That means the coolant is not flowing out from the thermostat. Sounds like a bad thermostat. Take it out an test it in a pan of water with a thermometer. Should open at 195°.

When you say "overheating" is it actually hot ..... or are you getting a message on the IP or if the car has a temp gage is it showing hot. It could be just a bad sending unit.
