Shifter not shifting into park even when in park causing it to roll even when you think it’s in park
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
The Traction Control System commonly malfunctions while making turns on curving road sections. I will lose power through turns as the TCS light blinks on my dashboard and makes a beeping sound. On some occasions the brakes will automatically engage in the tire that the car perceives as experiencing slippage. This problem is continuously worsening and commonly endangers me and my passengers, as the car engages brakes or cuts power to the engine at unexpected and in opportune times.
While driving typically around 35 mph and either left or right turn the vehicle traction control engages and the van brakes and steering is affected. The roads have always been dry and in each instance the speed of the van was at or below the speed limit - traction was never lost and yet the traction control engaged as if we were in a skid. This occurred at least 12 times while driving to and from a day trip in the mountains (windy road). It has also happened multiple times at around 50 mph while turning left on a nearby flat freeway. An independent service shop has not been able to replicate the problem. The safety of the driver and passengers were at risk when it occurred on the freeway as a driver behind us got close to rear ending the van while it was in its brake mode.
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.
When opening the rear hatch, it will not stay open and slams down if you let it go. Incredibly dangerous. I turned of the power doors and it still happens. I'm planning to take it to the dealership tomorrow.
Driving on dry roads at speed not exceeding 35 mph, the traction control system activates. It has happened on slight curves to the right. The traction control symbol lights up, a beeping sound occurs and it feels like the vehicle is braking. It has happened now on several occasions.
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 slip indicator light and alarm comes on sporadically, engaging the ABS suddenly and unexpectedly, when we are on completely dry roads. Happens while driving 40-80 mph. And doesn’t matter if I’m going straight or turning.
The trac control is activated while the car is driving variable speed and brake the car and and the driver loose control of acceleration.
The contact owns a 2004 Toyota Sienna. The contact stated while the vehicle was parked, the tailgate inadvertently opened, then closed independently. There was no warning light illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed that the tailgate hydraulic struts needed to be replaced. The vehicle was repaired; however, the failure recurred. The contact stated that she noticed that the failure had reoccurred in 30-degree temperatures on two occasions. The dealer and the manufacturer were not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 140,000.
- 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.
The 2004 Toyota Sienna van VSC Trac warning light and alarm come on when making turns on highway ramp under normal speed at around 35 mph.
The failing component is the VSC/ABS system. It puts the occupants of the van and other motorists at risk of either causing a collision or causing the driver of vehicle in question to be unable to control the vehicle . The failure appears when going in a curve in the road at low speed causing the abs to engage lock the brakes and steering wheel rapidly decelerating the car and causing the car to jerk to one side or the other and go into a skid where the driver is unable to control the wheel due to steering wheel locking up when it happens the VSC and TRAC lights come on and there is a loud and rapid beeping that can be heard inside the vehicle. The issue usually appear when going between 25-40mph in banking curves
Passenger right slider Will not open! Only opens About 8 inches. This is a safety hazzard for a passenger back seat r/h! This is well known condition! Could be deadly, in the right Surcomstance
Toyota VSC and ABS engaging and activating for no reason on dry pavement causing loss of proper control of the vehicle. The have been multiple occurrences on dry pavement between 30 and 65 mikes per hour. The car pulls to one side as the computer takes control of the car end engages the brakes suddenly for no reason. VSC Skid light goes on on the dash and there is a beeping sound while this happens. Very dangerous. Toyota USA notified and assigned case number 220201001364. They refuse to take any responsibility for this dangerous failure.
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
While driving on dry freeway or other stable road conditions, the Electronic Stability Control kicks in, braked hard, causing the van to swerve, and the lights on the dash started flashing, accompanied by a loud beeping. This has happened multiple times now. There is no reason for this to be occurring. It is involuntary, sudden, and random. If someone were close behind me, they could rear-end the vehicle. It also sometimes pulls the steering so hard that it swerves into the other lane. This is a serious safety issue that Toyota needs to deal with.
While driving at approximately 30 to 50 MPH, on dry and smooth pavement, usually going on or off ramp to the left, the skid control engaged and warning sound came on, automatic brake takes over and start braking the van uncontrollably, pulling the vehicle to the right and nearly causing accidents.
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
Manual sliding driver side door has stopped latching in the fully open position.

