Has anyone else noticed the rear hvac will not retain its on/off state between car starts?

Turning it on is somewhat of a process(at least when trying to do it while driving), requiring the physical button to be pressed, and then to select the on-screen auto button(and lock if you have kids). It would be nice if it just remembered its last state, or if I could turn it on without needing more than one button presses.

I am a little surprised that you can't switch between rear and front with just the "auto" button on the left side. Sucks you have to use the screen to adjust the rear (unless i am doing something wrong).

My rear AC always starts in the off position and I need to turn it on every time. Its very annoying.. it retains the rear temperature panel lock setting but not the on/off. This has been the most annoying thing till date. Its a software setting so hopefully Hyundai can fix it via a software update. If anyone has a workaround please let me know

I don't have a Palisade (yet!...), so forgive me if I'm misunderstanding the issue, but... looking at the manual, it seems that if you press the "REAR" button on the front control panel, then it allows rear passengers to control the rear zone by using the controls located between the rear seats.

Reading that, I assume that if you don't let rear passengers control their own HVAC, that the rear zone automatically follows the settings selected by the front passengers on the front control panel.

So why are you guys having to reach behind the seats to control the system? I assume you don't have any rear passengers when this happens. Can't you simply press the "REAR" button on the front controls again (to take control of the rear zone again) and just have the rear cabin follow the same settings as the front zone?

Again, sorry if i'm missing something, since I don't actually own the vehicle.

The issue is that I don’t want to manually have to turn on the rear climate control when i get in the car. The rear zone is always turned off when i start my car and I have to turn it on. If i forget to, I have small kids who don’t know how to use the rear climate control and are hot while I am comfortable in the first row.

But that's kind of my point. If you disable the rear seat controls, the rear cabin should automatically follow the settings for the front cabin. So your kids won't be uncomfortable.

That’s what you would expect. I have disabled the rear seat controls and I have set it to sync with the front cabin temperature. However, the rear cabin ac/heat does not turn on until I do it manually after every restart (its off as opposed to sync).

I think you guys should contact your dealerships and escalate this issue. On new models like these, Hyundai is likely to take notice.

Yep, agreed. Pressing the rear button simply brings up the on-screen controls on the center infotainment display. From there you can set specific climate controls, set it to auto, or set it to lock to disable rear controls. If I select auto, I'd expect it to stay in auto/sync when I next get in the car, but it doesn't. It just turns off.

Out of curiosity, if you Lock it to disable rear controls, does it fix the issue? Just trying to think of something that would explain the logic behind their software...

No it doesn’t help. The lock setting persists through the restart but the rear climate control on/off/sync does not

Had my limited palisade for 2 weeks now and this was hands down the most annoying issue with the car. Definitely seemed to be a software bug.

Based on that thread, it sounds like Kia is doing something about this.

Have you guys contacted your dealerships yet? This is the only way it's going to get noticed and addressed.

Ok I don't know what we did or if Hyundai pushed an update but this is working for us now. I notice mine says "auto" rear. Maybe you have to have it in auto? I turned the car off and on a few times and it stuck.

It would only persist the last rear AC settings for a short period of time between start / stop cycles. If you start the car again after a few hours or longer, it'll always revert back to Rear AC off.

I haven't really had a chance to test this out over more than say three or four back to back drives, but it does seem like it'll remember the state of the rear controls if a rear passenger is in the car each time. The moment there is no rear passenger it turns back off. I actually think this behavior is fine, I like the idea of the rear hvac turning off when I've got no passengers in the back, but it would be nice if I could hit one physical button to turn it on, rather than having to hit a physical button, it change what's on my center display, and then have to press another(and not physical) button.
