2006 Toyota Sienna Brakes Problems

Your brake pedal may fail to engage when you decelerate, even though no warning lights appear on your dashboard. You might hear a strange noise and need to press the pedal hard before the antilock braking system (ABS) kicks in, though it may also fail. The brake pump has been replaced twice without resolving the issue, and diagnosis suggests the ABS system itself may need replacement.

Your ABS and traction control system activates every time you turn a corner, causing beeping and sudden brake engagement even when you're not actually sliding. This is dangerous because it interferes with normal braking while turning. You've found that unplugging the sensor under the front passenger seat stops the problem, but this also disables your airbags and other safety systems. The issue likely involves a faulty wheel speed sensor or its wiring that needs replacement or repair.

Your traction control and ABS system are activating unexpectedly while driving between 30-60 mph, especially on curved roads, causing the brakes to pump automatically and triggering a traction control alarm before stopping on its own. This is particularly dangerous in wet or icy conditions or when being tailgated. You've already replaced the front right wheel speed sensor without resolving the issue. The fix will likely involve diagnosing the ABS/traction control system, which may require checking other wheel speed sensors, the ABS module, or wiring connections.

I've had multiple instances of driving along at varying speeds ranging from 35 to 65 mph, where the traction control kicked in abruptly, the slip indicator lights come on along with the traction control light on the dashboard, a beeping sound occurs, and the van brakes suddenly on its own. This has happened on dry pavement without any reason for traction control to kick in whether I'm driving straight or going around a curve. It is very dangerous and I've stopped driving the vehicle since I often drive with my 3 young children and I fear for our safety.

WITH NO WARNING ABS WILL LOCK UP AND CAUSE VAN TO VIOLENTLY SWERVE TO THE RIGHT WHILE DRIVING. SOMETIMES ONCE , OTHER TIMES SEVERAL TIMES IN A ROW. ONLY LASTS FOR A FEW SECONDS. BUT LONG ENOUGH TO CAUSE AN ACCIDENT. TERRIFYING TO LOOSE COMPLETE CONTROL OF YOUR VEHICLE UNTIL IT DECIDES TO GIVE YOU CONTROL AGAIN. SEVERAL TRIPS TO DIFFERENT TOYOTA DEALERS AS WELL NO LESS THAN 5 DIFFERENT MECHANICS AND NO ONE HAS ANY IDEA WHAT CAUSES IT. HOWEVER THE TOYOTA DEALERS WERE ALL VERY FAMILIAR WITH THE ISSUE BUT HAD NO IDEA HOW TO FIX IT. THIS HAS BEEN GOING ON FOR 18 MONTHS. THE INTERNET IS FULL OF PEOPLE TRYING TO SOLVE THE SAME ISSUE IN 2004-2010 TOYOTA'S IN ALL MODELS. PLEASE HELP!

WHILE DRIVING IN A RESIDENTIAL AREA, GOING 5-10 MPH, THE ANTI-LOCK BRAKE LIGHT CAME ON FLASHING AND BEEPING LOUDLY. THE STEERING SYSTEM LOCKED UP AND LASTED 45 SECONDS TO 1 MINUTE. IT WOULD OCCUR ON A HIGHWAY AS WELL, NO REASON, GROUND COMPLETELY DRY. IT WOULD OCCUR DRIVING INTO THE PA TURNPIKE TOLL BOOTH, ROUNDING CORNERS, GOING STRAIGHT ON 65 MPH HIGHWAY, (IT OCCURRED INTERMITTENTLY 60-70 TIMES). THE DEALER (NORTH HILLS TOYOTA 7401 MCKNIGHT ROAD, PITTSBURGH, PA 15237 412-318-3000 WERE UNABLE TO FIX IT AFTER I TOOK IT IN TWICE. THE LAST TIME, THEY DISCONNECTED THE ANTILOCK BRAKE SYSTEM TO FIX THE PROBLEM. I CURRENTLY AM DRIVING WITH THE SYSTEM UNCONNECTED. *JS

THE CAR WAS SENT TO THE DEALER FOR TIMING BELT KIT REPLACEMENT, UPON INSPECTION THE TECHNICIAN FOUND THE ANTI LOCK BRAKE SYSTEM IS MALFUNCTIONING DUE TO THE FACT THE ABOVE MENTIONED PART, PART # 44050-08030, THE ANTI LOCK BRAKES HYDRAULIC UNIT, IS DAMAGE OR INOPERABLE.

