2004 TOYOTA SIENNA Vehicle Speed Control Problems

Vehicle often applies brakes on its own . At first it was only in turns . However now it does it when driving straight on the the freeway or just down the street at 45mph. I have fixed my alignment ,new tires, all of the front suspension and nothing prevents the car from trying to brake for me. it is a safety feature that is not safe at all. a car slamming on your brakes at any speed is dangerous in addition to that it seems to cut off your fuel , leaving you unable to accelerate until its done beeping which can take a long time. the vsc , chenk engine and trac off flash there is no crash to report I have been lucky so far

Was driving on highway at 60-65 mph. The car continued to accelerate. Pressed on brake and wasn't slowing the vehicle. The driver was weaving in and out of cars as the van started to creek up to 92 mph. The driver and passengers thought they were going to crash and possible die. The driver tried the brake multiple times and nothing. The driver said the accelerator pedal wasn't pressed all the way down to the floor. It was half way and driver had to go down and pull up on the pedal while driving. The van then started to slow and driver was able to pull over to have the van evaluated . The throttle body was reached and cleaned of carbon because it said that this may have been part of the issue. Never has this van taken off like this. The throttle body cable wasnt loose or disconnected either. So far we havent been able to recreate but 3 people could have been killed.

The contact owns a 2004 Toyota Sienna. The contact stated that while driving approximately 65 MPH the vehicle suddenly experienced unintended acceleration and the speed of the vehicle increased to over 90 MPH. During the failure, the braking system had failed and would not stop the vehicle while pressing the brake pedal. The front passenger was able to view the fuel pedal was stuck to the floor and was able to physically pull the fuel pedal up from the stuck position and the vehicle's speed was reduced. The incident lasted for approximately 10 minutes. During the incident, the police were on the scene. A police report was later filed at the scene and the vehicle was towed to the local dealer. The contact was informed by the dealer that the failure was due to a missing fuel pedal pen. No further information was available. The manufacturer was notified of the failure. The contact expressed experiencing emotional stress and anxiety during and after the incident. The manufacturer was notified of the failure. The failure mileage was 200,000. The VIN was not available.

The trac control is activated while the car is driving variable speed and brake the car and and the driver loose control of acceleration.

- Traction control engaged at high speed(70 mph on interstate) causing the vehicle to brake abruptly and pull the vehicle to the right. Had I been traveling in the left hand lane, I could have been forced into the right hand lane causing a collusion with another vehicle. Also occurred at lower speed(30 mph on a windy road) causing the same issue as described above, almost causing the vehicle to leave the paved surface. - Mechanic was able to duplicate the issue - Mechanic diagnosed intermittent traction control activation, scanned computer for codes. Yaw rate/steering angle correlation causing false activation ABS/traction. Replaced hub bearing and spindle. Four wheel alignment, including check castor, camber and adjust toe. Performed zero point calibration and reset ABS memory. - Traction control lights up briefly

About a year ago the Vehicle Stability Control warning light along with an audible alarm started coming on intermittently while turning on highways going uphill or downhill in dry weather and with no risk of any tire slipping. At first this only happened at higher speeds 65+mph. Over time, it has occurred more and more frequently and can occur at speeds down to 25 mph. At times, the Anti-lock Braking System is also activated resulting in jerky braking and loss of throttle. When people have been following me too closely, this has almost caused accidents. When these symptoms occur, it is always on a curve (of any degree, even slight curves) and while driving at least 25 mph, and even happens on flat turns now. The weather has always been dry with no risk of tire slippage.

Sometimes when I take turns in my Sienna, the VSC starts going off and braking individual wheels without my control. This happens unexpectedly on highway bends at speeds of 60+ mph and it is difficult to control the car and keep from swerving into another lane. If the roads were icy when this happens, it would probably cause a dangerous accident. Toyota has a technical service bulletin for this, but not a recall - which it should since this is a significant safety issue. The TSB is BR008-04. There are many others experiencing this same issue: https://forums.edmunds.com/discussion/13855/toyota/sienna/vsc-sudden-activation-2004-toyota-sienna

I had the control arms replaced, then one of the bolts came out after a few thousand miles. I had that bolt replaced and the problem started happening intermittently after that. Everything will be functioning fine and then the speed of my vehicle is inhibited and it is hard to accelerate. It is very difficult to get from 40 MPH up to 50 MPH. On slight curves, not always, it will beep and the slip indicator light comes on and will apply the brakes on what feels like one side. This has happened at 35-60 MPH. The slip indicator will beep sometimes until I decrease my speed to under 25 MPH. I took it into a reputable tire and front end shop and they replaced a wheel bearing with sensor, and 2 front tires. The problem happened again within 5 miles and the shop said I need to take it to Toyota dealer to have it the steering angle sensors recalibrated. The Toyota dealership said that this is something that the vehicle does itself. They inspected it and took it for a test drive and said nothing is wrong. The problem happened again within a few miles of leaving the dealership. I have read countless forums of people experiencing the same thing in their Toyota Sienna and having the dealership telling them there is not a problem. I have also found that the solution could very well be worn rack and pinion bushings that are creating the play that are triggering the sensors. I don't think they gave it a proper inspection. This is a very dangerous problem, and even more so when the dealership is saying there isn't a problem. I am feeling very lost on what to do with my van right now. I have spent $1100 and 3 days of my time with the same thing happening. I

WHEN DRIVING UNDER NORMAL CONDITIONS THE VEHICLES' VSC WILL ENGAGE. THE DASHBOARD LIGHTS GO OFF, THERE IS A LOUD INTERIOR BEEPING SOUND, THE ABS ENGAGES, THE CAR SLOWS DOWN DRASTICALLY AT ONCE. THE ROADS ARE DRY. AT FIRST THIS HAPPENED WHILE DRIVING NORMAL SPEED EXITING OR ENTERING AN HWY OFF/ON RAMP. THEN HAPPENED YESTERDAY AS I WAS DRIVING ON NEIGHBORHOOD STREETS AT ABOUT 25-30 MPH. I COULD HEAR A RUBBING ON THE BACK TIRES AS IF THE BRAKES WERE ON.

TRACTION CONTROL KICKS IN FOR NO REASON, TRATION BEEPING AND TIRES LOCK,AT FREWAY SPEED TRACTION CONTROL ACTIVATES AND CUTS OFF SPEED DRAMATICALLY.VERY UNSAFE TO DRIVE.

WHILE DRIVING AT 55 MPH OR FASTER, GENERALLY ON A RIGHT HAND BEND, THE VSC WILL ACTIVATE PULSING THE BRAKE AND VIOLENTLY PULLING THE CAR TO THE LEFT AND TOWARDS ONCOMING TRAFFIC. THE SKID LIGHT GOES ON, AND THE CAR BEEPS UNTIL YOU ARE OUT OF THE TURN AND THEN IT GOES AWAY. THIS PROBLEM HAS BEEN INTERMITTENT FOR ABOUT 6 MONTHS BUT HAS GOTTEN MUCH WORSE AND MORE FREQUENT IN THE PREVIOUS 2 MONTHS. IT HAS BEEN TO THE DEALERSHIP SEVERAL TIMES AND THEY DO NOT KNOW WHAT TO DO. THERE ARE NO ERROR CODES. THE BEST THEY CAN SAY IS "YOU'RE GOING TO FAST..." WHICH IS A WHOLLY UNACCEPTABLE ANSWER CONSIDERING WE ARE GOING THE SPEED OF TRAFFIC AND NO MORE THAN 0-10 OVER THE SPEED LIMIT. *TR

NHTSA RECALL NUMBER 13V429, MFR RECALL NUMBER D0R IS LISTED ON THE SAFECAR.GOV WEB SITE FOR MY VIN NUMBER AS BEING AN INCOMPLETE RECALL, BUT THE TOYOTA SERVCO SERVICE CENTER SAYS THEY HAVE ALREADY FIXED THIS RECALL ON MY CAR. I HAD AN INCIDENT RECENTLY THAT WAS TRACED TO THE GEAR SHIFT CABLE BUSHING. THE CAR WAS PARKED IN A GROCERY STORE PARKING LOT, PUT INTO PARK, IGNITION TURNED OFF, AND THEN STARTED TO ROLL BACKWARD, THE BRAKE DIDN'T WORK TO STOP THE ROLLING SINCE THE IGNITION WAS OFF, LUCKILY THE PARKING BRAKE WAS APPLIED TO STOP THE ROLLING BEFORE ANY DAMAGE WAS DONE, IT WAS A VERY GRADUAL SLOPE. I SEE THAT THE LATER 2014 MODEL SIENNA HAS A RECALL FOR THE GEAR SHIFT CABLE, BUT MY YEAR DOES NOT HAVE A RECALL FOR THIS PROBLEM SO I HAD TO PAY ~ $600 TO GET THIS FIXED. LUCKILY NO ONE WAS HURT AND NO PROPERTY WAS DAMAGED.

