The contact owns a 2008 Toyota Sienna. The contact stated that while traveling 25 mph, the check engine light illuminated. The steering wheel became very difficult to control and had to be towed. The manufacturer was notified of the failure and diagnosed that the engine needed to be replaced. The VIN was not provided. The failure and current mileage were 80,000.

The rubber portion of the oil supply hose for the wt-1 actuator failed resulting in a sudden loss of several quarts of oil. This oil was carried along the undercarriage and sprayed a fine mist of oil on the windshields of the cars behind the van. Luckily this occurred close to home at a low speed. If this was on the highway it could have caused sudden reduced visibility for the drivers behind the vehicle and could have led to an accident. I am sorry but using a rubber hose on an oil line is one of the dumbest things I have heard of. Fortunately for us, no one was hurt and no damage was done to the vehicle. I don't understand how this has not turned into a recall. This was a big mistake on Toyota's part.

During a recent trip to Alabama from Virginia, our 2008 Toyota Sienna suddenly accelerated while pressing the brake pedal instead of braking. Both times, we were approaching moderately heavy traffic. My wife went to apply the brakes to slow the van. Instead of braking and slowing the vehicle, the van went into full acceleration mode. The transmission downshifted and started applying full throttle. The first time we thought we were going crazy. The second time, both my wife and I watched as her foot applied the brakes and to our amazement, the van started accelerating again! luckily both times, my wife took her foot off the brake pedal and reapplied once the van stopped accelerating and the brakes worked then. I haven't had time to take this into the Toyota dealer yet. We are still under a 30 day warranty with carmax, so I have communication out to them to see how we should handle this situation. I thought this Toyota sudden acceleration story was exaggerated. Now I've experienced it myself.

My wife was parking our 2008 Toyota Sienna with our 3 young boys in the automobile. She slowly brought the vehicle to a complete stop; never using gas, just covering and tapping lightly on the brake. Once the automobile came to a stop my wife pressed the brake a little more in order to put the vehicle in park. At that moment the vehicle accelerated incredible fast, jumped over an 8 inch concrete parking lot divider and crashed into a tree about 10 - 15 feet from the concrete divider. We are certain that this was a "sudden unintended acceleration" incident caused by some mechanical, electrical, programming or other defect in the '08 Sienna. This was not "driver error"! my wife did not confuse the gas pedal and the brake. This was not caused by a floor mat obstructing the gas pedal. This was caused by some type of a design or component defect. How can w be so certain? my wife and I have parked in this parking spot (located in our apartment complex) hundreds of times. To park in this parking spot you first have to make a left hand turn at a stop sign. This stop sign is about 30 - 40 feet from the parking spot, which requires that you make a sharp right turn. Once you press the accelerator slightly to make the left at the stop sign, you do not use the gas again. You simply tap and cover your brake until you make the right into the parking spot. Our vehicle came to a stop. In fact, upon "stopping" one of our 3 boys removed his seat belt immediately before the vehicle accelerated out of control. I'm asking for assistance from someone within Toyota or the NHTSA with knowledge of this flaw. My wife and kids were "fortunate". but this is a "fatal flaw" and something must be done.

While driving my vehicle it began to make a strange knocking sound as I accelerated. I had been driving around town for several hours that morning. I pulled over to inspect the engine, and saw some type of fluid on the left side of the engine and wall. I pulled the oil dipstick out and there was no oil on it at all. Completely dry! I had someone bring me some oil and I drove my car up to the repair shop just a short distance away. They discovered that the oil pressure line -valve cover variable timing-on top of motor to right on passenger side had burst. Part of the line is rubber and that part had ruptured and all the oil had blown out of the engine. My oil light did not come on at any time nor did my check engine light. Even after I stopped it did not come on.

The rubber in the oil cooling line broke down and drained most of the oil from the engine. From looking at the different boards this seems to be a common problem with this hose. Toyota even re-designed the hose with a metal sleeve because of this.

I had a oil hose in my van get a hole. When it happened it spilled oil all over and in my opinion could have started a fire.the hose is connected to a pipe and the hose cannot be replaced. The whole pipe has to be replaced and I replaced mine. My research revealed this is a fairly common problem and that there is a Toyota service bulletin for this problem but in the bulletin they claim it's for seepage of oil. Obviously Toyota knows this is a problem as the new part I ordered is complete pipe with no hoses. The part number for the pipe is 15767. Is this something that can be further looked into as to why this is not a recall that Toyota should properly fix?

