EVERY ONCE IN AWHILE I GET A GGGRRR NOISE WHICH SEEMS TO COME FROM THE REAR OF THE CAR AND LASTS FOR ABOUT 1-2 SECONDS (NOT LONG ENOUGH OR FREQUENT ENOUGHT TO TRACK DOWN) WHEN IT HAPPENS THE CAR IS TURNED OFF AND I WAS WONDERING WHAT IT MAY BE....FUEL PUMP CYCLING, HATCH RETENSIONING OR WHAT. ANY IDEAS?

 

If you have just turned the car off within the last few minutes, it is most likely your gas tank "purging" via the vent canister next to the tank.
