2010 Toyota Prius complaints

DRIVING MY 2010 PRIUS WHEN SUDDENLY THE AUTO TURNED OFF. INTERIOR LIGHTS CAME ON AND DASH STATED KEY WAS LOCATED WITHIN THE CABIN INDICATING CAR WAS OFF. DEALERSHIP NOTIFIED AND COMPUTER SAW THE ERROR MESSAGE. DEALERSHIP STATED THAT THEY DON'T KNOW WHAT HAPPENED BUT CALL BACK IF IT HAPPENS AGAIN. *TR

I HAVE A 2010 TOYOTA PRIUS. THERE ARE THREE DRIVING MODES: EV, ECO AND POWER. EV IS ALL ELECTRIC, FOR VERY SHORT DISTANCES AT SPEEDS UNDER 25 MPH. EVERY TIME I USE THE EV MODE, AND ACCELERATE PAST 10 (TEN) MILES PER HOUR, THE SYSTEM BEEPS AND THE DISPLAY ALERTS THAT I AM EXCEEDING THE SPEED, AND SHIFTS ONTO ANOTHER MODE. I AM UNABLE TO USE THE EV MODE AS ADVERTISED BY TOYOTA. I HAVE TAKEN THE AUTO TO THE DEALERSHIP AND THEY REFUSE TO ACKNOWLEDGE THE AUTO OPERATES IN FULL ELECTRIC MODE , AT LOW SPEEDS, FOR SHORT DISTANCES. *TR

WHILE DRIVING ON A RESIDENTIAL STREET AT APPROXIMATELY 25 TO 30MPH, I PUT ON BRAKES FOR A SPEED BUMP AND MY 2010 PRIUS LOST BRAKE POWER FOR A (VERY SHORT) PERIOD OF TIME. THIS SAME EVENT HAPPENED ON 3 SEPARATE OCCASIONS FROM NOVEMBER OF 2009 TO THE PAST WEEK. IN ALL CASES THE STREET WAS DRY AND THE CAR WAS TRAVELING AT OR BELOW THE SPEED LIMIT. ONE OCCURRENCE WAS AS DESCRIBED ABOVE AND THE OTHER TWO WE ON SOMEWHAT OF A ROUGH SPOT IN THE ROAD. *TR

I MAY BE ABLE TO HELP WITH YOUR TOYOTA GAS PEDAL PROBLEM. I RENTED A PRIUS OUT IN UTAH A COUPLE OF WEEKS AGO. WHILE TRAVELING THROUGH THE MOUNTAINS, THE CAR SEEMINGLY ACCELERATED UNCONTROLLABLY. I AM A MECHANICAL ENGINEER BY TRADE AND A HABITUAL GEARHEAD. I ALSO DID NOT BUY THE ACCELERATOR STICKING PROBLEM, SO I BEGAN INVESTIGATING THE INCIDENT ON MY OWN. THE SECOND TIME IT HAPPENED, I WAS TRAVELING UP THE SIDE OF A MOUNTAIN IN A NEIGHBORHOOD. THE CAR SUDDENLY LURCHED FORWARD. THE PROBLEM IS ACTUALLY QUITE SIMPLE. THE CRUISE CONTROL IS ATTACHED TO THE STEERING WHEEL AND MOVES WITH THE WHEEL. IF THE CRUISE IS ACTIVATED, SOMETIMES IN A TURN IT IS POSSIBLE TO BUMP THE CRUISE LEVER AND "RESUME" OR "ACCELERATE". DON'T BELIEVE ME - SIT IN ONE AND LOOK FOR YOURSELF. NEED MORE PROOF, HAVE A 6'2" PERSON DRIVE THE CAR AND POSITION THE WHEEL BETWEEN HIS/HER LEGS. I BET YOU AGREE! [XXX] *TR

ON FEB 1, 2010, I WAS APPROACHING A STOP LIGHT INTERSECTION AT ABOUT 7 MPH. WHEN APPLYING THE BRAKES IT WAS LIKE STEPPING ON A SOLID STEEL POLE OR ICE SKATES. THE PEDAL WOULD NOT DEPRESS AND THE BRAKES WOULD NOT ENGAGE. I RELEASED BRAKE PRESSURE AND AGAIN PRESSED THE PEDAL AND THEN THE BRAKES OPERATED SATISFACTORILY. THE STREET WAS SMOOTH ASPHALT, DRY AND IN GOOD CONDITION WITHOUT BUMPS. ON FEB 28, 2010 THE DEALER (LAKE CITY TOYOTA) ACCEPTED THE VEHICLE AND PERFORMED THE "SERVICE CAMPAIGN AOB ABS ACTUATOR ECU UPDATE". *TR

WE HAVE A 2006 TOYOTA PRIUS. EVER SINCE WE BOUGHT IT, WE'VE BEEN EXPERIENCING A PROBLEM WHICH WAS POOH-POOHED BY THE DEALER, BUT NOW WE THOUGHT IT BEST TO REPORT IT. THIS PROBLEM MANIFESTS ITSELF WHEN THE BRAKE IS APPLIED AND WE DRIVE OVER AN UNEVEN SURFACE OR A VERY COMMON IRREGULARITY IN THE PAVEMENT....LIKE WHEN DRIVING OUT OF OUR DRIVEWAY, WHICH INVOLVES A SMALL ELEVATION GRADE CHANGE BETWEEN THE DRIVEWAY AND THE STREET. THE BRAKING ACTION CHANGES SUDDENLY, AND THE CAR SEEMS TO LOOSE BRAKING MOMENTARILY. WE EXPERIENCE THIS AS A LURCH. THIS IS UNEXPECTED, AND WE'VE NEVER HAD A CAR WHICH DID THIS IN OUR 40 YEARS OF DRIVING EXPERIENCE. *TR

