2010 Toyota Prius complaints

2010 TOYOTA PRIUS - SOMETIMES WHEN BRAKING THE CAR HAS A POWER SURGE AND YOU START MOVING FASTER. *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 A 2010 PRIUS PURCHASED IN DEC 2009. I HAVE EXPERIENCED THE LURCHING FORWARD WHEN GOING OVER BUMPY ROADS (INCLUDING POTHOLES) WHEN THERE ARE ICY CONDITIONS AND MY FOOT IS ON THE BRAKE. THIS HAS HAPPENED AT LEAST 3 TIMES. *TR

2010 PRIUS II WITH 2070 MILES. PURCHASED 8/2009. WHEN GOING OVER A BUMP WHILE STEPPING ON THE BRAKE THE CAR SEEMS TO ACT AS IF THERE IS NO BRAKE ON THE DOWNSIDE OF THE BUMP. IT FEELS LIKE A SLIGHT ACCELERATION THEN THE BRAKE ENGAGES.. THIS HAS OCCURRED AT LEAST 4 TIMES, BUT DOES NOT HAPPEN IN EVERY INSTANT OF A SIMILAR SITUATION. *TR

THIS IS TO REPORT THAT MY PRIUS 2010 CAR HAS EXPERIENCED THE DELAYED BRAKE PROBLEM. I FIND THIS HAPPENS WHEN I AM DRIVING OVER A CERTAIN ROAD THAT HAS SOME SMALL BUMPS. I AM GOING AROUND 20 OR LESS STOPPING FOR A STOP LIGHT AND I GET A VERY SLIGHT DELAY IN BRAKING, LESS THAN 1 SECOND I THINK. I HAVE NEVER HAD ANY TROUBLE STOPPING IN THE REQUIRED DISTANCE BEFORE THE STOP LIGHT, IT JUST GETS YOUR ATTENTION AND NEEDS CORRECTING BY TOYOTA. *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

I PURCHASED A 2010 TOYOTA PRIUS IN NOVEMBER 2009. ABOUT 10 TIMES SINCE THEN, I'VE FELT THE SENSATION OF 'GOING AIRBORNE' WHEN BRAKING ON A SPEED BUMP OR UNEVEN PAVEMENT. THE SENSATION IS MOMENTARY, AND THE BRAKES HAVE ALWAYS 'RECOVERED'. THERE WAS ONLY ONE TIME WHEN I THOUGHT THAT AN ACCIDENT MIGHT HAPPEN, WHEN I NEEDED TO BRAKE SUDDENLY BEHIND ANOTHER CAR. *TR

I AM THE OWNER OF A 2010 TOYOTA PRIUS, SINCE JULY 2009. I HAVE HAD SEVERAL (APPROX 5) INCIDENCES OF ODD BEHAVIOR WITH MY BRAKES. IT HAS HAPPENED EACH TIME WHEN I GO OVER A BUMPY SURFACE AND APPLY THE BRAKE PEDAL. THE CAR SEEMS TO LUNGE FORWARD FOR AN INSTANT AND THEN MAINTAINS. SEVERAL WEEKS BACK THIS HAPPENED AND WHEN I RESEARCHED THIS ON THE NET I FOUND MANY OTHERS HAD THIS SAME EXPERIENCE. WITH THE RECENT EVENTS, I FELT IT NECESSARY TO MAKE THIS REPORT. *TR

MY 2010 PRIUS STALLED IN TRAFFIC CUTTING OFF ALL POWER INCLUDING EMERGENCY FLASHERS. THE VEHICLE WOULD NOT RESTART FOR 8 MINUTES. I IMMEDIATELY TOOK CAR TO THE DEALER AND REPORTED MY PROBLEM. I WAS TOLD IT WAS A SOFTWARE GLITCH WHICH WAS IMMEDIATELY CORRECTED. *TR

AFTER APPLYING BRAKES AT A BUMPY INTERSECTION THE CAR S BRAKES WERE NON FUNCTIONING AND IT TRAVELED INTO THE INTERSECTION. THIS HAS HAPPENED ON THREE SEPARATE OCCASIONS. *TR

