BRAND NEW 2012 PRIUS DRIVING OUT OF THE DEALERSHIP AT NIGHT, NOTICED A RATHER BOTHERSOME TRAIT: LIGHTS VIEWED THROUGH THE WINDSHIELD HAVE A PRISM EFFECT WHERE THERE IS A "GHOST" IMAGE LOCATED ABOVE AND BELOW THE ACTUAL LIGHT SOURCE. I WANTED TO KNOW IF THIS WAS DEFECTIVE WINDSHIELD, OR JUST HOW THE PRIUS IS DUE TO THE VERY LOW ANGLE OF THE WINDSHIELD. IT IS DEFINITELY A PRISM TYPE EFFECT AS IT DIFFERS BY COLOR, AND AS YOU APPROACH THE LIGHT SOURCE, THE GHOST IMAGES MERGE INTO THE SINGLE IMAGE. THIS HAPPENS WITH ALL LIGHT SOURCES, THE SUN (WORST OF ALL), HEADLIGHTS, TAIL LIGHTS,STREET LIGHTS, TRAFFIC LIGHTS, ETC. WHEN DRIVING AT NIGHT THIS GHOSTING OF THE LIGHT SOURCES IS REALLY DISTRACTING AND MAKES IT LOOK LIKE YOU ARE LOOKING AT A BLURRED IMAGE. NOTHING IS CRISP OR CLEAR. IT'S BAD ENOUGH THAT MY WIFE AND I ARE NOT DRIVING THE CAR AT NIGHT AND USING ANOTHER VEHICLE. WE HAVE HAD OTHERS IN THE CAR TO CONFIRM THE ISSUE.

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

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

14V053000 · Electrical System:software; Hybrid Propulsion System: Inverter

Feb 12, 2014

Toyota is recalling certain model year 2010 through 2014 Prius vehicles. In the affected vehicles, the Intelligent Power Module (IPM) inside the inverter module (a component of the hybrid system) contains transistors that may become damaged from high operating temperatures. If this occurs, various warning lamps will be illuminated on the instrument panel and the vehicle will have reduced power allowing it to only drive a short distance.

Consequence & remedy

Consequence: The vehicle may enter a fail-safe/limp-home mode that limits the drivability of the vehicle. The hybrid system could also shut down completely resulting in a vehicle stall, increasing the risk of a crash.

Remedy: Toyota will notify owners and dealers will update the software for both the motor/generator control electronic control unit (ECU) and the hybrid control ECU, free of charge. If an owner experiences a failure of the inverter before the vehicle receives updated software, the dealer will repair or replace the inverter assembly with a new one at no charge. The recall began on March 21, 2014. Owners may contact Toyota at 1-800-331-4331.

Consequence & remedy

Consequence: An inaccurate label could lead to owners overloading their vehicles and tires. An overloaded vehicle can result in a tire failure which may result in a vehicle crash, personal injury, or property damage.

Remedy: Southeast Toyota will notify owners and provide a corrected label with instructions concerning its installation. A small group of the affected vehicles will need additonal remedies which are still being developed. The recall began on May 28, 2013. Owners may contact Southeast Toyota at 1-800-301-6859.

During modification by SET to include accessories such as leather seat covers, seat heaters or headrest DVD systems, these vehicles may not have had the passenger seat occupant sensing system calibration tested. Without passing the calibration test, the occupant sensing system may not operate as designed.

Consequence & remedy

Consequence: If the front passenger seat occupant sensing system is out of calibration, the front passenger airbags may not deploy or they may deploy inappropriately for the passenger's size and position. This could increase the risk of personal injury during the event of a vehicle crash necessitating airbag deployment.

Remedy: Southeast Toyota will notify owners, and dealers will test the sensitivity of the occupant detection sensors, and recalibrate them as necessary. The recall began on March 21, 2013. Owners may contact Southeast Toyota at 1-800-301-6859.

On September 19, 2019, the Office of Defects Investigation (ODI) received a defect petition from Mr. Roger Hogan requesting that the Agency investigate and recall certain Toyota Prius, Prius PHV, Camry Hybrid and Avalon Hybrid vehicles for a brake actuator valve wear condition covered under Toyota Customer Support Programs ZJB and ZKK (subject CSP?s). In support of his request, the petitioner identified 117 NHTSA complaints allegedly related to the subject CSP condition, including 60 reporting crashes. On September 30, 2019, ODI opened Defect Petition DP19-004 to evaluate the petitioner?s request for an investigation. In August 2020, the petitioner notified the Agency that he was withdrawing his petition. Because the petitioner has withdrawn the petition, we are denying the petition as moot and no further analysis of this petition is necessary.NHTSA is authorized to issue an order requiring notification and remedy of a defect if the Agency?s investigation shows a defect in the design, construction, or performance of a motor vehicle that presents an unreasonable risk to safety. 49 U.S.C. ?? 30102(a)(9), 30118. Because the petitioner has with withdrawn the petition, the petition is denied as moot. This action does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency notes that it is not required to receive a defect petition prior to opening a defect investigation and will take further action if warranted by future circumstances.
