  I HAVE A 2010 PRIUS. I HAVE NOTICED THAT WHEN I GO OVER UNEVEN GROUND (LIKE POTHOLES OR BUMPS) OR SLICK SURFACES (ESPECIALLY TRAIN TRACKS AND SEWER COVERS) MY BRAKES DON'T SEEM TO WORK. IT FEELS LIKE I AM NOT IN CONTROL OF MY CAR, AND FOR 2-3 SECONDS THE CAR IS NOT BRAKING EVEN THOUGH MY FOOT IS PRESSING ON THE BRAKE. *TR

  IN MY 2010 TOYOTA PRIUS, AS I'M BRAKING ON A ROUGH SURFACE, IT FEELS AS THOUGH THE CAR ACCELERATES FOR A SPLIT SECOND. IT HAPPENED MOST RECENTLY ON 12/22 AS I WAS COMING TO A STOPLIGHT ON A ROAD WITH PATCHES OF SNOW/ICE DEBRIS IN CAMBRIDGE, MA. IT HAS OCCURRED MAYBE 5 TIMES SINCE I BOUGHT THE CAR IN AUGUST, AND AT FIRST I THOUGHT I WAS JUST IMAGINING IT. WHEN IT HAPPENS, MY HEART RACES AND I PRESS THE BRAKE HARDER, WHICH SEEMS TO MAKE IT ENGAGE. THE END RESULT IS THAT THE STOPPING DISTANCE IS LONGER THAN IT SHOULD BE, AND IT'S DEFINITELY SCARY. I TOOK THE CAR INTO THE DEALERSHIP ON WEDNESDAY, DECEMBER 23RD TO HAVE IT CHECKED OUT. THE CAR WAS APPROVED AS FUNCTIONING AS NORMAL, WITH A WRITE-UP SAYING THE MASTER MECHANIC LOOKED AT IT, TOOK IT FOR A DRIVE ON A BUMPY SURFACE, AND CLEARED IT AS FINE. THE CLIENT SERVICES MANAGER EXPLAINED THAT I JUST NEEDED TO GET USED TO THE SENSATION WHEN THE ABS KICKS IN. *TR

  SOMETHING WEIRD HAPPENS WHEN I AM BRAKING. AS I AM SLOWING AND BRAKING EVENLY, THERE IS A VERY BRIEF SURGE LIKE I HIT THE ACCELERATOR, BUT MY FOOT IS NO WHERE NEAR THE ACCELERATOR. IT FEELS LIKE THE BRAKES ARE NOT WORKING AT ALL FOR A BRIEF MOMENT. IT SEEMS TO HAPPEN WHEN I HIT A BUMP, BUT IT CAN ALSO HAPPEN FOR NO APPARENT REASON. IT HAS HAPPENED ABOUT 5 TIMES NOW AND IT SEEMS TO BE INCREASING IN FREQUENCY. IT ALSO HAPPENED ONCE WHEN MY BOYFRIEND WAS DRIVING IT. *TR

• 12/30/2025· SERVICE BRAKES

  On November 25, 2025, at approximately 11:45 p.m., our 2010 Toyota Prius experienced a braking system malfunction during normal operation. The brake pedal required significantly increased effort and the vehicle exhibited reduced braking performance, indicating a loss of brake power assist. The vehicle required increased stopping distance, creating an immediate risk of a collision. At the time of the failure, multiple warning indicators illuminated simultaneously, including the brake system warning, ABS warning, check engine light, battery warning, steering warning, tire pressure warning, and vehicle stability control/slip indicator. There were no warning lamps or abnormal symptoms prior to the failure. The failure was determined to involve the brake booster pump assembly, a component responsible for maintaining hydraulic brake assist pressure. This component is known to experience internal accumulator housing degradation, which can allow nitrogen gas migration into the brake fluid and result in partial or complete loss of brake assist. The affected component remains available for inspection. Following the incident, an authorized Toyota dealership inspected the vehicle and reproduced and confirmed the condition. Service records indicate the brake booster pump assembly had previously been replaced under a Toyota safety recall. Despite this prior recall repair, the same component failed again after approximately 41,000 miles of service, demonstrating that the recall remedy was ineffective. As a result of this failure, the vehicle was rendered unsafe to operate. Despite dealer confirmation that the malfunction involved a previously recalled safety component, corrective repairs were declined, with warranty limitations cited rather than addressing the repeat safety-related failure.