BRAKING ON ROUGH SURFACE RESULTS IN CAR JUMPING FORWARD AND THEN EVENTUALLY STOPPING. *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 APPLYING THE BRAKES ON MY 2010 PRIUS, THERE IS A SURGE IN THE CAR WHEN IT HIT A MANHOLE COVER (BUMP). THIS HAPPENED UNDER 20 MPH ON GENTLE BRAKE APPLICATION. UPON PUSHING ON THE PEDAL FURTHER, THE CAR RESUMED BRAKING AND STOPPED. THIS "SURGE" LASTED ONLY A FRACTION OF A SECOND BUT WAS VERY DISTURBING AND SHOULD NOT OCCUR. *TR

I CURRENTLY OWN A 2010 TOYOTA PRIUS AND OVER THE PAST FEW MONTH I'VE NOTICED A MOMENTARY LOSS IN MY BRAKING WHEN TURNING CORNERS OR COMING TO A STOP. I'M ALITTLE CONCERN THAT THIS MIGHT BE A DEGENERATIVE ISSUE THAT MAY CAUSE A SERIOUS ACCIDENT AT HIGH SPEEDS. *TR

WE PURCHASED A 2010 PRIUS IN AUGUST OF 2009 AND HAVE HAD THE FOLLOWING RECURRING ISSUES: 1. LOSS OF BRAKING WHEN SLOWING DOWN OVER ROUGH OR UNEVEN PAVEMENT, GRAVEL, WET LEAVES, SNOW, ICE, CRACKED PAVEMENT, POT HOLES... THE BRAKES ENGAGE FOR A SECOND, AND THEN WE EXPERIENCE NO BRAKING AT ALL FOR NUMBER OF SECONDS. WE TOOK OUR PRIUS INTO JON LANCASTER TOYOTA IN MADISON, WI WHERE WE PURCHASED THE VEHICLE AND TOLD THE MECHANIC OF THE BRAKING ISSUES WE WERE EXPERIENCING . HE CHECKED OUT THE VEHICLE AND SAID HE COULD NOT FIND ANY ISSUES WITH THE BRAKING SYSTEM AND SAID THAT HE HAD NEVER HEARD OF THIS PROBLEM AND NEITHER HAD TOYOTA. THIS LACK OF BRAKING RESULTED IN A REAR END COLLISION IN DECEMBER 2009. MY HUSBAND WAS DRIVING AT VERY LOW SPEED IN TOWN ONE EVENING AND THIS LACK OF BRAKING ISSUE OCCURRED AND HE SLID INTO ANOTHER VEHICLE. MY HUSBAND PUMPED THE BRAKES FOUR TIMES AND EACH TIME THIS DELAY IN BRAKING OCCURRED. THERE WAS NO BRAKING HAPPENING AT ALL. THE CAR WAS SLOWING DOWN FASTER WHEN THE BRAKES WERE NOT APPLIED, THAN WHEN THE BRAKES WERE APPLIED. THERE WAS FRESH SNOW ON THE ROAD. THERE WAS A DANE COUNTY SHERIFF AT THE INTERSECTION AND MY HUSBAND AND THE PERSON HE HIT RAN THE INCIDENT BY THE STATE PATROL WHO AGREED THAT IT WAS APPROPRIATE FOR THE TWO PARTIES INVOLVED IN THE ACCIDENT TO EXCHANGE INSURANCE AND CONTACT INFORMATION AND LEAVE THE SCENE WITHOUT CALLING THE LOCAL POLICE. THERE WAS DAMAGE TO OUR PRIUS FRONT BUMPER, AND TO THE BACK BUMPER OF THE OTHER VEHICLE. 2. O

