Driving down highway noticed white smoke coming from car. Exited highway and warning light then came on saying engine oil low. Stopped van immediately on side of the road and had it towed. Appears the oil coolant line burst which is a known issue on these vehicles after google searching, but was never made aware. Always completed all recalls. Extremely dangerous especially with children in car.

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 dollars for tow truck / $148.14 on Toyota original parts / $270 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.

Millions of people could be stranded in the middle of nowhere if they do not know about this negligent design flaw. Toyota designed an rubber oil hose that gets stiff and breaks. This is design negligence to use rubber hoses on an oil system. Toyota redesigned this part with steel instead of rubber.this shows me they knew the design was bad in the first place. Van's ABS and vsc lights come on but no oil light warning. My motor started making noise but I didn't know it ran out of oil. There was no oil warning light. I didn't know it was the motor making noise. My car engine was completely out of oil. Again, no oil light warning. Since I found out about this, I found out about four more Sienna's that had the same defective parts. Frankly all of these hoses will go bad as the mechanic remarked about this problem car engineers know exactly what they are doing when they design a car. I worked in manufacturing and engineering those parts are well documented when they are predicted to fail. One would consider two scenarios. 1.they had bad engineers designing this system, however car manufacturers know exactly what they are doing when they design a vehicle. 2.or they designed it to break to sell more replacement engines for four thousand dollars each. They kept this a secret or made no mention of this probably to sell engine replacements. The Toyota manager called me and basically told me tough. Therefore I will be suing them in small claims court. Hopefully Toyota will be replacing my motor. By the way I take very good care of my vehicles I maintain them with regular vehicle inspections along with oil changes at the prescribed mileage.

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.

My van cut on fire last saturdar, September 1st 2019. For no apparently reason. I drove about 5 miles from my house to the grocery store, when I notice the smoke, I first though was the car in front of me. But was smoke coming from my hood. I was just about to stop at a stop sigh and I look the temperature gate and it was fine, turn of the car and people from the parking lot was already yelling for me to get out of the car. More than 2/3 of the van was totally destroyed in the fire.

The contact owns a 2011 Toyota Sienna. While driving, the engine oil cooler pipe burst and spewed oil all over the rear of the vehicle. The vehicle's rear window was completely covered with oil. The manufacturer extended the warranty; however, the contact was not covered since the vehicle exceeded the warranty. Buckeye Toyota (1903 riverway dr, lancaster, oh 43130, (740) 654-3943) stated that they could not authorize a repair out of warranty unless approved by the manufacturer. The manufacturer provided a case number and stated that they would not cover the cost of the repairs. The contact called the state attorney general's office. The vehicle was not diagnosed or repaired. The failure mileage was 156,000.

Oil cooler hose: From my experience, and from what I've read from others, this is a considerable safety issue. A recall would be very appropriate for both road safety and for consumer protection. A suspected blown cooler line just happened to me last night, and I was very distracted when I realized my 2011 Toyota Sienna (about 125K miles) went from providing normal responsiveness to giving incomprehensible feedback within seconds. A "low oil" message flashed once on the center console as I was pulling out of a gas station into traffic. This light did not return. No other lights lit up at any time. Immediately, however, I noticed hesitation when trying to accelerate. I thought that it was an electrical problem at that point, perhaps it was affecting the fuel injectors. Then I noticed a clicking noise coming from the engine. At that point, I pulled over at the next safest opportunity and turned off the vehicle. I popped the hood and noticed oil everywhere toward the bottom of the engine compartment/underside of the vehicle. The dip stick was dry. This all happened within 0.75 miles on a two lane state highway (one lane in each direction) with a 55 mph speed limit. I certainly wasn't driving defensively during this time, and I had very minimal awareness of any vehicles around me. The acceleration issue could have been catastrophic if I had tried to beat traffic that was far enough away to proceed, yet close enough to think twice. Fortunately, I'm not an aggressive driver, and I waited. The whole experience has baffled me as I've never experienced such a complete and sudden failure while driving a vehicle. Please consider this report and review the numerous online reports from drivers who also experienced a sudden, massive oil leak while driving their 2007-2011 Toyota Siennas. Toyota is well aware of this recurring issue. A safety recall would seem appropriate.

The minivan suddenly, with no warning or indication rapidly lost all engine oil in a short period of time. As I was driving on a city street, I got a warning about five minutes into a drive about low engine oil pressure, when it was basically dry. I had it towed to a mechanic where it was quickly confirmed that the oil cooler pipe had failed causing this to happen. I have 120,000 miles on the van.

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 started leaking heavily; I was notified by a coworker and was able to get the car into Firestone before the engine locked up. Low oil pressure warning came on as I drove into Firestone lot. Techs told me the oil cooling hose failed (at 109000 miles). Old hose was made of rubber attached to metal plates and had failed two places in the rubber hose. New hose is made of metal so techs checked for a recall and found none. This could be a big safety issue if people are not aware of what is happening and get stranded somewhere or the engine locks out on them at speed.

Hello, I own a 2011 Sienna le V6. In cold weather, it has a problem when braking where the vehicle lurches forward as it comes to a stop. The dealer drove the car and noted no issues. However, as you can see on this internet thread, many other owners have the same issue. www.siennachat.com/forum/193-problems-maintenance-repair/158410-engine-revving-up-just-before-stop.html this issue is not just annoying, I believe it is a safety issue, particularly on slippery surfaces such as snow and ice which are likely to occur in the colder weather that precipitates this issue. I believe either the engine or transmission programming needs to be modified to address this issue as soon as possible. This occurs when the engine is at high speed idle after a cold stop, which can last for many miles after you start driving.

Car started rolling back and gear shifted to reverse when it was on drive gear. It shifted to gears automatically without changing gears. When went to dealer, they said its transmission is failed at 55 K miles. It was in warranty and they changed transmission but when asked they didn't give me much detailed information. My 1 work day was spoiled and inconvenience.

9/1/12 I was driving along at highway speed of aprox. 55-60 mph when I decided to go into a shopping center. I slowed my car down and made a right turn to enter a shopping center. As I was slowing down to pull up to the entrance of the store I had my foot on the brake pedal and the car didn't want to stop. I had to apply an enormous amount of pressure to the brake but it didn't stop the engine from racing and trying to lurch forward. I forced the car out of drive and put it into reverse and the engine went back to normal. 9/6/12 I was in my car and approached a traffic light behind another car. I slowed down from aprox. 25 mph. As the car slowed I felt the car lurch forward, I applied the brake harder so as not to hit the car in front of me or the people walking across the street. I again moved the car out of gear and the engine came to normal. 9/9/12 I was in a shopping center waiting for my wife to come out and I had to move my car to let someone else get out a parking space when my car started to accelerate. I had my foot on the brake at the time this occurred and as much pressure I put on the brake was not enough to stop the car. The car still had enough power to go forward even though I had my foot on the brake. I fear for my life and any people that are in my car, let alone outside of my car. Toyota cannot duplicate the problem, I've taken it to them twice. They (Toyota) will not do anything for me. Please help.