  The driver airbag deployed without an accident while driving in the highway. The airbag deployment caused near control lost of the car. I was lucky to not have any other cars near me so I managed to get the car safely out of the highway. The airbag deployment was scary and caused me not able to see through the windshield due to the gas from the airbag.

  TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT THE VEHICLE WAS SERVICED UNDER NHTSA CAMPAIGN ID NUMBER: 10V039000 (SERVICE BRAKES, AIR: ANTILOCK: CONTROL UNIT/MODULE). THE CONTACT NOTICED THAT AFTER THE RECALL REPAIRS, THERE WAS AN ABNORMAL INCREASE IN STOPPING DISTANCE WHEN BRAKING OVER UNEVEN PAVEMENT. THE CONTACT STATED THERE HAVE BEEN SEVERAL OCCASION WHEN THE VEHICLE FLOATED INTO AN INTERSECTION BECAUSE THE FAILURE PREVENTED THE VEHICLE FROM STOPPING. THE VEHICLE WAS TAKEN TO THE DEALER FOUR TIMES WHERE THE CONTACT WAS TOLD THERE WERE NO FAILURES WITH THE VEHICLE BECAUSE THE BRAKING SYSTEM WAS OPERATING AS DESIGNED.

  WHEN I BRAKE MY PRIUS WHERE THE SURFACE IS VERY ROUGH OR BROKEN, THE BRAKES SEEM TO ENGAGE INITIALLY BUT THEN RELEASE. I HAVE TO PRESS DOWN AGAIN VERY HARD TO GET THEM TO ENGAGE TO THE POINT OF STOPPING THE VEHICLE. YESTERDAY, FOR EXAMPLE, WHILE COMPLETING LONG SLOW BRAKING AT THE BOTTOM OF A STEEP HILL, I ENCOUNTERED SOME ROUGH PAVEMENT JUST BEFORE THE STOP SIGN AND SUDDENLY THE BRAKES SEEMED TO RELEASE. WHEN I FORCEFULLY PRESSED THEM AGAIN, THEY RE-ENGAGED AND STOPPED THE CAR, BUT NOT BEFORE IT HAD NOSED INTO THE INTERSECTION. *TR

  MY NEW 2010 PRIUS HAS A BRAKE PROBLEM. I HAVE OWNED THE CAR ABOUT 2 MONTHS, AND HAVE PUT ABOUT 3000 MILES ON IT. ON THREE OCCASIONS, I HAVE EXPERIENCED A SITUATION WHERE THE BRAKES SUDDENLY RELEASED, AND I HAD TO SLAM ON THE BRAKE PEDAL TO PREVENT AN ACCIDENT. TWO OF THE SITUATIONS HAPPENED WHEN I WAS COMING TO A STOP NEAR AN INTERSECTION (I WAS MOVING INTO A LEFT TURN LANE, AND SUDDENLY THE BRAKES RELEASED). THE THIRD TIME WAS WHILE EXITING A FREEWAY, WHEN I HIT A POTHOLE, AND I FELT THE BRAKE RELEASE. AFTER THE THIRD EXPERIENCE, I RECALLED THAT, PERHAPS, THE CAR RAN OVER A SMALL BUMP WHEN I WAS MOVING INTO THE LEFT TURN LANE, AND THAT MAY HAVE HELPED TRIGGER THE RELEASE OF THE BRAKE PEDAL. I TOOK THE CAR TO THE TOYOTA DEALER WHERE I PURCHASED IT, BUT THEY WERE UNABLE TO FIND ANYTHING WRONG. I SUBSEQUENTLY READ (VIA AN MSNBC NEWS STORY THAT CAME OUT ON DECEMBER 29, 2009, AND WHICH IS AVAILABLE AT THE LINK BELOW) THAT OTHERS ARE HAVING THE SAME PROBLEM THAT I EXPERIENCED.

