Engine Oil Leaking Problems of Toyota Sienna

While driving I heard a noise coming from the engine. I stopped and park the vehicle, opened the hood an noticed oil all over the bottom part of the engine. (oil leak or seep from the engine oil cooler pipe). I purchased this vehicle from a Toyota dealership in stanford CT. And I was never advised of this issue, nor from Toyota or the dealership itself, even though a communication was sent to all Toyota dealer principals, service managers, parts managers. I spent $60. 00 dollars for tow truck / $148. 14 on Toyota original parts / $270. 00 for labor. I spoke to two company Toyota representative and was informed that they no longer are responsible for covering this problem as warranty coverage expired on March of 2020. I was expecting for Toyota to cover my expenses as this is a factory engineering design done wrong. Roberto martinez 374 wadsworth Ave apt 6c new york, NY 10040.

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!!!.

All the oil leaked out due to a faulty oil cooler pipe. The part is faulty plastic and Toyota knows this is a defective part. They did an "enhanced warranty" instead of a recall. This happened in my garage when the vehicle was stationary. Messy and dangerous.

Lower oil cooler line developed hole and leaked engine oil while in motion on county highway.

Toyota has a known failure issue with the engine oil cooler hose on this model. With this issue, a defect in the hose causes oil to leak rapidly from the hose. A search of the internet can find many instances of this issue, with catastrophic engine failure resulting in certain cases. Toyota has issued warranty enhancement ze2 to cover this. The warranty term for this item is extended to ten years and 150,000 miles. I experienced this failure last week. It occurred as I was pulling into a car wash. Smoke started coming from my engine and the car wash worker noticed oil leaking from underneath. I had to have the vehicle towed and the hose replaced. The total cost was $665. I attempted to get coverage from Toyota, but my request was denied due to the fact that the mileage was at 167,000. The reason for my complaint is that a major, known defect such as this should not be time or mileage limited. Given the catastrophic failure that can result from this defect, Toyota should have been replacing the defective hoses rather than forcing customers to endure the problems of failure in the field, which often resulted in blown engines and the need to have vehicles towed in for repairs. If Toyota is not going to take the step of preventing the problem, they should at least take care of the problem when it occurs - regardless of age or mileage - because the cause is clearly the result of a known defect. I contacted Toyota warranty service for reimbursement and my claim was denied. I called back and asked to escalate it. I was transferred to a higher level agent who again denied my claim and told me to address my complaint outside of Toyota, which is why I am filing here. With this complaint, I am seeking reimbursement of my $665 costs. I further suggest that Toyota be urged to revise warranty enhancement ze2 to remove the mileage and time limits.

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.

2007 Toyota Sienna oil cooler line line has a pinhole leak never indicates that there is no oil or low oil pressure.

I had a catastrophic oil leak all over my driveway and garage. Reseached history of this type and found it was it was a rubber hose associated with oil transfer (also called the v v t 1 actuator hose. A voluntary recall on this part ended in 2013. I will have it fixed by a local car repair shop but if this is a known part failure for years, why would Toyota not make a mandatory recall of this faulty part? my 2009 Toyota Sienna which I just purchased 2 months ago will now have a major car repair.

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.

Variable valve timing oil supply line sprang a leak at bend on rubber tubing. Toyota has a new replacement tube ,but not paying for tube or labor.

My wife was driving the minivan with both kids in the car after grocery shopping and picking them up from the preschool. While she was driving into the garage she smelled and saw oil fume coming out of the hood. She thought the car was going to catch fire and grabbed the kids and got out of the van as quickly as she can. I got her call and rushed home from work. It turned out there was a sudden failure of a oil cooling pipe on the engine. All of the engine oil had almost leaked out (there was maybe about quarter of inch showing on the dip stick). After we towed the car to the dealer, we found out the oil had leaked from an engine cooler pipe which was poorly designed and over time it could develop a slow seep leak or in our case failed in a sudden burst and caused the oil to leak out like a running faucet. We were extremely fortunate because it occurred just while she was driving the van in our subdivision. Toyota had an extended warranty for this issue last summer but didn't have a recall for this. If it happened while we were driving on highway and we didn't pay attention to the engine light, the engine may burn or worse it could seize and cause accident. After a little research on the web, I found out there are a lot of people had this same issue. Toyota actually had a recall other models of cars for the same issue several years ago. I wonder why they didn't recall the 2008 Sienna and they should have. I want to report this and hopefully force Toyota to start recall on this issue for all impacted models so others won't have to experience this and avoid potential accidents. Thanks.

Toyato known defective timing chain gasket. Leaking oil.

