2010 TOYOTA PRIUS Vehicle Speed Control Problems

The contact owns a 2010 Toyota Prius. The contact stated while driving 45 MPH downhill on a mountain and depressing the accelerator pedal, the pedal travelled down to the floorboard, but the vehicle failed to accelerate as intended. The contact pulled over to the side of the road. The contact stated that upon turning off and restarting the vehicle several times, the vehicle responded as needed. The contact stated that the failure recurred after making a turn at 3-4 MPH downhill. The vehicle was not diagnosed or repaired. The dealer and the manufacturer were notified of the failure. The failure mileage was 194,000.

Mileage: 194,000

Heading westbound on I-70, taking Exit 29 off ramp from highway, I drove over uneven pavement. My traction control, ABS and brake lights illuminated, the brakes suddenly felt mushy. As I approached the stoplight at the end of the exit ramp, I questioned whether I would be able to stop. Scared me immensely. Luckily no cars were near me. I now do not have ABS, Traction Control, stability control OR regenerative braking.

My car accelerated significantly on its own while I was pulling into a parking stall in a private parking lot. It caused my vehicle to jump a curb and accelerate up a dirt divider and push over a bush that was planted in the dirt divider. Depressing my brakes did not Decelerate the car, so I pressed the Park button to eventually stop the vehicle. I’m not sure what speed it was traveling when it accelerated, but I could smell burning rubber at the end of the incident. I’m not sure when the smell first occurred.

see all over the internet that 2010 Prius have a recall for Inverter. I called the dealer they said no recall with my vin. I was told that a new inver is almost $5000 dollars. i NEED HELP i HAVE BOUGHT 3 TOYOTA ALREADY. Please help me with good will or warrenty the inverter like you have so many other people with 2010 Prius. If not I willand my family will never buy a Toyota again. Please call or email me [XXX] [XXX] The Prius died when driving and we almost got in a major accident because it stalled with no warning. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Total malfunction at highway speeds. Very unsafe, the car completely shut off. This may have resulted in a highway fatality due to collision as the vehicle was in the fast lane. NTSA please do your due diligence and investigate the faulty, defective HYBRID system as I believe the faulty inverter recall is much more larger than the original recall

The breaking lights, skid lights and another light associated with breaks came out and I lost the ABS abilities, the hv battery is not charging while breaking. These lights comes out randomly. Very risky especially while breaking.

The ABS, VSC/traction control, and brake system warning lights all came on at the same time in my 2010 Toyota Prius. I almost lost control of my car's braking ability. Afterwards, the hybrid system does not perform its regenerative braking/recharging any longer. And the cruise control mode doesn't work also. The DTC from the OBD2 port is C1391 - abnormal leak in the brake fluid accumulator. I found out that this issue is widespread among Gen 3 Priuses, but Toyota has not made this officially a recall campaign, but classifies it as a "customer support bulletin." But the issue is dangerous enough that it should be a recall item. I moved homes in fall of 2018, and Toyota says it mailed out a letter about this brake issue and resulting campaign, but I never received the letter. I was totally unaware that this was a safety issue, that Toyota acknowledged it, and that this safety issue with an ongoing "recall" campaign with an expiration date. Toyota denies that this is a recall issue, and will not provide this service. I would like for NHTSA to reopen and investigate this issue, and make Toyota issue a general recall campaign to resolve this dangerous safety problem with the car.

I was driving my 2010 Toyota Prius and my car started beeping when I was driving when I tried to slow down the car was not able to stop the breaking system ABS started displaying and my car started to beep and it won’t stop beeping. I did take my car to the dealer for a recalled inspection after my car broke down and I was no longer able to drive for my own safety. After I took the car to Downey Toyota for hybrid recall they didn’t tell me anything but on the document they gave me it did state that the ABS was a problem. Now my car is still not able to be used because of my own safety concerns since the vehicle won’t break when I put the brake pedal and a none stop beeping sound that won’t stop at all.

The digital speedometer display has stopped working. I can no longer see my speed or fuel gauge. I was quoted nearly $3,000 at the dealer to repair the vehicle.

The dash lights on my 2010 Prius went all dark, lost all information on my dash. No lights on dash, no fuel gauge, no speedometer, nothing. This is very dangerous to suddenly have happened and I don't see a recall from Toyota to address this problem.

Check hybrid system light ignites, slows down vehicle in middle of high speed highway. First incident November of 2020 then several incidents after. Repair shops don't assure problem according to error codes & they recommend possibilities they cannot assure will resolve the problem. Car was taken into local dealership after receiving recall notice for software and airbags prior to November 2020 when the issue began. Software update took a couple of hours. Restart/reboot temporarily allowed driving again. Most recently the system entirely shut down & the car will not start or run. Abandoned car on side of the road and got heat exhaustion from walking the rest of the way home and had vehicle towed. Error lights come on including "check hybrid system" says "shift to P position when starting" and will not allow start.

MY CAR IS ACCELERATING WHILE BRAKING. WHENEVER I TRY TO BRAKE ON THE ROAD WHILE CURBING OR STOPPING AT THE TRAFFIC SIGNALS, THE CAR SKIPS/SLIDE FORWARD. IT'S GETTING WORSE ON THE RAINY TIME THOUGH.

DEFECT WITHIN THE BRAKE BOOSTER PUMP ASSEMBLY. IF THIS DEFECT OCCURS, VARIOUS WARNING LAMPS ON THE INSTRUMENT PANEL MADE ILLUMINATE, I EXPERIENCE INCREASED STOPPING DISTANCE, REDUCED HYDRAULIC PRESSURE WITHIN YOUR BRAKE SYSTEM, THE DEACTIVATION OF BRAKE ASSIST, AND/OR THE DEACTIVATION OF VEHICLE STABILITY CONTROL. TOYOTA HAS PREVIOUSLY ISSUED AT LEAST TWO SAFETY RECALLS ' D0H AND K0L ' DESIGNED TO PREVENT SIMILAR DANGEROUS OCCURRENCES. HOWEVER, HUNDREDS OF THOUSANDS OF GENERATION III PRIUS VEHICLES (2010-2015 MODEL YEARS) WERE EXCLUDED FROM THOSE SAFETY RECALLS.

AS I WAS DRIVING ON A ROAD, ABOUT 25 MPH, WHILE MY FOOT WAS ON THE ACCELERATOR PEDAL THE CAR JUST DECREASED IT'S SPEED TO A STOP AS I CONTINUALLY PUSHED MY FOOT ON THE PEDAL.

CAR WORKED FLAWLESSLY AND WE MAINTAINED IT REGULARLY. TOOK IT IN TO ADDRESS RECALL OF JOV UPDATE PWR MGMT ECU AT DEALER. DEALER COMPLETED RECALL WORK. 2 DAYS LATER ENGINE LITE CHECK HYBRID SYSTEM AND THE ! ON AND TRIANGLE ON. THE CAR CONTINUED RUN BUT NOW WAS STUDDERING WHEN WAS NOT BEFORE THE RECALL WORK. TOOK IT BACK TO THE DEALER AND HE SAID WE NEED A NEW HYBRID BATTERY. WE BELIEVE THE SOFTWARE UPDATE THEY DID CREATED A THIS ISSUE. DEALER ACTING IGNORANT AND SAYING IT NEEDS NEW BATTERY BECAUSE OF NUMBER OF MILES ON CAR. ASKED FOR DIAGNOSTIC PRINT OUT FROM WHEN THEY DID RECALL WORK TO THEY NEW DIAGNOSIS AND THEY WOULD NOT PROVIDE. WE BELIEVE THE RECALL UPDATE CREATED A TECHNICAL PROBLEM WITH OUR HYBRID BATTERY. WE ALSO BELIEVE THAT DEALER NOT BEING HONEST REGARDING ISSUES WITH THIS RECALL UPDATE AND IS USING IT AS AN OPPORTUNITY TO REDUCE LIABILITY FOR TOYOTA ON FAILED RECALL WORK AND TO USE IT AS AN OPPORTUNITY TO BRING IN LARGE TICKET SALES REPAIR IE THEY QUOTED US A NEW HYBRID BATTERY FOR 5,500.

I HAVE BEEN EXPERIENCING THE SAFETY RISKS OUTLINED IN THE FOLLOWING MANUFACTURER RECALL NUMBER: J1V NHTSA RECALL NUMBER: 18V684 I HAVE BEEN DEALING WITH THIS ISSUE FOR THE PAST 2 - 3 YEARS AND UNKNOWINGLY MAY HAVE BEEN SPENDING HUNDREDS OF DOLLARS ON REPAIRS THAT MAY NOT HAVE NEEDED TO BE REPLACED. CURRENTLY, MY CAR IS NOT RUNNING AS I EXPERIENCED A STALL (11/09/2018) WHILE EXITING THE FREEWAY AT A HIGH SPEED WITH THE SCREEN READING "CHECK HYBRID SYSTEM" AND THE DASH LIT UP WITH THE YELLOW TRIANGLE AND EXCLAMATION POINT. I AM NOT ABLE TO ACCELERATE DURING THE STALL, BRAKES ARE WORKING. THIS HAS HAPPENED TO ME COUNTLESS TIMES, ALMOST ALWAYS ON THE FREEWAY OR EXITING AND WHILE TRAVELING AT A HIGH SPEED. SOMETIMES THE VEHICLE WOULD START BACK UP AFTER A FEW MINUTES OF BEING TURNED OFF. THIS PARTICULAR TIME (11/09/2018), I COASTED THE VEHICLE TO A SAFE SPOT AND THE VEHICLE ENGINE NEVER TURNED ON AGAIN. I TOWED THE VEHICLE TO MY RESIDENCE AND THEN TO MY MECHANIC. I AM ONLY ABLE TO PUT THE VEHICLE IN NEUTRAL. THE MOTOR WILL NOT COME ON AT ALL AND THE SCREEN READS "CHECK HYBRID SYSTEM". THE CAR HAD OVER 1/4 TANK OF GAS AT THE TIME. I CURRENTLY USE MY VEHICLE FOR MY LIVELIHOOD DOING INDEPENDENT DELIVERY SERVICES SUCH AS INSTACART, DOORDASH, POSTMATES ETC. SINCE THERE IS YET TO BE A REMEDY FOR THIS SITUATION I WANT TO KNOW WHAT MY OPTIONS ARE TO GET BACK THE MONEY I'VE SPENT OR COMPENSATION FOR THIS VEHICLE SINCE IT IS NOT USABLE AND UNABLE TO BE FIXED BY THE MANUFACTURER IN A TIMELY MANNER. I CAN PROVIDE DOCUMENTATION IN REGARDS TO REPAIRS MADE AS WELL AS VISITS TO TOYOTA IN WHICH THEY WERE UNAWARE OF THE ISSUE.

ON TWO OCCASIONS, JUNE 22, 2018 AND AUGUST 15, 2018 THIS VEHICLE SUDDENLY ACCELERATED WHILE USING CRUISE CONTROL AND TRAVELING AT SPEED ON GENERALLY FLAT, STRAIGHT, 4 LANE ROAD IN GOOD WEATHER. I HAVE ATTACHED DOCUMENTS WITH SUMMARIES OF EACH EVENT AND MAPS SHOWING ROUTE AND TERRAIN DURING THE EVENTS. HARD BRAKING SLOWED BUT DID NOT STOP THE VEHICLE EITHER TIME. BOTH TIMES, AFTER TRAVELING SOME DISTANCE WHILE BRAKING BUT CONTINUING TO ACCELERATE WITHOUT MY FOOT ON THE ACCELERATOR, THE VEHICLE MADE A THUNKING NOISE FELT THROUGH THE FLOOR OF THE CAR AND SUDDENLY STOPPED ACCELERATING. IN THE FIRST INCIDENT THIS WAS AFTER ABOUT 2 MILES, THE SECOND TIME AFTER ABOUT A MILE. AFTER EACH INCIDENT I PHONED THE LOCAL DEALERSHIP AND WAS TOLD THAT IF THEY COULD REPLICATE THE EVENT THEY MIGHT BE ABLE TO FIGURE IT OUT. I REPORTED THE EVENTS TO CORPORATE TOYOTA AND AN INVESTIGATION WAS OPENED. THE VEHICLE WAS TAKEN TO FRED ANDERSON TOYOTA OF ASHEVILLE WHERE THEY SPENT SEVERAL DAYS WITH THE CAR, INTERACTING WITH TOYOTA, WHO WAS ASKING THEM TO EXPLORE AND TEST VARIOUS THINGS RELATED TO THE DUAL PEDAL FAIL SAFE, THE COMPUTER, SNAPSHOTS OF EVENTS ON THE COMPUTER ETC. THEIR FINAL JUDGEMENT WAS THAT FLOOR MATS MAY HAVE INTERFERED, THOUGH IT WAS THE FIRST THING I CHECKED WHEN I REGAINED CONTROL OF THE CAR.

BRAKE ACTUATOR HAS FAILED. TRACTION CONTROL, ABS, BRAKE LIGHTS ILLUMINATED ON DASH. MORE EFFORT NEEDED TO ENGAGE BRAKES. THIS AFFECTS THE REGENERATIVE BRAKING AS IT NO LONGER CHARGES ON BRAKING AS IT WAS DESIGNED. CHECKED TOYOTA WEBSITE FOR RECALLS SINCE THIS IS SAFETY RELATED, AND THERE ARE NONE. WHICH IS QUITE DISTURBING. I'VE RESEARCHED PRIUS FORUMS AND THIS SEEMS TO BE AN ONGOING PROBLEM. TOYOTA ISSUED A RECALL FOR THE GENERATION 2 MODEL, HOWEVER THIS SEEMS TO BE A PROBLEM FOR GENERATION 3 MODELS AS WELL. THE PROBLEM DID OCCUR WHEN ON THE HIGHWAY TRAVELING AT 60 MPH.

Mileage: 60,600

I WAS DRIVING ON THE FREEWAY AT ABOUT 70 MPH WHEN THE "CHECK HYBRID SYSTEM" LIGHT CAME ON AND THE CAR LOST ALL POWER AND ABILITY TO ACCELERATE. IT COMPLETELY BEGAN TO DESCEND IN SPEED AND WITHIN 2 MINUTES CAME TO A COMPLETE SHUT DOWN. I COULD HAVE EASILY BEEN REAR ENDED HAD I NOT MOVED TO THE SIDE OF THE FREEWAY AS QUICKLY AS I DID.

Mileage: 170,000

I CHANGE THE BRAKE BOOSTER TWICE AND HACE THE SAME PROBLEM. MY BRAKE PEDAL LOSS OF BRAKING ABILITY OR SLIPPING BRAKES AND THE WARNING BRAKE, ABS AND TRACTION LIGHT PERMANENTLY ON, AND NO CRUISE CONTROL WORKS AT ALL

TL* THE CONTACT OWNED A 2010 TOYOTA PRIUS. WHILE PARKING THE VEHICLE, IT UNEXPECTEDLY ACCELERATED AND STRUCK ANOTHER VEHICLE BEFORE CRASHING INTO AN APARTMENT UNIT. A POLICE REPORT WAS NOT FILED AND THERE WERE NO INJURIES. THE AIR BAGS DID NOT DEPLOY. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC, BUT THE CAUSE OF THE FAILURE COULD NOT BE DETERMINED. THE MANUFACTURER WAS CALLED AND PROVIDED THE CONTACT WITH AN INVESTIGATOR WHO REMOVED A BOX FROM THE VEHICLE, WHICH WOULD DETERMINE IF THE FAILURE WAS DUE TO DRIVER ERROR OR A SAFETY DEFECT. THE MANUFACTURER DETERMINED THAT IT WAS DRIVER ERROR. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 53,000.

IN THE PAST YEAR I HAVE HAD 2 OCCURRENCES OF UNINTENDED ACCELERATION. THE FIRST IN FEBRUARY OF 2016. I WAS EXITING A PARKING RAMP UP HILL AND STEPPING ON THE ACCELERATOR. I WAS DRIVING STRAIGHT THEN TURNING TO THE LEFT (90 DEGREE TURN). WHEN I TOOK MY FOOT OFF THE ACCELERATOR, THE CAR CONTINUED TO ACCELERATE AND I WAS UNABLE TO GET IT SLOWED/STOPPED FOR ABOUT A BLOCK EVEN THOUGH I WAS APPLYING HEAVY BRAKE PRESSURE. THE CAR WAS REVVING AGAINST THE BRAKE PRESSURE. NO DAMAGE OR INJURIES OCCURRED. I TOOK THE CAR TO THE DEALERSHIP WHERE I PURCHASED IT (PURCHASE DATE 8/3/13). THEY CHECKED THE CAR OVER AND FOUND NO APPARENT CAUSE FOR THE ACCELERATION. I TOOK THE CAR HOME, AND IT DROVE NORMALLY UNTIL 11/26/16. ON THAT DATE I WAS DRIVING VERY SLOWLY IN A FLAT PARKING LOT, AND THE CAR BEGAN ACCELERATING WITHOUT MY PUSHING THE GAS PEDAL. I WAS DRIVING STRAIGHT AND THEN TURNING TO THE RIGHT (90 DEGREE. I GOT THE CAR STOPPED IN A FEW FEET BY PRESSING EXTREMELY HARD ON THE BRAKE. MY CAR DID NOT HIT ANYTHING. TECHNICIANS FROM THE DEALERSHIP HAVE NOT BEEN ABLE TO FIND A CAUSE AND I HAVE NOT BEEN ABLE TO GET PAST TOYOTA'S CUSTOMER SERVICE DEPARTMENT TO ESCALATE THE ISSUE FOR MORE DETAILED DIAGNOSTICS. I HAVE ATTACHED THE TIMELINE OF TRYING TO GET THE CAR DIAGNOSED AND THE ISSUE ESCALATED AS WELL AS WHY I DON'T THINK USER ERROR IS A FACTOR. *TR

I WAS IN A PARKING STRUCTURE GOING APPROXIMATELY 15 MPH WHEN I REMOVED MY FOOT FROM THE ACCELERATOR TO PRESS THE BRAKE. BEFORE I COULD GET MY FOOT TO THE BRAKE, THE CAR QUICKLY ACCELERATED. IT TOOK AT LEAST TWO ATTEMPTS AT PUSHING THE BRAKE PEDDLE BEFORE THE CAR CAME TO A STOP. AND, TO BE HONEST, THE GUARDRAIL THE CAR HIT HELPED ACTUALLY STOP THE VEHICLE. IT WAS TOTALLY UNEXPECTED AND EXTREMELY SCARY. IN HINDSIGHT, I SHOULD HAVE SUSPECTED THAT THERE MAY BE A PROBLEM WHEN I NOTICED THAT SOMETIMES WHEN APPLYING THE BRAKES TO COME TO A STOP THERE WOULD BE A FEELING OF THE BRAKES SLIPPING AND THE CAR LURCHING FORWARD A BIT. THE DEALERSHIP HAD THE CAR TOWED IN TO GET CHECKED OUT, AND I HAVE BEEN TOLD THAT THEY WILL NOTIFY TOYOTA. IN THE MEANTIME I AM CONCERNED ABOUT THE SAFETY OF THIS CAR!