  2010 TOYOTA PRIUS, 4500 MILES WHILE BRAKING, THE CAR HIT A SET OF FLUSH RAILROAD TRACKS. THE BUMP OF THE TRACKS CAUSED THE BRAKING SYSTEM TO FEEL LIKE IT STOPPED WORKING, AND I HAD TO RE-PUMP THE BRAKES TO GET BRAKING TO RE-ENGAGE. THE CAR HAS HAD A COUPLE MORE SIMILAR EPISODES OF THE BRAKES SEEMING TO DIS-ENGAGE. *TR

  THE ROADS WERE COVERED WITH SNOW AND WERE QUITE SLIPPERY. I WAS COMING DOWN A HILL TO A STOP SIGN AT ABOUT 10 MPH. I HIT THE BRAKES LIGHTLY, THE ABS ENGAGED (I COULD HEAR/FEEL THE BRAKES PULSE), BUT THE CAR DIDN'T SLOW DOWN MUCH. I JAMMED ON THE BRAKES, THE ABS WAS STILL ENGAGED AND THE CAR FINALLY STOPPED IN THE MIDDLE OF THE INTERSECTION, AGAIN SLOWING DOWN VERY SLOWLY. IF IT HAD NOT BEEN A FOUR-WAY STOP, SOMEBODY WOULD HAVE HIT ME! I KEPT DRIVING AND THE SAME THING KEPT HAPPENING TO ME: I HIT THE BRAKES, THE ABS ENGAGED AND THE CAR STOPPED VERY SLOWLY. IN SOME CASES, IT FELT LIKE THE CAR EVEN ACCELERATED A LITTLE BIT BEFORE FINALLY (AND SLOWLY) COMING TO A STOP. I AM A MECHANICAL ENGINEER AND USED TO WORK FOR GENERAL MOTORS - I HAVE DRIVEN LOTS OF CARS - AND THIS HAS NEVER HAPPENED TO ME BEFORE. I IMMEDIATELY DROVE HOME AND DROVE MY 2002 HONDA CIVIC (WHICH DOES NOT HAVE ANTI-LOCK BRAKES) DOWN THE SAME ROAD. WHILE THE CAR DID SLIDE IN THE SNOW, IT STOPPED IN ABOUT ONE-THIRD THE DISTANCE OF MY PRIUS. THERE IS DEFINITELY SOMETHING THE MATTER WITH THE BRAKING SYSTEM AND/OR THE TRACTION CONTROL SYSTEM WHEN THE ABS ENGAGES. *TR

• 12/30/2009· VEHICLE SPEED CONTROL

  I HAVE OWNED A 2010 PRIUS FOR ABOUT A MONTH, AND HAVE DRIVEN JUST OVER 1000 MILES ON IT. THERE HAVE BEEN THREE SEPARATE INCIDENTS NOW WHERE MY BRAKES HAVE EXPERIENCED A SUDDEN FAILURE WHILE DECELERATING. EACH TIME OCCURRED RIGHT AFTER HITTING A POTHOLE OR A BUMP IN THE ROAD. PASSENGERS IN MY CAR HAVE REPORTED A FEELING OF THE BRAKES "CATCHING" OR "JERKING" WHILE DRIVING ON BUMPY ROADS. THE THREE INCIDENTS I HAVE MENTIONED WERE DURING WINTER AND DURING POSSIBLY ICY CONDITIONS. HOWEVER, I KNOW HOW TO OPERATE A VEHICLE ON ICE, AND I AM AWARE OF HOW ABS BRAKING FEELS. DURING EACH INCIDENT, I WOULD BE BRAKING SLOWLY, WITH PLENTY OF TIME, THEN HIT A BUMP, AND EXPERIENCE A FEELING OF SKIDDING WHILE THE BRAKES DISENGAGED FOR A FEW SECONDS. I ALMOST HIT A PEDESTRIAN AT A TOLL BOOTH, A CONCRETE DIVIDER DURING HIGHWAY DRIVING, AND ANOTHER MOTORIST AT A SUDDEN STOP CONDITION ALONG ANOTHER HIGHWAY. PLEASE INVESTIGATE THESE CARS. I CAN COMPENSATE MY DRIVING SKILLS TO ADJUST FOR ROAD CONDITIONS THAT I AM AWARE OF. IF ANY SUDDEN BRAKING IS REQUIRED, AND I HIT A POTHOLE AT THE RIGHT TIME, I WILL NOT BE ABLE TO STOP. *TR

