I just bought an sx and it works fine. Sync the back with the front and stays synced every time the vehicle is started. I have not tried to see if it stays off because it helps cool (to hot to try heat yet) the entire vehicle in a hurry with it always coming on. I didn’t purchase for the prestige package.

Rear AC question
- Thread author Redbeard
- Start date
That's odd to hear Rigit because I have always had a different occurrence with my SX (also non Prestige). The rear AC never automatically comes on when the vehicle is started unless I had turned it on during the prior trip because someone was sitting in the 2nd row and then on the next trip, there is again an occupant in the second row. If there is, the rear AC will automatically be on again. If the 2nd row is empty, it reverts back to only the front AC being on even if it was synced when the vehicle was turned off. If the rear AC was not on when I shut off the car, the rear AC will never automatically turn on even when there are occupants in the rear on the next trip.
Because of how it has always worked in my Telluride, I have assumed that AC system was designed to work in tandem with the rear seat occupancy sensor. Now I don't usually have anyone in the rear seats so admittedly I haven't tested the system in much detail in the 5 months I've owned it because it like how mine works and I would prefer not to be running the rear AC if there is no one sitting back there. Maybe there is a setting in the digital cluster to force the rear AC to be on whenever the vehicle is started and this is how yours is set or if there is some other reason for the difference in how each of our AC systems operate.
That is somewhat how ours works. It depends on how it is set the previous time the vehicle was running. Ours doesn't have anything to do with someone being in the back seat. If it is set to on, we have always had it on and synced, previously it will be on. If set to off it will be off the next time. I have not tried it to see if you turn off everything in the vehicle, including the front ac, if it will come on if it was turned off the previous time the vehicle was running. I feel sure if we turn off the back ac it will not come on the next time the car is started. I wouldn't expect it to anyway. None of our previous SUV's would start back up automatically if we turned it off. We have had mostly Suburbans, a Traverse, and one bad experience with a Expedition before the Telluride. They all worked this same way.
My last vehicle was a Tahoe that would always come one however the settings were left when the vehicle was shut off. But it was a 2004 model with all manual dial/knob controls so not nearly the same as current technology. But no idea why your AC will come on in the rear if no one is back there. Mine has never done that. It used to make me angry when I'd realize my Tahoe's rear AC had been running all day when there hadn't been anyone back there. Made the gas mileage even worse than the 14 MPG it was supposed to be getting. So I'm sure I would have noticed if the rear AC had ever been on in the Telluride when no one was there since the AC controls screen clearly shows when the rear AC is on. I'd have to look up at the roof mounted controls to see that in the Tahoe.

That is strange. We have only had ours a couple of weeks. I was looking at them and there wasn't a color combo my wife liked. The salesman said that was ok because just turn around. I laughed but when I did there was a truck pulling up with 3 tellurides on it. One which i bought. So this was a brand new shipment so maybe they have done something different since yours was purchased. If that is the case then surely they can do something to fix yours. I know the back seat sensor is on because it warned me when I was a little slow to get my dog out of the back seat. Maybe turning that off if you can to see if it makes a difference. I know you like it as is but maybe a try just to see.
Oh yea. Last Suburban we had was a 2010 I believe and it was an LTZ. The last vehicle we had was a 2015 Traverse LTZ. Been a Chevy guy most of my life. I was told by a couple of people that not only owned Traverses and Acadias but also worked on them at dealers that those things were 100,000 mile vehicles. I believe them now! 101,000 and am having transmission issues just like they said I would. Bought me a new 2017 2500 duramax and I can say it is not near the vehicle my 2001 with the 8.1 liter gas motor was. After those two I figured it was time to try something else. Wife won't drive a Ford no matter how good or bad it is. She liked the Telluride but just didn't like the interior until she saw the brown interior. It was sold after that!
I wanted to see how our rear seat ac worked last night so I tried a couple of things. First thing I did was remote started it, unlocked the front drivers side door and placed my hand near the back seat vent. It was on and cold so it didn't just start blowing when I opened the door or moved my hand next to the vent. Second thing I tried was to sit in the car and start it while sitting in the front seat. I turned the vent around toward me before starting to make sure I could easily feel it come on and it did. This was with it set to on the previous time I started it. I also tried turning it off the previous time it was running and followed the same procedures. Still with nobody in the back seat. I would have to manually turn it on when starting it again. I also do know the 2001 suburban worked this way too. My brother-in-law still has our old 2001 and i got him to try it. He said it works exactly as I described the my Telluride does. That is an LT version suburban. I thought our 2010 model suburban was an LTZ but it was an LT 2. The Traverse is an LTZ. All work as our Telluride does. Maybe that is just what I am used to and guess never thought to check if the Telluride worked any different. I guess I was lucky with ours that it is the same as other SUVs I have owned. My wife would have been pretty POed if it didn't.
Thanks for testing those things out. Yours and mine are obviously operating differently. I hope mine doesn't change if/when the my version of the vehicle's software is updated. I'm at around 5,500 miles now so will be getting the first oil change soon. Not sure if updating the infotainment software is part of that first service. Like I said, I'm happy my Telluride's AC works like it currently does and I don't have to shut off rear AC every time I start the vehicle when no one is sitting back there (since there usually isn't). Thanks again.

