LEASED A 2010 TOYOTA PRIUS 3 MTHS AGO. RIGHT FROM THE START GIVES VERY LOW MILEAGE: 39-41MPG AND HAVE BEEN TRACKING IT BETWEEN EVERY FILL UP. ALWAYS FILLED UP 10 GALLONS AND RESET TRIP METER EVERY TIME. GIVES ONLY 390-410 MILES PER FILL UP. COMPLAINED TO THE DEALER SERVICE CENTER AT GREENTREE TOYOTA AND THEY SAY THAT NOTHING IS WRONG WITH THE CAR AND THE MILEAGE SHOULD IMPROVE AFTER 10,000MILES. RIGHT NOW THE CAR HAS OVER 5200MILES. FOR THE LAST 2 MTHS, I STARTED NOTICING THAT THE SPEEDOMETER IS READING HIGHER TOO. IF THE ROADSIDE RADAR SHOWS 35, THE PRIUS SPEEDOMETER SHOWS 37 AS THE SPEED. AN OVERAGE OF 2 MILES. SO, IF WHEN I HAVE DRIVEN THE CAR 900MILES IN ACTUALITY, THE ODOMETER WOULD READ 1000MILES AND HENCE THE CAR IS AGING AT A FASTER RATE AS FAR AS MILEAGE IS CONCERNED AND ALSO THAT THE FUEL ECONOMY IS AFFECTED EVEN FURTHER SINCE THE CAR IS NOT GIVING EVEN THE 39-41MILES PER GALLON. THE DEALERSHIP MANAGER CHARLIE MONECO TELLS ME THAT IT IS NORMAL INDUSTRY STANDARDS FOR THE SPEEDOMETER TO BE OFF AND THAT THESE ARE NOT CERTIFIED SPEEDOMETERS. THE DEALERSHIP SERVICE CENTER MANAGER [XXX] TELLS ME THAT THERE IS NOTHING WRONG WITH THE CAR AND THAT IT IS WITHIN LEGAL LIMITS FOR THE SPEEDOMETER TO BE OFF. THE DEALERSHIP SERVICE CENTER TECHNICAL MANAGER [XXX] BLANK TELLS ME THAT THEY TEST DROVE TO LIKE VEHICLES AND FOUND THAT BOTH VEHICLES DID THE SAME MILEAGE AND HENCE THE CONCLUSION THAT THERE IS NOTHING WRONG WITH MY CAR. I QUESTIONED THE TESTING PROCESS SINCE THERE IS NO OUTSIDE SOURCE LIKE A RADAR THAT IS CLOCKING ANY OF THE CARS TO TELL WHICH ONE IS AT WHAT SPEED. CALLED TOYOTA MOTOR CORPN. AT 1-800-331-4331 AND SPOKE TO [XXX] AND SHE SAYS THAT IF THE DEARLERSHIP AND ITS SERVICE CENTER IS SAYING THAT THEY CAN DO NOTHING, THEN THEY STAND BY THE DEALERSHIP. TOYOTA CANNOT HELP ME ANY FURTHER. THE CASE NUMBER FROM TOYOTA IS # [XXX] LODGED TODAY 12.06.2010. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

