A thick plume of black smoke was seen around Ellen Street in Wollongong after a car burst into flames in a carpark near the Kids Uni on Boxing Day.
Emergency services were called around 11am on Tuesday and found the vehicle well alight once on scene.
A NSW Fire and Rescue spokesman said no one was in the vehicle at the time of the incident and no one was hurt.
Two crews from the Wollongong Fire and Rescue unit attended and took firefighters around half an hour to extinguish the blaze.
It is unknown how the fire started at this stage.
