Idle Stop and Go Issue

[Smolenski7]

I noticed a problem with my new Telluride lately, specifically with the Idle Stop and Go.

Many times, not every time, I am stopped on an incline the car will turn off. That's fine. However, when I release the brake and step on the accelerator, a very loud grone comes from underneath the front of the car.

I have tried to replicate the problem when the system is turned off and can't, so I think it has something to do with it.

Before I call the dealer, any idea what it could be?

Maybe the emergency brake engages on an incline in that condition.

Maybe. I'm really not sure. If that's the case then it seems like a software problem?

I have noticed that the stop/go on mine only seems to work occasionally. Anyone else have that experience?

Got this from another Telly owner. Lists specifics for when ISG engages or does not engage.

I noticed during the cold season when you have the heat or defrost on, the auto stop feature doesn't turn on as often.

The yellow "A" comes on when I stop, but does not flash. Eventually it goes off while I wait at a stop light. I don't see anything in the manual about that.

I suspect you are probably on to something with the colder weather and the heater being on. Probably too big a draw on power and/or programming to keep the HVAC blowing hot air. I'll turn the heat off and see if that makes a difference.

Thanks.

My "A" is orange when on even ground and seems to turn green when at an incline or decline.

I've been having the same problem. Amber IS&G indicator 90% of the time. I purchased my Telluride on 10/29. I took the car to my Kia dealer on 12/21. They had no answer for me. Well, I should say their answer was "according to the manual, it probably has to do with the temperature outside and it's too cold so you'll need to bring it back when the temperatures are warmer". To which I replied, "I purchased the vehicle in October and we had some pretty warm days since then (I'm in NJ and we had some 40-50 degree days after I purchased the vehicle) and the amber light still lit on those days." I was met with a blank stare. Funny thing is the next day I decided to turn the ISG off completely yet it continued to go on but this time the indicator on the dash lit up GREEN and the car actually shut off when I was stopped at an intersection or green light. Go figure. But it was frustrating because I wanted to turn the feature off entirely but every time I hit the button to turn it off and the light on the center console was lit indicating it was OFF, whenever I stopped the car, the ISG kicked in and registered GREEN. Can't figure this out. But since then it's been lighting primarily amber except for today. It's 37 degrees and it actually worked today (AND I have the heat on so I don't think that's the problem). Yet on warmer days it didn't. Again, Go Figure

With all auto start/stop vehicles, when about to take off let up on the brake slightly to where the vehicle is still stopped and the engine will turn on and then hit the gas. If you attempt to swap you foot over fast from brake to gas you will be attempting to launch a vehicle that is starting up. Doing this a lot will cause major issues in the future. If you are in a hurry or very steep hill and do not want to do this then just turn the function off while at a light and the engine will turn back on.

I just turned the ISG off completely. In another thread I saw a guy who fashioned a small grey plastic wedge from the top of a cream cheese container and placed it in the space between the on/off button. Now, whenever I start the engine, the ISG switches off without me having to press the button everytime. The groan hasn't happened since.

I find the driving experience to be much more pleasurable bc I'm not always wondering if the ISG will turn on.

I've also started tracking my gas, also in another thread, with the feature off. It definitely has gone down, but I think it has to do more with the weather and the manufacturers switching over to a winter blend of gas than the ISG being off.

Mine seems to be totally sporadic. never thought about turning it off. So, are you saying that when you turn it off it shuts the car down every time you stop (in other words, it works when you have it turned off)?

Mine definitely isn't working properly. Well above freezing, fully up to operating temperature, and no heat on and it isn't working. Yellow light comes on for a bit (doesn't flash) when you come to a stop and then goes out and the engine stays running.

This is a long post but this may be of help to some that are having the same issue as I had. I explained in detail below because many are having the same issue. I personally think many of the ISG problems are caused by the battery sensor. If you google battery sensor you will find this can be a problem on all vehicles with ISG.

I have owned my Telluride for over a year now. I have had trouble with the ISG every since I first drove it. It has been to the dealer numerous times. The dealer diagnostic tests always point to the battery being the problem. I was always told I don't drive it enough to keep the battery fully charged and that is why my ISG did not work. They would charge the battery and it would test okay and the ISG would again work for a few miles and then stop working again or it might work at a red light and then the next red light it wouldn't. This is what many of you are also experiencing. What finally caused me to escalate the problem to KIA customer service was when I took a nearly 1000 mile 3 day trip and the ISG never worked for the entire trip. I took it to the dealer upon my return and the same thing... battery not fully charged. I knew that could not be right so I called KIA customer service and opened a repair ticket with them. They told me to take my Telluride to another dealer for a second opinion and if they couldn't fix it to have them call tech support. I took my Telluride back to my dealer and told them what I had done and what I was told and asked if they wanted to call tech support for assistance before I took it to another dealer. They agree to get tech support involved at that point. Their diagnostic test still indicated a low battery charge. They contacted tech support and was told to replace the battery sensor to see if that would resolve the issue. The battery sensor on my vehicle left the factory defective since my ISG never worked properly. It was replaced and now the ISG on my Telluride works as it should. Once the vehicle reaches its operating temperature, and I don't have the blower above the third speed, it works every time I stop.

This could be your problem also, so it is worth a shot to discuss this with your dealer if they diagnose the battery as being the problem. Dealers were replacing batteries left and right and KIA is now making it very difficult to get a battery replacement authorized under warranty. A side note... if you replace your own battery without taking it to a KIA dealer this can cause ISG issues as well without recalibrating the system.

This was very helpful as I have YET to figure out my ISG......I haven't had my car for 2 weeks even and it seems like the ISG has only worked a few times. We have had bitter, frigid cold in Kansas this last week and I was wondering if that had anything to do with it - just too cold to do the auto shut off when stopped. But my WHEN it seems to work - the light on my dash is actually orange and not green..............and the off/on button on the console will just randomly come on or off as it pleases basically. So I am completely confused as to whether it is on or whether it is off half of the time.

I own a 2024 telluride. Don't know if its like BMW's (i've owned at least 8) but their computer keep the car running "on choke" until the car warms up to keep it from stalling but of course you use more gas. I noticed on a cold morning on my Telly, if I have the ISG so the engine stays on, and i am stopped at a traffic light, the mpg goes down by 0.1mpg about every 10 seconds. If I make the same trip in the afternoon and the same conditions at the red light, my mpg goes down 0.1 in about 25 seconds, telling me the engine computers are tuned for weather.

Your BMW’s where carbureted?

 

[Rhalama]

was not a "choke", just felt like it as the computer made the rpm's higher. Bad choice of words.