Drivers side seat belt broke and was replaced. Fuel sensor not replaced causes vehicle to hesitate at times at freeway speed
Numerous times (too many to say), the traction control indicator sensor comes on & I am unable to control the car. Typically it lasts for 2-3 minutes and turns off. It does not depend on road conditions, weather, and or speed. I have taken the car to the repair shop and they have not been able to capture anything on the engine diagnostic system. No codes were found for them to troubleshoot this issue. I've seen this problem being reported on several posts. Yet the NHSTA has done NOTHING!! TOYOTA NEEDS TO BE HELD LIABLE FOR THIS ISSUE. WAKE UP NHSTA. MAKE OUR TAX DOLLARS WORK!!! This poses a huge risk to my family and other drivers, not to mention impact on budget.
Issue with traction (maybe called a VSC system-stability), when going up and down hills with slight curves, the wheels lock up and the vehicle slows down. Even when exiting a freeway ramp that is at a slight decline and curve. This started happening about 3 1/2 years ago, just once in a great blue moon. It started happening more frequently in the past year. Neither Carson or South Bay Toyota dealership could tell us why and could not find anything wrong after they inspected it. We took it to an independent service location and they could not find out why either. We looked it up online and apparently many Toyota Sienna owners are happing the same issue and no resolution. The VSC Trac light comes on when it happens and they goes away. It does not happen all the time. Safety issue for us, we can not really control the van when the wheels lock up and safety issues for all (us and others around us) is the fact that the van slows down and wheels lock up, which could cause someone to hit us.
FROM THE TIME I PURCHASED MY 2004 TOYOTA SIENNA, THE DRIVER-SIDE SEAT BELT HAS NEVER WORKED PROPERLY. MOST OF THE TIME IT WOULD NOT RETRACT, BUT WAS SOMETIMES FIXABLE BY MOVING THE HEIGHT ADJUSTER UP AND DOWN. SOMETIMES IT WOULD BE OVER-EXTENDED FOR DAYS, THEN RETRACT ON ITS OWN. IT IS NOW FULLY EXTENDED AND UNABLE TO RETRACT. I MADE AN APPOINTMENT TWO WEEKS IN ADVANCE WITH A TOYOTA DEALERSHIP (80 MILES AWAY) TO FIX IT BUT, BECAUSE OF A MISCOMMUNICATION, THEY WERE PREOCCUPIED WITH REPAIRING FOUR RECALL ISSUES AND NEGLECTED TO ADDRESS THE SEAT BELT PROBLEM. INSTEAD, THEY GAVE ME AN ESTIMATE OF $335 TO REPLACE IT. THE FOLLOWING STATEMENT, DATED JAN 7, 2016, WAS SENT TO OWNERS OF 2004-2006 TOYOTA SIENNAS. APPARENTLY THE FORMER VEHICLE OWNER DID NOT FOLLOW THROUGH. I PURCHASED THE VEHICLE FROM A MAUI DEALERSHIP IN OCTOBER OF 2018. "WARRANTY ENHANCEMENT PROGRAM ' ZF2 2004 ' 2006 MODEL YEAR SIENNA VEHICLES EXTENSION OF WARRANTY COVERAGE FOR FRONT SEATBELT ASSEMBLIES TOYOTA HAS RECEIVED A NUMBER OF REPORTS REGARDING FRONT SEATBELTS IN CERTAIN 2004 ' 2006 MODEL YEAR SIENNA VEHICLES. IN THESE REPORTS, CUSTOMERS HAVE INDICATED THAT THE FRONT SEATBELTS (RIGHT AND/OR LEFT) MAY SLOWLY OR NON-SMOOTHLY RETRACT. ALTHOUGH THE FRONT SEATBELT ASSEMBLY IS COVERED BY TOYOTA'S NEW VEHICLE LIMITED WARRANTY FOR 5 YEARS OR 60,000 MILES (WHICHEVER COMES FIRST), WE AT TOYOTA CARE ABOUT THE CUSTOMERS' OWNERSHIP EXPERIENCE. TOYOTA IS NOW EXTENDING THE WARRANTY COVERAGE FOR REPAIRS RELATED TO SLOW OR NON-SMOOTH RETRACTION OF FRONT SEATBELTS." SINCE THIS IS OBVIOUSLY A COMMON AND HAZARDOUS PROBLEM WITH 2004-2006 SIENNAS, IT SEEMS LIKE IT SHOULD BE WARRANTIED UNDER A RECALL PROGRAM.
