The two-alarm fire that burned an acre was reported at about 3:30 p.m. The Oakland Fire Department received multiple reports about the blaze from passers-by.
An abandoned vehicle sparked the brush fire, Oakland fire Battalion Chief Melinda Drayton said.
Almost five hours after it was reported, the owner of the vehicle returned to her car and talked to a fire investigator. She told the investigator her car overheated, so she parked it over dry grass, which caused the fire to start.
Someone picked her up and took her to Chabot Space & Science Center.
Firefighters monitored the area for several hours to make sure the fire restart, Drayton said.
In addition to the Oakland Fire Department, crews from Cal Fire and East Bay Regional Parks responded.
The woman's vehicle was destroyed, Drayton said.
No injuries were reported. The blaze was controlled at 4:30 p.m.
