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.

Sudden loss of power by model year
What owners say
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.
Driving along on 210 freeway east bound in pasadena doing 60, the traction control kicked in, the van braked, and the traction control light on dashboard came on with a beeping sound, and the steering wheel shuttered and car lost power. Lasted about 5 seconds and then back to normal. Could have been rear-ended or could have swerved into other lanes. Also happened on 110 fwy northbound in pasadena, 60 MPH, on slight turn, same thing happened, traction control kicked in, the van braked, and the traction control light on dashboard came on with a beeping sound, and the steering wheel shuttered and car lost power. I came close to hitting fwy divider and swerving into car in adjacent lane. Roads were dry and no slippage of wheels felt. Took it to dealer wondries toyota in alhamba,ca twice and were unable to duplicate.
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.
Loss of power to steering wheel making it difficult to turn corners, park, etc.

I have a 2004 toyota sienna with approximately 60,000 miles. The steering seems to have lost power steering capabilities as well as over turning when going around curves and corners.
I have a 2004 toyota sienna, with only 70,000 miles. I suddenly and intermittently lost power steering. It was not total loss--that I could have handled, but it would come and go, even within a single turn. When I turned the wheel, I could not predict how the car would respond. No accident, fortunately, but a couple of close calls. I drove immediately to a t dealer, and they diagnosed a failed u joint and replaced it today. There had been no prior signs of u joint failure. I wanted to submit this in case others are experiencing similar issues. Otherwise, I just consider it an isolated case. Thanks.
Loss of power steering due to internal leak of fluid into rack. Made high pitched squeaking noise and fluid would slowly leak (internal, could not find external leak) first occurred around 11/08 and repaired first under warranty on 3/09 at 34,749 miles. Now has occurred again at 80,000 miles .
Approximately 20 months ago, began experiencing very difficult steering. Steering acted as if loss of power steering. Difficult to turn and would not return to neutral always, especially in cold weather. Near accident when steering would not return to neutral as expected. Last summer, steering improved in warm weather. This winter, constant problem and did not go away with return of warm weather. From what I have seen on this website, very common and expensive problem.
Steering binding or increased steering effort on toyota 2004 sienna. Steering requires extra effort while turning, and does not always return by itself (requires effort to return to 0 degrees). This condition varies (different effort at different points in the turning arc) from turn to turn, making it a hazard for driving. It is similar to partial loss of power steering midway through a turn. Seems to be getting worse. I understand there is a tsb to fix this problem, which I am trying to obtain so the problem can get fixed correctly. (don't want to be overcharged for unnecessary work).
Tl*the contact owns a 2004 toyota sienna. When turning a corner at approximately 5-10 MPH the vehicle would hesitate and lose power. The dealer stated that the vehicle needed a computer update, however; the system was unavailable. The dealer stated that the failure was not normal. The current mileage was 100,000. The failure mileage was unavailable.

- What is wrong
- Toyota is recalling certain model year 2004 avalon vehicles; 2004 and 2005 camry, camry solara, highlander, and sienna vehicles, 2006 highlander hybrid; 2004 and 2005 lexus es330 and rx330; and 2006 lexus rx400h vehicles manufactured from june 1, 2004 through march 31, 2005, equipped with the 1mz-fe or 3mz-fe engine. The amount of adhesive agent applied between the outer ring and the torsional rubber damper (inner ring) in the crankshaft pulley may be inadequate. If the adhesive is insufficient, there is a possibility that the outer ring may become misaligned and it may not properly rotate with the inner ring, causing noise and/or illumination of the battery discharge indicator light.
- Risk
- In some cases, the belt for the power steering pump may become detached from the pulley which could result in a loss of power steering and a sudden increase in steering effort, increasing the risk of a crash.
- Remedy
- Toyota will notify owners, and dealers will check the crankshaft pulley to identify whether it was produced by the u.s. Supplier. If so, the dealer will replace the pulley with a new one at no charge. The safety recall is expected to begin during early january 2012. Owners may contact toyota at 1‑800‑331‑4331.
