Strange Error Message on the Dash
I sent the dealer a message and they didn't know.
I have only had it appear a few times and every time when the car was stationary. I would drive along, park, leave the car running (sometimes the engine would stop as I had stop start turned on). After a few mins it would come on. Car has just been serviced and coolant temp is normal (slightly below normal actually).
Doesn't happen very often. Only twice in the last week. Outside temp is cool 12.5c
Any ideas?

I wonder what changed.
I don't think it is the transmission oil temperature? Based on the one above (same icon, but with text), it said "The coolant is too hot" which kind of point to the engine temperature? But I could be wrong.
