Recently reported VEHICLE SPEED CONTROL problems on 2004 Toyota Sienna

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.

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

Tl*the contact owns a 2004 toyota sienna. the contact stated that after shifting into reverse, the vehicle accelerated independently. the contact stated that the brakes were depressed, but failed to stop the vehicle. the vehicle went over the curb, and was stopped by a pile of snow. the vehicle was not diagnosed or repaired. the manufacturer was not notified of the failure. the approximate failure mileage was 150,000.

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

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

while driving the vsc activates, the brakes engages, the cars slows down and it make it difficult to control. it has happened to me more than 10 times. mind you its on a dry surface and no curves. very scary i drive it with nobody inside just in case... thanks *tr

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.

Tl* the contact owns a 2004 toyota sienna. the contact stated that while driving at approximately 45 mph, the traction warning light illuminated. in addition, the contact stated that the vehicle accelerated independently. the failure occurred on several occasions. the vehicle was taken to the dealer where the failure was unable to be determined. the vehicle was not repaired. the manufacturer was notified of the failure. the approximate failure mileage was 130,000. ..updated 12/02/14 *bf the dealer attempted to fix the vehicle three times. updated 01/13/15

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

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.

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

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

2004 toyota sienna. consumer writes in regards to vehicle accident and shift lock solenoid recall notice, received after accident. *smd the consumer and her husband were involved in an accident, when the vehicle suddenly surge forward, after turning into a parking spot. the vehicle violently crashed into the concrete storefront wall. also, the air bags did not deploy. the vehicle was totaled. *jb updated 08/07/14

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

Driver had foot on brake to complete parking in driveway when car had sudden surge of acceleration and 'jumped' into a wheelbarrow and a pile of dirt beyond and the vehicle came to a stop. dealer checked car and said there was nothing wrong with it. *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

Complete loss of power while in motion entering freeway. previously had noticed steering difficulty at times and engine light going on, but had always stopped after a short while. after the failure it was diagnosed as failure of crank shaft pulley. we found that toyota had done a recall for this issue, but had not included our vehicle in the recall or notified us. toyota denied coverage of the required repair. driver and two small children in care at time of failure, just about to enter freeway. over $800 in repairs. *tr

We will be going anywhere from 35 to 55 miles and our vsc light comes on and the van slows, other times the speed will slow it self and than will speed up on it's own. when that (vsc) light and sound comes on the van will also skid. there must be something wrong with vsc system. this van is still in very good condition, we sure swish someone could tell us what the problem is this seems to be a very serious matter. reading all the other complaints this is not random and toyota should give this matter serious consideration. *tr

Tl* the contact owns a 2004 toyota sienna. the contact stated that while at a complete stop the vehicle suddenly accelerated. the vehicle accelerated through a parking lot and crashed into two vehicles. the failure was the third occurrence since of unintended acceleration in the vehicle. the vehicle was taken by the united states automobile association and was being held in storage. the vehicle was not inspected for the cause of the failure. the failure and the current mileages were 97,000. updated 12/13/12 *cn the consumer the first occurence, on january 11/2012, the vehicle was being backed out of a parking space, then the vehicle acclerated. a light fixture was damaged on a side walk. the next occurence, on january 26, 2012, the vehicle was being pulled into a parking space, the vehicle ran over the curb and damaged a disability sign. updated 1/2/2013 *js

Vsc (vehicle stability control) is activated in curves at speeds between 25 mph and 60 mph. surface is dry and curves are gradual with appropriate and safe driving speeds. the vsc light goes on and warning buzzer goes off. the brakes shudder and the vehicle is de-throttled. vehicle control is reduced for 3 to 5 seconds and then the vsc deactivates. concerned that this will be a problem when the road surface is slick. dealer could not find malfunction codes and could not duplicate problem so no fix. this situation occurs almost every day at least once. keeping incident log. web sites indicate this could be steering sensor calibration. dealer cleaned sensor parts and this did not resolve problem. contacted toyota and they said to continue working with the dealer. tsb is out for yaw sensor failure and steering calibration. *tr

Tl* the contact owns a 2004 toyota sienna. while stopped in parking space with the gear in reverse, the vehicle accelerated independently and crashed into a lamp post. the failure occurred a second time while stopped on an incline with the brake pedal depressed. the contact then crashed into two other vehicles. the police reported to the scene and a report was filed. the vehicle was towed to an auto shop where it was inspected by the insurance company. the vehicle was deemed as destroyed. the cause of the failure was not determined. the vin was not available. the approximate failure mileage was 87,000.