  ON NOV. 3, 2009, I PURCHASED A PRIUS IV 2010. ON NOV. 10 COMING TO RED LIGHT ON A DRY ROAD. BRAKES GENTLY APPLIED. RIGHT FRONT TIRE HIT A BUMP IN ROAD. CAR SLIGHTLY ACCELERATED BEFORE BRAKES KICKED IN. IT HAS HAPPENED A FEW MORE TIMES SINCE THEN. IN EACH CASE, THE ROAD WAS DRIVE. EVERY TIME WHEN BRAKES ARE APPLIED AND CAR THEN ROLLS OVER A BUMP OR HOLE IN PAVEMENT THIS ACCELERATION OCCURS. LAST TIME WAS ON DEC. 15. EAST HOUSTON IN NYC. COMING TO A LIGHT. BRAKES APPLIED.

I HAVE NEVER HAD THIS HAPPEN ON ANY OTHER CAR THAT I'VE DRIVEN. IT HAPPENS WHEN I HIT A BUMP IN THE REAR. I NOW SEE THAT MANY PEOPLE ARE EXPERIENCING THIS AS I SAW AN ARTICLE ON MSNBC.MSN.COM. I NOW SEE THAT OTHERS ARE EXPERIENCING THE SAME PROBLEM. THIS HAS TO BE INVESTIGATED. THE LAST TIME IT HAPPENED I WAS FACING A CLIFF AND HAD THE CAR NOT STOPPED, MY DAUGHTER AND I WOULD HAVE GONE OFF THE CLIFF AND PROBABLY WOULD HAVE PERISHED. THIS IS ASKING FOR ACCIDENTS TO HAPPEN AND SOMETHING MUST BE DONE TO FIX THIS PROBLEM. THERE ARE WAY TOO MANY OF THESE CARS ON THE ROAD.

I HAVE NOTICED ON SEVERAL OCCASIONS THAT WHEN THE CAR DRIVES OVER A BREAK IN THE PAVEMENT (POTHOLE, OR ROADWORK WHERE THE PAVEMENT HEIGHT DROPS), IT SUDDENLY FEELS "AIRBORNE," AND WILL NOT BRAKE OR SLOW DOWN FOR SEVERAL YARDS, NO MATTER WHAT I DO. I HAVE WORRIED ABOUT NOT BEING ABLE TO STOP AND HITTING A CAR OR A PEDESTRIAN FRONT OF ME, BUT SO FAR EACH TIME MY CAR HAS HAD THIS AIRBORNE-LIKE PROBLEM, I HAVE BEEN FAR ENOUGH AWAY FROM THE CAR OR PERSON IN FRONT OF ME TO STOP. OTHER PEOPLE DRIVING 2010 PRIUS CARS HAVE REPORTED HAVING THE SAME PROBLEM. TOYOTA SHOULD BE REQUIRED TO SOLVE THIS BRAKING ISSUE, AND RECALL THE 2010 PRIUS TO REPAIR THIS PROBLEM. *TR

  The color of my Prius 2010 starts with 070, blizzard white pearl. The body started peeling. I have visited Toyota dealer on 12/29/25 with this issue and got to know that this issue is well known but the service campaign was finished around June, 2025. I own this car from 2023, October and visiting Toyota dealers for services regularly, but never thought that this issue was a common issue by Toyota. Also, I have not heard anything from dealer. It is also true that the issue was not severe and even if it was, I was not attentive to that, apologize for my ignorance. However, it seems the issue is getting worse day by day. I did not receive any notice from Toyota about any campaign about this issue. My Toyota dealer recommended me to reach out to Toyota if any courtesy repair can be done on my vehicle. I reached out to Toyota, but seems to me they cannot do much. Can I get any help in this regards?