Van spontaneously began leaking oil. I brought it into the dealer and was told that it was the vvt1 actuator hose. Apparently this was part of a voluntary recall that Toyota started in 2010 and I was never notified! I called Toyota motor corporation and was told that this was in fact a defective hose but because it was not repaired prior to the 3/31/13 deadline that Toyota would not pay for this defective hose to be replaced. I am certain that I was never notified of this voluntary and worry that many other 2008 Sienna owners are unaware of this defective part and hence will not have this repaired. This hose is under pressure and if it goes completely car will spew oil everywhere and seize up! this is a potential fire and safely hazard!!! Toyota is very aware of this problem! in the end my dealer agreed to cover the cost of replacement, but I am forever dismayed at Toyota's lack of concern for their customers! this was part of campaign recall 90K-2gr-fe V6 engine oil hose.

I was driving down the road and saw smoke rolling out of engine. By the time I pulled over I noticed oil leaking out everywhere. It was the engine oil cooler line and I have since replaced the rubber hose twice and has ruptured two more time since. This is very dangerous. I lost over 12 quarts of oil in the last month.

After driving vehicle for appx. 15 minutes then parking, then coming back to vehicle 5 minutes later I found a pool of oil under the hood of van and called for tow to the dealership. Rob from the Toyota repair service, claims I had bad luck regarding the oil cooler line rupturing. It will cost me $442 to repair/replace and clean the vehicle. After hearing this I checked online and other vehicle owners are having similar problems with similar vehicles that have a V6 engine with towing package from Toyota. The service person claims its not covered under my warranty. He also claims that it wasn't damaged accidentally neither.

While driving home the oil line running from the oil cooler on the radiator exploded. Oil was sent over the entire engine compartment and dripped over the road leaving a trail the block left going to my house. The hot oil spraying over the hot engine was a danger to catching the van and the garage it was parked in on fire. This is an extremely dangerous problem that Toyota is aware of yet has not issued a recall for these vehicles. I was lucky that this happened so close to my home.

While driving my Sienna ac quit & few miles later I saw white smoke come from under the van in my mirror. I tried to slow down & brakes were not working. I tried to pull over & power steering was not working. Without any warning lights. After I pulled over, I walked to the back to see what the white smoke was. I noticed that the bumper cover had motor oil dripping down from the bumper & tail pipe. I noticed the white smoke was actually coming out from the front right side of the van. I ran to shut the engine off but I could not open the driver side doors. Luckily windows were opened due to the ac not working. I took the key out through the window & pulled the hood latch. By the time I got to the hood flames was coming from the right side. I could not open the hood, it was too hot. This happened in matter of seconds. Be aware that all this happened without any warning sound"S or light?S. I called 911. Just in minutes, the van was engulfed in flames & I had no chance to save anything out of the vehicle. The fire trucks arrived about 9 minutes, but by that time there was nothing left of my van. The fireman pointed out to me that there was an oil trail behind the van. The oil trace was visible for few miles. After they finished putting out the fire they showed me where the fire started on the van. It was the area on the left side of the engine around the belt. They said that the fire started from an oil leak on the engine and was started by the burst of oil spraying down on the and catalytic converter. Only two seconds of searching on google, I found out that Toyota is well informed of the hazardous defect. The rubber oil supply line unexpectedly burst open and spray"S the engine oil out in less than few minutes. I never received any recalls or notification about this serious defect from Toyota. Luckily none of my three kids was not in the van when this happened.

While pulling into my driveway I smelled oil and noticed a line of liquid down the driveway. Turns out the oil line ruptured and the engine oil drained almost completely, within a matter of minutes. There was no warning indicator or anything adverse until that moment. Thankfully I live near a mechanic and we were able to leave it there. Apparently this is a known problem at Toyota- as the part was on a national backorder. Thankfully I did not suffer engine damage- many others have, and this should be a recall worthy issue.

