I HAVE FILED A COMPLAINT HERE BEFORE ABOUT MY 2010 TOYOTA PRIUS, WHERE THE BRAKES WERE SUPPOSEDLY FIXED LAST WEEK BY TOYOTA FOLLOWING THE RECALL. HOWEVER, JUST TODAY THE BRAKING PROBLEM, WHEN HITTING BUMPS IN THE ROAD, SEEMS TO NOT HAVE BEEN FIXED AT ALL. DRIVING IN THE DC AREA, WHERE THERE ARE A LOT OF POTHOLES AROUND, IT IS EASY TO TEST WHETHER THE BRAKES ARE FIXED OR NOT. WHILE DRIVING ALONG THE ROAD TODAY, NEARING MY HOUSE, I HIT A POTHOLE, AND JUST AS IT HAD BEEN HAPPENING BEFORE, THE BRAKES SEEMED TO COMPLETELY LET GO AND THE CAR LURCHED FORWARD FOR A SPLIT SECOND UNTIL THE BRAKES SEEMED TO REGAIN POWER AND I WAS ABLE TO PRESS DOWN ON THEM AGAIN. PRIOR TO THAT INCIDENT, AND NOT 10 MINUTES EARLIER, I HIT A SMALL POTHOLE WHILE BRAKING LIGHTLY AND THE BRAKES GAVE OUT JUST SLIGHTLY. IT'S AN UNMISTAKABLE FEELING, HAVING EXPERIENCED IT NUMEROUS TIMES BEFORE TOYOTA FINALLY DECIDED TO RECALL THE 2010 PRIUS. *TR UPDATED IVOQ 07/08/10.*JB

MY 2010 PRIUS HAD THE BRAKE SOFTWARE UPDATED BEFORE I PURCHASED IT. I HAVE OWNED THE CAR FOR 12 DAYS. DURING THAT TIME I HAVE EXPERIENCED A BRAKING PROBLEM ON 3 INSTANCES. IN EACH CASE I WAS SLOWING DOWN AT A CONSTANT RATE OF DECELERATION WHEN I HIT A POTHOLE OR OTHER ROUGH SURFACE. FOR A SPLIT SECOND THE RATE OF DECELERATION WAS INTERRUPTED. IN OTHER WORDS IT FELT LIKE I HAD LET UP ON THE BRAKE WHICH I DID NOT DO. ON THE THIRD INCIDENT MY WIFE WAS A PASSENGER IN THE CAR AND ALSO NOTICED THAT FOR A SPLIT SECOND IT FELT LIKE I EASED OFF THE BRAKE. I TOOK MY CAR TO THE TOYOTA DEALER TO MAKE SURE THE SOFTWARE HAD BEEN UPDATED. THEY CONFIRMED THAT IT HAD AND MAKE A NOTE OF MY EXPERIENCE. I HAVE READ ABOUT THE PROBLEM WITH THE BRAKES ON THE HYBRID FORD FUSION AND THE PROBLEM WITH MY CAR MAY BE THE SAME. THAT IS THAT THE ROAD BUMP PROMPTS THE COMPUTER TO MOMENTARILY INTERRUPT THE REGENERATIVE BRAKING AND THUS MAKE IT FEEL LIKE THE BRAKES FAILED. *TR

COMPLAINT REGARDING: 2010 TOYOTA PRIUS. SINCE I PURCHASED THE CAR IN SEPTEMBER OF 2009, THE BRAKES FAIL WHEN I AM BRAKING AND HIT A BUMP, POTHOLE, OR UNEVEN ROAD SURFACE. THE BRAKES FAIL FOR A SECOND OR TWO, AND SOMETIMES THE CAR LURCHES FORWARD. THE ISSUE OCCURS APPROXIMATELY ONCE A DAY, EVERY DAY. ON MARCH 6, 2010, I HAD THE RECALL SOFTWARE FOR THE 2010 PRIUS DONE IN THE SERVICE DEPARTMENT AT THE MIKE CALVERT TOYOTA DEALERSHIP IN HOUSTON, TEXAS. ON THE WAY HOME, I EXPERIENCED THE BRAKE FAILURE AGAIN WHEN I WAS BRAKING AND DROVE OVER A SMALL POTHOLE. I EXPERIENCED THE PROBLEM LATER THAT DAY WHEN BRAKING TO STOP AT A RED LIGHT, THE PAVEMENT SURFACE DESCENDED SLIGHTLY BENEATH THE CAR, THE BRAKES LAPSED, AND THE CAR LURCHED FORWARD. I CALLED THE DEALERSHIP. THEY REFERRED TO THE MATERIALS SUPPLIED BY TOYOTA AND TOLD ME TO CALL TOYOTA AT 1-800-331-4331 TO NOTIFY TOYOTA THAT THE RECALL FIX DID NOT WORK. UPON CALLING THIS NUMBER AND NAVIGATING THE OPTIONS ON THE AUTOMATED SYSTEM, I SAT THROUGH A LONG RECORDING STATING THAT THERE WAS A RECALL OF THE 2010 PRIUS. THE OPTION AVAILABLE TO SPEAK WITH AN AGENT DID NOT ALLOW ME TO DO SO. *TR

