I don't have the third row child seats. I'm just talking about the regular backseat. I'm a bit surprised by the small amount of heat that comes out of the vents for the backseat passengers. There's plenty of heat for the front of the cabin. In addition to the vents on the back of the center console, there's vents underneath the front seats that direct air towards the back. I've tried different fan speeds and tried the three different vent position settings. I would have thought more seriously about getting the heated rear seats if I had known about this issue. Maybe there is something wrong with my car. It's less than a month old. Has anyone else had a problem with the back of their car not getting warm enough? It's been in the low 30s lately.