The contact owns a 2008 Toyota Sienna. The contact stated that the oil line, which Toyota called the vvt line burst and the all of the oil leaked out of the vehicle. The contact took the vehicle to the dealer who confirmed the vvt line burst and caused the failure. The dealer informed the contact that the part was not under warranty nor was there a related recall. The vehicle was repaired. The VIN was not available. The failure and current mileages was 51,303.

While driving are 2008 Sienna mini van with 51303 miles on it we had developed a sudden loss of oil from the engine. No check engine lights or warning lights came on notifying us that there was a problem. Observed that there was a large amount of oil loss in the driveway. Could track back where we were driving with the oil loss trail in the road. Did some research and learned that the engine in the Sienna is that same as that in several other Toyota (avalons). I learned that there is a vvi oil line is faulty on the engine. Toyota used a rubber hose which results in failure which then results in engine damage due to the oil loss. Toyota recalled the same party on the avalon and is aware that this hose is bad and needs replacement. Toyota issued recall on the avalons but is not issuing a recall on the Sienna. This is the same piece on the two vehicles. They then state that this hose with an average fails at 50-60000miles. They then stated that this hose is not covered under warranty. This hose bursting can cause engine damage and is also a safety issue. There needs to be a recall on this rubber oil hose on all vehicles. They know that this is a bad piece when talking with them. Also if it were to fail they then will state that since this hose caused the engine issues they will not cover it under warranty. This then results in people having to replace the engine in there vehicle for 5-10000dollars. When oil loss occurs it sprays every where getting on brakes, belts, and exhaust which could cause an accident and or fire. Also resulting in serious engine damage. Toyota know this vvi hose is bad and issued a recall on the same hose on the avalons. A five minute search on the internet will show you the issues with motor and vvi hose. A recall must be issued on all Toyota vehicles with this motor which had the vvi oil hose. Thanks

On a rainy Sunday afternoon I was driving 65 mph on the interstate when the check engine, vsc and trac off lights came on. The vehicle was taken directly to the dealer the next morning (69 additional miles were driven). When tested the code indicated to inspect the vvt-1 system, including the actuator bolts and alignment. Upon inspection (requiring the engine to be partially disassembled) it was determined that the vvti gear was coming apart causing debris to spread throughout the camshaft gears and housing only for cam bank 1. this is an obvious material quality defect and Toyota's only statement is "we don't have a recall for this". my van is 90 days past the 5 year & 17,369 miles over the 60,000 warranty. (note: Other manufacturer's offer a 100,000 powertrain warranty). This van has only been serviced by this dealer. This single repair bill is $4,295 with no guarantee the other cam bank won't do the same thing, requiring another high service bill. After 3 days of waiting for Toyota to investigate, they only offered a goodwill contribution to the repairs of $2,400... but only after I submit paid receipts and then wait 10 weeks for them to reimburse me. They flat out refused to send the payment to the dealer. This is Toyota's premier family vehicle and if the engine has seized while driving could have killed my family or someone else. I have driven Toyota's for over 15 years and never heard of this kind of materials defect and then to be treated this poorly over a major safety issue that is a direct result of poor quality materials. I guess they would have been more interested if someone had died. I think everyone who owns a 2008 Sienna should be aware that this model has a vvti gear material quality defect that can be expensive to repair or cause the engine to seize while driving and kill someone. Who knows if other 08 models are also affected.

There was a pin hole puncture in the flexible material the oil cooler is made of. The result of this is that all the oil is forced out of the engine very quickly under high pressure. There was no warning until I heard engine noise. I had the van towed in and had the part replaced. The current factory authorized part is now made out of metal. The dealership then informed me that because of the failure of the part I would need a new engine.it will cost $10,000. I asked if there was anything I could have done differently to prevent this I was told no. My engine is still under warranty but the part that caused it is not. I realize parts break but this part is not a maintenance part and the expected outcome of its failure is engine replacement. This I have found from experienced auto people is common knowledge. I believe this is a defect that Toyota knows about and is willing to ignore by invoking their warranty as a reason to allow this to happen to unsuspecting owners. Oh, when I contacted Toyota for help with my $10,000 problem, they offered me dinner. At this point I own a $30,000 piece of junk ( I owe $20,000) none of this would have occurred if the part had been made out of metal originally or if there was some kind of safeguard built in to warn you of the potential problem. Unfortunately that is not the case. Please help.

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.
