On 03/22/2010 Toyota replaced a vvti oil hose under recall # 90k because the rubber portion of the hose was subject to failure that would cause the engine oil to spay out. On 07/24/2012 the replacement hose ruptured causing engine oil to spray out. The engine oil soaked the serpentine belt which is attached to the power steering pump as well as other components. This caused a loss of steering control which nearly caused an accident.
After arriving home, I pulled into garage and noticed an odor of burning oil. Upon exiting the car, I saw a trail of oil from the back of the car up my driveway, extending up to the street. Looking under the car, I noticed oil dripping from the engine area. I found that I lost all engine oil without any warning lights or sounds advising me of the problem. Fortunately the loss of oil only occurred in my driveway and garage area. My car had to be towed to dealer. They installed several gaskets, a timing chain cover, a fipg oil pan, a belt (v-ribbed), non-chlor brake c, a replaceable eleme, another gasket, a pipe sub-assy, 0i. Since oil was sprayed in engine area, they had to wash engine off. Upon researching this oil loss problem, I find many other 2006 Toyota Avalons have experienced exactly the same thing. If I had been driving on the interstate, I am sure my engine would have quit on me with no warning and could have resulted in a bad accident not to mention the destruction of the engine itself.