2010 PRIUS BRAKE ECU UPDATE DID NOT SOLVE PROBLEM. THIS IS AN UPDATE TO A PRIOR COMPLAINT, REFERENCE # 10300235. THE BRAKES FAILED UNDER THE SAME CIRCUMSTANCES AND EXHIBITED THE SAME BEHAVIOR AS IN THE PREVIOUS COMPLAINT. THE DEALER, HUNTINGTON TOYOTA, ALLEGEDLY UPDATED THE ECU ON 2/24/2010. THE CAR LOSES BRAKING ABILITY BRIEFLY WHILE SLOWING DOWN (BELOW 10 MPH) AND PASSING OVER A ROUGH ROAD SURFACE OR POTHOLE. THE SENSATION IS ONE OF THE CAR SURGING FORWARD. THIS HAS HAPPENED SEVERAL TIME SINCE THE UPGRADE, THE LATEST OCCURRENCE BEING 3/11/2010. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY 20 MPH AND APPROACHING A TRAFFIC LIGHT, HE PLACED HIS FOOT ON THE BRAKE PEDAL. THE VEHICLE THEN ABNORMALLY ACCELERATED AS HE TRAVELED OVER A POT HOLE. UPON CONTACTING THE DEALER, HE WAS ADVISED THAT HE WOULD HAVE TO WAIT UNTIL HE RECEIVED RECALL NOTIFICATION FROM THE MANUFACTURER BEFORE MAKING ANY REPAIRS TO THE VEHICLE. THE VIN WAS NOT AVAILABLE. THE APPROXIMATE FAILURE MILEAGE WAS 4,000 AND THE CURRENT WAS 4,200.

PURCHASED 2010 PRIUS ON AUG LL,09. HAVE RETURNED TO DEALER 5 TIMES, BEGINNING ON SEPT.29, 09, TO REPORT SAME PROBLEM...WHICH IS THAT AT RANDOM TIMES WHEN I SHIFT FROM "P" TO EITHER "D" OR "R", THE VEHICLE LUNGES AND WHEN I APPLY THE BRAKE, IT IS LIKE HITTING A BRICK WALL. THIS PROCESS IS REPEATED SEVERAL TIMES IN SEQUENCE...LUNGE, BRAKE, LUNGE, BRAKE..THEN IT CORRECTS ITSELF AND DRIVES NORMALLY. I CANNOT PREDICT WHEN THIS WILL OCCUR, SOMETIMES IT IS WEEKS AND HUNDREDS OF MILES BETWEEN OCCURRENCES; SOMETIMES ONLY A FEW MILES AND HOURS BETWEEN INCIDENTS. THE DEALER ALWAYS SAYS THEY HAVE NOT BEEN ABLE TO REPRODUCE THE PROBLEM, THEREFORE NO DIAGNOSIS OR REPAIR. I HAVE REPORTED TO TOYOTA CUSTOMER SER. AND WAS ASSIGNED A CASE #. HAVE HAD ONGOING CONVERSATION WITH TCS REP TO REPORT THIS AND SEVERAL OTHER PROBLEMS, I.E. VARIOUS WARNING LIGHTS AT INAPPROPRIATE TIMES..."KEY DETECTED IN VEHICLE" WHILE DRIVING DOWN THE ROAD... ETC. AM ALWAYS TOLD "SCAN SHOWS NO PROBLEMS". I THINK THERE IS A PROBLEM WITH ELECTRONICS. UNSAFE, FRIGHTENING. LATEST INCIDENT ON 3/05/10. DEALER INSTALLED SOFTWARE FIX FOR BRAKE RECALL ON 2/10/10. AT TIMES MUST REPEATEDLY MOVE GEAR SHIFT LEVER BEFORE IT RESPONDS. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. HE STATED WHEN DRIVING OVER UNEVEN ROAD SURFACES OR SPEED BUMPS IN THE ROAD THE VEHICLE WOULD MOMENTARILY LOSE BRAKING POWER. ALSO, WHEN DEPRESSING THE BRAKE PEDAL OVER ANY TYPE OF UNEVEN ROAD SURFACE THE VEHICLE WOULD SURGE MOMENTARILY. THE DEALER WAS CONTACTED AND INFORMED THE CONTACT THAT THERE WAS NOTHING WRONG WITH THE VEHICLE. THE FAILURE PERSISTED AND THE DEALER WAS CONTACTED A SECOND TIME WHERE THE CONTACT WAS INFORMED THAT THEY WERE AWARE OF THE ISSUE, HOWEVER DID NOT HAVE AN EXPLANATION OR A REMEDY FOR THE FAILURE. THE FAILURE PERSISTED AND THE DEALERSHIP WAS CONTACTED A THIRD TIME WHERE THE CONTACT WAS ADVISED THERE WAS AN OPEN RECALL ON THE VEHICLE NHTSA RECALL NUMBER: 10V039000:SERVICE BRAKES, AIR:ANTILOCK:CONTROL UNIT/MODULE) AND TO BRING THE VEHICLE IN TO PERFORM THE RECALL SERVICE. AFTER RECALL REPAIRS WERE PERFORMED ON THE VEHICLE, THE CONTACT EXPERIENCED THE EXACT SAME FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 1,000 AND THE CURRENT IS 7600.

2010 TOYOTA PRIUS GAVE ME IN TWO DIFFERENT OCCASIONS THE FEELING THAT THE BRAKE WAS NOT WORKING. IN BOTH CASES I WAS DRIVING SLOW AND TRACTION CONTROL LIGHT CAME ON. IN ONE CASE I WAS BACKING UP FROM MY GARAGE; IN THE OTHER CASE I WAS TRANSITIONING FROM A SMALL DOWNHILL EXIT TO A FLAT STREET. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING 10 MPH OVER RAILROAD TRACKS, WITH HER FOOT OFF OF THE ACCELERATOR PEDAL, SHE NOTICED THAT THE VEHICLE SUDDENLY BEGAN TO ACCELERATE WITHOUT DRIVER INTENT. SHE IMMEDIATELY DEPRESSED THE BRAKE PEDAL AND THE VEHICLE MOMENTARILY DECREASED IN SPEED, HOWEVER THE VEHICLE SOON BEGAN TO ACCELERATE AGAIN. SHE THEN PUT THE VEHICLE IN NEUTRAL AND SHUT THE ENGINE OFF. SHE WAS ABLE TO STOP THE VEHICLE AND WITHIN A FEW MINUTES, RESTARTED THE ENGINE. THE VEHICLE BEGAN TO FUNCTION NORMAL. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS TEST DRIVEN. THE DEALER FOUND NOTHING WRONG WITH THE VEHICLE AND COULD NOT DUPLICATE THE FAILURE. THE CONTACT STATED THAT SHE HAD EXPERIENCED THE UNINTENDED ACCELERATION OVER 12 TIMES. THERE WERE NO REPAIRS MADE TO THE VEHICLE. THE FAILURE MILEAGE WAS 4,000 AND THE CURRENT MILEAGE WAS 8,352.

