Check on the clip/o-ring connections to the heater core at the firewall. Mine went from zero to PITA a bit faster than you describe though.Had to add more coolant - the nastygram light came on. This happens about once a year maybe. There’s a very slow leak that isn’t easily found and all of the hoses and water pump and things have been changed.
I can drive with the warning light on for a long time and she still won’t overheat, so I don’t worry about it any more than making sure to fill her up the next chance I get.
This could easily be avoided if I checked more often. DOH!
cheers,
