As a result of the transmission cooler being a part of the radiator system, the transmission cooler ruptured while driving causing immediate loss of power and the engine to overheat. This malfunction also caused coolant and transmission oil to contaminate the engine compartment as well as the transmission. This is a major iengineering flaw and safety issue as I was on the interstate when it happened and was stranded on the side of the highway until help could be obtained.

The contact stated while driving 40 MPH going up a curvy road, the ABS service warning light illuminated, and the vehicle lost motive power for several seconds before independently regaining motive power. The contact stated that the failure was intermittent. The contact took the vehicle to a local dealer to be diagnosed however, the mechanic was unable to retrieve a fault code. The manufacturer was not made aware of the failure. The failure mileage was approximately 160,000.
The rubber part of the VVT-I oil line appears to worn and leaking. There is a Toyota Campaign to replace this faulty designed oil line with a full metal line, but for some reason my 2007 Toyota Sienna VIN is not showing up with this campaign. The oil will leak from the engine and cause failure. Please re-check which vehicles are impacted by this Toyota design problem in this VVT-I oil line.
The contact owns a 2007 Toyota Sienna. The contact stated while stopped at traffic light, the vehicle stalled with the brake pedal depressed. Several warning lights illuminated on the instrument panel. The contact shifted the vehicle into neutral and coasted into a driveway. Upon inspection, the contact discovered that there was no oil in the engine. The contact refilled the oil however, the oil immediately leaked out the vehicle. A mechanic arrived on scene and replaced an oil hose. After the hose was replaced, the contact heard an abnormal knocking noise in the engine. The contact took the vehicle to several independent mechanics and was informed that the engine failed and needed to be replaced. The contact had the vehicle towed to Suburban Toyota of farmington hills (25000 haggerty rd, farmington hills, mi 48335) who confirmed there was an engine failure. The contact then had the vehicle towed to an independent mechanic where the engine was replaced. After the engine replacement, the contact experienced several transmission issues. The contact stated that while at a stop, the vehicle independently shifted in and out of gear without warning. Also, while in reverse, the vehicle coasted and jerked upon slight depression of the accelerator pedal. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 126,300.
Driving 55mph on frwy, van started smoking in the rear and oil on back of van. Slowly drove short distance home and lights on dash came on upon arriving home. Oil leaked on street where we parked. Had mobile mechanic look at it. Oil cooler hose had burst. He replaced it, we drove the van 50 miles on short trips.when on frwy, it happened again about 3 wks later. Had towed home. Same hose busted again. Looked on internet sites & found same problem has occurred to many people with same van year. Longterm ongoing problem. Called tejas Toyota in humble, tx and svc mgr said Toyota offered an extended warranty (knew there was a problem), but it ended at 100,000 miles/10yrs (we have 120, 900) and is 2007 van. We've already had it towed and fixed twice. We're recovering from near death/covid afraid to drive it since we can't trust it. Based on internet stories by others with same problem, & svc mgr at Toyota opinion, fear is warranted. Our van was repaired 2X w/ same type of inferior hose put on van when built by a mechanic not at Toyota. None of us realized inferior part was the problem.now we need to repair it again with a "kit" that Toyota specifically made because this is known problem after we spent many 100S of $S repairing it using same type part when built. Wouldn't fix it when I called in 2015. It had to break 1st per Toyota when I checked on it in 2015 when got notice.Toyota should repair it at no cost & reimburse me for the expenses I've already had. My husband had covid and almost died and it happened the day after he was released from a month long covid hospital stay and again when I was taking him to therapy for covid 3 wks later. We could have had a accident, been injured, when the van stops with no notice or warning lights.Toyota Corp. Takes no responsibility.it's our problem, not theirs. Can't drive van. Will happen again w/out warning. Help please!!!

