I recently noticed the speed limit indicator is not accurate. On highways posted at 60 mph, the indicator shows the limit to be 55 mph. These are on several different highways that I have traveled for years. It has always showed 60 mph in the past. I checked for software updates but there were none. Has anyone else experienced this? Any suggestions? Thanks

I just had my gas tank drained while parked overnight in my driveway. The security camera did not pick anything up as gas filler was on opposite side. What locking gas cap is recommended for my 2019 Sierra 1500? Thanks for your help.

How do you change the interior lights so they come on when you enter or exit the truck?
