2008 Toyota Sienna Brakes Problems

Vehicle starting beebing and automatically engaged abs braking on highway. Dry and clear.

The dashboard lights up. abs and traction control light, vsc and brake. It seems like the bushings by the rack and pinion become loose and leads to random brake failure.

The vsc begins to beep and then the car sometimes applies brakes, or the motor seems to lug. This can happen at any any speed. This has been happening for years and is becoming more frequent.

BRAKE PEDAL WOULD GO TO FLOOR AND EXPERIENCED NO BRAKING. DEALER STATED "BRAKE COMPONENTS SEIZED AND INTERNAL FAILURE IN MASTER CYLINDER"

WHILE PUTTING ON THE BRAKES TO STOP FOR A TRAFFIC LIGHT THE ENGINE SUDDENLY REVVED UP TO 6000 RPM AND TRIED TO TAKE OFF BY ITSELF. I PUSHED THE GEAR SHIFT INTO NEUTRAL AND PUT MY LEFT FOOT ON THE BRAKE TO KEEP THE CAR FROM MOVING. I KICKED THE ACCELERATOR PEDAL SEVERAL TIMES UNTIL IT DISENGAGED. THIS IS THE 4TH TIME THIS HAS HAPPENED. THERE WAS NOT A FLOOR MAT INVOLVED AS THERE WAS NOT ONE IN THE CAR AT THIS TIME. THE LAST TIME I TALKED TO A TOYOTA DEALER ABOUT THIS THEY SAID THIS COULD NOT HAPPEN AND I WAS WRONG ABOUT WHAT HAPPENED. THE DEALER DID NOT DOCUMENT ANY OF THIS AND WANTED NOTHING FURTHER TO DO WITH ME. THIS IS DANGEROUS AND HAPPENS WITH NO WARNING WHEN YOU PUSH THE BRAKE PEDAL TO STOP FOR A TRAFFIC SIGNAL OR TO PULL INTO A PARKING SPACE. MY WIFE WAS ALSO IN THE CAR TWO OF THE TIMES AND SAW WHAT HAPPENED. SHE WAS NOT IN THE CAR FOR THE LATEST EPISODE.

TRACTION LIGHT NOTIFIED ME OF A BRAKE PROBLEM. VAN WOULD STOP AND LOCK THE BRAKES. DEALER DETERMINED THE PROBLEM WAS THE ABS BRAKE ACTUATOR. REPLACED IN JUNE OF 2015. VAN WAS BEING DRIVEN ON CITY STREET

I WAS DRIVING 35 MPH ON AT LEAST 4 SEPERATE OCCASSIONS WHEN MY I APPLIED MY BRAKES, THEY COMPLETELY FAILED. I TOOK IT BACK TO TOYOTA AND THEY KEPT IT FOR 10 DAYS, FLUSHED THE BRAKE LINES 4 TIMES, REPLACED THE MASTER CYLINDER, CHARGED ME $600 AND MADE ME SIGN A FORM SAYING THE VAN WAS UNSAFE TO DRIVE BECAUSE THEY HAVE NO IDEA WHAT WAS WRONG WITH IT.

DURING A RECENT TRIP TO ALABAMA FROM VIRGINIA, OUR 2008 TOYOTA SIENNA SUDDENLY ACCELERATED WHILE PRESSING THE BRAKE PEDAL INSTEAD OF BRAKING. BOTH TIMES, WE WERE APPROACHING MODERATELY HEAVY TRAFFIC. MY WIFE WENT TO APPLY THE BRAKES TO SLOW THE VAN. INSTEAD OF BRAKING AND SLOWING THE VEHICLE, THE VAN WENT INTO FULL ACCELERATION MODE. THE TRANSMISSION DOWNSHIFTED AND STARTED APPLYING FULL THROTTLE. THE FIRST TIME WE THOUGHT WE WERE GOING CRAZY. THE SECOND TIME, BOTH MY WIFE AND I WATCHED AS HER FOOT APPLIED THE BRAKES AND TO OUR AMAZEMENT, THE VAN STARTED ACCELERATING AGAIN! LUCKILY BOTH TIMES, MY WIFE TOOK HER FOOT OFF THE BRAKE PEDAL AND REAPPLIED ONCE THE VAN STOPPED ACCELERATING AND THE BRAKES WORKED THEN. I HAVEN'T HAD TIME TO TAKE THIS INTO THE TOYOTA DEALER YET. WE ARE STILL UNDER A 30 DAY WARRANTY WITH CARMAX, SO I HAVE COMMUNICATION OUT TO THEM TO SEE HOW WE SHOULD HANDLE THIS SITUATION. I THOUGHT THIS TOYOTA SUDDEN ACCELERATION STORY WAS EXAGGERATED. NOW I'VE EXPERIENCED IT MYSELF. *TR

