IllustrationTHE LINING ON THE DEFLECTOR RUBBER GASKET/SEAL OF THE SUNROOF HAS BEEN DETERIORATING. I HAVE HEARD FROM MANY OTHER PRIUS III OWNERS THAT THIS IS A COMMON DEFECT FOR THE 2010-2013 YEAR MODELS. I BELIEVE IT IF IS THIS COMMON, TOYOTA SHOULD BE RESPONSIBLE FOR REPLACING IT.

422 reportsI SWITCHED INTO NEUTRAL AND PUSHED THE PARK BUTTON TO PARK. I LEANED FORWARD TO GRAB MY WALLET AND FELT THE CAR ACCELERATING OVER THE PARKING CURB. I IMMEDIATELY SLAMMED THE BRAKES AND THE CAR ACCELERATED INTO A BUILDING. I AM FORTUNATE TO BE ALIVE BECAUSE IF THE AIRBAG WOULD HAVE ACTIVATED, I WOULD HAVE BROKE MY NECK.
VEHICLE WAS IN MOTION TRAVELING ABOUT 50 MPH WHEN AN EFFORT WAS MADE TO PASS ANOTHER VEHICLE ON A 2 LANE ROAD, THE VEHICLE LOST POWER WHILE WE WERE PASSING, WE BARELY GOT BACK INTO OUR LANE AND JUST BARELY AVOIDED A HEAD ON COLLISION. THEN THE VEHICLE SLOWED TO ABOUT 15 MPH AND LIMPED TO A STOP A MILE LATER. WE COULD HAVE DIED.
THE PROBLEM STARTED WITH A CHIRPING NOISE WHEN THE BRAKE PEDAL IS DEPRESSED. TODAY THE CAR APPEARS TO LOSE REGENERATIVE BRAKING CHARGING. THE VEHICLE STABILITY CONTROL AND ABS LIGHT AND BRAKE LIGHT CAME ON. THE BRAKE APPEARED TO BE MUSHIED.
I REPLACED MY BRAKE BOOSTER THREE TIMES IN TWO MONTHS.STILL I HAVE BIG ISSUES WITH TOYATA COMPANY.
MORE THAN ONCE I WAS DRIVING ABOUT 40/45MPH, ONCE ON A CURVE, ANYHOW AS I WAS GOING THROUGH THE CURVE IT FELT AS THOUGH THE BRAKES ENGAGED, WITHOUT ME TOUCHING THEM. I UNDERSTAND THE SAFETY THING, HOWEVER AT BOTH INSTANCES IT WAS NOT NECESSARY. IT CAUSED THE CAR TO PULL TO THE LEFT. ALMOST CAUSING ME TO LOOSE CONTROL.
HEAD GASKET 77,000 MILES WITH THE HEAD GASKET ISSUE THE CAR ENGINE WAS SHAKING WHEN IT'S WARMING UP. THE CAR LOG SHOWED MISFIRES IN 1ST AND 4TH CYLINDERS.

VEHICLE IS MANUFACTURED WITHOUT ANY REGARD FOR PREVENTING MICE FROM ENTERING THE PASSENGER INTERIOR--- AIR INTAKE VENT UNDER WINDSHIELD AND 2 REAR DECOMPRESSION VENTS LOCATED IN THE REAR CARGO COMPARTMENT ABOVE THE WHEEL WELLS ARE OPEN TO THE EXTERIOR ALLOWING UNIMPEDED ACCESS TO THE INTERIOR OF THE CAR. HAD MICE IN THIS CAR 2 WEEKS AFTER PURCHASE IN 2012 AND HAVE BEEN DEALING WITH THIS PROBLEM FOR 7 YEARS. JUST RECENTLY, HAD TOYOTA INSTALL 1/4" HARDWARE CLOTH OVER THESE 3 AREAS AND THIS SHOULD HELP SIGNIFICANTLY TO PREVENT ENTRY. ALL PREVENTATIVE MEASURES TO PREVENT MICE ENTRY HAVE BEEN DILIGENTLY TAKEN BY ME, WITHOUT SUCCESS. MICE CAN MAKE A PERSON VERY SICK. THEIR EXCREMENT CARRIES HANTAVIRUS..... AND THE MICE CARRY TICKS, WHICH CAN LEAD TO LYME DISEASE. SIMPLY MANUFACTURING THE CAR WITH THESE VENTS PROPERLY SCREENED WOULD GREATLY REDUCE THE CHANCE OF OCCUPANTS CONTRACTING A SERIOUS DISEASE.THE MICE ALSO DO A LOT OF DAMAGE TO THE CAR ITSELF, IN MY CAR THE DRIVER SEAT BELT WAS CHEWED, AND I HAVE HAD TO REPLACE THE CABIN AIR FILTER SEVERAL TIMES BECAUSE OF NESTING IN THIS COMPARTMENT(AFTER HAVING BEEN UNKNOWINGLY BREATHING THE MICE EXCREMENT AS THE AIR PASSES THROUGH THIS FILTER ON ITS' WAY TO THE INTERIOR. TOYOTA NEEDS TO BE PRESSURED BY YOUR AGENCY TO CORRECT THIS VERY SERIOUS HEALTH HAZARD THAT THEIR CAR IS PRESENTING. THEIR IS NO LEGITIMATE REASON FOR THIS SITUATION TO EXIST. THE COST TO TOYOTA WOULD BE NEGLIGIBLE.THE BENEFIT TO ALL PRIUS OWNERS WOULD BE VERY SIGNIFICANT, LIKELY PREVENTING MANY CASES OF DISEASE. PLEASE TAKE THIS SITUATION VERY SERIOUSLY, AS IS THE CASE. I ALSO WILL BE CALLING YOU TO DISCUSS THIS OVER THE PHONE. THANK YOU FOR YOUR HELP TO CORRECT THIS PROBLEM!

I STARTED MY CAR AND MY DASH LIGHTS FOR BRAKES, ANTI-LOCK, ANTI-SKID CAME ON AND BRAKES BECAME SPONGY. THIS HAPPENS INTERMITTENTLY. I PARKED THE CAR AND LATER CHECKED THE LIGHTS AND THE CAR WAS OPERATING NORMAL. I DROVE THE CAR AROUND THE NEIGHBORHOOD TO TRY TO DUPLICATE THE ISSUE. COULD NOT DUPLICATE. THE NEXT DAY I STARTED THE CAR THE LIGHTS CAME ON AGAIN AND BRAKES WERE NOT OPERATING NORMALLY. SPONGY AND NO ANTI-LOCK. I CHECKED RECALLS AND FOUND THE ISSUE WAS RECALLED IN 2010. I ALSO FOUND NUMEROUS COMPLAINTS ON PRIUS FORUMS FOR THIS ISSUE COVERING 2012 PRIUS. I THINK THIS IS A SAFETY ISSUE TOYOTA SHOULD RECALL FOR 2012 AS WELL.

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.

Jan 16, 2013
Southeast Toyota Distributors, LLC (SET) is recalling certain models interspersed through model years 2009 through 2013 as follows: model year 2009-2012 Tacoma, 4Runner, Camry, Camry Hybrid, Prius, and RAV4; model year 2009-2010 Avalon, FJ Cruiser, and Highlander Hybrid; model year 2010-2013 model year Corolla, Sienna and Tundra; model year 2009-2013 Highlander and Venza; model year 2012 Prius V; and model year 2010-2012 Sequoia. 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.

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

Status: closed (inferred from source dates) · Service Brakes, Hydraulic:power Assist
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.