I WAS DRIVING MY BRAND NEW, 3 WEEKS OLD, 2010 TOYOTA PRIUS ON A RURAL ROAD IN CLARK COUNTY WASHINGTON ON THURSDAY, MARCH 4, 2010, WHEN I ATTEMPTED TO SLOW DOWN TO MAKE A VERY SHARP LEFT TURN. I WAS APPLYING MY BRAKES WHEN ALL OF THE SUDDEN I REALIZED I WAS NOT SLOWING DOWN MUCH AND WAS NOT GOING TO MAKE THE TURN. I HAVE MANEUVERED THIS TURN HUNDREDS OF TIMES AND KNOW THAT ONE MUST SLOW TO ALMOST A CRAWL TO MAKE THE TURN. I TRAVEL THIS AREA AT LEAST 1-2 TIMES PER WEEK, SO I WAS NOT UNFAMILIAR WITH THE TURN. IT FELT LIKE MY CAR INITIALLY SLOWED SOME, BUT THEN SLOWING CEASED AND I ENDED UP ON EMBANKMENT. THE FRONT OF MY CAR WAS DAMAGED SEVERELY. I WAS NOT HURT BUT LEFT WITH A VERY FRIGHTENING EXPERIENCE TO DEAL WITH. I AM A EXCELLENT DRIVER AND HAVE NEVER HAD A WRECK IN THE 31 YEARS I HAVE BEEN DRIVING. I BELIEVE MY BRAKES INITIALLY ENGAGED, BUT THEN DUE TO THE RURAL ROAD SURFACE, AND PEBBLES LEFT ON THE ROAD FROM PREVIOUS ICE AND SNOW, MAY HAVE CAUSED MY BRAKES TO NOT WORK AS THEY SHOULD HAVE. I ATTEMPTED TO CONTACT TOYOTA BUT THEY ARE CLOSED DUE TO IT BEING THE WEEKEND. MY CAR IS AT THE AUTO BODY SHOP AS I WRITE THIS LETTER. MY CONCERN IS THAT I WAS ALLOWED TO PURCHASE A VEHICLE, THAT IS ON THE RECALL LIST WITH SUCH A DANGEROUS DEFECT SUCH AS "THE BRAKES NOT WORKING PROPERLY." I HAVE A TEENAGE SON WHO IS JUST LEARNING TO DRIVE AND WOULD IT HAVE BEEN HIM, THE ACCIDENT MAY HAVE BEEN WORSE. PLEASE ADVISE HOW YOU BELIEVE I SHOULD PROCEED. I AM VERY CONCERNED, UPSET, AND DO NOT FEEL SAFE IN THIS CAR! AND I CERTAINLY DO NOT WANT TO TRANSPORT MY CHILDREN, OTHER FAMILY MEMBERS AND FRIENDS IN AN UNSAFE VEHICLE THAT I JUST SPENT $33,000.00 ON. I WAS TOLD WHEN I PURCHASED THE CAR THAT IT WOULD BE SAFE, FINE TO DRIVE, AND MAY NOT EVEN BE ON THE RECALL LIST. IT IS ON THE LIST AND IT IS NOT A SAFE VEHICLE AS FAR AS I AM CONCERNED. *TR

BRAKES TEMPORARILY DISENGAGE WHEN BRAKING. THIS HAPPENS SEVERAL TIMES A WEEK. TOYOTA SAYS THEY INSTALLED THE PROGRAMMING FIX A FEW WEEKS AGO BUT THE PROBLEM CONTINUES TO HAPPEN. I CONTACTED THE DEALERSHIP AND THEY TOLD ME THERE WAS NOTHING THEY COULD DO ABOUT IT, THAT I SHOULD CONTACT TOYOTA CUSTOMER SERVICE. THE FAILURE OCCURS WHEN I'M BRAKING AND HIT A BUMP OR UNEVEN PAVEMENT. THE BRAKES STOP BRAKING FOR JUST A MOMENT. DEPENDING ON MY SPEED AT THE TIME, IT CAN FEEL LIKE A MOMENTARY PAUSE OR A SUDDEN, HEAVY PUSH FROM BEHIND. IT ALWAYS FEELS LIKE I"M SLIDING OVER THE BUMP. *TR

Toyota is recalling certain model year 2010 through 2014 Prius vehicles. In the affected vehicles, the Intelligent Power Module (IPM) inside the inverter module (a component of the hybrid system) contains transistors that may become damaged from high operating temperatures.

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.