I DRIVE ABOUT 5,000 MILES A YEAR, IN THE BEGINNING OF 2012 I WAS TOLD MY BRAKES DID NOT PASS THE STATE INSPECTION. AT THIS TIME I HAD AROUND 20000 MILES ON THE VAN. THE REASON OF THE REJECT WAS RUST ON THE ROTORS, IT WAS SO BAD AND THE ROTORS WERE SO THIN AND OF A POOR METAL, THEY COULD EVEN BE WORKED ON. I HAD TO REPLACE THE ROTORS AND PADS ON ALL 4 WHEELS. *TR

3/12/11 I WAS DRIVING AT 55 MPH ON STATE RT 104 IN COLUMBUS OHIO WHEN I HAD TO GET ON MY BRAKES HEAVILY TO AVOID HITTING A VAN THAT WAS TURNING IN FRONT OF ME, THE FOLLOWING CAR DID NOT STOP AND COLLIDED WITH ME FORCING ME INTO THE VAN IN FRONT CAUSING HEAVY DAMAGE TO THE REAR VEHICLE AND TO MINE . IMMEDIATELY DURING THE ACCIDENT MY BRAKES FAILED AND I WAS UNABLE TO AVOID HITTING THE VAN IN FRONT UNTIL I WAS ABLE TO THINK TO PUT MINE IN PARK TO STOP THE VEHICLE A FEW MINUTES LATER I TRIED MY BRAKES AGAIN AND THEY WERE O.K. I FEEL THE ANTILOCK BRAKES FAILED EITHER BECAUSE I WAS INTO THEM OR DUE TO MY VEHICLE BEING HIT SO HARD FROM THE REAR. MY VEHICLE IS A 2008 TOYOTA SIENNA VAN. THE VEHICLE THAT HIT ME WAS A 1997 HONDA CIVIC THE VEHICLE I HIT WAS A DODGE CARAVAN YEAR UNKNOWN. *TR

PROBLEM WITH REAR DISC BRAKES IN 2008 TOYOTA SIENNA. DEALER FOUND PROBLEM WITH CALIPER PISTON. RUST ON CLIP APPARENTLY CAUSED THE CALIPER PISTON TO STAY EXTENDED AND KEEP THE DISC BRAKE PAD IN CONTACT WITH THE BRAKE. REAR BRAKES FAILED AT 33K MILES. REPAIR PERFORMED AT CUSTOMER EXPENSE. SERVICE PERSON SAID WARRANTY DID NOT COVER BRAKE FAILURE BECAUSE IT WAS "CAUSED BY RUST." BRAKE FAILURE OCCURRED APPROXIMATELY ONE MONTH AFTER THE 30K MILE SERVICE. *TR

DURING A 30,000 MILE CHECK UP ON OUR 2008 TOYOTA SIENNA ALL WHEEL DRIVE VAN, WE HAD TO REPLACE THE FRONT AND REAR BREAKS BECAUSE THEY WERE GROUND DOWN AND DANGEROUS, ACCORDING TO OUR TOYOTA DEALER WHERE THE REPAIRS WHERE MADE. PADS HAD TO BE REPLACED, ROTORS HAD TO BE GROUND DOWN FOR BOTH FRONT AND REAR. ALL THE MILEAGE IS LONG DISTANCE HIGHWAY DRIVING. THERE WAS NO ACCIDENT BUT THE DEALER SEEMED VERY CONCERNED. *TR

