THIS IS A COMPLAINT ABOUT A RECURRING EVENT THAT HAS SERIOUS IMPLICATIONS IN THE WRONG SITUATIONS. FOR FIVE TIMES NOW, SINCE DRIVING OUR NEW CAR, OUR BRAKES HAVE RELEASED AFTER GOING OVER A BUMP IN THE ROAD. THIS BUMP CAN BE AS SMALL AS A CRACK CAUSED BY A NEARBY TREE'S ROOTS, OR LARGER LIKE A POTHOLE. IT HAS ALSO OCCURRED WHEN DRIVING OVER SLICK SEWER COVERS. IT TYPICALLY HAPPENS WHEN BRAKING, THEN HITTING THE BUMP, THEN BRAKES RELEASE, AND THE CAR IS NO LONGER BREAKING. THIS IS ESPECIALLY DANGEROUS IN HILLY CITIES LIKE SAN FRANCISCO, WHERE IF THIS HAPPENS GOING DOWNHILL, THE ACCELERATION ACCOMPANIED BY THE LACK OF BRAKING GOING DOWNHILL CAN RESULT IN CRASHING INTO THE NEXT CAR, OR WORSE, HITTING A CROSSING PEDESTRIAN AT A CROSS WALK. *TR

MY 2010 TOYOTA PRIUS BRAKES FAIL ( DISENGAGE OR RELEASE) WHEN BRAKING ON ICY SURFACE OR WHILE BRAKING AND A BUMP OR POT HOLE IS HIT. I FIST NOTICED THIS ISSUE ON DEC. 19, 2009 AFTER A SNOW STORM BUT IT CONTINUES TO HAPPEN EVEN ON DRY ROAD WHEN A SMALL BUMP IS HIT. I REPORTED IT TO TOYOTA AND THEY TOLD ME THEY COULD NOT FIND ANY ISSUES WITH THE BRAKES. NOTHING WAS DONE TO CORRECT THE PROBLEM. THE CAR ACTUALLY GOES FASTER WHEN YOU HIT A BUMP WHILE BRAKING. THE BRAKES RELEASE AND IT FEELS LIKE YOU HAVE NO BRAKES AT ALL FOR A FEW SECONDS. THIS IS NOT RIGHT! IT HAPPENS VERY UNEXPECTEDLY AND YOU CAN NOT JUDGE YOUR BRAKING TIME CORRECTLY. IT HAPPENED TO ME RECENTLY WHEN STOPPING AT STOP SIGN BEFORE ENTERING A CROSS ROAD. I HIT A PATCH OF ROUGH ROAD AND IT DROVE ME TO STOP PASSED THE STOP SIGN AND WAS LUCKY THERE WERE NO ON COMING TRAFFIC. *TR

THERE IS AN APPARENT MOMENTARY LOSS OF BRAKING ABILITY THAT WE HAVE EXPERIENCED SEVERAL TIMES. GOING OVER A RISE IN THE ROAD, OR BUMPS, AND BEGINNING A DESCENT TO AN INTERSECTION, PRESSING THE BRAKE PEDAL SEEMS TO HAVE NO EFFECT FOR ABOUT 500MS. THIS SEEMS SOMEWHAT MORE PRONOUNCED WHEN THE ROAD IS WET, ALTHOUGH POSSIBLY THE EXPLANATION FOR THIS IS WE BRAKE EARLIER IN THE DESCENT AS A PRECAUTION IN LESS-THAN-IDEAL CIRCUMSTANCES. WE HAVE MADE OUR LOCAL DEALER AWARE OF THIS AT THE 5K MILE SERVICE APPOINTMENT, AND THEY ACKNOWLEDGED OTHER COMPLAINTS, AND CONTACT WITH TOYOTA. THEY REPORT THAT TOYOTA IS LOOKING IN TO A FIX. WE ARE CONCERNED ABOUT THE ABILITY TO BRAKE IN AN EMERGENCY SITUATION WITH NO SAFETY MARGIN. THIS SEEMS REPRODUCIBLE. *TR

I HAVE A 2010 PRIUS PURCHASED IN SEPTEMBER OF 2009. IT NOW HAS JUST OVER 5000 MILES ON IT. SINCE THE BEGINNING, PROBABLY THE FIRST WEEKEND I OWNED THE CAR, WHEN BRAKING IF I HIT A BUMP IN THE ROAD, UNEVEN SURFACE, OR A POTHOLE OR SOMETHING, THE CAR OFTEN FEELS LIKE IT LURCHES FORWARD AND I HAVE TO IMMEDIATELY RELEASE AND REBRAKE. THE CAR FEELS OUT OF CONTROL. I HAVE VERY OFTEN FELT LIKE I NARROWLY MISSED LURCHING FORWARD INTO THE CAR IN FRONT OF ME. THE TOYOTA DEALERSHIP SERVICE DEPARTMENT INSISTS THEY ONLY KNOW OF RECALLS REGARDING THE STICKING ACCELERATOR PEDALS, NOTHING ABOUT THIS BRAKING ISSUE. YET I READ PLENTY ONLINE ABOUT THIS PROBLEM, SO I KNOW IT ISN'T ONLY HAPPENING TO ME. WHAT CAN YOU DO?? I'VE LISTED ALL THREE TYPES OF BRAKES IN THE EQUIPMENT AREA OF THIS FORM, BECAUSE I DON'T KNOW WHAT IT IS - SOMETHING ABOUT THE HYBRID BRAKING SYSTEM ALSO CHARGING THE ENGINE? ALSO I LISTED THE DATE AS THE DAY AFTER I BOUGHT THE CAR BUT THIS IS ONGOING, NOT A SINGLE INCIDENT BY ANY MEANS. *TR

FAILURE: AS THE CAR PASSES OVER THE CHOPPY PAVEMENT, BRAKING FORCE DECLINES SHARPLY WITHOUT A CHANGE IN BRAKE PEDAL PRESSURE. THE CONSEQUENCE OF THIS IS THAT THE CAR STOPS FARTHER DOWN THE ROAD THAN EXPECTED DESPITE REFLEXIVE INCREASED BRAKE PRESSURE ON MY PART.

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. The recall began on March 21, 2014. Owners may contact Toyota at 1-800-331-4331.

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.

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.