ON 05/25/2016 AT ABOUT 9AM, WHILE IN MOTION AT A RATE OF SPEED APPROX 25 MPH ON A STREET DURING CONSTRUCTION (DON'T KNOW IF THE BUMPY ROAD HAD ANYTHING TO DO WITH IT), THE CHANGE OIL SOON LIGHT APPEARED AND SECONDS LATER ALL THE LIGHTS ON THE DASH CAME ON WITH THE MESSAGE TO CHECK THE "CHECK HYBRID SYSTEM" . I TRIED TO STOP THE VEHICLE AND IT KEPT ACCELERATING. I PRESSED ON THE BREAKS REALLY HARD AND THE TRACTION CONTROL LIGHT KEPT FLASHING ON AND OFF LIKE CRAZY BUT IT BARELY HAD ANY IMPACT. ALTHOUGH THE VEHICLE SLOWED, IT DID NOT COME TO A FULL STOP. I ENDED UP HITTING THE VEHICLE IN FRONT OF ME. THANK GOD IT WAS A TRUCK AND AS ABLE TO STOP THE CAR FROM MOVING FURTHER OR I COULD OF ENDED UP IN THE MIDDLE OF AN INTERSECTION. AFTER THE COLLISION, THE CAR WOULD NOT STOP ALTHOUGH THE PARK BUTTON WAS PRESSED AND LIGHT WAS ON. I EVEN TRIED TURNING OFF THE VEHICLE AND THE VEHICLE STAYED ON AND IN DRIVE. I ENDED UP IN THE HOSPITAL AND DON'T KNOW HOW IT EVENTUALLY GOT TURNED OFF BUT THAT WAS VERY FRIGHTENING. I HAD MY CHILDREN IN THE CAR. ON IMPACT, THE SEAT BELTS DID NOT EVEN TIGHTEN.

I AM WRITING DUE TO HAVING HAD MY 2010 TOYOTA PRIUS SELF ACCELERATE WHILE DRIVING ON FOUR OCCASIONS. THIS BEGAN OCCURRING AFTER I TOOK MY VEHICLE TO TOYOTA OF CLERMONT, FLORIDA FOR A ROUTINE SERVICE ON 3/31/2014. WHILE THE VEHICLE WAS THERE, THE DEALERSHIP ALSO PERFORMED A RECALL ON THE VEHICLE. THIS RECALL IS REFERENCED AS: TECH(S) : 20799 RECALL EOE MOTOR GENERATOR AND POWER MANAGEMENT UPDATE PERFORM SOFTWARE UPDATE FOR MG ECU AND POWER MANAGEMENT ECU AGG09A 0.7 AS OF 8/5/2014 MY VEHICLE HAS HAD UNINTENDED ACCELERATION ON 4 OCCASIONS. IN 3 OF THE 4 I KNOW IT HAS OCCURRED AS I RELEASED THE BRAKE. THIS RELEASE IS CONFIRMED BY THE FACT THAT IT IS NECESSARY TO REAPPLY THE BRAKE TO STOP THE ACCELERATION. THE 4TH OCCURRENCE MAY ALSO HAVE OCCURRED AFTER A BRAKE RELEASE. I HAVE ATTEMPTED TO RESOLVE THIS PROBLEM VIA BOTH MY LOCAL TOYOTA DEALER AND TOYOTA CUSTOMER EXPERIENCE CENTER AT 1 800 331-4331. I AM BEING TOLD THE PROBLEM IS OPERATOR ERROR. I HAVE DONE THE RESEARCH TO SEE IF THIS IS EVEN POSSIBLE. FOR ME TO APPLY THE BRAKE AND FUEL SIMULTANEOUSLY WOULD BE BOTH EXTREMELY DIFFICULT AND VERY OBVIOUS. ADDITIONALLY IF THIS DIAGNOSIS WERE CORRECT THE VEHICLE WOULD STOP ACCELERATING WHEN THE BRAKE WAS RELEASED. IN FACT THE VEHICLE ACCELERATES WHEN THE BRAKE IS RELEASED NOT WHILE THE BRAKE IS DEPRESSED. *TR

IF THE VEHICLE HITS A POT HOLE WHILE SLOWING DOWN, THERE'S A SUDDEN LOSS OF BRAKING POWER AND THE VEHICLE MOVES A FEW FEET FORWARD. THE VSC LIGHT COMES ON AT THE SAME TIME. I'D NOTICED THIS A FEW TIMES IN THE PAST BUT WITH THE ROADS DETERIORATING AFTER A BAD WINTER, THE POT HOLES ARE BIGGER AND THIS IS VERY PROMINENT AND SCARY. GOING TO TAKE TO THE DEALER FOR INSPECTION. I FEEL IT'S DEFINITELY AN ISSUE WITH THE BRAKING SYSTEM. *TR

WHEN PARKING, MY 2010 PRIUS ACCELERATED FORWARD CAUSING IT TO GO OVER A CURB FORM DAMAGING THE FRONT BUMPER. UNEXPECTED ACCELERATION HAS CAUSED FOUR ACCIDENTS DAMAGING MY CAR.

I STARTED NOTICING A HIGH PITCH NOISE SPORADICALLY ON MY CAR AFTER IT WAS A FEW MONTHS OLD. IF I STOPPED AND RESTARTED THE CAR, THE NOISE WOULD GO AWAY. WHEN I BROUGHT IT TO TOYOTA THEY COULD NOT REPRODUCE THE PROBLEM. IT WOULD HAPPEN ABOUT 1-3 TIMES PER MONTH AND SOME MONTHS NOT AT ALL. ON THIS PARTICULAR TRIP ABOUT A MONTH AGO, I DID NOT NOTICE THE NOISE ON START UP (I HAD A COLD THAT AFFECTED MY HEARING), BUT DID HEAR IT AFTER GETTING ON THE HIGHWAY. THERE WAS NO WHERE TO REASONABLY PULL OVER AND RESTART THE CAR SAFELY, SO I KEPT DRIVING. AFTER ABOUT 15-30 MINUTES THE SPEEDOMETER CLUSTER/DASH THAT DISPLAYS THE SPEED, FUEL AND DRIVE POSITION WENT BLANK AND THE NOISE WENT AWAY. SEARCHING ONLINE THERE WERE AT LEAST A HANDFUL OF OTHERS WHO EITHER HAD THEIR SPEEDOMETER REPLACED UNDER WARRANTY OR OTHERWISE WITH THE SAME ISSUE. I ALSO FOUND A RECALL ON THE 2009, A YEAR EARLIER, PRIUS FOR THE SAME ISSUE AND YES THE SAME COMPANY MAKES THE PART. I BROUGHT MY CAR TO THE DEALER ASAP AND THE DEALER WANTED TO CHARGE ME $120 TO DIAGNOSE. WHEN I QUESTIONED THEM, THEY SAID THEY NEED TO TAKE THE DASH APART, WHICH IS A LIE AS THIS WOULD BE MORE EXPENSIVE AS PER OUR CONVERSATION. I ASKED FOR A QUICK COMPUTER DIAGNOSIS AND THEY REFUSED. I THEN CALLED TOYOTA WHO SAID MY CAR IS LONG OUT OF WARRANTY FOR THIS PART AND THAT BECAUSE I DIDN'T PAY FOR A DIAGNOSIS THEY WOULD NOT TAKE IT FURTHER. WHEN I PRESSED ON WITH THEM THEY HID BEHIND CONFIDENTIALITY WHEN I ASKED ABOUT OTHERS WHO HAD THIS ISSUE AND THEN THEY SAID EVEN IF I PAID FOR A DIAGNOSIS AND THIS WAS FOUND DEFECTIVE THERE ARE NO PROMISES.

I CALLED FOR TOWING SERVICE AND HAD THE CAR TOWED TO MY TOYOTA DEALER, WHERE THE SERVICE PEOPLE SAID IT WAS AN "INTERNAL FAILURE" AND REPLACED THE INVERTER ASSEMBLY. WHAT HAS TERRIFIED ME IS THAT I COULD HAVE BEEN ON THE FREEWAY DRIVING AT LEAST 60 MPH, WHERE THE CONSEQUENCES WOULD BE DEVASTATING TO ME AND OTHERS.

WHILE RETURNING FROM WORK AT 5:30 PM, 02/18/14 ON HIGHWAY 90 WEST TO ALBANY, NY, WITH CRUISE CONTROL SET TO 50 MPH, THE ACCELERATOR PEDAL GOT STUCK ON MY 2010 TOYOTA PRIUS. THE PEDAL DID NOT RETURN BACK TO ITS ORIGINAL POSITION EVEN WHEN I TURNED OFF CRUISE CONTROL. I SPONTANEOUSLY TAPPED THE ACCELERATOR PEDAL IN THE HOPE OF RELEASING BUT DID NOT YIELD ANY RESULTS AND THE VEHICLE MAINTAINED ITS SPEED. APPLYING BRAKES MADE NO EFFECT AND DID NOT CURTAIL THE CAR. IT CONTINUED TO MOVE WITH ALMOST THE SAME SPEED EVEN WHEN BRAKE PEDAL DEPRESSED. I HAD NO CONTROL ON MY CAR IN ONE OF BUSIEST FREEWAYS. I CONTINUOUSLY APPLIED THE BRAKES AND TRIED TO MERGE TO THE RIGHT MOST LANE WITH HAZARD BLINKERS ON. IT TOOK MORE THAN 5 MILES PANIC RIDE TRYING TO AVOID TRUCKS AND OTHER CARS TO MERGE TO THE RIGHT LANE. EVEN WITH THE BRAKE FULLY DEPRESSED, THE 2010 PRIUS DID NOT SLOW DOWN AND I MANAGED TO REACH THE SHOULDER LANE WHICH HAD GRAVEL & SNOW. THEN I PRESSED PARK BUTTON AND SWITCHED OFF THE ENGINE BY PRESSING THE POWER BUTTON. I COULD FEEL THE WHEELS LOCK UP BUT THE PRIUS CONTINUED TO MOVE WITH STRONG RUBBER BURNING SMELL. FINALLY, I ENGAGED THE PARKING BREAKS TO STOP IT FROM MOVING INTO THE FREEWAY. AFTER COMPLETE STOP, WITH DIFFICULTY I MANUALLY PULLED UP THE ACCELERATOR PEDAL. THIS ENTIRE ORDEAL WAS SHOCKING AND AN UNBELIEVABLE NARROW ESCAPE FROM A MAJOR CATASTROPHIC EVENT. I THANKED GOD & CALLED 911 AND THE HIGHWAY PATROL POLICE CAME TO THE SPOT AND PROMPTLY HELPED TO MOVE THE VEHICLE AND MYSELF FROM THE FREEWAY TRAFFIC. THE 2010 TOYOTA PRIUS WAS MOVED TO TOYOTA DEALER SERVICE CENTER WHERE I PURCHASED THE CAR & PERFORMED EVERY SCHEDULED MAINTENANCE SERVICE PUNCTUALLY. INCIDENTALLY THE LAST SERVICE AND CERTIFICATION WAS IN 12/2013. IT IS OBVIOUS THAT EVEN REGULAR DEALER MAINTENANCE SERVICE AND CERTIFICATION DID NOT HELP THIS VEHICLE. REPORT FILED WITH TOYOTA MOTOR CUSTOMER SERVICE. *TR

WHILE CAREFULLY PARKING MY PRIUS 2010 AT A HOSPITAL IT ACCELERATED SUDDENLY AND CRASHED OVER THE CEMENT CURB. I SAY CAREFULLY BECAUSE MY PRIUS HAD DONE THIS BEFORE BUT NOT ENOUGH DAMAGE WAS DONE TO FILE WITH INSURANCE. THERE FOLLOWED ANOTHER ACCIDENT AND ANOTHER ACCIDENT. THEN THIS EVENING WHILE DRIVING INTO MY CARPORT MY PRIUS ACCELERATED AGAIN. IT THREW MY DOG THAT WAS IN THE FRONT SEAT TO THE FLOOR BUT I WAS ABLE TO AVOID CAR DAMAGE AS I WAS GOING TO STOP. I WAS BARELY MOVING, THAT IS I STILL HAD MY FOOT ON THE ACCELERATOR,MAYBE I COULD SAY COASTING, WHEN THIS ACCELERATION SUDDENLY OCCURRED. THIS WAS THE SAME TYPE ACCELERATION THAT CAUSED ALL THE PRIOR ACCIDENTS. I HAVE REPORTED THIS TO TOYOTA... AND NOW YOU. HOPEFULLY YOU WILL HELP ME. MY PRIUS IS IN THE CARPORT. IT HAS NOT BEEN MOVED. HOWEVER, IT IS MY ONLY TRANSPORTATION. MY PRIUS' LATEST HAPPENING, BEFORE THE ONE JUST STATED, THE HYBRID SYSTEM QUIT WORKING DURING RUSH HOUR TRAFFIC ON THE INTERSTATE NEAR A BUSY INTERSECTION. THIS WAS REPAIRED BEFORE TOYOTA SENT SOME ONE TO INVESTIGATE THE PRIOR ACCIDENTS. IF MORE INFORMATION IS NEEDED JUST LET ME KNOW. THIS PRIUS ALSO HAD A BATTERY REPLACED SHORTLY AFTER IT WAS PURCHASED AS A NEW VEHICLE. THIS PRIUS HAS WHEEL RIM SCRATCHES. *TR

I HAVE A 2010 TOYOTA PRIUS THAT REALLY HAS ME CONCERNED. TWICE RECENTLY WHEN APPLYING THE BRAKES, IT HAS LUNGED FORWARD AND I WAS FORCED TO PUNCH THE BRAKES VERY HARD WITH BOTH FEET TO MAKE IT STOP. IT REALLY SCARED ME. LUCKILY THERE WAS NOBODY IN FRONT OF ME OR I WOULD HAVE HAD AN ACCIDENT. I TOOK IT TO THE DEALER (WALKER TOYOTA IN MIAMISBURG, OH) TO HAVE IT CHECKED OUT. THE SERVICE DEPARTMENT LOOKED BACK AT THE COMPUTER ON THE CAR AND SAW TWO INSTANCES WHERE THE BRAKE AND ACCELERATOR WERE PRESSED AT THE SAME TIME. SO NOW THEY ARE TRYING TO TELL ME IT IS USER ERROR. THEY SAID I MUST HAVE INADVERTADLY HIT THE ACCELERATOR PEDAL WHILE I WAS BRAKING. NO I DID NOT!!! I HAVE OWNED THIS CAR FOR OVER THREE YEARS AND THIS HAS NEVER HAPPENED BEFORE. NOW IT HAS HAPPENED TWICE IN THE LAST TWO MONTHS. I DON'T THINK SO... I CALLED TOYOTA CORPORATE AND THEY ADVISED ME TO GET A SECOND OPINION. SO NOW I AM TAKING IT TO VOSS TOYOTA IN BEAVERCREEK. I ALSO NOTICED RECENTLY THAT MY GAS MILEAGE HAS DROPPED SIGNIFICANTLY IN THE LAST SIX MONTHS. IT'S MUCH WORSE THAN IT'S EVER BEEN SINCE I HAVE OWNED IT. I'M NOT SURE IT IT IS RELATED OR NOT??? *TR

THIS CAN OBVIOUSLY BECOME A DEADLY SITUATION IF ONE IS TRYING TO STOP THE VEHICLE AND WITH THIS PROBLEM RUN INTO THE CAR/VEHICLE AHEAD. MOST RECENTLY THIS OCCURRED ON THE SURFACE STREETS IN LOW SPEED, IN TRAFFIC. IT FEELS LIKE THE CAR LURCHES AHEAD WHILE APPLYING THE BRAKE.

