Yes, even after driving a while. It is ALWAYS too high. I put a battery powered wired thermometer inside that is pretty accurate but looks stupid. I'll be selling soon and would like to see if there is another fix to try.

The outside thermometer in our 2020 Sierra 3500 is way off. Consistently reads 8-10 degrees too warm, winter or summer, rain or shine. I replaced the sensor that is in the passenger side mirror but it made no difference. Dealer looked and agrees there is a problem but did not know how to fix. Anyone have any ideas?