ON NUMEROUS OCCASIONS, WE HAVE HAD THE VSC INDICATOR LIGHT TURN ON WHILE DRIVING ON DRY PAVEMENT WHILE ON THE HIGHWAY, WHICH CAUSED THE CAR TO APPLY THE BRAKES AND ALSO SWERVE. OUR CAR IS AWD SO THE FIRST TIME IT HAPPENED, WE THOUGHT THERE MUST HAVE BEEN BLACK ICE ON THE ROAD (EVEN THOUGH THE ROAD APPEARED DRY). IT FIRST HAPPENED ABOUT THREE YEARS AGO, ALTHOUGH IT IS HAPPENING MORE FREQUENTLY NOW. WE DROVE HOME YESTERDAY THROUGH THE MOUNTAINS AND IT HAPPENED FOUR TIMES ON OUR TWO HOUR DRIVE. IT MOSTLY HAPPENS WHILE GOING DOWNHILL FOR US, AND HAS HAPPENED AT SPEEDS OF 70 MPH - 30 MPH. IT HAS HAPPENED WHILE TURNING (BOTH DIRECTIONS) AND GOING STRAIGHT. IT IS VERY SCARY FOR BOTH MY WIFE AND I, AND I FEEL UNSAFE WITH HER DRIVING OUR CAR WITH OUR FOUR CHILDREN. WE'VE TAKEN IT TO THE DEALERSHIP AND THEY WANT TO CHARGE US LOTS OF MONEY TO TRY TO FIX WHAT THEY "THINK" THE PROBLEM IS. I HAVE SPOKEN WITH OTHER SIENNA OWNERS WHO HAVE EXPERIENCED THE SAME FRIGHTENING EXPERIENCE SO KNOW IT IS NOT JUST OUR CAR, DRIVING, ETC.

TL* THE CONTACT OWNS A 2004 TOYOTA SIENNA. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, THE VEHICLE STABILITY CONTROL WARNING LIGHT AND TRAC WARNING LIGHT ILLUMINATED INTERMITTENTLY. AS A RESULT, THE VEHICLE DECELERATED INDEPENDENTLY. THE FAILURE RECURRED NUMEROUS TIMES. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE STEERING SENSOR NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED HOWEVER, THE FAILURE PERSISTED. THE VEHICLE WAS TAKEN BACK TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE CABLE NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED BUT THE FAILURE PERSISTED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 70,000.

IT STARTED A YEAR OR SO AGO THE WHILE DRIVING ON DRY ROAD ABOVE 50MILES THE VSC LIGHT WOULD LIT WITH A ALARM SOUND, THE VAN WILL AUTOMATICALLY APPLY BRAKES AND SLOW THE SIENNA. SINCE THIS WAS EXTRA VAN AND WE WERE DRIVING MOSTLY SEDANS WE HAD AND DUE TO BUSINESS I COULD NOT SPEND ANY TIME ON IT.. NOW IT HAPPENS MORE FREQUENTLY AND IT RISK OUR LIFES ON HIGHWAY. UPON SEARCHING INTERNET VARIOUS FORUMS CAME WITH WITH PROBLEMS PERTAINING ONLY TO THIS YEAR AND MODEL, PLEASE SEARCH (SUDDEN VSC ACTIVATION) AND YOU WILL FIND MULTIPLE OWNER ONLY OF 2004 COMPLAINING FOR SAME ISSUE.. IN FACT THERE ARE TO TWO TSB ARTICLES TO POINT TO THIS PROBLEM ( TSB-BR001-04 AND TSB-BR004-03) . I WOULD KINDLY REQUEST TO INVESTIGATE THE SUDDEN VSC ACTIVATION IN MIDDLE OF HIGHWAY. I HAVE SPENT MONEY TO REPLACE TIRES, ALIGMENT BALANCING TO FIND THE ISSUE IS WIDESPREAD.

AT VARYING RATES OF SPEED, ON DRY ROADS, MY VAN'S VSC AND TRACTION CONTROL ICONS WILL ILLUMINATE ON THE DASH, THE ACCELERATION WILL CEASE AND THE BRAKES WILL PUMP 2-4 TIMES, AND THE STEERING WILL STICK. ORIGINALLY, THIS OCCURRED ONLY ON ROADS THAT CURVED HOWEVER THE FREQUENCY OF OCCURRENCE IS INCREASING AND IT NOW OCCURS ON STRAIGHT ROADS AS WELL. *TR

PURCHASED 2004 SIENNA XLE AWD LIMITED 2/18/15. WHILE COMMUTING TO WORK THE TRACTION CONTROL SYSTEM RANDOMLY ACTIVATES IN DRY CONDITIONS (USUALLY ON DOWNHILL ANGLED TURN) CAUSING LOSS OF POWER, ACTIVATION OF FRONT RIGHT BRAKES, AND THE STEERING WHEEL JERKED FROM MY HANDS (RESULTING IN TRANSIENT OVERALL LOSS OF CONTROL OF VEHICLE). THIS DEFECT HAS OCCURRED 6 TIMES IN 2 DAYS AND I AM CURRENTLY AFRAID TO DRIVE THE CAR, ESPECIALLY WITH A 3 MONTH OLD. THERE HAVE BEEN MULTIPLE REPORTS ON EDMUNDS.COM AND OTHER TOYOTA FORUMS THAT SUPPORT THIS IS AN ONGOING PROBLEM WITH THIS MODEL/YEAR VEHICLE. THIS IS A SAFETY DEFECT AND THE VEHICLE SHOULD BE RECALLED TO PREVENT INJURY OR FATALITY AND TO RESOLVE THE ISSUE WITH THE TCS. THERE IS NO WAY TO TURN OFF THE TCS MANUALLY AND THIS ISSUE CAN CAUSE AN ACCIDENT. *TR

THE OUTSIDE TEMPERATURE WAS BELOW 32 AND IT WAS CLOSE TO 25 OR SO. WHEN I WAS DRIVING THE CAR AT 40 MPH WITH ENGINE TEMP STILL SLIGHTLY ABOVE COLD(NOT AT OPTIMAL WHICH IS ALMOST HALF WAY) AND SLOWED DOWN BY USING GENTLE BRAKES(NOT HARD BRAKES). JUST BEFORE THE VEHICLE COMES TO A FULL STOP, THERE IS UNINTENDED ACCELERATION AND I COULD SEE EVEN THE RPM(SCALE) TO SPIKE TEMPORARILY. THIS HAS BEEN HAPPENING EVERY TIME WHEN OUTSIDE TEMP IS COLD AND VEHICLE IS DRIVEN WITH COLD OR SLIGHTLY ABOVE COLD ENGINE TEMPERATURE. THERE IS A RISK OF HITTING ANOTHER VEHICLE OR MEETING ACCIDENT IF MISJUDGE MY BRAKING BECAUSE OF THIS PROBLEM.. PLEASE NOTE : THIS PROBLEM DISAPPEARS WHEN ENGINE TEMPERATE IS AT OPTIMAL AND I HAVE DRIVING A HONDA ACCORD 2008 EXL FOR LAST 7 YEARS(WAS BOUGHT NEW ONE), I NEVER HAD EXPERIENCED THIS PROBLEM IN THAT CAR EVEN WHEN DRIVEN WITH COLD ENGINE. *TR

