Problem with my 2012 Telluride SX

[larjan]

I ordered my Telluride in March 2020 and received it in late August as a 2021 model. The dealer won't honor the original purchase price so I paid a small increase of $340. After waiting 6 months I wasn't willing to go without a vehicle any longer.
I'm happy with the Telluride with the exception of one problem the dealer wasn't able to fix. The Idle, stop and go (ISG) isn't working properly. With the system on, the first time I press the brake pedal the system turns off and the instrument cluster shows a yellow A. I reset (press the ISG button) to activate the system. The next time I press the brake pedal the system shuts off and the yellow A reappears in the IP.
Is anyone else experiencing this problem? Is this a recall software problem? This is my second KIA and I like the dealership, but this problem is very frustrating!!

Page 5-46 of owners manual. ISG is very finicky. Make sure your battery is fully charged.

Thanks for your reply.

This is normal operation. The yellow A means the system is working but conditions have not been met for shutoff.

Must be an early prototype model issue

Has it ever worked, under any condition? Do you ever see the green A? Mine works fine, meaning half the time it doesn't engage (all requirements not met) and I get that yellow A. The other half the time, it engages. With either the yellow or green A, it's working in my case.

1. Drive until the coolant temp warms up. Needle in gauge usually almost at the middle.
2. Turn off climate control
3. Don’t expect it to activate when it is lower than 60 degrees or hotter than 80 degrees outside
4. Don’t expect it to activate while using cruise control.

If these four conditions are met but ISG still isn’t activating, buy a battery charger/maintainer. Charge until the battery is full. Repeat four conditions above and it should work.

If not, ask Kia to replace your battery.

Once you confirm ISG works, use climate control as normal. But know that when your set the cabin temp too far from outdoor temp, it may take a while before ISG will activate, or it may never activate at all. Or it may start the engine shortly after stopping to try and maintain cabin temp settings.

You also don’t need to fiddle with the ISG off button. Your Telluride defaults to on position every time you start the car.

Maybe just me, but i disable it everytime i get in the car. I feel like it will over work/strain both the starter and battery having to contsantly restart the engine. I'd have to try it fir a couole tanks to know, but i also feel like fuel savings aren't worth it right now.

Sorry I'm new and don't know what you mean about moving into the Technology category. Where do I find that category?

It's housekeeping. Look a couple of lines above your original post.

Further update concerning my ISG problem. I reviewed the manual and met all the requirements for the ISG system to work properly. Today the following happened: Drove and the ISG system was on (default setting) when I stopped at a light the button turned yellow (0ff) and the yellow A appeared on the instrument cluster. Light turned green and started driving and the ISG button reverted back to the default setting and the yellow A disappeared from the IP. Stopped again and the same problem, ISG was off and the yellow A appeared on the IP. This same sequence happened 3 or 4 times before I got home. Definitely a problem! I'm going to wait until spring to take it back to the dealer, maybe by then other people will have the same problem and there will be a fix.

Based on your account, it looks like the system is in fact working, that’s why you get the yellow A in the instrument cluster. Now if the yellow A was blinking or you got a persistent yellow A that never went away, that would signify a problem.

Your most likely culprit is the state of battery charge, as discussed above. This is probably happening if you infrequently drive your vehicle and only go for short trips whenever you do use it.

Just because it isn’t actually turning the engine off at a stop doesn’t mean the system isn’t working. A properly charged battery will surely get it to operate as you desire. And if your driving habits do not result in a sufficiently-charged battery for the system to actually shut the engine off, you’ve effectively removed one of the top complaints people have about Tellurides and many new cars (although the Tellurides ISG system is very smooth and non-obtrusive).

Light turned green and started driving and the ISG button reverted back to the default setting and the yellow A disappeared from the IP.

If ISG is turned on (default state) the button light follows the dash light, it turns on when the dash light turns on, engine may or may not shut off based on the operating conditions listed in the manual.

If you turn ISG off (one press of ISG button) the dash light does not illuminate and the button indicator stays illuminated indicating ISG is off, in this state when the car stops the engine does not shut off.

Do if the button light always on it indicates ISG off; if the button light illuminates at a stop it indicates ISC is on and will shut down the engine if the other required operating conditions are met.

It sounds like your is working properly; however, the engine is not shutting down means one of the other operating conditions is not met. As others have stated its likely Battery charge level.

Charge your battery and I bet it works; then you can do what I do which is turn it off as soon as I start the car.

Yes I had the same issue with ISG and the battery not fully charged. Once the battery was on a tender and fully charged the ISG started working properly. I keep my Telly on a tender when not driving for several days. Others here on the forum have written about the battery drain and the effects on the ISG.

I keep my Telly on tinder

Wow, you let your Telly be promiscuous like that??

Just doing their part to increase the supply of Tellurides!
