| 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 | |||

| Driving on the freeway @ 85mph when the check engine light came on. promptly, i pulled the toyota manual which said could be faulty gas cap and may go off with consecutive drives once fixed or if it stays on after to go to dealer. the car was running fine so i headed to my exit to pull over. shortly, thereafter a horrible diesel engine grinding noise. i had just had my tires rotated (replaced just one month prior) that weekend and the oil changed the weekend before. as i was about to pull over the engine oil light flashed. when i pulled over i immediately checked the oil stick dry we had been given the run around about the part by mossy nissan that the part was on backorder and was part of the recall. the vehicle was later towed to toyota of poway and for $500+ to inspect and replace this hose(not part of recall) wanted another $3000 to tear down the engine and the addl charges to fix i have religiously had my oil changed and have always had my toyota certified mechanic work on my car. i contacted toyota consumer service for assistance in fixing the problems they indicated they would not help since the hoses were not part of the recall. the hoses are 2 rubber hoses that have clamps leading to a triangular metal piece. the hole was not in a location that something could have pierced according to my independent mechanic who tried to get the part from the first dealer....which leads to the fact that these are faulty hoses that deteriorated. toyota has offered a goodwill payment of $750 towards a new or used certified toyota car. but that is at a 20% interest rate. it is my hope that others will see this and get this fixed before they end up like me single mom of 4 without a car working 5 days a week 150 miles from my babies and can't even go home to see them till the weekend. a big thank you toyota. i have paid $800 out of pocket. *tr | |||

| Failure of a defective rubber oil cooler hose occurred at app. 5:30 pm on 2/11/2013 while the sienna was being driven on a city street. the vehicle rapidly lost most of its oil, and incurred significant and very costly engine damage (resulting in the need for replacement of the engine short-block, plus other collateral engine repairs that the toyota dealership and toyota engineering eventually determined necessary). see toyota technical service bulletin t-sb-0201, dated 12/21/2011. the oil seepage term used by toyota in this tsb is a complete misnomer, as the oil loss was rapid and resulted in oil spraying profusely under the front of the vehicle. toyota had not previously communicated any information to its unsuspecting customer regarding this specific defective part. on 3/3/2011, the customer discovered through his own personal research the scope and magnitude of toyota's pervasive failure history with a very similar defective rubber oil supply hose. the defective rubber oil supply hose is the subject of a current multi-part limited service campaign (lsc) prior launched by toyota, however toyota is incredibly claiming to the customer that this lsc campaign (which is set to expire on 3/31/2013) does not cover the defective oil cooler hose. in the customer's opinion, toyota has demonstrated gross negligence in not including coverage of both defective rubber oil hose parts under the current lsc (or, not launching a separate lsc addressing the defective oil cooler hose). this defective rubber oil cooler hose could be described as a ticking time bomb for owners of affected toyota highlanders (2008 - 2011), highlander hvs (2011), siennas (2007 - 2011), and venzas (2009 - 2011). the customer is continuing interface with toyota, for toyota to accept full financial responsibility for all customer costs incurred in this matter. | |||

| 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. | |||

| On march 12. 2010 i was traveling to arches national park with four other passengers. on the way, we decided to stop by bryce canyon utah. i was driving a 2007 toyota sienna through 26 s. main street bryce canyon city. because of bad weather condition. i had put the car in gear 3 and was driving 5 miles per hour. suddenly i heard the engine accelerate and felt the car push forward. i let off the accelerator and cautiously pressed the brakes as hard as i could, but brakes did not respond and the car continued forward about 150 feet. somehow i managed to turn right on center street and bumped onto the curb to be able to stop the car. after the car came to full stop, the engine sounded normal. because of this incident, we changed our schedule and returned home. *cn | |||

| 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 | |||

| I bought a second hand 2007 toyota sienna le in june 2009. the vehicle had about 49,000 km. i noticed that vehicle had produced unusual noise when started at cold. it sounded like diesel engine. i took a vehicle in to a toyota dealer and they attempted to correct the problem. apparently, there is a tsb issued on this problem. although i appreciate the dealer's honest effort in correcting the problem, the noise is still there when engine is started at cold. *tr | |||

| I have a 2007 toyota sienna. when the engine is cold and started i get a noise that sounds like a lifter problem. although the weather will effect the intensity and duration of this noise it is always there. the toyota dealership i took it to had a factory engineer come out and he heard the noise and said it was normal and attributed it to piston-slap. at this time they are telling me there is no repair for this condition. they acknowledge there is a noise but they say they can do nothing about it. this noise developed approximately around 20,000 miles on the vehicle. other sienna's that acquaintances own do not have this problem. some mornings when it is cold out the noise is so loud it turns heads as i drive down the street. evidently this is a problem that toyota knows about but refuses to fix. *tr | |||

| Catalytic converter emits strong sulfur odor into passenger compartment. the smell made my family sick with headaches. toyota reps told me to note what gas station i go to and it may take multiple visits to fix since no one else reported similar problems. *tr | |||
