New Car Assessment Program

The 2004TOYOTASIENNA carries 2588 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 56 crashes, 12 fires, 200 injuries, and 2 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.

Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2004 SIENNA is structure:body:door with 354 filings, followed by structure:body (281) and latches/locks/linkages (228). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 10 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.

NHTSA currently has 51 investigation files overlapping the 2004 SIENNA, and 1 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

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.

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.

20250109FUEL/PROPULSION SYSTEM

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.

The contact owns a 2004 Toyota Sienna. The contact stated that while driving approximately 65 MPH the vehicle suddenly experienced unintended acceleration and the speed of the vehicle increased to over 90 MPH. During the failure, the braking system had failed and would not stop the vehicle while pressing the brake pedal. The front passenger was able to view the fuel pedal was stuck to the floor and was able to physically pull the fuel pedal up from the stuck position and the vehicle's speed was reduced. The incident lasted for approximately 10 minutes. During the incident, the police were on the scene. A police report was later filed at the scene and the vehicle was towed to the local dealer. The contact was informed by the dealer that the failure was due to a missing fuel pedal pen. No further information was available. The manufacturer was notified of the failure.
