Re: jeep commander temperature sensor
I just made a post about this same issue in the Cherokee forum. My 2009 GC did the same thing last week. It was like 41 in the morning and read that all day even when it was up in the 60's. The update was the recommended fix. I have not tried it yet as it appears after a hour long drive, it started back to its normal operation of reading the right temperature.
