I have a 2006 Toyota Sienna le minivan. A month after the purchase I noticed that the transmission did not shift correctly. The transmission gets stuck often and very often will run in 2nd and 3rd gear for extended times. When the van manages to get out of 2nd or 3rd it clunks into 4th. I have taken the van to the Toyota dealership 5 times to get it looked at and everytime they tell me there is nothing wrong with the vehicle. The dealership says because they can not duplicate the issue in the shop it must not exist. They will not fix it and they will not take it back. I feel unsafe driving the van because sometimes it will not drive- it simply just wont go because it hesitates to go into the next gear. I don't feel safe to pull out in front of other vehicles because I don't know if it is going to stick or not. The initial problem happened in Nov. 2008 only a month after purchasing the van. This is an ongoing problem and it is getting much worse.

2006 Toyota Sienna surge and deceleration while driving. Seems the vehicle can't decide which gear to go in. The consumer stated the transmission would shift late at times.
The automatic transmission on my 2006 Toyota Sienna causes the engine to race when trying to shift to a lower gear at slow speeds.
Vehicle surges while gently applying accelerator and can't decide which gear to be in. Transmission appears to hesitate, especially noticeable at 5-10 pmh and while turning. Dealership says its completely normal. The drive-by-wire system cannot react quick enough to changes in acceleration. After days of research I see this is occurring on avalon, camry, Lexus es300-330, highlander, BMW,Audi, vw touareg, Subaru. . . Shall I keep looking. Obviously the drive by wire technology is not mature and dangerous. Re-programming is needed. To date there are no TSB's for the 04-06 Sienna's regarding this issue. 8jb.
The contact owns a 2006 Toyota Sienna. The driver stated that while driving 10 mph in an attempt to increase speed, the vehicle began to hesitate and surge. The dealer stated that there was nothing they could do to assist him since the failure was electrical which was also a normal function of the vehicle. The failure mileage was 10 and the current mileage was 75,000. The consumer stated when slowing down between 5- 10 mph and then speeding back up again, the van would hesitate and then surge forward to the point of jerking the consumers neck. The vehicle would slow down once the accelerator was released. Also, the drivers side door was exhibiting a popping/scrapping noise when it was being opened or closed. The consumer took the vehicle to the dealer and was informed there was a recall regarding the thinness of metal which allowed the cracking of the metal where the door stop was attached to the door.
