general problems of the 2004 Toyota Sienna

Unknown.

I have a problem at shift solenoid e make my car jump and not safe when park.

Knock sensor and vsc are malefunctioning.

The outside temperature was below 32 and it was close to 25 or so. When I was driving the car at 40 mph with engine temp still slightly above cold(not at optimal which is almost half way) and slowed down by using gentle brakes(not hard brakes). Just before the vehicle comes to a full stop, there is unintended acceleration and I could see even the rpm(scale) to spike temporarily. This has been happening every time when outside temp is cold and vehicle is driven with cold or slightly above cold engine temperature. There is a risk of hitting another vehicle or meeting accident if misjudge my braking because of this problem. . Please note : this problem disappears when engine temperate is at optimal and I have driving a Honda accord 2008 exl for last 7 years(was bought new one), I never had experienced this problem in that car even when driven with cold engine.

Tl-the contact owns a 2004 Toyota Sienna. The contact stated that while attempting to back the vehicle out of her garage, she put the vehicle in rear drive and accelerated, but the vehicle went forward. The contact put her foot on the break and, applied the parking brake, and turned the vehicle off. After eight hours the contact attempted to restart the vehicle. The vehicle would not restart and was stuck in second gear even though the instrument panel read that the vehicle was in park position. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 160,000. Cs.

I was driving my van when I noticed the a/c was not blowing cold air, it was more cool than cold. Then it would blow hot air on occasion then it would eventually blow cold air again. Eventually the air wasnt cold at all and it would constantly blow hot air. This was very unconfortable due to the fact that it was summer and I live in florida. I took it to a mechanic and he told me it was the compressor, so I had it replaced. The ac was blowing cold again, this lasted for about 12 months. The same issue started to happen again. First cool air then on and off hot air and now nothing but hot air. I took it back to my mechanic and he told me it might be the relays, I replaced both of the relays and the air is still not cold. I then found out that it was the compressor again. I cannot afford to replace the compressor and im afraid to replace it if the problem will just continue. I feel a recall for the faulty part is in store. I am aware the vehicle itself is a few years old but my other vehicle is a 99 and I have no problems with the ac other than I have to turn it off at times because its too cold. Ive gone to online forums and read up on the 2004 Toyota Siennas and found out that I am not the only one with an ac problem. This problem is with many more vans.

The sliding automatic door on my 2003 Toyota Sienna frequently closes without warning and several times it has closed on my daughter. It is suppose to have a sensor that would prevent it from completely closing if something or someone is in the way but it doesn't work. I've had to pull my daugher way from the door as it was pressing against her. This is a real safety concern. The van has also recently begun to "automatically" lock without warning.

When negotiating moving into traffic at slow speeds, when a small amount of accelerator movement is made the vehicle rapidly accelerates making it necessary to quickly apply the brakes to avoid collision. The vehicle was purchased used from a dealer and there was a recall bulletin (tech service bulletin issued 11/7/2003 for 04-05 Sienna bulletin no tc007-03 out on the engine control module. When pointed out to the dealer they simply stated that that recall was only available to the original purchaser and then only if reported within the first three months after purchase. Was told by two dealers that the recall did not apply to our vehicle and later that a recall was not issued for that problem. ( I have a copy of the origional recall notice stating the above problem).

2004 Toyota Sienna le. Vehicle hesitates when acceleration. There is a big delay before the car gains speed. This is a on going problem. Dealer states that the car was made that way and there is nothing that they can do to correct the problem. This hesitation can cause an accident at any time.

While at a stop vehicle hesitated before accelerating. Dealership was notified, but did not resolve the problem.

Hesitation, bogs on a acceleration, delay in a acceleration no power for a few seconds. Looses speed and cars behind catch up very quickly and worried about getting hit in rear end. My wife refuses to drive and had to pull off road twice to avoid rear end collision. Toyota dealer felt the problem, but I have no offer for repairs.