I HAVE A 2010 PRIUS PURCHASED IN LATE JULY 2009. I HAVE DEFINITELY HAD PROBLEMS WITH THE BRAKING SYSTEM IN WINTER WEATHER ON SLIPPERY SURFACES. WHEN BRAKING, IT FEELS LIKE THE ANTILOCK BRAKE SYSTEM FAILS AND THE WHEELS LOCK UP MOMENTARILY. I DON'T LET MY WIFE OR KIDS DRIVE THE CAR IN SLIPPERY CONDITIONS. THIS IS DEFINITELY AN ISSUE FOR ME AND I BELIEVE IT SHOULD BE INVESTIGATED AND PURSUED. I HAVE CONTACTED THE DEALER - ALDERMAN'S TOYOTA OF RUTLAND, VT ABOUT THE ISSUE. THEY ARE AWARE OF THE PROBLEM. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY BETWEEN 10 TO 20 MPH ON AN UNEVEN ROAD SURFACE; PROCEEDING TO A COMPLETE STOP AND APPLYING PRESSURE TO THE BRAKE PEDAL, WAS FOLLOWED BY A NO POWER RESPONSE. SUDDENLY, THE VEHICLE RESUMED NORMAL OPERATION WITHIN A FEW SECONDS. THE FAILURE CONTINUED TO OCCUR INTERMITTENTLY WHENEVER ENCOUNTERING AN UNEVEN ROAD SURFACE OR POTHOLE. THE VEHICLE HAS NOT BEEN INSPECTED FOR THE MALFUNCTION. THE FAILURE MILEAGE WAS 300. UPDATED 02/26/10 *BF THE CONSUMER STATED SHE WAS SATISFIED THAT THE COMPLAINT DESCRIBED THE PROBLEM SHE REPORTED. UPDATED 04/29/10.*JB

WE HAVE AN ONGOING PROBLEM WITH OUR 2010 PRIUS, PURCHASED IN 9/09. WHEN GOING OVER A DEPRESSION IN THE ROAD, OR A BUMP, WHEN BRAKES ARE PRESSED, WE FEEL LIKE THE CAR IS BUCKING/ACCELERATING. CLEARLY, IT'S REALLY THAT THE BRAKES AREN'T WORKING MOMENTARILY BUT IT'S FRIGHTENING. IF WE HAD TO STOP, WE COULDN'T. THIS HAPPENS EACH AND EVERY TIME IN THOSE CIRCUMSTANCES. *TR

BOUGHT 2010 TOYOTA PRIUS IN NOV 2009. OVER 20 TIMES SINCE I BOUGHT THE CAR, I HAVE EXPERIENCED SPLIT-SECOND LOSS IN BRAKING POWER WITH MY HYBRID CAR WHEN DRIVING OVER BUMPY OR SLIPPERY ROADS. THIS HAPPENED AGAIN YESTERDAY. ANXIOUSLY AWAIT A RECALL / REPAIR. *TR

I PURCHASED A 2010 TOYOTA PRIUS IN JUNE, 2009. I NOTICED THAT THE VEHICLE SEEMED TO LURCH FORWARD WHEN BRAKING - SPECIFICALLY WHEN THE ROAD MAY HAVE EVEN THE SLIGHTEST BUMP OR UNEVENNESS. WHEN THIS OCCURS, I AM NOT CERTAIN THAT THE CAR WILL STOP. THIS DOES NOT OCCUR DURING BREAKING ON SMOOTH SURFACES. I REPORTED THE PROBLEM TO THE TOYOTA DEALER IN NOV. AND RECEIVED THIS RESPONSE: WEDNESDAY, NOVEMBER 04, 2009 1:05 PM: I'M RESPONDING TO YOUR QUESTION ABOUT THE PRIUS BRAKING CONDITION. ONE THING TO KNOW ABOUT THE PRIUS BRAKING SYSTEM IS THAT WHEN THE BRAKES ARE APPLIED THERE IS A SIGNAL TO THE GENERATOR TO ENGAGE. THIS DOES 2 THINGS, HELPS REGENERATE THE HYBRID BATTERY AND ASSISTS IN BRAKING THE VEHICLE, AND THE NORMAL BRAKES ALSO APPLY TO ASSIST IN BRAKING. I DID HAVE ANOTHER PRIUS OWNER ASK ABOUT THIS ALSO, I HAD HIM COME OUT AND DROVE WITH HIM AND COULD NOT DUPLICATE THE STATED CONDITION. I THINK HE WAS PUSHING TO FAST AND HARD ON THE BRAKE PEDAL CAUSING THE LURCH. WHEN I DROVE HIS VEHICLE I DID TELL HIM I WAS TRYING TO BE VERY CONSCIOUS OF HOW MUCH PRESSURE I WAS APPLYING TO THE PEDAL. I DID NOTICE THE BRAKES ARE VERY RESPONSIVE TO PEDAL PRESSURE. BEFORE RESPONDING TO YOUR E-MAIL I DID CHECK ONLINE WITH TOYOTA TECHNICAL GROUP TO SEE IF THEY HAD ANY PERTAINING SERVICE BULLETINS PERTAINING TO YOUR QUESTION, THERE WERE NO APPLICABLE BULLETINS. I HOPE THIS HELPS ANSWER YOUR QUESTION. THANKS FOR CHOOSING SEEGER TOYOTA, TIM EVERS, SERVICE MANAGER THE PROBLEM HAS CONTINUED AND I'VE