MY PRIUS IV, PURCHASED NEW IN 2010, INTERMITTENTLY HAD A LUNGING FORWARD PROBLEM WHEN GOING OVER SPEED BUMPS, POT HOLES ETC. I WOULD HAVE TO STOP IT BY BRAKING QUICKLY, SO I DIDN'T COLLIDE WITH A CAR AHEAD. I INFORMED TOYOTA OF THIS PROBLEM WITHIN THE FIRST YEAR. THEY TESTED IT AND SAID THEY COULD FIND NOTHING. I MENTIONED THIS TO THEM ON VARIOUS OCCASIONS WHEN I TOOK THE CAR FOR ITS PERIODIC MAINTENANCE OF 5000 MILE INTERVALS. ON DECEMBER 26, 2012 I WAS STOPPED WAITING TO GO LEFT WHEN I WAS REAR-ENDED. I WENT TO PULL OVER TO THE SIDE OF THE ROAD TO ASSESS THE DAMAGE. WHEN I ACCELERATED TO GET TO THE SIDE OF THE ROAD,THE CAR TOOK OFF CRAZILY, AT A HIGH RATE OF SPEED FOR ABOUT 6-7 SECONDS, ZIGZAGGING UNCONTROLLABLY ON THE 2 LANE ROAD. IF THERE WERE CARS COMING TOWARD ME, I WOULD HAVE BEEN IN A HEAD ON CRASH. I IMMEDIATELY CALLED TOYOTA SERVICE OF SCRANTON,PA AND ASKED THEM TO SEE AND ASSESS THE CAR'S PROBLEM. THEY MADE AN APPOINTMENT AND CONCLUDED.SAID THERE IS NO PROBLEM INTERNALLY, AND SUGGESTED REMOVING THE AFTER MARKET FLOORMAT. I THEN PROCEEDED TO SHOW THEM THE SAME PROBLEMS MANY CUSTOMERS ARE HAVING WITH THE PRIUS , INCLUDING AN ARTICLE BY STEVE WOZNIAK, THE CO-FOUNDER OF APPLE COMPANY, WHO HAD ACCELERATION PROBLEMS WITH HIS 2010 PRIUS. I CALLED THE MAIN TOYOTA HEADQUARTERS LATER, EXPLAINING THE PROBLEM AND THEY TOO SAID THERE IS NO MALFUNCTION , ONLY MENTIONING THE FLOOR MATS AGAIN.. THIS IS NOT THE CASE AS THE CAR HAS HAD ACCELERATION PROBLEMS FROM THE BEGINNING AND TO FURTHER CLARIFY, I WAS ABLE TO FINALLY STOP THE CAR... THE MAT WAS NO WHERE NEAR THE ACCELERATOR. I AM AFRAID TO DRIVE THIS FOR OTHERS' SAFETY, MY PASSENGERS AND MY OWN SAFETY. I TAKE CARE OF MY CARS FAITHFULLY. YOU CAN VIEW MY RECORDS. I AM ALSO FEARFUL IF I TRADE THIS CAR, SOMEONE ELSE MIGHT GET INJURED OR KILLED. CAN YOU PLEASE CHECK AND ADVISE. *TR

THE UNINTENDED ACCELERATION ACCIDENT HAPPENED ON 7/18/2012, ~6:20 PM AT COMPANY'S PARKING LOT. I BACKED MY 2010 PRIUS SLOWLY. THEN I SAW A CAR COMING ON MY WAY. BUT BEFORE I TOOK ANY ACTION, THIS PRIUS SUDDENLY STARTED ACCELERATING, IT WENT WILDLY, AND TURNED MORE THAN 360 DEGREE BACKWARD IN THE PARKING LOT IN JUST A FEW SECONDS. SINCE THE CAR PARKED BETWEEN A BUILDING AND A SLOP, FROM THE FRONT MIRROR, FIRST, I SAW THE BUILDING WALL AND GLASSES, THEN I SAW THE SLOPE, THEN I SAW A CAR PARKED CLOSE TO MY CAR: NO! DON'T HIT THAT CAR! THAT IS THE LAST THING I REMEMBER. BECAUSE OF THE FAST TURNING OF THE CAR AND BECAUSE I WAS SO TERRIBLY SCARED, I LOST CONSCIOUS AFTER THAT UNTIL THE PRIUS HIT THE TRUCK AND BOUNCED BACK AND STOPPED BY ITSELF. AFTER A FEW SECONDS, I WOKE UP AND REALIZED: I AM STILL ALIVE. I GOT OFF THE CAR AND SAW PRIUS PASSED THE TWO CURBS AND HIT THE TRUCK. THE TWO TIRES ON THE DRIVER SIDE GOT FLAT BECAUSE THEY PASSED THE CURB VERY FAST. I WAS SO SCARED THAT I COULDN'T RECALL OF ANYTHING FOR A FEW DAYS UNTIL WEEKEND. WHY DID THE CAR LOSE CONTROL? ONE MAY ARGUE THAT I STEPPED ON THE ACCELERATOR. THIS COULD HAPPEN TO NEW DRIVERS, BUT NOT TO ME BECAUSE I HAVE BEEN DRIVING FOR SO MANY YEARS AND ALWAYS A GOOD DRIVER. MANY TIMES I SAW A CAR ON MY WAY WHEN I WAS BACKING, I ALWAYS STOPPED RIGHT AWAY. AND I WAS HEALTHY IN A NORMAL DAY IN NORMAL MODE, ALERT AS USUAL. WHY WOULD I STEP ON ACCELERATOR WHEN BACKING? EVEN IF I MIS-STEPPED ON THE ACCELERATOR, I CAN ALWAYS SWITCH TO BRAKE RIGHT AWAY. BUT I COULD?T DO ANYTHING ABOUT THE CAR ON THE DAY. IT WAS OUT OF CONTROL COMPLETELY. AFTER I LOST CONSCIOUS, MY HANDS WERE OFF THE STEERING WHEEL AND MY FOOT DIDN'T STEP ON ANYTHING, THE CAR DIDN'T SLOW DOWN BUT STILL MOVED FAST AND PASSED TWO CURBS EASILY. SUCH A MANIPULATION CAN ONLY BE DONE WHEN THE CAR IS IN ACCELERATION, AND BY ITSELF. PLEASE INVESTIGATE IT ASAP! *TR

DESCRIPTION: WHEN TRAVELING AT RELATIVELY SLOW SPEEDS AND AN UNEXPECTED BUMP COMES UP AND THE BRAKES ARE ENGAGED EARLY, ONCE GOING OVER THE BUMP THE CAR LOSSES BRAKE POWER FOR A FEW SECONDS AND JOLTS FORWARD. IT IS VERY DISCONCERTING B/C IN THOSE SPLIT SECONDS IF ONE IS NOT PREPARED THE CAR HURLS FORWARD AND COULD IF ALL ODDS ARE AGAINST ME, THE CAR COULD KILL SOMEONE IF THEY ARE WALKING IN FRONT OF THE CAR. I REPORTED IT TO MY DEALER, MY DEALER'S INSPECTOR WENT OUT ON TEST DRIVE WITH ME, WE WERE ABLE TO RECREATE THE INCIDENT WHEN HE WAS DRIVING AS THERE ARE A FEW SPOTS IN MY NEIGHBORHOOD THAT IT HAPPENS EVERY TIME. HE PUT THE COMPUTER ON THE CAR BUT IT DID NOT READ THERE WAS A PROBLEM. HE CALLED THE NATIONAL TECHNICAL OFFICE, WHO EVENTUALLY CAME OUT, I LEFT THE CAR AT THE DEALERSHIP. THEY RECREATED THE PROBLEM AND ACCORDING TO THE LOCAL TECHNICIAN THEY PUT A CAMERA IN THE WHEEL TO FILM THE SITUATION. I WAS LATER TOLD BY MY LOCAL TECHNICIAN THAT IT WAS DETERMINED THAT THERE WAS NOT A PROBLEM WITH THE CAR AND THAT THE SITUATION IS NORMAL WHERE THE TIRE CATCHES AN UNEVEN SURFACE AND GOES INTO OVERDRIVE. I HAVE HAD DREAMS THAT I WOULD KILL SOMEONE IN THIS CAR. NOONE IS ALLOWED TO USE THIS CAR FOR THE SAME REASON. I FEAR FOR MY LIFE AND THE LIFE OF ANYONE WALKING IN FRONT OF ME ON A STREET I DO NOT KNOW. IT HAPPENS ALMOST EVERY 2 WEEKS. IT IS SCARY! PLEASE HELP! THIS IS THE FIRST NEW CAR I BOUGHT IN 25 YEARS AND I AM UNABLE TO GET RID OF IT B/C I HAD TO PAY SO MUCH FOR IT. WHEN I INQUIRED WHAT MY OPTIONS WERE, TOYOTA SAID NONE, THAT THERE IS NO PROBLEM WITH THE CAR. *TR

I TRAVEL QUITE A BIT THESE DAYS AND ON MY WAY HOME FROM COACHELLA MUSIC FESTIVAL, MY BRAKES GAVE OUT. I MEAN TO SAY, PUSHING THE PEDAL ALL THE WAY DOWN, NO RESISTANCE, NO SLOWING, A COMPLETELY LIMP PEDAL....UNTIL I REPEATEDLY STOMPED ON IT AND THE CAR LOCKED AND SKIDDED TO A STOP, FEET AWAY FROM THE CAR IN FRONT OF ME. THE BRAKES RETURNED INTERMITTENTLY, SO I TOOK THE RIGHT HAND LANE AT 40MPH AND TESTED THE BRAKES REGULARLY UNTIL I GOT TO MY DEALERSHIP. SCARIEST THING IVE EVER EXPERIENCED. IVE HAD THE CAR SINCE AUGUST 09' AND CURRENTLY HAVE 43K MILES ON IT. I KNOW THATS A LOT, AND ITS UNFORTUNATELY OUTSIDE OF MY WARRANTY NOW, BUT I WANTED TO LOG IT HERE, AS SOON AS I COULD. IT STARTED ONE DAY BEFORE THE FREEWAY INCIDENT, WHENEVER I WOULD DEPRESS THE PEDAL, A LOUD HIGH PITCHED SQUEAK WOULD COME OUT. I DIDNT THINK MUCH OF IT OUTSIDE OF "BETTER GET THAT LOOKED AT" BUT DIDNT NOTICE ANY BRAKE FAILURE. THE NEXT MORNING, I TURNED ON THE CAR AND EVERY DASHBOARD LIGHT CAME ON AND A FAST CONSISTANT BEEPING WENT ON FOR ABOUT 5 MINUTES, DURING WHICH TIME THE BRAKE PEDAL HAD ZERO RESISTANCE. I SAT THERE WITH A SERIOUS WTF LOOK ON MY FACE, WHEN OUT OF NOWHERE, THE DASH LIGHTS WENT AWAY, AS DID THE BEEPING, AND THE CAR DROVE AS NORMAL WITH FULL REGULAR BRAKE PRESSURE (BESIDES THE SQUEAK). I RECEIVED A CALL BACK FROM THE DEALERSHIP.

UPDATED 11/19/10. *LJ THE CONSUMER STATED SHE HAD NO CONTROL OF THE VEHICLE, IT JUST SUDDENLY ACCELERATED ON ITS OWN. THE VEHICLE JUMPED OVER A CURB BORDERING THE PARKING LOT, THEN OVER A DRAINAGE DEPRESS/GRASS MEDIAN THROUGH A SIZEABLE SHRUB EDGE. THE VEHICLE THEN SLAMMED INTO A CONCRETE SIDEWALK AND DOWN TO THE STREET CURB, FINALLY STOPPING WITH THE MOTOR OFF AND HAVING BLOWN TWO TIRES. UPDATED 12/01/10*JB

TOYOTA PRIUS 2010, MY PROBLEM IS SOMETIMES THE GAS PEDAL DOES NOT RELEASE WHEN TRYING TO STOP, I HAVE FOUND THAT BY RELEASING THE BRAKE PEDAL THE THROTTLE RELEASES, THIS ALWAYS HAPPENS UNDER THE SPEED OF 40 MPH. THIS PROBLEM IS ALWAYS RANDOM, AND YOU NEVER KNOW WHEN IT WILL HAPPEN, IT HAS HAPPENED ABOUT 30 TIMES SO FAR, THIS STARTED ABOUT 6 MONTHS AGO. IS THIS PROBLEM PART OF THE RECALL. *TR

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

CASE OF SUDDEN UNINTENDED ACCELERATION IN A NEW 2010 TOYOTA PRIUS: I WAS PARKING MY CAR IN A PULL-IN PARKING SPOT IN AN OFFICE BUILDING PARKING LOT. WHILE STRAIGHTENING THE CAR OUT IN THE SPOT, IT SUDDENLY ACCELERATED OUT OF CONTROL AND JUMPED A CURB IN FRONT OF LANDSCAPED SHRUBBERY. A LARGE WOODY BUSH, AND SOFT DIRT STOPPED THE VEHICLE. NO ONE ELSE WAS INVOLVED IN THE ACCIDENT. THE CAR HAS ONLY 2200 MILES ON IT. THE CAR IS CURRENTLY BEING HELD BY THE DEALER, TOYOTA SCION OF EATONTOWN, NJ. *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

TODAY AT YET ANOTHER CHECK FOR MY 2010 PRIUS TO TRY TO DISCOVER THE CAUSE FOR THE CONTINUAL SURGING, I WAS INFORMED THAT 160 TIMES IN THE LAST 1 1/2 MONTHS I HAVE DRIVEN WITH BOTH THE GAS AND BRAKE PEDALS DEPRESSED SIMULTANEOUSLY. THIS IS A RIDICULOUS ASSERTION AND COMPLETELY FALSE. OBVIOUSLY THERE IS AN ISSUE WITH THE COMPUTER SOFTWARE IN MY PRIUS BRAKES.

I HAVE A 2010 TOYOTA PRIUS PURCHASED IN JULY 2009. DURING OWNERSHIP I EXPERIENCED WHEN THERE WAS A CREASE, HOLE OR BUMP IN THE ROAD WHEN BRAKING - IT ACCELERATING AND LUNGES. I AVOIDED SITUATIONS LIKE THAT AND WHEN THE RECALL CAME, I TOOK IT TO BUTLER TOYOTA (ALSO HAD THE FLOOR MAT HOOKS INSTALLED PRIOR), ON APRIL 5, 2010. THEY SUPPOSEDLY FIXED IT. ABOUT A WEEK LATER, I CAME UPON A MANHOLE COVER IN A ROAD WHILE BRAKING AND MAKING A TURN SO GOING SLOW, AND THE SAME THING HAPPENED. THE NEXT DAY I PURPOSELY WENT THROUGH IT TO "TEST" AND IT DID THE SAME THING BUT LUNGE INTO THE OTHER LANE. I WAS SCARED AND CALLED BUTLER TOYOTA. THEY TOLD ME TO CALL NATIONAL TOYOTA TO REPORT. THEY CONTACT BUTLER AND I WENT BACK IN MAY 21, THEY DID NOT REPAIR IT AND "SHRUGGED" THEIR SHOULDERS SAYING IT'S THE ABS. THEY OFFERED TO HAVE A FIELD TECH PERSON COME DRIVE MY CAR. I CALLED NATIONAL AGAIN AND THEY SEEM TO BE "MEDIATING" THIS WITH BUTLER. I FOUND A REPORT FROM CONSUMERAFFAIRS.COM THAT THIS VERY SIMILAR ISSUE WAS OCCURRING BACK IN 2008 AND THEY CALLED IT "TRACTION CONTROL". NO ONE FROM TOYOTA HAS TOLD ME THIS. I WANT IT FIXED OR A DIFFERENT CAR. I HAVE A TEENAGE WITH A PERMIT AND IF HE WAS DRIVING THIS AND IT OCCURRED, HE WOULD PROBABLY RUN INTO SOMEONE BECAUSE IT TAKES YOU BY SURPRISE. I DO FEAR HIM DRIVING IT DUE TO HIS INEXPERIENCE AND I FRANKLY AM CONCERNED AND AM VERY CAUTIOUS AS A RESULT. *TR

AT ABOUT 7:45 AM SUNDAY MAY 23, I WAS DRIVING WEST ON HAMBURG TURNPIKE IN WAYNE, GENTLY ACCELERATING TO GET BETTER MILEAGE, THE LIGHT AT BERDAN AVE AND HAMBURG HAD JUST TURNED GREEN, SO I ACCELERATED SLOWLY TO ABOUT 40 MPH. AT THIS POINT, I HEAR A SHRIEKING BEEP AND THE CAR LURCHES FORWARD AS THE BRAKES WERE APPLIED. THE DASH LIGHTS UP WITH THE USUAL MESSAGE SQUARE AND THE WORD BRAKE! IN THE BOX. I LOOK IN ALL DIRECTIONS AND SAW NOTHING UNTIL I BOUNCED OVER THE CONSTRUCTION PLATES. THE BOX WAS GONE, AND THE CAR RESUMED NORMAL OPERATION. I WAS PUZZLED. I THOUGHT IT COULD BE THE PLATES. I CHECKED WITH MY SON AND HE REMINDED ME THAT IN THE MODEL 5 WE HAVE RADAR CRASH AVOIDANCE. UPON FURTHER REVIEW I WANTED MORE INFORMATION. I TOOK MY SON, AND A CAMERA, AND DROVE THE ROUTE AGAIN. EUREKA! IN ALL THREE ATTEMPTS, THE BRAKES WERE APPLIED. I HAVE PICTURES OF THE DASH, AND THE PLATES. DID THE CAR PERFORM CORRECTLY? THE SECOND PLATE IS NOT FLUSH TO THE ROAD AND STICKS OUT TO THE LEFT. I THINK OTHER DRIVERS NEED TO BE AWARE OF THIS POSSIBILITY SO THEY DO NOT PANIC WHEN IT HAPPENS. THE CRASH AVOIDANCE SYSTEM COULD HAVE BEEN DOING ITS JOB CORRECTLY. I CONTACTED WAYNE POLICE ABOUT THE INCIDENT AND THE DISPATCHER SAID AFTER CONSULTATION ' IT IS A COUNTY ROAD, CALL THE PASSAIC COUNTY ROAD DEPARTMENT. MY CAR COMPUTER WILL HAVE RECORDED ALL 3 INCIDENTS. THE THIRD WAS NOT AS BIG A JOLT BECAUSE THE DRIVER AHEAD OF ME HAD SLOWED CONSIDERABLY WHEN HE SAW THE PLATES. THERE IS A WARNING SIGN THAT IS BEYOND THE PLATES IN THE PICTURE. LET ME KNOW IF ANYONE IN SERVICE IS INTERESTED IN THE INFORMATION SINCE THIS IS A NEW FEATURE AND I KNOW AS A COMPUTER PROGRAMMER OF SOME 40+ YEARS THAT A SYSTEM DOES NOT ALWAYS GET TESTED FOR ALL POSSIBLE EVENTS. I ALSO CANNOT BELIEVE THAT UNLIKE NYC WHERE THERE MUST BE NO BUMPS OR RAISED PLATES DURING CONSTRUCTION THAT PASSAIC COUNTY ALLOWS THESE PLATES TO BE INSTALLED WITHOUT BEING FLAT OR ASPHALTED AROUND THE EDGE. *TR

AFTER TAKING MY 2010 PRIUS IN FOR THE RECALL FIX ON APRIL 1, 2010, THE VEHICLE CONTINUED TO EXHIBIT SAFETY DEFECTS. I REPORTED THIS TO THE DEALER WHO REPORTED IT TO CORPORATE AND ARRANGED FOR A FIELD TECH TO ANALYZE THE VEHICLE ON APRIL 13TH. THEY SAID WE WOULD HEAR FROM TOYOTA WITH IN TWO WEEKS I NEVER HEARD BACK FROM THE DEALER SO I CALLED THE DEALER LAST WEEK. DEALER HAD NOT HEARD BACK. I FILED UNDER THE LEMON LAW.