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT WAS DRIVING APPROXIMATELY 35 MPH, PROCEEDING TO MAKE A TURN. THE BRAKE PEDAL WAS DEPRESSED AND THE VEHICLE SURGED FORWARD WITH A LOUD NOISE. THE CONTACT WAS ABLE TO SLOW THE VEHICLE DOWN. THE CONTACT WILL NOT DRIVE THE VEHICLE DUE TO THE POTENTIAL SAFETY HAZARD. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER. THE VEHICLE WAS NOT REPAIRED FOR THE MALFUNCTION. THE FAILURE MILEAGE WAS 6,000. THE CURRENT MILEAGE WAS 10,000.

TODAY I DROVE THE CAR TO SEE WHAT WOULD HAPPEN IF THE CAR WAS ACCELERATING AND I WANTED TO STOP IT OTHER THAN PUTTING ON THE BRAKES AND HITTING THE PARK BUTTON. I WAS TRYING TO REPRODUCE THE CONDITIONS WHICH HAVE RESULTED IN NUMEROUS ACCIDENTS AND MORE THAN ONE LIFE. WHILE SLIGHTLY ACCELERATING I FIRST TRIED TO STOP THE CAR BY PRESSING THE POWER BUTTON. THIS DID NOTHING. I THEN PRESSED THE BRAKE PEDAL ON THE LEFT SIDE WHICH IS YOUR HAND BRAKE, HARD UNTIL THE BRAKE LIGHT CAME ON AND THE ALARM SOUNDED. IN SPITE OF THIS THE CAR KEPT GOING! THE ONLY WAY I COULD STOP THE CAR WAS BY STOPPING THE CAR WITH THE FOOT BRAKE AND THEN PRESSING THE PARK BUTTON. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY 30 MPH THE BRAKES WERE ENGAGED WITH A SLOW POWER RESPONSE. THE VEHICLE HAD A PRIOR RECALL REPAIR UNDER NHTSA CAMPAIGN ID NUMBER 10V039000 (SERVICE BRAKES, AIR: ANTILOCK: CONTROL UNIT/MODULE). THE FAILURE OCCURRED INTERMITTENTLY. THE FAILURE MILEAGE WAS 10,000. THE CURRENT MILEAGE WAS 10,600.

I HAVE A 2010 PRIUS. MY CAR WAS SURGING BEFORE BRAKING ON BUMPY TERRAIN. I BROUGHT THE CAR IN FOR REPAIR TO THE DEALER, AS PER THE RECALL. THE PROBLEM IS STILL PRESENT. I STILL FEEL A SURGE WHILE BRAKING OVER BUMPS. I CONTACTED THE SERVICE DEPARTMENT OF TOYOTA AND WAS TOLD THERE WAS NOTHING THEY COULD DO TO FIX THE PROBLEM AND SUGGESTED I CALL TOYOTA HEADQUARTERS IN CALIFORNIA. I HAVE ATTEMPTED THREE TIMES TO REPORT MY COMPLAINT AND ON EACH OCCASION WAITED ON THE PHONE OVER A HALF HOUR WITH NO ANSWER. *TR

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 BRAKES FAILED MOMENTARILY TWICE WHILE GOING OVER RUTS IN THE ROAD; I WAS ABLE TO KEEP CONTROL OF THE CAR AND THE BRAKES RESUMED WORKING RIGHT AFTERWARDS. *TR

I HAD A BRAKING ISSUE, THE CAR WOULD NOT BRAKE AFTER HITTING SEVERAL POTHOLES AND GOING INTO AN INTERSECTION. THIS IS POST RECALL. THE RECALL WAS PERFORMED BY TOYOTA THREE WEEKS AGO. THIS IS THE THIRD INCIDENT FOR THIS VEHICLE WITH IDENTICAL SYMPTOMS. AFTER COASTING FOR 10 FEET OR SO, THE VEHICLE DID APPLY THE BRAKES. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHENEVER THE CONTACT ATTEMPTS TO BRAKE WHILE TRAVELING OVER A ROUGH SURFACE THE BRAKES WILL HESITATE TO ENGAGE INCREASING THE STOPPING DISTANCE. PRIOR TO THE RECENT FAILURE THE CONTACT HAD TAKEN HER VEHICLE TO THE DEALERSHIP WHERE NHTSA RECALL # 10V039000 WAS PERFORMED ON HER VEHICLE. THE CURRENT AND FAILURE MILEAGES WERE 1300. UPDATED 05/10/10 *BF UPDATED 05/10/10*JB