I HAVE BRAKE PROBLEMS WITH MY 2010 PRIUS. NOW THAT I SEE IT'S IN THE NEWS I REALIZE I'M NOT THE ONLY ONE. THE PRIUS HAS ISSUES WHEN I'M BRAKING AND I GO OVER ANY TYPE OF A BUMP IN THE ROAD, OR I GO OVER A POTHOLE COVER. REALLY THERE IS A BRAKING PROBLEM WHEN I AM BRAKING AND THE CAR IS DRIVING OVER DIFFERENT ROAD SURFACES, OR THERE IS BAD WEATHER. THE CAR LURCHES FORWARD- ALMOST FEELS LIKE IT'S SKIPPING A BEAT. IT MAKES MY HEART JUMP, SIMILAR TO A JOLT. I FEEL EVERY TIME THAT I WILL GET INTO AN ACCIDENT, BUT I HAVEN'T YET... THANKFULLY. THIS IS A PROBLEM WITH THE CAR AND NEEDS TO BE ADDRESSED IMMEDIATELY BEFORE SOMEONE DIES, OR GETS SERIOUSLY INJURED. THIS HAPPENS ON AVERAGE ABOUT 1-2 TIMES A WEEK. I DRIVE APPROX 150 MILES A WEEK. *TR

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

WHILE ENGAGING THE BRAKE, BRAKES SEEM TO RELEASE FOR 1 SEC WHILE HOLDING DOWN BRAKE WHILE HITTING BUMP OR WHENEVER TRACTION CONTROL SYSTEM IS ENGAGED. *TR

MOMENTARY LOSS OF BRAKING WHEN ABS ACTIVATES CAUSES CAR TO TRAVEL AN UNEXPECTED 12 FEET. HAS HAPPENED 4 TIMES SINCE DEC 2009. HAPPENS WHEN SLOWING DOWN FOR STOP SIGN, OR MAKING LEFT OR RIGHT TURN IN TRAFFIC, WHEN THERE IS A SLIPPERY PATCH CAUSING ABS TO TRIGGER. *TR

WHILE GOING OVER A SPEED BUMP, MY 2010 TOYOTA SEEMED TO ACCELERATE WHILE THE BRAKE WAS DEPRESSED. THIS HAS OCCURRED ON OTHER OCCASIONS. *TR

2010 TOYOTA PRIUS PURCHASED IN OCTOBER 2009. WHEN BRAKING, CAR HITS A BUMP IN THE ROAD OR ON A ROUGH ROAD, BRAKES APPEAR TO FAIL FOR APPROXIMATELY 2-3 SECONDS. *TR

I OWN A 2010 PRIUS, THAT I PURCHASED SEPTEMBER, 2009. IN DECEMBER I WAS DRIVING IN TOWN, AND CAME TO A STOP. WHEN I CAME TO THE STOP SIGN, I PUT MY BRAKES ON AND HIT A POT HOLE AT THE SAME TIME. IT FELT AS THOUGH THE CAR JERKED FORWARD AND IT WAS A SECOND WHERE I FELT THERE WAS NO BRAKE. *TR

WE OWN A 2010 PRIUS PURCHASED OCT 2009 AND ARE EXPERIENCING THE SAME PROBLEMS DESCRIBED IN THE PRESS FOR THE BRAKE FAILURE PROBLEM CAR JUMPS, OR BRAKES SLIGHTLY UNRESPONSIVE, TEMPORARILY LOSS OF BRAKE POWER. PROBLEM HAPPENS AT SLOW SPEEDS BUT SEEMS INTERMITTENT. NO ACTION HAS BEEN TAKEN, TOYOTA NOT YET CONTACTED. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING APPROXIAMTELY 20 MPH AND MAKING A LEFT OR RIGHT TURN WITH THE BRAKE PEDAL ENGAGED, FOR A FRACTION OF A SECOND. THE ANTI SKID LIGHT ILLUMINATED AND THE BRAKES FAILED TO SLOW THE VEHICLE DOWN. THE VEHICLE WAS TAKEN TO THE DEALER. THE FAILURE MILEAGE WAS 3,000. UPDATED 03/04/10. *LJ UPDATED 05/14/10.*JB

