Engine Failure Problems of Toyota Sienna

The engine failed while entering the highway. All power was lost and vehicle had to be towed to the local Toyota dealer. I was informed today that in order to analyze the problem the engine needs to be removed at $140 per hour approx. 20 hrs of labor. I have given them permission to do this so I can receive a quote as to how much to repair. This Sienna was just in for 125,000 mile service with no known issues. I do not have any type of documentation as of today June 4,2018.

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. 00 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.

I put my car in the shop at coleman Toyota telling them the car wouldn't start. They replaced the ignition chamber and then phoned to say the starter was bad too- they charged me about $575. I picked up the car Wednesday March 15 and on March 16 the car just stopped as I was driving to work. The car had to be towed to coleman Toyota. They phoned to tell me the engine had "locked" and the car was shot. They refuse to refund me the $575 for the unnecessary repairs and refuse to acknowledge that the engine failure due to "gelling" is a manufacturers defect.

Engine light came on in my 1998 Toyota Sienna on i75 in atlanta GA while visiting friends, was able to get to median before it died. Had it towed to independent mechanic who verified sludge build up. Called Toyota about engine failure. Was told to take van to a Toyota dealership in SC (where we live) towed the van home took it to dealership who also verified sludge build up. Was told by Toyota that they were aware of the problems in their engines but was not going to pay for engine replacement because we did not have receipts proving that oil/filters changes were made. We changed our oil every 3000 miles without fail. If we didn't engine would have died sooner. Toyota did say that we could pay for repairs $9000 and then submit receipts for review and may be reimbursed for repairs. Still fighting with Toyota, have made complaint with bbb. Police were called to the scene, I was alone with 4 children.

The engine in my 2000 Toyota Sienna has a defect that causes engine oil jelling and leads to a total failure of the engine. The problem first occurred at 38000 miles while still under the new car warranty. Toyota fixed the problem by cleaning the sludge from the value area of the engine but this did not eliminate the problem. At 68000, there was a complete failure of the engine that was a result of engine oil gelling. A Toyota technician who inspected the car stated that there is scaring of the internal engine parts that indicate a history of oil starvation. The oil starvation problem that caused the engine failure is due to oil gelling problem. Toyota has agreed to extend the warranty on my vehicle to cover this problem for a period of eight years with unlimited mileage, however, they are now refusing to honor this warranty.

Waiting to hear from Toyota on our oil sludge engine failure problem. We are gathering the oil change receipts and were 1st told we did not maintain the vehicle. Now seeing that we are not alone with this issue.

My car's engine failed at 20,000 miles. The dealer said it was due to sludge, based on my not changing the oil often enough. I had changed the oil every 6000 miles, not every 3000 miles. The dealer, jim coleman Toyota of bethesda MD stated that I was at fault and that Toyota would do nothing for me. First coleman flushed the engine, at a cost of 1000. When this repair only held for 2000 miles or so, I was told I needed to replace my engine. I did so at ernie's, a top-rated repair shop in bethesda (consumer check list)at a cost of 5600, considerably less than Toyota's price of 7500. I have faithfully changed my oil since that time on or before the 3000 mile mark. The engine has again failed due to sludge build-up!!! I am now expecting that Toyota will replace the engine at no cost to me, but I am concerned that there will be some catch to this. . .

Excessive sledge build up in engine which caused engine failure. Manufacturer notified, and refused to honor warranty. Feel free to provide any further details on this matter.

Our Sienna was diagnosed with sludge buildup in may 2000. We were told it was necessary to replace the engine as eventually we will encounter engine failure at some point. Toyota refuses to take responsiblity of this matter and continually blames the owners for lack of maintanence. There have been other owners who have encountered engine failure while driving. We are fortunate to not have had that. However, we have no peace of mind in driving this vehicle every day, with our children mind you, and knowing we could have engine failure at any time. It is very important that an investigation into this matter be done. It is obvious there is a problem as Toyota has had over 3000 complaints such as ours. It is only a matter of time before someone is injured or killed as a result of Toyotas negligence in this matter. Is there a stipulation that someone nust be injured or killed before an agency such as yours will investigate? that makes no sense. When there is a potential for injury you must follow through. Please.
