It seems like early AM first start up the low coolant light comes on for a few seconds. Its happened a few times. The truck is a 2019 2500HD with 30,000 miles. I have a friend with a 2017 with 30,000 and its now doing the same thing. Dealer did a pressure test of the coolant system and found a head gasket issue. This is the 5th truck he has had with this issue in the last 2 months. They are going to replace the head gaskets? What if anything has been experience out there?

Mine did this twice on my 18. I took it in and they added more fluid. Apparently these are hard to burp and needed more fluid. Been over 15,000 since the last burp and no more error message.

Mine showed an error again a short time after I got my engine block heater recall done. It took about a half a quart to make it go back off.