WHILE DRIVING ON I-430 IN WEST LITTLE ROCK YESTERDAY, I HAD THE CRUISE CONTROL SET ON 65 MPH. AS I APPROACHED SLOWER TRAFFIC AHEAD, I SLOWED THE CAR TO 60MPH USING THE BRAKES. I ASSUMED THAT THE CRUISE CONTROL ON MY CAR HAD AUTOMATICALLY DISENGAGED AT THIS POINT AND I LET OFF THE BRAKES. THE CRUISE CONTROL THEN CAUSED THE CAR TO ACCELERATE BACK UP TO 65MPH AS IT NEVER DISENGAGED BY USING THE BRAKES. THIS WAS ESPECIALLY DANGEROUS SINCE IT HAPPENED NEAR THE CREST OF A HILL AND CAUSED MY VEHICLE TO NO LONGER BE AT A SAFE FOLLOWING DISTANCE BEHIND THE SLOWER CAR IN FRONT OF ME. *TR

ON 4/20/10 @ 12:50 PM, MY PRIUS ACCELERATED DANGEROUSLY AS I WAS COMING TO A COMPLETE STOP ON A SLIGHT INCLINE. THE CAR SHOT FORWARD THROUGH A RED LIGHT ON A BUSY BALTIMORE ARTERIAL. I WAS BRAKING THE CAR AND TRYING TO TURN IT TO AVOID HITTING A CONCRETE WALL OR CARS IN THE OPPOSITE LANES. I TURNED VERY SHARPLY,UNABLE TO BRAKE THE CAR; I FEARED IT MAY ROLLOVER. MY FOOT WAS ON THE BRAKE THE WHOLE TIME. I HOPPED A CURB ON THE MEDIAN AND CLIPPED A TRAFFIC SIGN. I THEN PARKED THE CAR AND PHONED THE POLICE. IT WAS AMAZING NO ONE GOT HURT OR KILLED. SINCE THIS INCIDENT OCCURRED AFTER TOYOTA SAID THEY FIXED THE PROBLEM, I DO NOT TRUST THEM OR MY CAR. I WANT A REFUND FOR THIS CAR, I WILL NOT DRIVE IT AGAIN:IT IS A DEATH MACHINE. *TR

2010 PRIUS WITH ABOUT 14,500 MILES DRIVING ON SMOOTH, WET, PAVED ROAD 20 MILES AN HOUR ON A CURVE. NEITHER FOOT WAS NOT ON A PEDAL - CAR WAS COASTING FOR SEVERAL SECONDS AS EXPECTED, SLOWLY DECELERATING. IN THE MIDDLE OF THE CURVE, WITH BOTH FEET STILL NOT ON EITHER GAS OR BRAKE, I FELT AND HEARD A NOTABLE SURGE OF HARD ACCELERATION DESPITE BOTH FEET BEING OFF THE GAS AND BRAKE. MY WIFE IN THE PASSENGER SEAT ALSO NOTICED THE SURGE. I IMMEDIATELY BRAKED HARD. THE CAR SLOWED SAFELY, AND THE UNREQUESTED ACCELERATION SEEMED TO STOP AS SOON AS I ENGAGED THE BRAKE PEDAL. NOTHING WAS TOUCHING THE ACCELERATOR BEFORE THE SURGE, DURING THE SURGE, OR WHEN THE SURGE ENDED AS I BRAKED - NOT A FLOOR MAT, NOT A STRAY OBJECT, NOT MY FOOT. THIS IS THE FIRST TIME WE HAVE EXPERIENCED THIS EXACT PATTERN OF SYMPTOMS. IN THE PAST, BEFORE THE BRAKE SOFTWARE RECALL WAS DOWNLOADED TO OUR CAR, WE HAD MANY EPISODES OF TEMPORARY LOSS OF BRAKING POWER ON BUMPY ROADS. AT LEAST ONE OF THOSE PRIOR EPISODES HAD UNEXPLAINED ACCELERATION ACCOMPANY THE TEMPORARY BRAKING FAILURE ON A BUMPY ROAD. TODAY'S INCIDENT WAS VERY DIFFERENT - I WAS NOT BRAKING, AND THE ROAD WAS NOT BUMPY. NOTE THAT THE 2010 PRIUS IS NOT ON THE RECALL LISTS FOR THE ACCELERATOR MODIFICATIONS, AND THAT A STICKY ACCELERATOR WOULD NOT EXPLAIN THIS BEHAVIOR. *TR

WHEN APPLYING NORMAL PRESSURE TO THE BRAKES, ON SEVERAL OCCASIONS THE BRAKES HAVE LOCKED VIOLENTLY, SENDING ME AND MY PASSENGERS AGAINST OUR SEAT BELTS. TOYOTA CLAIMED THAT THE RECALL MAY MAKE THAT BETTER. IT HAS NOT. THIRDLY, I REPORTED LAST WEEK TO TOYOTA THAT THE CAR HAS ON OCCASION SHAKEN VIOLENTLY AND MADE A LOUD CLANKING NOISE (LIKE A WASHING MACHINE OFF BALANCE) UPON START UP, CAUSING ME TO JUMP OUT F THE CAR FOR FEAR OF IT BLOWING UP.

MY 2010 PRIUS WAS "REPAIRED" LAST MONTH. IT INTERMITTENTLY ACCELERATES WITHOUT MY PROMPTING AFTER HITTING A BUMP. THIS ACCELERATION IS AS INTENSE AS THE CAR SEEMS TO ALLOW, AS IF THE PEDAL WERE TO THE FLOOR OR WORSE, AND PERSISTS FOR AT LEAST ONE SECOND AND HAS NOT SUBSIDED SINCE THE ABS ACTUATOR ECU WAS UPDATED IN THE RECALL APPOINTMENT. THIS ACCELERATION IS TERRIFYING AS IT CAN'T BE ANTICIPATED AS IT DOES NOT HAPPEN EVERY TIME I HIT A BUMP, AND CAN'T BE SUPPRESSED BY THE BRAKING SYSTEM. I HAVE ON SEVERAL OCCASIONS BEEN SAFELY COASTING TO A STOP WITH THE BRAKES ON AND EXPERIENCED THIS PROBLEM. IN A FEW CASES THIS ACCELERATION ALMOST CAUSED ME TO HIT THE CAR IN FRONT OF ME AT STOP LIGHTS.

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 RESORTED TO USING THE SAFETY CONNECT SOS BUTTON. THERE WERE NO DOORS AJAR AND NO INDICATION OF THE CAUSE. WHILE TALKING WITH THE PERSON WHO RESPONDED I PERIODICALLY CONTINUED TO TRY SHIFTING FROM PARK TO DRIVE; AFTER SEVERAL ATTEMPTS THE CAR RESPONDED. *TR

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 THE ABS FIX FOR WHICH THE 2010 PRIUS IS BEING RECALLED TO BE COMPLETED AS SOON AS POSSIBLE. AND, I WOULD LIKE FOR THE DAMAGE TO MY CAR TO BE REPAIRED. *TR

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.

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

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.

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

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

2010 TOYOTA PRIUS CRUISE CONTROL CAUSED UNINTENDED ACCELERATION WHEN RE-ENGAGED. AFTER DISENGAGING CRUISE CONTROL SET TO 65 AND COASTING AT 50 FOR A WHILE WHEN THE CRUISE CONTROL WAS RE-ENGAGED THE VEHICLE RESUMED IN EXCESS OF 70 MPH BEFORE I DISABLED CRUISE CONTROL. DATE OF INCIDENT IS APPROXIMATE. I DIDN'T THINK MUCH OF THE FAILURE AT THE TIME OTHER THAN THAT THE CRUISE CONTROL WAS BEHAVING ODDLY (I HAVE AVOIDED CRUISE CONTROL ON THIS CAR SINCE). IN LIGHT OF THE CURRENT INVESTIGATION I THOUGHT I WOULD SUBMIT A REPORT. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE VEHICLE ACCELERATED ON ITS OWN WHILE DRIVING 30 MPH, WHEN THE CONTACT ATTEMPTED TO STOP AT AN INTERSECTION. THE FAILURE OCCURRED SIX TIMES. THE DRIVER STATED THAT WHEN THE FAILURE OCCURRED THEY WERE UNABLE TO STOP THE VEHICLE. THE TOYOTA DEALER STATED THAT THERE WAS NOTHING WRONG WITH THE VEHICLE. THE FAILURE HAS OCCURRED FOR OVER 9 MONTHS. THE CONTACT HAS NOT RECEIVED A RECALL NOTICE FROM THE DEALER BUT SHE IS AWARE OF AN EXISTING RECALL. THE FAILURE MILEAGE WAS 2,500. THE CURRENT MILEAGE WAS 5,500.

WE BOUGHT A 2010 TOYOTA PRIUS II IN 7/2009. WE HAVE ON MULTIPLE OCCASIONS EXPERIENCED A BRIEF ACCELERATION OF THE CAR WHEN OUR FOOT IS APPLYING THE BRAKE PEDAL TO TRY AND SLOW DOWN. MOST OF THESE OCCASIONS HAVE HAPPENED WHEN GOING OVER BUMPS AND OFTEN WHEN TURNING A CORNER. WE DID HAVE THE SOFTWARE UPGRADE THAT WAS RECOMMENDED BY THE RECALL JUST 2 WEEKS AGO. STILL, MY WIFE EXPERIENCED THE SAME PROBLEM AGAIN WHEN COMING HOME IN THE CAR A FEW DAYS AGO. IT HAS HAPPENED IN TOTAL ABOUT 5 TIMES SINCE WE BOUGHT THE CAR IN 7/09 AND HAVE DRIVEN ABOUT 10,000 MILES. ON ONE OCCASION LAST YEAR I ALMOST LOST CONTROL OF THE CAR GOING AROUND A CURVE BECAUSE OF THE ACCELERATION. I DON'T THINK THIS IS SIMPLY A BRAKE ISSUE, THE CAR ACTUALLY SEEMS TO ACCELERATE BRIEFLY. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE DRIVER STATED THAT SHE RECENTLY HAD A RECALL REPAIR PERFORMED ON HER VEHICLE FOR THE ACCELERATION; HOWEVER, SHE CONTINUED TO EXPERIENCE THE IDENTICAL FAILURE. WHEN SHE DROVE OVER A BUMP IN THE ROAD, THE VEHICLE ACCELERATED ON IT'S OWN. SHE CALLED THE SERVICE MANAGER AND SHE IS WAITING FOR A RETURN CALL FROM HIM. THE FAILURE MILEAGE WAS 500. THE CURRENT MILEAGE WAS 8,000.

Mileage: 4,700

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING IN REVERSE OUT OF THE GARAGE HE EXPERIENCED AN UNINTENDED ACCELERATION AT LEAST THREE TIMES WITHIN A MONTH. ALSO WHEN HE WAS DRIVING AT 5 MPH AND COMING TO A STOP, THE VEHICLE LUNGED FORWARD AND AS HE JAMMED HIS FOOT HARDER ON THE BRAKES, THE VEHICLE KEPT GOING . THE VEHICLE WAS TAKEN TO THE DEALER ON TWO OCCASIONS; HOWEVER, DURING A TEST DRIVE THEY WERE UNABLE TO DUPLICATE, DIAGNOSE OR REPAIR THE FAILURE. THE TOYOTA MANUFACTURER HAS NOT BEEN CALLED. THE FAILURE MILEAGE WAS 1,700.

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS HYBRID. HE STATED THAT WHEN THE GASOLINE ENGINE WAS ENGAGED IN ANY GEAR, INCLUDING THE PARK POSITION, THE VEHICLE WOULD SURGE. HE ALSO STATED THAT UPON TURNING THE GASOLINE ENGINE OFF, THE VEHICLE WOULD MOMENTARILY ROLL BACKWARDS. THIS WOULD OFTEN OCCUR WHILE ANY ELECTRICAL COMPONENT OF THE VEHICLE WAS UTILIZED, TO INCLUDE THE HEATER, DEFROST AND RADIO. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THEY COULD NOT DUPLICATE THE FAILURE. THE DEALER STATED THAT THE VEHICLE WAS OPERATING AS IT WAS DESIGNED. THERE WERE NO REPAIRS MADE TO THE VEHICLE TO DATE. THE FAILURE MILEAGE WAS 200 AND THE CURRENT MILEAGE WAS 1,398.

MY 2010 PRIUS HYBRID ACCELERATES FROM ELECTRIC TO FUEL MODE ON ITS OWN. I HAVE TAKEN IT TO TOYOTA DEALERSHIP 2 TIMES FOR PROBLEM. TOYOTA SERVICEMEN STATES IT WILL OCCASIONALLY DO THAT DEPENDING ON THE MODE THE VEHICLE IS IN. I FIND IT TO BE VERY DANGEROUS AS I DO NOT HAVE CONTROL WHEN IT WILL HAPPENS. SERVICEMEN ALSO SAID THAT IS WHY THERE IS AN ALARM BEEPING TO LET DRIVER KNOW IT IS BACKING UP. THAT DOES NOT MAKE SENSE THE ALRM IS NOT GOING TO CONTROL THE MODE THE VEHICLE IS IN. IT IS A SAFETY ISSUE SEVERAL TIMES I HAVE ALMOST HIT OTHER VEHICLES OR PEDESTRIANS WHEN BACKING UP. I NOW TRY NOT TO USE REVERSE TO AVOID A POSSIBLE ACCIDENT. PLEASE LET ME KNOW IF OTHER VEHICLES HAVE SIMILAR PROBLEMS. *TR

WHEN SHE APPLIED THE BRAKES AND THE VEHICLE STARTED TO STOP BUT THEN IT LUNGED FORWARD AND ACCELERATED ON IT'S OWN WHILE HER FOOT WAS ON THE BRAKE PEDAL. THE DRIVER STATED THAT THE VEHICLE THEN CAME TO A STOP AFTER HER FOOT REMAINED ON THE BRAKE PEDAL. THE DRIVER DID NOTIFY THE DEALER OF THE FAILURE. THE VIN WAS UNKNOWN. THE FAILURE MILEAGE AND CURRENT MILEAGES WERE 10,000.

INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) FEBRUARY 15, 2010 AT 3:29 PM I SPOKE TO [XXX] AT TOYOTA 1-800-331-4331 ABOUT PROBLEMS I'VE EXPERIENCED WITH MY 2010 PRIUS. I TOLD HER ABOUT THE CRUISE CONTROL DANGER, WHERE THE CAR HAD BEEN GOING ALONG NICELY ON CRUISE, BUT SUDDENLY RAPIDLY ACCELERATED WHEN, ON AUGUST 11, 2009, I WAS ON THE TRIP BETWEEN NEW JERSEY AND ILLINOIS COMING THROUGH THE TENNESSEE/KENTUCKY AREA. I HAD BEEN TRAVELING AT ABOUT 65MPH ON CRUISE AND IT RAPIDLY ACCELERATED TO OVER 80MPH AND I PANICKED WHILE TRYING TO GET IT TO SLOW DOWN. I TRIED SLOWING IT DOWN USING THE CRUISE BUTTON, THEN DEPRESSED THE CRUISE OFF BUTTON. DIDN'T WORK. IT DID NOT RESPOND IMMEDIATELY TO THE BRAKE UNTIL I BRAKED REALLY HARD. THEREFORE, MY DRIVING IT WAS SEVERELY LIMITED TO DRIVING AT VERY LOW SPEEDS IN TOWN. OTHER UNINTENDED ACCELERATION HAS OCCURRED EVEN WHEN NOT USING THE CRUISE. THE CAR BOLTED FORWARD NUMEROUS TIMES ON A BUMPY SECTION OF ROAD ON MY ROUTE HOME FROM WORK; IT HAPPENED OFTEN ENOUGH THERE THAT I COMPENSATED BY TAKING A DIFFERENT ROUTE. EFFORTS TO STOP THE FORWARD LUNGE INCLUDED BRAKING WITH NO RESPONSE, USING THE KNOB TO SHIFT TO A DIFFERENT SETTING, AND SCRAMBLING TO FIND THE [XXX] BUTTON TO PRESS PARK. SOMETHING FINALLY STOPPED IT, BUT I DON'T KNOW WHAT. THE NEXT SCARE OCCURRED AFTER IT SNOWED. I DROVE SLOWLY ON THE PLOWED ROAD, BUT WHEN THE CAR ENCOUNTERED SNOWY LUMPS IT RAPIDLY ACCELERATED LUNGING FORWARD AGAIN. MY ATTEMPTS TO STOP CAUSED ME TO SKID DANGEROUSLY INTO ONCOMING TRAFFIC LANE. I PARKED THE CAR IN THE GARAGE AND HAVE NOT DRIVEN IT AGAIN IN WELL OVER A MONTH DUE TO THE DANGER. IN FEBRUARY, MY CO-WORKER[XXX] URGED ME NOT TO DRIVE THE CAR BECAUSE SHE HAD HEARD ABOUT A RECALL AND WAS AFRAID FOR ME, BUT I HAD ALREADY PARKED IT BY THEN ' KNOWING SOMETHING WAS WRONG WITH IT. IT HAS NOT BEEN DRIVEN SINCE PRIOR TO MY LEARNING THAT OTHERS HAVE HAD SIMILAR EXPERIENCES ' SOME HAVE DIED OR BEEN INJURED AS A RESULT.