DASH BOARD HAS A CRACK ON PASSENGER SIDE RIGHT WHERE THE AIR BAG IS. WHILE DRIVING ON THE FREEWAY NOTICED CHECK ENGINE LIGHT CAME ON AND SPEEDOMETER READING WENT TO 0. STOPPED COUNTING MILES AND CAR GOING ON 65 BUT SPEEDOMETER READS 0. ALSO GAS TANK LEVEL INDICATOR GOES FROM HALF TANK TO EMPTY AND GAS LIGHT TURN ON. IT IS NOT SAFE AS I DON'T KNOW AT WHAT SPEED MY CAR IS GOING ON AND ALSO IF THE CRACK ON THE DASH BOARD GETS BIGGER, AIR BAGS MIGHT POP OUT. NEED SOMEBODY TO LOOK INTO THIS AS THE VAN IS DRIVEN ONLY 49000 MILES. THIS IS VERY UNUSUAL . *TR

SUDDEN DECELERATION OF VEHICLE: 2004 TOYOTA SIENNA XLE. THE VSC ENGAGES, WITHOUT WARNING, ON SMOOTH, DRY ROADS AND WHEN CORNERING OR NEGOTIATING A CURVE. WE ARE THE ORIGINAL OWNERS AND HAVE NEVER EXPERIENCED THIS UNTIL THE FIRST INCIDENT IN LATE OCT. 2014. WE DID NOT TAKE ANY ACTION BECAUSE ALTHOUGH ROAD CONDITIONS GOOD, WE WERE ROUNDING A SHARP BEND IN THE ROAD AND ASSUMED THIS HAD SOMETHING TO DO WITH THE INCIDENT. VEHICLE SPEED WAS APPROXIMATELY 25 MPH AS THE VEHICLE SUDDENLY DECELERATED, THE VSC LIGHT CAME ON AND A RAPID BEEPING ALARM SOUNDED. THE VEHICLE PULLED TO ONE SIDE AND STEERING THE VEHICLE BECAME EXTREMELY DIFFICULT. THE WHOLE INCIDENT, START TO FINISH, LASTED APPROXIMATELY 5 SECONDS. THE NEXT INCIDENT HAPPENED IN EARLY DECEMBER 2014. AGAIN, ALL THE ABOVE DESCRIBED THINGS HAPPENED, EXCEPT VEHICLE SPEED WAS APPROXIMATELY 35 MPH GOING AROUND A GENTLE CURVE IN THE ROAD. I DID SOME RESEARCH AND FOUND MANY COMPLAINTS CONCERNING THIS ISSUE BUT DO NOT SEE ANY RECOMMENDATIONS OR RECALLS OFFICIALLY ISSUED BY TOYOTA. IT APPEARS MOST OF THE DEALER RECOMMENDED REPAIRS DID NOT CORRECT THE PROBLEM. TODAY (DECEMBER 26, 2014), THIS SAME ISSUE HAPPENED FIVE TIMES WITHIN 40 MINUTES. MY WIFE MANAGED TO GET THE VEHICLE HOME AND WE CALLED OUR LOCAL TOYOTA DEALER, DESCRIBED THE ISSUE AND THEY INFORMED US THEY HAVE NEVER RECEIVED ANY COMPLAINTS CONCERNING RAPID DECELERATION OF THIS MODEL YEAR, BEFORE OUR PHONE CALL. I'VE SCHEDULED AN APPOINTMENT FOR DECEMBER 30, 2014 TO HAVE THE VEHICLE CHECKED OUT AND HAVE RECALL WORK DONE CONCERNING THE "SHIFT LOCK SOLENOID ASSEMBLY". WILL UPDATE AFTER APPOINTMENT. *TR

IN THIS INITIAL INCIDENT, I WAS TRAVELING ON A CURVY ROAD AT POSTED SPEED LIMIT OF 30MPH. MY VEHICLE SUDDENLY SLOWED, AS IF I WAS APPLYING THE BRAKES, WHICH I WAS NOT, AND MY STEERING WAS COMPROMISED. IN ADDITION THE VSC INDICATOR AND SYMBOL FLASHED ON MY DASHED AND BEEPED. THE ROAD WAS DRY. THIS HAS OCCURRED 10+ TIMES SINCE. I HAVE BROUGHT IT TO MY MECHANIC, WITHOUT TURNING THE ENGINE OFF AFTER THE OCCURRENCE SO THAT HE COULD "READ" THE COMPUTER BUT THERE IS NO EVIDENCE AVAILABLE. WE HAVE BROUGHT IT TO THE TOYOTA DEALER. THEY "REBOOTED" THE SENSORS AND SAID IT SHOULD BE FINE. IT HAS CONTINUED TO HAPPEN, ON THE FREEWAY GOING UPHILL AT 55 MPH, GOING DOWNHILL AT 60 MPH AND HAS BEEN CLOSE TO CAUSING A REAR END COLLISION EACH TIME. *TR

STARTING FROM A STOP AND ACCELERATING UP TO APPROX 20 MPH, ABS TRACS VSC LIGHTS ILLUMINATED WITH BEEPING ALERT, AND ACTIVATION OF BRAKES CAUSING A SUDDEN DECELERATION. THE ROAD WAS DRY, LEVEL PAVEMENT, NO ICE, NO GRAVEL, DRIVING STRAIGHT AND THE BRAKES WERE NOT BEING APPLIED. THERE WERE NO CONDITIONS THAT WOULD NECESSITATE THE TRACTION CONTROL. AS THE BRAKES WERE NOT BEING APPLIED AT THE TIME OF THE INCIDENT, THE REAR BRAKE LIGHTS WOULD NOT HAVE ILLUMINATED. THEREFORE, ANY DRIVER BEHIND OUR VEHICLE WOULD NOT HAVE BEEN ALERTED TO THE SUDDEN DECELERATION WHICH COULD HAVE RESULTED IN A COLLISION. FORTUNATELY THIS WAS NOT THE CASE. THIS IS THE 2ND TIME THAT THIS ISSUE HAS OCCURRED WITH THIS VEHICLE. THE FIRST WAS IN NOV. 2007 (46000 MILES IN THE VEHICLE). TOYOTA SERVICE WAS NOT ABLE TO FIND A FAULT, NO CODES STORED AND NOT ABLE TO REPLICATE AT THAT TIME. THEY SAID THAT THEY WOULD HAVE A CORPORATE CONTACT GET IN TOUCH WITH ME. I NEVER HEARD FROM THEM. NOTHING WAS RESOLVED. THERE ARE AT LEAST TWO TSBS RELATED TO THE VSC ISSUE (TSB BR004-03 AND BR008-04). NEITHER WAS IMPLEMENTED. *TR

I ATTEMPTED TO MERGE ONTO THE EXPRESSWAY AND AFTER PUSHING THE GAS PEDAL THE VAN SUDDENLY ACCELERATED BEYOND MY CONTROL. I EASED OFF THE PEDAL AND THE VAN CONTINUED TO SERGE AHEAD WITH NO WAY FOR ME TO STOP OR SLOW IT DOWN AS THE BRAKES WOULD NOT WORK. I SAW THE RPM REACH LEVEL 6 AND SPEED INCREASE TO 70 IN SECONDS BUT AS IT WAS THE EXPRESSWAY, I WAS ABLE TO KEEP MY DISTANCE FROM CARS IN FRONT OF ME. I SWITCHED THE LEVER TO THE NEUTRAL POSITION AND THE VAN SLOWED DOWN AND THEN I WENT BACK TO DRIVE AND IT ROARED BACK UP TO 70 MPH WITH THE RPM AGAIN AT 6 AND I TRIED TURNING THE CRUISE CONTROL ON AND THEN BRAKING TO SEE IF IT WOULD SHUT DOWN THE GAS BUT NO LUCK. I WENT BACK AND FORTH FROM D TO N FOR ABOUT 2 MINUTES AND THEN ON ONE OF THE MOVEMENTS FROM N TO D IT SHUT DOWN BACK TO NORMAL. I DROPPED THE VAN OFF AT MY TOYOTA DEALER THE NEXT DAY AND AM WAITING TO SEE WHAT "HEADQUARTERS " DECIDES. *TR