While traveling at 75mph on interstate, I noticed heavy white smoke trailing vehicle. Slowed and pulled over. Inspected engine and found large oil leak. No check engine or low oil lights illuminated prior to smoke. Entire bottom of the car coated with oil, including exhaust system, front passenger tire and rear tires. No oil registered on dipstick. Towed to Toyota dealer where the car was purchased. Failed part was the oil cooler hose. Technician showed me the faulty rubber hose which had a pin-hole leak and there was barely one half quart in the engine, which holds 6. 4 quarts. Judging by how often I had been looking in the rear view mirror due to traffic, I'd estimate the leak was only a few minutes in length and the engine would have been without oil and at highway speed very soon if I hadn't noticed. This is not an extraordinary event until you realize that the oil hose that failed was part of Toyota's 90k oil cooler hose limited service campaign for 2gr-fe v6 engines in 2011. I had my car undergo this fix, which simply replaced a rubber hose with another rubber hose which was supposedly made from a compound that better resists hot oil. The replacement hoses are failing, which is what Toyota TSB-0201-11 "oil cooler seep" (Dec 21, 2011) is meant to cover and it replaces the rubber oil hoses with an all-steel hose. However, it only applies to customers still under the 36,000 mile warranty and with a "seeping" hose. Most 2007 Sienna owners, like me, were well past warranty mileage in 2011, had no indication from Toyota that the rubber oil hoses were potential problems and are only getting the steel hose after catastrophic engine oil loss. I was billed $532 for the oil cooler hose replacement and quoted $307 to replace the O2 sensor which was damaged by the volume of hot oil that sprayed on it. Huge oil loss at highway speeds. Toyota knows, but many owners do not.

First, I noticed some oil stains on my drive way, then I drove my minivan to a local Toyota car dealer for check up and routine oil change. Next day, I noticed a bigger oil stain. Anyway, I had an appoinment and have to drive my minivan to my dentist office, on the highway, I saw smoke came out of my front hood. Then, I drove it to the same Toyota dealer afterwards. It was quite scary driving and seeing smoke came out of my front hood especially with my young daughter on board today. At one moment, I thought my car will be on fire. On the paper, I was told that my leaking is from rack and pinion steering system. I called Toyota customer service, and the person who assisted me state his surprise of this rack and pinion leaking for such a low mileage car. I would like to file a mechanical damage report toward Toyota defective parts.

The contact owns a 2007 Toyota Sienna. The contact stated that upon inspection, it was found that there was an oil leak. The contact diagnosed that the oil cooler hoses needed to be replaced. The manufacturer was not notified of the failure. The vehicle was repaired by the contact. The approximate failure and current mileage was 79,303.

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.

The contact owns a 2007 Toyota Sienna. The contact stated that while having the oil changed, the mechanic stated that the vvti oil pressure line was leaking. The vehicle was taken to the dealer for diagnosis where it was stated that the oil pressure line needed to be replaced. The vehicle was not repaired and the manufacturer was notified. The approximate failure mileage was 70,000.

The oil cooling line suddenly ruputured with no previous warnings or leaks.

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 alot of smoke coming out from engine, pulled over and turn off and all came out of car and oil started leaking. Next day took van to the Toyota dealer and they checked eveything was fine but there was a part( oil hose no. 1 ) that was been recall and it been fix by Toyota dealer but same hose was blow which is dangerouse that Toyota dealer told us and he was surprised that could not happen after replace part that mean they still have that same problem and we was on I-10 , we stop the van on time otherwise we wont able to move van and we might lost our life so please investigate and save others life .

1. Engine lights came on alerting us to a problem (check engine, service engine, etc. ). After alleged repair, spouse drove to families house approximate 600 miles away and found a significant amount of oil had leaked from the system - oil had been changed as part of the fix. A second dealer, at the new location, "fixed" with the same hose again, with similar results, though my spouse only drop 120 miles. She is unable to continue the trip home due to this issue. 2. After taking to dealer, was told the vvt oil line was a known faulty part and needed replacement. Was not a "formal" recall, but was considered an internal recall to Toyota that needed to be fixed for "free". Both dealerships claimed to have fixed the problem, though the engine is still leaking a significant amount of oil. There is a significant amount of data on the web that addresses this oil line and the associated issues. 3. Part was replaced, but with same type (part number, composition, etc. ). Basically, a "new" bad part was replaced. Furthermore, the first dealership installed various gaskets and seals incorrectly, and still gave the car a safe rating for a 600 mile trip. The second dealership merely replaced a bad oil line with another bad oil line.

The vehicle experienced an oil leaked.

After my engine registered "low oil", the mechanic found significant sludging. It was flushed and changed and then in <1000mi there was no oil again. Now Toyota says the leaks around the valves are due to my "neglect" in changing oil. I have the receipt from 4 mos ago for oil change. I also was told they would not consider paying for it because it was my lack of oil change that "caused" the sludging (despite my receipt) and that I needed all my oil change receipts for them to consider a claim (2 1/2 year old car. ).

Engine has failed due to oil leaking at piston rings/sludge. Toyota claiming improper maintenance. Have maintenance records for oil changes at intervals better than recommended. Toyota claims denied because service not performed at Toyota. Estimate from dealer for repair is $8,300. There appears to be some other problem with this engine but they won't investigate further due to sludge even though I can prove proper maintenance.

Vehicle did not pass vehicle emissions test, dealer said that dirty oil had leaked into the engine causing engine sludge, repairs were not covered under warranty, owner stated that the oil was changed regularly, and knew of other similar cases, onwer is concerned that this condition is a result of a manufacturing or design defect.

Initially oil leak after oil change. Was told that transmission pan was leaking and paid for replacement. Transmission fluid then started leaking. Returned vehicle to dealer; transmission pan was tightened. Noticed fluid still leaking; returned vehicle to dealership. Dealership could not detect source of fluid leak; placed die in oil and transmission fluids; asked to return vehicle in a few weeks. Returned vehicle to dealership; was told there was a leak surrounding engine seal and seal would need to be repaired.

While having cam seal/valve seal replaced due to an oil leak, mechanic noticed right front passenger tire had a bubble and was replaced by firestone, consumer states vehicle is going back for a 3rd time for the oil leak.