2010 TOYOTA PRIUS; WHEN SHIFTING INTO REVERSE IS SPORADICALLY DIFFICULT TO CONTROL ACCELERATION. LIFTING MY FOOT OFF THE BRAKE A TINY AMOUNT CAUSES THE CAR TO FEEL LIKE IT IS "SURGING" BACKWARD. THE CAR IS CONTROLLABLE, BUT IT IS A VERY DIFFERENT EXPERIENCE FROM BEING IN REVERSE MOST OF THE TIME. SHIFTING TO PARK AND BACK TO REVERSE SEEMS TO MAKE IT GO AWAY. THIS HAS HAPPENED TO ME 4 TIMES SINCE I BOUGHT THE CAR IN AUGUST 2009. *TR

Mileage: 6,100

OUR 2010 PRIUS WAS EXPERIENCING SURGING OVER BUMPS, WE HAD IT RE-PROGRAMMED LAST WEEK AND TODAY WE EXPERIENCED THE SURGE AGAIN WHEN WE WENT OVER A BUMP, JUST LIKE BEFORE. *TR

IN MY 2010 PRIUS, THE VEHICLE RANDOMLY ACCELERATES WHEN THE CRUISE CONTROL IS DISENGAGED. THIS HAPPENS EVERY 10TH OR 15TH TIME OF DISENGAGEMENT. WHEN THE BRAKES ARE APPLIED HARDER THE VEHICLE SLOWS PROPERLY. THE UNEXPECTED ACCELERATION IS VERY DANGEROUS IN TRAFFIC. THE VEHICLE HAS BEEN CHECKED BY THE DEALER AND I WAS TOLD THAT NOTHING IS WRONG. I CALLED FOR A SECOND TIME AND WAS TOLD THE PROBLEM IS NOT ON THE RECALL LIST. I WILL TAKE IT IN ANYWAY NEXT WEEK. *TR

2010 PRIUS PURCHASED IN AUGUST 2009. SURGE WHEN APPLYING BRAKES. OCCURRED 4 TIMES INCLUDING 2/15/2010. HAS OCCURRED IN SAME PLACE 3 TIMES. EACH TIME THERE WERE POTHOLES. WHEN THEY WERE FIXED, DID NOT HAPPEN UNTIL THEY RETURNED. COMPLAINED TO TOYOTA DEALER AND WAS TOLD THIS WAS NORMAL WHEN HYDRAULIC AND ELECTRONIC BRAKES EXCHANGE. I SUGGESTED IT WAS A DANGEROUS NORMAL. NO DAMAGE OR INJURY IN ANY CASE. WAS ALWAYS ABLE TO PUSH HARDER ON BRAKE TO STOP CAR. STUNS YOU WHEN IT HAPPENS BECAUSE IT IS NOT NORMAL.

USING CRUISE CONTROL FEATURE,WHEN I HIT THE BRAKE FOR SPLIT SECOND THE CAR SPEEDS UP BEFORE DISENGAGING CRUISE CONTROL THIS HAPPEN ALL THE TIME NOT ON JUST THE DATE BELOW. *TR

Mileage: 7,000

THIS PROBLEM HAS EXISTED SINCE THE VEHICLE WAS PURCHASED. CRUISE CONTROL EITHER DOES NOT FUNCTION AT ALL OR FAILS TO FUNCTION CORRECTLY. SOMETIMES THE CRUISE CONTROL WILL NOT ENGAGE. SOMETIMES THE CRUISE CONTROL WILL ENGAGE PROPERLY, BUT AFTER APPLYING THE BRAKES (AND DISENGAGING THE CRUISE CONTROL) THE CRUISE CONTROL CANNOT BE REENGAGED. TWO OPERATIONS WILL CAUSE THE CRUISE CONTROL TO BEGIN FUNCTIONING PROPERLY AGAIN: 1) TURN THE VEHICLE OFF; 2) PUT THE SHIFT LEVER INTO THE NEUTRAL POSITION, THEN BACK INTO DRIVE. RETURNED VEHICLE TO DEALER THREE TIMES FOR REPAIR. THEY DID NOT FIX THE MALFUNCTION DURING ANY OF THE THREE REPAIR VISITS. THEIR FINAL RESPONSE WAS TO CLAIM THAT THE VEHICLE WAS "FUNCTIONING AS DESIGNED". *TR

Mileage: 500

I HAVE A 2010 PRIUS. OCCASIONALLY WHEN I GO OVER A BUMP (POTHOLE, TRAIN TRACK, ROUGH ROAD) MY CAR FEELS LIKE IT JOLTS FORWARD FOR A FEW SECONDS. THIS HAPPENS WHEN I AM NOT HITTING THE BRAKES SO I DON'T THINK IT IS COVERED BY THE ANTI-LOCK BRAKING RECALL. IT IS DIFFICULT TO REPLICATE THIS AND I HAVEN'T REPORTED IT TO THE DEALER BECAUSE OF THIS, BUT IT HAPPENS ABOUT 1-2/WEEK. IT COULD BE A PROBLEM IN A TRAFFIC SITUATION WHERE CARS ARE FOLLOWING CLOSELY. *TR

Mileage: 1,000

I HAVE A 2010 PRIUS. WE HAVE HAD THE PROBLEM WITH THE BRAKES WHEN WE GO OVER A BUMP. IN ADDITION, IF I AM DRIVING IN CRUISE CONTROL AND HAVE TO PUT MY FOOT ON THE BRAKES, THERE IS A BRIEF FEELING OF ACCELERATION SO INSTEAD I HAVE GOTTEN USED TO TURNING OFF THE CRUISE CONTROL BEFORE PUTTING MY FOOT ON THE BRAKES THEREBY DELAYING BRAKING FOR A BRIEF MOMENT. *TR

I OWN A TOYOTA 2010 PRIUS. I COMPLAINED TO THE DEALERSHIP WHERE I BOUGHT MY CAR IN JULY AT MY FIRST SERVICE/OIL CHANGE ABOUT A SUDDEN SURGE IN SPEED WHILE DRIVING OVER BUMPY SURFACES. I PRESENTED THEM WITH INTERNET INFORMATION I HAD COPIED FROM CONSUMERS HAVING THE SAME PROBLEM BUT THEY WOULD NOT TAKE THEM FROM ME. THEY SERVICED THE CAR, DROVE IT AND RETURNED IT TO ME SAYING THEY FOUND NO PROBLEMS AND THAT I WAS THE ONLY PERSON WHO HAD EVER COMPLAINED ABOUT IT. THEY SAID THEY KNEW OF NO OTHER SIMILAR COMPLAINTS. I ASKED THEM TO PUT ON MY BILL THE FACT THAT THIS WAS HAPPENING TO MY CAR SO THAT IT WOULD BE DOCUMENTED FOR THE FUTURE. THEY DID NOT SEEM AT ALL CONCERNED AT THE TIME. IT REMAINS AN ONGOING PROBLEM WHEN I DRIVE. *TR

TO THE NHTSA: I AM AN OWNER OF A 2010 TOYOTA PRIUS THAT I PURCHASED IN JUNE 2009. SINCE OWNING THE VEHICLE, I HAVE HAD ABOUT A HALF-DOZEN TO A DOZEN OCCURRENCES OF THE SAME PROBLEM. AT LOW SPEEDS, WHEN THE REAR WHEEL HITS A BUMP, FOR A SPLIT-SECOND THE CAR FEELS LIKE THERE IS A BURST OF ACCELERATION AND IS OUT OF CONTROL. THIS LASTS ONLY A SPLIT-SECOND. I SAW ANOTHER CONSUMER IN A NEWS ARTICLE ABOUT THE PRIUS BRAKE ISSUE DESCRIBE IT THE EXACT SAME WAY. I ACTUALLY MENTIONED THIS TO MY DEALER (BERNARDI TOYOTA, FRAMINGHAM, MA) WHEN I BROUGHT THE CAR IN FOR THE 5,000 MILE SERVICE A MONTH OR SO AGO. THE SERVICE DEPT TOLD ME THAT THE BEHAVIOR IS NORMAL FOR THE HYBRID VEHICLES, AND KNOWN BY TOYOTA -- NO FIX OR ADJUSTMENT RECOMMENDED. THIS SEEMED LIKE AN ODD RESPONSE, BUT BECAUSE THEY TOLD ME THERE WAS NO SAFETY ISSUE, I LEFT IT AT THAT. I AM PROVIDING MY EXPERIENCE TO AID THE NHTSA APPLY PRESSURE ON TOYOTA TO FIX THIS PROBLEM IN THE PRIUS. *TR

I HAVE EXPERIENCED TWO PROBLEMS WITH MY 2010 PRIUS V THAT I PURCHASED LAST SUMMER. FIRST, ON APPROXIMATELY 6-8 OCCASIONS, MY CAR HAS NOT STOPPED IMMEDIATELY WHEN I APPLIED THE BRAKES. THIS OCCURRED 3-4 TIMES WHEN I APPROACHED A STOP SIGN ON A ROAD BETWEEN MY HOME AND CHURCH. THE SURFACE OF THE ROAD APPROACHING THE STOP SIGN HAD BEEN SCRAPED AND ROUGHENED TO GET READY FOR RE-PAVING. AS I APPROACHED AND APPLIED THE BRAKES, MY CAR SURGED FORWARD FOR ABOUT A SECOND, BUT I WAS ABLE TO STOP. THIS HAPPENED 3-4 TIMES IN OTHER LOCATIONS, AS WELL. IT IS AN INCREDIBLY STRANGE AND HELPLESS SENSATION. THIS PROBLEM WAS PROBABLY NOTED BETWEEN LATE AUGUST 2009 AND LAST OCCURRED ABOUT THREE WEEKS AGO. EVEN THOUGH I WAS FORCED TO PUT AN EXACT DATE IN THE FIELD BELOW, I HAVE NO IDEA NOW WHEN THE EXACT DATES WERE IN WHICH THIS BRAKING ISSUE OCCURRED. WHEN I BROUGHT MY CAR TO THE DEALER FOR ITS FIRST OIL CHANGE, I DESCRIBED WHAT HAD HAPPENED BUT WAS TOLD THIS HAD NOTHING TO DO WITH THE OTHER PROBLEMS THAT HAD BEEN IDENTIFIED IN THE MEDIA AS TO OTHER CARS. THE PERSON AT THE SERVICE DESK JUST KIND OF IGNORED MY COMMENTS AND WAS NOT INTERESTED IN HEARING ABOUT THE BRAKING ISSUE FURTHER. THE SECOND PROBLEM I HAVE EXPERIENCED IS THAT WHEN USING THE CRUISE CONTROL ACCELERATE FUNCTION THE CAR JUST CONTINUED ACCELERATING EVEN THOUGH I WAS NO LONGER TURNING THE CRUISE FUNCTION LEVER. THIS STOPPED WHEN I APPLIED MY BRAKES. IT DID CAUSE ME TO STOP USING THE CRUISE CONTROL DURING THAT TRIP THOUGH. THE CRUISE CONTROL ISSUE PROBABLY OCCURRED LAST AUGUST IN I-5. *TR

2010 TOYOTA PRIUS, PURCHASED NOV. 2009. USING CRUISE CONTROL, THE CAR ACCELERATED QUICKLY ON IT'S OWN WHEN I ATTEMPTED TO CHANGE SPEED BY USING THE CRUISE CONTROL LEVER ON THE STEERING WHEEL. HAPPENED TWICE, THEN I STOPPED EXPERIMENTING FOR REASONS OF SAFETY. THE PROBLEM IS IDENTICAL TO THE ONE DESCRIBED BY STEVE WOSNIAK IN PUBLIC TWO WEEKS AGO--ONE THAT GOT A LOT OF PRESS. ACCELERATION STOPPED WHEN BRAKE PEDAL WAS TAPPED OR CRUISE CONTROL WAS TURNED OFF. *TR

THE BRAKES ON MY 2010 TOYOTA PRIUS AT TIMES DO NOT ENGAGE IMMEDIATELY. IT MAY BE NECESSARY AT THOSE TIMES TO DEPRESS THE BRAKE PEDAL BY 1/3RD BEFORE BRAKING BEGINS. THERE IS A SIMILAR DELAY WHEN BRAKING IS USED TO TURN OFF CRUISE CONTROL. NEITHER OF THESE HAVE CAUSED AN ACCIDENT, BUT IN BOTH CASES THERE IS SOME RISK.

1. I WAS DRIVING IN SAN FRANCISCO, CA ON CITY ROADS. IN BOTH EVENTS, I WAS BRAKING TO MINIMIZE THE IMPACT OF DRIVING OVER POTHOLES OR UNEVEN PAVEMENT (HOLES THAT WERE RECENTLY FILLED WITH ASPHALT) SEEN AHEAD. 2. WHEN THE BRAKES WERE APPLIED, THERE WAS A BRIEF, MOMENTARY SURGE IN POWER FOLLOWED BY NORMAL BRAKING. ON ONE OCCASION, A PASSENGER RIDING IN THE FRONT PASSENGER SEAT ALSO NOTICED THE SURGE AND COMMENTED ON IT. 3. NO CORRECTIVE ACTION HAS BEEN TAKEN SO FAR. AWAITING NEWS ON A POSSIBLE RECALL AND INSTRUCTIONS FROM CAR MARKER ON CORRECTIVE ACTIONS TO BE TAKEN. *TW

2010 PRIUS, LESS THAN 5000 MILES. ON THE I-5 (CA) GOING TO SAN FRANCISCO ON 12-24-09. ON A SLIGHT/MODERATE DOWNGRADE WITH CRUISE SET AT 70 MPH, THE CAR WAS BRAKING HARD AND WAS OVER 100 MPH BEFORE I REALIZED WHAT THE NOISE WAS - AND IMMEDIATELY TOOK IT OUT OF CRUISE AND BRAKED. IT CAME UNDER CONTROL. ON OR ABOUT 12-31-09 I WAS UNABLE TO ENGAGE CRUISE ON THE FREEWAY BUT THE FOLLOWING DAY IT ENGAGED NORMALLY. *TW

Mileage: 4,790

SOON AFTER I GOT MY 2010 PRIUS IN AUGUST, I EXPERIENCED A BRAKING PROBLEM. THIS HAS HAPPENED ABOUT 8 MORE TIMES SO FAR. WHILE BRAKING AS I SLOWLY APPROACH A STOP SIGN OR LIGHT, IF I SIMULTANEOUSLY GO OVER A BUMP OR BREAK IN THE ROAD, THE CAR WILL LURCH FORWARD A COUPLE OF YARDS REQUIRING ME TO PUSH HARDER ON THE BRAKE WHICH THEN STOPS THE CAR. THIS PROBLEM HAS ALSO HAPPENED 2 TIMES IN THE LAST WEEK WHILE DRIVING SLOWLY AND THEN BRAKING WHEN I ENCOUNTER ICE ON THE ROAD. LUCKILY, NO CARS HAVE BEEN DIRECTLY IN FRONT OF ME WHEN THIS HAS HAPPENED. I HAVE NOT REPORTED THIS TO TOYOTA BECAUSE I HAVE NOT YET SERVICED MY CAR. *TW

PRIUS PURCHASED NOV 2009: AT LEAST INCIDENTS OF CAR LURCHING FORWARD SIGNIFICANTLY AND MOMENTARY SENSE OF LOSS OF CONTROL WHEN BRAKING ON UNEVEN SURFACE. OCCURED IN DEC 09,JAN 10, AND FEB 10. HAD A PEDESTRIAN BEEN CROSSING ILLEGALLY, THE PERSON COULD'VE BEEN HIT BEC I COULD NOT PREVENT OR CONTROL THAT LURCHING. THIS IS A DANGEROUS SITUATION. I FEEL I CANNOT DRIVE MY CAR SAFELY. I NEED MY CAR FOR WORK. I PHONED MY TOYOTA DEALER WHO SAID TO BRING IT IN FOR EVALUATION,BUT THEY SOUND TENTATIVE. I WANT A SOLUTION AND DON'T WANT TO BE MAKING NUMEROUS TRIPS FROM MY RURAL TOWN TO THE CITY DEALER FOR GUESSES. *CN