TL* THE CONTACT OWNS A 2006 TOYOTA SIENNA. THE CONTACT STATED WHILE DRIVING APPROXIMATELY 5 MPH THE ANTI SKID BREAK LIGHT ILLUMINATED AND THE VEHICLE MADE A LOUD BEEPING SOUND. THE CONTACT WAS ABLE TO DRIVE THE VEHICLE TO HER RESIDENCE AFTER THE FAILURE OCCURRED. THE FAILURE OCCURRED SIXTY OR SEVENTY TIMES OVER A PERIOD OF ONE YEAR. THE VEHICLE WAS TAKEN TO A DEALER WHERE THE MECHANIC COULD NOT DIAGNOSE THE FAILURE, BECAUSE IT OCCURRED INTERMITTENTLY. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 84,000.

THE VEHICLE SUSTAINED INTERMITTENT BRAKE FAILURES. THE BRAKES WOULD FUNCTION NORMALLY, THEN COMPLETELY FAIL, THEN BEGIN FUNCTIONING NORMALLY AGAIN. THIS INCIDENT RESULTED IN A LOW SPEED COLLISION. THE INITIAL OCCURRENCE WAS AFTER DRIVING AT HIGHWAY SPEEDS FOR APPROXIMATELY 20 MILES AND BRAKING FOR STOPPED TRAFFIC. AFTER BRAKING TO APPROXIMATELY 10 MPH, THE BRAKES WERE RELEASED, AND THEN THE BRAKE PEDAL WAS APPLIED AGAIN. THERE WAS NO BRAKING EFFORT. THE DRIVER BEGAN PUMPING THE BRAKE PEDAL, AND WAS ABLE TO DO SO THREE TIMES BEFORE IMPACT. THE VEHICLE WAS THEN PLACED IN PARK AND AN ACCIDENT REPORT FILED. THE VEHICLE WAS THEN MOVED UNDER ITS OWN POWER TO A NEARBY PARKING LOT, DURING WHICH TIME THE BRAKES FUNCTIONED NORMALLY. THE VEHICLE WAS THEN TAKEN HOME. THE NEXT MORNING THE VEHICLE WAS BEING BACKED OUT OF THE GARAGE AND HAD ANOTHER COMPLETE BRAKE FAILURE. THE VEHICLE WAS STOPPED BY PLACING THE TRANSMISSION IN PARK. AT THIS TIME, THE VEHICLE IS SCHEDULED TO BE TOWED TO THE LARICHE TOYOTA DEALERSHIP IN FINDLAY, OHIO FOR DIAGNOSIS AND REPAIR. THE TELEPHONE NUMBER TO THEIR SERVICE DEPARTMENT IS 419-423-5656. *TR

I WAS DRIVING APPROXIMATE 25-30 MPH ON A DRY, LEVEL STREET. A CAR STOPPED IN FRONT OF ME TO MAKE A LEFT HAND TURN. I APPLIED THE BRAKES AND NOTHING HAPPENED. I RELEASED AND REAPPLIED THE BRAKES AGAIN AND AGAIN NO RESPONSE. I WAS ABLE TO SWERVE TO THE RIGHT INTO AN EMPTY PARKING LOT TO AVOID HITTING THE CAR OR ANOTHER COLLISION. AFTER SWERVING AND REAPPLYING THE BRAKES A 3RD OR 4TH TIME I WAS ABLE TO COME TO A STOP. MY KIDS AND I WERE SEVERELY SHAKEN, BUT NOT INJURED. WE DECIDED THIS PROBLEM WAS DUE TO THE MASTER CYLINDER. WE REPLACED IT AND HAVE HAD 3 MORE INCIDENTS SINCE REPLACING THE MASTER CYLINDER. 1 WAS IN REVERSE LEAVING MY DRIVE WAY. I WOUND UP HITTING AND EMBANKMENT ACROSS THE STREET TO STOP ME. THIS WAS A SLIGHT DOWN HILL ROLL IN REVERSE. I WENT FROM PARKED TO OUT OF CONTROL. I NEVER TOUCHED THE ACCELERATOR AND HIT THE BRAKE MULTIPLE TIMES AND EVEN TRIED SHIFTING BACK INTO PARK (KNOWING THAT'S BAD FOR THE TRANSMISSION), NOTHING WORKED. AFTER GETTING STOPPED AND PULLING FORWARD EVERYTHING SEEMED NORMAL AGAIN. MY HUSBAND WAS DRIVING IN TRAFFIC AND WE WERE APPROACHING A TURN AND HAD TO MERGE IN TO PERPENDICULAR TRAFFIC. APPROX SPEED 25-35 MPH. THE BRAKES AGAIN COMPLETELY FAILED AND WE HAD TO SWERVE THROUGH A TRAFFIC LIGHT IN TO A FREE LANE OF TRAFFIC TO AVOID A REAR END COLLISION WITH THE CARS INFRONT OF US. WE ORDERED ANOTHER MASTER CYLINDER AND WERE PREPARING TO INSTALL IT. TODAY THE BRAKES FAILED AGAIN AT A STOP SIGN (APPROX SPEED 5-10 MPH) I HAD BEEN STOPPED AND STARTED TO EASE IN TO THE MAIN ROAD WHEN I SAW A CAR COMING FROM THE LEFT. *TR

