It happened around 2:15 Sunday morning at the Autumn Ridge Apartments on the 1500 block of Little Gloucester Road.
At least four vehicles were found ablaze near building "C."
Fire crews worked for about 20 minutes to extinguish the flames.
An investigation has so far revealed that a fire may have started in a car by another building and then spread to the vehicles nearby.
Heavy damage was reported on three of the cars and minor damage to the fourth.
Authorities continue to investigate and have not said whether the fires are 'suspicious.'
