WHILE BRAKING OVER A ROUGH SURFACE SUCH AS POTHOLES, TRAIN TRACKS OR JUST ROUGH PAVEMENT, THE BRAKES FEEL LIKE THEY CUT OUT FOR A BRIEF (WELL UNDER A SECOND) PERIOD. THIS COULD BE ABS ACTIVATING OR IT COULD BE THE CHANGEOVER FROM REGENERATIVE BRAKING TO FRICTION BRAKING OR SOMETHING I AM NOT AWARE OF. I WOULD DESCRIBE THE FEELING AS "FLOATING" OR HITTING A PATCH OF EXTREMELY SLIPPERY ICE OR LIKE MY FOOT HAS SLIPPED OFF THE BRAKE PEDAL. I AM CONFIDENT THAT THIS EVENT INCREASES STOPPING DISTANCE BUT I HAVE NO IDEA HOW MUCH AND IT MAY ONLY BE INCHES. I KNOW FROM READING, THIS HAS BEEN REPORTED YEARS AGO WITH THE PREVIOUS GENERATION PRIUS. OVERALL, I AM EXTREMELY PLEASED WITH THE CAR BUT THIS IS SOMETHING I BELIEVE SHOULD BE INVESTIGATED. OH YES, IT IS FAIRLY EASY TO REPRODUCE AND HAS HAPPENED TO ME 3-5 TIMES IN THE 6000 MILES I HAVE DRIVEN THE CAR. IT IS NOT NEARLY AS TERRIFYING NOW AS IT WAS THE FIRST TIME BUT WHEN IT HAPPENS IT DEFINITELY GRABS YOUR ATTENTION! IT HAS NOT CAUSED ME TO GET IN AN ACCIDENT BUT I BELIEVE THE POTENTIAL IS THERE FOR AN ACCIDENT TO OCCUR. *TR

2010 TOYOTA PRIUS WITH 2500 MILES. SINCE PURCHASED ON 8/2009, I HAD MORE THAN TEN EXPERIENCES OF UNEXPECTED ACCELERATION (SUDDEN UNINTENDED ACCELERATION) ON REVERSE THAT FEEL LIKE TWO OR THREE TIME (STRONGER) FASTER THAN NORMAL REVERSE. ACCOMPANY THE HIGHER SPEED REVERSE, A HEAVY, ABRUPT BRAKING WITH A SLIGHT TOUCH OF THE BRAKE DURING THIS EVENT. THE BIG "JERK" (BRAKING) ROCK THE ENTIRE CAR AND BANGED HEADS AGAIN THE HEADRESTS.THIS ONLY HAPPENED WITH ELECTRIC MODE AND MOST TIME WITH THE CAR PARKED A SLIGHT INCLINE. THIS UNINTENDED ACCELERATION SOMETIME HAPPEN A FEW TIME A DAY OR IT CAN GO TWO, THREE WEEKS WITHOUT ANY PROBLEM. THE DEALER CAN NOT FIND ANYTHING WRONG WITH MY CAR. AND TOYOTA HAVE NO INFORMATION ABOUT THIS PROBLEM. HOWEVER, IF YOU GO TO PRIUSCHAT FORUM UNDER GEN III 2010 PRIUS MAIN FORUM-BRAKING IN REVERSE, THERE ARE MANY PEOPLE WITH THE SAME PROBLEMS. I STRONGLY BELIEVE THIS IS VERY DANGEROUS IF A NEW DRIVER GET IN MY CAR AND NOT KNOW ABOUT IT. THERE IS ONE POST IN PRIUSCHAT FORUM THAT BEST EXPLAIN THE PROBLEM: JUST YESTERDAY, MY PRIUS-III BACKED UP WITH SUDDEN UNINTENDED ACCELERATION, WITH MY FOOT ONLY ON THE BRAKE PEDAL.... I RECOGNIZED WHAT WAS HAPPENING BECAUSE IT HAPPENED ONCE BEFORE, JUST OVER 2 MONTHS AGO. JUST A FEW DAYS AFTER I GOT THE CAR. WHEN I WAS BACKING OUT OF AN INCLINED DRIVEWAY... I SUSPECT THAT SOME UNUSUAL ELEMENT OF THE TIMING OF TURNING THE CAR ON AND SHIFTING INTO REVERSE, AND POSSIBLY THE INTERNAL STATE OF THE COMPUTER AND THE HYBRID POWER SYSTEM COMBINE TO PRODUCE THIS "ABRUPT" REVERSE ACCELERATION AS I AM GENTLY EASING OFF MY FOOT PRESSURE ON THE BRAKE PEDAL... THE ABRUPT BRAKING EFFECT DOES OCCUR, BUT ONLY IN RESPONSE TO THE MUCH MORE DANGEROUS "UNEXPECTED, UNINTENDED" REVERSE POWER (ACCELERATION), TO STOP THE CAR MOTION. NO MATTER HOW GENTLY THE BRAKE IS EASED FURTHER ON TO STOP, THE STOP IS "ABRUPT" BY GARYGID ORANGE COUNTY, CA. I AM TRYING TO WORK WITH TOYOTA ON THIS ISSUE. THANK YOU. *TR

I WAS UNABLE TO SLOW DOWN GOING INTO AN INTERSECTION AT A REASONABLE RATE OF SPEED. WHILE I WAS NOT ACCELERATING, WHEN I APPLIED THE BRAKES THE CAR DID NOT SLOW DOWN AS I WOULD HAVE EXPECTED. THIS SAME BEHAVIOR HAS OCCURRED IN THE PAST SEVERAL MONTHS SINCE I'VE OWNED THE PRIUS 2010 MODEL. IT SEEMS TO SKIP FORWARD OR ACCELERATE WHILE BRAKING ON A DOWNHILL OR UNEVEN SURFACE. BY THE TIME I WAS ABLE TO STOP I THE AIRBAGS HAD GONE OFF AND I HAD HURT MY NECK AND BACK. IT IS A NEW VEHICLE THAT NOW HAS ALMOST $14,000 DAMAGE AND WON'T BE FIXED FOR A MONTH. IF ANYTHING, I'M AN OVERLY CAUTIOUS DRIVER AND WONDERING WHAT I COULD HAVE DONE TO AVOID THE ACCIDENT. *TR

Feb 12, 2014
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. If this occurs, various warning lamps will be illuminated on the instrument panel and the vehicle will have reduced power allowing it to only drive a short distance.
Consequence & remedy
Consequence: The vehicle may enter a fail-safe/limp-home mode that limits the drivability of the vehicle. The hybrid system could also shut down completely resulting in a vehicle stall, increasing the risk of a crash.
Remedy: Toyota will notify owners and dealers will update the software for both the motor/generator control electronic control unit (ECU) and the hybrid control ECU, free of charge. If an owner experiences a failure of the inverter before the vehicle receives updated software, the dealer will repair or replace the inverter assembly with a new one at no charge.

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.

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.