AS I WAS PROCEEDING DOWNHILL TOWARDS A 4-WAY STOP INTERSECTION AT THE BOTTOM OF THE HILL; I DEPRESSED THE BRAKE PEDAL AND NOTHING HAPPEN. I COULD NOT STOP THE CAR. A CAR WAS STOPPED IN FRONT OF ME AT THE INTERSECTION, SO I WENT TO THE LEFT OF THE CAR TO AVOID REAR ENDING HIM. I CONTINUED ACROSS THE INTERSECTION TOWARD THE CAR ACROSS THE STREET HOPING TO BE ABLE TO FIT BETWEEN HIM AND A TELEPHONE POLE WITHOUT HITTING EITHER TO LAND IN A SNOW BANK. I MANAGED TO HIT HIS FRONT END ON THE PASSENGER SIDE OF HIS CAR MISSING THE TELEPHONE POLE AND LANDING IN THE SNOW ABOVE THE CURB. NOBODY WAS INJURED, BUT HIS CAR AND MINE WERE DAMAGED. *TR

I WAS DRIVING ON A STRAIGHT, LEVEL DRY ROAD WITH CRUISE CONTROL SET AT 58MPH. SUDDENLY CAR BEGAN TO DOWNSHIFT. ASSUMING TRANSMISSION PROBLEM I DISENGAGED CRUISE CONTROL AND CAR ALMOST CAME TO A STOP. I PUSHED GAS PEDAL AND DROVE IN LOW GEAR TO NEAREST PULL-OFF. DISCOVERED LEFT FRONT BRAKE WAS SMOKING. AFTER THINGS COOLED OFF I DROVE CAR IN LOW GEAR ABOUT 6 MILES TO LOCAL SERVICE STATION. MECHANIC FOUND ALL BRAKES LOCKED AND REMOVED ALL WHEELS. HE INSPECTED ALL ROTORS, CALIPERS BRAKE LINES, ETC AND FOUND NO PROBLEMS. (I HAD NEW BRAKES INSTALLED AT DEALERSHIP ABOUT 4 MONTHS EARLIER.) WHEN MECHANIC MANIPULATED LEFT FRONT CALIPER ALL BRAKES DISENGAGED. MECHANIC FOUND BRAKE FLUID LEVEL WAS NORMAL. I'VE DRIVEN CAR ABOUT 500 MILES SINCE PROBLEM OCCURRED WITH NO PROBLEMS. I DON'T USE CRUISE CONTROL OFTEN - AND HAVEN'T USED IT SINCE PROBLEM OCCURRED. I'M WONDERING IF PROBLEM IS WITH CRUISE CONTROL RATHER THAN BRAKES?? THIS COULD HAVE BEEN A DISASTER IF IT HAPPENED ON A FREEWAY AT HIGHER SPEEDS! *TR

TL* THE CONTACT OWNS 2006 TOYOTA SIENNA. THE CONTACT STATED THAT WHILE DRIVING AT SPEEDS OF 50 MPH DOWN AN OFF RAMP, THE BRAKE WARNING LIGHT ILLUMINATED ON THE INSTRUMENT PANEL. THE BRAKES THEN ENGAGED WITHOUT DRIVER INTENT, RAPIDLY DECREASING THE VEHICLE SPEED FROM 50 MPH TO 20 MPH. THE DEALER ADVISED THERE WERE NO FAILURES WITHIN THE VEHICLE. THERE WERE NO REPAIRS MADE TO THE VEHICLE. THE FAILURE MILEAGE WAS 26,000 AND THE CURRENT MILEAGE WAS 27,000.

