Checked the coolant level in the overflow tank, and level was between the two marks.

The diagnostic lights were the red triangle on the dashboard with the exclamation, and the coolant thermometer icon shown on the console.

T​hanks for posting, when the engine overheats it will trigger the master warning light, it sounds like the gas engine water pump is leaking, it's not unusual on these engines at higher mileage, replace the thermostat at the same time and use the super long life pink coolant as the factory specifies for hybrids.
