Toyota Prius Service Brakes Safety Report | Apr 30, 2012
Reported on Apr 30, 2012
| THE VEHICLE EMITS A REPETITIVE 'WOO......WOO.....' THAT VARIES WITH SPEED/WHEEL REVOLUTION (SOMETHING RUBBING DURING EACH REVOLUTION). TO THE BEST OF MY ABILITY TO TELL, IT SOUNDS LIKE THE GROAN IS COMING FROM THE REAR-PASSENGER SIDE. THE SOUND IS USUALLY PRESENT AFTER THE CAR HAS SAT OVERNIGHT OR AFTER PROLONGED PARKING AND LAST FOR 100-300 FEET OF DRIVING. I'VE EVEN HEARD IT AFTER FOUR HOURS OF BEING PARKED AT WORK. IT WILL TYPICALLY MAKE THIS SOUND FOR A FEW DAYS AFTER A RAIN EVENT. THE SOUND HAS OCCURRED IN BOTH FORWARD AND REVERSE AND WITH THE EMERGENCY BRAKE ON OR OFF PRIOR TO DEPARTURE. I PURCHASED THE VEHICLE IN APRIL AND HAVE HEARD IT ALL THE WAY TO THE PRESENT. DURING A TIRE REPLACEMENT I MADE NOTE OF THE ISSUE TO THE DEALER, WHO ATTRIBUTED IT TO ROTOR OXIDATION. I RESPONDED THAT I'VE HEARD THE GRIND/GROAN OF RUST BEING WORN OFF THE ROTOR WHEN FIRST APPLY THE BRAKES, AND THIS IS NOT THAT SOUND. I WENT IN WITH A RECORDING ON MY PHONE AND THE TECHNICIAN AGREED IT WASN'T RUST. THEY REPAIRED THE TIRE AND TRIED TO REPRODUCE THE CONDITION WITHOUT SUCCESS. THEY DID TEAR DOWN THE BRAKE AND FOUND NOTHING OUT OF THE ORDINARY. THE FACT THAT THIS ISSUE PERSISTS ON MULTIPLE VEHICLES OF THIS MODEL IS INDICATIVE OF A MANUFACTURER'S DEFECT THAT SHOULD BE ADDRESSED. *TR | |
