I'VE HAD TWO TOYOTA PRIUS IN MY LIFETIME, A 2005 AND A 2010 TOYOTA PRIUS, BOTH HAVE HAD THE SAME ISSUE WHERE THE ENGINE WOULD EAT UP ALL OF MY OIL, I WOULD HAVE AN OIL CHANGE DONE AND LESS THAN 2 WEEKS LATER I WOULD HAVE TO CHECK THE OIL GAUGE ROD AND FIND THAT THE OIL LEVELS WERE BELOW THE BOTTOM LINE, ALMOST EMPTY! THE ENGINE WOULD BE BURNING OIL AT SUCH AN ALARMING RATE THAT I WOULD REPEATEDLY BRING THE VEHICLE TO TOYOTA FOR OIL CHANGES. I'M VERY UNSATISFIED WITH MY TOYOTA PRIUSES. MY CAR IS CURRENTLY AT 166,384 MILES AND THE ENGINE CYLINDER HAS NOW GIVEN WAY AND ALSO THE HYBRID BATTERY. I'VE GONE ONLY TO TOYOTA DEALERSHIPS TO HAVE PRISTINE CONSECUTIVE SERVICE AND NO THIRD PARTY REPAIR FACILITIES HAVE PROVIDED SERVICE. I AM LOCATED IN SOUTHER CALIFORNIA IN SAN DIEGO. I HAVE SPOKEN TO MANY OTHER TOYOTA PRIUS OWNERS AND IF YOU DO A GOOGLE SEARCH ONLINE AS OF (04/10/17) "TOYOTA PRIUS ENGINE OIL CONSUMPTION" YOU'LL FIND MANY FORUMS WITH "EXCESSIVE CONSUMPTION" FROM MANY OTHER USERS. ONCE YOU REACH PAST THE 140,000 MILE MARK, YOUR CAR IS PRETTY MUCH DONE. CONSIDER BUYING A NEW ONE. TOYOTA PRIUSES AND THEIR ENGINEERS HAVE TO COME UP WITH A WAY TO SATISFY CURRENT AND FUTURE PRIUS OWNERS AS MANY OF US WILL FIND THAT THERE WILL BE MANY PROBLEMS AND ISSUES DOWN THE ROAD.

IN 2016 ABOUT THE 130,000+ MILE MARK ON MY VEHICLE, I STARTED COMPLAINING ABOUT MY CAR CONSUMING OIL. THE DEALER FINDLAY TOYOTA ASSURED ME THAT IT HAD TO DO WITH THE HEAT AND WAS NORMAL. I WAS LEAD TO BELIEVE THE PAPER I SIGNED AFTER THE WORK WAS COMPLETE HAS TO DO WITH THE MAINTENANCE BEING DONE, NO ONE MENTIONED IT MEANT ALL MY CONCERNS WERE ACKNOWLEDGED. THE DAYS CONTINUED AND EVEN IN DURING COLDER MONTHS OF THE YEAR OF 2016, I AGAIN NOTIFIED THE DEALERSHIP OF MY CAR EATING OIL AND IT WAS NOWHERE TO BE FOUND. AGAIN I COMPLAINED AND IT WAS NOT ANNOTATED OR WRITTEN ANYWHERE IN THEIR FILES. IT WAS NOT UNTIL 26,000 MILES PLUS MORE THAT THEY FINALLY ACKNOWLEDGED MY ISSUE AND TOOK THEIR TIME TO SEARCH FOR THE CAUSE. IN THE MONTH OF MARCH 2017, ONE INDIVIDUAL FROM TOYOTA ACTUALLY TOOK HIS TIME AND DID A FULL CHECK, INSTEAD OF THE USUAL ITS HOT HERE AND THAT EATS YOUR OIL EXCUSE, HE GIVE ME AN ANSWER WHICH LEAD TO ME HAVING CONCERNS ABOUT TOYOTA DEALERSHIPS, HE SAID THE PISTONS HAD A LEAK AND IT WAS BURNING UP MY OIL. I CALLED TOYOTA AND FOUND OUT MY CAR HAD A RECALL FOR THIS ISSUE BUT HERE IS THE CATCH, MY CAR WOULD HAVE TO BE UNDER 150,000 MILES, WHICH IT WAS UNDER WHEN I STARTED TO FIRST COMPLAIN. NOW THAT I AM OVER THAT MILEAGE AND WAS NEVER NOTIFIED, GREAT DEALERSHIPS TELL YOU WHEN YOU TAKE YOUR CAR FOR ANY MAINTENANCE ABOUT RECALLS, THEY SAY IT SUP TO ME TO FIX THIS ISSUE THEY KNEW THESE CARS HAVE. SINCE THEY NEVER WROTE DOWN ANY OF MY COMPLAINS, THERE IS NO PROOF OF ME COMPLAINING. THIS CAR BURNS OIL MOVING OR SITTING AS LONG AS THE PISTONS ARE MOVING. WHERE HAS THE HONESTY AND PROFESSIONALISM OF FINDLAY TOYOTA. WHAT IS MY NEXT STEP I ASK THE READER?

