2005 Toyota Sienna Brakes Problems

I was driving on dry road at approximately 65mph. There was a very slight curve in the road and the ABS system engaged without warning resulting in the van power immediately decreasing and fishtailing. Fortunately there was no one immediately behind or beside me or it would have resulted in a collision. I am afraid to use the vehicle. Used a code reader and there are no stored codes.

ABS PUMP STOPPED WORKING. NO WARNING. BRAKES FAILED,RAN INTO MY GARAGE. TOOK TO LOCAL MECHANIC. HAD TO PUMP BREAKS TO GET IT THERE OR PAY TOWING COST. LEARNED OVER 2000.00 FOR THE PART. IT IS KNOW TO GO OUT HE SAID AND SHOUOD GAVE BEEN A RECALLED ITEM...

ABS BRAKE PUMP MODULE. WENT OUT CAUSING ACCIDENT. NO WARNING. ABS LIGHTS CAME ON. TOOK TO SHOP. DRAINING BATTERY,CAUSING BRAKES TO FAIL. SHOUOD BE RECALLED DUE TO NO WARNING,COMPLETE BRAKE FAILURE,CAUSING VEHICLE TO BE DANGEROUS, NOT ROAD WORTHY.

PARKING BREAK DOES NOT ENGAGE UNTIL AFTER SEVERAL TRIES OF ENGAGEMENT. AND MANY TIMES DOES NOT ENGAGE AT ALL. GRADE LOCATION OF THE VEHICLE DOES NOT MATTER (E.G. HORIZONTAL TO >% DEG). ATTEMPTS ARE ONLY MADE WHILE VEHICLE IS IN PARK. (IT IS NOT ATTEMPTED WHILE VEHICLE IS IN DRIVE, REVERSE OR NEUTRAL)

SINCE 7/2019 TO NOW, 10/2019, I'VE HAD INTERMITTENT HARD BRAKE PEDAL. LETTING UP ON THE GAS PEDAL, THE VAN BEGINS TO STOP RIGHT AWAY. THERE'S NO RHYME OR REASON FOR THE HARD BRAKE PEDAL, ITS AFFECTING THE FRONT RIGHT WHEEL, AND IT SMELLS BAD. THERE'S A VIBRATION AT TIMES, AND WOBBLE. AFTER THE VAN SITS FOR AN HOUR, THE BRAKES ARE FINE UNTIL NEXT TIME. TODAY, BACKING OUT OF A PARKING SPOT, IT WAS DIFFICULT TO PUT THE VAN IN REVERSE, AND LETTING OFF THE BRAKE, THE VAN WOULDN'T ROLL BACK. I HAD TO GIVE IT QUITE A BIT OF GAS TO GET IT TO MOVE. THE VAN DIDN'T WANT TO GO MORE THAN 10MPH IN A 35MPH ZONE. ALL OF THIS HAS HAPPENED SINCE A NEW BRAKE BOOSTER WAS INSTALLED. THERE IS A NEW CALIPER ON THAT RIGHT SIDE, AND BOTH FRONT BRAKES GOT NEW BRAKE LINES. THE PADS STILL HAVE A LOT OF MEAT ON THEM. I CAN DRIVE THE VAN JUST FINE, THEN SOMETIMES GET BACK IN THE VAN LATER, 1 TO 6 HOURS LATER, AND THE BRAKE PEDAL IS HARD. IT OCCURS WHEN THE VAN HAS BEEN SITTING ALL NIGHT AND HALF THE NEXT DAY, OR IT CAN HAPPEN WHEN I'M DRIVING IT. THERE IS SOMETHING WRONG WITH THE BRAKES ON MY 2005 SIENNA. NOBODY CAN FIGURE IT OUT.

WHILE DRIVING AT 55 MPH HIGHWAY SPEED AND CURVING GENTLY TO THE RIGHT, THE VSC SYSTEM ON THIS MINIVAN EVIDENTLY PICKED UP A FALSE INDICATION OF A SLIP IN THE VEHICLE'S TRACTION. THIS CAUSED THE CAR TO AUTOMATICALLY APPLY THE BRAKES ON THE LEFT SIDE, PULLING THE VAN'S DIRECTION FROM RIGHT TO LEFT, AND SLOW THE CAR QUICKLY FROM 55 TO 35 MPH, WITH VEHICLES BEHIND ME QUICKLY CLOSING IN ON THE REAR END. WITHIN SECONDS THE AUTOMATIC BRAKING CEASED AND I WAS ABLE TO REACCELERATE BACK TO NORMAL HIGHWAY DRIVING SPEED. THE ENGINE WAS NOT STALLED IN THE PROCESS.