Thank you too! I learn something every day and these forums help tremendously. Kind of scary when something is operating like you want it to and then a simple oil change might result in messing that up. I hope they don't mess yours up! Thanks for your time with this.
I am having a similar problem but with the front A/C. When I turn off the ac and turn the knob to the heat or the defroster the ac light turns back on. It is so annoying when you are using remote start to warm up your car or to defrost the windows.
On page 4-152 of the user manual "3.Select the (floor and defrost) or (defrost) position. The outside (fresh) air and air conditioning will be selected automatically." and on 4-153 "To reduce the possibility of fogging up the inside of the windshield, the air intake or air conditioning is controlled automatically according to certain condition."
In other words, Kia's defrosting/defogging logic automatically activates the air conditioning so that you avoid blowing humid air at the windshield, potentially preventing defrosting/defogging.
Hope this helps.

Just about all cars turn on the AC compressor when using the defroster.. If it's throwing wet hot air on the front windshield, it's going to take a lot longer to defrost the windshield, if it does it at all. Even my 71 Ford Torino turned it on when you hit the defroster.

This also happens with the heater. If I move the knob to a different postion it automatically sets to ac even if i have the heater on.

I have had my S for about 5 months now and have the same issue. The car resets every time I turn it off for more than 5 minutes to AC, 1 blue, 2 level fan. It is going to drive me nuts when I am auto starting my car in the winter!. Sounds like a definite bug.

Any new info on this? Dealer said they are looking into it but that was a month ago.
______________________________
I've now had mine at two separate dealerships for scheduled oil changes. Both have said the rear AC will automatically turn on to help the battery. They both feel that there may be a minor software glitch and a patch is forthcoming but nothing yet.
Well mine works well and as I like it to. I have an SX and the rear is set to always come on and synced to the temp the front seat is on. I always want the whole vehicle to warm or cool down. Like this morning it is 27° (that is kind of cold here in the south) and when starting the car if I only have the front of the vehicle warming it will take much longer to get it warm as apposed to the whole system working on it. Same in the summer when it is over 100° . Other vehicles I have had work the same way. My wife had a 2015 model other brand higher end model and it would sync the rear but would always set the rear temp warmer and the fan lower in the summer when synced. The rear would never get cool unless you turned off sync and set fan speed and temp to the desired setting. And yes AC was checked to make sure it was working properly. When warming in winter it worked much better when synced. Strange on the philosophies used in each brand to achieve interior comfort.
I’ve been reading some of the recent posts here and I’m a bit confused as to what we *should* expect With rear climate control.
In my EX, I have to manually turn on rear ac or heat after every restart, unless the car has only been off for a few minutes, in which case it seems to remember the last setting.
What doesn’t make sense to me is that when I do turn the rear ac/heat on, I always select “auto,” so temps are the same front and back. But it seems counterproductive to set “auto” manually every single time! Shouldn’t “auto” mean AUTOMATIC, meaning I shouldn’t have to mess with it unless I want the rear Climate off Altogether?
On another climate control note, in previous cars with automatic climate control, if I set the temp to, say, 75, on a cold day, the air wouldn’t start blowing cold air. It would wait until the system warmed up the air enough to start blowing warm air. Not so in my Telluride: it starts blowing cool air immediately.
Does anyone know, are both issues I’m experiencing considered bugs?