2008 TOYOTA SIENNA LE, PURCHASED NEW. AT 5K MILES 1/2 TREAD WAS GONE ON FRONT TIRES PER REPAIR TECH NOTES. AT 15K FRONT TIRES WERE 2MM INSIDE AND BALD ON THE OUTSIDE, AND FRONT BRAKES WERE AT 1MM, ROTORS HAD TO BE REPLACED AS WELL. WENT BACK TO DEALERSHIP DUE TO NOISE COMING FROM BRAKES TWICE. CURRENT MILEAGE IS 33K AND THE VAN NEEDS NEW FRONT TIRES AND FRONT BRAKES (ROTOR?); ALL RECOMMENDED SERVICING WAS DONE (PER OWNERS MANUAL) AND IS DOCUMENTED. THIS VAN HAS A PERMANENT DEFECT. *TR

2008 TOYOTA SIENNA VAN. BRAKES ARE SOFT AND HAVE GOTTEN PROGRESSIVELY WORSE WITH TIME. AT 29000 MILES THE BRAKE PEDAL FADES COMPLETELY TO THE FLOOR. THE DEALER EXAMINED THE VEHICLE AND REPLACED THE REAR BRAKE PADS, THE FRONT BRAKE PADS ARE LOW BUT STILL WITHIN SPECIFICATIONS. THE MECHANIC STATES THAT THE CONDITION IS ACCEPTABLE. THIS CONDITION EXISTS AT ALL TIMES, WITH THE VEHICLE RUNNING OR NOT, STANDING STILL OR MOVING. HAVE NOT TRIED A PANIC STOP TO DETERMINE IF THE VEHICLE WILL STOP WITHIN A REASONABLE DISTANCE. *TR

THIS HAPPENED YESTERDAY JULY 10, 2010 SATURDAY IN THE REGIONAL PARKS PARKING LOT. SINCE IT'S UNPAVED SO THERE WAS ROCKS AND DIRT ON THE GROUND SO I WAS DRIVING EXTREMELY SLOW TO COME TO A STOP AT A SPOT TO PARK ' I WAS DRIVING WAY BELOW 5 MPH AND EVEN SLOWER WHEN I WAS ABOUT TO COME TO STOP ' AS I ALSO KNOW OUTSIDE OF THE WIRE FENCE, BEYOND THE NARROW ROAD, IT WAS A CLIFF WITH A SUBSTANTIAL DROP OF ELEVATION; AND I HAVE MY WHOLE FAMILY IN THE CAR. I WAS DRIVING A TOYOTA SIENNA MINI VAN WHICH I HAVE BEEN A LOYAL CUSTOMER AND A BIG BELIEVER OF THE QUALITY. JUST AROUND THE TIME THE CAR IS ABOUT TO STOP, ALL OF A SUDDEN, IT SPED UP FORWARD IN SUCH A FORCE WE WERE ALL PUSHED BACK AGAINST THE SEAT BACK, I IMMEDIATELY MOVED MY FOOT TO THE BRAKE AND PRESS ALL THE WAY BUT IT WAS NOT RESPONSIVE AND DID NOT SLOW THE CAR. INSTEAD, THE CAR SPED UP AND WENT THROUGH THE WIRE FENCE AT ABOUT 45 DEGREE ANGLE, WHILE I WAS STEERING TOWARDS LEFT TO AVOID IT WITH VERY LITTLE EFFECT, AND DROPPED DOWN THE SLOPE ONTO THE ROAD, ALL THE WHILE KEPT SPEEDING UP, AND THEN GOT ACROSS THE ROAD AND HIT A WOODEN POLE ON THE ROAD SIDE BY THE CLIFF STRAIGHT ON. THEN THE CAR STOPPED AND THE BRAKE SEEMED TO WORK AGAIN AS MY RIGHT FOOT WAS PUSHING ALL THE WAY DOWN ON THE BRAKE FOR THE WHOLE TIME ' SO I SHIFTED TO PARK, TURNED OFF THE ENGINE, AND THEN OPEN THE DOOR TO TELL PEOPLE COMING UP THAT WE WERE FINE. SOMEONE CALLED THE HIGH WAY PATROL AND THE OFFICER ARRIVED LATER TO TAKE THE CASE AND LATER TRANSFER THE CASE TO THE PARK POLICE FOR REPORT. THE CAR WAS TOWED TO A BODY SHOP AND MOST LIKELY IS TOTALED. WE HAVE INSURANCE COVERAGE SO THE FINANCIAL DAMAGE TO US WASN'T BIG. BUT WE ARE REALLY CONCERNED OF WHAT HAS HAPPENED. WE WERE SO LUCKY TO HAVE ESCAPED THE DROP DOWN THE CLIFF AND EXTREMELY LUCKY THAT WE DID NOT HIT ANYONE ALONG THE WAY, EVEN THOUGH IT WAS ONLY A FEW SECONDS (MAYBE 3-5 SECONDS) BUT THIS WAS A CROWDED PARK AND THERE WERE MANY BIKERS BIKING ALONG THE ROAD. *TR

