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.
