair.

I would say chances are very good that will restore your ISG to full operation ...until short operating cycles discharge it sufficiently again.

You are probably right.. I drove about an hour and a half on the highway yesterday and fully expected ISG to work again once I got back home. Nope. But today I made a couple short trips across town and it worked like magic every time.

It would be nice to have it stop working especially when I forget to hit the button. I wouldn't complain at all if mine stopped working.

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.
