The cooling system is not holding pressure, replace the cooling system cap check that the coolant level is full.

If the radiator is full, and any cooling system work has been done before this started, likely all that’s needed is to ask your shop to bleed the air out of the cooling system. I had a similar thing symptom on my Corolla after I had to remove a heater hose to access another part, and some coolant leaked out. Bleeding the air out was the solution.
