I PURCHASED A 2010 PRIUS LEVEL 4. INCLUDED IN THIS PACKAGE IS AN AUTO DIMMING REAR VIEW MIRROR WITH HOMELINK. THE AUTO DIMMING FUNCTION DOES NOT WORK PROPERLY. IT SEEMS TO BE VERY DISTANCE DEPENDENT. THERE IS A NARROW FOCAL RANGE THAT THE SENSOR REACTS TO. IF A VEHICLE IS TO CLOSE OR TO FAR AWAY THE AUTO DIMMING FUNCTION DOES NOT REALLY DIM VERY MUCH. CONSIDERING HOW LOW THE VEHICLE IS THIS IS INCREDIBLE ANNOYING AND UN-SAFE. ALSO THIS VEHICLE HAS SPLIT REAR GLASS IN THE HATCH BACK. THE CENTER BAR I BELIEVE ALSO BLOCKS THE LIGHT FROM HEADLIGHTS FROM REACHING THE SENSOR. IF YOU TILT THE MIRROR UP SO THAT YOU DO NOT SEE THE CENTER BAR (ONLY THE TOP PORTION OF THE REAR GLASS), THE MIRROR SEEMS TO WORK BETTER. AS A SIDE NOTE, I PURCHASED A MANUAL FLIP MIRROR WITH THE CORRECT PART # FOR A 2010 PRIUS FROM MY LOCAL TOYOTA DEALER AND THE NEW MIRROR HAS A DIFFERENT MOUNTING STYLE. *TR

WHILE DRIVING MY 3 WEEK OLD 2011 TOYOYA PRIUS WITH 1700 MILES ON THE ODOMETER ON THE FREEWAY DRIVING MY DAUGHTER BACK TO SCHOOL MY REAR PASSENGER SIDE YOKOHAMA AVID TIRE EXPERIENCED A BLOWOUT. AFTER SUCCESSFULLY MANEUVERING THE CAR OFF OF THE FREEWAY AND TO A SAFE LOCATION I INSTALLED THE SPARE DONUT AND THEN INSPECTED THE TIRE. THE INSIDE SIDEWALL BURST OPEN AND NO ROAD HAZARD WAS PRESENT. I FILED A CLAIM WITH YOKOHAMA TIRES AND THEY HAD ME HAVE THE TIRE INSPECTED BY DISCOUNT TIRE IN SCOTTSDALE, AZ. THEIR INSPECTION SUGGESTED A MANUFACTURERS DEFECT SINCE THEY COULD NOT LOCATE ANY PUNCTURES OR OTHER TYPE OF ROAD HAZARD. AT THE TIME OF THE BLOWOUT I WAS 75 MILES FROM FLAGSTAFF, AZ, MY FINAL DESTINATION ON A SUNDAY LATE AFTERNOON AND COULD NOT LOCATE AN OPEN TIRE DEALER OR TOYOTA DEALER THAT WAS OPEN SO I CONTINUED ON THE DONUT AT 50 MPH TO FLAGSTAFF AND LOCATED AN OPEN SEARS THAT HAD THE RIGHT SIZE REPLACEMENT TIRE BY ANOTHER MANUFACTURER. I HAD SEARS INSPECT THE BLOWN OUT TIRE AND THE REST OF THE TIRES AND THEY CONCLUDED THAT THE TIRE WAS DEFECTIVE BASED ON THEIR OBSERVATIONS. I REQUESTED THAT YOKOHAMA PROFESSIONALLY INSPECT THE TIRE LOCAL TO ME SO THAT I CAN CARRY IT IN AS OPPOSED TO SHIPPING IT TO THEM. PLEASE LET ME KNOW YOUR THOUGHTS AND IF THERE IS ANYTHING ELSE THAT I SHOULD DO TO DOCUMENT THIS ISSUE. **PLEASE NOT THAT THIS OCCURRED ON A 2011 TOYOTA PRIUS*** THERE WAS NO PRIUS MODEL LISTED UNDER 2011 TOYOTA MODELS....PLEASE CORRECT. *TR

