Getting cold air even when set temp very high and hot air when set cool.
- Yes, car was driven for a long time and definitely warmed up:

Noticed cold in the car, pulled over and increased temp one degree at a time, and got all the way to 89 Degrees and still Cold Air coming out.
When bumped up once more, the display changes to "HI" and the heat finally kicked in.
Drop down one degree back to 89 and cold air again?

Noticed the opposite happening as well.
Set temp is 69 degrees and very hot in the car, keep lowing down to 60 and still get very hot air.

Temp Sensor issue? CUE issue?

I don't know for sure but there have been two upgrades to CUE related to the HVAC system since I bought mine in October. I've had one update and I'm due for the second one. Have your dealer check for updates, and be mindful that not all dealers are aware of the next round of updates. There is a thread about that on here.

just curious is there firmware update for non-CUE vehicles?
