Check coolant levels message
Hey guys! I have noticed when I get in my car after it’s been sitting for a while when I start it I get a “check coolant levels message”. My coolant is full, does anyone have an idea why this is happening? I can post a pic next time It comes up. Thanks 🙏🏽

I've been having the same issue and last week dropped it off to the dealer MB Natick MA.
Got a call from my SA and he said they cant find any leaks, however noted crustiness around the bottom of the radiator. So off to get that replaced.

i was getting this message as well, when car sat for a couple days. But also smelled the coolant after it was parked. Took it in and there was hose and washer that was replaced by the overflow tank.

happened to me twice within the last 12 months and each time, in the next 48-72 hours, full blown leak ... 1st time service replaced the return line, 2nd time replaced both lines ...