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

I PURCHASED A 2010 TOYOTA PRIUS IN OCTOBER 2009. I HAD TWO INCIDENCES WITH THE BRAKES THAT WERE SIMILAR TO WHAT HAS BEEN REPORTED IN THE PAPERS. THE FIRST WAS WITHIN THE FIRST SIX WEEKS OF OWNING THE CAR. I WAS SLOWING DOWN TO ENTER A GAS STATION AND THE CAR ACCELERATED. I HAD BEEN APPLYING THE BRAKES ALREADY, BUT THE ACCELERATION TOOK ME BY SURPRISE. I APPLIES THE BRAKES MORE FORCEFULLY AND THE CAR SLOWED. THE SECOND TIME I WAS ON MY WAY TO THE DEALER FOR A GET TO KNOW YOU WITH THE MAINTENANCE DEPT. I WAS DESCENDING A HILL WITH THE BRAKES BEING APPLIED. AGAIN THE CAR SPED UP AND I BRAKED MORE FORCEFULLY AND IT SLOWED. IT WAS SCARY. MY HUSBAND SAID THIS HAPPENED ONCE WHEN HE DROVE THE CAR, BUT HE DID NOT REMEMBER THE DETAILS. WHEN WE TOLD THE DEALER, THEY SAID THEY WERE NOT AWARE OF ANY ISSUES WITH THE 2010 PRIUS ACCELERATING OR BRAKING, BUT THAT THEY WOULD LOOK AT THE CAR. OF COURSE, THIS HAPPENED THREE TIMES OVER THREE MONTHS. THEY DIDN'T FIND ANYTHING WRONG WITH THE CAR. SOMEONE ELSE AT THE MEETING SUGGESTING ISSUES WITH THE PROGRAMMING, BUT WE WERE JUST MEETING WITH THE HEAD OF THE REPAIR DEPARTMENT. THEY ONLY KNOW WHAT TOYOTA IS TELLING THEM. NOW I SEE IN THE PAPER THAT TOYOTA CORRECTED THE ISSUE IN THEIR NEW PRIUS. SO THEY KNEW ABOUT THIS AND DIDN'T TELL US. THIS IS THE FIRST AND LAST TIME I WILL BUY A TOYOTA. *TR

MY WIFE EXPERIENCED BRAKING ANOMALIES IMMEDIATELY AFTER BEGINNING TO DRIVE HER NEW 2010 PRIUS. I ATTRIBUTED THESE TO THE WAY THE CAR DRIVES AND I HAVEN'T NOTICED ANYTHING THE FEW TIMES I HAVE DRIVEN IT. BUT THIS IS SOMETHING SHE HAS BEEN REPORTING SINCE SHE FIRST BEGAN DRIVING IT (6 MONTHS) AND SHE IS A PERCEPTIVE PERSON (M.D.). WITH DISCUSSIONS OF WHETHER TO RECALL I FIGURED I SHOULD REPORT THE PROBLEM. *TR

TOYOTA PRIUS 2010 MODEL: BRAKE LAG. I GATHER NHTSA IS CONSIDERING A RECALL. THIS IS TO FURTHER YOUR DATA. I TOOK MY 2010 PRIUS IN TO 355 TOYOTA, ROCKVILLE, IN NOVEMBER TO COMPLAIN ABOUT THE BRAKES DISENGAGING WHEN BEING APPLIED OVER ROUGH TERRAIN, LEADING TO A 4 - 6 FOOT JUMP FORWARD THEN RE-ENGAGEMENT OF THE BRAKES. I LODGED THIS CONCERN AS PART OF GETTING AN OIL CHANGE SERVICE, AND I HAVE THIS COMPLAINT IN WRITING ON THE DOCKET. THEY TOLD ME THE PROBLEM WAS JUST NORMAL ANTILOCK BRAKING. THE PROBLEM HAS OCCURRED MULTIPLE TIMES SINCE, CAUSING ABOUT A 4 - 6 FOOT JUMP BEFORE THE BRAKE REENGAGES. WITH ALL THE ICE WE HAVE HAD RECENTLY, I CAN NOW ASSURE MYSELF THAT THIS ISSUE IS NOT ABOUT THE ANTILOCK BRAKES, WHICH HAVE A TOTALLY DIFFERENT FEEL, AS THEY SHOULD. THE BRAKE DISENGAGEMENT ALMOST CAUSED AN ACCIDENT ON MONDAY THIS WEEK ON E STREET AS THE CAR HIT AN ICE PATCH AND THE BRAKE DISENGAGED MOMENTARILY. I THINK THE PRIUS IS A GREAT CAR, BUT, THIS PROBLEM IS DANGEROUS AND NEEDS TO BE FIXED. WHEN I CALLED 355 TOYOTA YESTERDAY WHEN IT BECAME EVIDENT THAT I WASN'T THE ONLY PERSON REPORTING THIS, THEY WERE VERY NICE BUT I AM NOT SURE THAT TOYOTA HAS PROVIDED THEM WITH A SOLUTION. *TR

