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.

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…

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.