2006 TOYOTA SIENNA. CONSUMER STATES OSCILLATION PROBLEMS WITH VEHICLE. *TGW THE CONSUMER STATED HE WAS DRIVING DOWN FROM THE TOP OF A MOUNTAIN AND HE APPLIED THE BRAKES TO LIMIT HIS SPEED. THE RIGHT FRONT WHEEL WENT INTO A VIOLENT OSCILLATION AND HE WAS BARELY ABLE TO CONTROL THE VEHICLE. HE STOPPED BRAKING AND SHIFTED INTO A LOWER GEAR. HE APPLIED THE BRAKES AGAIN AND THE OSCILLATION RETURNED. WHEN HE REACHED THE BOTTOM OF THE HILL, THE OSCILLATION WENT AWAY. THE CONSUMER TOOK THE VEHICLE TO THE DEALER FOR AN INSPECTION. UPON, INSPECTION THE DEALER STATED THERE MAY HAVE BEEN A PROBLEM WITH THE ABS, BUT THEY COULD NOT VERIFY IT. ON DECEMBER 11, 2009 THE PROBLEM OCCURRED AGAIN. THE CONSUMER WAS DRIVING NORTH DOWN A GRAPEVINE INCLINE, WHEN THE RIGHT FRONT WHEEL STARTED TO OSCILLATE. THE CONSUMER IMMEDIATELY DOWN SHIFTED AS HE WAS MUCH MORE PREPARED. THE PROBLEM OCCURRED AGAIN ON FEBRUARY 13, 2010 WHILE DRIVING ON A FLAT SECTION OF A HIGHWAY. HE APPLIED THE BRAKES AND BOTH WHEELS STARTED TO OSCILLATE. *JB

I HAVE BRAKING FAILURE IN MY 2006 TOYOTA SIENNA LIMITED AWD VEHICLE. I HAVE TAKEN THE VEHICLE TO MY MECHANICS WHO HAS BEEN UNABLE TO PROPERLY DIAGNOSE THE PROBLEM. THERE ARE MANY REPORTS OF THIS PROBLEM ON THE INTERNET AND TOYOTA WILL NOT DISCLOSE THE RESOLUTION TO THIS COMMONLY REPORTED PROBLEM WITHOUT CHARGING A $89.99 DIAGNOSTICS CHARGE. THE REPAIR IS REPORTEDLY $1,200 TO $2,000 TOFIX THIS PROBLEM. I BELIEVE THIS IS A SAFETY ISSUE THAT SHOULD BE RECALLED. *TR

TOYOTA SIENNA 2006 BRAKING PROBLEM CAUSED SELF COLLISION. ON DRY WEATHER. VEHICLE LOST BRAKING AND I HIT NEAR BY HILLY LAND ON TURN. VEHICLE SHOWED BRAKING PROBLEM ON WET WEATHER, RAIN AND SNOW AND VEHICLE LOOSES THE BRAKING AND RELATED ABS AND VSC FAILURE. BRAKE PEDAL GOES DOWN AND CLICKS AND BRAKE STOPS WORKING. MY WIFE NO LONGER TRUST THIS VAN AND EVERYBODY IS AFRAID TO DRIVE WITH ME IN IT. *TR