I PURCHASED A 2010 TOYOTA PRIUS IN AUGUST, 2009. DURING THE FALL, 2009, I EXPERIENCED TWO INCIDENTS, WHICH IN RETROSPECT, I THINK INVOLVED SUDDEN ACCELERATION. ON BOTH OCCASIONS, I WAS DRIVING HOME FROM WORK AND WENT OVER A SPOT ON THE ROAD WHICH, BECAUSE IT WAS DARK, I COULDN'T SEE FOR SURE, BUT WHICH FELT LIKE A POT HOLE. (I ALSO THINK IT MAY HAVE BEEN RAINING ON BOTH OF THESE OCCASIONS, ALTHOUGH I CAN'T RECALL FOR SURE). IMMEDIATELY AFTER HITTING WHAT I THINK WAS A POT HOLE, I FELT THE CAR SUDDENLY AND DRAMATICALLY ACCELERATE. BOTH TIMES I APPLIED THE BRAKES AND THE CAR STOPPED ACCELERATING. AT THE TIME, IT DID NOT OCCUR TO ME WHAT WAS GOING ON. BUT, NOW THINKING ABOUT IT, I THINK IT LIKELY THAT THE SUDDEN JOLT TO THE CAR, PERHAPS COMBINED WITH MOISTURE, CAUSED SOME TYPE OF ELECTRICAL MALFUNCTION, WHICH THANKFULLY, WAS SHORT-LIVED (OR AT LEAST STOPPED BY BRAKING). SHORTLY AFTER THESE INCIDENTS, I MENTIONED THEM TO MY WIFE. SHE REPORTED THAT SHE HAD EXPERIENCED VERY MUCH THE SAME THING ON A SEPARATE (I.E., A THIRD OCCASION) DRIVING OUR PRIUS. *CN

PROBLEM IS ONSET OF ACCELERATION WHEN BRAKES APPLIED IN 2010 PRIUS 4, PURCHASED AT ANTWERPEN TOYOTA, CLARKSVILLE, MD IN AUGUST 2010. PROBLEM HAS BEEN DETECTED 2 TIMES, WITHOUT ACCIDENT, BUT WITH SIGNIFICANT INCREASE IN ANXIETY. BOTH INCIDENTS WERE APPROACHING A STOP SIGN, AND SEEMED TO BE RELATED TO CHANGE IN ACCELERATION DUE TO RAPID BRAKING. FIRST INCIDENT IN SEPTEMBER 2009 WAS CONSIDERED A 'DRIVER ISSUE' SINCE I HAD OWNED THE PRIUS ONLY 1 MONTH. HOWEVER, SECOND INCIDENT IN NOVEMBER 2009 WAS CLEARLY NOT A DRIVER ISSUE, AND WAS INITIATED THE SAME WAY--STOPPING AT A STOP SIGN AFTER DRIVING AT HIGHWAY SPEEDS FOR SOME TIME. NEITHER INCIDENT INVOLVED A TRAFFIC ACCIDENT. *TR

THE CAR, A 2010 PRIUS, ACCELERATES FORWARD WHEN GOING OVER A BUMP IN THE ROAD OR A POTHOLE, AS THE BRAKE IS APPLIED. THE PROBLEM OCCURS AT AN UNPREDICTABLE FREQUENCY. THE CONSEQUENCES ARE THAT I LOSE CONTROL OF THE CAR'S SPEED. I HAVE REPORTED THIS PROBLEM TO MY DEALERSHIP SEVERAL TIMES SINCE PURCHASING THE PRIUS AND THEY HAVE FOUND NO PROBLEM, STATING THERE IS NOTHING TO FIX. I HAVE BEEN VERY CONCERNED ABOUT THE PROBLEM, EVEN BEFORE THE RECENT EVENTS IN THE NEWS ABOUT TOYOTA. HAD I KNOWN ABOUT THIS SITE, I WOULD HAVE REGISTERED THE COMPLAINT EARLIER. *TR

I HAVE NOTICED ISSUE WITH BRAKING. I REMEMBER IT HAD RAINED THE PREVIOUS NIGHT AND THE MORNING IT WAS FREEZING. I WAS DRIVING ON RT. 76 TO DROP MY SON OFF TO HIS WORK. ON SMALL STRETCH OF RT. 76 HAS THE 'CEMENT PATCH' - THOSE YOU TYPICALLY SEE ON A OVER PASS. FEARING ICING, I HIT THE BRAKE ONLY TO FEEL IT NOT RESPONDING. IN FACT, I FELT THE CAR SPEEDING UP. THE PATCH WAS JUST ABOUT 10-15 FT WIDE; THE MOMENT WE WERE OVER IT, I FELT THE BRAKES RESPOND. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS HYBRID. WHILE DRIVING APPROXIMATELY 20- 25 MPH ON A SLIGHTLY SNOW COVERED ROAD SURFACE THERE WAS PRESSURE APPLIED TO THE BRAKE PEDAL, FOLLOWED BY AN UNINTENDED ACCELERATION. THE DRIVER CONTINUOUSLY APPLIED PRESSURE TO THE BRAKE PEDAL; HOWEVER, THE VEHICLE FAILED TO SLOW DOWN WHILE PROCEEDING THROUGH AN INTERSECTION. AN OPPOSING VEHICLE CRASHED INTO THE FRONT PASSENGER SIDE AND THERE WERE NO INJURIES. THE POLICE WAS CALLED TO THE SCENE. THE VEHICLE WAS COMPLETELY DESTROYED AND TOWED TO A COLLISION CENTER. THE VIN WAS UNAVAILABLE. THE CAUSE OF THE FAILURE HAS NOT BEEN DETERMINED AT THIS TIME. THE FAILURE MILEAGE WAS 7,700. UPDATED 03/12/10. *LJ THE CONSUMER STATED WHEN HE APPROACHED A STOP SIGN WITH ADEQUATE DISTANCE TO STOP, PRESSURE WAS APPLIED TO THE BRAKE PEDAL. WHEN THE VEHICLE WOULD NOT STOP, HE HAD TO PRESS HARDER TO GET THE VEHICLE TO STOP. UPDATED 07/13/10.*JB

WHEN THE ROAD SURFACE IS SLIPPERY AND/OR UNEVEN (I.E, POTHOLE IS BEGINNING TO FORM), MY 2010 TOYOTA PRIUS HAS "SURGED" OR ACCELERATED SUDDENLY AT LOW SPEEDS UNDER 30 MPH, FOR NO APPARENT REASON OTHER THAN COMING INTO CONTACT WITH THE BUMPY/SLICK ROAD SURFACE. THIS SUDDEN ACCELERATION RESPONDS TO BRAKING AND HAS OCCURRED APPROXIMATELY 5-8 TIMES, WITH MORE FREQUENCY SINCE THE RAINY WEATHER BEGAN. THIS IS FRIGHTENING FOR A FEW BRIEF SECONDS, ESPECIALLY IN HEAVY TRAFFIC. AS A CONSEQUENCE, I TRY TO AVOID UNEVEN ROAD SURFACES BUT IN HEAVY RAIN CONDITIONS WHEN THE ROAD IS COVERED WITH WATER, POT HOLES AND BRAKES IN THE BLACKTOP ARE NOT AS EASILY VISIBLE AND ONCE I SWERVED TO MISS IT BY MOVING INTO THE NEXT LANE A LITTLE BIT AND A BIG TRUCK WAS MERGING INTO THE SAME LANE AT THE SAME TIME AND BLEW HIS HORN SO HARD IT SCARED ME EVEN MORE SO THAT I SWERVED BACK INTO MY LANE, NEARLY CAUSING AN ACCIDENT. I PLAN TO CONTACT MY DEALER TODAY ABOUT THIS ACCELERATION DEFECT. *TR

Mileage: 6,000

I'VE ALSO EXPERIENCED BRAKING ISSUES WITH THE PRIUS. THIS USUALLY HAPPENS GOING OVER POTHOLES, ROUGH ROAD, OR RAILROAD TRACKS WHEN BRAKING AT CERTAIN SPEEDS WHILE APPLYING THE BRAKES AT MODERATE FORCE. IT MOMENTARILY FEELS LIKE THE CAR IS ACCELERATING - IT'S QUITE DISCONCERTING. I'VE ALSO NOTICED VARIABILITY IN BRAKING DISTANCE EVEN ON SMOOTH DRY PAVEMENT WHERE I'VE HAD TO STEP HARDER ON THE BRAKES BECAUSE THE CAR WASN'T STOPPING AS EXPECTED. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING 2 MPH IN REVERSE AND REMOVING HIS FOOT FROM THE BRAKE, THE VEHICLE ACCELERATED ON ITS OWN. THE FAILURE HAS OCCURRED APPROXIMATELY 3 TO 4 TIMES. THE DEALER WAS CONTACTED AND HAD NOT RESPONDED WHEN THE COMPLAINT WAS FILED. THE CONTACT IS CONCERNED ABOUT THE SAFETY RISK INVOLVED AND DOESN'T FEEL SAFE DRIVING THE VEHICLE. NO REPAIRS WERE MADE TO THE VEHICLE. THE FAILURE MILEAGE WAS 2000. THE CURRENT MILEAGE WAS 5400.

I BOUGHT AT 2010 PRIUS ON 12/26/09 FROM THE VERY BEGINNING INTERMITTENTLY WHEN I GO TO STOP THE CAR WON'T STOP (MY CHEST TIGHTEN) ITS AS IF THE BACK OF THE CAR IS BEING PUSHED FORWARD EVEN THOUGH YOU HAVE YOUR FOOT ON THE BRAKE. YOU A GET A HESITATION AND THEN THE CAR STOPS. MY HUSBAND SAID IT WAS THE TRACTION CONTROL I WAS NOT USE TO IT.BUT THE TRACTION CONTROL LIGHT DOES NOT COME ON. ITS IS GETTING HARDER AND HARDER TO STOP. NOW EVEN THE PASSENGERS HEAR AND FEEL THE PROBLEM. YET WHEN I CALL TOYOTA TO BRING THE CAR IN THEY SAY THERE IS NO RECALL. *TR

I EXPERIENCE A FEW TIMES WEEK SINCE LAST SUMMER WHEN I GOT MY 2010 PRIUS THE "1 SECOND" BRAKE FAILURE THAT HAS BEEN REPORTED FOR 2010 PRIUS VEHICLES. AS AN OWNER OF SUCH VEHICLE, THE POTHOLE ON MY USUAL FREEWAY ON RAMP AND THE SPEED BUMP IN MY WORK'S PARKING GARAGE BOTH CAUSE A QUICK ACCELERATION FEELING FOR ABOUT 1/2 SECOND IF I'M APPLYING THE BRAKES AT THE MOMENT OF PASSING OVER THE POTHOLE OR SPEED BUMP. THAT 'FEELING' MAY BE NOT AN ACCELERATION BUT A MOMENTARY BRAKE FAILURE. THE FAILURE IS ONLY ABOUT 1/2 SECOND AND I'M USED TO IT NOW, THOUGH OBVIOUSLY IT IS AN UNSAFE SITUATION. IF I COME ACROSS SUCH EVENTS WHILE, SAY, BRAKING HARD WHEN I SEE A PEDESTRIAN IN THE PARKING LOT, I COULD FAIL TO AVOID HITTING THE PERSON. *TR

THE CRUISE CONTROL ON MY 2010 TOYOTA PRIUS DOES NOT ALWAYS CANCEL WHILE BRAKING. THIS HAS RESULTED IN UNINTENDED ACCELERATION AFTER BRAKING WHILE THE CRUISE CONTROL HAS BEEN SET. A DRIVER EXPECTS THAT THE CRUISE CONTROL WILL AUTOMATICALLY CANCEL WHILE APPLYING THE BRAKES BUT THIS DOES NOT HAPPEN UNDER LIGHT BRAKING. THIS IS EVEN MORE PRONOUNCED WHILE DRIVING UP A STEEP HILL. ON JANUARY 11TH, 2010, I WAS IN A SITUATION WHERE I ACTUALLY APPLIED THE BRAKES TO REDUCE MY SPEED WHILE TRAVELING UP A STEEP HILL AND FELT THE CAR "FIGHTING" AGAINST ME TO MAINTAIN A STEADY SPEED. AFTER I HAD SLOWED MY PRIUS TO MATCH THE SPEED OF THE CAR IN FRONT OF ME, THE CRUISE CONTROL UNEXPECTEDLY CAUSED THE CAR TO ACCELERATE AGAIN, PLACING ME AT A LESS THAN SAFE DISTANCE TO THE CAR IN FRONT OF ME AS WE CRESTED THE HILL. *TR

MY HUSBAND AND I BOUGHT A 2010 TOYOTA PRIUS IN NOVEMBER 2009. WE BOTH HAVE NOTICED A SORT OF JERKY FEELING WHILE BRAKING OVER A SMALL BUMP OR POTHOLE BUT WE DIDN'T THINK MUCH OF IT UNTIL LAST NIGHT WHEN I WAS DRIVING HOME WITH MY CHILDREN. I WAS DRIVING DOWN A RESIDENTIAL AREA AT ABOUT 30 MILES/HR. AND WAS SLOWING DOWN TO STOP AT A RED LIGHT. WHILE I WAS BRAKING I HIT A MEDIUM SIZED POT HOLE. MY CAR JUST LEAPT FORWARD ABOUT 10 FEET. I HAD MY FOOT ON THE BRAKE FIRMLY THE ENTIRE TIME BUT THE CAR WOULD NOT STOP. FINALLY MY CAR CAME TO A STOP. I WAS VERY SHAKEN BY THIS INCIDENT. IF THERE WAS A CAR IN FRONT OF ME I WOULD HAVE TOTALLY REARENDED THEM. I CAME HOME AND IMMEDIATELY CALLED THE TOYOTA DEALERSHIP. I LEFT A MESSAGE WITH THE SERVICE DEPARTMENT. MY CALL WAS RETURNED BY THE MANAGER THIS MORNING. SHE SAID THAT SHE HAD NOT HEARD ANYTHING FROM TOYOTA ABOUT ANY BRAKE ISSUES AND THEN SHE ASKED ME WHETHER I WAS SPEEDING! SHE DID NOT SEEM TO BELIEVE ME AND BASICALLY SAID THAT THERE WAS NOTHING THAT THEY COULD DO.*TR

THE VEHICLE IS A VERY NEW PRIUS VERSION 3. THERE IS NO PROBLEM WITH THE FLOOR PADS. THERE DOES NOT SEEM TO BE A PROBLEM AT HIGHER SPEEDS. THE PROBLEM IS SHORT, UNEXPECTED BURSTS OF ACCELERATION AT LOWER SPEEDS, ESPECIALLY AS THE CAR IS SLOWING DOWN, WITH OR WITHOUT BRAKING. I BELIEVE IT OCCURS ESPECIALLY WHEN THE ENGINE SHIFTS FROM HYBRID TO ALL ELECTRIC. FOR EXAMPLE, ON A CURVING EXIT RAMP OFF A ROAD, AS THE CAR SLOWS, AND AS BRAKING AND ACCELERATION ARE RELEASED, AND THE CAR SHIFTS INTO PROPELLING ITSELF ON ELECTRIC, THERE IS A BURST OF ACCELERATION AT SOME TIME IN THIS MANEUVER. THIS HAS HAPPENED SEVERAL TIMES SINCE PURCHASING THE CAR A FEW WEEKS AGO. I SPOKE TO THE SERVICE MANAGER AT HE DEALERSHIP LAST WEEK. HE STATED HE KNEW NOTHING ABOUT THIS, AND HAD HEARD NORTHING FROM TOYOTA. HE OFFERED TO LOOK AT THE CAR IF I BROUGHT IT IN. SUBSEQUENTLY THE PRIUS PROBLEM BECAME NEWS.*TR

I OWN A 2010 PRIUS PURCHASED AROUND SEPT. 2009. A FEW WEEKS AFTER WE GOT THE VEHICLE, MY WIFE AND I INDEPENDENTLY BOTH EXPERIENCED A SUDDEN ACCELERATION WHEN THE CAR WENT OVER A BUMP. THIS HAS OCCURRED ABOUT A TOTAL OF 4 TIMES. MY FOOT WAS NOT ON THE ACCELERATOR AT THE TIME THIS OCCURRED. STEPPING ON THE BRAKE DID SLOW THE VEHICLE DOWN. THE LAST TIME I EXPERIENCED THIS WAS 2-3 WEEKS AGO. I DID ASK THE DEALER SHORTLY AFTER THE INITIAL INCIDENT IF HE HAD HEARD OF THIS PROBLEM AND HE SAID NO. I HAVE NOT SINCE BROUGHT THE CAR BACK TO THE DEALER. WE HAVE NOTICED THIS ONLY WHEN THE CAR GOES OVER A BUMP.*TR

WHILE DRIVING MY WIFE'S 2010 TOYOTA PRIUS FROM COLORADO SPRINGS TO ALAMOSA WE EXPERIENCED THE FOLLOWING ANOMALY. WE WERE ON THE FREEWAY (I-25) DRIVING SOUTH ON LEVEL TERRAIN WITH THE CRUISE CONTROL SET AT ~70MPH. I NOTICED A SIGNIFICANT INCREASE IN THE ENGINE RPM AND COULD SEE THE ENGINE DISPLAY FOR THE ENGINE IN THE PWR MODE. I DISENGAGED THE CRUISE CONTROL AND WAITED A SHORT PERIOD OF TIME AND REENGAGED THE CRUISE CONTROL. A SHORT TIME LATER (~15 MINUTES) THE RPM INCREASE OCCURRED AGAIN AND I ONCE AGAIN DISENGAGED THE CRUISE CONTROL. I DID NOT USE THE CRUISE CONTROL AGAIN ON THE TRIP. MY WIFE HAS USED THE CRUISE CONTROL RARELY SINCE HER USE DOES NOT INCLUDE FREEWAY DRIVING. *TR

