SERVICE BRAKES, HYDRAULIC
THIS IS A COMPLAINT ABOUT A RECURRING EVENT THAT HAS SERIOUS IMPLICATIONS IN THE WRONG SITUATIONS. FOR FIVE TIMES NOW, SINCE DRIVING OUR NEW CAR, OUR BRAKES HAVE RELEASED AFTER GOING OVER A BUMP IN THE ROAD. THIS BUMP CAN BE AS SMALL AS A CRACK CAUSED BY A NEARBY TREE'S ROOTS, OR LARGER LIKE A POTHOLE. IT HAS ALSO OCCURRED WHEN DRIVING OVER SLICK SEWER COVERS. IT TYPICALLY HAPPENS WHEN BRAKING, THEN HITTING THE BUMP, THEN BRAKES RELEASE, AND THE CAR IS NO LONGER BREAKING. THIS IS ESPECIALLY DANGEROUS IN HILLY CITIES LIKE SAN FRANCISCO, WHERE IF THIS HAPPENS GOING DOWNHILL, THE ACCELERATION ACCOMPANIED BY THE LACK OF BRAKING GOING DOWNHILL CAN RESULT IN CRASHING INTO THE NEXT CAR, OR WORSE, HITTING A CROSSING PEDESTRIAN AT A CROSS WALK. *TR

I OWN A 2010 TOYOTA PRIUS THAT SEEM TO LOOSE BRAKING POWER WHEN I HAVE THE BRAKE PEDAL PRESSED DOWN AND THEN HIT A POTHOLE OR MANHOLE COVER. IT HAPPENS ALL THE TIME. WHEN I TOOK IT INTO THE DEALER A FEW MONTHS AGO THEY DIDN'T FIND A PROBLEM, BUT IT APPEARS TO BE A COMMON PROBLEM FOR THIS MODEL. *TR

WHILE BRAKING IF I HIT POTHOLES THE CAR SPEEDS UP FROM LOSS OF BRAKING ACTION EVEN THOU I AM STILL PUSHING ON THE BRAKE PEDAL. I HAVE TO QUICKLY LET UP AND APPLY BRAKES AGAIN TO STOP VEHICLE. HAS HAPPENED THREE TIMES NOW, TWICE IN THE LAST TWO DAYS. FIRST TIME THOUGHT IT WAS MY IMAGINATION, BUT NOW I KNOW THAT I WAS PUSHING ON THE PEDAL AND THE CAR JUST TOOK OFF UNTIL I REAPPLIED THE BRAKES. *TR

SERVICE BRAKES, HYDRAULIC
THERE IS AN APPARENT MOMENTARY LOSS OF BRAKING ABILITY THAT WE HAVE EXPERIENCED SEVERAL TIMES. GOING OVER A RISE IN THE ROAD, OR BUMPS, AND BEGINNING A DESCENT TO AN INTERSECTION, PRESSING THE BRAKE PEDAL SEEMS TO HAVE NO EFFECT FOR ABOUT 500MS. THIS SEEMS SOMEWHAT MORE PRONOUNCED WHEN THE ROAD IS WET, ALTHOUGH POSSIBLY THE EXPLANATION FOR THIS IS WE BRAKE EARLIER IN THE DESCENT AS A PRECAUTION IN LESS-THAN-IDEAL CIRCUMSTANCES. WE HAVE MADE OUR LOCAL DEALER AWARE OF THIS AT THE 5K MILE SERVICE APPOINTMENT, AND THEY ACKNOWLEDGED OTHER COMPLAINTS, AND CONTACT WITH TOYOTA. THEY REPORT THAT TOYOTA IS LOOKING IN TO A FIX. WE ARE CONCERNED ABOUT THE ABILITY TO BRAKE IN AN EMERGENCY SITUATION WITH NO SAFETY MARGIN. THIS SEEMS REPRODUCIBLE. *TR

MY HUSBAND AND I RECENTLY PURCHASED A 2010 TOYOTA PRIUS. WE HAVE NOTICED REPEATED PROBLEMS WITH THE BRAKING SYSTEM. WHENEVER WE GO OVER A POTHOLE WHILE BRAKING, THE CAR SURGES FORWARD. THIS DOES NOT JUST APPEAR TO BE A PROBLEM WITH THE PRESSURE ON THE BRAKE PEDAL; THE PASSENGER CAN FEEL THE SURGE AS WELL. THIS PROBLEM IS QUITE ALARMING. WE ARE TAKING THE CAR TO THE DEALER TODAY TO ADDRESS THIS ISSUE. *TR

