Today was the first day that I have driven the NX under 40f. I was pleasantly surprised to find out that the seat heaters get hotter with colder outside temperatures. When I have tried them before I thought that they were not as hot as the BMW and RX heaters were.

I thought the seat heater had 3 settings. It wasn't as warm at similar settings when it wasn't as cold outside?
Yes the seats have 3 settings but there must be another setting that is controlled by the outside temperature. This morning in the 30s the seats were much hotter then they are now in the 50s. It will be interesting to see if the settings change more as it gets even colder.

Does it ever go into the negative where you live? That would be a great indicator.
Yes it does but not for another month or so.
Saturday night it made it down to 31f for the first time since last spring. We are expected to get into the mid 20s this week.

I wonder if the heater adjusts to its intensity in order to attain a certain temperature. For example, setting 1 is always a certain temperature for the seat, but when its really cold to begin with, the heater turns on higher to more quickly heat up the seat to the corresponding temperature.

The passenger seat is hotter then the Drivers seat most of the time but mine is getting hotter with use. My original assumptions may be wrong and the wires may just need to be burned in to achieve a hot setting. The seat is getting hotter the more that it is used. It still is not as hot as the passenger seat or the BMWs that I have had for the last 4 years.

^ This is the most probable explanation. can't really do a test unless you wait until summer again or you have a freak high temperature day.