ONE OF THE TWO SUPPORT CYLINDERS FOR THE REAR HATCH ON OUR 2004 TOYOTA SIENNA FAILED IN FALL 2019, SO THE REAR HATCH WOULD NOT STAY UP. THE LIFTGATE SUPPORT CYLINDERS HAD PREVIOUSLY BEEN REPLACED BY TOYOTA UNDER RECALL. WE PURCHASED TWO NEW SUPPORT CYLINDERS, TOYOTA PART #68905-AE022'SUPPORT CYLINDER' FROM CAMELBACK TOYOTA IN PHOENIX, AZ, D/B/A TOYOTA PARTS FACTORY, BY MAIL, SHIPPED 11/19/19. I INSTALLED BOTH OF THE NEW SUPPORT CYLINDERS WITHIN A COUPLE OF WEEKS. NOTE THAT BOTH OF THE OLD SUPPORT CYLINDERS WERE REPLACED WITH NEW TOYOTA PARTS, NOT JUST THE ONE WHICH HAD FAILED. HOWEVER, WITH THE NEW SUPPORT CYLINDERS, WHEN THE WEATHER GETS COOL (BELOW 50 F) AND THE LIFTGATE IS OPENED USING THE ELECTRIC OPENER, THE LIFTGATE GETS PART WAY UP AND REVERSES, COMING DOWN UNEXPECTEDLY. THIS REPRESENTS A SAFETY HAZARD, AS THE DOOR CAN HIT SOMEONE STANDING BELOW IT. THIS IS EXACTLY THE BEHAVIOR FOR WHICH TOYOTA ISSUED THE RECALL ON THE SUPPORT CYLINDERS. THE UNEXPECTED REVERSING HAPPENS ON LEVEL GROUND WITH NORMAL USE OF THE LIFTGATE. IT STARTED HAPPENING SHORTLY AFTER THE NEW SUPPORT CYLINDERS WERE INSTALLED. TOYOTA CUSTOMER SERVICE TODAY TOLD ME THAT THEY WOULD NOT WARRANTY THE SUPPORT CYLINDERS, EVEN THOUGH THIS IS A SAFETY ISSUE. AS THE PROBLEM STARTED OCCURRING WHEN THE 2019 SUPPORT CYLINDERS WERE ESSENTIALLY NEW, THERE IS NO ASSURANCE THAT REPLACING THEM AGAIN WOULD SOLVE THE PROBLEM. IT APPEARS THAT TOYOTA IS SELLING REPLACEMENT SUPPORT CYLINDERS WHICH DO NOT MEET THE LIFTGATE'S SUPPORT REQUIREMENTS.
PART # 69300-08011 REAR LEFT DOOR LATCH WITH POWER SLIDING DOOR MALFUNCTION CAUSING A SAFETY PROBLEM DOOR REMAINED OPENING AND CLOSING COULD CAUSE PASSENGER OR ITEMS TRANSPORTING TO FALL OUT OF VEHICLE .IT ALSO CAUSED BATTERY TO DRAIN VEHICLE WOULDN'T START WITHOUT BEING JUMPED EVEN REPLACED BATTERY WITH A NEW BATTERY SAME THING HAPPENED . THIS PART HAS BECOME A PROBLEM IN MANY OF THESE 2004 TOYOTA SIENNA MINI VANS . A SAFETY RECALL NEED TO BE CONCIDERED .
ABS SOME TIMES ACTIVATES WHEN DRIVING A LIGHT CURVE ROAD AT SPEED AROUND 30-40 MPH. USUALLY A STEERING WHEEL IS ABOUT 2 OR 10 O'CLOCK POSITIONS. AT THE TIME VSC INDICATOR FLASHES AND WARNING ALARM GOES OFF. THIS CAUSES A SUDDEN BREAKING AND IT BECOMES VERY DIFFICULT TO CONTROL THE CAR.
THE VSC SYSTEM IS ENABLING WHILE DRIVING AND MAKING A TURN ON AN OTHERWISE NORMAL ROAD. WHEN IT ENABLES, IT APPLIES THE BRAKE AND SOUNDS A REPEATING ALARM. THE SYSTEM APPLIES THE BRAKE WHILE I AM ATTEMPTING TO MAKE A TURN, AND THIS MAKES ME FEEL UNSAFE, AS IF I HAVE TEMPORARILY LOST CONTROL OF THE VEHICLE WHILE MAKING AN OTHERWISE BENIGN MANEUVER. THE REPEATING ALARM DOES NOT TURN OFF UNTIL I HAVE TURNED THE WHEEL TO THE OPPOSITE DIRECTION FROM THE INITIAL TURN ANGLE. THIS MEANS IF THE TURN IS SLOW, THE ALARM WILL SOUND FOR THE ENTIRE DISTANCE OF THE TURN.