I OWN A 2010 PRIUS AND TOOK THE CAR INTO THE LOCAL TOYOTA DEALER 2 DAYS AGO FOR THE INITIAL 5,000 MILE CHECK UP TO DISCUSS A COUPLE ISSUES I HAVE FOUND WITH THE CAR. I HAVE EXPERIENCED ON 3 OCCASIONS A FEELING OF BRAKE FAILURE. THIS HAS OCCURRED WHEN I AM DRIVING OVER ROUGH ROAD. WHILE THE BRAKE IS BEING APPLIED IF I HIT BUMPS, THE BRAKE PEDAL DROPS AND I LOSE THE BRAKES. I HAVE IMMEDIATELY LET UP ON THE BRAKE AND THEN REAPPLIED PRESSURE TO THE BRAKE PEDAL TO GET BRAKING BACK. THE DEALER TRIED TO ACHIEVE THE SAME PROBLEM BUT WAS UNABLE TO REPLICATE IT. HE SAID IT WAS JUST THE WAY THE PEDAL MUST FEEL TO ME. OUR DAUGHTERS BOTH HAVE 2006 PRIUS' WHICH I HAVE DRIVEN AND NEVER EXPERIENCED THIS PROBLEM WITH THEIR CAR BRAKES. THE SECOND PROBLEM IS WITH CRUISE CONTROL. AGAIN, I HAVE DRIVEN A 2006 PRIUS AND USED CRUISE CONTROL AND NOT EXPERIENCED THE FOLLOWING IN THE 06 MODEL THAT OCCURS IN OUR 2010 MODEL. THE CAR STARTED TO ACCELERATE IN CRUISE MODE. WE HAVE ALSO FOUND IT TAKES A LOT OF PRESSURE ON THE BRAKE PEDAL TO TAKE IT OUT OF CRUISE CONTROL. THE CAR JERKS WHEN TAPPING THE BRAKE PEDAL LIGHTLY TO TAKE OFF CRUISE CONTROL. THE DEALER AGAIN TOOK IT OUT FOR A TEST DRIVE AND SAID THIS IS THE WAY THE PRIUS FEELS. I KNOW DRIVING THE 2006 MODEL IT WAS NOT THE WAY THE PRIUS FEELS WHEN YOU TAKE IT OUT OF CRUISE CONTROL. *TR

WHEN SLOWING DOWN OVER BUMPY SURFACES, THE CAR TEMPORARILY LOSES BRAKING CONTROL (FOR A SECOND OR SO). IT IS TERRIFYING AND NEEDS TO BE LOOKED INTO. THERE ARE HUNDREDS OF PEOPLE ONLINE WHO HAVE REPORTED THIS EXACT SAME PROBLEM. *TR

I OWN A 2010 TOYOTA PRIUS..PURCHASED IN AUGUST 2009...CURRENTLY GOING FOR 15K MILES ON THE ODOMETER. I WANT TO REPORT ISSUES WITH SUDDEN ACCELERATION EVEN WHEN I AM STEPPING ON THE BRAKE. I NOTICED EVERY TIME I PASS THRU UNEVEN ROAD, FOR EXAMPLE POTHOLES, ICY ROADS, SNOW. THE MOST COMMON ISSUE I HAVE IS AS I AM GOING DOWN THE ROAD AND CAR HITS A POTHOLE OR MANHOLE (THOSE WITH METAL COVERS) THE CAR WILL SUDDENLY ACCELERATE, ALTHOUGH I AM STEPPING ON THE BRAKE. SOMETIMES I AM AFRAID I WILL HIT THE CAR IN FRONT OF ME, ESPECIALLY WHEN IM IN TRAFFIC. EVEN GOING AT 5-15 MPH, THE CAR WILL ACCELERATE WHEN IT HITS UNEVEN ROAD LIKE POT HOLES OR ICY ROADS. THIS HAS HAPPEN QUITE A FEW TIMES SINCE I PURCHASED THE VEHICLE. JUST YESTERDAY, WE HAD ABOUT 1-2 INCHES OF SNOW. I WAS DRIVING SLOW AND WHEN MAKING A LEFT TURN, THE CAR HIT SOME UNEVEN ROAD AND SNOW AND ACCELERATED WHEN I WAS STEPPING ON THE BRAKE TO MAKE THE TURN. THE CAR WENT UP THE SIDEWALK AND THE BUMPER CRACKED AS IT HIT THE CONCRETE EDGE THAT SEPARATES THE ROAD AND THE SIDEWALK. NO ONE WAS HURT AND NO PROPERTY DAMAGE WAS DONE. THE CAR IS WORKING FINE, BUT THIS SUDDEN ACCELERATION ISSUE IS A MAJOR CONCERN, ESPECIALLY NOW THAT I READ AND HEAR IN THE NEWS THAT 2010 TOYOTA PRIUS ARE BEING REPORTED WITH COMPLAINTS OF SUDDEN ACCELERATION. I THOUGHT MY ISSUE WAS AN ISOLATED CASE. PLEASE TAKE THIS COMPLAINT INTO ACCOUNT. I WILL BE GOING TO THE DEALERSHIP THIS WEEKEND FOR THE 15K SCHEDULED MAINTENANCE AND WILL REPORT THE ISSUE TO THEM. *TR

Mileage: 6,500

BRAKING WHILE DRIVING OVER A POTHOLE CAUSES THE 2010 PRIUS TO MOMENTARILY FEEL LIKE IT'S ACCELERATING RATHER THAN BRAKING. THIS HAS RESULTED IN NEAR-ACCIDENTS A COUPLE OF TIMES.

I PURCHASED A NEW 2010 TOYOTA PRIUS IN SEPTEMBER 2009 FROM DARCARS TOYOTA IN FREDERICK MD. I HAVE EXPERIENCED (2) INSTANCES OF UNINTENDED ACCELERATION DURING THE TIME SINCE I PURCHASED THE VEHICLE. I HAVE INFORMED DARCARS TOYOTA AND TOYOTA CORPORATION. DARCARS RAN A "HEALTH TEST" ON FEBRUARY 4, 2009 ON MY VEHICLE AND THE TEST INDICATED EVERYTHING ON THE VEHICLE WAS OPERATING NORMALLY. DARCARS THEN CONTACTED THEIR TOYOTA CALIFORNIA (TAC) AND RELATED MY PROBLEM TO THEM. THE RESPONSE FROM TOYOTA WAS THAT MY EPISODES OF UNINTENDED ACCELERATION WAS JUST THE ABS SYSTEM ENGAGING NORMALLY. THIS IS AFTER THE PRESS RELEASE FROM TOYOTA CORPORATION ON THE MORNING OF 02/04/10 ACKNOWLEDGING A PROBLEM EXISTING WITH THE 2010 PRIUS BUT CLAIMING TO HAVE ALREADY FIXED THE PROBLEM ON ALL NEW 2010 PRIUS AUTOMOBILES SOLD SINCE JANUARY 2010. MY TWO QUESTIONS ARE 1) IF TOYOTA DISCOVERED A PROBLEM WITH THE 2010 PRIUS THAT THEY SUPPOSEDLY REPAIRED ON ALL 2010 PRIUS VEHICLES SOLD SINCE JANUARY, WHY HAS TOYOTA NOT CONTACTED ME ABOUT WHAT IS AN OBVIOUS SAFETY ISSUE? I HAVE OWNED AND BEEN DRIVING MY 2010 PRIUS SINCE SEPTEMBER '09. 2) WHAT IS THE SPECIFIC REPAIR THAT WAS SUPPOSEDLY PERFORMED ON ALL 2010 PRIUS AUTOMOBILES SINCE JANUARY 1, 2010? WHY DID MY TOYOTA SERVICE MANAGER HAVE NO KNOWLEDGE OF SUCH A REPAIR? WAS THERE A SAFETY BULLETIN ISSUED BY TOYOTA? WHY HAS TOYOTA NOT ALREADY AGREED TO REPAIR MY 2010 PRIUS (SOLD IN SEPTEMBER '09) WITH THE SAME REPAIR ALLEGEDLY ALREADY PERFORMED ON 2010 PRIUS AUTOMOBILES SOLD AFTER JANUARY 1, 2010? *TR

I HAVE A 2010 PRIUS. ON AT LEAST THREE OCCASIONS, IN THE LAST SIX MONTHS, THE FOLLOWING HAS OCCURRED. WHEN I AM TRAVELING AND I APPLY BRAKE PRESSURE THE VEHICLE BEGINS TO ACCELERATE. NO MATTER HOW HARD I PRESS ON THE BRAKE PEDAL IT DOES NOT SLOW DOWN OR STOP THE VEHICLE. IT ACTUALLY BEGINS TO SPEEDS UP WHILE MY FOOT IS PRESSING DOWN ON THE BRAKE PEDAL. THE ACCELERATION HAS ONLY LASTED APPROXIMATELY 5-6 SECONDS. HOWEVER, IT IS VERY FRIGHTENING WHEN YOU ARE TRAVELING AT A HIGH RATE OF SPEED AND TRYING TO SLOW DOWN ESPECIALLY OFF A FREEWAY OFF RAMP. THE LAST THING YOU WANT TO DO AT THAT TIME IS ACCELERATE EVEN IF IT IS MOMENTARILY. THIS HAS OCCURRED IN VARIOUS PLACES. IT HAS HAPPENED WHILE I AM GETTING OFF OF THE FREEWAY AND ON CITY STREETS.

STARTLED, I IMMEDIATELY PRESSED ON THE FOOT BRAKE, RELEASING IT IN LITTLE STEPS UNTIL THE CAR WAS "INCHED" OUT OF THE PARKING PLACE. I THEN SHIFTED THE LEVER INTO "DRIVE" AND PROCEEDED ON MY WAY QUITE NORMALLY WITHOUT ANY FURTHER PROBLEM WHATSOEVER. IN THE ENSUING MONTHS, THIS STRANGE PHENOMENON HAS ONLY REPEATED ITSELF TWO MORE TIMES OUT OF HUNDREDS OF BACKOUTS FROM PARKING SLOTS. THERE HAS BEEN NO OTHER CIRCUMSTANCE IN WHICH THIS SEVERE " REVVING" HAS RE-OCCURRED. IN THE AFOREMENTIONED THREE CASES, I HAD NO RECOLLECTION WHATSOEVER OF PRESSING THE FOOT THROTTLE, AND THEREFORE HAVE PRESUMED THAT THE PROBLEM IS IN THE ELECTRONICS OR SOFTWARE, RATHER THAN IN THE FLOOR THROTTLE MECHANICS. IN EVERY OTHER RESPECT SO FAR, MY 2010 TOYOTA PRIUS V HAS PERFORMED PERFECTLY. *TR

I HAVE A 2010 TOYOTA PRIUS. SOMETIMES, PARTICULARLY WHEN I'M DRIVING OVER BUMPS, APPLYING THE BRAKE ACTUALLY CAUSES THE VEHICLE TO NUDGE FORWARD INSTEAD OF SLOWING DOWN. ONCE I HAVE CLEARED THE BUMPS, THE BRAKES THEN TAKE EFFECT. THE PROBLEM IS THAT THE CAR MAY NOT ACTUALLY SLOW DOWN FOR AN EXTRA 10 TO 20 FEET. THERE WAS ONE INCIDENT WHERE THIS HAPPENED NEAR A CROSSWALK WHERE PEOPLE WERE CROSSING THE ROAD. THE CAR STOPPED IN TIME, BUT THIS COULD HAVE EASILY TURNED TRAGIC. TOYOTA HAS SAID NOTHING ABOUT THIS AND DON'T THINK THERE IS ANYTHING WRONG WITH THE CAR. *TR

I OWN A 2010 TOYOTA PRIUS. AT LEAST 10 TIMES, WHEN PASSING OVER A BUMP OR POTHOLE IN THE ROAD, THE CAR ACCELERATES WITHOUT MY APPLYING ANY PRESSURE TO THE GAS PEDAL. THAT IS, IT ACCELERATES WITHOUT WARNING SOMETIMES WHEN I PASS OVER A BUMP OR POTHOLE. THEN, WHEN I TRY TO SLOW IT DOWN FROM THIS UNWANTED ACCELERATION, THE BRAKES DO NOT SEEM TO FUNCTION PROPERLY. THAT IS, THE BRAKES DO NOT SEEM TO PROPERLY AND INSTANTLY "CATCH" TO SLOW THE CAR. RATHER, THERE IS A PULSATING SENSATION FOR AN ESTIMATED 2-5 SECONDS UNTIL THE BRAKES FINALLY AND COMPLETELY "CATCH" TO SLOW THE CAR FROM THE UNWANTED AND UNINTENDED ACCELERATION. I NOTICED THIS SHORTLY AFTER BUYING THE CAR ON AUGUST 11, 2009. FURTHER, I HAVE NEVER EXPERIENCED THIS PHENOMENON WITH ANY OTHER AUTOMOBILE THAT I HAVE DRIVEN IN THE LAST 30 YEARS. IT IS NOT SOME PHENOMENON OR PROBLEM THAT HAS DEVELOPED OVER TIME. RATHER, IT WAS A PHENOMENON THAT OCCURRED WHEN THE CAR WAS ALMOST COMPLETELY NEW WITH FAR LESS THAN 1,000 MILES ON THE ODOMETER. I AM MAKING THIS COMPLAINT AFTER READING IN AN INTERNET NEWS ARTICLE THAT OTHERS ARE EXPERIENCING SIMILAR PROBLEMS WITH THE 2010 TOYOTA PRIUS AS WELL AS THE OTHER RECALLED TOYOTA AUTOMOBILES. I BELIEVE THIS IS A POTENTIALLY DANGEROUS PROBLEM, AND SWIFT U.S. GOVERNMENT ACTION IS BOTH WARRANTED AND NEEDED FOR PUBLIC SAFETY. *TR

2010 TOYOTA PRIUS- CAR TENDS TO ACCELERATE AFTER HITTING SOME POTHOLES OR BUMPS IN THE ROAD WHEN THE BRAKE IS DEPRESSED. THE FIRST COUPLE OF TIMES, I CAME VERY CLOSE TO REAR-ENDING THE CAR IN FRONT OF ME BECAUSE THE BUMP OR POTHOLE WAS IN THE ROAD AT A TRAFFIC LIGHT AND I WAS ATTEMPTING TO STOP. I HAVE BEEN ABLE TO REPEAT INCIDENT BUT NOT ALL OF THE TIME (MAY DEPEND ON HOW HARD THE BRAKE IS DEPRESSED OR HOW FAST THE CAR IS GOING AT THE TIME). I NOTICED THIS SHORTLY AFTER PURCHASING AND RECEIVING THE CAR ON 24 OCT. 2009. MENTIONED TO TOYOTA SERVICE STAFF AT A NEW CAR ORIENTATION PROGRAM, BUT WAS TOLD THAT THEY HAD NOT HEARD OF THIS ISSUE... AND PERHAPS THE BUMPS IN THE ROAD WERE CAUSING ME TO NOT APPLY EVEN PRESSURE ON THE BRAKE. I HAVE ADJUSTED MY DRIVING ROUTE AS TO NOT TO GO OVER THE POTHOLE WHICH CAUSES THE MOST PROBLEMS (OR TRY TO BE VIGILANT ABOUT SITUATIONS WHICH MAY CAUSE LURCHING) BUT WAS CONCERNED WHEN I SAW AN ARTICLE REPORTING THAT OTHER PEOPLE ARE EXPERIENCING SIMILAR ISSUES (HTTP://WWW.FREEP.COM/ARTICLE/20100203/BUSINESS01/100203028/1318/2010-PRIUS-OWNERS-COMPLAIN-OF-FAULTY-BRAKES-LURCHING-OVER-BUMPS). *TR

THIS HAPPENS SPECIFICALLY IF A POTHOLE OR BUMP IN THE ROAD IS HIT AND I'M BRAKING. MOSTLY WHEN SLOWING DOWN BY HITTING THE BRAKE. I ACTUALLY NOTICED THIS ALMOST IMMEDIATELY WHEN I BOUGH THE CAR BUT SINCE I'VE BEEN READING UP A LOT ABOUT THE 2010 PRIUS NOT IN THE TOYOTA RECALL LIST, I THOUGHT IT IS IMPORTANT TO REPORT IT AND GET IT FIXED. ONE EXPERIENCED THE STRANGEST FEELING WHEN THIS HAPPENS. ALMOST AS IF THE BREAK PEDAL IS HIT AND THE CAR JERKS FORWARD AS IF THE PEDAL IS STUCK AND THE CAR BODY MOVES FORWARD. *TR