CAR PURCHASED NEW AND SERVICED AT TOYOTA DEALERSHIP EVERY 10,000 MILES USING 0-20W SYNTHETIC OIL. AT AROUND 106,000 MILES I NOTICED THE DISPLAY FLASHING SOMETHING BUT COULD NOT, AT THAT TIME, READ WHAT THE WARNING WAS. IT SEEMED TO HAPPEN GOING AROUND CURVES, TURNING ETC. FINALLY, AT MAYBE 107,000 MILES, THE WARNING STAYED ON LONG ENOUGH TO SEE THE LOW OIL WARNING. TOOK THE CAR IN AT 108,000 (NO OIL ON DIPSTICK AT THAT POINT) AND THE SERVICE DEPARTMENT CHECKED FOR LEAKS AND FOUND NONE. I WAS LIGHTLY ADMONISHED BY SERVICE FOR DRIVING WITHOUT OIL. FAIR ENOUGH, I THOUGHT AT THE TIME. I WAS SLIGHTLY CHAGRINED AS I HAVE ALWAYS RELIGIOUSLY HAD MY OIL CHANGED (OR CHANGED IT MYSELF) ON ALL MY CARS AT THE RECOMMENDED INTERVALS WITH NO SIGNS OF A PROBLEM. THE TOYOTA SERVICE DEPARTMENT RECOMMENDED THAT I MONITOR OIL USAGE. I DID, AND TO MY SURPRISE 2,500 HUNDRED MILES LATER, I HAD TO ADD A FULL QUART. THEN 1950 MILES LATER, ANOTHER QUART. YESTERDAY, ANOTHER QUART AT 1048 MILES. VERY DISAPPOINTED AS THE CAR HAS BEEN WITHOUT PROBLEMS UNTIL NOW. HAVE NOT DISCUSSED THIS WITH THE DEALERSHIP, BUT AM NOT ENCOURAGED BY THE TENOR OF COMMENTS POSTED HERE REGARDING TOYOTA STEPPING UP AND ACCEPTING RESPONSIBILITY. I SEE NO NEED, AT THIS POINT, TO PAY TO HAVE AN OIL CONSUMPTION TEST DONE BY THE DEALERSHIP AS THE CAR IS OBVIOUSLY USING AN EXCESSIVE AMOUNT OF OIL.

TOYOTA HAS SERVICE BULLETIN ISSUED IN NOVEMBER 2016 TO COVER THIS CAR BUT INHERENTLY, IT ISN'T COVERED. I HAVE SERVICE RECORDS THAT THIS WAS HAPPENING IN JUNE 2015 AT 82000 MILES, BEFORE I BOUGHT THE CAR IN SEPT 2016. TOYOTA WILL ONLY COVER HALF OF $3000 COST OF REPAIR. ISSUE APPEARS TO BE WIDESPREAD, ACROSS MANY MODELS FROM WHAT I'VE READ ONLINE AND EXPERIENCED IN THE DEALERSHIP. TOYOTA'S FAILURE TO ADDRESS THIS SITUATION WHEN IT HAS BEEN HAPPENING FOR YEARS IS HIGHLY ALARMING, CONSIDERING IT AFFECTS A MAJOR PART OF THE ENGINE.

