Low coolant message. Any more ideas??

All,

2017 2500 LTZ with just over 36,000. Had in the shop at 16,000 roughly for the message. Circuit was not opening right and they changed out tank and re-filled. 26,000 roughly, noticed coolant was down. They did a pressure test and added, but not could not find any leaks.

I looked at the tank after I got the message again the other day. Sure enough, the tank has gone down. There is nothing underneath and it is absent of any coolant smell. There is no way it went down that much in 7000 miles without it leaking somewhere right? Very slow at that.

first off, glad it is still under warranty on the engine/ powertrain.
Going to call dealer tomorrow.

Does anyone have any other ideas on this?

Check the EGR coolant pipe. I had the same issue back when I first got my truck. Dealer couldnít find the leak till they had to remove that pipe to replace an injector, then found it. Itís a slow enough leak that the coolant evaporates before it hits the ground, but makes a mess on top of your injector and valve cover. There was a TSB about this.
