Hi. Unless you are having to repeatedly refill the coolant system - which indicates a different problem, the false "low coolant" issue may simply be a failed sensor in the coolant recovery tank. It is not recognizing that there is adequate fluid in the tank. The scenario you describe where the car will not start after being driven, then parked suggests a "heat-soak" issue for an electrical component (crank/cam position sensor, starter solenoid, neutral safety switch, etc.). If you would like to have this looked at, a certified technician from YourMechanic can diagnose the starting issue and follow through with repairs.
