The dispatcher says the victim is in critical condition in the emergency room at Northridge Hospital Medical Center ... and there are friends standing by waiting for updates in the family room.

Cops say witnesses claim they saw two male suspects approach a parked car on Bryant Street in Northridge and open fire. The suspects remain at large ... in the dispatch audio, they are described as 2 male Hispanics, 15-20 years old, wearing gray hoodies. The dispatcher also says police found some 9mm bullets on the ground near where the car was parked.

Maria's family tells TMZ ... Maria was in the car with two friends, a male and a female, when two males approached and started shooting at the car from the driver's side.

We're told Maria was sitting in the passenger seat when she was shot ... and the other two people in the car were NOT struck by bullets.