I OWN A 2010 PRIUS. I HAVE OWNED THE CAR SINCE OCT 2009. TWICE I LET THE CAR SIT IN MY GARAGE WITHOUT DRIVING IT FOR 6 DAYS. THE BATTERY COMPLETELY DISCHARGE OVER THE 6 DAYS SUCH THAT THE CAR HAS TO BE JUMPED IN ORDER FOR IT TO START. BOTH TIMES I TOOK THE CAR TO TOYOTA SERVICE CENTER AND BOTH TIMES THEY DID NOT FIND ANYTHING WRONG WITH THE CAR. THERE SOLUTION WAS TO NOT LET THE CAR SIT UNDRIVEN FOR THAT LONG. HOWEVER, IF I TOOK THE CAR TO THE AIRPORT AND LEFT IT WHILE I WAS GONE FOR A WEEK, IT WOULD NOT START WHEN I RETURN. THIS IS NOT ACCEPTABLE TO ME SINCE I TRAVEL A LOT. ACCORDING TO TOYOTA I HAVE NO RECOURSE. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT WAS DRIVING APPROXIMATELY BETWEEN 50-55 MPH ON A SNOW COVERED ROAD SURFACE, WHILE BRAKING THE VEHICLE SUDDENLY SURGED FORWARD UNEXPECTEDLY. THE DRIVER WAS UNABLE TO CONTROL THE VEHICLE AND CRASHED INTO A DITCH. THERE WERE NO INJURIES. A POLICE REPORT WAS FILED FOR THE INCIDENT AND THE VEHICLE WAS ABLE TO RESUME NORMAL OPERATION. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC FOR THE FRONT END DAMAGE. THE MANUFACTURER WAS NOTIFIED AND REQUESTED THAT THE VEHICLE NOT BE REPAIRED UNTIL A ENGINEER INSPECTED IT. THE VEHICLE HAS NOT BEEN REPAIRED AT THIS TIME. THE CURRENT AND FAILURE MILEAGES WERE 11,000.

MY 2010 PRIUS HAS HAD THESE PROBLEMS, WHICH ARE NOT BEING ADDRESSED BY TOYOTA. 1)GAS PEDAL STOPPED WORKING AT ALL ON TWO OCCASIONS GOING 20-30 MILES AN HOUR. HAD TO PULL OVER, TURN CAR OFF, RESTART IT. THEN IT WORKED. HASN'T HAPPENED AGAIN. 2)CRUISE CONTROL IS VERY DIFFICULT TO STOP WITH BRAKE. THIS IS CONSISTENT. I HAVE STOPPED USING THE CRUISE CONTROL BECAUSE IT HAS ALMOST CAUSED ME TO REAR END ANOTHER VEHICLE ON SEVERAL OCCASIONS. *TR

2010 PRIUS -ALREADY HAD THE BRAKE SOFTWARE FIX -CONTINUES TO ACCELERATE SLIGHTLY WHEN IT GOES OVER POTHOLES WITH THE BRAKE PEDAL DEPRESSED - USUALLY LOW SPEED. *TR

WHEN BRAKING, ALL OF A SUDDEN THE CAR LURCHES FOR A SECOND OR SO, AS IF ON ICE. THIS HAPPENED 3 TIMES IN DIFFERENT CIRCUMSTANCES, ONCE NOT RELATED TO A POTHOLE. TOYOTA DEALER IN AVON CT APPLIED THE CORRECTION TO THE SOFTWARE, AND THE NEXT WEEK (LAST WEEK) THE SAME THING HAPPENED AGAIN, WHEN I HIT A WIDE, BUT NOT DEEP POTHOLE WHILE BRAKING, JUST BEFORE STOPPING AT THE END OF A HIGHWAY EXIT RAMP. IN THIS SITUATION, IT WAS FORTUNATE THAT NO CAR WAS IN FRONT OF ME AT THE LIGHT. ADDITIONALLY I HAD A PROBLEM WITH SUDDEN ACCELERATION A COUPLE TIMES WHEN DRIVING AT SLOW SPEED. *TR

THERE ARE SEVERAL PROBLEMS I'VE EXPERIENCED WITH THE 2010 TOYOTA PRIUS PURCHASED NEW 10 DECEMBER 2009. 1. WHEN USING CRUISE CONTROL: ~ THERE'S REGULARLY WHAT FEELS LIKE AN ENGINE SURGE WHEN THE FOOT BRAKE IS APPLIED TO TURN OFF CRUISE CONTROL. THIS HAPPENS REGULARLY, INCLUDING ON SMOOTH, LEVEL, DRY ROADWAYS AND FREEWAYS AND AT SPEED SETTINGS FROM 45 TO 60 MPH. BECAUSE OF CONCERN ABOUT THIS I NOW MANUALLY TURN OFF CRUISE CONTROL. THREE DAYS AGO THE CAR WAS TEST DRIVEN BY A TOYOTA DEALERSHIP SERVICE DEPARTMENT EMPLOYEE, WHO REPORTED USING CRUISE CONTROL 6 TIMES AND TURNING CRUISE CONTROL OFF BY APPLYING THE FOOT BRAKE; THE REPORT WAS 'CRUISE CONTROL SHUT OFF IMMEDIATELY WHEN ENOUGH PRESSURE APPLIED [EMPHASIS ADDED] TO PEDAL.' ~ ON SATURDAY, FEBRUARY 27, 2010 AFTER THE CAR HAD BEEN SET AT 60 IN CRUISE CONTROL FOR SOME TIME THERE WAS A STRONG ODOR (LIKE A CAR BEING DRIVEN WITH THE "HAND" BRAKE ON, BUT MY CAR'S WASN'T ENGAGED) WHILE ON A DRY FREEWAY DOWNGRADE (GRADUAL, NOT STEEP). I TURNED OFF THE CRUISE CONTROL, CONTINUED AT THE SAME SPEED AND THE ODOR STOPPED. THIS WAS THE FIRST SUCH OCCURRENCE. I'VE USED CRUISE CONTROL REGULARLY BECAUSE OF USUALLY DRIVING ON FREEWAYS 6 DAYS/WEEK. THE TOYOTA SERVICE DEPARTMENT'S TEST DRIVE THREE DAYS AGO REPORTED 'NOT EVIDENT.' 2. SHIFTING FROM PARK TO DRIVE SEVERAL TIMES THIS SHIFTING WAS SUCCESSFUL ONLY AFTER MULTIPLE TRIES. ON ONE RECENT OCCASION AFTER SEVERAL TRIES AND ALSO TURNING THE CAR OFF, ON AGAIN, AND THEN UNSUCCESSFULLY RETRYING, I R