MY CAR IS A 2004 TOYOTA SIENNA AWD XLE LIMITED. THE VEHICLE WILL ACTIVATE THE VEHICLE SKID CONTROL (VSC) WITHOUT WARNING WHILE DRIVING ON SMOOTH DRY ROADS. THE EFFECT IS FOR THE VEHICLE TO APPLY BRAKES STRONGLY TO SPECIFIC WHEELS PULLING THE CAR STRONGLY TO ONE SIDE. THIS HAPPENS MOST FREQUENTLY WHILE DRIVING WINDING ROADS AND IN CORNERS. IT HAS BECOME MORE REGULAR IT IT'S OCCURRENCE AND HAS HAPPENED ON RELATIVELY STRAIGHT SECTIONS OF HIGHWAY MOST RECENTLY. A SIMILAR SITUATION OCCURRED APPROX 2 YEARS AGO. AT THAT TIME THE RETAILER REPAIRED IT BY ADJUSTING THE STEERING SENSOR USED BY THE VSC AND STATED THAT THIS SHOULD BE DONE PERIODICALLY DEPENDENT ON ALIGNMENT WORK DONE ON THE VEHICLE. THIS SOLVED THE ISSUE AT THAT TIME. IT IS VERY DANGEROUS BOTH TO THE VEHICLE WHICH REQUIRES GREAT EFFORT TO MAINTAIN CONTROL AND THE VEHICLES FOLLOWING IT WHICH ARE AT RISK OF REAR ENDING THE EFFECTED CAR. THE TOYOTA RETAILER INITIALLY INDICATED THAT A CATALYST FAILURE WAS THE CAUSE (YES THEY SAID THIS). I WAS TOLD THAT THE CAT FAILURE COULD INDUCE OTHER BRAKE AND ENGINE RELATED FAILURES. THE CAT WAS REPLACED AND THE VSC FAILURE HAS RESUMED. AT THIS TIME NO FAILURES OF ANY KIND ARE INDICATED. I HAVE RESEARCHED THIS TOPIC AND FIND ABOUT A DOZEN IDENTICAL FAILURES ON 2014 TOYOTA SIENNAS DOCUMENTED IN VARIOUS USER FORUMS. AS THERE ARE ONLY A FEW DOCUMENTED ON THE NHTSA SITE I AM CONCERNED THAT THE SITUATION IS UNDER REPORTED. MANY OF THESE USER FORUMS INDICATE THAT THE SYMPTOMS WERE REPORTED TO THE MANUFACTURER. MY MOST RECENT TROUBLE REPORT CASE NUMBER FROM TOYOTA IS [XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

DRIVING MY 2004 TOYOTA SIENNA 65MPH ON THE HIGHWAY ON DRY PAVEMENT THE VSC LIGHT WENT ON, A BUZZER SOUNDED, AND I WAS UNABLE TO STEER OR BRAKE THE VEHICLE. THE STEERING WHEEL STARTED MOVING RAPIDLY RIGHT AND LEFT CAUSING THE CAR TO FISHTAIL AND THE BRAKE PEDAL WENT GOING IN AND OUT ON ITS OWN. EVERYTHING WENT BACK TO NORMAL AFTER ABOUT 20 SECONDS OR SO, AND I PULLED OFF INTO THE BREAKDOWN LANE. I THEN PULLED OUT AGAIN SLOWLY TO GET MY CAR IN A SAFER AREA AND IT HAPPENED AGAIN. THIS TIME I WAS GOING MUCH SLOWER BUT IT WAS HORRIFYING NONE THE LESS. I THEN PULLED OFF THE ROAD AND HAD THE CAR TOWED TO THE TOYOTA DEALER. I FOUND THAT A TECHNICAL SERVICE BULLETIN HAD BEEN ISSUED ON MY CAR IN 2005 AND THAT THE STEERING ANGLE SENSOR WAS THE CULPRIT. THE BULLETIN SAYS THAT "SOME CUSTOMERS MAY EXPERIENCE AN INTERMITTENT VSC ACTIVATION." OWNERS OF THE 2004 SIENNA HAVE NOT BEEN NOTIFIED OF THIS PROBLEM, WHICH AFTER EXPERIENCING IS CLEARLY A SAFETY ISSUE, AND THERE SHOULD HAVE BEEN A RECALL RATHER THAN A TSB. THE TSB SEEMS CLEVERLY WORDED TO AVOID THE FACT THAT A DRIVER COULD LOOSE ALL CONTROL OF THE STEERING WHEEL AND BRAKES WHICH IS CLEARLY A SAFETY ISSUE. *TR

2004 TOYOTA SIENNA VAN, THE VEHICLE STABILITY CONTROL SYSTEM (VSC) GOES INTO SKID PREVENTION MODE AND AUTOMATICALLY APPLIES THE BRAKES, DISCONNECTS THE ACCELERATOR, AND SELECTS ONE SIDE OR WHEEL TO APPLY BRAKING FORCE TO. THIS HAS THE EFFECT OF CAUSING THE CAR TO SHUDDER, SKID AND MOVE DANGEROUSLY CLOSE TO THE OUTSIDE EDGE OF A CURVE. THIS HAS OCCURRED 15-20 TIMES IN MY CAR SINCE ITS PURCHASE. I HAVE TAKEN IT FOR REPAIR BY THE DEALER THREE TIMES. SOME "RUSTED" PARTS WERE REPLACED THE FIRST TIME. THE NEXT TWO TIMES, I WAS TOLD THE VEHICLE WAS WORKING PROPERLY.

THE PROBLEM IS INTERMITTENT AS I HAVE DRIVEN OVER THE SAME ROADS AT THE SAME OR HIGHER SPEEDS FOR YEARS WITHOUT ACTIVATION OF THE VSC. WHEN IT DOES ACTIVATE IT IS FRIGHTENING, AND IT CAUSES A SIGNIFICANT DANGER OF LOSING CONTROL OF THE CAR OR VEERING OUT OF YOUR LANE. AFTER A PERIOD OF NO ACTIVITY, I HAVE SUDDENLY HAD 7 INCIDENTS IN THE LAST WEEK OCCURRING BETWEEN DEC. 24, 2010 AND JANUARY 2, 2011.THE PROBLEM FIRST AROSE APPROXIMATELY THREE YEARS AGO.

I HAVE A 2004 TOYOTA SIENNA, IT IS NOT RECALLED. MY TOYOTA VAN WOULD STRUGGLE TO GET MOVING ESPECIALLY GOING UP A SMALL INCLINE I WOULD HAVE TO PUSH THE GAS PEDAL TO THE FLOOR(THE CARS RPMS WOULD RACE) IN ORDER FOR IT TO MOVE, IT WAS LIKE GASPING FOR AIR. I BROUGHT IT TO TOYOTA AND THEY RAN THE TESTS AND SAID NOTHING WAS WRONG, IN THE END THEY CLAIMED IT WAS THE FLOOR MAT PREVENTING THE GAS PEDDLE FROM OPERATING PROPERLY. NOT POSSIBLE THE FLOOR MAT WAS NOT OUT OF PLACE BECAUSE OF STAINS ON THE FLOOR. THE FLOOR MAT IS HEAVY AND DOES NOT SLIDE AROUND. NOW I AM FRUSTRATED SO BROUGHT IT TO COTTMANS AUTOMOTIVE AND THEY RAN THE COMPUTER ON IT AND SAID NOTHING CAME UP ON THE COMPUTER AS NOT WORKING, IF IT KEEPS DOING IT BRING IT BACK. WELL NOW I KNOW WHETHER IT COMES OUT OR NOT THIS IS A COMPUTER PROBLEM. IT DOES NOT SHOW UP ON THE COMPUTER TESTS THEY RUN AND YOU CAN NOT DUPLICATE THE PROBLEM ON DEMAND. WITH ALL THE TROUBLES OCCURRING WITH TOYOTA, THEY ARE TRYING TO BLAME IT ALL ON FLOOR MATS, A COMPUTER PROBLEM WOULD BE MUCH MORE COSTLY TO REPAIR SOMETIMES COMPUTERS CAN TAKE CONTROL. I FIND IT VERY INTERESTING MY PROBLEM AND NOW THE PROBLEM WITH ACCELERATION IS ALL BLAMED ON FLOOR MATS?

