2009 Toyota Prius SERVICE BRAKES, ELECTRIC

I BOUGHT A 2009 TOYOTA PRIUS IN MARCH 2009. ON SEVERAL OCCASIONS, WHILE BRAKING OVER ROUGH ROADWAYS, THE BRAKES HAVE SEEMED TO SKIP (AND THE ABS DASHBOARD LIGHT COMES ON). MY WIFE HAS ALSO EXPERIENCED THE SAME ISSUE SEVERAL TIMES. WHILE WE INITIALLY THOUGHT IT WAS DUE TO THE ROAD CONDITIONS, AFTER THE ANNOUNCEMENTS REGARDING THE BRAKE ISSUE WITH THE 2010 MODEL, I HAD TO REPORT THAT THIS ISSUE IS ALSO PRESENT IN MY 2009 MODEL. *TR

WAITING FOR MY HUSBAND AT HIS MOTHER'S ASSISTED LIVING RESIDENCE, I PUT MY 2009 PRIUS IN PARK MODE. DECIDING TO RETURN TO THE BLDG ENTRANCE, I PUT THE CAR IN REVERSE (OUT OF PARKING MODE) AND LET IT GO AT ITS OWN SPEED. MY FOOT NEVER TOUCHED THE ACCELERATOR. I WAS ABOUT TO TURN THE WHEEL TO REENTER THE ENTRANCE AREA, WHEN THE CAR STARTED TO ACCELERATE. I QUICKLY PUT MY FOOT ON THE BRAKE BUT THE BRAKES DIDN'T WORK. I THEN SAW A WOMAN IN THE REAR VIEW MIRROR, ABOUT A FOOT FROM ME STANDING ON THE CURB IN FRONT OF THE BLDG'S GLASS FAADE. I TURNED THE WHEEL JUST MISSING HER AS WELL AS THE BLDG. FRANTICALLY PRESSING THE BRAKES WHILE THE CAR CONTINUED ACCELERATING MORE, I ALMOST WENT ON TO A BUSY ST. ACROSS FROM A MALL. SOMEHOW I SAVED MYSELF & OTHERS BY TURNING THE STEERING WHEEL TO THE RT, REENTERING THE PROPERTY VIA A CURB CUT FOR WHEELCHAIRS, ETC. I MISSED HITTING A POLE BUT RAN OVER 2 TREES, WHICH THE CAR SEVERED & WHICH ABRUPTLY STOPPED THE CAR, JUST BEFORE HITTING A BRICK WALL. THIS ALL HAPPENED AT NIGHT, IN THE DARK, IN REVERSE.THE POLICEMAN & THE TOW TRUCK OPERATOR WERE INCREDULOUS HOW THE CAR GOT INTO THAT SPACE. IT WAS TOWED TO A NEARBY TOYOTA DEALER, WHERE THE BRAKES WERE PRONOUNCED "PERFECT". SO MY HUSBAND INSISTED I BE CHECKED OUT. WHILE RELATING THE INCIDENT TO THE DOCTOR, THE DR. GOOGLED "PRIUS BRAKE/ACCELERATION PROBLEMS" & FOUND MANY & PRINTED 1 OF A 2009 PRIUS WHERE THE DRIVER ENCOUNTERED 3 SUCH OCCURRENCES "DUE TO A COMBINATION OF MYSTERIOUS ACCELERATION AND LOSS OF BRAKES". THE DR. WAS CERTAIN I WAS THE 'VICTIM", BUT SUGGESTED I HAVE AN MRI "TO BE SURE"--WHICH I DID & I'M FINE. THAT I WAS IN CONTROL IN A TOTALLY UNCONTROLLABLE SITUATION AT NIGHT WITH A CAR IN REVERSE, WHERE I ALMOST KILLED SOMEONE & POSSIBLY KILLED OR HURT OTHERS, INCLUDING MYSELF, AND DONE CONSIDERABLE DAMAGE ALONG THE WAY IS A MIRACLE AND THE CULPRIT, I'M CONVINCED, IS/WAS A "GLITCH" IN THE CAR'S COMPUTER. *TR

