The temperature display on my 2021 Palisade Calligraphy doesn’t read correctly. It started doing this last summer before the warranty expired. It would read and work correctly for about 50 miles and then I would have to turn it down to about 68 to make the air temperature at 72, then set it at 80 for the heat to be 72. I carried it to the dealership and they said they couldn’t replicate the problem without driving it that far and couldn’t fix it. I’m living with it, but don’t like it. Reminds me of the old manual knob adjustment from days gone by. Any suggestions on how to fix this?