ABS LIGHTS ACTIVATE GOING AT SPEEDS FROM 15-60 ON ANY TYPE OF CURVES THEN STARTS BRAKING AUTOMATICALLY. THIS SITUATION HAS BEEN GOING ON FOR A WHILE AND AS LATE AS THIS PAST WEEKEND (10 TIMES) ON HIGHWAY 299 WEST FROM REDDING,CA. - EUREKA, CA. THESE SENSORS NEED TO BE RECALLED.

TL* THE CONTACT OWNS A 2005 TOYOTA SIENNA. THE CONTACT STATED THAT WHEN THE VEHICLE WAS SHIFTED INTO REVERSE, THE BRAKE PEDAL WAS DEPRESSED BUT FAILED WITHOUT WARNING. THE VEHICLE ROLLED INTO THESTREET. THE CONTACT HAD TO CONTINUOUSLY PUMP THE BRAKE PEDAL IN ORDER TO STOP THE VEHICLE. THE VEHICLE WAS NOT DIAGNOSED NOR REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 105,000.

TL* THE CONTACT OWNS A 2005 TOYOTA SIENNA. WHILE DRIVING VARIOUS SPEEDS, THE ABS SEIZED INTERMITTENTLY AND THE ABS WARNING INDICATOR ILLUMINATED ONCE DURING THE FOURTEEN TIMES THE ABS FAILED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE BRAKE ACTUATOR FAILED AND WOULD NEED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURES. THE APPROXIMATE FAILURE MILEAGE WAS 135,000.

2005 SIENNA ANTI SKID ACTIVATES WITHOUT PROVOCATION, SIMILAR TO MANY OTHER COMPLAINTS, SKID VSC COMES ON FOR NO REASON, PUTTING ON BRAKES UNCONTROLLABLY. HAPPENED ON FREEWAY IN RAIN AND ALMOST LOST CONTROL. SEE THE WEBSITES AND DEALER COMPLAINTS. SOMEONE IS GOING TO GET KILLED HERE. DO SOMETHING! INTERMITTENT AND VERY DANGEROUS CAN CAUSE OUT OF CONTROL SKIDDING AND HAPPENS WITHOUT WARNING IN WET OR DRY CONDITIONS

IT JUST TURN ON ANTI-LOCK BRAKE SYSTEM AND BRAKE LIGHTS. TOYOTA TOLD ME THAT THE ACTUATOR IS DAMAGED, REPLACEMENT COST $ 1,900.00. SAFETY ISSUE

TL* THE CONTACT OWNS A 2005 TOYOTA SIENNA. DURING COLD WEATHER, THE REAR BRAKES FAILED TO ENGAGE. THE CONTACT HAD THE REAR BRAKES REPLACED, BUT THE FAILURE RECURRED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 88,000.

APPROACHING FULL STOP REALIZED THAT ALTHOUGH BRAKING CAR WAS NOT SLOWING. BRAKE AGAIN AND AGAIN THEN CAR FELT AS IF COASTING IN FREE FALL THEN SHOT FORWARD LIKE AN AIR PLANE TAKING OFF. KEPT SLAMMING ON BRAKE; SUDDENLY CAR STOPPED MOVING FORWARD - NO HUGE JERK/LURCH AS ONE MIGHT EXPECT FROM SUDDEN STOP JUST......STOPPED. CONTINUED TO DRIVE HOME. A FEW TIMES I PRESSED ACCELERATOR AND THEN BRAKE TO COMPARE TO "EVENT" AND AM CONVINCED I WAS BRAKING THE ENTIRE TIME OF THE "EVENT". I AM TRAINED MOVEMENT SPECIALIST AND KNOW MY FOOT WAS ON BRAKE NOT ACCELERATOR. TOWED CAR TO DEALER TODAY. TOYOTA CAN'T FIND ANYTHING WRONG WITH CAR AND SUGGESTED I HAD BEEN STEPPING ON ACCELERATOR. *TR