IN MOTION, ON DRY, OFF-CAMBER HIGHWAY CURVES, WITH SLIGHT ACCELERATION, THE ABS/VSC /TRAK ENGAGES, BRIEFLY JERKING THE STEERING TO ONE SIDE. DASH WARNINGS: "VSC" "TRAK OFF" + "CHECK ENGINE". REDUCING MECHANICAL "SLOP" (WHEEL BEARINGS, STEERING RACK & PINION, ETC.) TENDS TO REDUCE FREQUENCY OF OCCURRENCE. TOYOTA DEALER DIAGNOSIS: "STEERING CONTROL SYSTEM FAULT". >"TOYOTA KNOWS ABOUT -- BUT, DOES NOT KNOW HOW TO FIX THIS PROBLEM."< DEALER-SUGGESTED WORKAROUND: "PULL FUZES TO DISABLE VSC AND ABS SYSTEMS..." DEALER REPAIR DOCUMENTS ARE WITH PREVIOUS OWNER...
I ARRIVED AT MY DESTINATION AND WENT TO PUT IT IN PARK AND IT WOULDN'T GO. IT WOULDN'T REVERSE EITHER. MY HUSBAND CHECKED IT OUT AND SAW THE TRANSMISSION SHIFT CABLE BUSHING WAS HANGING. WE LOOKED IT UP AND THERE WAS A RECALL FOR THE 2006 SIENNA.
WE BOUGHT THIS CAR ABOUT 1 1/2 YEARS AGO. AFTER HAVING IT FOR A BIT WE LEARNED OF THE PROBLEM. YOU WILL BE DRIVING DOWN THE ROAD (DRY, SUNNY DAY) AND ALL OF A SUDDEN THE CAR WILL START BEEPING, THE TRACTION CONTROL WILL KICK IN AND START PRESSURE BRAKING THE CAR. THE CAR THINKS IT PULLING YOU OUT OF A SKID, SO YOU HAVE TO STRONGLY HOLD THE STEERING WHEEL. IT'S TERRIFYING! I FEEL LIKE THE CAR IS GOING TO PULL ME OFF THE ROAD. I WON'T DRIVE THE CAR IN RAIN BECAUSE OF THIS AND HONESTLY DON'T FEEL COMFORTABLE EVEN DRIVING IT MOST THE TIME. YOU NEVER KNOW WHEN IT IS GOING TO HAPPEN AND IT TYPICALLY HAPPENS WHILE YOU ARE DRIVING HIGH SPEEDS ON THE HIGHWAY. THIS IS A KNOWN PROBLEM WITH TOYOTA - THEY HAVE A TECHNICAL SERVICE BULLETIN BR008-04 (ABS& TRACTION CONTROL INTERMEDIATE VSC SYSTEM), WHICH SHOWS THEY HAVE REPLACED THE DEFECTIVE PART. HOWEVER SINCE THE CAR IS OLD, THEY WON'T REPLACE IT ANYMORE. IT IS THE COMPANIES DEFECT PART! HOW MANY PEOPLE HAVE GOTTEN INTO ACCIDENTS AND/ OR DIED FROM THIS? AND JUST TO SAY IT - THE 2004 VERSION DOESN'T HAVE A WAY TO MANUALLY JUST TURN OFF THE TRACTION CONTROL. WE HAVE TRIED EVERYTHING! I TOOK IT TO A TOYOTA DEALERSHIP AND THEY AGREED THIS IS WHAT IS WRONG WITH THE CAR, BUT SAID THEY WON'T FIX IT FOR FREE - THEY WANTED $800. I CONTACTED TOYOTA CUSTOMER AND THEY BASICALLY TOLD ME THEY DON'T CARE IF PEOPLE DIE FROM THIS, BECAUSE THE CAR IS OLD AND THEY DON'T HAVE ANY RESPONSIBILITY AFTER A CERTAIN AGE OF THE CAR. WE HAVE 3 KIDS AND THIS IS NOT AN ACCEPTABLE ANSWER! MY WHOLE FAMILY HAS TOYOTA VEHICLES AND IF THEY DON'T MAKE THINGS LIKE THIS RIGHT, WE WILL NOT BE ANYMORE! THE CAR IS NEW TO US AND IS FRANKLY UNSAFE. THIS IS TOYOTA'S FAULTY PART. I HAVE SEEN SEVERAL MESSAGE BOARDS WITH THE SAME ISSUE. HOW CAN A DEADLY ISSUE EXPIRE?
