general problems of the 2007 Toyota Sienna

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 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 driving 40 mph going up a curvy road, the abs service warning light illuminated and the vehicle loss 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.

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.

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 front lower oil cooler pressure hose (Toyota part no. 15767 31010) started spraying oil out while the van was being driven under normal operating conditions in a residential neighborhood with young children in the car. Had this occurred at a higher speed (on a highway), all the oil would have sprayed out and the engine would have seized. This could have caused an accident or the van could have caught on fire. This is a well known problem with this part that Toyota has done almost nothing to fix or prevent. We were extremely fortunate to have discovered this problem immediately.

I had a catastrophic loss of oil from the underneath of the car, there was a recall on this problem which was fixed back in 2011 but almost every one online that has had this fix has to get it done again. Toyota are not seeking the fix the problem again with a metal hose and we are having to pay for the replacement. Https://www. Google. Com/search?q=t-sb-0201-11&oq=t-sb-0201-11&aqs=chrome. .

Tl-the contact owns a 2007 Toyota Sienna. The contact stated while driving approximately 20 mph fire was coming from underneath the hood of the vehicle with out warning. There were no injuries. The failure was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was 99,000. Ss.

My wife was driving our 2007 Toyota Sienna on a major road when she noticed smoke coming from under it. She pulled into a parking lot and shut the engine off, avoiding engine seizure because within just a couple of minutes it had lost 2 qts of oil onto the ground due to a rupture in a rubber oil vvt-1 line. After reading online I found out this is a very common problem which Toyota has refused to address properly. In 2009 Siennas the line have been switched to all metal leaving the rest of their earlier customers with ticking time bombs. This type of failure is unacceptable, an engine seizure at 70mph will be deadly and the spilt oil on the road posses hazards as well. A Toyota dealership wants to charge over $500. 00 to replace this $23. 00 hose.

I am the second owner of the vehicle. I was driving on interstate 5 at 65 miles per hours from sacramento to los angeles. The time was 1600 on 13 April 2014. I did not notice any crack or noise from road debris damage while I am diving. The red low oil warning light on the dashboard did not turn on at the time when the incident happened. I was pulled over a rest stop to use restroom; I also walk around the vehicle to conduct a visual check and fluid check at the same time. I was discovered engine oil was all over the engine bay, undercarriage and the back lift door during the visual check. When I checked the engine oil, the dip stick showed no engine oil. Again, the red low oil warning light did not turn on which indicate low engine oil at that time even the engine had no engine oil. Vehicle was towed to Toyota dealership and discovered an oil cooler hose which make out of rubber was ruptured. Even the oil cooler hose was replaced with a metal oil hose; the engine was damaged by operated without engine oil for a significant period. Prior to the trip, I purchased the all metal vvt-I hose from a local dealership, again no warning from the dealership. I used a local repair shop to replace the vvt-I hose locate at the passage side of the engine to an all metal pipe since I have knowledge on the rubber vvt-I hose have the same rupture issue. However, I have no knowledge on the t-sb-0201-11 which is the Toyota technical service bulletin title oil cooler pipe seep. There is recall regarding shift lock solenoid and severe corrosion of the spare tire carrier cable on the 2007 Sienna, however, there is no recall on possible rupture on vvt-I hose or oil cooler hose. If the recall was issued or at least warned by dealership, I will fix the oil cooler hose at the dealer or a local repair shop and avoid the engine damage which leaded to engine replacement.

The contact owns a 2007 Toyota Sienna. While approaching a stop, the contact noticed steam rising from underneath the hood of the vehicle. The contact looked under the hood and noticed that the engine was covered in oil and there was a puddle of oil on the ground. The dealer replaced the oil feed line, but the failure recurred. The manufacturer was not notified. The approximate failure mileage was 109,464.

Driving my kids to school, which is 3 miles away, and I suddenly smell smoke. When I was coming back, I suddenly here a noise. All of a sudden, the vehicle stops. I had to hire a wrecker to bring it to my house. Once the vehicle was at my house, I tried to find what the cause of the noise was and when looking under the vehicle, I notice the oil had come out from somewhere. I opened the hood of the vehicle to check for the oil and it was empty. About a month ago, the dealer made the oil service. I wonder what happened.

The contact owns a 2007 Toyota Sienna. The contact stated that the vehicle failed to accelerate. The contact noticed there was a trail of oil behind the vehicle. The vehicle was taken to a private mechanic, who stated that there was a crack in the oil sensor tube. The vehicle was not repaired. The failure was reported to the manufacturer. The VIN was not available. The failure and current mileage was 110,000.

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.

The contact stated that the damage was due to mice entering the vehicle and chewing the wires. The vehicle was repaired. The approximate failure mileage was 16,000. Updated 03/05/lj.

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.