When accelerating the engine makes a tracking noise like bad vavle springs or camps. Only hear the noise when accelerating. Started happening after 60K miles. Common problem with the engine Toyota uses with the Sienna.
As I was driving the van, I noticed a smell like burning rubber, although all gauges were normal and no check engine light was on. Since I was close to home, I pulled into the garage and noticed smoke coming from under the hood and a trail of oil on the drive way. Within a few minutes, there was a large puddle of oil under the vehicle as well. I had it towed to the mechanic and was told the oil cooler hose had broken. The mechanic said if I had driven it to the shop, I likely would have ruined the engine because the oil loss was so significant (out of 5 quarts, only.25 was remaining). The mechanic also said that Toyota was aware of this issue but did not issue a recall, even though the replacement hoses are now steel and not rubber. This is a safety issue as the engine could have seized up while running (due to the quick loss of oil) causing potentially serious accident and injury.
Oil cooling hose broke and all engine oil leaked from engine. Vehicle was in motion but made to parking spot. No warning of event and no dash/engine light signaling problem. Only oil on ground under van signaled problem. Van was subjected to recall in 2011 which replaced hose. Dealer replaced parts as repair with a complete redesigned part removing rubber hosed all together. This was not a recall but owners expense. Manufacturer never notified owner of this defective part or event possibility.
Oil line ruptured due to rubber failure. This oil line was replaced in 2012 with same line as originally installed. Failure can be catastrophic for engine as oil is discharged quickly and with no warning or indication. Vehicle was in motion on a highway when odor and noise made me stop and check. Had to be towed and repaired. Cost over $500.
I was driving back from this weekend on a highway and I noticed a thumping noise coming from the front of the vehicle and then I noticed an engine light came on and instinctively I knew that was a bad sign for all six of us my family and friends. So I immediately exited the nearest exit ramp and that's when the engine stalled and I couldn't move any longer. We called our insurance company for towing and the cops to steer clear of oncoming traffic since we're on the second lane on the exit ramp. I thank god that nothing happened to us but it shouldn't happen to my vehicle with only 93,000 miles with regular maintenance and a clean driving record.
Oil cooler pressure hose explode while driving with my kids back from the church oil were leaking all over the street the car was smoking in front drivers were honking and scream your car is on fire and a nasty smoke where coming out of it. If I was not alerted by a good samaritan my kids and I will pay our lives. I called main office Toyota and made a complain but they refused to help although this part 'hose is not used by Toyota company for lack of safety. The supervisor was not listening and does not care about his consumers lives instead he said oh luckily some body told the car is smoking and we will do something about if it caught on fire or there is life lost. This respond is totally unacceptable he also refuse to email me a letter saying this part of the car was not recalled although it did.

Oil cooling hose ruptured while driving the car at approx. 60 mph on the highway. Black smoke began to pour out the back of the car. Oil sprayed over the engine and underside of the car and rendered the car undrivable. Damage also sustained to the drive belt tensioner system.
I was told today that my cooler hose ruptured and I had to take it immediately to a auto repair shop. I was driving to work and the car started making a clicking noise and felt weird to drive. I got to work and was told to check the dip stick. Was told it sounded like I had no oil. I was thinking, that wouldn't be right I just got an oil change about a week earlier. It was bare. Completely empty. I then proceeded to get it to a repair shop as it was an emergency. The auto place told me that it needed a kit that they would have to buy to replace the cooler hose and would take awhile to fix this. It would be the only way to fix this. And they cant guarantee me the engine didnt get effected by this situation. I did my research on this issue and it is extremely dangerous and expensive. I am now out $500 and half a day at work. I was driving to work at 7:15am on highway 44 going about 45-55 miles an hour. It was terrifying and once I got to my work and realized that my van could have stopped on me in the middle of traffic whenever it wanted to this morning or the engine could have blown up and cause a real accident. This is a serious danger to me and people around me. I had no clue I was in danger, I had no idea that my van was messed up. There were no signs, no problems, no anything. It just out of nowhere drained the oil. I drive 35-45 miles to work. I wish I would have known about a "recall" on this. I wouldn't have had it checked way before.
Toyota Sienna 07 to 13 has oil cooler hose leakage problem, cause it made of rubber and aluminum, rubber part of this cause leakage, because engine oil goes from it with pressure and after some time rubber part goes bad and start leaking when you start the van it comes out, it happens with me twice, first my 07 Sienna has happens I buy a used pipe from junk yard and fix it, after fifteen twenty days it happens again, all of a sudden on a free way my van heat up in left lane and stop engine, I almost got killed for this sudden stop, van has no oil left in engine and it heats up, I pull my van asside and find out that engine oil cooler pipe is off the hook and I am out of engine oil, how I come back its a different story, but when I call Toyota dealer ship for recall they told me this is not a safety reason so L have to fix it myself, my question is that for there cheap material pipes I can got killed, my engine can go bad, but this is not a safety issue for them, can some one help me.
Driving car in town for about 10 minutes. Stopped at friends house and noticed when I backed out a large oil puddle. Got out and looked under car to see undercarriage covered in oil from front of car to midway down car. Could not tell where it was coming from so I called tow truck to take to Toyota dealership. They found small hole in oil cooler line was spraying oil out. It was half empty of all its oil in that short amount of time. The dealership told me it was going to cost me $360 to replace oil cooler lines. I was very lucky I had not driven very far or probably would have been catastrophic engine failure. After quick check on internet, this appears to be a common issue with oil supply lines in this and other model years. Also looks like there is a new all metal oil supply line and a warranty extension (ZE2), neither of which I was made aware of by my dealership and was very difficult for me to find.
Oil cooler piper ruptured after starting and driving the vehicle causing rapid oil loss while being driven to work. If I did not notice the puddle of oil left by my wifes car she would have driven it home and surely blown the engine. The part was replaced in 2010 during limited service recall but still burst 5 years later.
The oil pump assembly failed. It was partially made with a rubber hose that did not perform as it should. It needed to be replaced with a solid metal part. Although there was a safety/service bulletin listed by Toyota on this part it cost almost $1200 to repair.
