DEALER MECHANICS AT TOYOTA BERKELEY, TOYOTA VALLEJO AND CITY IN DALY CITY ALL HAVE STATED THAT THE CRACK IN MY OIL TANK IS A 'WELL KNOWN' MANUFACTURER DEFECT. THE MECHANICS STATE WHEN BUILDING THAT PART, A MACHINE CLAMPED THE 2 PARTS TOGETHER. BUT THE MACHINE DOESN'T WIPE IT DOWN BEFOREHAND AND ANY OIL WILL KEEP THE 2 PIECES SEPARATED, WHICH EVENTUALLY FORM A CRACK. WHEN THE OIL IS LEFT UNCHANGED FOR A PERIOD OF TIME THE CRACK GETS BIGGER, THE OIL LEAKS AND EVENTUALLY DOESN'T WORK. I WAS TOLD IF I KEEP UP WITH MY REGULAR OIL CHANGES, IT SHOULD WORK. BUT I GET ANXIETY NOW EVERY TIME THAT MAINTENANCE LIGHT GOES ON AND I FEEL LIKE I HAVE TO CHANGE THE OIL IMMEDIATELY OR ELSE.

I WAS GOING DOWN THE HIGHWAY AT ABOUT 70 MPH WHEN ALL THE SUDDEN THE PRIUS LOST POWER. THE PRIUS DROPPED DOWN TO ABOUT 55 MPH. AFTER A SHORT PERIOD OF TIME THE POWER PICKED UP. I GOT OFF THE HIGHWAY AND TOOK THE BACK ROADS. IT WAS A VERY HOT DAY.

I ACTUALLY WOULD LIKE TO FILE A CONCERN REGARDING THE 2010 - 2014 INVERTER/COMPONENT FAILURES. THIS PROBLEM WAS BROUGHT TO MY ATTENTION BY MY DEALER INDICATING THAT THE MOTOR/GENERATOR ECU COULD RESET, CAUSING THE HYBRID SYSTEM TO SHUT DOWN, RESULTING IN MY VEHICLE STOPPING WHILE BEING DRIVEN AND SUBJECTING ME OR WHOM EVER IS DRIVING AT RISK OF A CRASH. I CALLED TOYOTA CUSTOMER SERVICE AND SHOW LITTLE CONCERN FOR THIS POTENTIAL PROBLEM BUT JUST TOLD ME THAT I SHOULD VERIFY WITH MY DEALER THAT THE EOE-PRIUS RECALL TO REFRESH SOFTWARE IN THE INVERTER WAS PERFORMED. IT WAS CONFIRMED THAT IT WAS PERFORMED ON MY CAR ON 2/14/14 AT SAN FRANCISCO TOYOTA AND THAT THEY TENDED THE WARRANTY FOR 15 YEARS, UNLIMITED MILEAGE. MY DEALER TOLD ME THAT SOME VEHICLES THAT HAVE HAD THE EOE-PRIUS RECALL HAVE STILL SUFFERED INVERTER FAILURE. IS TOYOTA GOING TO WAIT FOR SOMEONE TO DIE, BEFORE THEY WILL CORRECT THIS PROBLEM. A VERY CONCERNED PIRUS OWNER! IM JUST WONDERING IF I SHOULD SELL MY PIRUS BEFORE IT (TOYOTA) KILLS ME OR SOMEONE I LOVE.

RODENTS CHEWED THROUGH MAJORITY OF THE WIRING UNDER THE HOOD AND BUILD NESTS IN THE ENGINE. THIS HAS HAPPENED TWICE AND I HAVE ONLY OWNED THE CAR FOR 5 MONTHS AND COST ME A LOT OF MONEY FOR REPAIRS WHICH TOYOTA WILL NOT COVER AND SAID IT IS NOT THEIR RESPONSIBILITY FOR USING THESE SOY BASED WIRES THAT ATTRACTS RODENTS.