COUPLE THINGS HAPPENED- RIGHT AFTER WE BOTH SIENNA, ABOUT 1 MONTH LATER THE BRAKE LIGHT WENT ON. IT WAS LATE SUNDAY NIGHT, SO THE DEALERSHIP WAS CLOSED. WE WENT THERE THE FOLLOWING WEEK. THEY COULDN'T FIND A PROBLEM, CAUSE THE LIGHT WENT OFF. WHEN I LEFT THE DEALER, THE LIGHT WENT BACK ON SO I LEFT MY CAR THEREAND TOLD THEM I'M NOT GOING TO DRIVE UNTIL THEY FIND A PROBLEM. I HAVE 2 SMALL KIDS AND THEIR SAFETY IS FIRST. THEY FIX IT AND SAID THAT SOME SENSOR UNFORTUNATELY WAS DAMAGED DURING THE DELIVERY AND THEY REPLACE IT. THEN I GOT PROBLEM WITH MY POWER SIDE DOOR- WILL STILL BE CLOSING EVEN IF YOU TRY TO STOP IT. SOLUTION FROM THE DEALER- LUBRICATE AND THAT'S IT- IT STILL HAPPEN FROM TIME TO TIME. NEXT- FRONT PASSENGER AND SECOND ROW SEAT BELTS- LOCK DURING THE TRIP. DEALER SOLUTION- THEY DON'T SEE THE PROBLEM. NOW ABOUT 2 MONTHS AGO MY ACCELERATOR GOT SUCK WHILE DRIVING FOR ABOUT 15 SECONDS. I DID NOT MADE A BIG DEAL OUT OF IT, BECAUSE I WAS SURE IT SUPPOSE TO HAPPEN, BUT NW AFTER HEARING WHAT GOING ON WITH OTHER TOYOTA MODELS, I'M JUST NOT SURE. THE GAS PEDAL DID NOT GOT STUCK TO THE CARPET FOR SURE- I WOULD SEE IT, IT WAS LIKE IT GOT STUCK AT 70MPH... I LOVE MY SIENNA AND HUSBAND DRIVES COROLLA TOO AND WE BOTH LOVE TOYOTAS. I JUST THINK NOW IT'S NOT ABOUT LOVE FOR THE ENGINE, IT'S ABOUT SAFETY OF OUR CHILDREN. IF NECESSARY I HAVE DOCUMENTS REGARDING THE BRAKE SENSOR REPLACEMENT, SEAT BELTS COMPLAINS, ETC. I SPOKE WITH THE DEALER ABOUT THE GAS PEDAL AND SAID TO ME THAT MY MODEL ITS NOT IN THE RECALL AND IT COULD BE SOMETHING ELSE, BUT DID NOT OFFER TO CHECK WHAT COULD IT BE... *TR

FAULTY BRAKE MECHANISM. TOYOTA SIENNA LIMITED 2WD WITH DISC BRAKES FRONT AND BACK. WHEN STOPPED BRAKES MUST BE CONTINUALLY DEPRESSED FURTHER AS TIME GOES ON TO KEEP VEHICLE FROM MOVING FORWARD. ALSO LOSES BRAKING POWER ON DOWNHILL. *TR

I WAS DRIVING DOWN A STREET APPROACHING A 4 WAY STOP. THERE WAS A CAR A GOOD DISTANCE AHEAD OF ME. WHEN I APPLIED THE BRAKES TO STOP, NOTHING HAPPENED.. I PICKED MY FOOT UP AND PUSHED ON THE BRAKE PEDAL AGAIN, STILL GOING FASTER. NOW I AM GETTING PRETTY CLOSE TO THE OTHER CAR WHICH IS STOPPING FOR THE STOP SIGN. I PUSHED HARD AS I COULD ON THE BRAKE (I'M SURE IT WAS THE BRAKE, I PICKED MY FOOT UP AND PUT IT BACK ON THE BRAKE PEDAL AT LEAST 2 OR 3 TIMES) SO I SWERVED TO THE LEFT TO AVOID THE CAR. BY NOW I AM GOING PRETTY FAST. THERE WERE CARS COMING THE OTHER WAY, SO I TRIED TO TURN THE CORNER TO AVOID HITTING THEM, WAS GOING TOO FAST TO MAKE THE CORNER, SO WOUND UP HITTING A CONCRETE WALL. I AM VERY SORE, CHEST, RIGHT HAND, LEFT KNEE. LOTS OF BRUISES, LUCKILY NO BROKEN BONES THAT I KNOW OF. I AM NOT SURE ABOUT THE AIR BAG. THE POLICE ASKED ME IF IT DEPLOYED, I LOOKED DOWN AT THE STEERING COLUMN AND SAW IT THERE, DEFLATED AND WITH A RIP IN IT, BUT I DON'T REMEMBER BEING ACTUALLY HIT WITH IT, HOWEVER I DON'T REMEMBER HITTING MY HAND OR KNEE EITHER,BUT OBVIOUSLY I DID. I HEARD ONE OF THE POLICEMEN SAY I MISTAKENLY HIT THE GAS INSTEAD OF THE BRAKE, BUT THAT IS JUST NOT TRUE. I KNOW I WAS ON THE BRAKE. THE CAR IS TOTALED, SO NO REPAIRS. *TR

