Hi everyone, the auto engine shutoff feature stopped working when stopped at a light etc. Should i be conserned.
 
You are either not driving enough or your battery is week.
 
It will only shut off if certain conditions are met. Read the manual, it is full of useful information.
 
You should be thankful that it does not work, I have to shut it off manually every single time I drive.

My 2020 Telluride SX Prestige the ISG has not work more that is has. I know there are many different conditions that need to be met so the ISG will shut off the engine. It has been to the dealership 3 times to look at the issue. The last time they had the car 6 weeks, opened a Kia Techline ticket and the conclusion was it was not being driven enough to keep the battery charged to have the ISG shut off the engine.

However, during that 6-week period they loaned me a Kia K5, that engine shut off every time, once the engine was warm, and the driving habits were the same as the Telluride.

After getting the car back(3 weeks ago), I have been logging the duration and milage of every trip. We drove the Telluride over the Thanksgiving holiday 2.5 hours one way to the NC coast(about 150 miles). It did not shut off when we got to our destination and my feeling is that 2.5 hours should have charged the battery enough to have the ISG shut off the engine. The return trip it did not shut off either.

I know there are plenty members on this forum that would tell me I am lucky that it does not work. I don't need to hear that. This is a feature we paid for but does not work as advertised.

My next step, as told to me by the service manager, is to escalate it to Kia Customer Care. Do other Telluride owners feel I have a problem? Are there others that are having the same problem? Trying to get confirmation before I escalate. Thanks
 
I had similar symptoms and was told the exact same thing.

I bought my own battery charger and volt meter to do some testing of my own.

It turned out to be a bad battery that wasn’t holding charge properly.

It cost me $150 of my own money. Plus 200 km of driving back and forth as it took two trips to convince them.
 
I just go to any local auto parts store they do free testing and charging if need.

I had a similar issue with mine. They had my car about a week diagnosing and replacing parts. I think I posted here somewhere about it but if I remember right there was some signal that wasn’t being transmitted properly indicating that saying that a particular condition had been met.

Not very helpful I know. I’ll see if I can find more information about what was done.

Experiencing the same as you, ISG has only worked maybe 20 times in the past 3 years of ownership. Even when I charge the battery (roughly 13.1 volts fully charged), ISG will only work for about a day or two.

May battery will usually dip to around 12.3-12.5 volts with the car off, which apparently isn’t enough juice even when all the conditions for ISG to function.

When I rented a Ford Explorer recently while on vacation, the ISG worked every drive. Even better, the car would in addition, auto stop whilst fully stopped when the computer systems decided conditions were met for ISG. Whereas the Telluride will only engage ISG when you are in the action of fully depressing the brake pedal. If it doesn’t shut off there, it will not at all until the next time you brake.

I also rented an Infiniti QX60 and that car never engaged the ISG unless I turned off the climate control.

Where you able to check the new battery voltage? Curious if it holds a charge at or around 13 volts when new and the ISG is working.

Wow, those symptoms are very similar and the times it did work after about 2 -3 days it would stop. They changed the battery twice in the car with no luck. The service manager led on that he thinks it could be a 2020 issue only. He also mentioned he as a BMW he drives one a month and it turns off right after the engine is warm. Are you just living with it not working?

Kia does not seem to think they have a problem since people are not reporting it. There are probably more Tellurides acting like ours. I think I am headed down the escalation path with Kia Customer Care to see what they have to say.
 
Update on my end. I had them check the ISG while other work was being done. They told me that there are about 30 different parameters that the system checks before it engages, which I thought was interesting.

Anyway, they tested my battery and it came back as needing to be replaced. It’s supposed to have 800 CCA and mine is at 355 CCA according to the test. I haven’t had any issues starting the car but I’ll probably replace it soon.

What about this?


I have been thinking of getting this myself!
Just installed it. Not as simple as the online video shows. Removing the console trim was a task. Then putting in neutral and the car constantly pings at you until you are done. And doing the zip tie as a one-person job cut up my wrist due to the clips under it. Have someone hold up the console when doing the zip tie. When I do the other telly, I'll be prepared. Works great though....

Thanks for the tips!!!
 
I thought it was as easy as it shows on their video. It was warm and maybe that’s why.

If the orange light on the dash is turning on when you stop then ISG is working. The orange light on the dash means ISG would stop the engine but one of the permissive signals is not satisfied.

If an ISG related sensor or system error occurs, the yellow AUTO STOP indicator on the dash will stay on after blinking for 5 seconds and light on the ISG OFF button will illuminate.

There are many ISG permissive conditions in the charts below, some are impossible to check without a significant number of sensors or diagnostic computer connected to the vehicle.

ISG has very complex logic that is easily rendered inactive by only 1 of the many permissive signals not being satisfied.

I had a 2018 Kia Stinger and the ISG in that car almost never engaged (which I was ok with because I hate it), I drove the stinger on a 1300 mile trip and the ISG began engaging (engine stop/restart) all the time.

I attributed this to the battery being charged fully on the 1300 mile trip. When I returned form the trip and resumed my normal driving pattern (car used 2-3 times a week) ISG engaged for about 2 weeks and them went back to never engaging. I again attributed this behavior to the battery charge condition.

I have a 2022 Telluride now and it almost never engages ISG and I have the same driving pattern of use 2-3 times a week. My Wife's 2021 Telluride is driven every day and ISG engages frequently (I turn it off when driving that car).

My conclusion is Kia ISG is a finicky bitch of a system that is overly complex due to the many permissive conditions able to defeat it.

Notice I said "ISG engaged" and NOT "ISG not working", that's because ISG is working as designed when it does not stop/restart the engine based on one or more unsatisfied permissive signals.

Most of the posts I have read on this forum dealing with ISG issues were resolved with a battery charge or battery replacement.

I agree with @Tellthemride, I recently rented a Ford Expedition for a week and the ISG in that vehicle worked way better than Kia's system