WHEN I APPLY THE BRAKES ON THIS VEHICLE ON A BUMPY ROAD THE BRAKES EITHER PAUSE FOR A SECOND TO APPLY OR THE ANTILOCK SYSTEMS SEEMS TO ENGAGE AND DIS-ENGAGE CAUSING A SERIOUS DISTRACTION WHILE BRAKING. THIS OCCURS DAILY AS THE AREA I LIVE IN IS MAINLY BRICK PAVED STREETS. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY 10 MPH OVER A SPEED BUMP OR A POTHOLE WITH HER FEET ON THE BRAKE PEDAL THE VEHICLE LUNGED FORWARD AND ACCELERATED. THE DEALER STATED THAT THE VEHICLE WAS PERFORMING NORMALLY SINCE THE ELECTRICAL ENGINE WAS SWITCHING TO THE GASOLINE ENGINE. THE FAILURE MILEAGE WAS 6,000.

WHEN SLOWING DOWN, IF THE CAR HITS A POTHOLE OR BUMP IN THE ROAD, IT SEEMS TO ACCELERATE. AS SOON AS I PUT PRESSURE ON THE BRAKE, IT STOPS. IT ALMOST FEELS LIKE THE CAR JUMPS AHEAD FOR A BRIEF MOMENT. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY 50 TO 55 MPH ON NORMAL ROAD CONDITIONS PRESSURE WAS APPLIED TO THE BRAKE PEDAL, FOLLOWED BY NO POWER RESPONSE FOR A SECOND. THE FAILURE OCCURRED INTERMITTENTLY. IN ADDITION, WHEN AFTER A COMPLETE STOP THE VEHICLE BEGAN SHAKING EXCESSIVELY. THE AUTHORIZED DEALER AND MANUFACTURER HAVE BEEN NOTIFIED OF THE MALFUNCTIONS. THE FAILURE MILEAGE WAS 400.

WE HAVE THE SAME BRAKING PROBLEM WITH OUR 2010 PRIUS AS DESCRIBED RECENTLY IN NEWSPAPERS. THERE SEEMS TO BE A MOMENTARILY LAPSE OF BRAKING POWER WHEN GOING OVER SLIPPERY OR BUMPY SURFACES. IT HAS HAPPENED NUMEROUS TIMES IN THE PAST FEW MONTHS (WELL OVER 25 TIMES). *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY 35 MPH IN RAINY WEATHER CONDITIONS, THE DRIVER ENCOUNTERED A POTHOLE IN THE ROADWAY AND THE ANTI-LOCK BRAKE SYSTEM ENGAGED. SUDDENLY, THE BRAKE PEDAL TRAVELED TO FLOOR WITHOUT RESISTANCE AND A NO POWER RESPONSE. THE VEHICLE SLOWED DOWN AFTER EXTREME AND CONTINUOUS FORCE WAS APPLIED TO THE BRAKE PEDAL. THE FAILURE OCCURRED WHEN THERE WAS INCLEMENT WEATHER CONDITIONS AND POTHOLES. THE VEHICLE HAS NOT BEEN REPAIRED. THE FAILURE MILEAGE WAS 1,000.