AT ALL SPEEDS BELOW 15MPH, THE PRIUS' ELECTRICAL BRAKING SYSTEM "PULSES" THE BRAKES RESULTING IN A DECELERATION THAT IS NOT SMOOTH. THE EFFECT IS SIMILAR TO THAT YOU MIGHT EXPECT AS THE TRANSMISSION DOWNSHIFTS. BUT...THE TRANSMISSION EFFECT CAN BE ELIMINATED SINCE THE BRAKE PULSING EFFECT REMAINS AFTER THE VEHICLE'S TRANSMISSION WAS PLACED IN NEUTRAL AND THE BRAKES WERE APPLIED. THE LOCAL ALBUQUERQUE PRIUS DEALERSHIP INDICATED THIS PULSING IS "NORMAL" FOR THE PRIUS. ON SLIPPERY PAVEMENT, THIS EFFECT COULD BE DEADLY. THE BRAKING SHOULD BE SMOOTH THROUGHOUT THE BRAKING CYCLE. IT IS NOT. DISREGARD DATE - THIS IS AN ONGOING PROBLEM. *TR

MY COMPANY PROVIDES FOR ME A 2009 TOYOTA PRIUS AND IT HAS BEEN MY PRIMARY VEHICLE FOR THE PAST 36,000 MILES. I'VE NOTICED BRAKING ISSUES EVER SINCE I GOT IT BRAND NEW AT THE DEALERSHIP. THE BRAKES NORMALLY WORK EXCEPTIONALLY WELL. THIS CAR STOPS EXTREMELY WELL UNDER NORMAL CONDITIONS. HOWEVER, IF WHILE BRAKING, I HIT ANY TYPE OF BUMP OR HOLE OR ANY RUMBLE STRIPS OR ANYTHING LIKE THAT, THE CAR FEELS LIKE THE BRAKES JUST GO AWAY. SOMETIMES IT EVEN FEELS LIKE THE CAR BEGINS TO ACCELERATE FOR A BRIEF MOMENT! AGAIN, THIS ONLY HAPPENS IF I HIT A POTHOLE, BUMP, ETC. IT HAPPENS ENOUGH THAT I'VE THOUGHT OF SETTING UP AN EXPERIMENT OF RUNNING OVER A WHOLE ROW OF RUMBLE STRIPS JUST TO SEE IF THE CAR WOULD STOP AT ALL. IT'S ALMOST LIKE THE CAR WON'T BEGIN TO STOP UNTIL IT'S ON SMOOTH PAVEMENT AGAIN AFTER THE BUMPY PART. IT'S UNFORTUNATE BECAUSE UNDER NORMAL CONDITIONS THE PRIUS HAS EXCELLENT STOPPING POWER, IN MY OPINION. ANYWAY, THAT'S ABOUT IT. I CAN'T EXPLAIN IT MUCH BETTER THAN THAT. *TR

I HAVE A 2009 TOYOTA PRIUS HYBRID . OCCASIONALLY WHEN I STEP ON THE BRAKE THE CAR DOES NOT STOP IMMEDIATELY EVEN AT SLOW SPEEDS WHEN BRAKING. I NOW HIT THE BRAKES ABOUT 10 FEET BEFORE A STOP SIGN OR LIGHT, SO I WONT GO INTO THE ONCOMING LANE. I HAVE NOT TAKEN IT IN TO GET LOOKED AT YET. *TR

2009 PRIUS BRAKE FAILURE IN LESS THAN 1" SNOW COVERED ROAD. CAR SLID TO STOP WITH NO BRAKE CONTROL. PEDESTRIAN IN ROAD UNINJURED BECAUSE THEY MOVED OUT OF CAR PATH!! SECOND TIME NO BRAKE CONTROL IN SNOW. CAR HAD BEEN RECENTLY INSPECTED WITH NO BRAKE FINDINGS. WILL NO LONGER DRIVE CAR IN SNOW UNTIL REMEDIED. *TR

