problem #49

  • 100,000 miles


When driving through sweeping turns on dry, paved roads, the vehicle's vsc engages, causing vehicle to self brake, pulling to the left (toward oncoming traffic), and the vsc light on the dash to blink and beep. This puts the passengers of my car in danger, as well as those in vehicles around us who are not expecting a sudden application of brakes or swerving into neighboring lane. My vehicle has been inspected at an independent mechanic with no findings which would warrant the vehicle to engage in such activity.

I was backing out of my garage and I have an L shaped driveway. I was going approx. 2mph and then I took my foot off the gas and was "covering" the brake and suddenly the car began to accelerate and I tried to brake, but the car slammed into a parked car and still did not stop. It continued to accelerate until I ended up in the street. I was trying to brake the entire time, but the car did not stop and continued to accelerate. My foot was not on the gas. We live on a residential street in the suburbs and luckily no one was hurt. The Sienna and the parked car both have extensive body damage.

2005 Toyota Sienna's vehicle stability control engaged for no reason while in many different conditions (dry, wet, curve, straight, it didn't matter) making me lose control of the car. The vsc, trac off and check engine lights came on and a beeping sound engaged while the care took over not allowing driver input. I had to put it in neutral until it turned off. I have read many accounts online of other Toyota Sienna drivers experiencing the same dangerous problem. Thank goodness when it has happened, I haven't had a truck or semi next to me. This is my family car in which I need to drive my kids and other people's kids, and I cannot drive it anymore. Toyota has to fix this problem, since it is a manufacturer problem.

Sienna 6-cyl

  • 106,000 miles
On Monday, Oct. 13, 2014, I was slowly backing out of my driveway when my 2005 Toyota Sienna van suddenly accelerated rapidly and uncontrollably. I tried to stop the van, but it sped backwards across the street in front of my house, ran over a curb, and crashed into a parked car. The car that my van struck pushed into another car which was also damaged. This was most frightening and upsetting, especially since I have learned that this type of malfunction has been reported many times to Toyota. My van was totaled, the second car may have been totaled and the third car will need at least a new door. A woman who was in the third car is claiming to have been injured.

On hwy 1 from pacifica to santa cruz, driving approx, 45-50mph around the bends and curves, the van's vsc light would come on along with warning beeping and the car would try to "correct" itself by steering straight when I needed it not to. This happened again approx. 1-2 months later while driving along hwy 50, at approx. 45-50mph up to South lake Tahoe on the same dry, but winding/curvy roads, the car would try to "correct" itself by steering straight. Again, on June 17th, along hwy 50 approx. 45-50mph just taking the exit off of the freeway, steering into the right hand turn lane, the car vsc light, beeping and steering "correction". this is very dangerous!!!! I am surprised that it has not caused an accident yet!. I need the car to turn for a reason!! please feel free to contact me for further information. I took it to the Toyota dealership and they said that the van had no logs from the sensors (steering angle or yaw). We asked them to recalibrate it (set it back to zero), but that obviously hasn't worked. I have ordered a new steering angle sensor and I am having it installed and the system recalibrated, in hopes that will fix the issue.

Driving 45 to 50 mph on a road on a dry sunny day. Suddenly vsc light came on and warning beep and at the same time the brakes engaged causing a rapid slow down of the van. I almost swerved into the next lane due to the brakes engaging. This happened 3 times in one morning. This is extremely dangerous as it could cause a collision, especially at higher speeds.