ON FRIDAY 2/26 AT ~ 1:15PM, I WAS DRIVING MY 2010 PRIUS. IT WAS RAINING HARD OUTSIDE. AS I PUT ON BRAKES, THE CAR SEEMED TO ACCELERATE / DID NOT BRAKE AND DROVE INTO A PARKING LOT CURB. DAMAGE WAS DONE TO THE FRONT END OF THE CAR. THERE HAVE BEEN MULTIPLE OCCASIONS DURING WHICH MY HUSBAND AND I HAVE SEPARATELY NOTICED THIS SAME TYPE OF ACCELERATION / FAILURE TO BRAKE - PARTICULARLY WHEN DRIVING IN THE RAIN, DOWN A HILL, OR OVER AN UNEVEN SURFACE (LIKE A POTHOLE). NONE OF THESE OTHER OCCASIONS HAVE RESULTED IN ANY INJURY OR DAMAGE. FOLLOWING THE 2/26/2010 INCIDENT, I CONTACTED TOYOTA THAT SAME DAY. I WAS TOLD THAT A CUSTOMER RELATIONS MANAGER WOULD CALL ME BACK BY TUESDAY 3/2. DID NOT HEAR BACK. ON WEDNESDAY 3/3 I CALLED TO FOLLOW UP. AFTER BEING ON HOLD FOR 1 HOUR, I GAVE UP. SENT AN E-MAIL TO CUSTOMER SERVICE ADVISING OF THE SITUATION. STILL DID NOT HEAR BACK. ON SATURDAY 3/6 I CALLED AGAIN. WAS AGAIN ON HOLD X 1 HOUR AND TOLD CUSTOMER SERVICE REPRESENTATIVE OF WHAT HAPPENED - THEY APOLOGIZED AND SAID THEY DID NOT HAVE MY CONTACT INFORMATION. WAS TOLD I WOULD GET A CALL BACK BY 3/9. DID FINALLY SPEAK WITH AN AGENT ON 3/8 WHO NOW TELLS ME THAT I WILL GET A CALL WITHIN 10 DAYS. AT THAT TIME, I WILL BE OFFERED AN INSPECTION APPOINTMENT WITHIN THE FOLLOWING 30 DAYS. AND, WITHIN 30 DAYS AFTER THE APPOINTMENT I WILL RECEIVE WRITTEN NOTIFICATION OF THE OUTCOME OF THE INSPECTION. I FEEL UNSAFE DRIVING MY CAR. I WOULD HOPE FOR A FASTER RESOLUTION TO THIS SITUATION. I WOULD LIKE FOR T

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT TOOK THE VEHICLE TO AN AUTHORIZED DEALER TO HAVE THE RECALL REPAIR PERFORMED; HOWEVER, THE TURN SIGNALS BEGAN ACTIVATING ON THEIR OWN AFTER THE REPAIR WAS MADE. THE WARNING INDICATOR ILLUMINATED WHICH INDICATED THAT THE VEHICLE WAS IN DANGER OR THE FRONT WHEELS WERE GOING TO SPIN OUT OF CONTROL. THERE WAS ALSO A VERY LOUD BUZZING INDICATOR THAT STARTLED THE CONTACT WHILE HE WAS DRIVING. THE DEALER WAS INFORMED ABOUT THE FAILURE AND ADVISED THE CONTACT NOT TO DRIVE THE VEHICLE. THE CONTACT HAS NOT SPOKEN WITH THE MANUFACTURER . THE VEHICLE HAS NOT BEEN REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 400 AND THE CURRENT MILEAGE WAS 435. UPDATED 04/21/10

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. SHE CONFIRMED SHE HAS EXPERIENCED BRAKE FAILURE SEVERAL TIMES IN THE VEHICLE. WHILE ATTEMPTING A RIGHT TURN OVER RAILROAD TRACKS WITH HER FOOT ON THE BRAKE PEDAL, THE VEHICLE ABNORMALLY LUNGED FORWARD AND BEGAN TO ACCELERATE. SHE CONTINUED TO DEPRESS THE BRAKE PEDAL UNTIL THE VEHICLE CAME TO A STOP. SHE ALSO NOTICED THAT WHEN DRIVING UPHILL, THE VEHICLE WAS HESITANT TO ACCELERATE. THE VEHICLE HAD NOT YET BEEN TAKEN TO THE DEALER FOR INSPECTION. THE FAILURE MILEAGE WAS 65,000 AND THE CURRENT WAS 96,077.

A SAFETY RECALL PROCEDURE PERFORMED RECENTLY ON THE 2010 PRIUS TO FIX THE LURCHING BRAKES HAS NOT BEEN WORKING OUT. I HAD IT DONE RECENTLY, AND THIS IS PAST THE RECALL. IN MORE THAN 3 OCCASIONS RECENTLY I ALMOST HIT THE CAR IN FRONT OF ME WHILE GOING OVER A MANHOLE STOPPING OVER FOR A SIGNAL GOING AS LOW AS 25MPH. THE CAR JUMPED FORWARD DESPITE MY NORMAL BRAKING TO GET IT TO STOP, FORCING ME TO BRAKE HARD COMING TO A FORCED STOP. I AM AFRAID SOMEDAY I MAY NOT BE SO LUCKY !! WISH, TOYOTA PUT MORE THOUGHT INTO THEIR SOLUTIONS THAN RUSHING INTO THE MARKET WITH SUB STD. PROCEDURES & CARS !! *TR