TL*THE CONTACT OWNS A 2008 TOYOTA SIENNA. WHILE DRIVING APPROXIMATELY 45 MPH IN HEAVY RAIN, THE CONTACT APPLIED THE BRAKES AND THE VEHICLE LOST CONTROL WHICH RESULTED IN A CRASH. THERE WERE NO INJURIES. A POLICE REPORT WAS FILED. THE VEHICLE WAS DESTROYED. THE FAILURE HAD NOT BEEN DIAGNOSED. THE CURRENT AND FAILURE MILEAGES WERE APPROXIMATELY 50,000.

I HAVE A 2008 TOYOTA SIENNA AWD. SATURDAY AFTERNOON I WAS DRIVING EAST ALONG LEE HIGHWAY IN ARLINGTON, VA (PROBABLY MOVING AT ABOUT 30 TO 35 MPH) WITH MY TWO SMALL CHILDREN, AND I SLOWED AS I APPROACHED THE INTERSECTION WITH HARRISON STREET (WHICH IS A RATHER BUSY INTERSECTION). MY TRAFFIC LIGHT WAS RED, SO I NEEDED TO STOP. I APPLIED THE BRAKES FULLY, AND THE CAR CONTINUED TO SLOW, BUT IT DID NOT STOP FULLY. I RELEASED THE BRAKE AND THEN PUSHED IT HARD ALL THE WAY TO THE MAT, BUT THE CAR STILL CONTINUED TO INCH FORWARD. I BECAME FRIGHTENED AND THREW THE CAR INTO PARK AND HIT THE EMERGENCY BRAKE. THE CAR SEEMED TO STOP, BUT I TURNED OFF THE IGNITION JUST IN CASE. I WAS A FEW MINUTES FROM HOME, SO I DROVE HOME WITH MY HAZARDS ON AND PARKED THE CAR. I HAVE NOT DRIVEN IT SINCE. I CALLED THE DEALERSHIP THAT HAS BEEN PRIMARILY SERVICING THE VEHICLE (KOONS ARLINGTON), AND WAS TOLD TO CALL TOYOTA HEADQUARTERS - 800.331.4331. I CALLED THIS NUMBER FOR HEADQUARTERS, BUT AFTER REMAINING ON HOLD FOR OVER 5 MINUTES WITH NO END IN SIGHT AND WITHOUT HEARING A LIVE PERSON, I HUNG UP AND TRIED THE DEALERSHIP AGAIN. A SERVICE REPRESENTATIVE TOLD ME TO HAVE THE VEHICLE TOWED TO THE DEALERSHIP, WHICH I DID EARLY THIS MORNING. I AM AWAITING A RESPONSE FROM THE DEALERSHIP. I EMAILED THEM FOR A STATUS UPDATE EARLIER THIS AFTERNOON. *TR

BRAKES DID NOT RESPOND. COMING TO A RED LIGHT I APPLIED BRAKES WITH NO RESPONSE, SHIFTED TO NEUTRAL AND APPLIES BRAKES AGAIN. NO REACTION. :( RESULTED IN REAR ENDING ANOTHER VEHICLE. *TR

AFTER 200 MILES WE NOTICE THAT WE CAN'T CONTROL THE CAR ON TIME. WE GO THE NEAR BY TOYOTA DEALERSHIP. THEY TOLD ME THEY CHECKED THE BRAKES AND TOLD ME THAT EVERYTHING IS FINE. WHEN WE WENT BACK TO CHICAGO AGAIN WE WENT TO THE DEALERSHIP THEY GIVE THE SAME ANSWER. NOW WE ARE DRIVING THE CAR SLOWLY AND SO CAREFULLY. I THINK MY CAR IS HAVING THE SAME ISSUES THE OTHER TOYOTA CARS HAVING. PLS DO THE SOMETHING. *TR