I OWN A 2010 TOYOTA PRIUS. WHILE BRAKING ON A SLICK OR ROUGH PATCH OF ROAD MY CAR WILL BRIEFLY SURGE AND THEN BRAKE. AT FIRST I THOUGHT THIS HAPPENED BECAUSE THE CAR HAS LOW FRICTION TIRES FOR EFFICIENCY. IT HAS HAPPENED ABOUT 5 TIMES SINCE I BOUGHT MY CAR IN AUGUST 2009. AFTER READING THE RECENT REPORTS IT SEEMS LIKE I AM HAVING A BRAKING PROBLEM, NOT A TIRE PROBLEM. *TR

MY CAR (2010 TOYOTA PRIUS) BRIEFLY ACCELERATES WHEN I HIT A SMALL BUMP. IT FEELS LIKE IT IS IN THE ABS SYSTEM. I CALLED MY DEALER SHORTLY AFTER I PURCHASED THE CAR AND THEY SAID THEY HAVE HAD NO COMPLAINTS OF THIS NATURE. I WENT ON A PRIUS CHAT FORUM AND THERE WERE MANY WITH THE SAME COMPLAINT. *TR

I OWN A DRIVING SCHOOL IN LIVINGSTON NJ, I PURCHASED A 2010 PRIUS IN JULY 2009. I ALSO NOTICE A DELAY IN THE BRAKING SYSTEM WHILE DRIVING DOWN A HILL ONE DAY. THIS OCCURRED WHILE I APPLIED THE BRAKES. I WENT OVER A BUMP OR POTHOLE. IT SEEMED LIKE THE CAR ACTUALLY ACCELERATED MOMENTARILY AND I HAD TO KEEP APPLYING THE BRAKES TO THE FLOOR AND HOPED THAT THERE WAS ENOUGH DISTANCE TO STOP. I REMEMBER GOING DOWN A HILL, APPLYING THE BRAKES AND THE CAR WAS SLOWING DOWN, THEN I WENT OVER THE BUMP OR POTHOLE IN THE ROAD AND THE CAR TOOK OFF LIKE I WAS ACCELERATING. I FELT LIKE I HAD LOST CONTROL OF THE VEHICLE FOR AT LEAST 2 SECONDS OR 20FEET BUT FORTUNATELY NO OTHER VEHICLES WERE NEAR BY. I NOW MAKE SURE THAT I BRAKE SOONER, AND ALLOW MORE FOLLOWING DISTANCE. ESPECIALLY IN BAD WEATHER. ANTI-LOCK BRAKES SEEM TO HAVE THEIR OWN UNIQUE PROBLEMS IN THAT THE WHEELS DON'T LOCK BUT THOSE ON THE PRIUS SEEM A BIT MORE NOTICEABLE BECAUSE THEY ARE ELECTRIC AND THE PADS DON'T SLOW THE CAR LIKE NORMAL BRAKES. (AT LEAST THAT WHAT MY SALESMAN TOLD ME.) HE SAID THAT THE PADS WILL LAST OVER 200,000 MILES. HOPEFULLY I'LL BE ABLE TO DRIVE IT THAT LONG WITHOUT AN INCIDENT. BUT THE PROBLEM NOW IIS THAT PARENTS MAY NOT WANT THEIR KIDS TO LEARN WITH MY DRIVING SCHOOL, EVEN THOUGH THERE HAVE BEEN NO REAL PROBLEMS WITH TRAINING TEENAGERS YET. *TR

2010 TOYOTA PRIUS. WHEN FIRST STARTING THE CAR BEFORE THE GASOLINE ENGINE ENGAGES, THE BRAKES GRAB SUDDENLY WHEN APPLIED (E.G. BACKING OUT OF THE GARAGE OR LEAVING A PARKING SPACE), AND CONTINUE TO DO SO UNTIL THE GAS ENGINE STARTS. ALSO, THERE IS MOMENTARY LOSS OF BRAKING WHEN GOING OVER BUMPS (LIKE SPEED BUMPS.) *TR

WHEN INITIALLY STARTING THE CAR (PRIUS 2010) TO BACK OUT OF A PARKING SPOT AND APPLYING THE BRAKES, I HAVE NOTICED A LOSS OF BRAKING (I HAVE PRESSED THE BRAKE PEDAL TO THE FLOOR WITH NO NOTICEABLE BRAKING). WHEN THE BRAKES ARE REAPPLIED, THE BRAKES "GRAB" AND CAUSE SUDDEN, JERKY STOPPING. THIS HAS OCCURRED TWICE. *TR