I OWN A 2004 TOYOTA SIENNA. I PURCHASED IT AUG, 2009 AND 2 WEEKS LATER WHILE FLOORING THE ACCELERATOR, THE ENGINE ACCELERATED THE VEHICLE SPONTANEOUSLY AFTER PULLING MY FOOT OFF THE PEDAL. I FRANTICALLY STOMPED ON THE PEDAL AND APPROXIMATELY 3 SECONDS PASSED UNTIL THE ENGINE DECREASED R.P.M. ADMITTEDLY I HAD JUST PREVIOUSLY PLACED AN "AFTER MARKET" FLOOR MAT IN THE DRIVER COMPARTMENT AND REMOVED IT IMMEDIATELY WHEN REACHING MY DESTINATION. HOWEVER, THIS FLOOR MAT AND THE ORIGINAL ONE WERE NOWHERE NEAR THE GAS PEDAL. I CAN ONLY EXPLAIN THE REASON WHY I NEVER REPORTED THIS UNTIL NOW AS: I REALLY DON'T EVER HAVE TO "FLOOR" THE ACCELERATOR ANYWAY. IN LIGHT OF THE ONGOING EXPOSURE IN THE MEDIA OF THESE TYPES OF PROBLEMS WITH TOYOTAS. I AM COMPELLED TO VOICE MY EXPERIENCE IN HOPES THAT THIS MAY AVOID HARM AND EVEN SAVE LIVES. MY TOYOTA CURRENTLY IS NOT INCLUDED IN A RECALL RELATED TO THIS ISSUE, EVEN THOUGH OTHER REPORTS ARE ALREADY PUBLISHED IN THE MEDIA SIMILAR TO MY EXPERIENCE WITH THE SIENNA. PERSONALLY, I BELIEVE THAT THE FLOOR MAT RECALL WAS A HOAX, AND THE CLAIM THAT THE GAS PEDAL SENSOR, MADE BY A U.S. FIRM, BEING AT FAULT IS JUST A DELIBERATE DISTRACTION TO THE COSTLY TRUTH. I BELIEVE TOYOTA HAS ELECTRONIC, AND PROBABLY EVEN COMPUTER RELATED PROBLEMS WITH IT'S VEHICLES, AND IF ALL OF THIS DUE PROCESS GOES AS IT SHOULD, MY PREDICTION IS THIS: ALL TOYOTAS WITH "DRIVE BY WIRE" SYSTEMS WILL BE RECALLED, AND IT WILL INVOLVE MORE THAN JUST PEDAL SENSORS AND FLOOR MATS. SERIOUSLY, PEOPLE ARE IN JAIL BECAUSE TOYOTAS HAVE ACCELERATED OUT OF CONTROL, BUT WHAT CONCERNS ME THE MOST IS THAT I HAVE A WIFE AND FOUR CHILDREN THAT I LOVE MORE THAN CAN BE DESCRIBED, THAT DEPEND ON THIS TOYOTA TO FUNCTION SAFELY FOR US ON A DAILY BASES.

IN MAY OF 2008, I WAS ATTEMPTING TO PULL MY 2004 TOYOTA SIENNA INTO THE GARAGE. I WAS IDLING WHEN SUDDENLY THE VEHICLE TOOK OFF. I WAS STANDING WITH BOTH FEET ON THE BRAKE AND COULD NOT STOP. I CRASHED THROUGH THE REAR OF THE GARAGE AND HIT A TREE WHICH RIPPED THE RIGHT TIRE AND AXLE FROM THE DRIVE SHAFT. AT THAT POINT, I CAN TO A STOP HOWEVER THE ENGINE CONTINUED TO RACE UNTIL I TURNED OFF THE VEHICLE. MY 2 YEAR OLD DAUGHTER HAD BEEN RIGHT OUTSIDE THE BACK DOOR OF THE GARAGE WHEN I CRASHED THROUGH. SHE WAS SOMEHOW PUSHED OFF TO THE SIDE. THE BACK PORTION OF THE WALL AND THE BACK DOOR WENT ABOUT 30 FEET INTO THE BACKYARD. THE TREE I HIT WAS ABOUT 45 FEET BEHIND THE GARAGE. I TRAVELED FOR ANOTHER 50 FEET AFTER HITTING THE TREE AND LOSING MY RIGHT FRONT TIRE. WHEN WE HAD THE VEHICLE LOOKED AT BY THE TOYOTA DEALERSHIP IN SIOUX CITY, IA, THEY SAID NOTHING WAS WRONG WITH THE VEHICLE. SINCE IT HAS BEEN REPAIRED, THE ELECTRONIC SPEED CONTROL WILL QUIT WORKING AT TIMES AND THERE ARE ERROR LIGHTS THAT SHOW UP ON THE DASHBOARD. I BELIEVE IT IS AN ESC LIGHT AND THE CHECK ENGINE LIGHT THAT SHOW UP WHEN THE SPEED CONTROL QUITS WORKING. ONCE THESE LIGHTS GO AWAY, THE SPEED CONTROL WILL CONTINUE WORKING AGAIN. *TR

OUR FAMILY PURCHASED A BRAND NEW 2004 TOYOTA SIENNA AWD AND HAD COUNTLESS ISSUES WITH IT . THE MOST SERIOUS ISSUE WAS - RANDOM UNPREDICTABLE ACCELERATION RESPONSES. WE CONTACTED TOYOTA CANADA & JAPAN IN 2003. THERE IS ABSOLUTELY 100% NO DOUBT IN MY MIND, OR MY WIFE'S MIND, THAT THE TOYOTA PRODUCT LINE HAS SOMETHING WRONG ELECTRONICALLY IN THEIR ACCELERATOR PEDAL OR TRANSMISSION SENSORS - OR THE SOFTWARE THAT INTERFACES WITH THEM. WE DID NOT HAVE STICKY GAS PEDALS OR FLOOR MAT ISSUES - WE HAD A VEHICLE THAT DIDN'T OPERATE THE WAY WE WERE ASKING IT TO. THE VEHICLE NEVER CONSISTENTLY RESPONDED TO THE ACTUAL PRESSURE BEING PLACED ON THE ACCELERATOR PEDAL. A LIGHT PRESS IN PARKING LOT DRIVING WOULD SOMETIMES RESULT IN WHAT FELT LIKE FULL THROTTLE ACCELERATION AND WHEN TRYING TO TURN ACROSS TRAFFIC AT AN INTERSECTION, OR DURING MERGING - THE VEHICLE WOULD HESITATE AND THEN MOVE THE VEHICLE WHEN IT WAS NO LONGER SAFE TO DO SO.. TOYOTA SAID " THEY DID NOT CONSIDER THIS BEHAVIOR A SAFETY ISSUE " IT WAS ONLY " A NUISANCE PROBLEM " . FIRST OUR DEALERSHIP IGNORED THE PROBLEM. THEN THEY SAID " MY WIFE DIDN'T TEACH THE VEHICLE TO DRIVE PROPERLY - IT HAD A SMART LEARNING TRANSMISSION YOU KNOW " . THEY FINALLY ADMITTED THERE WAS A PROBLEM AFTER WE CONTINUED TO VOICE OUR CONCERN OVER SEVERAL NEAR MISS INCIDENTS WITH THE VEHICLE . IN ONE INCIDENCE , WHILE ON THE HIGHWAY USING CRUISE CONTROL - THE VEHICLE UNEXPECTEDLY ACCELERATED FULL THROTTLE INTO A CORNER AT OVER 140 KPH FORCING US ONTO THE SHOULDER AND ALMOST OFF THE ROAD . IT WAS A NERVE SHATTERING EXPERIENCE. OUR TOYOTA DEALER FINALLY ADMITTED A SIMILAR ACCELERATION PROBLEM EXISTED IN THE CAMRY / COROLLA LINES AND THAT IT WAS TRANSMISSION SOFTWARE RELATED . AFTER SEVERAL MONTHS OF THE RUN AROUND FROM TOYOTA WITH NO FIX IN SIGHT - BEING TOLD BY THE OWNER OF THE DEALERSHIP TO DRIVE THE VEHICLE IN 3RD GEAR TO MINIMIZE THE SURGES UNTIL A SOFTWARE FIX WAS CREATED - WE WALKED AWAY FROM THE VEHICLE. *TR

