Losing coolant somewhere in 2012 LML....

I'm losing about a half of a quart of coolant everyday in my truck. Its a 2012 LML crew cab 4wd. It started about a week ago. My display flashed low coolant level. I check it, it's down to the min mark. Fill it up to the max mark, and drive it. Next morning, same thing. Down to the min. I drive about 100 miles a day, sometimes more. My truck does sit and idle for 10-15min. at times. Nothing really out of the ordinary. It is not running hot. Where is my coolant going, and has anyone else had this problem? thanks.

And it's doing this everyday. Not losing more or less, same amount, every day. Top it off in the morning. The next morning, back down to the min mark. Every day.

Sounds like you found the problem. Trip to the dealer in the future.

Armalite,

I'm sorry you are having this issue. Your truck is a 2012 and if you have under 36,000 miles on it, your truck is covered under your bumper to bumper warranty. Have you taken your truck into the dealer for this leak yet?

Evan, GM Customer Service

You're not trying to keep coolant in both sides of the tank are you?

I noticed a couple of drops on my hose today, the lower hose attaching to the radiator or so it appeared. There should be a tsb on this if a lot of people are having issues. My fluid also has never appeared low and I haven't seen any spots on the driveway either.