I HAVE A 2010 PRIUS PURCHASED IN SEPTEMBER OF 2009. IT NOW HAS JUST OVER 5000 MILES ON IT. SINCE THE BEGINNING, PROBABLY THE FIRST WEEKEND I OWNED THE CAR, WHEN BRAKING IF I HIT A BUMP IN THE ROAD, UNEVEN SURFACE, OR A POTHOLE OR SOMETHING, THE CAR OFTEN FEELS LIKE IT LURCHES FORWARD AND I HAVE TO IMMEDIATELY RELEASE AND REBRAKE. THE CAR FEELS OUT OF CONTROL. I HAVE VERY OFTEN FELT LIKE I NARROWLY MISSED LURCHING FORWARD INTO THE CAR IN FRONT OF ME. THE TOYOTA DEALERSHIP SERVICE DEPARTMENT INSISTS THEY ONLY KNOW OF RECALLS REGARDING THE STICKING ACCELERATOR PEDALS, NOTHING ABOUT THIS BRAKING ISSUE. YET I READ PLENTY ONLINE ABOUT THIS PROBLEM, SO I KNOW IT ISN'T ONLY HAPPENING TO ME. WHAT CAN YOU DO?? I'VE LISTED ALL THREE TYPES OF BRAKES IN THE EQUIPMENT AREA OF THIS FORM, BECAUSE I DON'T KNOW WHAT IT IS - SOMETHING ABOUT THE HYBRID BRAKING SYSTEM ALSO CHARGING THE ENGINE? ALSO I LISTED THE DATE AS THE DAY AFTER I BOUGHT THE CAR BUT THIS IS ONGOING, NOT A SINGLE INCIDENT BY ANY MEANS. *TR

WHILE ACCELERATING TO MAKE A RIGHT HAND TURN SIGNAL (SPEED APPX 30MPH) I DEPRESSED THE BRAKES TO SLOW THE VEHICLE DOWN TO A REASONABLE SPEED TO SAFELY MAKE THE TURN, THE CAR SLOWED, I BEGAN THE TURN BUT MID- TURN WITH MY FOOT STILL DEPRESSING THE BRAKE PEDAL THE CAR MADE A 1 ' 2 SECOND ACCELERATION. *TR

AT A RIGHT TURN I ENCOUNTERED A POTHOLE AND APPLIED THE BRAKES. WHEN MY CAR ACTUALLY HIT THE POTHOLE I FELT, FOR A VERY BRIEF TIME, THAT THE BRAKES DIDN'T WORK AND THE ENGINE REV UP A LITTLE BIT. I WAS DRIVING AT LOW SPEED. I COULD HAVE HIT THE CAR IN FRONT OF ME. *TR

1. EVENTS LEADING UP TO FAILURE: MODERATE BRAKING (~0.2 - 0.4 G) AT MODERATE SPEED (~20 MPH) WHILE DRIVING OVER CHOPPY PAVEMENT SUCH AS MIGHT EXIST WHERE ROAD WORK IS BEING DONE. 2. FAILURE: AS THE CAR PASSES OVER THE CHOPPY PAVEMENT, BRAKING FORCE DECLINES SHARPLY WITHOUT A CHANGE IN BRAKE PEDAL PRESSURE. THE CONSEQUENCE OF THIS IS THAT THE CAR STOPS FARTHER DOWN THE ROAD THAN EXPECTED DESPITE REFLEXIVE INCREASED BRAKE PRESSURE ON MY PART. THIS HAS HAPPENED THREE TIMES IN 7500 MILES OF VERY MODERATE DRIVING. SO FAR I HAVE NOT HAD A COLLISION OR OTHER ACCIDENT FROM THIS UNEXPECTED BEHAVIOR. I HAVE NEVER EXPERIENCED THIS BEHAVIOR IN ANY OTHER CAR INCLUDING DOZENS OF RENTAL CARS. 3. WHAT WAS DONE TO CORRECT THE FAILURE. NOTHING. TW*

