Low Coolant message issue in 2017 Silverado HD Duramax

[jeez]

I've seen several posts about low coolant messages on new 2500 HD Duramax engines. My new Silverado had this issue. At about 1500 miles, message came on and the dealership filled the reservoir and bled the system. Message came on again about 3,000 miles, so it went back to the dealership. The dealer pressurized the system over the weekend and then ran the system until hot. Turns out the lower radiator hose had a small defect. This hose apparently has several hoses that are attached to it. Technician said he hoped to never have to work on one again, lol. Wanted to share with you so that if you have this issue, have the dealer check the lower radiator hose system for defects. Other than that, this truck is awesome.

There is also a TSB about this now, the initial ones were not filled properly.

I read that TSB, just wanted to share that mine was a defective hose and not one of the initial ones.

Thank you for sharing. Suggest sharing over on duramaxforum.com as well if you have not already, might be helpful to the Diesel boys (and girls) over there

Thanks for the suggestion, Colossus. Shared with them this morning.

My water pump is being replaced now. Dropped it off this morning because the last 3 mornings I've had coolant on my driveway. Truck has 21k on it.

I just got the message this morning when I started the truck. It also showed the traction control light. It went away after a minute. I turned the truck off a few minutes later and neither came back on when I started again.