THIS VEHICLE HAS A TRACTION CONTROL FEATURE WHICH HELPS KEEP IT FROM SKIDDING OUT OF CONTROL IN ICY, WET, OR OTHERWISE UNSTABLE CONDITIONS. IT CAN HELP AN OUT OF CONTROL VEHICLE GET BACK INTO CONTROL BY DOING A VARIETY OF THINGS, INCLUDING BRAKING. PREVIOUSLY THIS FEATURE HAD ONLY KICKED ON WHEN I WOULD SLIDE ON THE SNOW DURING A LOW SPEED TURN AND WOULD SLIDE IN THE SNOW (WHICH WAS GOOD). BUT OVER THE PAST FEW MONTHS, THERE HAVE BEEN TWO TIMES THAT THIS FEATURE HAS KICKED ON AT HIGH SPEEDS (ONCE AT 40MPH AND ONCE AT 65MPH) ON DRY ROADS, BOTH WHILE TURNING AROUND A CURVE. SUDDENLY THE BRAKING SYSTEM IS APPLIED WITHOUT ANY WARNING AND THE VEHICLE SWERVES SLIGHTLY AND DOES WHAT IT WANTS FOR A FEW SECONDS. THEN IT STOPS. IF THIS WERE TO HAPPEN ON AN ICY ROAD AT THOSE SPEEDS, THE VEHICLE COULD CERTAINLY SPIN OUT OF CONTROL. THE VEHICLE COULD ALSO SWERVE INTO AN ONCOMING LANE OF TRAFFIC. I HAVE SEEN MANY FORUMS ONLINE WHERE OTHER SIENNA OWNERS ARE HAVING THE SAME ISSUE AND TOYOTA DEALERS SAY THEY CAN'T REPLICATE OR FIX THE ISSUE. THIS IS CERTAINLY A SAFETY ISSUE THAT NEEDS TO BE LOOKED INTO BY TOYOTA TO SEE WHAT IS CAUSING THIS ISSUE. THANK YOU! *TR
IN SEPT-OCT OF 2019 TOOK VAN INTO [XXX] AND TOLD THEM ABOUT A LEAK THAT WOULD PUDDLE IN PASSENGER RIGHT FRONT SEAT. [XXX] SAID ITS AFTERMARKET NOTHING WE CAN DO.

DRIVING AT 50 MPH ON A TWO LANE HIGHWAY THE CAR SUDDENLY VEERED TO THE RIGHT AND DECELERATED/BRAKED HARD, UNDER IT'S OWN CONTROL, NOT MINE.
SLIDING DOORS DON'T PROPERLY LATCHED LIKE THEY ARE SUPPOSE TO WHEN ATTEMPTING TO CLOSE DOOR CAUSING A SAFETY ISSUE FOR PASSENGERS . IT HAPPENS WHEN VEHICLE IS PARKED OR MOTION ON ROAD WAY OR IN PARKING SPACE .
Driver's side seat belt buckle stopped locking in seat belt. Buckle unit then came apart. I called toyota; was informed that there was a recall on this matter. I was told that I was 2 years past the scope of the recall. I informed them I never received a notice of recall so how would I be aware of problem until it occurred. Spoke to supervisor was told I was no longer covered under recall. Went to 2 mechanics and was unable to obtain needed part. I feel that for this safety item there should be no time limit on a recall and I felt Toyotas help in remeding the situation was poor especially as they tout their vehicles safety.
WHILE DRIVING AT OR BELOW THE SPEED LIMIT, UNDER DRY CONDITIONS, ON CURVY ROADS, THE VSC DASH LIGHT COMES ON AND ENGAGES WITH BEEPING AND AUTOMATIC BRAKING. THE RAPID DECELERATION AND SKIDDING, AS THE TIRES LOCK-UP, MAKES CONTROL OF THE VEHICLE DIFFICULT AND CARS FOLLOWING MUST PANIC BRAKE TO AVOID REAR-ENDING MY VEHICLE. INCREASING OCCURRENCES OVER THE PAST YEAR.