RE: SAFETY PROBLEM WITH 2006 TOYOTA SIENNA XLE, OUR SIENNA IS NOT SAFE. ON NUMEROUS OCCASIONS THE WHEELS WERE SPINNING WHEN WE TRIED TO DRIVE AFTER STOPPING AT THE STOP SIGN, AT TRAFFIC LIGHTS, OR IN THE MIDDLE OF THE INTERSECTION. IT IS A VERY DANGEROUS MALFUNCTION, BECAUSE IT PREVENTS THE DRIVER FROM MERGING INTO OR ESCAPING FROM HEAVY TRAFFIC OF NORTHERN VIRGINIA. IT HAPPENED IN ALL KINDS OF WEATHER AND ROAD SURFACE CONDITIONS. I AM A VERY CAREFUL DRIVER; I SPEND A LOT OF TIME DRIVING MY THREE YOUNG CHILDREN. I NEVER HAD AN ACCIDENT AND I NEVER HAD A PROBLEM WITH THE SPINNING TIRES ON ANY OTHER CAR I HAVE DRIVEN. WE CONTACTED OUR DEALERSHIP AND TOYOTA COMPANY. THEIR FIRST RESPONSE WAS THAT IT IS NOT THEIR PROBLEM. AFTER OUR INTERVENTION THE DEALERSHIP AGREED TO DRIVE TEST OUR CAR. THE TEST WAS PERFORMED BY ONE OF THE EMPLOYEES (NOT CLEAR IF HE HAD ANY CAR SAFETY INSPECTION TRAINING). HE TOOK OUR CAR FOR A SHORT DRIVE AROUND THE NEIGHBORHOOD, ALONE, IN THE PERFECT WEATHER, REPORTING BACK THAT HE DID NOT NOTICE ANY PROBLEM. THE TEST DRIVE WAS A COMPLETE WASTE OF TIME. WE HAVE PROBLEMS WITH THE CAR USUALLY WHEN THERE IS MORE THAN ONE PERSON IN THE CAR, DURING THE RAIN ETC; IN OTHER WORDS, IN AVERAGE DRIVING CONDITIONS. SINCE THE TEST WE HAD THE SAME PROBLEM AGAIN, MANY TIMES. I BELIEVE WE ARE NOT THE ONLY OWNERS OF SIENNA, WHO HAVE THE SAME PROBLEM. I OBSERVED IT SEVERAL TIMES ON THE STREET, WITH OTHER SIENNAS. ALSO, MY INFORMAL POLL AMONG OUR FRIENDS GAVE THE SAME RESULTS. *TR

PREMATURE WEARING OF BOTH FRONT BRAKES AND TIRES (BOTH NEEDED TO BE REPLACED BY 15,000 MILES). *TR

BRAKES WEAR OUT EXTREMELY QUICK. REPLACED THE BRAKES AT 1 YEAR WITH 17,000 MILES AND NOW AGAIN TODAY AT 2 YEARS AND 30,000 MILES. I DRIVE MOSTLY ON THE FREEWAY WITHOUT ANY QUICK OR ABRUPT STOPS. THERE SEEMS TO BE A PROBLEM WITH THE BRAKE SYSTEM. *TR

FRONT BRAKE PADS WORE OUT VERY FAST. FRONT BRAKES MAKE NOISE, 3 TIMES FIXED UNDER WARANTY AND 4TH TIME BEING FIXED AT DEALERSHIP UNDER WARANTY. I THINK SOME PROBLEM WITH BRAKE SYSTEM DESIGN AND FUNCTION. *TR

TL*THE CONTACT OWNS A 2006 TOYOTA SIENNA. WHILE DRIVING DOWNHILL AT VARIOUS SPEEDS, THE CONTACT HAS TO APPLY THE BRAKES. THE TRANSMISSION DOWNSHIFTS AND FAILS TO RESHIFT INTO THE CORRECT GEAR. THE DEALER STATED THAT THE ELECTRONIC CONTROL WAS THE FAILURE. THE CURRENT MILEAGE WAS 31,000 AND FAILURE MILEAGE WAS 21,000. UPDATED 03/06/08. *LJ THE CONSUMER WAS NOT INFORMED THE VEHICLE HAD POWER ASSIST BRAKES. THE CONSUMER STATED WHEN HE SLAMMED ON THE BRAKES, A MORE POWERFUL BRAKING WOULD BE APPLIED. AT THAT POINT, THE CONSUMER WOULD HEAR A SOUND IN THE ENGINE COMPARTMENT AND FEEL VIBRATIONS OF THE BRAKE PEDAL.