WHEN BREAKING MY 2010 TOYOTA PRIUS, IF I GO OVER A BUMP OR POT HOLE, IT FEELS LIKE THE BRAKES CUT OUT AND MY CAR JOLTS FORWARDS. IT SEEMS TO HAPPEN ONLY WHEN I GO OVER A BUMP OR SOMETHING THAT WOULD SHAKE THE CAR A BIT. NOTHING HAS BEEN DONE AS OF YET TO CORRECT THE PROBLEM. TW*

I WAS DRIVING ON CITY STREETS, AND COMING TO A STOP SIGN. I STARTED BRAKING, AND WHILE BRAKING, I HIT A SMALLISH POTHOLE. IT FELT LIKE MY BRAKES STOPPED WORKING. FORTUNATELY THE BRAKES STARTED WORKING AGAIN BEFORE WE REACHED THE INTERSECTION. I THINK WE WERE DRIVING 25 MPH WHEN THIS HAPPENED. THIS IS THE FIRST TIME IT HAS HAPPENED IN OUR NEW CAR WHICH IS ONLY 1 MONTH OLD. THIS WAS IS SCARY FEELING, AND UNLIKE ANY OTHER I'VE FELT. IT WAS NOT "ANTI-LOCK" BRAKES, AS I'VE EXPERIENCED THAT BEFORE.*CW

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHENEVER THE VEHICLE TRAVELS OVER A ROUGH TERRAIN AT ANY SPEED THE CONTACT NOTICED THAT THE BRAKE PEDAL RELEASED CAUSING THE VEHICLE TO SUDDENLY ACCELERATE. THE BRAKING DISTANCE AND PRESSURE APPLIED TO THE BRAKE PEDAL ALSO INCREASED IN ORDER TO STOP THE VEHICLE. THE DEALER STATED THAT THE FAILURE COULD NOT BE REPRODUCED. THERE WERE NO PRIOR WARNINGS. THE CURRENT AND FAILURE MILEAGES WERE 8300.

I NOTICED THAT THE CAR LURCHES FORWARD WHENEVER DRIVEN ON A MANHOLE, OR A ROUGH PATCH ON ROAD, OR A SPEED HUMP DESPITE THE BRAKING. THOUGH I REGAIN CONTROL WITHIN SECONDS, THE MOMENT OF LURCH IS SCARY AND MAKES ME FEEL UNSAFE IN OTHER TRAFFIC SITUATIONS. THIS HAPPENS AT ALMOST ALL SPEEDS. I GUESS FROM NOW ONWARDS I WILL MAINTAIN ENOUGH GAP BETWEEN THIS CAR AND THE FORWARD ONE AS I SEEM TO BE NOT ABLE TO TRUST THIS CAR ANY FURTHER. PERHAPS I WILL NEVER RECOMMEND THIS CAR OR ANY TOYOTA TO ANYONE IN FUTURE. *CN

MY 2010 TOYOTA PRIUS 1) LURCHES FORWARD WHEN BRAKING WHILE DRIVING ON AN UNEVEN SURFACE, LIKE A POTHOLE, INDENT/CREVICE IN ROAD, ETC. 2) THE BRAKES REPEATEDLY GRAB AND CAUSE THE CAR TO LURCH WHEN BACKING UP ON AN UNEVEN/SLIPPERY SURFACE. BOTH PROBLEMS SEEM TO HAPPEN WHEN APPLYING PRESSURE AND BRAKING AT A SLOWER SPEED. THIS PROBLEM HAS OCCURRED MULTIPLE TIMES (APPROXIMATELY 4-5) SINCE PURCHASING THE PRIUS IN JUNE 2009. *CN

WHEN THE CAR GOES OVER AN UNEVEN OR BUMPY [SURFACE,] OR DOWN AN INCLINE, THE CAR ACCELERATES OR LURCHES FORWARD. THIS HAS OCCURRED SEVERAL TIMES AND IS UNNERVING TO THE POINT I HAVE SWITCHED CARS WITH MY HUSBAND. ALSO, WHEN COMING OUT OF MY GARAGE MOST EACH DAY, THE CAR ROLLS BACK ON BATTERY POWER, BUT THE BRAKES ARE STIFF, JUST LIKED YOU WOULD PUMP THEM WHEN THE CAR IS OFF (REAL HARD) UNTIL THE CARS MOTOR TURNS ON. BUT BY THEN, YOU HAVE ROLLED 15 OR SO FEET BACKWARD WITH LITTLE TO NO BREAK CONTROL. THEY FEEL LIKE THEY WON'T STOP THE CAR. *TR
