Drove it for about 3 miles at about 30 mph. Will take further tomorrow and see what happens.

Replaced the battery in a 2016 Sierra and the temp guage on the dash is reading 32 degrees outside when it is 90 degrees. Switched from english to metric and it went to 0. Switched back and still 32. How can it be corrected. Was working fine before the battery exchange.