ON PICKING UP MY PRIUS AFTER ROUTINE MAINTENANCE, I WAS TOLD THAT IT WAS 3 QUARTS LOW IN ENGINE OIL. I WAS STUNNED AS I HAD HAD NO WARNING OF LOW OIL PRESSURE OR LOSS OF PERFORMANCE. THE DEALER IS CONDUCTING AN "OIL CONSUMPTION TEST" TO MEASURE HOW MUCH OIL WILL BE CONSUMED IN 1200 MILES. THE ESTIMATED REPAIR COST WAS $2000, BUT MY HUSBAND WHO IS VERY KNOWLEDGEABLE ABOUT ENGINES DOESN'T BELIEVE THE SUGGESTED REPAIR WILL FIX THE PROBLEM. I HAVE ONLY RECENTLY BECOME AWARE THAT THIS IS A PREVALENT PROBLEM WITH LATE MODEL TOYOTAS, NOT JUST PRIUS. THE CUSTOMER SERVICE AGENT AND THE SERVICE TECH WE SPOKE WITH WERE CAGEY WHEN ASKED HOW FREQUENTLY THEY HAVE SEEN THIS PROBLEM. I BELIEVE TOYOTA IS VERY AWARE OF THE ISSUE, BUT ARE WILLFULLY NOT ADDRESSING A REMEDY.

EXCESSIVE OIL CONSUMPTION AFTER HAVING MY OIL CHANGED AT THE DEALERSHIP AT 100K MILES, I LEFT ON A CROSS-COUNTRY TRIP. DURING THE TRIP, THE LOW OIL PRESSURE SIGNAL FLASHED ON MY DASHBOARD. UPON PULLING OVER AND CHECKING THE OIL, I FOUND THERE WAS NO OIL IN THE ENGINE AT ALL. I ADDED 4 QUARTS CHECKING THE LEVEL IN INCREMENTS WITH THE DIPSTICK, AND CONTINUED. I HAD TO ADD AN ADDITIONAL QUART OF OIL TO THE ENGINE OVER THE FOLLOWING WEEK, UNTIL RETURNING HOME. UPON RETURNING, THE DEALERSHIP REFUSED TO ACCEPT ANY RESPONSIBILITY FOR THE ISSUE AND INFORMED ME THAT I NEEDED NEW PISTONS AND RINGS. THEY DID NOT INFORM ME THAT THIS IS A RECURRING ISSUE WITH MY GENERATION OF PRIUS AND WERE QUITE FIRM THAT IT WAS NOT THEIR PROBLEM. THERE IS NOT REASON THAT A TOYOTA WITH 100,000 MILE ON IT SHOULD RANDOMLY START BURNING EXCESSIVE AMOUNTS OF OIL WITHIN A FEW THOUSAND MILES OF AN OIL AND FILTER CHANGE. ALL OF THE MAINTENANCE IS PERFORMED AT THE DEALERSHIP AT THE SPECIFIED INTERVALS, AND I WOULD EXPECT THAT TOYOTA WOULD STAND BEHIND A TOYOTA THAT IS MAINTAINED PER TOYOTA SPECIFICATIONS. *TR

I TAKE IT IN FOR MAINTENANCE TO THE SAME PERSON AT THE SAME DEALERSHIP SINCE I HAVE OWNED THE CAR NEW. I WAS NOTIFIED OF THIS PROBLEM WITH THE PISTON RINGS WITH THE OTHER TOYOTA MODELS AND THAT SOME OF THE PRIUS MODELS HAVE ALSO HAD THIS ISSUE. THIS HAS ME VERY CONCERNED THAT OTHER OWNERS HAVE BEEN LEFT OUT OF THIS SUIT. CONSIDERING THERE ARE MILLIONS OF PRIUS OWNERS THAT HAVE STOOD BEHIND TOYOTA AND THE PRIUS AS THE TOP HYBRID ON THE MARKET,THERE NEEDS TO BE SOMETHING DONE ABOUT THIS.

In the letter, the petitioner reported experiencing an unexpected and complete loss of brake power while driving, accompanied by multiple dashboard warning lights. This petition is based on the petitioner's direct experience and assessment that ODI closed DP19-004 because its prompting petition was withdrawn by that petitioner. ODI will review the work conducted during DP19-004 and a review of any additional related complaints and crashes via a new defect petition The petition and related materials can be reviewed at NHTSA.gov under the following ODI number:11553736.
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
Opened Feb 3, 2010 · Closed Jul 12, 2010
Status: closed (inferred from source dates) · Service Brakes, Hydraulic; Service Brakes, Hydraulic:antilock/traction Control/electronic Limited Slip; Service Brakes, Hydraulic:antilock/traction Control/electronic Limited Slip:control Unit/module ; Service Brakes, Hydraulic:foundation Components; Service Brakes, Hydraulic:foundation Components:disc; Service Brakes, Hydraulic:power Assist; Service Brakes, Hydraulic:power Assist:hydraulic
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.