I KEEP HEARING ABOUT PRIUS BRAKE PROBLEMS ON 2010 MODELS BUT MY 2009 HAS THE SAME PROBLEM. I READ THIS IN AN ARTICLE ONLINE AND REALIZED THAT MY 2009 MODEL HAS THE BRAKING PROBLEM AS THE 2010 MODEL. ARTICLE: "GOING DOWNHILL AND APPROACHING A STOP SIGN. MY FOOT IS STEADY ON THE BRAKE AND I AM GRADUALLY COMING TO A STOP. THEN, I INADVERTENTLY GO OVER A BUMP IN THE ROAD AND THE PRIUS LUNGES FORWARD. I HAD TO IMMEDIATELY SLAM HARD ON THE BRAKES IN ORDER TO KEEP THE CAR FROM GOING INTO THE INTERSECTION. FORTUNATELY, THERE WAS NO CAR OR PERSON IN FRONT OF ME AS I WAS STOPPING." *TR

TL*THE CONTACT OWNS A 2009 TOYOTA PRIUS. WHILE DRIVING 5 MPH TOWARD A STOP SIGN AND APPLYING THE BRAKES, THE VEHICLE FAILED TO STOP. THE TRACTION CONTROL LIGHT ILLUMINATED AS SOON AS SHE REMOVED HER FOOT FROM THE BRAKE PEDAL. WHEN THE LIGHT WAS NOT ILLUMINATED, THE BRAKES FUNCTIONED NORMALLY. THE FAILURE MILEAGE WAS 50. THE CURRENT MILEAGE WAS 33,000.

BRAKING ISSUES WITH A 2009 TOYOTA PRIUS MODEL. UNDER ROUGH ROAD CONDITION THE BRAKE SYSTEM DOES NOT SEEM TO ENGAGE IMMEDIATELY CAUSING A OVERRUN OF THE DISTANCE NEEDED FOR THE VEHICLE TO STOP. *TR

THE CAR IN FRONT OF ME SLAMMED ON THE BRAKES AND I FOLLOWED SUITE. HOWEVER, AS HAD HAPPENED IN MANY OCCASIONS BEFORE THE BRAKES WERE DELAYED FOR A SECOND OR TWO AND THE LIGHT SHOWING THAT THE CARE IS SLIPPING CAME ON. AS USUAL IT FELT AS IF I WAS SLIDING ON ICE ALTHOUGH THERE WAS NONE. I DON'T KNOW IF I COULD HAVE STOPPED IN TIME BUT THE DELAY WAS DEFINITELY A FACTOR. *TR

HI THERE, I RENTED A NEW 2009 TOYOTA PRIUS. A COUPLE OF DAYS AGO AS I WAS DRIVING IN ONE OF THE INSIDE STREETS IN A NEIGHBORHOOD, I GOT INTO AN ACCIDENT EVEN THOUGH I WAS DRIVING WITH A LOW SPEED OF 15-20 MPH I REAR ENDED A CAR THAT SLAMMED ON THEIR BRAKES ALL OF A SUDDEN. I SLAMMED HARD ON MY BRAKES AND IT SKIDDED A LITTLE AND HIT THE VAN REAR END BUMPER AHEAD OF ME. THE ACCIDENT DID A QUITE A BIT OF DAMAGE TO MY RENTAL PRIUS. THE FRONT BUMPER OF THE CAR IS COMPLETELY DESTROYED AND WILL NEED TO BE REPLACED. I TOOK THE CAR BACK TO HERTZ AND THEY SWAPPED THE CAR; I TOLD HERTZ TO CHECK THE BRAKES THOROUGHLY; BECAUSE THERE IS A DEFINITELY A PROBLEM WITH THE BRAKES AT LOW SPEED. PLEASE HELP. EVEN THOUGH MY INSURANCE COMPANY WILL TAKE CARE OF THE DAMAGE; I AM CONCERNED ABOUT THE SAFETY OF THE OTHER PEOPLE IN THE SAME SITUATION OF LOW SPEED AND BRAKES DO NOT WORK. *TR
