 We have owned the sienna for 4 years and 53,000 miles without incidence. we have had it serviced by the toyota dealer and have had all scheduled maintenance. one afternoon, after driving the sienna all day, we pulled it into our driveway (which is on a slight incline) and placed it into park. after doing this, instead of the brakes being applied, the sienna rolled back as though it were in neutral. we brought the sienna to the toyota dealer who inspected it. they told us the pin that enables the brakes upon placing the sienna in park was completely shot and the entire transmission would need to be replaced. the service manager said he has never seen something like this before and that these pins don't wear out over time. the service manager also told us that you would only see damage to the pin if you were driving the car and then suddenly put it into park while moving at a high speed. the service manager contacted the offices of toyota corporate and had the case reviewed. it was determined by toyota corporate to be related to the warranty and they are replacing the entire transmission. *tr

 The car was driven normally in gear d at 35 mph but slipped out of gear for no reason. i stopped, put in park, turn off the engine, waited a few minutes and restarted the car. it would then only work in gear 3 but i had to floor the gas pedal. after stopping multiple times, i was able to reach home. my 2008 sienna can now be driven forward in reverse gear.

 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.

 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 accross 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 furter investigation and a possible recall/fix. this happens almost ever time i drive this vehicle.

 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.

 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.

 I am concerned about the electronic control system in my 2008 toyota sienna van. rather than the acceleration problems associated with the recalls, my van sometimes does not respond appropriately, eg. there is excessive hesitation and lack of acceleration when the gas pedal is depressed. there are other times, esp. going downhill, when the car seems stuck in an unusually low gear (automatic transmission). when i've reported my concerns to the dealer (each time it's been serviced for 2 years!), the service rep says, yes, my avalon does the same thing. it's because the gas pedal is no longer mechanically attached; instead it relies on radio waves which can be affected by temperature and humidity. so, while this does not appear to be as dangerous a problem as the unintended accelerations, i can imagine a scenario when i would need to accelerate, the car would not respond, and i could be rear-ended. i felt it was important to report this apparent problem, as the testimony i saw from toyota officials seemed to heavily discount the possibility of there being problems with the electronic control systems. but something isn't right! i previously drove a 2000 sienna and did not have any of the hesitation i have described above. (unfortunately, that engine died at 78k, i believe, due to the white smoke problem that had been subject of an earlier recall!) note: stated date is most recent date van hesitated and was stuck in a low gear. problem first noted in nov. 2007 with less than 1000 miles. *tr

 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. *tr

 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. *tr

 2008 toyota sienna 3.5 v6 has had piston slap since new. toyota knows that there is a flaw in all of these engines but because there have been no failures and few complaints , they are choosing to do nothing about it. i like engines and i know that where there is noise there is excessive wear and potential future failure. *tr