WITHIN THE LAST SIX MONTHS, AND ABOUT FOUR TIMES, I HAD EXPERIENCED ROUGH/HIGH IDLING DURING HOT DAYS AND AFTER DRIVING OVER 80 MILES; USING AIR CONDITIONING. (I WORK OVER 70 MILES FROM HOME.) I DECIDED TO TAKE THE CAR TO THE TOYOTA OF REDLANDS DEALERSHIP ON AUGUST 4, 2015, BECAUSE THE CAR WAS DISPLAYING THE SAME CONDITIONS. WHILE ON THE WAY TO THE DEALERSHIP, AND ON THE FREEWAY, THE CAR BEGAN TO IDLE HEAVILY. I MERGED TO EXIT THE FREEWAY AND WHILE ON THE OFF RAMP, STOPPED, THE CAR COMPLETELY SHUT OFF. THE DISPLAY READ "CHECK HYBRID ENGINE. STOP PARK THE CAR SAFELY." I WAS ABLE TO RESTART THE VEHICLE TO MOVE FROM OFF-RAMP TRAFFIC AND PARK IT. THE MESSAGE ON DISPLAY WAS STILL THERE. I SHUT OFF THE CAR AND CALLED THE DEALERSHIP. THEY RECOMMENDED I HAVE THE CAR TOWED TO THEM. WHEN TOW TRUCK ARRIVED, I TURNED ON THE CAR TO POSITION IT FOR THE TOWING BED. THE MESSAGE NO LONGER DISPLAYED . THE CAR STAYED WITH DEALERSHIP ALL DAY ON AUGUST 5, 2015. ACCORDING TO THE DEALERSHIP, THE DISPLAY SHOWED NO MESSAGE AND THERE IS NO CODE TO INDICATE A MALFUNCTION OCCURRED. THEY WERE NOT ABLE TO DIAGNOSE THE PROBLEM. I AM KEEPING THE VEHICLE AT THE DEALERSHIP ON AUGUST 6, 2015, FOR FURTHER EVALUATION. MY CONCERN IS TWO-FOLD: 1. MY SAFETY, 2. IF THE SYSTEM DISPLAYED A MESSAGE, WHY DOES THE SYSTEM NOT PRODUCE A CODE FOR THE TECHNICIANS AS A NON-HYBRID CAR WOULD? THIS ITSELF PRESENTS A SERIOUS ISSUE.

WHILE DRIVING ON THE FREEWAY AT HIGHWAY SPEEDS A SERIES OF YELLOW TRIANGLES SUDDENLY FLASHED ON THE DASHBOARD ALONG WITH SOME BEEPS. THE ENGINE THEN STALLED AND THE GAS PEDAL NO LONGER RESPONDED TO ANY INPUTS. DUE TO A COMBINATION OF SHEER LUCK AND DRIVER PRESENCE OF MIND THE CAR WAS STEERED TO THE SHOULDER OF THE HIGHWAY WHERE IT CAME TO A HALT. THE EXPERIENCE OF TRYING TO CONTROL A CAR WITH A STALLED ENGINE AND SAFELY STEER IT TO THE SHOULDER IN HEAVY TRAFFIC WAS TERRIFYING TO SAY THE LEAST. THE CAR WAS TAKEN STRAIGHT TO THE DEALER WHERE IT WAS LEFT FOR SERVICE. AFTER DIAGNOSIS A COUPLE OF DAYS LATER THE DEALER CALLED BACK AND SAID THAT THE ENGINE CONTROL MODULE HAD FAILED WHICH IS WHY THE ENGINE HAD STALLED. THE CAR IS STILL WITH THE DEALER SINCE THE PART IS NOT AVAILABLE AND NEEDS TO BE SHIPPED FROM TOYOTA. THE DEALER CLAIMED THAT THIS WAS SUCH A RARE OCCURRENCE THAT THEY DID NOT HAVE THE PARTS AVAILABLE. THEY ALSO CLAIMED THAT THEY DID NOT KNOW ANYONE ELSE FOR WHOM THIS HAD HAPPENED. MAYBE SO BUT THIS WAS AN INCIDENT THAT COULD HAVE BEEN FATAL. THE FACT THAT NOBODY GOT KILLED IS JUST PLAIN LUCK. *JS

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.
