My 21 CLA45 with 6800 miles keeps telling me to check coolant level but when I look at the reservoir, it looks pretty full to me. I included a pic below. The mercedes me connect app also tells me the level is OK but the car keeps warning me that I need to check the level. Has anyone experienced this?

MY20 CLA45 has been in and out of the dealer due to “cannot replicate the problem” but the coolant level is noticeably going lower. My SA mentioned that its “normal” for this model. How is this normal? No new car can possibly consume this much coolant, the difficult part is there are no leaks and pressures in the coolant system is good per dealer.
currently running out of ideas….

funny you mentioned this, you literally have to fight your case every time you address issues in regards to warranty work which can get very frustrating.

I had the same issue and brought it to the dealer. They topped it off and it hasn't happened again. The tech said monitor it, if it continues most likely a sensor issue.

how long ago did you topped it off? I did the same thing the first time, but came back a few thousand miles later then topped it off a couple times after

hi this happened to me with my 2022 cla 45s under the first 1000 miles. Happpened everytime the car had its cold start. Would appear on the dash to top up then disappears 15 secs later or something. Brought bottles of coolant from merc, constantly seeking technical help from them etc and found out it slightly below the limit in both coolant tanks. Top up the one stated in the picture by like 2-3 spoonfalls (dw about diluting) and top the hidden one up under the engine cover (unclip the cover) and fill that one up slightly. Also the coolant tank you showed in the pic make sure the sensor connection is fully in so just try that too. Don’t top up the coolant whilst it’s hot ofc haha. Gutted it Happened to me on my brand new car but now I haven’t got the sign back since!