SUDDEN SURGE WHEN HITTING A BUMP AT MEDIUM SPEEDS. MY PRIUS IS NOW SIX MONTHS OLD WITH ABOUT 6,000 MILES ON IT AND I EXPERIENCE A SURGE IN ACCELERATION WHEN I HIT A BUMP AT ABOUT 20 MPH. I USED TO BE AN AUTO MECHANIC (20 YEARS AGO), SO I MAY BE A LITTLE MORE ATTUNED TO NARROWING THE PROBLEM THAN MOST PEOPLE. I HAVE NOTICED THAT WHEN THIS SURGE HAPPENS I AM LIGHTLY ON THE BRAKES (TOTALLY OFF THE ACCELERATOR). THIS SEEMS TO PARTICULARLY HAPPEN WHEN THE BUMP (LIKE A POTHOLE IN THE ROAD) IS UNDER THE RIGHT FRONT WHEEL. EVEN MORE FRUSTRATING IS THAT THIS DOES NOT HAPPEN EVERY TIME NOR ON EVERY BUMP. I CAN TELL YOU THE FLOOR MAT HAS NOTHING TO DO WITH IT AND I DO NOT THINK THE OUTSIDE TEMPERATURE HAS ANYTHING TO DO WITH IT EITHER. MY SHADETREEMECHANIC'S DIAGNOSIS IS THAT THIS IS A SOFTWARE GLITCH THAT GETS ACTIVATED WHEN THE BRAKING SOLENOID IS BUMPED. *TR

I OWN A 2010 PRIUS, AND HAVE EXPERIENCED AN ACCELERATION ISSUE ON ABOUT 3-4 OCCASIONS SINCE PURCHASING THE VEHICLE IN AUGUST OF 2009. THE ISSUE I HAD WAS PERFECTLY DESCRIBED IN A RECENT ON-LINE ARTICLE FROM MONEY.CNN.COM ON FEB 3. HERE IS THE QUOTE - "THE COMPLAINTS RECEIVED VIA OUR DEALERS CENTER AROUND WHEN DRIVERS ARE ON A BUMPY ROAD OR FROZEN SURFACE," A TOYOTA MOTOR CORP. SPOKESMAN IN JAPAN, SAID. "THE DRIVER STEPS ON THE BRAKE AND THEY DO NOT GET AS FULL OF A BRAKING FEEL AS EXPECTED." THIS IS EXACTLY WHAT I'VE EXPERIENCED, AND IT ALSO SEEMS TO POSSIBLY BE RELATED TO THE SHIFT FROM GAS TO ELECTRIC WHICH OCCURS WHEN SLOWING DOWN. AFTER BRAKING, THERE IS A SUDDEN, BRIEF SURGE OF ACCELERATION. I HAVE NOT BROUGHT THIS INTO THE DEALER, BUT PLAN TO SOON. *TR

I PURCHASED MY 2010 TOYOTA PRIUS IN DECEMBER 2010. TWICE IN THE LAST TWO WEEKS MY CAR HAS UNEXPECTEDLY LURCHED FORWARD AS I WENT OVER A SPEED BUMP AT A RELATIVELY LOW SPEED. SINCE IT WAS THE SAME SPEED BUMP BOTH TIMES, I REASON THAT IT MUST HAVE SOMETHING TO DO WITH THE HEIGHT OF THE BUMP AND/OR MY ANGLE OF APPROACH. I WAS ABLE TO REGAIN CONTROL OF THE VEHICLE BOTH TIMES. I AM REPORTING THIS BECAUSE I HAVE READ THE NEWS ARTICLES ABOUT OTHERS HAVING SIMILAR PROBLEMS WITH 2010 PRIUS' AND THOUGHT THAT YOU WOULD WANT TO KNOW.

THEY SAID THEY HAD NO OTHER REPORTS AND COULD NOT REPLICATE IT. THE SERVICE MANAGER TOOK ME ON A TEST DRIVE AND THE CAR WAS FINE. I KNEW THIS WOULD HAPPEN AS THE ACCELERATION IS ONLY OCCASIONAL.

I HAVE A NEW TOYOTA PRIUS 2010 AND HAVE EXPERIENCED THE LOSS OF BRAKING COMBINED WITH A SIMULTANEOUS ACCELERATION ABOUT 4 TIMES NOW. IT IS INCREDIBLY SCARY. 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 DO NOT HAVE THE WIN NUMBER ON HAND, BUT WILL ADD IT TOMORROW. THIS HAS OCCURRED APPROX 4 TIMES AND THE CAR ACCELERATES AT THE SAME TIME I LOSE BRAKING CAPABILITIES. *TR

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

I HAVE A 2010 PRIUS WHICH I BOUGHT IN AUGUST 2009. ON SEVERAL OCCASIONS, APPROXIMATELY 8-10 TIMES, I HAVE BEEN BRAKING AT SLOWER SPEEDS WHEN COMING TO AN INTERSECTION. WHEN I PUT MY FOOT ON THE BRAKE AND THE CAR HAPPENS TO HIT A BUMP OR HOLE IN THE ROAD AND THE CAR NOTICEABLY SURGES. MY FOOT IS NOT ON THE ACCELERATOR AND THIS HAS NOTHING TO DO WITH THE FLOOR MATS BECAUSE MY FLOOR MAT IS PINNED TO THE FLOOR OF THE CAR. THE MOST RECENT TIME THIS HAPPENED WAS 12/28/2009. *TR

IN REVERSE CAR SPEEDS AND BRAKE STIFFENS AND UNABLE TO SLOW REVERSE SPEED. ALSO, TWO TIMES WHILE ACCELERATING AT 25 MILES PER HOUR THE CAR SEEMED TO LIFT UP THEN SETTLE DOWN. VERY FRIGHTENING. *TR UPDATED 02/02/10 *BF THE CONSUMER STATED WHEN THE VEHICLE WAS IN REVERSE, THE BRAKES FROZE. THE DAY AFTER THE VEHICLE WAS AT THE DEALER, THE CONSUMER PARKED ON A SMALL INCLINE, THE FRONT FACING UP. WHEN SHE STARTED THE VEHICLE, SHE PUSHED THE START BUTTON, PUT THE VEHICLE IN REVERSE, DISENGAGED THE EMERGENCY BRAKE, AND IMMEDIATELY THE BRAKES FROZE AND THE CONSUMER STARTED TO GO BACKWARDS WITHOUT CONTROL OF THE BACKING UP THE CAR. THE CONSUMER WAS UNABLE TO CONTROL THE BACKWARDS MOVEMENT SO SHE IMMEDIATELY SHUT DOWN THE POWER. SHE THEN STARTED THE VEHICLE AGAIN, PUT IT REVERSE, DISENGAGED THE EMERGENCY BRAKE AND EVERYTHING WAS NORMAL. UPDATED 03/01/10 UPDATED 05/05/10.*JB

TOYOTA PRIUS 2010: WHEN THE CAR HITS A BUMP IN THE ROAD IT WILL ACCELERATE SO FAST BY ITSELF WHICH CAN BE VERY DANGEROUS AND FATAL. IT CAN HIGHLY CAUSE AN ACCIDENT IF THE DRIVER CANNOT STEP ON THE BRAKES IN TIME TO STOP THE CAR ACCELERATION. I WENT TO MY LOCAL TOYOTA DEALER HERE IN QUEENS NEW YORK AND TO MY SURPRISE THE REP SAID" I HAVE NEVER HEARD OF THAT COMPLAINT" AND DID NOT PURSUE THE MATTER AT ALL. ANOTHER SAFETY CONCERN IS THAT I HIT A SMALL POTHOLE AND THE WHOLE TIRE WAS DAMAGED ON MY BRAND NEW 2010 PRIUS WHICH I HAVE BEEN DRIVING FOR BARELY TWO MONTHS. I AM VERY CONCERNED ABOUT THESE SAFETY PROBLEMS AND DO NOT REALLY KNOW WHERE TO START GETTING ASSISTANCE. THANK YOU VERY MUCH. *TR

I WAS DRIVING MY NEW 2010 PRIUS (APPROX. 250 MILES ON ODOMETER) WHEN APPROACHING A STOP LIGHT EARLIER TODAY WITH MY FOOT GENTLY APPLYING PRESSURE TO THE BRAKE WHEN SUDDENLY THE CAR SURGED FORWARD ACCELERATING. I AM CERTAIN MY FOOT WAS NOT ON THE ACCELERATOR PEDAL NOR WAS ANYTHING ON THE FLOOR AND THE FLOORMAT WAS APPROPRIATELY POSITIONED. THE ACCELERATION ONLY LASTED A SECOND, IE ONCE I APPLIED MORE PRESSURE SHARPLY TO THE BRAKE PEDAL THE CAR SLOWED AND THE ACCELERATION CEASED. THIS IS THE ONLY TIME THIS HAS OCCURRED. *TR

I BOUGHT A 2010 PRIUS IN SEPTEMBER 2009. IN OCTOBER, I DROVE OVER A POTHOLE THAT WAS ABOUT 6 INCHES DEEP AND COVERED THE ENTIRE WIDTH OF THE LANE. HERE IS WHAT IT FELT LIKE HAPPENED: WHEN THE BACK WHEELS HIT THE BOTTOM OR THE TOP OF THE POTHOLE, MY CAR SUDDENLY ACCELERATED AND I HAD A VERY DIFFICULT TIME STOPPING IT. I MANAGED TO NOT CRASH INTO THE CAR IN FRONT OF ME, BUT JUST BARELY. IT HASN'T HAPPENED SINCE. THE POTHOLE WAS APPARENTLY THE RESULT OF WORK ON THE ROAD, B/C IT WAS SQUARED, LIKE THE PAVEMENT HAD BE INTENTIONALLY CUT. *TR

2010 TOYOTA PRIUS ACCELERATES SLIGHTLY WHEN BRAKE IS COMPRESSED AND CAR IS TRAVELING OVER LARGE ROAD BUMPS OR MANHOLE COVERS/SLIPPERY SURFACES (MULTIPLE TIMES EACH TIME I DRIVE). I HAVE NOT YET REPORTED THIS TO TOYOTA, BASED ON THE ONLINE AND NEWS-BROADCAST ACCOUNTS OF HOW TOYOTA HAS RESPONDED TO MUCH MORE SERIOUS ACCELERATION ISSUES. I INTEND TO ATTEMPT RETURNING THE VEHICLE TO THE COMPANY FOR A FULL REFUND. *TR

I HAVE A 2010 TOYOTA PRIUS AND IT ACCELERATES RANDOMLY. USUALLY WHEN I PUSH ON THE BRAKE A LITTLE BIT, BUT NOT ALL THE WAY, IT WILL JUMP FORWARD AND ACCELERATE. I HEARD ABOUT THE ISSUES WITH THE MAT AND I REMOVED THE MAT MONTHS AGO. ITS IS STILL UNINTENTIONALLY ACCELERATING. IT HAS HAPPENED MAY 6 TIMES SINCE I BOUGHT THE CAR IN JULY. I AM SCARED TO DRIVE IT AND HAVE BEEN DRIVING MY SPARE CAR UNTIL SOMETHING IS DONE BY TOYOTA OR SOMEONE ELSE THAT CARES ABOUT THE SAFETY OF DRIVERS. *TR

WHILE APPLYING THE BRAKES TO SLOW DOWN OR TO COME TO A STOP, IF THE CAR HITS A BUMP, POTHOLE OR THE LIKE, THE BRAKES RELEASE MOMENTARILY, CAUSING THE CAR?S MOMENTUM TO CONTINUE FORWARD LONGER/FURTHER THAN YOU WOULD NORMALLY EXPECT OR WANT. THIS IS ESPECIALLY DANGEROUS WHEN COMING TO A STOP AT A NEW YORK CITY PEDESTRIAN CROSSWALK OR TRYING TO SLOW DOWN WITH A CAR CLOSE IN FRONT OF YOU. I BROUGHT THE CAR INTO THE DEALERSHIP AND HAD IT EVALUATED BY TOYOTA'S FIELD TECHNICAL SPECIALIST WHO REPORTED THE FOLLOWING, ""WHEN [THE CAR] SENSES IMPENDING WHEEL SLIP, IT WILL FIRST DISABLE THE REGENERATIVE BRAKES. WHEN IT DOES THAT IT FEELS LIKE THE CAR SORT OF ACCELERATES BECAUSE YOU LOST THE REGENERATIVE BRAKING AND YOU'RE USING THE BRAKE ASSIST THAT YOU HAVE FROM YOUR FOOT. SO THAT IS 'NORMAL OPERATION' ON THE SYSTEM. IT IS WORKING AS DESIGNED." DESPITE THE EXPLANATIONS FOR WHY THIS IS HAPPENING AND WHETHER OR NOT THIS IS ?NORMAL OPERATION?, THE BOTTOM LINE IS, IF THE CAR IS NOT STOPPING WHEN IT SHOULD, THE SAFETY OF PASSENGERS AND PEDESTRIANS IS IN JEOPARDY. I CALLED AND WROTE TWO CERTIFIED LETTERS TO TOYOTA'S CUSTOMER EXPERIENCE DEPARTMENT AND TO AKIO TOYOTA, AND RECEIVED A PHONE CALL FROM AN EXECUTIVE ANALYST FROM THE PRESIDENT'S OFFICE. NO TOYOTA REPRESENTATIVE WOULD DO ANYTHING IN REGARDS TO THE PROBLEM--THEY MAINTAIN THAT THE BRAKING OPERATION IS NORMAL. I HAVE SEEN OTHER COMPLAINTS ON THE NHTSA WEB SITE AND ON PRIUS OWNERS BLOGS THAT CONTRADICT TOYOTA'S ASSERTION AND SUPPORT THE CLAIM THAT THE BRAKES ARE INDEED A SAFETY ISSUE THAT MUST BE ADDRESSED.*TR

RE: 2010 PRIUS. WHEN BRAKING OVER A POTHOLE, THE CAR SURGED FORWARD SUDDENLY (SUDDEN ACCELERATION DESPITE BRAKING). *TR

MY NEW 2010 PRIUS ACCELERATED ON IT'S OWN AS I WAS BRAKING AND SLOWLY APPROACHING THE CAR IN FRONT OF ME THAT WAS STOPPED AT A STOP LIGHT QUITE SOME DISTANCE AWAY. MY CAR HAD ALMOST COME TO A COMPLETE STOP WHEN SUDDENLY THE ENGINE REVVED ON IT'S OWN AS MY FOOT WAS STILL ON THE BRAKE. I HAD TO PRESS DOWN SO HARD ON THE BREAK TO KEEP IT FROM SURGING FORWARD THAT THE ABS LIGHT CAME ON AND THEN THE CAR'S REV WENT DOWN ON IT'S OWN AND ALL WAS BACK TO NORMAL AND HADN'T HAPPENED AGAIN SINCE. I BROUGHT THE CAR TO THE DEALER AND THEY KEPT IT FOR TWO DAYS BUT DIDN'T FIND ANYTHING WRONG WITH IT. I HAVE TWO SMALL CHILDREN AND BOUGHT THIS CAR FOR A NUMBER OF REASONS, SAFETY BEING ONE OF THE IMPORTANT ONES. I AM NO LONGER FEELING SAFE. THIS WAS NOT THE FLOOR MATS, OR A SUDDEN STOP MISTAKING ONE PEDAL FOR ANOTHER, OR ANY OTHER FORM OF DRIVER ERROR. THIS WAS THE CAR! PLEASE HELP TO DISCOVER THE CAUSE AND MAKE TOYOTA FIX IT BEFORE SOMEONE GETS HURT OR KILLED. THANK YOU, CHRIS TOPPIN *TR

ON THREE OCCASIONS, WHILE DRIVING ON CLEAN, DRY ROAD SURFACES, MY 2010 PRIUS SUDDENLY AND BRIEFLY ACCELERATED WITHOUT ANY WARNING AFTER I DROVE OVER MINOR BUMPS AND, ONE 1 OCCASION, A MANHOLE COVER, WHILE BRAKING. THE SENSATION WAS THAT OF THE ENGINE SUDDENLY SURGING AND ACCELERATING. I WAS FORTUNATELY ABLE TO APPLY HARDER PRESSURE TO THE BRAKE PEDAL, REGAINED CONTROL OF THE VEHICLE AND AVOIDED CRASHING INTO THE CAR IN FRONT OF ME. I SPOKE WITH A TOYOTA FIELD TECHNICAL SPECIALIST TODAY WHO TOLD ME THAT THE MECHANICS OF THE CAR ARE SUCH THAT IF A WHEEL HITS A BUMP OR MOVES ONTO A SURFACE THAT CAUSES IT TO ROTATE AT A DIFFERENT RATE VERSUS THE OTHER WHEELS, THE CAR THINKS IT IS GOING INTO A SKID, AND THE ABS SYSTEM KICKS IN. ALSO, THE SYSTEM THAT GENERATES ENERGY TO RECHARGE THE BATTERY, WHICH ALSO EFFECTIVELY BRAKES THE CAR, SUDDENLY CEASES TO OPERATE. CONSEQUENTLY, YOU HAVE THE SENSATION OF ACCELERATION WHEN IN FACT, ACCORDING TO THE TOYOTA SPECIALIST, THE CAR STOPPED DECELERATING. NONETHELESS, THIS SUDDEN DECELERATION IS UNEXPECTED, AND IF I WAS NOT FOCUSED AT THOSE EXACT MOMENTS AND FAILED TO IMMEDIATELY APPLY SIGNIFICANT PRESSURE TO THE BRAKE PEDAL, I COULD HAVE EASILY CRASHED INTO AN OBJECT, OR CAR, OR PERSON, IN FRONT OF ME. I DO NOT FEEL SAFE IN THIS CAR, AND AM WORRIED THAT MY WIFE OR SON COULD HAVE A MAJOR PROBLEM RESPONDING TO THIS SUDDEN LACK OF CONTROL. THERE IS GREAT POTENTIAL FOR SERIOUS INJURY OR DEATH FROM THIS TYPE OF INCIDENT. MY CAR IS ABOUT 1 MONTH OLD, WITH 1,250 MILES ON IT. I UNDERSTAND FROM THE SPECIALIST THAT TOYOTA DEALERSHIPS ON LONG ISLAND HAVE HAD AT LEAST ONE OTHER SIMILAR COMPLAINT. *TR
