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.

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. The only way to stop the rapid acceleration and deceleration is to press the brake in order to disengage the cruise control system. 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.

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.

Failure of the adaptive cruise control module on a 2004 Toyota Sienna xle limited. The adaptive cruise control module, located under the front bumper on the passenger side, fails completely and continuously resulting in complete failure of the cruise control system. The module is not sealed properly thereby allowing moisture inside resulting in corrosion and failure of the part. When actuated, the part is designed to automatically slow the vehicle while approaching slower traffic from behind. Failure of this part while driving could result in an accident if the module does not automatically slow the vehicle properly. The vehicle in question has only 85,000 miles on it. The vehicle has 88,000 miles on it know. The vehicle was taken to kelso Toyota in appleton, wi where I was told that the unit need to be replaced. I disassembled the unit and found the corrosion. I believe the deal would simply replace the unit with new and then discard the old unit not knowing why it failed. I believe the wrong oring material was used. I believe in cold weather the oring shrinks allowing water into the modules cabinet resulting in the failure.

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. Whenever I reached more than 6mph, vsc activated and broke the speed down to 5 mph. I could only drive at 5mph without getting vsc activated. Had to get a fairfax city police escort to the nearest Toyota dealer. This is definitely a safety hazard and with all the occurrences of reports found on the internet, Toyota should be requested to issue a recall for repair. I understand this has been a problem with other Toyota vehicles. See rav4faq.kerkerinck.de/XA2/tsb/files/cp4010_0_1_vsc_stoerung.pdf.

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.

I had slowed my car to allow a group to pass and was making a left hand turn into a parking spot. My car lurched forward and sped forward nearly striking a group of teenagers. I plowed through three cement pillars and a flower pot and finally came to rest. My engine was revving and my foot was on the brake.

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.
