| I have had this van since new. air conditioning stopped working after 4 years with less than 60000 miles. first transmission problem started at 68000 miles. the transmission problem first reared its ugly head when i was backing out of a parking spot one early morning in november 2011. it sounded as though i had run over something. after getting out of the van and looking around it appeared as though everything looked good. i got back in the van and started to drive and could hear a rubbing sound coming from the front of the van and noticed it would slow down quicker when taking my foot off of the accelerator, so much so that your body would lean forward. also, i noticed the van would now slow down instead of picking up speed when coasting down a hill which is something it had never done before. i brought the van into my local toyota dealership that week to have it looked at but they said that was the way it was supposed to run. i told them 68 000 miles of driving experience since it was new has told me otherwise. they persisted with their everything was as it should be story and that it could be the brakes sticking occasionally. i even told them that the rubbing sound goes away when shifted into neutral which would eliminate the brakes as the cause. the vans transmission finally failed in february of 2013 at 82 000 miles after i had brought the issue up 4 times with my toyota dealership while getting other service completed, and yes they did change the transmission fluid before all of this happened. the transmission diagnosis and subsequent repair/rebuild quoted by the toyota dealership was $4000. mr. transmission charged me $3100. like me, you have either already purchased a toyota product or are considering the purchase. all i can say is google transmission and problems and you'll find lots to read. good luck. | |||

| After a short trip, 5 miles, i was backing into my driveway when i noticed some fluids on the cement. i checked the liquid and was not sure if it was coolant or transmission fluids so i called my mechanic and he recommended that i should have it towed in .it turns out that the problem was that a connector at the bottom of the radiator cracked and was mixing the coolant with the transmission fluid ,it appears that a defective fitting was the problem. it cost me $977.3 to replace the radiator and flush the transmission. my mechanic said if i would have continued driving with these 2 fluids mixing i would have damaged the transmission beyond repair for a bill of $3,000. more if this is a common problem on these cars people should at least be notified what to watch for or better yet repaired by the company. *tr | |||

| On mon 10/22/2012 at 11:15 am i experienced sudden uncontrolled acceleration driving my van. i was traveling on i-696e in detroit at a constant 70mph, then slowed to 45mph due to construction. as traffic cleared the construction, i pushed the accelerator pedal to pass a semi-truck. i felt the accelerator continue to depress, i completely pulled my foot off but the pedal did not come back nor did the vehicle slow down. rather, it did just the opposite and continued to accelerate. i attempted to brake hard with no response--the vehicle did not slow down. then i put the van in neutral to slow down the engine with no results, the van continued increasing 60+mph with no foot on accelerator. this is when i became extremely frightened. the vehicle was pulling from side to side. i looked down to see if there was any interference from the floor mat and none was seen. i tapped gas pedal - no response. next i put van back in drive and braked --no response again. then i downshifted to 4th, the engine did not slow, and further downshifted to 3rd gear. finally, the engine responded and slowed. i used the gas pedal cautiously as i then shifted to 4th so that i could exit the freeway. i parked at my office & immediately called my husband first and explained what happened and i then immediately called the our toyota suburban dealer. they told me to bring it in for inspection. i was still shaking when i brought the vehicle in and extremely upset. after two inspections, they stated sudden acceleration was caused by the floor mat. although this seems reasonable, it does not explain why brakes failed to overcome the engine, and shifting to neutral failed to disengage the transmission. the vehicle scares me to death. i do not know what to do next. i consider myself a serious witness as a registered nurse (rn/bsn) with 20 yr manual driving. ref toyota case #[xxx] and #[xxx]. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr | |||

| Engine/powertrain hesitates for 1-3 seconds when accelerating slowly, or accelerating quickly after slowing down such as when slowing down in an intersection, making a turn, or in slow traffic. engine has piston slap for 3-5 minutes after a cold start in weather below 40 f. the slap becomes louder with colder temps. shifting into gear with a cold engine can cause the vehicle to lurch due to high idle. driver must have foot firmly on brake before shifting into gear. problem diminishes if engine is allowed to warm for 45-60 seconds. when parking, the driver must keep the brake fully depressed, shift into park, pause 1-2 seconds before releasing brake. it seems there is a brief delay between gear lever being placed into park, and powertrain actually going into neural/park position. releasing the brake too soon will allow vehicle to roll ahead 3-6 inches. | |||

| 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. | |||

| 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!! *tr | |||

| 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 be 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 siennas is sound. updated 03/10/10 *bf *tr | |||

| 2007 toyota sienna: transmission temporarily fails to engage the correct gear after decelerating then re-accelerating resulting in a pause or hesitation before control is again regained. this occurs most frequently when slowing for turns at intersections or behind slowing traffic or attempting a lane change. three service calls have been made on the vehicle which were recorded as a bad ecu program. service technicians reprogrammed the ecu to reset adaptive memory and shift points however there was no change in performance. it was suggested that this was a design problem which had been corrected in later model years. the potential consequences of the transmission's failure to immediately engage in the correct gear are the loss in ability to quickly accelerate out of a pending collision or to avoid slowing in the middle of an intersection and causing others to have collisions. *tr | |||

| 2007 sienna, hesitates after re-accelerating between 5 to 10 mph. acceleration pressed but car does not move for 1 or 2 second. took to dealer 3 time and also talked to toyota hq (dealer did find problem but hq said not to put anything in report saying there is a problem) they just saying nothing can be done to car right now a.k.a no updates available also automatic transmission has lot of jerks when it switches gears... example: half stop at stop sign and it accelerates without depressing the pedal and rpm going up but car not moving until half way down to intersection. *tr | |||

| Transmission slipping on 2007 toyota sienna van. when traveling at 6-8 mph the transmission will slip when the accelerator is depressed. the van will hesitate then suddenly lurch forward. the dealer says that this is normal and will not do anything to repair it. *tr | |||

| Engine/transmission hesitation/non-responsiveness. this is particularly apparent when you lift off the throttle to go over a bump or turn. when you press the throttle after that, the throttle does not respond quickly like any of my other vehicles. this happens all the time. *tr | |||