DEAR SIR OR MADAM, A FEW DAYS AGO I FOUND ABUNDANT EVIDENCE OF MICE ACTIVITY IN THE CABIN OF MY 16 MONTH OLD TOYOTA PRIUS. AFTER SOME INTERNET RESEARCH I FOUND OUT THAT THIS IS UNFORTUNATELY AN EXTREMELY COMMON PROBLEM WITH PRIUS MODEL CARS AND OTHER TOYOTA MODELS. THE PRESENCE OF RODENTS IN THE ENGINE AREA IS OF COURSE UNAVODIABLE BUT THIS IS THE FIRST TIME I HEAR ABOUT THE CAR DESIGN ALLOW MICE TO EASILY MOVE INTO THE CABIN. THIS OBVIOUSLY HAS SEVERE CONSEQUENCES: I ALREADY HAVE TO REPLACE THE AIR FILTER AND THE PADDING BEHIND THE GLOVES COMPARTMENT AND I AM NOT SURE IF ANY OTHER PARTS HAVE BEEN CHEWED AWAY. MORE IMPORTANTLY THIS IS CERTAINLY A HEALTH AND SAFETY CONCERN. I HAVE TO GET THE CAR DETAILED AND THE AIR SYSTEM FLUSHED TO AVOID TOXIC CONTAMINATION FROM MOUSE EXCREMENTS, AND THIS ENDANGERS ME EVERY TIME I DRIVE: A MOUSE CRAWLING IN THE CABIN OF THE CAR WHILE I AM DRIVING IS A MAJOR SAFETY ISSUE! IT APPEARS THAT THE PLACING OF SCREENS IN AS FEW AS 4 PARTS OF THE AIR SYSTEM WOULD STOP THE MOUSE ACCESS TO THE CABIN, BUT TOYOTA, BOTH MY LOCAL DEALER AND THE NATIONAL SERVICE CENTER, CLAIM THERE IS NOTHING THE CAN OR WILL DO, AND THAT, DESPITE THE ABUNDANT EVIDENCE TO THE CONTRARY, THIS IS A NORMAL OCCURRENCE IN ALL CARS. MANY PEOPLE HAVE POSTED ONLINE ABOUT MICE AND RODENTS IN THEIR PRIUS CARS. A FEEL THIS IS A MAJOR SAFETY ISSUE WITH THE CAR, AND I AM EXTREMELY DISAPPOINTED THAT NEITHER THE LOCAL DEALER NOR THE TOYOTA CORPORATE SERVICES ARE WILLING TO HELO ME SOLVE THIS SITUATION AND PREVENT IT FROM HAPPENING AGAIN. I THINK THE CONSEQUENCES OF THIS DESIGN DEFECT SHOULD BE COVERED UNDER THE WARRANTY AND TOYOTA SHOULD DESIGN A SCREE PART TO COVER THE VENTS WHERE NECESSARY TO PREVENT THIS FROM HAPPENING IN THE FUTURE. *TR

ON THE DAY PRIOR TO THE EVENT, THE WEATHER WAS AROUND 55 DEGREES AND MISTY WITH OCCASIONAL LIGHT RAIN. OUR 2010 TOYOTA PRIUS IV WAS PARKED DURING MOST OF THE DAY. WHILE DRIVING ON INTERSTATE 35 IN TEXAS GOING 70 MPH, ALL OF A SUDDEN 4 DIFFERENT WARNING LIGHTS ILLUMINATED ON THE DASH ALONG WITH THE LARGE RECTANGULAR WARNING MESSAGE SAYING "CHECK HYBRID SYSTEM". THE VEHICLE LOST POWER TO THE WHEELS, THE ACCELERATOR DID NOT WORK EVEN THOUGH THE GASOLINE ENGINE WAS STILL RUNNING, THE VEHICLE COASTED TO THE SHOULDER WHERE IT WAS IMMOBILE AND HAD TO BE TOWED TO THE NEAREST TOYOTA DEALERSHIP. THIS WAS THE FIRST TIME WE HAD ANY TROUBLE WITH THE VEHICLE. THE ODOMETER READING WAS ~3,500 MILES. THE DTC CODE WAS DTC P0A3F "DRIVE MOTOR A POSITION SENSOR CIRCUIT". THE DEALER INITIALLY REPLACED THE ENTIRE INVERTER ASSEMBLY, WHICH DID NOT CORRECT THE PROBLEM. THEN THEY REPLACED THE ENTIRE TRANSAXLE FOR THE VEHICLE. THIS CORRECTED THE PROBLEM. I DO NOT HAVE EITHER OF THE PARTS THAT WERE REPLACED, ALTHOUGH I AM SURE TOYOTA DOES HAVE THE PARTS. *TR

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.

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.
