Twice now we have parked the car leaving the rear windows down 2 -3" for ventilation only to return to the car with the horn blaring and 4 ways flashing. Doesn't happen with all the windows up tight. Any other's had this issue?

It has a rear seat motion sensor. Leaving the windows down probably triggers something.

It is intended as a safety feature so you don’t leave a child or pet in the rear seat. There is a way to turn it off in the settings.

Thanks for the assist. Yes we turned off the rear safety alert and that has silenced the horn. Not really understanding why the rear seat alarm only works if a window is left partially down. I mean can't one just as easily forget that there's a kid or pet in the back seat with the windows all the way up???

Yes, you should get the reminder when the windows are up if there is a child or pet in the back seat.

Not what I'm saying. My question is why does the horn blow only when a window or the sunroof is left slightly open when the rear seat alarm is set and the vehicle detects movement? If the windows are fully closed and the back seat alarm is set, the horn will not blow.

Again, possibly the open windows are causing the sensor to think something has been left in the back seat. If the windows are closed, motion from the wind would not enter the vehicle making the sensor activate the alarm.

Maybe items or people outside the car are triggering the rear occupancy sensor if the windows are down? The manual. I think explicitly says this may occur and definitely mentions wind and bugs setting it off

yep. pg 3-22 of the owners manual:

System precautions
• Make sure that all the windows are
closed. If the window is open, the
alert may operate by the sensor
detecting an unintended movement
(e.g. wind or bugs).

This is a question, and Not about a limited, which seems every advertisment is about online and the web. I have a SEL 2022 with convenice and premier pkgs, which are nothing in comparison to the limited, okay, got that. Now, answer me this, Hyundai cannot, 'How do I turn ON the alarm in this car?' Hyundai said' push lock on fob twice, I did, and it didn't set anything, it locked the doors. Thanks, appreciated.