I HAVE OWNED 4 TOYOTA PRIUS HYBRID VEHICLES (2005, 2007, 2008, 2010). I EXPERIENCED A SLIGHT FEELING OF ACCELERATION SOMETIMES WHEN DEPRESSING THE GAS PEDAL IN THE 07 AND 08 MODELS. I ALSO FELT A SLIGHT SURGE SOMETIMES WHEN BRAKING. WHEN I ASKED THE TOYOTA MECHANIC ABOUT THIS I WAS TOLD THAT STORED ENERGY FROM THE HYBRID SYSTEM WAS BEING EXPELLED. I NEVER THOUGHT IT MIGHT BE A SAFETY ISSUE BECAUSE OF WHAT HE SAID. NOW I DRIVE THE 2010 PRIUS, HAD THE BRAKE RECALL DONE LAST WEEK AND A COUPLE DAYS LATER, WHEN DRIVING OVER 3 SLIGHT BUMPS WHEN ENTERING A PARKING LOT, I FELT THAT SAME SLIGHT ACCELERATION. PLEASE CONTINUE DEMANDING TOYOTA FIX THIS DANGEROUS PROBLEM. PLEASE TALK TO THE US CONGRESS ABOUT INVESTIGATING THESE CARS BEFORE THERE ARE MORE ACCIDENTS. I THINK THE 2010 PRIUS ALSO HAS ISSUES WITH ACCELERATION AS WELL AS BRAKING BECAUSE I HAVE EXPERIENCED WHAT I DESCRIBED IN THE 07, 08, 10 MODELS. *TR

2010 PRIUS 3 TIMES I HAVE THE BRAKES GRAB AND LOCKED SEVERAL TIMES IN A ROW WHEN I HAVE BEEN APPLYING VERY SLOW PRESSURE. TWICE WHILE BACKING OUT FROM PARKING SPACE AND ONCE WHILE GOING FORWARD SLOWLY IN MY DRIVEWAY. THEY THEN BEGAN ACTING NORMALLY. I AM CONCERNED THAT THIS COULD HAPPEN IN TRAFFIC CAUSING AN ACCIDENT. I CAN'T FIND A PLACE AT TOYOTA TO REPORT. I WAS IN AN ACCIDENT WITH 2002 TOYOTA PRIUS WITH UNEXPLAINED ACCELERATION IN OCTOBER 2009-ALREADY REPORTED. *TR

BRAKE PROBLEM WITH 2010 PRIUS. I WAS CROSSING A POTHOLE ON STREET AND PUT THE BRAKE ON BEFORE THE FRONT WHEELS GET INTO THERE. WHILE THE FRONT WHEELS ENTER THE HOLE, I FELT MY CAR SUDDENLY LOST BRAKING AND SPEED UP. IT LASTED FOR LESS THAN 1 SEC. I GUESS. THEN, EVERYTHING WAS NORMAL. *TR

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

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE DRIVER STATED THE HER VEHICLE WAS RECENTLY REPAIRED PER THE VEHICLE SPEED CONTROL RECALL. THE FAILURE CONTINUED TO OCCUR. IMMEDIATELY AFTER THE REPAIR WAS MADE, SHE WAS DRIVING 30 MPH OVER A POTHOLE; HOWEVER, WHEN SHE ENGAGED THE BRAKE PEDAL, THE VEHICLE ACCELERATED. THE VIN WAS NOT AVAILABLE. THE FAILURE MILEAGE WAS 10,500 AND THE CURRENT MILEAGE WAS 11,000.

INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). I LEFT A MESSAGE ON YOUR VOICE MAIL. I HAVE A 2010 PRIUS. I CALLED MY DEALERSHIP THIS AM WITH CONCERN ABOUT THE INCIDENT LAST NIGHT WITH THE GAS PEDAL. THE GENTLEMAN THAT SPOKE TO ME WAS VERY ARROGANT STATING "I DON'T KNOW WHAT EVERYONE IS SO WORRIED ABOUT, ALL HE HAD TO DO WAS PUT IT IN NEUTRAL". I ASKED HIM TO STAY ON THE PHONE WITH ME WHILE I DID A TEST RUN IN MY CAR. I GOT IN THE CAR (WITH HIM ON THE PHONE) STARTED DRIVING AND PUT MY FOOT ON THE BRAKE AND PUSHED THE JOY STICK TO NEUTRAL, NOTHING HAPPENED, THE CAR REMAINED IN DRIVE. I PROCEEDED TO DO THIS 13 TIMES WITH THE DEALERSHIP ON THE PHONE, IT ONLY ENGAGED IN NEUTRAL 2 TIMES OUT OF THE 13. I WAS GETTING UPSET AND VOICING MY CONCERN. I ASKED IF I COULD BRING IT IN AND HAVE IT CHECKED OUT. THE DEALERSHIP SAID TO ME "SURE YOU CAN BRING IT IN BUT I DON'T KNOW WHAT I CAN DO ABOUT IT". I WAS FURIOUS, I CALLED THE LOCAL CHANNEL 3 AND THEY CAME OUT AND DID A STORY ON IT. WE DROVE THE CAR AROUND AND I PUT IT IN NEUTRAL PROBABLY AT LEAST 30-50 TIMES AND IT DID NOT ENGAGE 90% OF THE TIME. I TRIED CALLING TOYOTA HEADQUARTERS AND THEY ARE NOT TAKING ANY CALLS AT THIS TIME, THIS WAS A QUOTE AND ANIMATED, YOU CANNOT TALK TO A REAL PERSON. I DON'T WANT THE CAR, I AM AFRAID TO DRIVE IT.

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT WAS DRIVING APPROXIMATELY 20 MPH WITH THE BRAKE ENGAGED WHEN THE VEHICLE ACCELERATED. THE CONTACT CRASHED INTO THE REAR END OF A NISSAN. THE WEATHER WAS NOT A FACTOR. THE CONTACT OBSERVED SMOKE COMING FROM THE VEHICLE. THE REAR SUSPENSION WAS DAMAGED AFTER THE CRASH OCCURRED. THE INSURANCE COMPANY AUTHORIZED THE VEHICLE TO BE TOWED TO AN IMPOUND LOT. THE VIN WAS NOT AVAILABLE. THE APPROXIMATE FAILURE AND CURRENT MILEAGES WERE 36,000.

