TIRES:TEMPORARY/EMERGENCY SPARE TIRE
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2004-2011 Sienna vehicles originally sold in, or currently registered in, Connecticut, Delaware, Illinois, Indiana, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, Wisconsin and the District of Columbia. The affected vehicles have a spare tire carrier assembly mounted under the vehicle whose attachment cable may corrode due to high concentrations of road salt splashing onto the spare tire carrier.
Remedy: Toyota sent owners in August 2014 an interim notification to advise owners of the recall and that dealers will perform an interim remedy to remove the spare tire and relocate it to the luggage compartment, free of charge. Owners are being mailed a second letter as parts become available and dealers will replace the spare tire carrier assembly with an improved one, free of charge. The remedy campaign is being performed in phases. The first phase of the recall began July 7, 2015. Owners may contact Toyota customer service at 1-800-331-4331. NOTE: 2004-2010 Siennas subject to this recall were subject to recall campaign 10V-160 initiated in 2010. Those owners are advised that they must have their vehicles remedied again under this campaign and that having the earlier recall completed did not remedy their vehicles. Additionally, model year 1998-2003 Siennas were recalled as part of safety recall 10V-160. Owners of those vehicles that have not had not the remedy performed on their vehicles, should contact their Toyota dealer to schedule a free repair.

STEERING May 9, 2025
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.

STEERING Feb 11, 2025
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.

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.

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.

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.

TIRES Aug 13, 2021
P225/60R17 98T: Tires create vibrations in the steering column. One tire in particular creates severe vibrations that mechanic states could lead to problems with the steering components. Mechanic http://www.japaneseautorepair.org/ e-mail [email protected] (John). Coordinated w/ Sandy Boulevard Line up shop and one tire could not be aligned due to defect. 2004 Sienna van (140,900 odometer miles) is equipped with Toyo Observe GSi-5 195/65R15 91T (separate 16" rims purchased from Les Schwab) and there is no vibration at all. Les Schwab last tried to "balance" the defective tire in 2019. I have about the 4rth appointment Aug 21 2021 @ 9AM. I will also take the 2004 Sienna van to Japanese Auto repair (web site and e-mail above). to look for any defects. I probably need to put the Winter Observe GSi-5 tires on the car for safety, but they wear out quickly on summer hot roads.

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
