Warranty advice needed(coolant issue)

2017 2500LTZ 37,300 miles

You all might have read the threads concerning the " low coolant message". Well, I had into the dealer twice while still under warranty. Looking back into my receipts, It looks like they have gone through the steps necessary to try and trouble shoot the problem short of taking out an injector. Coolant has gone down to where the message has appeared again in the DIC. No coolant on the ground and it is a very slow issue. They looked into this issue about 10,000 miles ago and I know for a fact that these engines simply just don't burn/use this much.

I have never had a problem persist like this and not be fixed. When I talked to the service advisor he stated something about a diagnostic fee because it just depends what the issue is. Well, as you can imagine this has put me on the defensive.

Any advice on this would be greatly appreciated.

Thank you