I JUST PICKED UP MY 2010 TOYOTA PRIUS FROM THE DEALERSHIP FOR THE SECOND TIME SINCE THE BRAKE RECALL. THIS IS THE THIRD TIME MY PRIUS HAS BEEN IN FOR SERVICE ON MY BRAKES. THEY PERFORMED THE RECALL AND KEEP TELLING ME THAT MY CAR IS FUNCTIONING PROPERLY AND THAT ALL HYBRIDS BRAKE THIS WAY. I WILL ADMIT MY PRIUS STOPS QUICKER THAN BEFORE THAN THE RECALL HOWEVER I STILL NOTICE THAT IT SURGES FORWARD BEFORE THE CARE STOPS AT TIMES. IN THE 2 WEEKS I HAD THE CAR BACK AFTER THEY PERFORMED THE RECALL I AND MY HUSBAND NOTICED THAT THE BRAKES STILL SURGED FORWARD BEFORE STOPPING. I PICKED UP MY CAR TODAY AND I NOTICED IT AGAIN ON MY WAY HOME. WHAT IS IT GOING TO TAKE TO GET THIS CAR FIXED PROPERLY? I DO NOT FEEL SAFE DRIVING IT AROUND, AND I HAVE YOUNG CHILDREN. I WANT SOMEONE TO LOOK INTO WHY THESE RECALLS ARE MAKING THE PROBLEM ALITTLE BETTER BUT NOT FIXING THE PROBLEM. IF TOYOTA DOES NOT KNOW HOW TO FIX IT THEN MAYBE THEY NEED TO BUY THESE UNRELIABLE DEATH TRAPS BACK FROM THEIR CONSUMERS AND STOP FEEDING US A LINE ABOUT HOW THIS IS NORMAL AND ALL HYBRIDS DO THIS. *TR

2010 TOYOTA PRIUS - I WAS DRIVING MY 2010 TOYOTA PRIUS FOR A SHORT PERIOD AS A COMPANY CAR. I NOTICED THAT WHEN THE BATTERY GOT LOW WHILE IN PARK THE ENGINE WOULD KICK IN TO RECHARGE THE BATTERY. THE ENGINE WOULD CAUSE THE CAR TO SLIGHTLY JERK FORWARD OR BACK WHICH WOULD BE EXPECTED BY THE FORCE OF THE ENGINE THRUST. WHAT WAS STRANGE IS THAT WHEN I WAS CROSSING THE STREET AFTER COMING OUT OF AN OIL CHANGE, MY FOOT WAS ON THE BRAKE WAITING FOR TRAFFIC TO CLEAR ONLY TO HAVE THE ENGINE KICK IN AND SLIGHTLY JERK THE CAR FORWARD. IT SURPRISED ME! LIKE I SAID MY FOOT WAS ON THE BRAKE AND KEPT THE CAR FROM MOVING. I VISITED THE TOYOTA DEALERSHIP TO DISCUSS AND EMAILED TOYOTA TO MAKE THEM AWARE OF IT. AFTER HEARING MORE NEWS ABOUT TOYOTA I FELT I NEEDED TO SHARE THIS INFORMATION. I NO LONGER HAVE THE CAR BECAUSE I DID NOT FEEL SAFE, WITH ALL OF THE PROBLEMS WITH TOYOTA, SO I TURNED IT BACK IN TO MY FLEET WHO MANAGES THE COMPANY CARS. I HAVE ALSO NOTICED A WINDING SOUND IN THE STEERING WHEEL WHEN IT IS TURNING. I CANNOT RECALL THE EXACT DATE OF THE INCIDENT SO I HAVE MENTIONED FEB 19 2010 AS THE APPROXIMATE DATE. IF YOU NEED AN EXACT DATE PLEASE CONTACT ME SINCE I CAN GO TO THE SITE WHERE I GOT MY OIL CHANGE AND LOOK UP MY RECORDS TO PROVIDE AN EXACT DATE. *TR

TOYOTA VEHICLES IN ALL OF THE INFORMATION I HAVE READ, TOYOTA NOR THE DEPARTMENT OF TRANSPORTATION HAS INFORMED DRIVERS TO SHIFT THE VEHICLE TO NEUTRAL WHEN IT ACCELERATING BY ITSELF. BY SHIFTING THE TRANSMISSION TO NEUTRAL IT SHOULD ALLOW THE DRIVER TO BRING THE VEHICLE TO A SAFE STOP. *TR

I VISITED MY LOCAL DEALERSHIP FOR REPAIR OF THE BRAKE RECALL OF THE 2010 PRIUS IN EARLY FEBRUARY. I DO NOT BELIEVE THAT THIS REPAIR HAS FIXED THE PROBLEM. A FEW DAYS AFTER THE FIX, MY CAR SEEMED TO ACCELERATE AS I WAS BRAKING AND HAPPENED TO BE GOING OVER A POT HOLE. THEN AGAIN JUST A FEW DAYS AGO, I WAS BRAKING TO MAKE A TURN AND HIT A VERY ROUGH PATCH OF ROAD. MY CAR AGAIN NOTICEABLY SEEMED TO ACCELERATE EVEN THOUGH I WAS BRAKING. *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

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

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 FEE

MY 2010 TOYOTA PRIUS WILL SOMETIMES BRAKES VERY HARD UNDER LIGHT BRAKE PEDAL PRESSURE WHEN BACKING UP. IT HAPPENS EVERY 2 TO 3 DAYS AND CAN BE WHEN THE CAR IS HOT AND JUST DRIVEN, OR COLD AND BEEN PARKED FOR HOURS. WHEN THIS OCCURS,IT WILL CONTINUE TO HAPPEN NO MATTER HOW MANY TIMES THE BRAKES ARE APPLIED IN REVERSE, WITH THE LIGHTEST OF BRAKE PRESSURE, THE BRAKE APPLY VERY HARD. THEN AFTER THE EVENT, SAY A MILE OR TWO LATER, WHEN BACKING UP, THE BRAKE WILL ACT NORMALLY TO THE BRAKE PEDAL PRESSURE EXERTED. *TR

