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.
2004 Toyota Sienna acceleration complaints
Page 3 of 5: complaints 41 to 70 of 111, newest first, as owners wrote them.
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.
I was driving into a parking space at approx 10 MPH when the vehicle accelerated while I was parking it. Thank god a tree was in front of the space or I would have hit a person or vehicle. It happened on 9/27/2005 and I was told I must have hit the gas. Since my husband works for a toyota dealership I let it go. I now realize I should report it to you as my husband knows of other accidents since then. The vehicle was a 2004 toyota sienna which was not included in the recall.
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.
Tl*the contact owns a 2004 toyota sienna. While driving at approximately 10 MPH, the contact eased pressure off the accelerator pedal but the vehicle suddenly accelerated. He depressed the brake pedal to prevent the vehicle from crashing into another vehicle in front. The vehicle continued to accelerate until he turned off the ignition. When he restarted the vehicle, it seemed to function normally. The vehicle was taken to an authorized dealership where he was informed that the problem was caused by the floor mat. The VIN was unavailable at the time of the complaint. The current and failure mileages were unknown. Updated 06/25/10.*lj updated 06/29/10.
Ltr fwd fm (wi) re toyota vehicles incidents of sudden unintended acceleration fm owner of a 2004 toyota sienna experienced an incident. *tgw the consumer stated the vehicle accelerated between 95-100 MPH before she was able to shut the vehicle off. She had both feet on the brake, pressing as hard as she could. The dealership suggested it was the foot feed rubbing against the floor mat, but when she looked down at the floor mat, it didn't appear that was the problem.
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.
2004 toyota sienna lurches upon acceleration after braking. After breaking for a turn or any other reason the car will not respond to acceleration and then lurch or accelerate quickly. I was told by toyota that this was a electronic function of the car and it is normal. This is not normal and will lead to transmission repairs or an accident. This occurs all the time and has not been repaired.
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.
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? My sienna is still having the same problem not able to accelerate and jerks when it does get going. This is our 4th toyota and we have never had any trouble. In all my years as l loyal toyota customer I find this very sad. Thank you
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.

After changing the front brake pads on our 2004 toyota sienna sometime early 2009 and while it was propped up on metal ramp, my daughter placed the transmission in reverse applied some gas, it instantly took off at a high speed in reverse. The car traveled approx 40 feet backing into a ditch which at that time it stopped possibly because of the sudden abrupt ditch. I her father was watching and asked "what did you do" she stated "nothing it just took off" this was a year before I heard of the toyota problems so I just shrugged it off as a weird incident. Now hearing other incidences I suddenly remembered my incident. I only report it now because it may help with any investigation as to what the problem is. I have not yet heard of the accelerating problem happening in reverse like it happened to me.
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

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.
Tl*the contact owns a 2004 toyota sienna. While driving with the cruise control engaged and the vehicle accelerated beyond the set speed.

I drove a 2004 toyota sienna. My car is not part of the recall. However, I had an incident similar to the gas acceleration. This incident happened last year, where I was in mcdonald parking lot. I took my foot off the gas pedal to slow down in order to park, suddenly the car accelerated (about 20 MPH) and I had to step on the brake but the car did not slow down. I had to step on the brake the second time for the car to stop. This incident last only a few seconds. I did not have any more incident after that one.
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.
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.
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.
1. Toyota sienna ce driver's door welded part (inside door) snap off causing loud thud sound when opening & closing the door. I found out in the internet that before there was a lot of complaints about it but toyota did not order a recall & now they want me fix it in a shop at my own expense. 2. Sudden acceleration from idling during traffic cruising.

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.
I suspect the cruise control of my 2004 minivan toyota sienna ce has similar issue found in recent prius reports. 1. When cruise control is used on uphill road conditions 2. 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. After reading similar complaints on prius of toyota, I feel this may be the same issue.
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.
