I got the same message for about a week straight. Took to dealer to top off and they pressure tested the coolant system twice. No issues since. Car has just over 100k on the clock with stock coolant system. Just FYI.

Ok thanks. Well my dumb*** did pull the dipstick while the engine was running and the engine didn't like it. I thought I'd get a better look at the oil on the dipstick while it was sloshing it around to verify any coolant. Pretty sure the engine thought something bad happened and may have thrown the code that way.
