While driving ,without warning, the "v v t I oil line" burst, draining all the oil from the engine. There is loss of power with possible engine failure. At time of incident, leaves oil on road and windshields of any cars following. ( this problem has occurred on Toyota's v-6 engines since 2005. There has never been a recall. . . It only "quietly" gets repaired as you bring the car in with this problem. Toyota has changed this part 4 times with no recall. They have fixed the problem on the 2009 engines, replacing the defective rubber hose to a solid metal oil line. Toyota has known about this since 2005, and now with the gas pedal problem, want to hide the "recall" at the same time. . . . . . . . Problem is they put the same rubber part in . I paid $240. 00 to change the part to the new all-metal part the 2009 and newer v-6 engines have.
