NHTSA Complaint #10703753 — 2014 TOYOTA CAMRY

I WENT OUT TO THE GARAGE TO VERIFY THAT THE GARAGE DOOR WAS CLOSED AND HEARD SOMETHING HUMMING IN THE GARAGE. UPON INVESTIGATING THE SOUND IT TURNED OUT TO BE COMING FROM UNDER THE REAR OF THE CAR. THE ONLY THING THAT MADE SENSE TO ME WAS THE FUEL PUMP WAS RUNNING. I PROCEEDED TO GET THE KEYS AND CYCLED THE IGNITION TO ON WITHOUT STARTING THE CAR AND THEN BACK TO OFF. THE HUMMING STOPPED. I DID REMEMBER HEARING A SECOND HUMMING SOUND START AND STOP WHEN TURNING THE KEY TO THE ON POSITION, WHICH WOULD BE THE NORMAL FUEL PUMP CYCLING FOR AN ENGINE START SEQUENCE. I AM WONDERING IF WHAT I ORIGINALLY HEARD MAY HAVE BEEN A RELIEF VALVE SLOWLY BLEEDING OFF PRESSURE, BUT I AM NOT SURE IF THERE IS A RELIEF VALVE SOMEWHERE IN THE BACK OF THE CAR. I DISCONNECTED THE BATTERY OVERNIGHT FOR PIECE OF MIND. THIS DID ALL OCCUR BETWEEN 4-5 HOURS AFTER THE CAR HAD BEEN PARKED. I WILL BE CONTACTING MY TOYOTA DEALER REGARDING THIS PROBLEM. *TR
