Coolant level

My coolant level slowly goes down and I continually have to add coolant for it to be at the proper level, is this normal? Over the time I have owned this truck(1 year and 6 months) I have used almost a entire gallon of coolant. Also would it be bad if I filled the overflow reservoir almost all the way to the top? Would it blow coolant out everywhere?

Funny, as I just had coolant level low come up on dash this a.m. it was damn near full but I added a cup or so. Hoping it was just an air bubble. I have no leaks or drips in my clean concrete driveway. Time will tell

Took mine to dealer for low coolant light. They advised improper filling from factory. They burped and topped system off.

No, not normal nor OK. Take it to dealer if under warranty.

What Ron said. A 2017 vehicle should still be under factory warranty, USE IT!!

I've got the same issue. When I purchased the truck a couple of months ago the shop put a pressure test on it and it held for 8 hours. SO I was thinking maybe water pump, not to sure about the WP but the engine only has about 30K on it so to early for a WP failure (could be the old WP on the new motor which was replaced under warranty) in my book so am watching it for now.

Mine has 34000 miles on it, so sounds like it's an issue.

Mine has been coming on for the last week. I don't tink this is normal, but my dealer says nothing is wrong. I also still have the surging issue, and they state nothing wrong. Even a small amount of coolnat loss is not normal, although I also have a 2014 Mercedes that does the same thing. So, with today's engines, is this the new normal? Topping off the fluid every so often?