HAVING NOTICED AN APPARENT BRAKING LAG ON SEVERAL OCCASION WITH OUR 2010 PRIUS ON TUESDAY 02 OF 2010 I WAS COMING UP TO A STOP SIGN ABOUT A MILE FROM OUR HOME ON A COUNTRY ROAD. I STARTED STOPPING QUIT SOME DISTANCE FROM THE CORNER STOP SIGN AND OBSERVING THE DASH DISPLAY SHOWING THE POWER USAGE OF THE PRIUS TO TRY AND GET A INDICATION OF HOW MANY SECONDS OF LAG BETWEEN THE REGENERATED BRAKING BEFORE THE ELECTRIC HYDRAULIC BRAKES I COULD EXPECT. WHILE WATCHING THE DISPLAY, WITH MY RIGHT FOOT ON THE BRAKE WHILE APPLYING LIGHT BRAKING PRESSURE TO THE BRAKE PEDAL ONLY I NOTICED THAT WHEN THE DISPLAY SHOWED REGENERATING BRAKING STOPPED. I WAS DOING LESS THEN 10 MILE PER HOUR APPROXIMATELY I EXPERIENCED A LOSS OF BRAKING AS BEFORE BUT ALSO NOTICED THAT THE DISPLAY NOW SHOWED POWER BEING APPLIED FROM THE BATTERY TO THE ELECTRIC DRIVE MOTOR AND TO THE DRIVE WHEELS. I PUSH HARD ON THE BRAKES AND THE CAR CAME TO A STOP IN TIME THE DISPLAY SHOWED WHEN I APPLIED THE BRAKE HARD THAT THE POWER STOPPED BEING DELIVERED TO THE WHEELS THIS TIME AND AFTER STOPPING THE DISPLAY SHOWED THE DRIVE WHEELS STOPPED ROTATION AS USUAL. THIS ROAD WAS NOT BUMP AND RELATIVELY SMOOTH THE FULL LENGTH OF THE ROAD HAVING BEEN RESURFACED SEVERAL YEARS AGO. I THINK THERE MAY BE ANOTHER PROBLEM OTHER THEN THE ONE BEING REPORTED AS BRAKE LAG BY THE COMPANY. IT ALSO SEEMS TO BE INTERMENT WHEN IT HITS AND DURATION OF LOSS OF BRAKING. I HOPE THIS MAY SHED SOME LIGHT ON WHAT THERE PROBLEM IS. *TR

I HAVE A 2010 PRIUS WHICH I TOOK TO CHAMPION TOYOTA IN HOUSTON FOR THE RECALL REPAIR ON FEBRUARY 12. ACCORDING TO THEM THEY PERFORMED THE BRAKE RECALL SOFTWARE REPAIR. HOWEVER, ON 3/3 WHEN I WAS DRIVING HOME FROM WORK I EXPERIENCED THE BRAKE FAILURE PROBLEM AGAIN. *TR

WHEN BACKING UP, THE CAR WILL, ON OCCASION, AUTOMATICALLY ACCELERATE EXCESSIVELY. THIS CAUSES THE DRIVER TO NEED TO STEP AGGRESSIVELY ON THE BRAKE IN ORDER TO CONTROL THE CAR. THIS CYCLE OF "RACE AND BRAKE" CONTINUES UNTIL OUR NEED TO REVERSE IS COMPLETE. ONCE WE ARE IN DRIVE THERE IS NO FURTHER PROBLEM. THIS HAS OCCURRED ABOUT SIX TIMES SINCE WE PURCHASED THE CAR IN LATE JULY. IT HAS MOST OFTEN OCCURRED WHEN IT IS THE INITIAL DRIVE OF THE DAY, BUT THE MOST RECENT TIME THE CAR HAD ALREADY BEEN DRIVEN 100 MILES AND HAD BEEN IDLING FOR SEVERAL MINUTES. WE CONTACTED THE DEALERSHIP FROM WHICH WE BOUGHT THE CAR. THEY HAVE NOT HEARD OF THE ISSUE. WE ALSO TOOK IT INTO OUR LOCAL DEALERSHIP. THEY WERE, OF COURSE, NOT ABLE TO REPLICATE THE PROBLEM. NO RESOLUTION OR CORRECTION HAS OCCURRED. *TR

AFTER THE RECALL SERVICE ON MY 2010 TOYOTA PRIUS, THE BRAKING SYMPTOM STILL OCCURRED ON TWO OCCASIONS ON MARCH 2, 2010 AND ON MARCH 4, 2010. IN BOTH CASES THERE WAS A DELAY IN BRAKING WHEN THE BRAKE WAS APPLIED WHILE ON A MODERATELY BUMPY ROAD SURFACE. ALTHOUGH DIFFICULT TO MEASURE THE DELAY MAY HAVE BEEN BRIEFER THAN PREVIOUSLY, BUT IT WAS STILL SUFFICIENT THAT IT WOULD HAVE BEEN A SAFETY HAZARD IF THERE WAS A VEHICLE OR OBSTRUCTION IN FRONT OF ME. *TR

MY DAUGHTER WAS DRIVING THE 2010 TOYOTA PRIUS INTO A SHOPPING CENTER'S PARKING LOT. SHE NOTICED SOME BLACK ICE ON THE GROUND AND STEP ON THE BRAKE. THE CAR DIDN'T STOP AND SLIP ON THE ICE AND THEN HIT THE CURB. THE REPAIR COSTS OVER $7300, AND IT'S THE TOYOTA DEALER DID THE REPAIR WORK. BACK IN LATE OCTOBER AND EARLY NOVEMBER TIME FRAME, WHEN I WAS DRIVING THE CAR OVER A SPEED BUMP WITH SPEED AROUND 15M/H, THE BRAKE DIDN'T WORK, THE CAR JUST SURGE FORWARD, EVENTUALLY SLOW DOWN AFTER 1 SECOND OR SO. *TR
