#1 - Automatic Transmission problem of the 2008 Toyota Sienna
The vehicle involved is a 2008 Toyota Sienna. My 2008 Sienna hesitates when gas pedal is pressed after slowing down. The engine revs fast (engine is loud) but car does not respond accordingly by moving ahead until a couple of seconds later. Usually I would release the gas pedal to prevent the engine rev from going very high. This happens intermittently. Dealer could not replicate the problem and service manager explained that was probably caused by a delay in trying to get the correct shift. There was no TSB on the problem according to the manager. This problem occurred on July 13, 2011.

#5 - Automatic Transmission problem of the 2009 Toyota Sienna
The car involved is a 2009 Toyota Sienna. Crash was involved with the Toyota Sienna. Our 2009 Sienna may have had a sudden acceleration problem. When the car was put into reverse, a sudden acceleration sent it down our driveway. Situation: pulling into the carport, which involves a 90 degree turn at the top of a short (10m) steep narrow walled easement, the driver of the Sienna could not make the turn in one motion and was required to put the Sienna in reverse at which time the minivan suddenly accelerated, squealing its wheels. The result was a 5m careen down the driveway. The result was about $4,000 body damage, but no injury to the driver or my 2yr old daughter - although all were shaken. We have since got rid of the car - traded it for a 2010 highlander. This automatic transmission problem happened on November 17, 2009.

#6 - Automatic Transmission problem of the 2008 Toyota Sienna
The car involved was a 2008 Toyota Sienna. The VIN of the car is 5TDZK23C58_. Unintended acceleration incident. Car was driven 200 miles the previous night and garaged. The next morning, car was started, backed out of driveway, and driven 15 mph for 1/4 mile until on main road. After traveling 0. 4 miles on main road I slowed to a red light. The engine started racing (but not red-lining). I am absolutely sure my foot was not on the accelerator pedal. I shifted into neutral, which removed the forward pressure, and after a second or two, the rpms drifted back into the normal range. This is the most recent occurrence. Other instances have been less severe and have all occurred while braking the vehicle. This issue happened on 11/01/2009.
#7 - Automatic Transmission problem of the 2008 Toyota Sienna
The car involved is a 2008 Toyota Sienna. The vehicle identification number (VIN) is 5TDZK23C58_. Problem occurs after slowing down at a stop sign or intersection at the speed between 5 to 10 mph and then go to increase speed. The transmission hesitates. One time the engine seemed to roar up, but the car didn't move. . . . This hesitation occurs when transmission is shifting at low speeds when accelerating after slowing down at an intersection or turning at a corner. This occurs intermittently but is quite noticeable. I can often reproduce hesitation with a hard brake followed by heavy throttle. It was Sat., Oct. 31, 2009 when this automatic transmission issue happened.
#8 - Automatic Transmission problem of the 2008 Toyota Sienna
The VIN of this Sienna is 5TDZK22C88_. There was crash involved with this Toyota Sienna. 2008 Toyota Sienna. It was Thursday, August 20, 2009 when this automatic transmission issue happened.
#9 - Automatic Transmission problem of the 2008 Toyota Sienna
2008 Toyota Sienna acceleration hesitation this minivan hesitates from driver acceleration for 1-2 seconds intermittently at very low speeds. However, the problem can be reproduced very easily by making a corner turn at low speed, and increasing acceleration after the turn. The minivan will not respond for 1-2 seconds before 'jumping' into the acceleration. The biggest safety issue with this is a left turn across an oncoming lane of traffic (similar to a corner turn). If I am coasting to the intersection for the turn, the minivan does not respond to the driver input for acceleration to get out of the way of the oncoming car (until through the intersection). Knowing this defect, I compensate for it, but an unsuspecting driver could have an accident with this defect. It was Wednesday, April 28, 2010 when this automatic transmission issue occurred.
#10 - Automatic Transmission problem of the 2008 Toyota Sienna
The vehicle involved is a 2008 Toyota Sienna. The vehicle's vehicle identification number (VIN) was 5TDZK23C68_. The transmission does not respond to get the car into the first or lowest gear when pressing on accelerator if you do not come to a complete full stop at an intersection. It also appears that prior braking or slowing the vehicle as you come to a stop affects how the car shifts into gears and could be why it hesitates or hangs in no gear while trying to accelerate through an intersection or stop. This problem occurs at least 90% of the time. The response from the transmission while accelerating in these situations warrants a replacement or adjustment. This issue happened on Jun. 14, 2010.
#11 - Automatic Transmission problem of the 2008 Toyota Sienna
The vehicle involved was a 2008 Toyota Sienna. Crash happened when the problem occurred. VIN of the vehicle was 5TDZK22C98_. Pulled into parking space and vehicle suddenly accelerated and hopped onto curb and ran into pillar at a restaurant. Luckily nobody was eating on the sidewalk where van ended up. Placed vehicle into park and removed foot from brake and vehicle continued to lunge forward. Immediately hit brakes again and a bystander came to determine what was wrong. Talking to bystander to determine what happened, I took my foot off brake again and vehicle lunged forward (while still in park). Decided to shut vehicle off and have it towed to a dealership. I am awaiting a call from Toyota customer experience center to setup an inspection, however I went to dealership to pick up some things out of the car. I instructed the service agent that the van was not to be driven until the Toyota customer experience center inspector had a chance to look at the van with all parties. Next thing I know the service agent had pulled the van into the service bay for me to grab my belongings out of. I hope this did not ruin any data in the computer about what happened in the parking lot. This automatic transmission issue occurred Jul. 22, 2010.
#12 - Automatic Transmission problem of the 2008 Toyota Sienna
The car is a 2008 Toyota Sienna. The vehicle's vehicle identification number (VIN) is 5TDZK23C58_. Upon accelerating between first and second gear (7-15) miles an hour, especially after breaking, the vehicle hesitates as if it was in neutral. The rpm's go up but the car does not move. This mainly happens when making a right hand turn when not fully stopping. I also have had it happen when making a left hand turn going across traffic trying to get across the intersection. I have taken this vehicle in numerous times and the problem has never been reproduced by the service tech. I have taken them out on a drive along only to not reproduce it also. This is my main vehicle I drive my four children around in and I would hate to have this issue occur when I really need to accelerate and cause an accident. Apparently, I am not the only individual who owns this vehicle that had witnessed this hesitation problem. I believe this problem warrants further investigation and a possible recall/fix. This happens almost ever time I drive this vehicle. It was Friday, December 31, 2010 when this automatic transmission issue occurred.