TL*THE CONTACT OWNS A 2006 TOYOTA SIENNA. WHILE DRIVING 60 MPH, THE CONTACT DEPRESSED THE BRAKE PEDAL, BUT THE VEHICLE FAILED TO STOP. THE UNDERCARRIAGE OF THE VEHICLE DRAGGED ON THE GROUND, WHICH CAUSED THE VEHICLE TO STOP. THE DRIVER SUSTAINED INJURIES TO HIS KNEE, LEFT ANKLE, NECK, AND BACK. THE VEHICLE WAS DESTROYED AND HAS NOT BEEN INSPECTED. THE VIN AND ENGINE SIZE WERE UNAVAILABLE. THE CURRENT AND FAILURE MILEAGES WERE 8,000.

BRAKES: SINCE I BOUGHT MY CAR IN MARCH OF 2006 NOT EVEN A YEAR OLD YET, I HAVE HAD TO TAKE MY 2006 TOYOTA SIENNA IN EVERY 7-8 THOUSAND MILES BECAUSE THE BRAKES HAVE WORN DOWN. THE FIRST TIME IT WENT IN AT 9900 MILES AND THEY REPLACED MY BRAKES AND PUT NEW ROTORS ON. THE SECOND TIME THEY PUT NEW BRAKES ON AND MACHINED MY ROTORS THIS WAS DONE AT 18,100 MILES AND NOW ITS AT 27,100 MILES AND MY BRAKES ARE SHOT AGAIN AND THE DEALER KNOWING THAT THIS IS MY THIRD TIME IN FOR SAME PROBLEM TOLD ME NOW ALL OF A SUDDEN THAT ITS MY FAULT AND THE WAY I DRIVE THE VAN, AND THEY WANTED ME TO PAY THIS TIME FOR THE REPAIRS. THEY MADE THEIR DIAGNOSIS ONLY BY TAKING OFF THE TIRES, THEY NEVER TOOK OFF THE FRONT BRAKES TO INSPECT THEM AND YET THEY HAD NERVE TO NOTATE THAT ALL PADS WERE WEARING EVENLY, . SO I DROVE HOME AND A LICENSED TECH CHANGED MY BRAKES FOR LESSER PRICE AND THIS TECH NOTED THAT ALL PADS ON FRONT WORE UNEVENLY AND THAT MY ROTORS WERE FINE WHERE AS THE DEALER WANTED ME TO BUY NEW ROTORS BECAUSE THEY SAID THEY WERE RUINED. THE TECH THAT FIXED MY CAR KEPT THE SAME ROTORS AND JUST PUT NEW BRAKES ON FOR HALF THE COST THE DEALER WANTED ME TO PAY. YET THIS DEALER IN HEMET CALIFORNIA AT GOSCH AUTO GROUP WOULD NOT REPLACE MY BRAKES THE ONES THEY PUT ON LAST TIME 7 THOUSAND MILES BEFORE THIS TIME UNLESS I PAID FOR THEM. THERE IS OBVIOUSLY SOMETHING WRONG WITH THE BRAKE LINE SYSTEM WHICH IS CAUSING THEM TO GO OUT EVERY 7-8 THOUSAND MILES. THIS IS A SAFETY ISSUE AND ME AND MY 4 KIDS COULD GET SERIOUSLY INJURED SHOULD THIS BRAKE PROBLEM CONTINUE MAYBE I MIGHT NOT BE SO LUCKY AND MY BRAKES WILL FAIL. THESE BRAKES SUCK AND SO DOES THIS CAR AS MY HUSBAND SAID I SHOULD HAVE GONE WITH A CHEVY. *JB

2005 TOYOTA SIENNA AWD. REAR DISC BRAKES...CLIP RUST CAUSES THE CALIPER PISTON TO STAY EXTENDED AND KEEP THE DISC BRAKE PAD IN CONTACT WITH THE DISC. BRAKES WEAR EXCESSIVELY... BRAKES NEEDED TO BE REPLACED IN 23000 MILES WITH WEAR ON THE DISC. DEALER STATES THIS IS COMMON PROBLEM. CLIP REPLACED WITH NEW CLIP AT CUSTOMER REQUEST, DISC RESURFACED. BOTH AT CUSTOMER EXPENSE. SERVICE PERSON STATES THEY ARE GETTING SEVERE RUST ON THESE CLIPS, COULD CAUSE BRAKE FAILURE. *NM
