I have the 2020 Silverado 2500 HD and just got back from a 3700 mile trip towing a ~7000lb travel trailer. I had to fill my 4.5 gallon DEF tank three times so I am getting way less than 1000 miles per gallon! It eats DEF like crazy. Mine starts giving me warnings that my DEF range is 975 miles about 150-200 miles after I fill it. I took it to the dealer when we returned and they said they did a software update related to DEF but I haven't driven enough yet to see if it changed anything.

Mine starts giving me warnings that my DEF range is 975 miles about 150-200 miles after I fill it. Also, about 20 miles from home the DEF gauge went from 3/8 to 0 in one step and told me "DEF low, speed limited soon". The DEF sensor is seriously goofed up and the 2020 is using a *lot* of DEF. They did the DEF related software update when I got back but I have not been towing to see if it still uses an exorbitant amount of DEF.

Anyone else having their infotainment system rebooting frequently? I have the 2020 Silverado 2500 HD High Country. It's fairly random unfortunately. Some days it will reboot 3 or 4 times, other days not at all. We just took a 600 mile trip after the dealer installed a small software update and it only rebooted once the entire trip. We brought it in to the dealer today for the larger software update, and it rebooted on the way home. Now we have to bring it back in so they can contact Chevrolet and see what they want to do about it. Just wondering if anyone else is having the same issue.
