2014 GL 450
Coolant Leak
Got into the truck this afternoon and had a "check coolant" message
. Thought it was odd as we just purchased the 2014 CPO GL 450 which was serviced for the 30,000 mile service early ( truck has 29,500 miles). Did some research and people said it was common that the sensor was pretty sensitive. Well the misses leaves to go out with her friends, and I go into the garage and notice that there coolant all over the ground
. Of course I told her to come home and when I lifted the hood it was squirting out of some canister, and there was little to no coolant left. Waiting on tow service now!!!!Ill keep everyone posted on the problem

My problem was not as severe as yours. I had coolant leak but a very slow leak. Eventually, enough to see a puddle in my driveway. They changed out the hoses and connectors for me.

2014 GL 450
Just an update the dealership contacted me and fixed the problem. Apparently the pipe leading to the turbo cracked and had to be replaced.
I haven't picked the vehicle up do to them replacing the driver side seat back cargo pocket which was ripped (covered under warranty).

My 13 Gl450 had the same issue, I was about to go on a road trip about 800miles out and after breakfast near home , top up coolant message came on. Lucky me I had the coolant in my garage top a whole bottle in and drove to the dealership. At the dealership the whole floor had coolant.
cause: left turbo coolant return pipe failed.
it is very surprising, from no indication to a total failure. I work on my w163 and other cars and usually when coolant leak I will have some sort of minor leak which I can tell before it fail.

same thing just happened to me. saw a ton of green liquid all over the garage floor. yellow warning light was on. cut up an old pair of jeans, took a long time to clean it up.
took it to service and they said the same thing -- turbo pipe. i only have 26,000 on the odo and the car is 51 months old. they are covering under goodwill, otherwise it's $950. seems like a pretty common problem on the GL based on this thread.

Seems like the turbo pipe is such a common issue, it's surprising that the bill is 950 . Change a hose and top off coolant . but anyway I think I have to look into a good aftermarket hose since this fail easily. I only had 14,000 on the clock