THE SPEED CAN BE ACCELERATED TO OVER 5 MILES/HR MORE THAN THE CRUISE CONTROL SETTING. FOR EXAMPLE, WHEN I SET THE SPEED TO 70 MILES/HR, AT A LITTLE LONGER UPHILL ROAD, THE SPEED WILL DROP FIRST (LIKE 67MILES/HR) AND THEN ACCELERATE IN ORDER TO GET BACK TO 70MILES/HR SPEED TARGET. BUT THE CRUISE CONTROL SYSTEM CONTINUE ACCELERATING AFTER PASSING 70 MILES/HR AND COULD BE AS HIGH AS 75MILES/HR. 3. NOTHING HAD BEEN DONE, JUST BE CAUTIOUS BY MYSELF.

2004 TOYOTA SIENNA XLE LIMITED- UNCONTROLLED CRUISE CONTROL ACCELERATION/DECELERATION. THE PROBLEM HAS CONTINUOUSLY OCCURRED SINCE PURCHASE IN SEPTEMBER 2004. DEALERSHIP DENIES PROBLEMS. DYNAMIC CRUISE CONTROLSYSTEM CAUSES MY CAR TO DANGEROUSLY ACCELERATE AND DECELERATE. WHEN LASER DETECTS NEARBY VEHICLE, THE CAR WILL BRAKE ABRUPTLY. LIKEWISE, ONCE THE NEARBY CAR IS NO LONGER IN LASER RANGE, THE CAR WILL ACCELERATE ABRUPTLY TO RETURN TO THE SET CRUISE CONTROL SPEED. I HAVE ALMOST BEEN HIT FROM BEHIND MULTIPLE TIMES ON FREEWAYS BECAUSE OF THE ABRUPT DECELERATION. I HAVE BEEN CAUGHT OFF GUARD SEVERAL TIMES BY THE ACCELERATION AND NEARLY LOST CONTROL OF THE VEHICLE.

I HAVE NEVER DRIVEN A CAR WITH SUCH A DANGEROUS CRUISE CONTROL SYSTEM. I NO LONGER USE MY CRUISE CONTROL SYSTEM BECAUSE I FEAR THAT I'LL BE UNABLE TO DISENGAGE THE SYSTEM AND LOSE CONTROL OF THE VEHICLE. *TR

I HAD A SUDDEN ACCELERATION EXPERIENCE IN A 2004 TOYOTA SIENNA VAN. I AM FILING THIS COMPLAINT BECAUSE I AM CONCERNED THAT THE RECENTLY ANNOUNCED TOYOTA RECALLS DO NOT INCLUDE THE SIENNA MODEL. THE INCIDENT OCCURRED WHILE I WAS PARKING MY ROOMMATE'S SIENNA VAN. I PULLED INTO A PARKING SPOT. UNHAPPY WITH THE ANGLE IN WHICH I WAS PARKED, I PUT THE VEHICLE INTO REVERSE, BACKED UP SLOWLY THEN PUT THE VEHICLE INTO DRIVE AND STARTED TO EASE INTO THE PARKING SPOT WHILE STRAIGHTENING THE WHEEL. AS THE VEHICLE MOVED FORWARD, THE ENGINE SUDDENLY MADE A LOUD ROARING NOISE AND LEAPT FORWARD OUT OF CONTROL, JUMPING A PARKING CURB AND UP OVER THE SIDEWALK IN FRONT OF THE RESTAURANT. I PLACED BOTH FEET IMMEDIATELY ON THE BRAKE BUT COULDN'T STOP THE VEHICLE. WHAT STOPPED THE VEHICLE WAS THE BRICK WALL OF THE RESTAURANT. AFTER THE INCIDENT, WE HAD THE VEHICLE EXAMINED BY A TOYOTA DEALER WHO DID DIAGNOSTIC TESTING AND COULD NOT DETERMINE A CAUSE FOR THE SUDDEN ACCELERATION. THIS EVENT OCCURRED PRIOR TO NEWS REPORTS OF A POSSIBLE PROBLEM WITH TOYOTA VEHICLES. WHEN THE TOYOTA PROBLEM BECAME PUBLIC LAST FALL, I CONTACTED TOYOTA AND OFFICIALLY "REGISTERED" MY EXPERIENCE WITH THE SIENNA VAN (TOYOTA REFERENCE #0911107062). I ALSO CALLED MY TOYOTA DEALER IN MY TOWN (MACOMB IL) WHO ADMITTED THERE WAS ANOTHER SIENNA VAN BROUGHT TO HIM THAT ALSO EXPERIENCED A SUDDEN ACCELERATION AFTER THE ONE I WAS DRIVING. MY STATE FARM INSURANCE AGENT IS ALSO AWARE OF THAT OTHER SIENNA EXPERIENCE. I AM NOT SEEKING REIMBURSEMENT BUT I AM CONCERNED THAT THE SIENNA MODEL SHOULD ALSO BE CONSIDERED FOR THE PEDAL ASSEMBLY RECALL. AT THE TIME, THIS SIENNA HAD APPROXIMATELY 78,000 MILES ON IT. JUST FOR THE RECORD, I AM A 2007 TOYOTA CAMRY OWNER AND HAVE NOT HAD ANY ISSUES WITH SUDDEN ACCELERATION IN THIS VEHICLE (APPROXIMATELY 22,000 MILES), THANK YOU. *TR

I HAVE A 2004 TOYOTA SIENNA. I WAS ONLY DRIVING AT 10 MPH OUT OF A PARKING LOT WHEN I REALIZED THE VSC WAS ACTIVATED EVEN THOUGH THE VEHICLE WAS NOT IN A SKID SITUATION OR ON A SLIPPERY PAVEMENT.

I HAVE 2004 AWD SIENNA. A WEEK AGO, WHEN I STARTED THE CAR IN A FREEZING MORNING AND DROVE IN SUBDIVISION ROAD, THE SLIPPERY LIGHT AND BEEP CAME ON AND THE BRAKE ACTED HERE AND THERE ON THE WHEELS. AT THE VERY BEGINNING, I THOUGHT THE ROAD WAS SLIPPERY. BUT IT WAS NOT THE CASE. THERE WAS NO WAY MY VAN WAS SKIDDING ALL THE TIME. I WAS ONLY DRIVING AT 10 MPH. THEN I REALIZED THE VSC WAS WRONGLY ACTIVATED. WHENEVER I GET TO MORE THAN 10MPH, VSC GOT ACTIVATED AND BROKE THE SPEED DOWN TO 5 MPH. I COULD ONLY DRIVE AT 5MPH WITHOUT GETTING VSC ACTIVATED. THEN I REALIZED I COULD NOT DRIVE THIS VAN ON THE ROAD. I PARKED IT BACK IN GARAGE. THE NEXT DAY, MY WIFE DROVE IT OUT OF THE GARAGE AND GOT THE SAME SYMPTOM. WE PUT THE VAN BACK TO GARAGE FOR ANOTHER 3 DAYS BEFORE I WAS ABOUT TO CALL A TOW TRUCK TO TOW IT TO A DEALER FOR EXAMINATION. I TRIED IT AGAIN. MIRACULOUSLY, THE PROBLEM WENT AWAY. I WENT TO THE DEALER AND TALKED TO THE SERVICE ADVISER, HE SAID HE KNEW NOTHING ABOUT THE PROBLEM (RECALL ETC.) AND ASKED ME TO BRING THE VAN BACK FOR SERVICE ONCE THE PROBLEM HAPPENS AGAIN. MY VAN APPEARS TO BE WORKING CORRECTLY NOW, BUT I DARE NOT DRIVE IT FAR AWAY FROM HOME. I KNOW THE PROBLEM IS NOT GONE. IT WILL COME BACK AT THE MOST INCONVENIENT TIME. I DO NOT WANT TO BE STRANDED IN A SNOW STORM AT -30 DEGREES F THAT I CAN ONLY DRIVE AT 5MPH (THAT IS WHAT THE WEATHER IS LIKE HERE IN CHICAGO AT THIS TIME OF THE YEAR). I DO NOT WANT TO BE THOUSAND MILES AWAY FROM HOME WHEN THE PROBLEM HAPPENS AGAIN. IT WOULD BE NIGHTMARE IF VSC WRONGLY COMES ON AT HIGH WAY SPEED. *TR

