2010 TOYOTA PRIUS, NO ACCIDENTS, BUT CLOSE CALLS. WHEN I AM SLOWING TO A STOP, AND IF THE VEHICLE HITS A ROUGH SPOT IN THE ROAD, FOR EXAMPLE A POTHOLE, THE BRAKE PEDAL LOWERS SLIGHTLY AND THE CAR APPEARS TO HAVE THE ANTI LOCK BRAKING TAKE OVER AND THE CAR SPEED DECREASES SLOWLY UNDER THE CONTROL OF THE ABS AND MAY NOT STOP IN THE REMAINING DISTANCE TO A STOP SIGH OR TRAFFIC LIGHT. AT LEAST 4 TIMES, 3 SINCE THE SOFTWARE UPDATE FOR MY CAR, I HAVE BEEN STOPPING AND WITHIN ABOUT 20 FEET OF THE STOP SIGH THERE WAS A SIGNIFICANT BUMP OR POTHOLE AND WITH MY FOOT ON THE BRAKE CONTINUOUSLY I NOTICED THAT THE BRAKE PEDAL DEPRESSED SLIGHTLY AND MY RATE OF SLOWING DECREASED AND MY CAR DRIFTED PAST THE STOP SIGN. THIS ALL HAPPENED WITH MY FOOT STILL ON THE BRAKE. I TOLD THE TOYOTA DEALER ABOUT THIS AND WAS INFORMED THAT IT IS THE WAY THE CAR IS DESIGNED, THAT ANY TIME THAT THE COMPUTER SENSES A WHEEL SLIP, THE ABS TAKES OVER. BUT ON DRY ROAD CONDITIONS, THIS IS PROBLEMATIC BECAUSE IN MY AREA THERE ARE OFTEN UN REPAIRED ROADS WITH RUTS, POTHOLES, BUMPS AND ETC. NEAR THE INTERSECTIONS. HAVING THE ABS TAKE OVER PROVIDES A LAG TIME IN THE STOPPING OF THE CAR AND EACH TIME I HAVE GONE PAST THE STOP SIGN AND SLIGHTLY INTO THE INTERSECTION APPROXIMATELY 5 FEET INTO THE PATH OF OTHER VEHICLES. I AM AN ENGINEER WITH NASA AND KNOW WHAT I AM DOING AND HAVE BEEN TOLD THAT THIS IS A DESIGN FEATURE, BUT THIS FEATURE CAN AND HAS LEFT ME EXCEEDING MY PLANNED STOPPING DISTANCE AND COULD HAVE LEAD TO AN ACCIDENT. *TR

MY TOYOTA PRIUS HEADLIGHTS GO OFF FREQUENTLY WHILE DRIVING. I MUST TURN THEM OFF AND ON TO HAVE THEM COME BACK ON. IT USED TO BE ONE OR THE OTHER AT A TIME, HOWEVER NOW BOTH LIGHTS WILL GO OFF AT ONCE. I WAS DRIVING IN VERY DARK CONDITIONS WHEN IT HAPPENED LAST TIME AND THE ROAD WAS PITCH BLACK. THE FACT THAT IT WAS LATE AT NIGHT IS THE ONLY WAY I KNEW BOTH LIGHTS WERE OUT. IF I AM DRIVING AT DUSK OR DAWN, IT IS A MAJOR SAFETY CONCERN BECAUSE IT WOULD BE DIFFICULT TO TELL THAT MY LIGHTS ARE OFF WHILE I'M DRIVING, BUT VERY DIFFICULT FOR OTHERS TO SEE ME COMING DOWN THE ROAD. IT ONLY TAKES A FEW SECONDS FOR AN ACCIDENT TO HAPPEN. THE TOYOTA DEALERSHIP ACKNOWLEDGED THAT IT IS A KNOWN ISSUE AND INITIALLY SAID THAT THE REPLACEMENT WOULD BE COVERED. THEN CAME BACK AND SAID THEY HAVE NOT BEEN RECALLED SO IT WOULD BE OUT OF MY POCKET. I WAS ALSO TOLD THAT I COULD JUST CONTINUE TO TURN THE LIGHTS ON AND OFF WHEN IT HAPPENS BECAUSE THE LIFE OF THE BULBS SHOULD NOT BE UP YET. THAT IS NOT A GOOD SOLUTION TO ME BECAUSE I DON'T ALWAYS KNOW WHEN ONE OR BOTH LIGHTS GOES OUT AND WHEN IT MIGHT BE DIFFICULT FOR OTHER DRIVERS TO SEE ME. I FEEL THAT THIS IS A KNOWN HAZARD THAT SHOULD BE RECTIFIED BY RECALLING/REPLACING THESE BULBS. *TR