Tl* the contact owns a 2004 toyota sienna. the contact stated that while driving approximately 30 mph, the vehicle speed control warning light illuminated and the front driver side wheel hesitated. in addition, the contact stated that the vehicle lost power abnormally. the failure was experienced numerous times. the vehicle was not taken to the dealer to have a diagnostic performed. the vehicle was not repaired. the vin was not available. the failure and the current mileage was 100,000.

As car was being driven in a parking lot the brakes were suddenly applied as the vsc dashboard light was lite. the car vibrated and slowed in a near stop. brake pedal was nearly useless. the conditions were clear with a dry mostly level pavement. attempted to drive vehicle about one mile to home not knowing if incident would be repeated. however, it was repeated without warning about every 5 to 10 seconds. speed never exceeded about 10 miles per hour. *tr

The vehicle stability control has been engaging when it should not be. while driving at moderate speeds, into a slight turn, the vsc engages for a few seconds slowing down the car. it has been doing this now for the past few months while driving at moderate speeds when it should not be engaging. it is a little disconcerting when this happens being i know that it should not be doing this at that time. *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

Tl* the contact owns 2004 toyota sienna. the contact stated that while attempting to enter a parking space, the vehicle abnormally accelerated and crashed into a concrete wall. the air bags then deployed and the contact sustained injuries to the knee after striking the steering wheel. the manufacturer was not contacted in regards to the failure nor was the vehicle taken to the dealer for diagnosis. the repairs and failure were being handled by the contacts insurance company. the vehicle was towed to an auto repair center. the failure mileage was 25,000.

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 vsc activated at speeds that were at or below the speed limit and in conditions where no realistic possibility of a skd was present. 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. there have been 4 or 5 isolated incidents, but now there has been a serious and dramatic increase in the frequency of the vsc failure. *tr

While parking our 2004 toyota sienna mini van, taking my foot off the accelerator and stepping on the brake pad, the vehicle began to accelerate rapidly. the acceleration was so rapid that the tires squealed as if they were burning rubber. the vehicle stopped when it hit a parked car in front of me. *tr

Tl* the contact owns a 2004 toyota sienna. the contact stated while driving at relatively low speeds of 3 mph and removing her foot from the accelerator pedal, the vehicle abnormally accelerated and proceeded to crash into a cement pole. she suffered injuries to her knees and there was substantial front end damage to the vehicle. the vehicle was towed to the dealer where they repaired the vehicle body damage. the dealer was unable to locate or duplicate the unwarranted acceleration failure. the failure and current mileages were 106,000.

I was driving in the middle lane on a three lane road. i arrived at a traffic light and came to a complete stop. i was standing in a traffic light with my foot on the brake. standing in the same traffic light, there were many cars in front of my vehicle and several cars behind my vehicle. suddenly, i felt my vehicle was attempting to move and smelled burning rubber from the right front tire. at the same time my foot was still applied firmly to the brakes and my vehicle jumped with a great force colliding with the vehicle in front me, which caused another impact and a third impact. the point of impact on my vehicle was the right side of the front of the vehicle. the left front tire was only two weeks oldand the other three tires were approximately 12,000 miles. the two front air bags deployed and the vehicle was totaled. my daughter was in the front passenger seat and suffered a tiny fracture in the rip cage as a result of the airbag impact. this was the first time we had experienced a case of sudden acceleration. *tr

2004 toyota sienna steering problem*cw the consumer stated the dealer fixed the steering problem. however, the consumer had to return the vehicle because the problem resurfaced. the steering was never the same. there were times when the steering would become stiff, but the problem would go away once the vehicle warmed up. the consumer also stated the clip that holds the floor mat in place comes off easily. *jb

3-5-10 at about 11:39am i was making a left turn into a parking space in front of my condominium when my 2004 toyota sienna suddenly lurched forward and jumped the parking stop and hit a cement wall. i tried to brake the car and they did not work. i had new brake pads on 3-1-10 and my car serviced. the car was towed to beachside auto body repair, indian harbour beach, fl 32937. front end damage. we asked that they have a mechanic inspect the car. *tr

