While parking, accelerating no more than 5 MPH vehicle surged forward. Although I was applying the brake, the car would not stop until it ran into a tree trunk. I will be making an appointment with oakbrook toyota in westmont, il to replace the broken foglight that occurred during the collison as well as research the problem and hopefully apply a fix.
2004 Toyota Sienna acceleration complaints

I noticed an article recently about a probe into toyota's (camry and lexus) that surge. My 2004 toyota sienna surges forward when braking and though it does not do this consistently, it happens every so often and could potentially cause an accident. I have reported this to the dealer and they have examined the vehicle and said that there is nothing wrong. My personal experience with the electronic throttle control is that not only does it surge when braking, there is also a delay in the signal when accelerating that either causes an unsafe delay in entering into traffic and can also cause the vehicle to "peel out" from a stopped position. I basically feel unsafe in this vehicle, yet my concerns voiced to the dealer have been dismissed. This defect needs to be seriously monitored in siennas as well as other toyotas with the electronic throttle control.
Engine idles very fast in cold weather first few minutes. While driving a block to the first stop sign has to apply the brakes very forcefully to get the car to stop. This causes some loss of control , especially on a slight down hill slope during snowy/icy weather. Appears to be combination idle, and the automatic transmission.
Vehicle hesitates/fails to move forward in the following mode: after braking, when the vehicle is still moving between 5 to 15 MPH, the van does not respond to accelerator pedal input; vehicle hesitates with no movement forward, then shifts hard into first gear and lurches forward. We have had 2 close calls, waiting for the vehicle to respond to accelerator pedal input. Also, accelerator pedal has a dead spot. The first half inch of pedal causes no response from vehicle). This "dead spot" along with the hesitation noted above can result in a 2 second response failure from the vehicle. This situation has put my family in harms way on numerous occasions.
I ran into a big problem with my 4 month old 2004 toyota sienna xle. I was turning onto a hill and wanted to see how it would accelerate up the hill so I floored it. The car accelerated well and I took my foot off the gas pedal at about 35 MPH. The problem was that the car kept going at full acceleration. There was no one in front of me so I started trying to figure out how to stop it instead of just turning off the car (I needed to get to the top of the hill and I could coast to where I was going). I put it into neutral but all it did was rev to 6000 RPM, I checked to make sure I somehow hadn't gotten the cruise control on and I hadn't, I downshifted into 3rd and kept pressing on and letting off the brake pedal since I didn't want ruin my breaks (I was able to keep the speed between 40 and 50). As I neared the top of the hill (it is about 1/3 of a mile long) I figured I would turn the car off at the top. Just as I was about to crest the hill, the van stopped accelerating as the car leveled out and then ran normal. There is an initial level portion going to the top of the hill and the van did not stop accelerating at the level spot. It wasn't until the second level spot that it stopped accelerating..
When driving at an undetermined speed vehicle surged. Consumer took the vehicle back to the dealership for inspection.
Recurring drivability problem with 2004 sienna xle 3.3l. After decelerating then reapplying throttle, surge varies from annoying to dangerous. On occasion, is severe enough to squeal tires. From a dead stop, throttle response is better but from a rolling stop, dangerous and inconsistent.
Distances between the gas and brake pedals were designed poorly. The pedal pad was 2x4 inches. When transferring feet from one pedal to another consumer's foot would get stuck between the pedals.
While parking, the vehicle surged forward. As a result the vehicle collided into a fence. The dealer stated they were unable to duplicate the problem. Please provide additional information.
2004, toyota sienna xle limited. Very sluggish throttle response when cruising, apparently due to very sluggish automatic transmission down shift. No problem when accelerating from a stop. Problem is bad enough to cause an accident when the driver expects reasonable throttle response to avoid a collision , such as crossing an intersection.
When cruise control is engaged while driving uphill vehicle runs out of control, brake pedal needs to be depressed to stop vehicle.