BOTH POWER SLIDING DOORS FREEZE SHUT ANY TIME THERE ARE FREEZING TEMPERATURES AND ANY MOISTURE, AND CANNOT BE OPENED EITHER WITH POWER OR MANUALLY. ATTEMPTING TO OPEN A DOOR WILL ONLY OPEN IT 1/4", SUFFICIENT TO ACTIVATE THE DOME LAMPS, BUT THEN WILL NOT CLOSE. AFTER DRIVING AND WARMING UP, THE DOOR MAY RANDOMLY OPEN AT ANY TIME, PRESENTING A SAFETY HAZARD.
UNINTENDED ACCELERATION PROBLEM. TWO EPISODES, MONTHS APART, BOTH AT VERY LOW SPEED. WAS STOPPED BEHIND TWO CARS. TWO CARS IN FRONT STARTED UP TO GO THROUGH INTERSECTION. I TOOK MY FOOT OFF THE BRAKE AND MOVED IT TO THE GAS PEDAL. CAR STARTED UP NORMALLY. THEN A CHILD PUSHED TO CROSSWALK SIGNAL WHICH STARTED TO FLASH. I MOVED MY FOOT TO THE BRAKE PEDAL, AND THE CAR STARTED SLOWING DOWN NORMALLY, BUT THEN THE CAR SUDDENLY LURCHED FORWARD. BOTH I AND THE PASSENGER THOUGHT WE HAD BEEN REAR-ENDED (BUT THERE WAS NO CAR BEHIND). IT WAS A SIMILAR FEELING TO WHEN THE CRUISE CONTROL KICKS IN TO ACCELERATE, BUT NO CRUISE CONTROL HAD BEEN ACTIVATED. I TOOK MY FOOT OFF THE BRAKE AND SLAMMED IT BACK ON THE BRAKE, AND THE CAR STOPPED. THE PREVIOUS EPISODE HAD A SIMILAR SERIES OF EVENTS.
1) SEATBELT TWISTS AND GETS JAMMED IN THE GUIDE NEAR THE RETRACTOR. SEAT BELT PULLS OUT, BUT THEN WILL NOT RETRACT AS IT IS WEDGED IN THE GUIDE.THIS HAS HAPPENED NUMEROUS TIMES, BUT NOW IT IS QUITE WEDGED. AND UNUSABLE AT THE MOMENT. 2) CABLE THAT PULLS THE SIDE DOOR OPEN AND CLOSED HAS RUSTED AND BROKEN. THIS WAS SUBJECT TO A TOYOTA VOLUNTARY SERVICE CAMPAIGN, BUT MY PROBLEM STARTED AFTER THE EXPIRATION OF THE SERVICE CAMPAIGN.
TOYOTA ISSUED A NATION-WIDE EXTENDED WARRANTY COVERAGE IN 2015 FOR ITS MELTING DASHBOARDS CAUSED BY MANUFACTURING DEFECT, 2004-2010 SIENNA, 2007-2011 CAMRY, 2004-2008 SOLARA, 2005-2010 AVALON, 2003-2005 4RUNNER, TOTAL OF 3.42 MILLION VEHICLES AFFECTED. THE EXTENDED WARRANTY LASTED FOR TWO YEARS UNTIL 2017 AND SOME CARS HAVE DEVELOPED THE SYMPTOMS SLOWER THAN OTHERS PARTICULARLY FOR THOSE WITH LESS MILEAGE AND/OR LESS EXPOSURE TO SUN. NOW THE MELTING DASHBOARDS ARE CREATING SERIOUS DRIVING HAZARD WHEN DRIVING INTO SUN BECAUSE THE REFLECTION IS BLOCKING THE DRIVER'S VIEW. THEREFORE, IT CALLS FOR A RECALL SINCE DRIVING HAZARDS DO NOT HAVE EXPIRATION DATES.
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.
