THE CRUISE CONTROL DISENGAGE MECHANISM IN MY 2010 TOYOTA PRIUS DOES NOT DISENGAGE QUICKLY ENOUGH WHEN DEPRESSING THE BRAKE. I HAVE TO PRESS THE BRAKE HARDER THAN ANY PRIOR VEHICLES I HAVE OWNED TO KILL THE CRUISE CONTROL AND IF I RELEASE THE BRAKE BEFORE THE CRUISE CONTROL IS RELEASED THEN THE CAR LURCHES FORWARD. THIS IS A SAFETY ISSUE WITH THIS VEHICLE AND I CALLED TOYOTA AND THEY SAID THAT THERE IS NO SAFETY ISSUE AND WOULD NOT SPEAK TO ME FURTHER ABOUT IT WITHOUT GOING TO THE DEALER. THE DEALER HAD ALREADY TOLD ME THAT IT IS OPERATING NORMALLY AND THAT THIS IS HOW THE 2010 NEW PRIUS MODEL YEAR OPERATES. I HAVE A 2006 PRIUS AS WELL AND THE CRUISE DISENGAGES NORMALLY. MANY OTHER PEOPLE HAVE EXPERIENCED THIS ISSUE AND HAVE DOCUMENTED THEIR EXPERIENCES ON THE FORUM PRIUSCHAT.COM . THEY HAVE EVEN FIXED THE PROBLEM THEMSELVES BY MOVING THE CRUISE CONTROL DISENGAGEMENT CLOSER TO THE TOP OF THE BRAKE PEDAL. OTHERS HAVE REPORTED THAT THEY CAN DEPRESS THEIR BRAKES AND SLOW DOWN THE VEHICLE WITHOUT THEIR BRAKE LIGHTS COMING ON AND THIS IS THE SAME PROBLEM BECAUSE THE BRAKE LIGHTS AND CRUISE CONTROL KILL SWITCH ARE LINKED TOGETHER. *TR

WAS DRIVING PRIUS 2010 MODEL II WITH BRAKE SOFTWARE APPLIED BY DEALER ABOUT 1.5 MONTHS AGO. TODAY (7/27/2010) I EXITED HIGHWAY AND BEGAN GENTLE BRAKING ON OFFRAMP, AS SUGGESTED BY MANUAL TO MAXIMIZE REGENERATION. ABOUT HALF-WAY DOWN OFFRAMP, I REALIZED CAR IN FRONT OF ME WAS COMPLETELY STOPPED AND THAT I HAD TO STOP MUCH MORE QUICKLY THAN I WAS PLANNING TO. I DON'T RECALL BEING PARTICULARLY DISTRACTED, BUT I CAN'T RULE OUT I NOTICED THE STOPPED VEHICLE LATER THAN I SHOULD HAVE. IN ANY EVENT, I'M NOT SURE HOW HARD I PRESSED THE BRAKES, BUT I RECALL DISTINCTLY THINKING "OH, MY GOD. NOTHING IS HAPPENING" AND 1-2 SECS LATER I PLOWED INTO THE CAR IN FRONT OF ME. THE COLLISION WAS HARD ENOUGH TO CAUSE TEMPORARY PAIN TO THE DRIVER IN FRONT OF ME, BUT NO AIR BAGS WERE DEPLOYED AND THE PRIUS APPEARS TO NOT HAVE MAJOR FRONTAL DAMAGE - HOOD IS BENT BACK AND MAYBE SLIGHT FRAME DISTORTION => THE IMPACT CLEARLY WAS NOT AT THE ~40-50 MPH I WAS GOING WHEN JUST EXITING THE HIGHWAY, SO SOME BRAKING CLEARLY DID OCCUR -- BUT I HAVE THE DISTINCT FEELING THAT MY PREVIOUS CAR (SUBARU OUTBOOK) WOULD HAVE EASILY STOPPED IN TIME. AFTER ACCIDENT, I TESTED BRAKES BY GOING 15-20 MPH IN PARKING LOT AND BRAKING HARD. ALWAYS STOPPED QUICKLY, I'M GUESSING W/100% FRICTION BRAKING. SO BRAKES ARE PROBABLY NOT "DEFECTIVE" IN SENSE OF LOST HYDRAULIC FLUID, ETC... BUT I HAVE NEVER BEFORE EXPERIENCED THE FEELING "I'M NOT STOPPING" EXCEPT ONCE WHEN LOSING TRACTION ON ICY ROAD WITH A NON-HYBRID. THE FACT HAD TIME TO THINK THIS THOUGHT AT ALL PROBABLY MEANS MAYBE 0.5-1.5 SEC PASSED WHILE BRAKING INEFFECTIVE. CHECKED FOR TIRE/SKID MARKS ON ROAD OR EVIDENCE OF STRONG TIRE WEAR AND FOUND NONE, WHILE I HAVE ON OTHER CARS WHEN I HAVE HAD TO BRAKE HARD => PRIUS NOT BRAKING HARD DESPITE EMERGENCY. SEEM TO HAVE BEEN CAUGHT IN TRANSITION BETWEEN REGEN & FRICTION MODE? THIS IS STILL DISCUSSED IN PRIUS FORUMS -- SOFTWARE FIX NOT GOOD ENOUGH!? THIS IS POTENTIALLY VERY DANGEROUS. BTW,CAR WAS IN "ECO" MODE. *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

MY 2010 TOYOTA PRIUS LOSES BRAKING ABILITY AND LUNGES FORWARD WHILE BRAKING ON ANY UNEVEN SURFACE I.E. POTHOLE, MANHOLE COVER, BUMP METAL PLATE OR STRIP, ETC... THIS HAS LEAD TO SEVERAL NEAR MISS COLLISIONS AND DUE TO THE AMOUNT OF TIME I SPEND IN THE CAR HAPPENS AN AVERAGE OF 3 TIMES PER DAY. BECAUSE I FEAR FOR MY OWN SAFETY I DO NOT ALLOW PASSENGERS IN MY CAR AND I WILL NOT LET ANYONE ELSE DRIVE MY CAR. I'VE HAD TO ADJUST MY DRIVING TO TRY AND COMPENSATE FOR NO BRAKING ABILITY AT ANY GIVEN TIME. I HAVE NOW REPORTED THIS PROBLEM TO MY DEALER TOYOTA OF MERRILLVILLE IN PERSON 3 TIMES AND OVER THE PHONE ON SEVERAL OCCASIONS AND EACH TIME I WAS TOLD THEY WERE UNABLE TO DUPLICATE THE PROBLEM AND THEREFORE THERE WAS NO FIX THEY COULD OFFER. THEY ALSO TELL ME THAT I AM THE ONLY CUSTOMER REPORTING THIS TYPE OF CONCERN BUT I HAVE BEEN ABLE TO CONNECT WITH MANY PRIUS OWNERS EXPERIENCING THIS LOSS OF BRAKING WHILE OVER UNEVEN PAVEMENT. I BELIEVE TOYOTA IS DOWNPLAYING THIS PROBLEM AT THE RISK OF PUBLIC SAFETY. *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.

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.

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

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.