SUDDEN ACCELERATION IN 2004 TOYOTA SIENNA VAN: AT 0830AM PST, APRIL 29TH 2008 I WAS DRIVING TO WORK AT MY SCHOOL WHERE I WORK AS A TEACHER. WHILE MAKING A SLOW U-TURN, WITH MY FOOT LIGHTLY ON THE BRAKE PEDAL, MY 2004 TOYOTA SIENNA LE VAN SUDDENLY TOOK OFF AND ACCELERATED UNCONTROLLABLY LIKE A ROCKET AT MAXIMUM VELOCITY. THE ACCELERATOR PEDAL WAS NEVER PRESSED DURING THIS INCIDENT. I HAD JUST A SPLIT SECOND TO REMOVE MY FOOT COMPLETELY OFF THE BRAKE PEDAL TO LOOK DOWN AT THE FLOOR BOARD TO ENSURE NOTHING WAS PINNING THE PEDAL DOWNWARD, NOTHING WAS THERE AND THE VAN WAS STILL ACCELERATING LOOKED UP IN HORROR AS VEHICLE WAS CONTINUING TO ACCELERATE AT AN EXTREMELY HIGH RATE OF SPEED AND CONTINUING TO ACCELERATE. I QUICKLY STEERED THE VEHICLE AND DODGED A SCREENED CHAIN-LINK FENCE TO AVOID AN AREA WHERE CHILDREN USUALLY STAND WAITING FOR PARENTS. WITH VEHICLE STILL ACCELERATING AT FULL POWER I QUICKLY PASSED THE FENCE AREA, APPLIED THE BRAKES WITH GREAT FORCE, BUT THEY FELT UNRESPONSIVE TO THE ACCELERATION FORCES. WITH VEHICLE MOVING AT A VERY HIGH RATE OF SPEED AND STILL ACCELERATING, I SAW A PARKED VEHICLE RIGHT IN FRONT OF ME AND COULD NO LONGER CONTROL THE VEHICLE, I BRACED FOR IMPACT. THE VAN VIOLENTLY SMASHED INTO AN UNATTENDED FORD EXPEDITION VEHICLE, ENGINE BRIEFLY REVVED HIGH AND THEN FINALLY SHUT DOWN. HAD THERE NOT BEEN A PARKED VEHICLE THERE I WOULD HAVE GONE DIRECTLY INTO THE RESIDENTIAL HOUSE ABOUT 50 FEET AWAY. IT ONLY TOOK ABOUT 3 OR 4 SECONDS FOR THE VAN TO TRAVEL THE 22 YARDS FROM WHERE THE ACCELERATOR MALFUNCTION STARTED TO THE IMPACT AREA OF THE OTHER VEHICLE. THERE IS NO DOUBT THAT THIS SITUATION WILL OCCUR AGAIN TO SOMEONE ELSE. LIVES WILL BE LOST AND DRIVERS WILL BE FALSELY HELD ACCOUNTABLE. I STRONGLY RECOMMEND THAT THE NHSTA INVESTIGATE THIS SERIOUS ISSUE. I AM SO CONCERNED ABOUT THIS ISSUE THAT I AM SENDING A COMPLETE DISSERTATION TO ALL TV NETWORKS (20/20, ETC) HOPING THAT SOME AGENCY WILL EXPOSE THIS TO A HIGH LEVEL OF PUBLIC AWARENESS. *TR

AS I WAS DRIVING ON A DRY ROAD AT ABOUT 30 MPH THE VEHICLE SPEED CONTROL (VSC ) INDICATOR LIGHT WENT OFF, FOLLOWED BY A CONTINUOUS BEEPING FROM THE DASHBOARD, BY A VIBRATION OF THE VEHICLE (MORE THE LEFT SIDE) AND BY AN AUTOMATIC INTERMITTENT APPLICATION OF THE BRAKES ON SELECTED TIRES AS IF THE MINIVAN WAS TRYING TO REGAIN CONTROL AND PULLING TOWARDS THE LEFT. THE MINIVAN IMMEDIATELY SLOWED ITS SPEED TO LESS THAN 5 MPH AND WHEN TRIED TO REAPPLY FOR ACCELERATION, AS SOON AS EXCEEDED 5 MPH THE BEEPING RESTARTED, THE LIGHT WENT OFF AGAIN AND THE PULLING TO THE LEFT AND THE AUTOMATIC BREAKS WERE APPLIED. THE VEHICLE HAD TO BE TOWED TO THE DEALERSHIP WHERE IS STILL UNDER REPAIR. APPARENTLY THEY INDICATE THERE IS A TSB RELATED TO THIS MATTER. *AK

WHEN ATTEMPTING TO ACCELERATE AFTER BRAKING/SLOWING DOWN THERE IS A PERIOD OF SEVERAL SECONDS WITH NO RESPONSE FROM THE THROTTLE AND THEN SUDDENLY THE VEHICLE JERKS HARD AND ACCELERATES. WHEN MERGING INTO TRAFFIC THIS CAN POSE A SERIOUS SAFETY ISSUE. THE TOYOTA DEALER ADVISES THIS IS A NORMAL CONDITION AS THE VEHICLE "DRIVES BY WIRE" AND HAS NO MECHANICAL THROTTLE LINKAGE. THIS VEHICLE DIDN'T HAVE THIS ISSUE WHEN WE PURCHASED IT. THIS PROBLEM DEVELOPED AFTER WE HAD DRIVEN IT FOR A WHILE AND HAS PROGRESSIVLY GOTTEN WORSE. OTHER MANUFACTURERS ALSO USE THE DRIVE BY WIRE COMPONENTS AND DO NOT HAVE THIS PROBLEM I FIND IT HARD TO BELIEVE THAT TOYOTA CONSIDERS THIS A NORMAL CONDITION.*AK

THERE IS A DISTINCT DELAY IN THE ACCELERATION OF MY 2004 TOYOTA SIENNA VAN WHEN THE ACCELERATOR PEDAL IS DEPRESSED QUICKLY. THIS DELAY IS NOT NOTICEABLE UNLESS THE DRIVER IS ALREADY MOVING AND THE ACCELERATOR IS DEPRESSED IN SITUATIONS SUCH AS PASSING OR SOME OTHER ACTIVITY THAT REQUIRES QUICK ACCELERATION. I WAS TRYING TO SPEED UP WHILE DRIVING IN THE RIGHT HAND LANE OF A HIGHWAY BECAUSE THE LEFT LANE WAS ALREADY OCCUPIED AND A VEHICLE WAS ATTEMPTING TO MERGE ONTO THE ROADWAY. MY VAN DID NOT SPEED UP UNTIL IT WAS TOO LATE AND THE VEHICLE ATTEMPTING TO MERGE ONTO THE HIGHWAY DROVE OFF OF THE ROAD TO AVOID AN ACCIDENT. DURING ANOTHER OCCASION REQUIRING QUICK ACCELERATION A TRUCK LOCKED UP ITS' BRAKES TO AVOID HITTING ME FROM BEHIND WHEN I MERGED INTO HIS LANE AS I DEPRESSED THE ACCELERATOR ONLY TO HAVE THE VAN FAIL TO SPEED UP FOR TWO SECONDS. TOYOTA PERSONNEL FROM THE DEALERSHIP WHERE I PURCHASED THE VAN (WORLD TOYOTA OF CHAMBLEE, GA) INFORMED ME THAT THEY HAVE RECEIVED SIMILAR COMPLAINTS BUT THEY ARE UNABLE TO CORRECT THE PROBLEM BECAUSE IT IS THE RESULT OF A DESIGN FLAW IN THE VEHICLE IN THAT TOYOTA INSTALLED A LASER CONTROL ON THE ACCELERATOR IN LIEU OF AN ACCELERATOR CABLE THAT COULD BE ADJUSTED. *NM