I drive a 2004 toyota sienna xle. on 3/4/10 at 1030 am, i was coming to a stop light on broken land pkwy. as i completed a full stop, my sienna tried to accelerate while my foot was depressing the brake pedal. the vehicle lurched but did not stall out and i was able to continue on my way. during the rest of the morning, i did not experience any more acceleration trouble the rest of the day. i did inform my husband and he suggested i research 2004 toyota sienna acceleration. i did that and found a variety of complaints from 2004 toyota sienna owners on several internet auto web sites. *tr

Tl*the contact owns a 2004 toyota sienna. while the contact was driving 5 mph attempting to park into a parking space, the vehicle had suddenly accelerated without warning causing the contact to crash into a nearby gate. no one was injured and a police report was not filed. the vehicle was taken to the dealership where the contact was informed that the vehicle was operating normally. there were no prior warnings. the vin was not available. the current and failure mileages were 12,500.

Sudden unexplained acceleration and brake failure on my 2004 toyota sienna. i was almost at a stop at a traffic light when the light turned green. i pressed the accelerator. my van shot off! it accelerated very rapidly. i pressed the brake. they did not engage. i pressed the brake again. they went to floor. with oncoming traffic on my left and a car in the right lane, i had nowhere to go. i hit the truck in front of me who was stopping at the next traffic light. had i been on a curvy road or the interstate, i could have been seriously injured. i did not look at the speedometer to see how fast the van got. i was too busy trying to find a way not to hit someone. this was very scary. updated 04/22/10 *bf updated 05/10/10 *bf updated ivoq 05/12/10 updated 09/28/10

2004 toyota sienna - erratic rpm in drive, smog stations are not able to do the test, due to alleged car electronics control issue. this is the first ever smog test that was requested by california dmv for this new vehicle after 5-years of use. *tr

I was accelerating away from a traffic light, making a left turn from 1300 east onto ft. union blvd, and the vehicle continued to accelerate rapidly even after i removed my foot from the accelerator. i promptly placed the transmission in neutral, braked rapidly, and narrowly avoided rear-ending the car in front of me. i could not tell if the gas pedal was stuck on the floor mats, but rearranged them quickly and the engine rpms quickly dropped to an idle speed. this was the only time this has occurred. several days later, i took the car to the local toyota dealer, larry miller of murray, ut. i spoke with the manager about the problem, he examined my car, informed me that it was not part of the recall, asserted that there had been no reports of issues with the 2004 sienna, and that the pedal on my car was not of the type implicated in the recalls. he had me take the car to their service department for further inspection and testing. they did not find any failure codes present and no check lights were on. they test drove the car 10 miles, but were unable to replicate the problem. no parts were repaired nor replaced. no further action was taken by them. *tr

Tl*the contact owns a 2004 toyota sienna. the contact was driving approximately 10 mph into the residence garage. the driver applied pressure to the brake pedal, followed by an intended acceleration. suddenly, the vehicle crashed into the garage wall. there were no personal injuries. the license plate was damaged. the vehicle has not been inspected for the malfunction. the vin was unavailable. the failure mileage was 78,000.

Tl* the contact owns a 2004 toyota sienna. the contact stated that the accelerator pedal was stuck down to the floor causing unintended acceleration up to 50 mph. he put the vehicle in neutral and turned off the ignition and kicked the pedal a few times and it resumed the original position. he took the vehicle to the dealership and the vehicle was inspected. he was informed that the dealer could not find anything wrong with the vehicle. the vehicle had not been repaired to-date. the contact had not experienced the failure again up until the time of the complaint. the current mileage was approximately 98,000. the failure mileage was approximately 96,000.

Upon engaging the brake while pulling into a parking spot at our local pizza shop in glenwood springs, co, our toyota sienna accelerated rapidly and hit the brick building 10 feet away. there were no personal injuries but damage to the car and a window in the pizza shop were significant. the car was still going after the crash and if there had not been a brick wall to stop the car i fear what would have happened. the incident was immediately reported to the police and the local toyota dealer. though we love the car we are afraid to drive it anymore, nor are we willing to sell it considering what could happen. we need a proper way to dispose of it. *tr

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. please use this complaint to make an improvement in safety. *tr