THE FIRST TIME I DROVE MY BRAND NEW 2010 TOYOTA PRIUS AT NIGHT AND THE DASHBOARD CLUSTER WAS ILLUMINATED, I SAW WHAT APPEARS TO BE SMUDGES ON THE INSIDE OF THE SPLIT SCREEN. THE DEFECTS APPEAR ONLY ON THE PORTION OF THE SPLIT SCREEN THAT REGULATES THE HYBRID SYSTEM -- IN OTHER WORDS, THE COMPUTER THAT CONTROLS THE CAR. I BROUGHT THE CAR TO MY LOCAL TOYOTA DEALERSHIP FOR A WARRANTY REPAIR. THEY STATED "SOME TYPE OF FLUID OR CLEANER HAS GOTTEN BEHIND THE CLUSTER AND SPOTTED. NOT COVERED BY WARRANTY." IF THIS WERE CORRECT, AND IT IS NOT, THE SCREEN WOULD HAVE TO BE POROUS; WHICH IN ITSELF WOULD BE A MANUFACTURING DEFECT. I CONTACTED TOYOTA CUSTOMER SERVICE IN CALIFORNIA AND THEY STAND BY THE DEALER AND STATE "THIS IS NOT A DEFECT TOYOTA MOTORS WILL COVER. WE CONSIDER YOUR CASE CLOSED." MY PRIVATE MECHANIC THINKS THERE MIGHT BE A PROBLEM WITH THE EVAPORATOR BEHIND AND INTEGRATED WITH THE DASH - COUPLED WITH THE HEAT & HUMIDITY - WHICH MIGHT BE CAUSING THE BLOTTING OUT OF PORTIONS OF THE HYBRID SCREEN CLUSTER. FURTHER, HE TELLS ME THAT WHETHER OR NOT THIS CAN EFFECT THE SAFETY OF THE HYBRID SYSTEM AND THE OPERATION OF THE VEHICLE, HE DOES NOT KNOW. HE STATES THAT IN ORDER TO DETERMINE WHAT IS CAUSING THIS THE COMPLETE DASH ASSEMBLY MUST BE REMOVED. I CANNOT BELIEVE TOYOTA MOTOR CORPORATION HAS LEARNED NOTHING FROM THEIR MISTAKES OF THE RECENT PAST AND IS DENYING ANY RESPONSIBILITY ON THE PART OF THE MANUFACTURER OF THIS BRAND NEW AUTOMOBILE. I BELIEVE THIS PROBLEM IS A MANUFACTURING DEFECT THAT HAS PROBABLY SHOWN UP ON OTHER VEHICLES AND WILL CONTINUE TO SHOW UP ON ADDITIONAL VEHICLES NO MATTER HOW ADAMANTLY TOYOTA MOTOR CORPORATION DENIES IT IS A MANUFACTURING DEFECT. I WATCHED WHAT I THOUGHT WERE SINCERE APOLOGIES BY MR. TOYOTA WHEN HE APPEARED BEFORE THE UNITED STATES CONGRESS. LOOKS AS THOUGH NOTHING HAS CHANGED IN CORPORATE JAPAN TOYOTA. *TR

NEW 2010 PRIUS LL COMMUTER CAR SUDDENLY ACCELERATES OR SCOOTS WHEN BOTH FEET ARE ON THE BRAKE. THE VEHICLE TAKES THE SAME ROUTE TO AND FROM WORK DAILY. ON EVERY TRIP, WHEN THE RIGHT FRONT WHEEL PASSES OVER A RECESSED MANHOLE, THE VEHICLE ACCELERATES. I IMMEDIATELY PUSH HARDER ON THE BRAKE TO STOP THE VEHICLE. THE MANHOLE IS ABOUT 30 FEET IN FRONT OF AN INTERSECTION, SO I AM ALREADY DECELERATING AND BRAKING WHEN I CROSS OVER THE MANHOLE. THIS IS SCARY BECAUSE, IF I THE CAR DOESN'T STOP, IT WILL TAKE ME OUT INTO THE MIDDLE OF THE INTERSECTION. BOTH FEET ARE ON THE BRAKE. I HAVE DRIVEN FOR OVER 40 YEARS, AND THIS THE STRANGEST THING I HAVE EVER EXPERIENCED. *TR