The accelerator stuck on this van as I was passing another vehicle on a rural, two lane road. As soon as I depressed the accelerator to pass, I knew something was wrong. The gas pedal stayed down even after I removed my foot and the van continued to accelerate even faster even though I was now hitting the brakes hard! with curves in the road approaching in about a mile, I had to do something fast! I was standing on the brakes with both feet now and the van continued to speed up. I was able to shift it into neutral, all the while continuing to stand on the brakes. The engine revved even faster but I was able to get the van turned off the road into a farm field access drive. The van still wasn't stopping but at least I was off the road and not going to hit another vehicle. As the van continued to move, I thought about bailing out but thankfully, I didn't. the van was still going fast enough it could've run over me and I had no idea where it would end up if I got out! by the grace of god, the van finally stopped after I started turning the wheel hard to the left. I shifted it into park and shut it off while I sat there shaking and trying to decide who to call first. This situation could have turned out extremely bad had the circumstances been different. Thank god there was no one in front of me while this was going on, I wasn't in a congested area of houses or other vehicles or on a busy highway. I'm so glad one of our boys wasn't driving this when it happened! this was the scariest thing that's ever happened to me while driving over 30 years! the van was towed to the dealership where we purchased it and have had it serviced faithfully. I'm waiting to hear back from them when they will be able to look at it.

2005 Sienna was driven to a parking garage and parked for two hours. Upon returning to the Sienna and starting the engine, three lights came on; check engine, vsc, and trac off. Drove vehicle home (150 miles), the 3 lights remained on as well as loss of cruise control and an intermittent compass display. Took vehicle in for inspection at a local Toyota dealer and was told the skid control unit ECU needed to be replaced. I found out there are other complaints and a technical service bulletin on the 2005 Sienna vehicle stability control (also called electronic stability control) system that has caused injuries. Even more remarkable, my 2005 Sienna has only 62K miles and in that time there has been 2 other incidences with the same symptoms. Why has there not been a recall if there are already injuries in the database??

During the turning of the steering wheel to the left at 5-10 mph, in making a left turn, clicks and clunking noise could be heard and felt through the steering wheel. At one point, I had to apply bigger turning force to the left as if I was overcoming some unusual resistance in the steering column, making the turn uneasy and non-smooth.

Sienna 6-cyl

  • 92,000 miles
Our 2005 Toyota Sienna took off on us in rush hour traffic. Moving my foot to the brake and my husband shifting into neutral was the first thing we tried, we also tried park and reverse, and turning off the cruise control, none of which worked. The Toyota Sienna death trap continued to accelerate rapidly even though my foot was jammed on the brake (I didn't remove my foot from the brake for another 2 1/2 hrs until the tow truck pulled in front of us. By the way, when your vehicle is suddenly traveling much, much faster than anyone else's vehicle on the road, it's all you can do to not hit someone. Believe me, I was suddenly swerving in and out of the lanes and cutting everyone off. The only thing that stopped our Toyota death trap was pulling the key from the ignition, certainly not ideal in rush hour traffic. While this was going on, our son was in the backseat calling 911, while our daughter cried. We don't have a lawyer and Toyota won't fix our van. What are we supposed to do with it?

Sienna 6-cyl

  • 53,978 miles
I had a sudden acceleration incident in my 2005 Toyota Sienna. I was making a slow U-turn in front of my home into a parking space by the curb on the far side of the street. The width of the street is such that even with the steering wheel turned fully to the left, the passenger tire rises up a driveway incline just before the car is 180 degrees around. As I usually do for this turn, I need to turn slightly more than 180 degrees, have the passenger tire come out of the driveway, then turn back to be parallel to the curb. I had slightly misjudged the turn this time, and realized that my passenger tire was going to have to drop an inch or two off the rising curb at the edge of the driveway. Because of this I am certain I had my foot on the brake pedal to keep my speed down. About 5 feet before the wheel was going to come off the curb, the car lurched forward, jumped the curb violently and fast, and continued my turn carrying me partly back into the street. I was very surprised, but brought the car to a stop quickly with the brake. The engine was no longer revving once I stopped. I estimate tat the acceleration lasted for not more than 2 seconds, possibly only 1 second. I reversed the car and then drove it forward into my intended parking space. After putting the shifter into P, I revved the engine and everything seemed fine. Fortunately, there was no accident and no damage I am aware of (although the passenger wheel did make a thump as it came over the curb).