  2010 TOYOTA PRIUS BRAKE FAILURE. EVERYTIME WHILE BRAKING IF THERE IS A BUMP OR ON EVEN A SLIGHT BIT OF ICE ON 1 WHEEL ONLY, THE BRAKES WILL RELEASE COMPLETELY AND GO BACK TO ACCELERATING RATHER THAN BRAKING. IT HAPPENS WHEN I EXIT THE HIGHWAY AND THERE IS A CHANGE IN SURFACES FROM TAR TO CONCRETE. IT HAPPENS VERY OFTEN AND CAN HAPPEN ANYTIME. THIS OCCURS AT ANY SPEED FROM 10MPH UP AND I HAVE EXPERIENCED IT FROM 10MPH AND AS HIGH AS 55MPH. THE PROBLEM FIRST OCCURRED AROUND 500 MILES ON THE CAR AND I NOW HAVE OVER 8500 MILES. THIS STARTED IN AUGUST AROUND THE 15TH. I HAVE A 2007 HUMMER H3 AND I HAVE COMPARED THE BRAKING WITH THE SAME CONDITIONS AND SPEEDS AND THE PRIUS IS NOT RESPONDING CORRECTLY. THE HUMMER BRAKES EVEN WITH THE CHANGES. I HAVE ALSO COMPARED ON A 2006 VOLVO S60. THESE BRAKES ARE FAILING AND IT WILL EVENTUALLY RESULT IN A CRASH OR A PEDESTRIAN BEING STRUCK. THERE IS NO PULSING OF THE BREAKS THERE IS ONLY RELEASING FOR ICE OR FOR ANY SURFACE OTHER THAN PERFECT. THERE SHOULD BE SOME TYPE OF REPAIR OR RECALL IMMEDIATELY. I HAVE NOTICED THIS BUT THOUGHT IT WAS ONLY ME UNTIL I SAW THE MSNBC ARTICLE. I WILL NOT LET MY WIFE DRIVE THIS CAR SINCE SHE IS PREGNANT. IT IS NOT SAFE. WHILE SITTING AT TRAFFIC LIGHTS THE TRACTION CONTROL LIGHT KEEPS TURNING ON AND BLINKING AND WILL LOCK THE BRAKES UNTIL THE GAS PEDAL IS PRESSED.

I TOOK IT TO FOUR MECHANICS I SAW THE TOYOTA DEALER AND THEY TOLD ME THAT IT WAS MY BATTERY AND NOW I KNOW THAT I HAVE A RECALL ON IT . I HAVE NOT DRIVEN MY CAR IN THREE MONTHS I'M ALSO STILL PAYING PAYMENTS ON IT . I ALSO WAS TOLD THAT IT WAS MY BREAK. I BOUGHT A NEW BRAKE BOOSTER AND PAY FOR THE REPLACEMENT AND THE PROBLEM WAS STILL HUNGRY JUST

  I APPLIED BRAKE ON A RED LIGHT WHICH IS AS USUAL FOR ME AND I NOTICED CAR DIDN'T SLOW DOWN AND KEPT MOVING PAST THE RED LIGHT. IT HAS HAPPENED BEFORE AND THE IT HAPPENS ON UNEVEN AND EVEN ON MINOR POTHOLES. THE BRAKES ON THE SMALL BUMPS AND MINOR UNEVEN ROADS COMPLETELY LOOSE TRACTION OF THE TIRES AND CAR EVEN FASTER WITH THE BRAKES ON WHEN TRYING TO STOP OVER MINOR UNEVEN ROADS. MECHANIC SAID IT'S OVERSENSITIVE ANTI LOCKING BRAKES THAT CUT OFF THE BRAKE POWER EVEN WHEN IT DETECTS MINOR DISTURBANCE IN THE SENSORS. *TR

  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

  I OWN A 2010 TOYOTA PRIUS, AND LIKE MANY HAVE EXPERIENCED THE BRAKES "CUTTING OUT" WHEN SLOWING DOWN AND GOING OVER A ROUGH SECTION OF ROAD. I DRIVE THROUGHOUT THE HOUSTON, TEXAS AREA AND HAVE HAD THIS ISSUE HAPPEN MANY TIMES, USUALLY UNEXPECTEDLY. THERE ARE A FEW PLACES I DRIVE REGULARLY THAT CREATE THE ISSUE AND I ANTICIPATE THEM AND ADJUST MY DRIVING ACCORDINGLY. *TR