I WAS ON A TRIP TO ARIZONA AND WHEN DRIVING IN MY 2010 PRIUS FROM FLAGSTAFF TO PHOENIX DURING THE EVENING, THE BATTER DISPLAY'S TOP SEGMENT GLOWED RED MANY TIMES IN THE DESCENT FROM FLAGSTAFF. IT WAS A VERY DIFFICULT TO DRIVE TO KEEP THE TOP SEGMENT FROM TURNING RED AS THE VEHICLE WAS COASTING AND I DID NOT WANT TO EXCEED THE SPEED LIMIT SO I REALLY DID NOT NOW WHAT TO DO. I DECIDED TO SHIFT TO NEUTRAL SO THE ENGINE WAS NOT BREAKING. HOWEVER IN NEUTRAL I WAS WEARING OUT MY VEHICLES BRAKES WHICH ALSO WORRIED ME BECAUSE OF THE POSSIBILITY OF OVERHEATING THE BRAKES. I LOOKED IN MY VEHICLE MANUAL BUT NOTHING AS IN THE BOOKLET ABOUT THIS TYPE OF OCCURRENCE. SO I ASKED MY TOYOTA SERVICE PERSONNEL AT RUDY LUTHER TOYOTA IN GOLDEN VALLEY, MN AND THEY HAD NOT HEARD OF THIS PROBLEM. HE GAVE ME A THE TELEPHONE NUMBER FOR CUSTOMER SERVICE REPRESENTATIVES AT TOYOTA AND AFTER DISCUSSING THIS INCIDENT WITH MANY PEOPLE IN CUSTOMER SERVICE AT TOYOTA, THE END RESULT WAS "THAT THE BATTERY WAS FULLY CHARGED AND WHEN THIS OCCURS THE TOP BAR WILL GLOW RED BUT THIS WILL NOT EFFECT THE BATTERY". I DO NOT KNOW IF THIS IS TRUE OR TOYOTA IS JUST PUTTING ME OFF BUT OTHERS AT THE FOLLOWING TOYOTA FORUM HAVE ALSO EXPERIENCED THIS PROBLEM. IS THIS A SAFETY PROBLEM, I DO NOT KNOW. IS IT A BATTERY WARRANTY PROBLEM, I DO NOT KNOW. BUT PLEASE LOOK AT THIS FORUM THREAD AND MAYBE YOU CAN DISCUSS THIS MORE FULLY WITH TOYOTA. HTTP://PRIUSCHAT.COM/FORUMS/GEN-III-2010-PRIUS-MAIN-FORUM/67994-ALL-BARS-BATTERY-INDICATOR-4.HTML ON THE RETURN TRIP AND HERE IN MINNESOTA I HAVE NOT HAD THIS PROBLEM OCCUR AS THERE ARE NOT MANY LONG DESCENTS. *TR

ALTHOUGH I TOOK MY VEHICLE IN FOR THE RECALL (2010 PRIUS) LAST WEEK, THE VEHICLE REPEATED THE LOSS OF BRAKE/SURGE ISSUE THIS MORNING. I ALSO REPORTED TO MY TOYOTA DEALER LAST WEEK ABOUT ABNORMAL, SUDDEN BRAKING. WHEN APPLYING NORMAL PRESSURE TO THE BRAKES, ON SEVERAL OCCASIONS THE BRAKES HAVE LOCKED VIOLENTLY, SENDING ME AND MY PASSENGERS AGAINST OUR SEAT BELTS. TOYOTA CLAIMED THAT THE RECALL MAY MAKE THAT BETTER. IT HAS NOT. THIRDLY, I REPORTED LAST WEEK TO TOYOTA THAT THE CAR HAS ON OCCASION SHAKEN VIOLENTLY AND MADE A LOUD CLANKING NOISE (LIKE A WASHING MACHINE OFF BALANCE) UPON START UP, CAUSING ME TO JUMP OUT F THE CAR FOR FEAR OF IT BLOWING UP.

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.