2005 TOYOTA SIENNA. CONSUMER WRITES IN REGARDS TO BRAKE FAILURE. *SMD THE CONSUMER STATED SEVERAL WEEKS AGO, HE WAS TURNING AROUND IN THE DRIVEWAY, AND WHEN HE PRESSED DOWN WITH HIS RIGHT FOOT, THE ENGINE ROARED AND THE VEHICLE JUMPED FORWARD UNTIL HE APPLIED MORE PRESSURE TO THE BRAKE PEDAL, AT WHICH POINT THE VEHICLE STOPPED. THE CONSUMER REALIZED THE BRAKE PEDAL COULD BE DEPRESSED EASILY BELOW THE LEVEL OF THE GAS PEDAL, HENCE THE ROAR AND SURGE. THE CONSUMER WAS INFORMED BRAKE PEDALS WERE NO LONGER ADJUSTABLE AND WHEN THE MECHANIC CHECKED THE VEHICLE, THE BRAKE MASTER CYLINDER WAS FAILING AND ACCOUNTED FOR THE BRAKES NOT FUNCTIONING PROPERLY AT TIMES.

TL* THE CONTACT OWNS A 2005 TOYOTA SIENNA. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 30 MPH, THE TRACTION CONTROL WARNING INDICATOR ILLUMINATED WITH A CHIME.

THE APPROXIMATE FAILURE MILEAGE WAS 100,000.

I WAS DRIVING IN TRAFFIC AND BRIEFLY LOOKED TO SIDE OF ROAD. THEN LOOKED BACK AND NOTICED TRAFFIC STOPPED AHEAD OF ME. FULLY APPLIED BRAKES (HARD) BUT NO BRAKING, SQUEALING OR ABS. FULL AIRBAGS BUT FORTUNATELY NO INJURIES. LOOKING AT THE SCENE I SHOULD HAVE HAD PLENTY OF DISTANCE TO STOP. CAR TOTALED. *TR

2005 TOYOTA SIENNA BRAKE FAILURES. THIS SEEMS TO BE AN INTERMITTENT PROBLEM - STEP ON BRAKE PEDAL - CAR DOES NOT STOP. BRAKES HAVE BEEN CHANGED AND REINSPECTED. A SEARCH ON THE WEB SHOWS THAT THIS IS A KNOWN PROBLEM AND MANY COMPLAINTS HAVE BEEN FILED REGARDING THIS ISSUE. *TR

MY WIFE WAS DRIVING OUR 2005 TOYOTA SIENNA VAN TO PICK UP OUR SON FROM SCHOOL. AS SHE WAS PULLING INTO A PARKING SPACE, SHE PUSHED ON THE BRAKES TO SLOW DOWN FURTHER. HOWEVER, THE VAN DID NOT SLOW DOWN, BUT INSTEAD ACCELERATED, CAUSING THE VAN TO HIT A TREE AT THE END OF THE PARKING SPACE AND THE CAR ON THE OTHER SIDE OF THE TREE. SHE CONFIRMED THAT SHE ONLY HIT THE BRAKES, AND NOT THE ACCELERATOR. AFTER READING MULTIPLE ONLINE REPORTS OF OTHERS PUSHING ON THE BRAKES AND THE TOYOTA SIENNA VANS ACCELERATING, I DECIDED TO FILE THIS REPORT. *TR

I HAVE AN INTERMITTENT FAILURE WITH THE ANTI-SKID. ONCE OR TWICE A MONTH I WILL BE TURNING WITHOUT ANY BRAKES ON AND THE ANTI-SKID LIGHT COMES ON AND THE CAR BEHAVES LIKE IT IS TRYING TO COMPENSATE FOR A SKID. *TR

BRAKE FAILURE IN A 2005 TOYOTA SIENNA. I SEE OTHER REPORTS OF THIS PROBLEM IN SIENNAS BASED ON AN ON-LINE GOOGLE SEARCH. THE PROBLEM, IN MY CASE, IS INTERMITTENT. BRAKE FAILURE HAS HAPPENED TWO TIMES WHEN ATTEMPTING TO STOP AT INTERSECTIONS. ONCE TO MY WIFE AND ONCE TO ME. THE PEDAL DOES NOT GO ALL THE WAY DOWN TO THE FLOOR, BUT PRESSING HARD ON THE PEDAL IS INEFFECTIVE TO STOP THE CAR IN A NORMAL DISTANCE. THE ABS SYSTEM DOES NOT ENGAGE DESPITE THE AMOUNT OF STRONG FORCE ON THE PEDAL THAT I EXERTED. THE CAR EVENTUALLY CAME TO A STOP, BUT IT FEELS AS THOUGH THERE IS NO VACUUM ASSIST. PUMPING THE BRAKE DID NOT HELP. THE PAVEMENT WAS NOT SLICK. THE BRAKES APPEAR TO WORK NORMALLY AT OTHER TIMES. *TR
