Works well on my ‘23 CX 5 once the coolant gets up to temp. The automatic setting might run the fan a little too strongly as the car engine comes up to temperature. I have an attached garage which may be 15 degrees warmer than outside temps. So I got in the car today and the outdoor temp sensor showed 54. Outdoor air temperature is 42. So as I left the house the fan is running a little too fast and actually is cooling the car down. Once the out door temp sensor cools down I’ll notice the fan will decrease and eventually ramp up as coolant temperatures hit around 130 F or so. Like most cars I have driven in cold weather, the heating system starts the vents in the defrost position until the engine warms. As engine temps go up it then goes to floor and dash vents, and with a little more driving it goes to floor. So feet heating in the auto position is a little shaky regarding fan speed and airflow outlets while the engine warms up.

In my area I wouldn’t touch a Kia or Hyundai for any price. It’s a theft magnet and even if it has the security updates, they are either still being stolen or broken into in an attempt to take them. Many insurers will not insure them and even if they do, they carry a premium cost due to the theft claims.