2004 TOYOTA SIENNA EXHIBITS POOR LOW SPEED DRIVABILITY WHEN ACCELERATING FROM SLOW SPEED. THROTTLE DOES NOT RESPOND TO PEDAL ACTION WHICH RESULTS IN UNPREDICTABLE ACCELERATION TIME AND AMOUNT. POOR, OR NO, ENGINE RESPONSE IS FOLLOWED BY LURCH FORWARD AS THROTTLE (OVER) REACTS AND TRANSMISSION SEARCHES FOR THE PROPER GEAR. MANY 'NEAR MISSES' IN TRAFFIC MERGING SITUATIONS. THE PRIMARY DRIVER, MY WIFE, WILL NO LONGER USE THIS VEHICLE. SEVERAL DEALERS HAVE REVIEWED THIS ISSUE AND STATE THAT TOYOTA CLASSIFIES THIS PERFORMANCE AS A 'CHARACTERISTIC' OF THE 3.3L PLATFORM. THIS PERFORMANCE IS NOT ACCEPTABLE TO ME AND VEHICLE WILL BE REPLACED IF NOT REPAIRED SOON.*AK

ACCELERATOR FAILS TO RESPOND FOR 1-2 SECONDS IN AN EMERGENCY ACCELERATION SITUATION. WHEN ENTERING A ROAD FROM A STOP SIGN, I HESITATED THINKING THERE WAS NO ROOM. A VEHICLE LET ME IN. WHEN I HIT THE ACCELERATOR TO MAKE IT SAFELY, THE VEHICLE FAILED TO RESPOND FOR 1-2 SECONDS. THE CAR LETTING ME SLOWED DOWN TO LET ME IN, BUT NOT ENOUGH TO ALLOW FOR THIS DELAY AND HE NEARLY REAR-ENDED ME. IT WAS SCARY TO NOT HAVE THE CAR RESPOND. I HAVE SEEN MANY OTHER COMPLAINTS FILED ABOUT THIS AND THE DEALER RESPONSE ALWAYS SEEMS TO BE THAT THIS IS HOW THE ELECTRONIC THROTTLE CONTROL PERFORMS. I BELIEVE THIS NEEDS TO BE RECALLED SO THAT TOYOTA CAN MAKE THIS ELECTRONIC DEVICE RESPOND IMMEDIATELY AS OPPOSED TO TAKING 1-2 SECONDS.*AK

I NOTICED AN ARTICLE RECENTLY ABOUT A PROBE INTO TOYOTA'S (CAMRY AND LEXUS) THAT SURGE. MY 2004 TOYOTA SIENNA SURGES FORWARD WHEN BRAKING AND THOUGH IT DOES NOT DO THIS CONSISTENTLY, IT HAPPENS EVERY SO OFTEN AND COULD POTENTIALLY CAUSE AN ACCIDENT. I HAVE REPORTED THIS TO THE DEALER AND THEY HAVE EXAMINED THE VEHICLE AND SAID THAT THERE IS NOTHING WRONG. MY PERSONAL EXPERIENCE WITH THE ELECTRONIC THROTTLE CONTROL IS THAT NOT ONLY DOES IT SURGE WHEN BRAKING, THERE IS ALSO A DELAY IN THE SIGNAL WHEN ACCELERATING THAT EITHER CAUSES AN UNSAFE DELAY IN ENTERING INTO TRAFFIC AND CAN ALSO CAUSE THE VEHICLE TO "PEEL OUT" FROM A STOPPED POSITION. I BASICALLY FEEL UNSAFE IN THIS VEHICLE, YET MY CONCERNS VOICED TO THE DEALER HAVE BEEN DISMISSED. THIS DEFECT NEEDS TO BE SERIOUSLY MONITORED IN SIENNAS AS WELL AS OTHER TOYOTAS WITH THE ELECTRONIC THROTTLE CONTROL.*AK

ENGINE IDLES VERY FAST IN COLD WEATHER FIRST FEW MINUTES. WHILE DRIVING A BLOCK TO THE FIRST STOP SIGN HAS TO APPLY THE BRAKES VERY FORCEFULLY TO GET THE CAR TO STOP. THIS CAUSES SOME LOSS OF CONTROL , ESPECIALLY ON A SLIGHT DOWN HILL SLOPE DURING SNOWY/ICY WEATHER. APPEARS TO BE COMBINATION IDLE, AND THE AUTOMATIC TRANSMISSION.*AK

VEHICLE HESITATES/FAILS TO MOVE FORWARD IN THE FOLLOWING MODE: AFTER BRAKING, WHEN THE VEHICLE IS STILL MOVING BETWEEN 5 TO 15 MPH, THE VAN DOES NOT RESPOND TO ACCELERATOR PEDAL INPUT; VEHICLE HESITATES WITH NO MOVEMENT FORWARD, THEN SHIFTS HARD INTO FIRST GEAR AND LURCHES FORWARD. WE HAVE HAD 2 CLOSE CALLS, WAITING FOR THE VEHICLE TO RESPOND TO ACCELERATOR PEDAL INPUT. ALSO, ACCELERATOR PEDAL HAS A DEAD SPOT. THE FIRST HALF INCH OF PEDAL CAUSES NO RESPONSE FROM VEHICLE). THIS "DEAD SPOT" ALONG WITH THE HESITATION NOTED ABOVE CAN RESULT IN A 2 SECOND RESPONSE FAILURE FROM THE VEHICLE. THIS SITUATION HAS PUT MY FAMILY IN HARMS WAY ON NUMEROUS OCCASIONS.*AK

I RAN INTO A BIG PROBLEM WITH MY 4 MONTH OLD 2004 TOYOTA SIENNA XLE. I WAS TURNING ONTO A HILL AND WANTED TO SEE HOW IT WOULD ACCELERATE UP THE HILL SO I FLOORED IT. THE CAR ACCELERATED WELL AND I TOOK MY FOOT OFF THE GAS PEDAL AT ABOUT 35 MPH. THE PROBLEM WAS THAT THE CAR KEPT GOING AT FULL ACCELERATION. THERE WAS NO ONE IN FRONT OF ME SO I STARTED TRYING TO FIGURE OUT HOW TO STOP IT INSTEAD OF JUST TURNING OFF THE CAR (I NEEDED TO GET TO THE TOP OF THE HILL AND I COULD COAST TO WHERE I WAS GOING). I PUT IT INTO NEUTRAL BUT ALL IT DID WAS REV TO 6000 RPM, I CHECKED TO MAKE SURE I SOMEHOW HADN'T GOTTEN THE CRUISE CONTROL ON AND I HADN'T, I DOWNSHIFTED INTO 3RD AND KEPT PRESSING ON AND LETTING OFF THE BRAKE PEDAL SINCE I DIDN'T WANT RUIN MY BREAKS (I WAS ABLE TO KEEP THE SPEED BETWEEN 40 AND 50). AS I NEARED THE TOP OF THE HILL (IT IS ABOUT 1/3 OF A MILE LONG) I FIGURED I WOULD TURN THE CAR OFF AT THE TOP. JUST AS I WAS ABOUT TO CREST THE HILL, THE VAN STOPPED ACCELERATING AS THE CAR LEVELED OUT AND THEN RAN NORMAL. THERE IS AN INITIAL LEVEL PORTION GOING TO THE TOP OF THE HILL AND THE VAN DID NOT STOP ACCELERATING AT THE LEVEL SPOT. IT WASN'T UNTIL THE SECOND LEVEL SPOT THAT IT STOPPED ACCELERATING.. *AK