TRANSMISSION MADE A NOISE WHEN I WAS SLOWING DOWN OFF THE HIGHWAY. NOW I LOST REVERSE IN TRANSMISSION
WHEN DRIVING IN DRY CONDITIONS AT VARIOUS SPEEDS OVER 25 MPH, THE VSC WARNING LIGHT COMES ON, AN ALARM SOUNDS AND THE ANTILOCK BRAKES ENGAGE FOR NO REASON. THIS IS A TERRIFYING AND EXTREMELY DANGEROUS ISSUE THAT IS WELL DOCUMENTED BY SO MANY TOYOTA SIENNA OWNERS BUT TO DATE HAS NOT BEEN ADDRESSED OR ACKNOWLEDGED BY TOYOTA. WHEN TAKEN TO A DEALERSHIP, THEY CLAIM (AS OTHER OWNERS HAVE ALSO STATED) THAT THEY CANNOT REPLICATE THE PROBLEM AND IT DOES NOT REGISTER THROUGH THE OBD2 SENSOR SO THERE IS NO RECORD OF IT HAPPENING. WITH AS MANY PEOPLE AS THIS IS HAPPENING WITH, IT IS NOT A QUESTION OF WHETHER THERE WILL BE ACCIDENTS, INJURIES AND ULTIMATELY DEATHS CAUSED BY THIS ISSUE. THE ONLY QUESTION IS WHEN AND HOW MANY HAVE TO OCCUR BEFORE TOYOTA ACKNOWLEDGES THIS IS A PROBLEM. DRIVING DOWN THE ROAD, IN TRAFFIC AT 65 MILES AN HOUR WHEN FOR NO REASON, THE CAR SLAMS ON THE BRAKES WITHOUT WARNING. IT IS HAPPENING ALL THE TIME AT THIS POINT MAKING THE CAR COMPLETELY UNSAFE TO DRIVE FOR THE OWNER, THE VEHICLE'S OCCUPANTS AND ANY UNSUSPECTING VEHICLE IN THE VICINITY. I AM BEGGING YOU. PLEASE GET TOYOTA TO ISSUE A RECALL BEFORE TRAGEDY STRIKES. THANK YOU FOR YOUR PROMPT ATTENTION TO THIS MATTER. I AM SUBMITTING THE DATE BELOW AS TODAY'S DATE AS THE CAR IS NOW SITTING IN MY DRIVEWAY UNTIL I CAN FIGURE OUT WHAT NEEDS TO BE DONE. IT HAS HAPPENED OVER THE PAST 6 MONTHS EVERY TIME I DRIVE IT AND THE $750 STEERING POSITION SENSOR THAT TOYOTA REPLACED DID NOTHING TO ADDRESS THE PROBLEM.
WHILE MY VEHICLE IS IN MOTION ON CITY STREETS AND HIGHWAYS AT SPEEDS BETWEEN 35 AND 55 MPH, ON A STRAIGHTAWAY AND CURVE, THE STABILITY CONTROL LIGHT/AND ALARM COMES ON RANDOMLY. SOMETIMES IT'S JUST THE ALARM THAT SOUNDS, AND SOMETIMES THE ALARM SOUNDS AND THE BRAKES ACTIVATE AND THE MINIVAN SWERVES. WAS THE MOST FRIGHTENING AND DANGEROUS EXPERIENCE EVER WITH MY YOUNG GRANDCHILDREN RIDING WITH ME. I ACTUALLY HAD TO PULL OVER TO THE SIDE OF THE ROAD TO CALM MYSELF. THIS HAS NOW HAPPENED ON SEVERAL OCCASIONS WITH TODAY (7-24-19) BEING THE LATEST EXPERIENCE.
STARTED HAVING PROBLEM WITH THE DOORS ON THE VAN THE FRONT DOOR WAS THE FIRST PROBLEM WITH A FAILED DOOR CHEEK CAUSING THE DOOR NOT TO BE ABLE TO BE OPENED HAD TO FORCE IT OPEN AND REMOVE THE DOOR CHEEK DUE TO A WELD THAT HAD BROKEN AWAY FROM THE DOOR IS WHY IT FAILED AND THE SECOND WAS THE POWER SLIDING DOOR ON THE PASSENGER SIDE THE DOOR QUITE WORKING AND THEN WHEN SWITCHED INTO THE MANUAL MODE I WAS UNABLE TO GET THE DOOR TO CLOSE OR IT WOULD CLOSE THEM COME BACK OPEN IT TOOK ALMOST A HOUR TO GET IT TO CLOSE AND STAY CLOSED. THIS BEING THE CAR I TRANSPORT MY KIDS IN THAT'S A BIG SAFETY ISSUE TO ME KNOWING THE DOOR MAY NOT WORK OR MAY NOT SAY CLOSED WHILE DRIVING PLEASE HELP.