#16 - Automatic Transmission problem of the 2007 Toyota Sienna
Crash happened when the problem occurred. On August 11, 2007, my family experienced a head on collision. We were driving a 2007 Toyota Sienna. My husband was driving and died at the scene. The investigation never found any reason for the cause of the accident. My husband crossed the center line while going round a slight curve. He was 47, poor weather was not issue. If the accelerator on the Sienna malfunctioned and did not respond, that could definitely have been a factor. Our van had less than 3000 miles on it. We purchased in may 11, 2007. The autopsy for my husband came back negative for any medical condition concern. Please investigate our accident report and be sure the safety and reliability of Sienna's is sound.

#17 - Automatic Transmission problem of the 2007 Toyota Sienna
Purchase a 2007 Toyota Sienna minivan in December 2007 with almost 20,000 mile in it. After purchase notice that when engine is cold it sounds like a diesel engine until it warms up. Also notice what feels like a slip in the transmission in lower gear. This happens if following behind someone and they turn u need to slow down. When u accelerate to get back up to speed there is a delay or a slip before transmission engages, complained with the local dealer (andy mohr Toyota) where purchase from. We have complained since day one of ownership. Toyota dealership states that the vehicle has a memory transmission and learns your driving habits. Well me and my wife don't drive the same and neither does anyone else. No people drive the same and why would someone make a vehicle like this. They also stated that there is no fix at this time. Just trying to blow me off. As for the engine slap when cold they told me it was the exhaust heating up. Now I am no mechanic but let me tell you that is not an exhaust clapping up while heating. Called Toyota USA and file a complaint after a year being pissed at what we spent and how unhappy we were. They set up a third party arbitration and a person from Toyota. We met at the dealership and I voiced my concerns. We even went on a test drive so I could show them what it did. What a joke that was. The person from Toyota explained to me the vehicle was doing exactly what it should be doing. ( the delay in the transmission to me seems to be another Toyota problem that they don't want to acknowledge and im just crazy. ) I have never owned a vehicle that did this. I guess we will need for some people to get rearended and killed before something is done about it. Nothing came out of it and now we are stuck with this expensive van that's a heap. Purchased Toyota for there reputation and what a joke. Never again will I do this. I will sure research before I purchase my next vehicle. Toyota's a joke don't buy!!. This automatic transmission issue occurred Sun., Mar. 1, 2009.
#18 - Automatic Transmission problem of the 2007 Toyota Sienna
The car involved was a 2007 Toyota Sienna. The transmission was doing what felt like "neutral drops" at low speeds, where I would shift into drive, get the "clunk" that I normally associate with the transmission dropping into first, then depress the gas slightly to start moving. The problem is that the engine would rev suddenly, and then catch first, which as you know, causes a sudden lurch of the entire vehicle since the engine had been revving just before it caught. It would also occasionally just "lose" the gear while driving at low speeds. On 6/12/2010 the transmission went out on me while I was driving home (with my family) on the fwy (north 5) from legoland. I have to across 5 lanes to get to the shoulder. I got the van brand new on 3/28/2007 (w/only3 miles on the van) from carson Toyota, CA. . . I paid $28000 w/package3 (out the door price). . . As of 6/12/2010 the van has under 14,000miles. The Toyota dealer replaced the transmission with no charge (still under powertrain warranty). Transmissions aren't supposed to go out that quickly, it definitely seems to be a quality control issue. Under 14,000 miles there has been no service due so it's not a matter of missing scheduled maintenance. This is obviously a very valid safety concern. The failure date was 06/12/2010.
#19 - Automatic Transmission problem of the 2006 Toyota Sienna
The vehicle having this issue was a 2006 Toyota Sienna. 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. It was Wednesday, Sep. 6, 2006 when this automatic transmission issue occurred.

#23 - Automatic Transmission problem of the 2006 Toyota Sienna
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. This automatic transmission problem happened on Thursday, November 27, 2008.

#29 - Automatic Transmission problem of the 2005 Toyota Sienna
The car involved was a 2005 Toyota Sienna. On my 2005 Sienna xle limited awd, I have noticed at 50+ miles an hour interstate or even downhill) that the car feels like there is excessive rolling resistance, and if I don;t accelerate, very soon it downshifts (have noticed this even on a downhill slope at 45 miles a hour). Service advisor said all Toyota cars as designed to downshift as soon as you take your foot from the pedal (something which sounds very strange to me, since I'm driving other makes and models as well). Seems the transmission is not tuned well. On a separate matter, I noticed several times that the car hesitates to accelerate for a few seconds when I push the accelerator a bit harder at very low speeds, such as when I need to merge into heavy traffic from a side road. It also happened when I needed to change the lanes from a very slow moving lane to one where I needed to accelerate rapidly. Again, something feels wrong about the transmission.