MY WINDSHIELD WIPERS STOPPED WORKING FOR A SHORT TIME. I HAVE AN IDEA OF WHAT COULD CAUSE THIS ISSUE AMONG OTHER PROBLEMS. I HAD A PROBLEM WITH A VEHICLE I ONCE OWNED THAT THE ENGINE WOULD STOP FOR NO REASON. THE DEALER COULD NOT FIND A PROBLEM BUT AS A PRECAUTION HE REPLACED THE SMALL WIRING HARNESS. MY CAR NEVER FAILED AGAIN. ABOUT 6 MONTHS LATER AMC CAME OUT WITH A DIRECTIVE TO REPLACE THE SMALL WIRING HARNESS ON ALL OF THESE CARS. THE PROBLEM WAS THAT THE TWO ENDS OF THE HARNESS WERE MANUFACTURED BY DIFFERENT COMPANIES THAT USED DIFFERENT PLASTIC.THE PLASTIC IN THE CONNECTORS WOULD REACT WITH ONE ANOTHER AND PRODUCE A GAS. THE GAS WOULD COAT THE CONTACTS AND CAUSE THEM TO GO OPEN. IN MY CASE WHEN I RESTARTED MY CAR THE CONTACTS WOULD ARC AND IT WOULD RUN OKAY UNTIL THE CONTACTS GOT COATED AGAIN. I THINK THIS CONDITION COULD CAUSE ALMOST EVERY PROBLEM TOYOTA IS HAVING. I DON'T KNOW IF THIS CONDITION IS RELATED TO ANY OF THE PROBLEMS THEY ARE HAVING BUT IT MIGHT BE WORTH LOOKING INTO IT. *TR

MY 2010 TOYOTA PRIUS WOULD NOT START AFTER A BRIEF 45 MINUTE LUNCH WITH FRIENDS. WHEN I RELEASED THE PARKING BRAKE AND LET OFF THE BRAKE PEDAL I DIDN'T KNOW THE CAR WAS STUCK IN NEUTRAL. THIS ERROR WAS ON THE DASHBOARD "MALFUNCTION WHEN PARKING, PARK IN A FLAT PLACE AND APPLY PARKING BRAKE SECURELY". WHEN I LET OFF THE BRAKE THE CAR ROLLED BACK INTO THE MIDDLE OF THE PARKING LOT. I HAD TWO COWORKERS IN THE CAR WITH ME; THEY GOT OUT AND PUSHED THE CAR OUT OF THE WAY TO A FLAT LOCATION. CAR STILL WAS DISABLED. I CALLED TOYOTA ROADSIDE ASSISTANCE AND WAITED AN HOUR FOR A TOW TRUCK; AFTER ABOUT 45-50 MINUTES OF WAITING I WAS HIT BY A WOMAN THAT WASN'T PAYING ATTENTION; SHE BACKED INTO THE SIDE OF MY DISABLED CAR. I WAS PRESSING ON THE HORN AND SHE DIDN'T HEAR. THE IMPACT MUST HAVE FREED SOME STUCK COMPONENT OR SOMETHING BECAUSE 2 HOURS LATER WHEN THE TOW TRUCK FINALLY CAME, THE CAR WORKED AGAIN; NO WARNING LIGHTS ETC. TOYOTA LOOKED AT THE CAR AND SAYS THERE IS NOTHING WRONG. I TOOK A PHOTO TO DOCUMENT THE WARNING MESSAGE (PLUS HAVE 2 WITNESSES). *TR

DP22005 · Pedestrian Alert Sounds
Opened Jan 27, 2023 · Closed Aug 7, 2023
Status: closed (inferred from source dates) · Electrical System:propulsion System
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.
DP19004 · Brake Actuator Valve Wear
Opened Sep 30, 2019 · Closed Jan 21, 2021
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.
PE10006 · Braking Performance, Hybrid Vehicle

The subject vehicles are the first model year of a new design generation of the Prius model line.The vehicles are powered by a hybrid drive system that uses both a regenerative braking system, which converts vehicle momentum into electrical energy to be stored in onboard batteries, and a hydraulic brake system more typical of the brake system used on non-hybrid vehicles.As is the case for other similarly designed hybrid vehicles the interaction and management of the two braking systems during ABS braking is complex and requires a sophisticated control system.In a February 9, 2010 Defect Information Report, Toyota advised the agency of its plans to conduct a safety recall to address inconsistent brake feel and increased stopping distances that may occur during braking events requiring ABS operation, such as would occur when braking on rough or low friction road surfaces.Toyota will reprogram the ABS control unit with improved software that addresses this condition.Based on Toyota's action the investigation is closed. ODI will continue to monitor the subject vehicles' performance and will take further action as future circumstances dictate.
