NHTSA Complaint #10481010 — 2012 TOYOTA PRIUS

VEHICLE IS PARKED OUTSIDE, AND DURING MORNING COLD START, THE VEHICLE PRODUCES A MOANING/WOOING SOUND FOR APPROX. 50-75 YARDS WITH VEHICLE MOVING UNDER 25 MPH. THE SOUND IS BEING GENERATED FROM THE FRONT WHEEL WELLS. SOUND GENERATED IS RELATED TO VEHICLE SPEED. THE FASTER THE VEHICLE MOVES, THE MORE FREQUENT THE SOUND BEING PRODUCED DURING THE FIRST 50-75 YARDS. STRANGE SOUND IS GONE AFTER THAT, AND DOES NOT RETURN UNTIL THE NEXT COOL/COLD START. OWNER TOOK THE VEHICLE BACK TO DEALERSHIP FOR INSPECTION, AND DEALER TOOK OFF THE FRONT WHEEL TO INSPECT BRAKES, WHEELS, AND TIRES, AND WAS NOT ABLE TO LOCATE OR REPRODUCE THE PROBLEM. ABNORMAL SOUND IS ONLY PRODUCED DURING MORNING COLD STARTS AND WHEN VEHICLE IS LEFT TO COOL(I.E. PARKING LOT AT WORK). *TR