2010 TOYOTA PRIUS. THERE IS A PROBLEM WITH THE BRAKES WHEN I AM ON A BUMPY ROAD AND WANT TO COME TO A COMPLETE STOP. THE PROBLEM DOESN'T SEEM TO HAPPEN WHEN SLOWING OVER A BUMPY ROAD, ONLY WHEN COMING TO A COMPLETE STOP. THE CAR ALMOST SEEMS TO SKID A BIT AND I DEFINITELY DO NOT FEEL AS IF I HAVE CONTROL OF THE CAR WHEN THIS HAPPENS. WHILE IT'S ONLY A SPLIT SECOND, IT'S NOT A VERY COMFORTABLE SPLIT SECOND. THANKFULLY I HAVE NOT BEEN IN THIS SITUATION WITH ANOTHER CAR IN FRONT OF ME. *TR

WHEN DRIVING, AND GOING OVER A ROUGH SPOT IN THE ROAD (POT HOLE, CRACK, ETC.) THE CAR FEELS LIKE IT IS LURCHING FORWARD MOMENTARILY, AS IF THE BRAKES RELEASED. THIS HAPPENS EVERY TIME THE CAR GOES OVER A ROUGH PATCH IN THE ROAD. *TR

I OWN A 2010 TOYOTA PRIUS. I HAVE HAD MULTIPLE TIMES WHEN I HAVE HIT A BUMP AND WAS APPLYING THE BRAKES AND THE CAR SEEMS TO SKIP OR FLOAT. ON FEB 4, 2010 I WAS APPROACHING A STOP SIGN AND WAS BRAKING. JUST BEFORE THE STOP SIGN I HIT A BUMP AND THE CAR SLID THROUGH THE STOP SIGN AND INTO THE INTERSECTION. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING 5 MPH SHE SMELLED A STRONG GASOLINE ODOR. THE VEHICLE WAS INSPECTED AND THERE WERE NO VISIBLE LEAKS. THE DEALER AUTHORIZED THE TOW TRUCK TO RETRIEVE THE VEHICLE SINCE SHE WAS AFRAID TO DRIVE IT. THE DEALER TEST DROVE THE VEHICLE AND DID NOT FIND ANY LEAKS OR DETECT ANY GASOLINE ODOR. THE FAILURE AND THE CURRENT MILEAGES WERE 7,000. UPDATED 03/09/10. *LJ UPDATED 05/12/10.8JB

OWN A 2010 PRIUS. HAVE EXPERIENCE INTERMITTENT BRAKE ISSUES. THE BRAKES SEEM TO NOT FUNCTION PROPERLY WHEN THEY APPLIED OVER UNEVEN SURFACES. THE CAR FEELS LIKE IT IS "SLIDING" OR "HYDROPLANING" FOR A BRIEF MOMENT, THEN THE BRAKES "CATCH" AGAIN. I WAS INVOLVED IN AN ACCIDENT ON SEPTEMBER 24, 2009 AND NEVER THOUGHT ABOUT THE ISSUE WITH THE BRAKES. *TR

DISCUSSION THREAD CUSTOMER 02/03/2010 01:04 PM I HAVE HEARD/READ OF A FEW INSTANCES OF BRAKING ISSUES WITH PRIUS'. I WOULD LIKE TO LET YOU KNOW I EXPERIENCED THIS PROBLEM THE OTHER DAY. I WAS APPROACHING A STOP LIGHT AT A SLOW RATE OF SPEED (~20) AND BRAKING LIGHTLY WHEN I WENT OVER A SMALL BUMP ACROSS THE ROAD. THE BRAKES/PEDAL IMMEDIATELY FELT USELESS. I QUICKLY LET UP ON THE PETAL AND HIT THE BRAKES MUCH HARDER AND I WAS ABLE TO SAFETY COME TO A STOP WITHOUT ANY DANGER OR LOCKING THE BRAKES. I WANTED TO BE SURE TO LET YOU KNOW AND BE ON RECORD OF THIS ISSUE WITH MY NEW PRIUS WHICH I LOVE SO FAR SHORT OF THIS INCIDENCE. IS THERE A KNOWN ISSUE OR FIX THAT I CAN HAVE MY DEALERSHIP LOOK INTO? *TR
