NHTSA Complaint #11306218 — 2007 CHEVROLET AVEO

I HAVE PROBLEMS WITH WHENEVER I GO TO PUT GAS IN MY CAR, SOME OF IT GOES ON THE GROUND. NOT ALL OF THE GAS GOES ON THE GROUND, BUT A LITTLE LESS THAN HALF OF WHAT I PURCHASED. MY HEADLIGHTS ARE SO DIM THAT I CAN'T HARDLY SEE WHEN I'M DRIVING AT NIGHT. ALSO, MY PASSENGER SIDE AIR BAG LIGHT IS CONSTANTLY ON? THERE'S ONE THERE AND NOTHING BIGAMY WRONG WITH IT THAT I CAN SEE. THE STEREO.....ONLY THE DRIVER SIDE FRONT SPEAKER WORKS, THE OTHER THREE DOESN'T WORK AT ALL....PLEASE LOOK INTO THESE FEW THINGS OR GIVE ME SOME SORT OF IDEA OF WHAT I CAN DO
